Different Sex Story

byrichman3©

Dear readers, once again I highly advise reading parts 1-3 before reading this part as the events pick up exactly where part 3 left off. One other note, I know I promised to go back to Chloe and Bill. However, I just can't let go of my two lovers in the backseat. So, this part will focus mostly on them again. Chloe and her dad will return in part 5.

**************

Still licking my son's cum off my fingers, I ran my other hand up and down his chiseled abs and chest. Completely spent, Jason, collapsed onto the seat next to me. I moved over to him, and he put his arms around me.

I was content. A feeling of complete satisfaction overcame me, and my eyes soon got heavy. Both of us were completely naked, and we soon fell asleep in each other's arms in the back seat of the big Ford Expedition.

Sometime later I awoke, and I heard somebody talking faintly. Slowly opening my eyes and stretching I looked around. I noticed two things. It was now fully dark, and the car was no longer moving. Then I heard the voice again. "Come on you two wake up we are here." I heard my husband's slightly aggravated voice from the front of the vehicle. I looked down and gasped. "Oh shit."

Realizing that I was still naked, I looked over at Jason, and he was just stirring a little bit; he too was unclothed. I moved his arm from around me and shook him.

"Get up," I whispered loudly. His eyes fluttered open, and he looked at me and smiled.

"Okay, honey," I called to my husband as I began to scramble around looking for my clothes.

Jason's eyes opened wide as he finally realized the situation. "I'm gonna go into the office and get us a couple of rooms," Bill said as he opened the door of the car, causing the interior lights to go on. "Hurry," I said to Jason, as he too was now actively trying to put his clothes back on.

I glanced out the window at my husband as he walked towards the office. I said a silent wish that he wouldn't turn around to look at us. Even in the dark, there was no way that anybody actively considering the backseat of our car wouldn't notice that both my son and I were still very much naked. I had no idea how I would explain things to Bill if he noticed us.

As I scrambled to pull up my shorts, I kept an eye on Bill as he walked over to the office. Thankfully, he never looked back towards the car. As I got my shorts back up, I realized something else. I had no button.

"Shit," I said aloud as I fumbled to try and keep them up. How the fuck was I going to walk from the car to the room without anybody noticing that my shorts were unbuttoned?

The only thing that might help me was that they were a little tight. I could perhaps walk to the room without them falling, but there was no way I could hide the openness of the shorts. The area just above my pussy between my belly and vagina was completely open, and the skin was very visible.

As I pondered this, I heard my daughter from the front of the car.

"What the hell are you guys doing back there?"

"N-nothing," Jason said unconvincingly as he put his shirt back on. He looked down onto the floor and found his shoes, and he quickly began to put them back on his feet.

"Just don't worry about it, Chloe." I snapped. "We just woke up is all." Though my tone wasn't convincing, I hoped it was enough to keep her from asking any more questions.

"Are you sure you guys don't need any help?" she asked as I heard her unbuckling her seat belt.

"NO," I said much louder than I wanted to.

"Alright, shit," Chloe said, chagrined. "I was only trying to help. Be a bitch, why don't you." I felt bad for snapping at her, but her response immediately pissed me off.

"Just stay there," I retorted. "We are fine, and mind your own business." I still felt bad about yelling at her, but I couldn't let her see us like this. Jason was now almost dressed, but I was still half naked. I couldn't find my shirt. "Dammit," I said again as I scanned the floor looking for my t-shirt.

Finally, I saw it peeking out from underneath the seat in front. I leaned over and grabbed it. As I did, I felt Jason's hand on my bare back. I looked up at him and smiled. He gently moved his hand up and down my naked skin. Then I leaned back up. I pulled my t-shirt up over my head and put it on. It was short and tight. I tried to pull it over the gap in the shorts, but the shirt was just too short to reach.

I found my flip flops and used my toes to put them back on my feet. My mind racing, I looked out the window and saw Bill returning to the car. I looked over at Jason.

"You've got to distract them when we get out of the car," I whispered. He looked at me puzzled then I pointed down at my bare skin above my pussy.

He laughed. "Oh, shit did I do that?" He said. Angrily I said. "Yes, now how the hell am I supposed to walk around like this?" He smiled again and then I did too. "Come on please." I pleaded.

"Okay okay," He said still chuckling. My husband got back into the car and pulled forward. Bill moved our car over towards a parking space in front of a door. "Okay everyone get out, and I will park after we get some luggage out."

Chloe immediately got out of the car and headed towards the back. Jason moved forward with me close behind. He tried to block my view from Bill as we opened the door. As soon as my feet hit the pavement, I moved closer to the car doing everything I could to hide. Jason moved towards the back and helped Chloe open the door and get our suitcases out. I remained on the side of the car my waist out of view of both Chloe and my husband. I hoped anyway.

Jason quickly found my suitcase and handed it back to me. I grabbed it and held the case in front of my crotch. After Jason and Chloe got, their luggage Bill said. "Honey come here, and I'll give you the room keys." I froze not knowing what to do. I couldn't risk getting close to him. Then Jason saved me. "That's okay dad I got 'em." He said and ran around to the driver's side door.

I looked over, and Chloe was staring at me. She had a very strange expression on her face. "Did you have fun in the backseat with Jason, mom?" she asked with a weird glint in her eye.

"Sure, it was a load of fun listening to your brother snore," I said, trying to cover.

She smiled. "I bet it was."

"What's that supposed to mean?" I said a little annoyed.

"Nothing," she said. "I just thought maybe you two had a chance to bond over the last few hundred miles that's all." The way she said "bond" caused my heart to beat a little faster. Did she know something? Or was she just being her usual bitchy self?

"Dad just said that you two had to talk about a few things," she said. "I was wondering if you two talked is all?"

Again, she emphasized the word "talk." I was more than a little suspicious especially because I was standing there with my pussy hanging out.

"Yes, we talked," I said flatly.

"Okay," she said, smiling. Her manner seemed to indicate that she was dropping the questions. I sighed in relief. Jason came over and handed me my room key while Bill pulled the car away.

"Here mom," he said. "You better get your bags inside they look heavy." He winked.

"Chloe, do you need any help with yours?" Jason said, walking over to her. She handed him her bag, and they headed inside. I quickly followed. Eventually, we arrived at our rooms, and my two kids went inside theirs. I had to set my bag down to use my key nervous I looked around, and thankfully nobody was near. I quickly used the key and went inside. I sat the bags down onto the bed and breathed a sigh of relief.

"That was way too fucking close Liz," I said out loud and to myself.

Realizing that Bill would be here soon, I hurriedly stripped out of my clothes and put on a robe. I heard a knock on the door. I opened it, and Bill stood there.

"Wow, you must really have wanted to get out of those clothes," he said as he moved past me.

"I'm gonna take a shower," I said, moving towards the bathroom. Then, just as a sort of test I removed my robe and threw it onto the bed. I stood there naked in front of my husband for a few seconds.

He barely glanced up at me as he said, "You better take a towel with you. I don't trust these motel towels." He handed me one from one of the suitcases sighing I took it and headed into the bathroom.

"You didn't even look at me," I thought to myself.

The evening was pretty much uneventful. Bill took the car and got us all a pizza. Jason and Chloe ate in their room while we ate in ours. My husband and I told them they could order a movie if they wanted and we parted ways until morning. Both Bill and I went to bed early as we were equally exhausted for different reasons but still very tired.

My thoughts kept me up late as my mind was in turmoil over the events of the day. I had been more immoral with my son in the backseat of our car than I ever had been with Bill in our marriage. The thought both scared and aroused me.

I looked over at Bill sleeping and sighed. We hadn't been intimate for a long time, but I didn't hate him. He was a good man and a good provider. In fact, this move and promotion were going to make things better for our family. Knowing all of this I still couldn't get the feeling of my son's massive cock out of my mind I realized I was completely infatuated with my son.

Then I thought about the implications of everything that had happened and almost happened. What if Bill hadn't called back to wake us up? What if he had instead waited until after he got the keys and sent Chloe back to wake us up or worse crawled back himself.

I shook my head in shame thinking about what would have happened if he had caught us lying there naked on the backseat wrapped in each other's arms. Dried sperm on my pussy and all over the seat. It would have ruined not only my marriage but my family.

How would Chloe react to that? She would hate me forever. Bill would be both furious and disgusted at my actions. Divorce would be the least of my problems if people found out about what happened. Sure, we were moving to a new town, but we still had friends and family. I would be the disgrace of the family. I had knowingly committed incest with my son.

Then my thoughts turned to what did happen. Again, I was torn, thinking about how Jason had cum inside of me. The thought had my pussy dripping wet as I sat in bed next to my husband. What were the implications of that?

It had been at least three weeks since my period, and I knew the chances were good I might be ovulating. So why had I told him to do that? I didn't know. Did I want to have a baby with my son? That would be catastrophic, or would it?

Eventually, while lying there, I realized I had been so caught up in the moment that suggesting my son cum inside of me must have been some crazy way to further increase the intensity of what we were doing.

Thinking about all of these things as I lay there, I finally made a decision. I wasn't going to fuck my son again. I couldn't. Even though it had been beyond satisfying, I simply couldn't risk it again. Jason would probably be hurt, but I knew I had to be the adult and stop things now.

I also decided to try and find a pregnancy test somewhere along the way and find out for sure. If I needed to do something I needed to do it soon. Finally settling on a course of action, I fell into a nice deep sleep.

At one point during the night, I awoke to a sound. I reached over and felt only a pillow where my husband should be. Rolling over I saw a light on in the bathroom. He probably just had to pee, I told myself and turned back over falling right back to sleep.

The morning came, and I woke up feeling pretty good. I knew what I had to do and I was determined to follow through. I had a weak moment in the shower where my thoughts once again turned to my son, but I pushed those away and resolved to take steps to limit my temptation.

We all ate breakfast at the complimentary fruit and cereal bar. Bill announced that he wanted to make better time today. He said that he was distracted yesterday and we fell a little behind schedule. Chloe didn't seem like her usual moody self, in fact, she seemed downright happy until I made my announcement.

"I'm going to ride up front today," I said. Chloe immediately stopped playing with her phone and looked up at me.

"But you can't mom," she said as if it were a fact.

"Sure, I can and I will," I said flatly.

"But . . .." She stopped. "I like riding up front with daddy," she said, almost whining.

"I want to talk to your father," I said undeterred.

Jason had a puzzled look on his face. He even looked a little sad, but he didn't say anything. Chloe spoke again.

"You can't, mom," she pleaded. "I got everything all set up for myself there, and I like to look out the front window."

"I don't care. I want to ride up front today," I said, realizing I almost sounded like my daughter.

"It's not fair," she said and stormed away towards the bathroom.

Then Bill spoke. "Honey, why don't you just let her have her way?" he asked. "You know how she gets. She will just complain the whole time and drive everyone else crazy. I really do want to try and make some time today, and I just don't see how I am going to do that with Chloe complaining the entire trip."

Then Jason chimed into the conversation.

"Besides mom, don't we have more to talk about today?" he asked, the innuendo clear in his words.

I looked at both, and, finally, I sighed in resignation.

"Okay, fine," I said. I realized I couldn't protest anymore without drawing suspicion. It seemed the day wasn't starting off how I had planned at all. Chloe returned from the bathroom, and Bill told her the news. She instantly brightened and turned to me.

"Thanks, mom. I promise to be as helpful as I can be from now on."

I looked at her, not understanding what she meant by her statement, but she seemed happy and, amazingly, joined the rest of us in the conversation for the remainder of the meal.

Climbing back into the car, we all settled into our seats. I glanced down at the back seat and noticed the dried cum from yesterday. In our hurry to get dressed we had forgotten to clean up. I pulled a couple of wet naps from my purse and wiped down the seat as best as I could.

The back of the car still smelled of sex and a part of me was turned on by it. I tried, I really did, but my thoughts immediately returned to yesterday as I cleaned the seat and looked over at my son. "God his cock was great," I thought to myself. In terms of size, he was about as big as his father, maybe even a little thicker, but it was the stamina on that boy that got me.

Jason sure knew how to use what God had given him in a way that his father never did.

"Dammit stop it, Liz," I scolded myself internally.

We were soon underway, and the car was relatively quiet today. This was a stark comparison to yesterday when the volume on the radio had blasted for most of the trip. Jason and I both pulled out our Kindles and started to read. I actually started to get into my book.

Some time passed, and I thought maybe my plan would work. Then, at one point I looked over at Jason, and he smiled at me. I returned the smile without thinking. He took this as an invitation, and he scooted over to get closer to me. I felt his hand on my bare leg again.

This was exactly how things had begun yesterday. I got goosebumps, and I allowed it for a few seconds before I sighed and moved his hand away.

"No, Jason," I said.

He looked at me. Then he moved his hand back to my leg again. I quickly moved it away.

"I said no." This time I said it more sternly.

His brow furrowed, and he looked towards the front and then whispered, "What's with you today? First, you don't want to ride back here. Now you keep moving my hand."

He looked at me, expecting an answer of some kind. I sighed again and spoke in a whisper.

"Look, honey, what happened yesterday was great. Phenomenal, even, but it can't happen again. Okay?" I said, looking him in the eye.

"It's simply too risky," I said, pointing up front at Bill and Chloe.

He looked at me, puzzled. "I'm not afraid of Dad," he said.

I shook my head.

"It's not about that. It's about everything. There is too much to lose. It simply can't happen again."

Jason looked crestfallen, and my heart broke for him. He was simply too young to really understand. At 19, he couldn't comprehend the realities of life -- how what we did could have major consequences.

"Look, honey, I'm sorry but we just can't okay." I tried to be firm.

He looked at me. "Did I do something wrong?" he asked. Again, I felt sorry for him.

"No honey, it's just the situation there is too much to lose, and it's my fault anyway. I should never have allowed things to go that far."

I put my hand on the side of his face. He grabbed my hand and kissed my fingers. I immediately felt a tingle in my pussy. Shaking my head, I pulled my hand away.

"We just . . .." I said, pausing. "We just can't do it again, okay? We will always have that little secret between us, but it can't happen again. Okay?" I said it firmly. "Now move back over to your side of the seat."

He slowly did as I instructed.

"Okay, mom, but I don't think you understand," he said and moved away.

Now it was my turn to look puzzled.

"What do you mean, 'understand?'" I asked.

He shook his head. "This is the way you want it, so you don't get to ask," my son said.

I became a little angry. "This isn't a game, Jason. Now tell me what you mean," I said resolutely.

"I mean that you don't understand that I get it," he said, looking into my eyes again. "You think I can't realize the implications of what happened and the consequences of our actions, but I do. It's you who doesn't grasp what yesterday really meant," he said.

Now I was puzzled. "What are you talking about?"

"I mean you, and I are meant to be," he said flatly. "I love you mom not just like a son, and you love me, you just don't want to admit it to yourself."

I looked at him, surprised.

"Think about it, mom," he continued. "The last several months -- everything that has happened between us and maybe even before that. What happened yesterday wasn't just some spur of the moment thing. You and I have been dancing around each other for a long time.

The opportunity just had never presented itself until now, that's all." He looked right into my eyes now. "Think about it. The art class and everything that happened after. Don't tell me you didn't go home immediately after that and play with yourself."

I gasped for a second. How did Jason know that? We hadn't even talked about it yesterday before everything happened.

"Then there was the time you came to my room naked and later the pool. Do you remember?" he asked.

"Of course," I said. "We talked about it a little yesterday."

Then there was the day in the bathroom when you came in while I was shaving," he said. "You watched my dick get hard, and then as you were leaving, you said to yourself how big it was. So, you see, mom, this wasn't just something that happened. Things had been building long before that."

I looked at him, not saying anything. He was right. I had been fantasizing about him for a while. I just didn't want to admit it to myself, and yesterday I just had simply let go. I had allowed things to happen that I probably shouldn't have, but a part of me knew it felt right.

Sure, he was my son, but Jason made me feel different. He made me feel like I was 20 years old again. The logical part of my brain knew that this was just some kind of animal attraction to a man who looked a lot like the man I had married and who made me feel like my husband did when we first met. It wasn't love as he had said, but it was something very strong. Or was it love? I wasn't sure anymore. My son had thrown a wrench into my well-laid plans.

I was attracted to him, and maybe I had been attracted to him before the art class. Jason had always been my favorite if truth be told. Sure, I loved my daughter, but Jason always had been the one I gravitated towards.

He was strong and mature for his age, and when his father and I started to have problems, Jason was the one I relied upon. I pondered all of this while sitting in the car next to him. Then I kicked off my flip flops and put my feet up on the seat. With my knees bent I placed the Kindle on them and tried to get comfortable.

I had done this before in the car when we had taken trips, and I thought nothing of it. Jason said one more thing before he was silent.

"The truth is, mom, you wanted what happened as much if not more than I did. You just can't admit it."

I looked at him then back down at my book. We sat in silence for a long time after that.

My mind continued to race as I sat there trying to read. I thought about everything my son had said, and I thought about myself. Last night I was so sure I was making the right decision, but now I wasn't so sure.

A part of my brain screamed at me that I was bargaining. That I was trying to convince myself that doing something wrong was actually right. Of course, that was part of the attraction. Knowing that what we did was against everything moral society said you should do had made it even hotter. My pussy began to get wet.

Back and forth my mind weighed each option as I sat there trying desperately not to think about him. I strained to avoid looking at him, but every once in a while, I stole a glance at him, and the butterflies returned to my stomach. Riding there next to him was becoming excruciatingly frustrating for me.

My book almost forgotten, I just sat there with my thoughts wandering and my pussy becoming wetter by the minute. I looked over at him again, and I caught him looking at me. He glanced down at my bare feet and painted toes. I smiled. I just gave up at that moment.

Suddenly whatever force had been trying to get me to do the right thing was gone. I knew at that exact moment that I was going to fuck my son again. It happened so suddenly I wasn't prepared for it. My inhibitions just left, and I gave in to my desires.

I tried. I truly did. I had done everything I could to prevent what happened next. Unfortunately, in the end, Jason was right. I glanced over at him again.

"Jason, honey," I said.

He looked up from his book and over at me.

"Move a little closer to me will you," I said in a soft, seductive whisper. Jason narrowed his eyes but then did as instructed, scooting his body away from the side of the car and towards the middle of the seat.

I moved my left foot and placed it on his lap. With my right foot, I began to gently rub his leg up and down while my left foot started to massage his crotch. He looked up at me and smiled with lust in his eyes.

"Are you sure mom, because before you said . . .." He stopped when I put a finger to his lips.

"Shhh. Just go with it, baby."

He grabbed my finger and sucked it with his lips. Electricity running through my body, the anticipation of what was going to happen had my panties soaked.

"Now do something for mommy," I said as he sucked my finger.

He looked at me.

"What?" he asked.

"Take out your big cock. I want to see it again," I instructed. One final desperate plea came from my conscience to stop. Ignoring my conscience, I watched as Jason began to unbutton his pants. Licking my lips, I waited while he unzipped his fly. He lifted his ass up and pushed his pants down to his ankles.

His cock immediately sprung up. It wasn't fully hard yet, but I watched in awe as it began to rise. I moved both my feet over towards it. Again, electricity shot through my pussy as my bare feet touched his warm cock.

Jason let out a little gasp as I began to massage his cock with my feet gently. I had never really done anything with feet before, but I was familiar enough with the concept. I hadn't ever planned to do anything like this; it just sort of happened given the situation we were in.

"Jason honey?" I asked.

He looked over at me while my painted toes continued to stroke his now very hard cock.

"Yes, mom."

"I'm sorry baby. You were right." I paused. "You were right about everything, and now I'm going to make it up to you, in spades."

We locked eyes. He moved closer to me, and I leaned forward. Our lips met, and we kissed. Jason grabbed my head and pulled me towards him. Our kiss became even harder as I finally let go and gave fully into my desire for my son. Our passion was animalistic.

Every reservation I had was now gone, and my craving for Jason was uncontrollable. Nothing was going to stop us from re-consummating our lust for each other.

"How could I have been so stupid," I thought as we kissed. I felt like I was home.

Jason leaned back against the side of the car. Looking around I grabbed a bag from the back and propped it up against arm rest. I, too, too leaned back and put my feet back in his lap.

Using my dark red painted toes, I gently stroked his cock. My son gasped with pleasure as I worked his cock with my feet. I put the head of his engorged cock in between my big toe and my second toe, and I worked it up and down. Next, I placed both of my feet around his cock and began to stroke his dick with them. It was a little rough and Jason spit on his cock to give us some lubrication.

"Oh my god," I thought. It was so fucking hot. Never had I done anything like this before. It was something I had always wanted to try, but Bill had never wanted anything to do with my feet. I kept working my son's cock until my calf muscles began to tire.

I stopped and pulled my feet back. Jason looked over at me longingly. I smiled and turned my body around. Facing him directly, I dove into his lap.

I wasted no time going to work on his cock with my tongue. Swirling my tongue around the purple head of his dick, I eagerly lapped up the precum oozing from the tip. Next, I ran my tongue down his shaft. I shivered as I felt the huge tube pulsing beneath the skin of his cock. Finally arriving at his balls, I took each one in my mouth and sucked hard.

As I released each one, it made an unmistakable popping sound. I glanced up toward the front of the car, but there was no response from my husband or Chloe, so I continued. The music was playing from the radio. Again, not as loud as yesterday, but it must have been enough to mask what we were doing back here.

Sucking and licking my son's balls, I eagerly continued my assault. Stroking his massive cock with one hand and licking it with my tongue, I soon covered his dick in saliva. I ran my tongue up his huge shaft once again and arrived at the tip. I looked up at Jason and our eyes locked again.

Saliva running down my chin, he leaned over and kissed me. Our tongues massaged each other as I continued to jerk his cock with my right hand.

When our kiss broke, I smiled at him and said, "Remember yesterday?"

He looked puzzled at me. Then I dove back into his crotch and promptly impaled myself on his cock. The incredible feeling of his cock penetrating my throat was fantastic. I love the sensation of a cock sliding over my tongue and to the back of my throat. Within a second I felt hands on the back of my head pushing me further.

I did not resist. I wanted to choke on his cock. I realized as I had my son's dick all the way down my throat that nothing would ever feel so good or so wrong as gagging on Jason's dick. What I was doing was so depraved I felt like a dirty porn star, and I loved every second of it.

He held me down as I began to try to pull back instinctually. Gagging sounds could be heard in the backseat as I struggled to keep his cock in my throat. Oxygen was starting to become a problem, and I tried to breathe through my nose, but I could feel myself starting to pass out. Mercifully, Jason released me, and I came up for air.

"Huuugghhh!" I gasped for oxygen. Coughing and spitting I began to focus again. It was then that I heard my husband.

"Liz, what's wrong?" he called back.

"N-nothing hun," I said with spit running down my chin dripping onto my shirt. "I just have a tickle in my throat that's all." Then I went back to licking and sucking Jason's cock.

"Are you sure? It sounds like a pretty big tickle," Bill said.

In between blowing my son, I responded.

"Honey you have no idea how big it is," I said, "but I'm fine."

Remembering that I got caught doing the same thing yesterday, I added, "Maybe I'm coming down with a cold. It could be a big one too."

Ignoring the danger, I swallowed my son's cock again.

"Alright, as long as you're okay," Bill said.

Then Chloe spoke up. "Daddy I love this song," she said.

The radio volume went up in the front. I barely noticed as I once again began choking on Jason's dick. With my son's hands pushing my head down as far as it could go, I felt his cock go deeper than ever before. The feeling was amazing.

Every second his cock was down my throat was ecstasy. I wanted to be a complete slut for my boy. As I began to choke and my body tried to pull back once again, Jason held me down. As I struggled, I thought again about how stupid I had been to resist this. All of my life I had done the right thing. I had been a good girl for the most part.

Sure, I did the nude modeling, and I had flirted with the professor, but nothing had ever happened. The truth was, even before I met Jason's father I had never really done anything all that outrageous regarding sex. Bill and I had done a few experiments as most married couples do but nothing like what I was doing to my son right now.

I realized as I had Jason's cock all the way down my throat that I wanted to be a slut for him. Every depraved sex act that he wanted to try I was now up for whether it be today or in the future. Like before, just when I thought I couldn't take it anymore Jason released me and I came up for air.

As before I coughed and spat while my right hand continued to stroke his very hard cock. Thanks to Chloe, who had unknowingly helped us out with the music volume, nothing came from the front except music. I started blowing him normally, licking and sucking his immense member. I felt a hand go down my back and into my pants. Jason moved his fingers inside of my panties and began to rub my dripping pussy while I kept sucking his cock.

At one point, I felt something else that caused me to yelp in surprise. He had stuck a finger in my ass. It didn't hurt, but his finger surprised me. I came up from his cock.

"What the hell are you doing?" I asked.

He smiled over at me. "Payback."

After a second I smiled. "Okay fine but don't do that again," I said.

I wasn't sure, however, that I didn't want him to do that again. I pushed those thoughts away, for now, focusing on his cock. He kept fingering me, and I kept sucking on his dick for a while. At one point, I even gritted my teeth a little on his dick as my own payback. Not enough to hurt him -- just a little sexual pain.

He looked at me, and I said, "Payback." I looked into his eyes and smiled while my right hand continued to stroke his cock. We kissed again, my hand never letting up on his dick.

"I love your cock baby," I said when we broke our kiss.

He looked back at me and said, "Show me."

Again, I went down on his cock. I couldn't believe how hard the tip of his dick was. It was almost purple as my lips enveloped it, and my mouth swallowed every inch of him. Pushing myself, I took him deep again. It was getting easier to hold his cock in my throat now, and I was determined to do so as long as I could. I tried to run my tongue over the shaft of his cock as I held every inch of him in me.

This caused him to flinch, and I smiled inwardly, knowing I had done something right. Then I felt it. There was a vibration in his cock, and I knew he was getting ready to cum.

"Oh fuck, mom," he said.

Almost immediately, I felt the first volleys of sperm strike my throat. I started pulling back, and he let me, but I kept his cock in my mouth, taking the first few ropes of cum completely down my throat. I pulled my mouth off his dick, and he started stroking it. His spurting cock kept shooting huge gobs of sperm onto my face.

Jason's orgasm seemed to last forever as jets of cum continued to spurt from his cock. I opened my mouth again and caught more of his cum in my throat. I greedily swallowed all of it.

Finally, the flow of his sperm subsided, but he kept stroking to empty his engorged dick of every last drop of his cum. I licked the sensitive tip, causing him to shake with pleasure as I ate the last few drops of cum from his spent cock. I looked up at my son as I milked one more drop of cum from his cock and smiled as I swallowed it. He stroked my hair as I finished with his cock.

I sat up on the seat and breathed deeply. I licked my lips in satisfaction, feeling the remnants of cum in mouth. Glancing down, I noticed that my shirt was covered in cum and saliva. Thank goodness it was a white shirt, but if anybody looked closely, there might be questions. I pulled out my compact and inspected my face.

Sure enough, there were drops of sperm all over my pretty face. I smiled, thinking about how much of a slut I had become as I reached up with my hand and brought as much of the cum into my mouth as I could.

"Oh, shit that's so fucking hot," I heard Jason say beside me.

I looked over, and he was starting to stroke his cock. Amazingly, it was beginning to rise again. The virility of the young never ceased to amaze me. Just as I was about to reach over and help him, I heard the volume on the radio go down, and my husband's voice called back to us.

"Hey, everyone. Gonna stop for a few. I need to hit the head and stretch my legs."

"Fuck," I said under my breath. "Okay, honey, thanks."

I immediately pulled a couple of wet naps from my purse and tried to wipe as much of my son's sperm from my face as I could while Jason begrudgingly pulled up his pants and put his wonderful cock away. I tried to wipe my shirt off as best I could, but it was still very wet from saliva and cum.

I would have to change at the gas station.

We soon pulled into the gas station, and I hurriedly exited the car for the bathroom. I had grabbed a dress from my suitcase before we stopped. Standing in front of the mirror, I looked at myself in the mirror and smiled then I stripped out of my clothes completely. I went all the way down to my bare ass.

I turned on the water and washed my face and torso of the dried cum. Next, I put the dress on without my bra and panties. I was shaking a little bit with anticipation. Yesterday, everything that had happened was spontaneous. Even the events of the last few hours with Jason today could be considered impulsive, but as I put my dress on without my underwear, I quivered knowing that I was now planning this.

I knew that I was going to fuck my son again and I didn't care about the potential consequences. I realized at that moment I had completely crossed every line. I had become one of those people you read about on the internet. I was like the teachers who have sex with their student, the ones about whom people think, "How could someone be so careless? Didn't they know the dangers?"

I understood them now.

I knew the dangers of my actions, and I was consciously choosing to ignore them and to act on my impulses anyway. I was actively planning on committing incest again. These thoughts kept my body shaking and my pussy dripping as I changed into my dress. The first time had been spontaneous, but this time I was planning it.

I had gone from a normal wife and mother of two to a complete and total slut who didn't care about the costs of her actions. I knew it was crazy to think about having sex with my son in the back of a moving car with my husband and daughter only feet away, but the craziness made it even more erotic.

It was completely nuts, and I knew it, but a part of me didn't care. I also knew that maybe this chance wasn't going to come again, and I was willing to risk everything for my passion. I was scheming to not only cheating on my husband with his son but to do it with him only feet away from me. I gave myself one last glance in the mirror and smiled, knowing exactly what I was going to do next.

I came out the bathroom and went towards the car.

Bill said to me, "Why did you change your clothes again?"

"I just wasn't comfortable before," I said. "The back of the car gets a little stuffy, and this dress lets me breathe better."

I tried to hurry back into the car to escape his questions. He looked at me, confused, but he didn't ask any more questions.

I got back in and sat down on the seat. The smell of pussy and cum was becoming very pungent in the backseat after the last few days. I laughed inwardly, thinking that it was only just beginning. Jason got in and moved to the back. He put his hand on my bare legs as he brushed past me and sat down. I smiled back at him, knowing it wouldn't be long before we were fucking again.

Soon we were underway again. I didn't waste any time. As soon as the car pulled back onto the highway, my tongue was down my son's throat again. We made out for a few minutes, our hands running up and down each other. I reached down and began to unbuckle his pants again while he started to unbutton my dress.

It didn't take long before we were both completely naked. Not caring that it was early afternoon and that anybody could see us through the windows, we kept kissing and caressing each other's naked bodies. I hoped we had all afternoon to play and I wanted to make each second count.

Jason began by kissing down my neck to my tits. He kneaded each of my breasts and took both nipples into his mouth. My nipples began to harden, even though it was quite warm in the backseat.

"Oh, fuck mom," Jason said. "You have fantastic tits." He played with each one of my voluptuous breasts. His hands continuing down my body, he pushed me back against the seat as he kissed my flat stomach and finally arrived at my pussy. The tips of my bare feet were now above the top of the seat.

He took his time with me, slowly working his way around my dripping wet cunt. Jason used both his tongue and fingers to gently massage my labia.

I marveled at how good my son was at licking pussy. Most men just get down there and shove their fingers inside without any buildup. Jason was different. He worked slowly, making sure I was ready before he began to finger me.

Over the next few minutes, he gradually increased his rhythm, and I was soon heading toward my first orgasm of the day. As I moaned, he picked up his speed his tongue and fingers working in unison.

"Oh, shit, honey I'm cumming," I warned him.

He moved his face back a few inches, but his fingers kept working my cunt. Then I felt my orgasm hit. My whole body quivered as I came and I felt the release of squirt in my pussy. I cried out louder than I wanted to as I felt the intense pleasure of my cum. I barely heard the radio go up again in the front as my body settled down from its climax and Bill never called back to see what was wrong.

After I finally settled I looked down at my son, who was smiling. I realized he had been hit with some of my squirt. His rippled chest was glistening as he looked across my naked body at me.

"You ready to go again?" he asked.

I motioned for him to come forward and soon we were making out again. While we did, he worked his fingers inside of my pussy again. Again, he worked his way down my sweaty body until he got to my pussy. Soon Jason was licking, sucking and fingering my cunt. I marveled at how good he was. Most guys his age had no idea how to get a woman off with their mouth. I couldn't take it anymore, and I grabbed his hair. "Fuck me again."

Jason looked up from my cunt, his chin glistening with pussy juice and smiled. He stopped licking my cunt and rose onto the seat. He placed both of his bare knees on the car seat and pulled me forward. Grabbing both of my ankles, he placed my bare feet on his shoulders and prepared to enter my pussy. I was again shaking, thinking about how dirty it was to have my son getting ready to fuck me again with my husband and daughter only a few feet away.

Our eyes locked as he brought his rock-hard cock towards my pussy. My eyes rolled back when I felt the huge tip of his cock begin to penetrate my waiting cunt. Slowly he pushed my lips open, allowing every inch of his dick inside. He gradually began to thrust. In and out the incredible feeling of his cock inside of me increased with the knowledge of the sweet taboo we were committing in the backseat of the car.

Eventually, he picked up speed, causing me to breathe harder and more loudly as I started to head for another orgasm. Then he slowed down and lowered my feet from his shoulder. He leaned forward and brought his lips to mine as he continued to thrust in and out of my cunt.

We stayed that way for a while. It was more like making love than fucking, and it felt unbelievable. We kissed and fucked, running our hands over each other's bare bodies. The squeaking sound of naked flesh on the leather seats unmistakable as we fucked. Soon we were both dripping sweat and breathing hard as my son kept his huge cock deep inside of my pussy. Jason leaned back a little as he continued to thrust into my wet cunt and grabbed one of my feet.

"I can't stop thinking about your perfect toes." He said as he began to lick and kiss my pretty feet.

"Mmm, you like what I did to you before did you?" It was sensual to watch him kiss and lick my feet while his cock kept pumping my pussy. Looking up our eyes met again, and I almost came once more. It was incredibly erotic, and I was even more turned on than before.

His tongue ran down every wrinkle on my foot as my toes curled with pleasure.

I had a sudden crazy thought that if Bill or Chloe looked back at that moment, they would see my son, his head above the seat and my toes deep in his mouth. The thought was both funny and sexy at the same time.

After a few minutes of him sucking on my toes, he pulled his cock out of my cunt and moved my feet down towards his cock. Slowly I skimmed my painted toes down his muscular chest and chiseled abs as I made my way towards his engorged cock. I knew exactly what he wanted and quickly obliged him. I began to slowly rub and caress his very wet cock with my feet.

We didn't need any lubrication this time as my pussy juices were coating his dick now. Jason threw his head back in ecstasy as I jerked him with my toes. My whole body tingled with excitement as I moved my feet back and forth on his cock. What was a few minutes ago erotic was now completely hard core?

Jason started to breathe a little faster, and I could sense that maybe he was getting ready to cum, but I didn't want that yet. I released his cock from my feet. He looked down at me pleadingly. I waited a minute for him to settle down then instructed him to put his dick back inside my pussy. He smiled and did as I told him. Within a few seconds, he was pounding me hard again.

Eventually, we switched positions as I wanted to keep his orgasm at bay for as long as I could. He climbed off the seat while I sat up. Then he laid his naked body down on the bench seat and gently stroked his cock while I climbed on top of him.

With my pussy dripping, I perched above him until he was in position. Then, slowly, as our eyes met, I lowered my cunt onto his cock, moaning with pleasure. I felt the entire 9 inches of my son penetrate my pussy. I looked down at him and smiled as he placed his hands on my sweaty thighs.

I began to play with my tits as I rode him. I looked out the window and realized anybody driving by would see a very naked woman playing with her tits in the backseat of the car. Thank god traffic was light, and the Expedition rode high. I also realized I was way above the seat, too. I looked towards the front of the car and froze.

My daughter was staring right at me. For a split second, I didn't know what to do. On the one hand, my son's cock fully penetrating my cunt was the best thing I had ever felt, but on the other hand, what the hell was I going to do now?

Then I noticed something. Chloe was topless. Part of the seat was blocking her and me, but I could tell that she too was not wearing a shirt or a bra. In fact, it seemed that she had her tits in her hands and she was licking her lips in the direction of my husband. Our eyes met, and we both looked at each other in shock. Then she gave me a wink and brought her finger up to her lips in a shushing motion.

I had a million questions in that second, but there was no time for answers. Either both of us were to reveal to each other what we had just seen, or we were to pretend that nothing had happened and we were to go on with our mutual debauchery. My son settled it for me.

He thrust his cock up inside of me. Immediately, I forgot about the last few seconds and pushed those thoughts away for now. There would be questions later to ask my daughter, but for now, if she could keep my little secret, I could keep hers. Besides at that moment, Jason's cock felt so good; I didn't care about anything other than cumming again.

I rode Jason for another 10 minutes or so, gradually increasing my speed as I neared another orgasm.

"Oh, my god," I said as I came all over him again. I felt the squirt escape my pussy once again. I fell over, onto Jason, as the orgasm racked my body. My knees were weak, and I could barely hold myself up with my hands as my orgasm made me shake and quiver.

Jason left me little time to settle down before he grabbed his cock and put it back inside of my literally dripping pussy.

"Holy fuck," I said, almost squealing as he began to pump me from the bottom.

My boy was in great shape, and he kept up his upward thrusting until I took over again. I rode him like a horse as he held onto my legs. Then it was my turn to lean down and kiss him as we fucked.

"Oh god, mom I love you," he said as we kissed.

I smiled and said, "Show me how much you love me. I want you to fuck me harder than you've ever fucked in your life but don't cum inside me okay?"

He looked up at me and smiled. "Okay but you need to be on all fours," he said.

I climbed off him, and we switched places. He waited as I got up on the seat, my head pointing towards the driver's side while my ass and bare feet were up on the seat facing the passenger side. I looked out the window, and I burst into laughter.

"What?" Jason said.

"Nothing," I said as I laughed. "I just can't believe we are doing this right here in the backseat while we are traveling at 60 mph. It's a little bit surreal that's all."

He smiled. "I agree." Then he added. "But it's hot as fucking hell isn't it. The feeling that we might get caught that somebody driving by could see us. It makes it so much more exciting. Oh yeah and plus you're the hottest fucking woman on the planet," he said.

I smiled. "I love you so fucking much baby. Now give it to me."

As I was saying this, I felt his huge tip begin to penetrate my dripping pussy again. He quickly began to thrust into me harder and harder at one point he pushed so hard that my head slammed up against the side of the car.

He had also completely bottomed out inside of my cunt. The feeling was mixed as I felt extreme lust and excitement but a little bit of pain as well. I had thought about giving him my ass, but now as I felt the pain, I was glad I hadn't besides that act would be something special and not for the backseat of a car.

"Ohhh!" I cried out in pain as it hit me. I saw stars for a few seconds. I was breathing heavy and leaning against the side of the car.

"Oh, shit mom are you okay?" he asked.

After a few seconds, I breathlessly said. "Yes." Then I added. "Now give it to me again, harder."

Jason smiled and quickly began to work his massive dick backward and forward, never truly escaping my pussy and slamming into me like never before. We had done this a little yesterday but not like this. This was pure animal on animal lust and passion.

"Harder," I said.

"Are you sure?" he asked.

"Oh, fuck yes," I almost screamed.

I could feel every nerve ending in my body tingling. This was a sensation I had never had before. Jason began to pick up his pace a little as he pushed his massive cock inside of me. My son thrusting back and forth, I felt things I had never felt before.

"Oh, holy fuck," I said as he began to fuck me harder.

Jason continued to fuck me, and I could feel an orgasm coming.

"Jesus Christ," I yelled out as he kept pounding me. I couldn't believe how intense this was. I felt my orgasm swiftly approaching, and within a minute I began to feel it. Jason had to reach down and hold my mouth as I was almost screaming in pleasure as he thrust into me.

I didn't even know I was too loud as I felt the most powerful orgasm I had ever felt crash through my body. Three times over the last two days I had thought that I had experienced the best orgasm ever and all three times I was proven wrong.

My body shook, and I braced my arms against the seat to keep from falling over as my body shook and quivered in pure pleasure. By the end, I was whimpering with gratification as I came down from my cum. I had no idea that anything in this world could feel so good. I still felt my son's huge cock inside me, and he soon began to pick up his pace again.

Jason continued to plow into me, his pace getting faster as he undoubtedly was heading for his own orgasm. The sound of skin smacking was palpable in the backseat as he pushed harder and harder into my cunt with his cock.

Finally, he said, "Mom, I'm cumming."

"I wanna feel it all over me!" I cried out.

He quickly pulled out of me. Within a few seconds, I felt his warm sperm strike my naked sweaty back. Rope after rope of cum struck me. The first few volleys hit me in the upper back. As he continued to send blast after blast of cum, I felt it strike my lower back, then, finally, all over my ass cheeks.

I swear he came more that time than in all the previous times we had been together. When it was finally all over, I glanced back and saw that I was literally covered in cum. Jason stood there completely spent breathing hard as he jerked his cock trying to squeeze every last drop of sperm onto my bare ass.

I looked up at him and smiled as I felt the sperm begin to roll down the side of my back and onto the seat below which was now a mess of fluids.

"Holy fucking shit," I said looking at my glistening back, I was absolutely covered in cum.

He smiled, finally catching his breath.

"Now what the hell am I going to do? I asked. "I've got sperm all over me, all over the seat and your father and sister are only 6 feet away from us."

He kissed me again and grabbed a hold of my tit from behind.

"I don't know mom, but we'll think of something."

I kissed him back and smiled as I reached back and grabbed his cock. "Do you think you can go again, big boy?"
