Glitched Isekai

Sam summoned the remaining girls from the Xenomorph nest

Raven (Mystique), Yuriko (Lady Deathstrike), Jennifer Check, Rey and Harley Quinn were instantly brought into the Nexus and they were still in the mist of what they were going through. 

Yuriko was bloody and in the midst of battling xenomorphs with her claws fully drawn, even with a large hole in her chest.

"Calm down Yuriko! It's me! You're safe now!" Sam said approaching her and then hugging her as she collapsed in his arms. 

Harley and Rey had facehuggers in their faces and the Kryptonians Kara, Samantha and Linda removed them and destroyed the facehuggers with their heat vision. 

Jennifer was screaming as her chest was pulsating, her face was all warped in pain as her demonic side screamed. Just then, the monster in her chest exploded out as she screamed in pain.

But instead of passing out, she grabbed the wormlike xenomorph with her hands and opened her mouth extra wide and chomped down on the creature's head. The acid blood sprayed everywhere, melting her flesh and bones, but she continued biting the worm's head off, disregarding that her beautiful face and body was melting before collapsing after ripping it's head completely off its body. 

"Jennifer!" Sam yelled, unable to approach her body because of all the acid everywhere.

Raven held Sam back, as he was about to rush at Jennifer regardless to heal her. 

"I'll put her out of her misery" Hancock said coldly as she used a Gantz sword to chop off Jennifer's head. 

Moments later, Jennifer appeared naked, fully whole in another part of the Nexus. She glared at Hancock but didn't say anything. 

Sam was reluctant to kill any of his familiars, although this was something he regularly did initially. This was because in the mind link, he discovered that every death did effect every one of them mentally. It didn't break them, but they felt the very real pain of dying. 

He just realized that Raven was hugging him from behind and asked "Raven... are you ok?" surprised that she wasn't affected by the xenomorphs. 

"I can shapeshift so that the alien is not incubated in my body and secretly expelled the alien fetus out of me before it hatched" she smiled

"That... thats good then" Sam said and looked at the xenomorph nest from Mary's eyes, many miles above the nest. 

"What do we do? They're clearly more of a threat than we thought" Natasha asked. 

"I've held this back. There is one person who I have yet to summon. I... I actually fear her. She's my ultimate weapon, my final solution. But I worry I cannot control her in case she loses control" Sam answered. 

"Who is it?" Ororo (Storm) asked. 

Suddenly, a xenomorph claw exited Sam's chest from the front, much to the surprise of all the familiars around them. 

Sam vomitted blood as he turned around only to see Raven morph into a xenomorph!

"Shit! A xenomorph with Raven's powers!" Diana (Wonder Woman) yelled as she slashed at the creature with a Gantz sword. 

Meanwhile, Hermione and Alex were helping Sam with healing spells as his chest was hemorrhaging blood. 

The xenomorph engaged several of the familiars in the Nexus, able to shapeshift to many weird and deadly shapes. 

He claws instantly killed Laurel (Black Canary) and Thea (Speedy) chopping their heads off and barely missed Elektra whose arm got chopped off. 

Kara and Carol tried to attack it, but it managed to shapeshift it's way out of their attacks and managed to kill Wynona Earp. 

"I got the real Raven!" Quorra yelled while the chaos was all around.

Sam turned and look aghast at the condition of Raven's body. Her whole abdomen seemed like it had been used again and again as there were so many holes on her abdomen.

"We're wasting time!" Hancock said, grabbing the xenomorph with both hands and ripping it apart.

Acid blood covered her, but all it did was short out and melt her Gantz suit.

Sam looked at her and she nodded saying "Do it, Your nuke option. Your final solution. Kill the bastards!" she said

Sam nodded and laid on the nearby bed as the other girls surrounded him, wondering who it could be.

Even now, Sam was uncomfortable having sex with an ever growing audience of his lovers.

Especially when so many beautiful women were staring at his flaccid cock with expectations, he was suffering from performance anxiety.

They literally had the faces of the most beautiful actresses in Hollywood and in fact were even more beautiful due to Sam creating them to ideals in his imagination, without the physical flaws of the real people they were based on.

Watching him hopelessly masturbate to try to get it up, Mindy, who was his first familiar reached out her hand to help him and her mouth opened to give him some stimulation. 

"Hey, you've had him the most. Let us new girls try" Jessica Jones said, being one of his latest familiars who were still new to him. 

Chun Li protested. "Just because we were earlier, doesn't mean we have had it as many times as you think" as she too joined the fray. 

Suddenly, more and more of them were wanting to get in on the action.

Sam could not choose, so he lay down and closed his eyes. 

He felt something approaching his face and he stuck out his tongue as someone sat on his face and he eagerly ate her out. 

"Hey! No fair" he heard Alex's voice. But not caring, he kept his eyes closed as he ate whoever it was

At the same time, he felt multiple tongues lick him, making him incredibly hard. Many mouths took turns sucking him and he felt like he would explode in pleasure. 

However, a mouth started emerging from his groin "swallowing" his dick instead. The many mouths kissed the new mouth, fully knowing what would be happening next. 

After a while, they pulled back letting the new girl emerge from Samsara's cock. 

Sam opened his eyes as the girl on his face started grabbing his head and cumming on him. moaning loudly. He was surprised to see Kate Kane aka Batwoman who was a lesbian.

She smiled at him and said "Not bad for a cis man. You... may very well be a man I want to fuck often" she smiled. 

"Take a number" someone said disgruntedly from behind her. 

"It's starting" Alex's voice could be heard in an excited tone.  

As a naked body emerged from him, her red hair appeared and several of the familiars gasped.

In a way, it was kind of obvious who it would be.

She should have been one of his earliest familiars due to her being so well known.

But his mention of being afraid of her losing control also made sense.

Several of the familiars who knew her subconsciously took a step back. 

Luckily, Sam no longer felt pain when he summoned new familiars, only intense pleasure. 

But this didn't stop him from feeling worried and fearful looking at her. 

"Hi lover" she said, her naked body hugging him as they were attached at the groin.
