Story: Rei Swarm

This was the best game that she'd ever heard of: Moulding a boy's dick into a bitch-breaker! The rules were simple: You win when the boy breaks his first bitch. As such, this particular Rei was all set to play. She'd pinned down Shinji onto the floor, straddling his waist and rubbing her hands all over his chest. Feeling his flesh, intermingling it with hers. Improving it. Kneading it like clay. Sculpting him from a reed into a bronze god.

"Uh, Rei? Wh-what do you mean by 'bitch breaker'?"

“An absolute alpha, the sort of man who can take the most prudish woman and make her hump his cock like a bitch in heat within five minutes.”

"Oh," Shinji said. There was a beat of near silence, only punctuated by the sound of her hips thumping against his. "I don't think I want to be a bitch breaker."

"Don't knock it till you break a bi~itch," Rei said. She leaned in and kissed him, incidentally interfacing with his mind so she could see what he was thinking. Which amounted to 'Gosh Rei's sister is weird. Is she really okay with us having sex like this?'

Which was so adorably innocent and naive that it made her cum right there and then. All over his non-bitch breaker bitch! Ah, now there's where we should start. In order to be a bitch breaker you had to have the right tools for the work. They say that a bad carpenter blames his tools, but Rei knew better. She knew full well that if you locked a carpenter in a cell full of sawdust, they couldn't build you a table no matter how good they were.

So first order of the day, make sure Shinji's dick was nice and big and fat so it could satisfy absolutely any pussy it was stuffed inside of. Of course he would need the stamina to keep going to actually make use of such a monster cock, but that was not nearly as hard as one would expect. Being able to remold the human body in almost any way imaginable had quite a few advantages after all. So many little inefficiencies that could be gotten rid of for example. By the end of this, Shinji would be able to go on a sex marathon with nothing but the occasional sip of water!

"I'm still not sure about this!" the boy protested.

"Really?" Rei asked. "But you'll have so much fu~un breaking bitches. Imagine what this thing will do to Asuka."

Well. That got him cumming in a hurry. Look at him, so cute with his eyes rolling up into his head while his hands grip onto her hips and his own hips thrust up and - ahhhh, how nice this is being filled up with his semen! Misato would be so proud of him for letting out so much!

Step two. While he was busy climaxing she'd put a little bit of knowledge into his head. While having the right tool for the job would be extremely helpful for playing around, it was also vital that he know how to use it. So Rei put that knowledge right into his head. An in depth understanding of the human nervous system, so that he could comprehend quickly and easily what made a girl feel goo~ood!

That is something worth remembering, after all. There's no 'one size fits all' when it comes to sexual satisfaction. Everybody is different, more's the pity. What feels bad for one person will feel good for another. Which is why Rei instead focused on understanding 'how' and 'why' to make someone feel good, rather than only one or the other. Of course it was quite likely that he would just end up working on auto-pilot unless thinking things through, but that was simply how these things worked. A musician doesn’t think ‘I need to play this note, then this one and then this one’ and so on, they just play it after repeating things so long they do it by instinct.

"Wh-what the hell is this?!"

Ah how helpful! A volunteer has arrived. It looked like one of the research team had come a-wandering down the corridor.

"He~ey!" Rei said, rising from Shinji's dick to wave at the gawking woman. "So, didja miss what's going on or something?"

"C-Coffee break," the woman said. "What's going on around here?"

"Oh, I'm training Shinji so that he can reduce women to a puddle of mindless cumming nymphos with casual ease."

"Uh, I'd really rather not do that!" Shinji protested.

"Aw, come on! Give it a try! I am sure you will have lots of fun turning Asuka, Rei and Ritsuko into moaning sluts." The dummy plug said enthusiastically. "Oh darn, she's running away. Alley oop!"

Rei dove headfirst right into Shinji's chest and merged with him. This was a bit of a cheat, of course. Still! There were no rules in this ga~ame. She could always come up with some later if she felt like playing fair.

The result? Fantastic. This was what she'd been aiming for earlier on while trying to sculpt his body, but she didn't quite have enough musclemass to pull it off. Before: A spineless reed with the muscle mass of an upright broom. After: A walking tree trunk with rippling biceps, legs like tree trunks and a lean set of abs that you could grate cheese on. Which sounded like a fun thing to try out later on, but for now -

"He~ey!" Shinji said, easily keeping pace with the retreating test subject on his newly powerful legs. "Where you go~oing?"

Cue the test subject being held up against the wall. Ah, ah. Now now. In case you thought the dummy plug was gonna do something gross here, no no. She wasn't going to force herself on this woman. Perish the thought!

After all, it would only make things tricky if Shinji’s first broken bitch was unwilling. Instead, she could just tweak a little thing here and a little thing there. For example, why not increase her sensitivity a couple times, set her sex hormone production into overdrive and rewire her brain to get off of Shinji’s smell? Just a few little things to make her more willing to work with her in training this cutie into the bitch breaker he should be!

"So, how do you feel about helping out now?"

"Guuhhhhhhhh!"

"Perfect! Now Shinji, I've kept you conscious so you can see what's going on. Pay attention as I satisfy this woman beyond her wildest -"

Huh. That's weird. She looked down at Shinji's massive meaty member. It was as flaccid as a damp noodle. That was strange. The dummy plug tried to will it into hardness. All she managed was making it flop forward like a dying flounder.

“Huh, that is odd, I didn’t notice any health problems when I was giving you these upgrades.” The clone noted, tilting Shinji’s head and chewing on his lower lip. Well, this was quite the problem, while she could satisfy the woman without a dick, it would be defeating the entire purpose of this exercise.

"I'm really sorry about this," Shinji said. "Rei's sister is pretty rambunctious. And... also apparently able to merge with people?"

"Sex me..." the test subject moaned, humping helplessly against Shinji. "Sex me right now!"

Oops may have gone a bit overboard with her. Well, let's see. While she was in here maybe she could work out what Shinji's issue was? There really was nothing remotely physically wrong here. He should be able to pierce steel with this weapon. Or at least break any chastity belt, even if it was made of metal.

And he was certainly able to get hard for her earlier on. So why - Aha! She found the answer in his head. It was a psychological problem. This boy was only attracted in that way to Asuka and Rei! And... a little to Misato, but mostly those two.

Well that was simply unacceptable, what sort of bitch breaker could only go for the bitchy tsundere and hyper introverted kuudere? There's a whole spectrum in between, you know! So many bitches to break, so little time? Easy fix! Copy her own sex drive into him, and that should do the job.

"Um... Rei's sister?" Shinji asked.

She stuck her head out of his shoulder and looked up at him. Ah, such a cute spineless boy he was, he'd make a fine stud by the time she was done.

"Ye~es?"

"I'm really sorry about this."

Then he grabbed her head, pulled her out of his body and began to fuck her up against the test subject, who was leaning up against the wall.

"Sorry," he said while pounding her pussy with his giant dick, though he was still using only just enough pressure to maximise the pleasure. "I'm really sorry about this. I don't seem to be able to help myself. Sorry, sorry, sorry..."

Ah. Well then. It seemed as though even with the absolute perfect peak of sexual prowess at his fingertips, Shinji Ikari was still a weenie deep down where it counted. There was something reassuring about that.

1. Asuka continues her recruitment of Reis.
2. Shinji tries and fails to handle his newfound arousal.
3. Asuka encounters Shinji fucking the dummy plug in the middle of the corridor.
4. Meanwhile, Ritsuko is interrogating Aoba as to what the heck happened.
5. Something else
