The two girls sat at Asuka's dining room table, sipping red wine that Misato had "accidentally" left behind at one point. Both were slightly tipsy, but not completely hammered. Under ordinary circumstances, they wouldn't believe it after the day they had. Never would either of them imagined they'd have sex with each other twice in one day. With Shinji as a girl, no less.
"You sure Misato left this wine here on 'accident'?" asked Shinji.
"Who knows?" replied Asuka, sipping her wine, "Ironically, she leaves a lot of leftover alcohol after her parties."
Shinji downed her last sip before pouring herself another glass.
"So are we...official?" she asked.
"Officially what?" asked Asuka, pouring another glass herself.
"Y'know...an item," Shinji replied, "I mean, we've had sex twice today alone. That has to mean something, right?"
"...maybe it's the wine talking, but I kinda just enjoyed the sex," Asuka replied, "I mean, you've only been a girl for what, one day?"
"But we've known each other much longer," Shinji said.
"Shinji, please," Asuka said, "I've preferred girls since I knew I had a penis. Please just let me have this while it lasts."
Shinji watched as Asuka downed another glass of wine. That must have been why she gave her those pills in the first place. As a boy, Shinji wouldn't have had a real chance with her. But as a girl, Asuka craved her. At that point, she knew that was how it would have to be to keep Asuka to herself.
Without saying a word, Asuka stood up and slightly wobbled over to Shinji, kissing her as their boobs pressed firmly against each other. Taking Shinji's hands into her own, Asuka pulled Shinji up as she guided her towards her bedroom. Not even bothering to remove the sheets, she put Shinji on the bottom and herself on the top, letting her breasts hang over Shinji's face.
From the bottom, Shinji watched as Asuka's breasts swerved side by side, each bouncing off the other, even through the thin fabric of her sundress. She could see that her nipples were already hard just by the fact that she could see them through the yellow of her dress. Shinji, having grown much braver in the single day she became like this, pulled the dress down enough to expose Asuka's breasts, now dangling in full glory over her face. Asuka moaned as Shinji bit the tip of her nipples, pulling them closer as her mouth absorbed the rest of the nipples.
Though tough to manage, Asuka had already gotten Shinji's pants down, as well as her underwear. Asuka did not have to go through that herself. One obvious reason was she was wearing a sundress. But the other factor was that, because it was just the two of them, Asuka never bothered to put panties on. In other words, once her legs were spread, her penis went inside Shinji and was grinding it into her. Both had already gotten wet while Shinji sucked on Asuka's breasts, but that intensified as their legs mashed against each other while fucking.
Asuka's hands were on Shinji's breasts, squeezing them hard enough to the point where the faintest trace of milk could be squeezed out from her nipples. She had been developing very quickly. Shinji had no such luck getting milk from Asuka's breasts, but that didn't stop her from sucking it like a pacifier. Even with Asuka's breasts in her mouth, Shinji moaned as Asuka consistently pushed her hands into her breasts. All while their juices flowed down their legs as Shinji's lower half was consistently fucked.
"Shinji, I'm..."
"Mmmhmmm!"
Shinji's muffled reply was quickly met with both girls cumming on each other, both still playing with the others' breasts. Asuka cried out as Shinji's teeth pulled on her nipple, stretching her left breast out. Once Asuka's penis left Shinji's vagina, she opened her mouth, letting Asuka's breasts drop as she herself moaned aloud in pleasure.
Shinji stretched her arms out, sweaty and panting heavily. Having been aroused and cumming three times in one day proved to be an exhausting task. Asuka had sunk her face into the sheets of her bed, pressing her wet breasts against it. Steadily breathing, Asuka already passed out from exhaustion, not even being able to tell Shinji how much she really appreciated her.
"I guess I can tell her when she wakes up," Shinji said.
Sighing in contentment at what they had, Shinji wrapped herself around Asuka's body and fell into a peaceful slumber.
