The large half-moon couch in the apartment living room was playing host to two reclining women, half a bowl of popcorn, and one argument. About sex.
"Rei, you may be a near-goddess both metaphorically to us and literally to physics, but even if Doctor Akagi cracks the code on you having children, you still won't be a 'virgin mother'. That's just silly."
Rei gave one of her tiny, smug little smiles. "I will have you know, Asuka, that I am still a virgin."
Asuka stared at her wife. "....ok, what? Rei, I know you are not a virgin, by very direct observation. Multiply not-a-virgin. In every possible way. By boy or girl."
"Simple, I still have my virginity." She paused. "Well, a virginity."
"You're going to need to explain that one, or I won't spank you for it."
Rei pretended to swoon. "So cruel! Well, if you insist, my beloved wife. Like this: You and Shinji know very well that Kaworu and I first had sex not long after we defeated SEELE, yes?"
"Very yes. You both walked around grinning like idiots for days. Which was really weird to see on your face back then."
"Well, considering Kaworu's own desires and interests, and the fact we were each other's only sexual partner back then, after he took my virginity... I took it back." Rei winked slyly.
Asuka's jaw dropped open for a moment. "Rei, did you... you... I mean, you-"
"She pegged me like a pinochle board," Kaworu said cheerily as he breezed through the room on his way to sneak a snack and a kiss from Shinji in the kitchen. "I was very interested, we were both horny, and so my darling avatar of Lilith put on a nice big strap-on, bent me over the bed, and pounded me like a bent nail. And oh gods, I saw stars. Unf! So we traded off back and forth for the rest of the night. Weekend. Whatever."
Rei smiled at him and continued. "So yes, he took my virginity, I took one back, ergo, I am still a virgin. QED."
"Rei, that is not how that works," Asuka complained, facepalming.
"Would you like to take my virginity, Asuka?" Rei said impishly. She stood up, turned around, and gave a tiny shimmy of her rear at her wife. She looked over her shoulder with a faint Rei-grin.
"Unfgrmblg..." Asuka said thoughtfully, biting her lip hard. Rei's ass was a work of art, and watching her husbands make it shake and bounce as they pounded Rei most nights had made her sometimes picture what doing that herself might be like...
Rei noticed Asuka's sudden wrestling match with temptation and growing depths of her Rei-sexuality. "I still have that same strap-on, so you can even do so with the same implement that took Kaworu's, thereby making you a double-virgin by the transitive property of banging," she offered teasingly.
"Rei, what you just said made less than zero sense. That's not even close to math. Or physics. Or-" Asuka suddenly stopped and gave Rei a calculating look. "And this was all one of your elaborate schemes to wind me up, drive me nuts with horniness, and get me to take you into the bedroom and make enthusiastic love to you in a way we haven't tried out yet?"
"Is it working?" Rei sat down in Asuka's lap and wiggled. "You are the only one of my spouses who has not yet done that, and I think it's only fair that youYEEEEK!"
Asuka had abruptly wrapped her arms around Rei's midsection, lifted Rei up off her lap, and somehow slung Rei over her shoulder as she stood up. "Shinji, Kaworu, Rei and I will be back in a bit! This bloody minx we married is doing it again!"
"Dinner's not for an hour or so. Have fun!" Shinji's voice replied from the kitchen, not even sticking his head in to look. "Kaworu's got no pants on again, might be two hours!"
"Help. Help. Oh noes," Rei deadpanned as she was carried off.
