Some sisterly time

Jane's body begins to shake again, seizing up briefly as control was wrested from the motherly spirit within it. Your fiancée was not the one to end up with control, however. Her eyes dropped, eyeing the exposed breasts, and her hands immediately rose to grasp and caress the chest before you. Jane moaned as she did, seemingly forgetting about you once her hands rested on the massive globes of flesh.

"Hey, uh..." you started, but were quickly interrupted when Jane suddenly sat down on your lap.

Without a word, your girlfriend's hands reached down to your own, gliding them up her body to bring them to rest on her breasts. "Be a little rough with me, yeah? I want to know what it's like," she said, her breath quickening when she did. "It's Molly, by the way. When mom took the tits out, I had to get in control so I could feel these things totally unobstructed."

What could you do but comply? It was simultaneously familiar and foreign, having your hands on Jane's body, and yet the way she moved and spoke made it feel truly like somebody else. Molly sounded very similar in her normal body, and looked fairly close to her sister, except for the endowments that her sister inherited. So long as she was within this body, it seemed there was no reason to be jealous--but she absolutely needed to make sure to enjoy what time she had in it! Molly wriggled her stolen body on your lap lightly, as you decide to grip the breasts firmly, to knead and jiggle them. Molly moaned through her sister's lips as you toyed with her body.

"I really think this could've been us," she said, quietly. "Like, maybe there's a lot less to squeeze, but I'd wanted to be on this lap since I first met you. If I didn't introduce you to Jane, maybe I would've had that chance... but now, look! You still have her body right at your fingertips. And you and me, we click! Even if mom is obsessed with getting a grandkid, I wouldn't put that pressure on you. Instead..."

Jane turns around to straddle you, as she grins, slowly moving her shoulders back and forth to rock those glorious breasts in front of your face. "I don't really want kids so I'm not going to be a party to that. When you want to go at it like that, call mom up for sure and she'll take you for a ride with this body. But me, I'll do anything you want with these tits, with you or to you or... at you? I don't know. I'm sure we could get creative."

Molly reaches down to lift up the breasts again with Jane's hands, almost hypnotically rocking them in front of you. Her nipples stood at attention, firm and ready to be licked, but Molly wasn't ready to decide whether that was the activity she wanted to do with the body yet or not. She reached down with a hand, feeling your hardness right under her lap, which you had tried to make it seem like it wasn't a big deal.

"Maybe a titfuck is what you need? Does Jane give you those? I bet she doesn't, does she? Well, when I'm in charge of her, you can have them whenever you like. Maybe I won't even put on a bra and shirt when I'm in control of the body! I'll just be Topless Jane for you. Doesn't that sound fun?" She grins.

"Molly, she doesn't, but it's not like she needs to, or anything,,," The way you say the words made any impact fizzle. Clearly, you favored Jane's breasts and you were extremely aroused by the idea of having an all-access pass to them when Molly was in control. Just because your fiancée wouldn't use her breasts like that on you doesn't mean you didn't hope she might change her mind sometime, and now it turns out with Molly in there, you'll get your wish! Sort of. It's hard to call it cheating when it's all within the same body, but it felt like you kind of were as you went more and more along with Molly's plans.

With a devilish grin, she stood up, swaying her large breasts back and forth. "So we got mom wanting to get you pregnant, I'll do anything with these jugs whenever you ask... oh, there's a lot of other ladies in here too, you know, who will probably show you an aspect of this body that you'd only ever dreamed about. I bet Jane isn't as diverse in the bedroom as she might claim, huh? Just talking to these other girls in here, you're gonna get every kind of girlfriend you ever wanted. And you're gonna get some creative ways to play with us... Mary will take it from behind with all the other kinky stuff she'll do, Denise will give you blowjobs you'll never forget... but also, Sam will give you that best-friend casual experience, while Jan will behave like your attentive girlfriend. Don't you see? You can customize your experience with all of us in here."

"And what about Jane?" you asked.

Molly shrugged. "If you want selfish, sure. She takes what she wants, when she wants it. Any time you thought you were getting what you wanted from her, it's probably because she was getting something she wanted in return. The rest of us won't be like that! So what is it you want, right here, and right now, from this body? These tits are ready to go, give the word. Or, someone else has something else on the menu for you?"

Given that breakfast was already going cold, it seemed like perhaps maybe it would be best to just take the initiative and choose what you want Jane's body to do for you. On one hand, it was selfish, but it also meant that they wouldn't be doing anything worse to her if you just cooperated...

And you absolutely wanted to cooperate now, try as you might to cast out thoughts about being the noble boyfriend. Not with what was being offered to you... the real Jane was going to have to wait.
