Oh, this one's easy

"You've probably got, what, two to three more hours of charge in that thing?" You tapped at your neck--well, Jan tapped at her neck, to an outside observer--and Jane nodded.

"Approximately, yes. That might fluctuate depending on the activities we engage in, but I can safely say anything we do could last for at least two hours before requiring a recharge. I have a lot of work to get done at the mansion later anyway, but I'll happily test out anything you'd like with your fiancée's body. Perhaps there are things you enjoy that she does not? At least while I'm in control, she will think otherwise when she looks back on what we did, and rationalize why she did them."

You grinned at that idea, tucking that little note in the back of your mind for later. "For now, I think getting acclimated to my new form is enough, before I figure out how to wake Jan up again." It was delightful hearing Jan's voice say your words! You didn't speak like the polite girl who does yoga and helps out at a farmer's market stall. And at the moment, Jane sounded entirely different as well, talking more like a professor than your girlfriend. Seeing her act all 'professional' with those glasses on excited you further. This really did start to sound like a good deal, where even after you're done being a ghost, you might end up with Emilia joining in as a kind of pseudo-girlfriend long term! Two-in-one seemed nice, especially if Emilia was offering to make Jane do all kinds of things for you...

You stepped forward, and started to unbutton Jane's blouse. She certainly didn't mind, offering you a smile and keeping her arms out of your way. It was rather nice having these nimble fingers of Jan's at your command. Truth be told, even though you loved being in Jane's body to play with some sizable curves, Jan's frame being less curvaceous and having much smaller breasts meant it was easier for you to focus on your puppeteered girlfriend, who started to slip out of the blouse, sticking out her chest in the process in your direction.

"Who knows, I might actually be quite beneficial to you over time, John. If she's wearing the collar and you get into a fight? I can activate it and change the mood. Or if you need her to make particular decisions, for example if there was something about the wedding, from the venue to the vows. Oh, wouldn't that be fun, if Jane wasn't even in control during her own ceremony." Jane smirked, reaching back to unclip the bra, letting the breasts bound out of their confines once more. "Ah, such a lovely body. I'm truly envious of your fiancée, John. If I can determine that it's safe for me to use the Ghost Machine, she might become my primary target for a while, since I wouldn't have to worry about batteries for the long term, and could even share control with her."

You didn't say anything, you just decided to step up closer to Jane and reach out to grab at the chest for a moment. You've experienced Jane's body in three different ways, through your own form, Jane herself, and now Jan's body was giving you a new perspective with her smaller hands, making these breasts seem even more sizable! Jane moaned lightly, rolling her shoulders back as she enjoyed the attention. But idle play with the breasts wasn't the only thing you were interested in, as you looked at your girlfriend's soft lips.

"I know she's not into women, does all this neural harness stuff change her perceptions on attraction the same way I did when I was in her?"

Jane nodded. "She likes what I like, and she will try to rationalize it when she's conscious again. And I like what you are about to do, John."

You couldn't help it much longer, indulging both Emilia's and your desires simultaneously as you leaned in for a deep, drawn out kiss! Your hands left her breasts to wrap around her back and face, holding her steady as the soft lips of two women felt so wonderful as they danced together. You could really get used to being in Jan's body, even if you were missing a few vital family-making components that you intended to put to use after marriage...

It was Jane's turn to take initiative, as she started to push against you, driving you backwards to the couch. You tumbled down, giggling--you're a giggler in Jan, apparently--as you stretched your arms out along the back of the couch. Jane stood up again, making a bit of a sexy pose as she peered down at you. Knowing it was Emilia in charge of your girlfriend was a strange but exciting feeling. Knowing there was nothing Jane could do to stop Emilia since her mind was rationalizing everything anyway, you realized just how helpless your girlfriend had become! Between you and Emilia, she might never have a moment of her own freedom for the next week until your stint as a ghost ended, depending on if you keep spending time in Jan or not.

Jane started to shake her hips back and forth, turning around to show you her ass as she peeled herself out of the jeans that encased her lower body. "I'd never be able to do anything like this in my own body. I... don't have much practice, so please don't judge me too harshly. Not that it takes much effort to make this form behave sensually..." Soon, the panties were all that remained, which didn't last long either. Jane slipped right out of them, before climbing atop you, your controlled girlfriend staring at you with an intense gaze through those neural harness glasses.

Jane's hands made quick work of your own shirt, removing your tank top and yoga pants swiftly until you were equally underdressed. She climbed back atop you, pressing her warm body to yours, feeling her trembling in anticipation at using your fiancée's body for her own purposes. Once again, her lips locked to yours, but this time, with her whole body on you, the pleasure was magnified so much from all this attention! Or, maybe it was that Jan wasn't getting much attention herself... You bucked and squirmed under Jane's body in the kiss, feeling the larger set of breasts resting atop you, and more importantly, feeling Jane's crotch grinding against yours. That was new! You grabbed her hips, applying pressure back, as both pussies rubbed against one another, trying to find the best angle to pleasure one another.

You felt a finger sliding around your slit, and you bucked back in response once something began to push inside you! You were breathing fast, Jan really hadn't had this kind of pleasure on her own in a while, you could tell, as her body was rapidly responding to the lovely woman and her devious grin atop you. "What do you think, John? When I'm in control, am I girlfriend material as well? I mean, I certainly have no reservations doing anything and everything with another body..." It almost sounded like Emilia was teasing the idea of simply overriding Jane's life when she talked like that! Understandable, given her various ailments in her normal self, but...

...but... you couldn't think straight. You couldn't think at all! Jane's hands in your pussy, teasing your clit, had you gasping for air. Jane sat up and adjusted herself so she was in your lap, reaching down to play with your slit still, pulling your head forward to rest against the lovely breasts under Emilia's command. Like with Yvette, you began to lick and suckle, focusing on the chest while a burning continued to develop between your legs...

You almost screamed as you came from all this stimulation, from the idea that your girlfriend was controlled into bringing you to orgasm--and from Jan apparently bottling up her emotions for so much that they were so easy to release! And so powerful, too... this orgasm really rocked your body hard, compared to what you had while within Jane before. You had to bury your face in a pillow to not disturb all the adjacent apartments..!

Jane simply smiled down at you. "I think I've done quite well with her body, all things considered."

Part of you wanted to just bask in these sensations you were experiencing as Jan. But another part of you wanted to repay Emilia for what she was making Jane do for you... perhaps you should show her the pleasures her own body is capable of--even if that encourages her to control Jane more often!
