One Fit Sizes All - (100) 50 gems - Body changes to fit any worn clothing or costume

Kathryn has a hopeful look on her my face.

I glance at her clothes strewn across the bedroom floor. Wait, are you buying that to turn me into a woman?

Maybe? She hesitates. I mean, do you mind? You had such a good experience with your boobs already! She uses my left hand to underscore her point, causing us to throw my head back and arch my back in pleasure.

I said earlier that anything goes. I stand by that. I want to know what it's like. You can spend those 50 gems.

Oh Captain, you're the best! You won't regr--

Her thoughts cut out the moment she hits the Purchase button, and another confirmation dialog appears. I quickly hit Confirm.

--et it! Whoa, my brain lagged there for a second. Was there another confirmation thingy?

Yeah, apparently the succubi built in another failsafe so a Girl can't buy anything without the user's consent. It went through already.

Weird, I don't feel any different. Normally there's a tingle or something when you make a change.

Have you considered that you're currently rubbing your Magic Hands all over our boobs? How would you feel a slight tingle with that distraction going on?

Wait, I'm doing that? I thought that was you the whole time! Anyway I'm not stopping, it feels way too good!

Please, we're not getting anything done otherwise! I don't wait for a response and try to lift myself off the bed using both my hands. We're not fully coordinated, so it takes more effort than it should, but at least Kathryn cooperates once my feet touch the floor so I can actually stand up straight. We're still flailing my arms a bit trying to keep our balance.

Oh no, this is like playing QWOP! Can you just let me drive? I promise I won't grope us again!

I let go, feeling a bit of relief as Kathryn actually manages to get ourself together and walks to her dresser. She opens the second drawer from the bottom and takes out a pair of lacy black panties. Seeing them in person suddenly feels a lot different than talking about becoming a woman in the abstract. I swallow.

Kathryn senses my discomfort. Are you okay? We don't have to do this, you know?

I take a deep breath. It's fine. You trusted me a whole lot over the last few days with everything about this app, and everything turned out fine. The least I can do is trust you right now.

Kathryn smiles with my face. Okay then, hold tight! No, not that way, actually you know what, just relax! Relax, and everything will be fine!

She steps into the panties with one of my feet, then the other. As she slowly pulls them up my legs, a pleasant tingly warmth builds up in my calves and thighs. Finally they reach the top, where my dick is waiting for them. The black fabric gently envelops it, like an assassin smothering their mark with a silk pillow. I can feel it trying to get hard and sending arousal through my body, but at the same time shrinking and drawing in. The balls below it share a similar fate, being painlessly drawn inside my body and leaving an opening behind. I can feel it waiting to be filled. Not wanting to wait any longer, I take control of my right hand back from a surprised Kathryn and jam it in there, feeling it brush past the clitoral remains of my dick, stimulating it to new extremes, and settling between the lips of my new opening. I slip one finger inside--

Hello? Captain? Even inside my head, Kathryn's voice sounds breathy and aroused now. I know you're just experiencing what it's like to have a pussy for the first time, but don't you want to go all the way to a fully female body first? Trust me, it'll feel even better!

Not yet! I flop back down on the bed, continue stroking between my legs with my right hand, and put my left back to rubbing my tits. You've worked me up so much, I need release now!

I am now frantically trying out different modes of stimulation with my right hand and seeing what works, and before long I'm screaming out in my first female orgasm. It's the most intense thing I've ever experienced (though I suspect some magical succubus enhancement might also have something to do with that).

Kathryn and I lie on my bed panting in the afterglow. That was amazing.

Thank you Kathryn. I don't know if I would ever have experienced something like that if it weren't for you goading me into those shenanigans.

You're the best Captain I could ever hope for. Never change.

We continue to lie there for a while.

That being said... Are you ready to finish off your new look?
