Why not?

It almost seemed foolish, now, that you had spent so much effort finding clothes when you stripped out of them immediately. Sitting on your bed, legs spread and one hand going at your pussy, other playing with your tits, you moan and buck as you explore your new body. It has to be magic at play, right? Because if not you're not sure how any woman gets anything done. You've cum at least 5 times over the last...

Your eyes scan your bed until you see your phone, time displayed at the top. You've been at it for almost an hour already? How the hell? That means you need to wrap up. No way are you going to let Alex walk in and see you like this. Hell, even him just seeing the aftermath of a crazy masturbation session is too much for your mind to deal with.

Still, you think as you continue fingering yourself, you feel as ready to go as you were when you started. More, maybe. Nothing has quite... pushed you over the edge. It has all felt nice, but not explosive. Not definitive.

Eyes still locked on your phone, a thought enters your mind. You bite your lip, trying to **** the thought away. It's too far, it would be... just too far. You keep telling yourself that, even as you pick up the phone and navigate back to your texts with Alex. You open that photo, the first he sent, and stare at it. Knowing he was that hard for you, something clicks in you mind. You can feel your pussy quiver, know it's working for you. You navigate over to the video and watch him stroke himself, knowing it's because of you...

And as he cums, you do too. This has a more explosive quality to it. You cry out, back arching, and drop your phone back to the bed. Your vision darkens briefly, and you take what feels like forever to recover. Even when you have, you lie there and bask in the afterglow of the best orgasm you've ever had.

Then, you know you need to get cleaned up. You hurry into the bathroom and shower, then get dressed in your sister's clothes again. Just in time, too, as you hear a knock on the door.
