Change you into a girl, with the same problem you gave her

The first thing you notice is your chest starting to balloon out in front of you, causing your shirt to tighten and rise up slightly. It doesn't take a genius to figure out what exactly is going on here.

"You're changing me into a girl?" you say, your voice already sounding higher and more feminine.

"Yup!" Erica says, "Oh man, I still can't believe this is happening."

"Yeah, me neither," you say, less excited about the prospect of becoming a woman than she is watching it. You feel your lips puff up ever so slightly, and your face restructuring itself to become more feminine. It doesn't hurt, but it certainly feels weird, especially when you put your slimming hand up to feel it happening under your fingers.

You breasts stop growing at what you guess are C-cups, and your t-shirt is now much tighter on your chest, allowing anyone looking at you to see that you are not wearing a bra of any kind. You squeeze your boobs experimentally.

"Whoa, they feel so real," you say to yourself, your voice now almost unrecognizable to you.

"Yeah, I'm not enough of a bitch to give you fake tits," she says with a shrug. Then pouts and asks, "Wait, can the Ruby even do that?"

"I think it can, but I haven't tested it out," you tell her, before squirming in your seat.

"What wrong?" she asks with a cheeky grin, "Feel something missing down there?"

So that's what was bugging you. You look down and see that the changes below had already completed themselves while you were marveling at your new bosom. Your hips were wider, and judging from the plushness beneath you you were certain that your ass had grown out too. But your crotch was suddenly feeling a whole lot emptier.

"Go on, take a look," Erica urges you, "I won't mind."

You stand up and pull the waistband of your sweatpants forward, looking down at your crotch. Sure enough, your penis was completely gone, replace with a completely bare slit. You can't help but notice that it looked flushed with arousal. Maybe this was turning you on more than you thought.

"This is so weird..." you say.

"You like?" Erica says, "I made sure you didn't have any pubic hair so you could see it clearly. Go ahead, give it a touch."

"Seriously?" you say, blushing hard, "Erica, what are you-"

"Oh, come on, you know you want to," she teases you, "It's not like I'm asking you to jill yourself off in front of me or anything. Just give it a quick feel."

Something about the way she was smiling at you told you that she had an ulterior motive for making you do so. Deciding that it would be better to get it over with, you stick your hand down your pants and brush your womanly fingers against your new cunt.

Immediately, you let in a sharp gasp of air as you felt entirely new sensations in your nether regions. It felt great, but damn were you sensitive. And wet. Yup, you were definitely aroused. Although... even you could tell something didn't feel right. Worried, you pull your hand back out, and see a familiar white goop sticking to your fingers.

"Oh, you didn't..." you say, looking over at your friend in realization.

"Like I told you before, turnabout is fair play," Erica replies smugly, "Let's see how much you like walking around with your pussy constantly dripping semen."

You take a moment to compose yourself, then say, "Okay... yeah, I guess that's fair. Um, how long are you going to keep me like this."

"Just for a little while," she says, "Until I think you learned your lesson. Now wash that shit off your hands. You still owe me a round of Mortal Kombat, and I don't want cum all over my controllers."

Her non-committal answer and the nonchalant way she brushed past the question worried you a bit, but things certainly could be worse. You give her a nod, then make your way into the bathroom.

When you finish washing your hands, you take a moment to check your new self out in the mirror. Surprisingly, you make a pretty hot woman. Erica didn't even change the length of your hair, though you notice that your eyes are a little wider and your lips are redder than you remember them being. You use your fingers to poke at your nipples, which were visibly erect under your shirt, then reach behind you and give your new ass a squeeze, feeling the soft flesh between your fingers.

Maybe this change isn't all bad, you think, giving yourself a quick spank and feeling your butt jiggle a little at the impact, There's at least one thing I need to do before Erica changes me back...

With a bit of difficulty, you pull off your shirt and drop it to the floor, exposing your new breasts to the open air for the first time. You jiggle your melons in front of the mirror, enjoying the sensation of playing with your own pair of breasts.

"Hey big boy," you say to the mirror, making kissy-faces at the woman reflected back at you, "You wanna fuck me? I'd fuck me... I'd fuck me so hard."

"What the hell are you doing in there?" you hear Erica shout from the other side of the door.

"N-Nothing!" you yell back, grabbing your shirt off the floor.

"Whatever it is, finish up," she responds, "The game's ready to go!"

You slip your shirt back on and pull it down, only now noticing that with your breasts taking up more room in the top, you now have a bit of your midriff showing. Noticing the wetness starting to grow in your crotch, you grab some toilet paper before you leave and stick it down your pants, wiping at your new vagina. Feeling more semen coming out even as you wipe away the mess already there, you realize the futility of getting rid of it all and decide to just stuff a bunch of toilet paper down the front of your underwear to try and soak it up as it comes out. You're not sure how long your improvised protection will last, but it'll at least give you some more time before your eternal cream-pie drenches your pants with cum. You just hope Erica won't leave you stuck like this for too long.

You wash your hands again, then give one last look in the mirror at your new face before heading towards the door.
