Before you can play, you get a call from your friend and crush, Jill. She asks you to come with her to the arcade, and a little bit later, you are walking through the park on the way to the arcade with Jill, talking to her while doing so. She never really had the perfect body, but you still like her more than you care to tell her, and she does have the best body in your classes.
You are speaking to her, and think of her breasts. A usual thought, but you are wondering more about how she keeps them in place without moving due to their size, which is unusual. You suddenly gets a strange urge, and want her body to be yours.
"Are you listening to me, Anthony?" She asks, seeing as you appear to have zoned out. You don't have time to answer as you feel yourself shrink, form into a fluid, and go inside her. You black out, but when you come to, your body feels wierd. You feel off balance, with a weight on your chest, a breeze between your legs, something around your neck, and an emptiness where your penis should be. You look down to see breasts covered by a blue shirt, a dark blue skirt that can easily be mistaken for black with how dark it is, a blue purse, and blue sneakers.
"Wha-" You begin, before your hands go to your mouth, as that wasn't your voice, in fact, it sounds like Jill's. You then notice that your arms are more slender. By this time, you have realized what has happened, but you just can't believe it, as it shouldn't be possible. You turn around and try to run back to Jill's house to find a mirror. You trip, however, because of being off balance, and skin your knee. You feel pain for a moment, before your knee suddenly heals. You are in shock by that. You get up, and slowly walk to Jill's house. You have a hard time adjusting, but you eventually get the hang of it, and eventually, you can walk without problem in this female body, but you still can't run. You arrive at Jill's house, search for her key in her purse where she put it, then pull it out.
You then unlock the door and go inside. You go to a mirror, and look in, finding what you've been suspecting, you are now in Jill's body! You try to come out of her body, but some of you remains in her. However, that's how you wanted it.
You have been wondering something.... You make her breasts larger by pushing your liquid form into them. You begin to feel horny, and you begin to have Jill's body masturbate. You can feel the orgasms, even while your main part is your own body, due to you having the bodies still connected. You have been a virgin for 16 years, and have always wondered what sex is like. You decide that now's your chance. You look around her room and find a condom, and are about to insert it into her, before learning that your abilities can prevent her from getting pregnant.
You quickly and forcefully shove your penis into Jill's vagina, wincing as you feel a pain in her vagina as you take her virginity. Once her body's pain has subsided, and her vagina is used to the feeling of your penis in her, you begin thrusting in and out of her. You realize you're feeling double the pleasure, and have fun with this. Your sexual tension lasts 4 hours without interruption, ending with you making Jill's breasts' nipples pop out of her shirt, and with your body sucking on one, while you have her body doing the same to the other.
What next?
