Suddenly Jon was back in his bedroom Karyn was there too.
"C'mon Jon please... please please, let me, I've been a chick for over a month, I've had a period, I really want to be done with all this, boobs, bras, and definitely periods."
Jon was momentarily confused... but put the pieces together. Karyn had been a boy and must've been turned into a girl via a blowjob, and she wanted Jon to let her blow him to trade genders.
"I-I don't want to be a chick" he'd made the wish to see other people change and out of curiosity to who would change and how quickly back and forth.
"Niether do, but trust me, a blowjob feels, just ridiculously good." Karyn pleaded trying to undo Jon's pants.
Jon got curious, just what kind of feeling had he created with his wish... maybe it would be worth it... though he'd be stuck like a chick until he was desperate enough to do the deed.
