You and Jason made your way back to the bedroom. You grabbed his crotch through his girly yoga pants, excited to finally fuck again. Rubbing him up and down, you watch as he gets an erection immediately. It seems slightly smaller than before, but you don't care. Even though it had only been a few hours, it felt like it had been years since you last orgasmed. You pushed him on the bed and started pulling his pants off. He said nothing as you did this, discovering the panties he was wearing. You pulled these off his erection and used your giant breasts to give him a tit job. You hear his moans but they sound lighter this time, a little bit girlier. You found yourself mounting him and taking control, the complete opposite of your first fuck. "Yes! Mount me!" he says, in an even higher voice. You don't even notice his shortened stature (from 6'0 to 5'8) or his longer hair as you climb on top.
You start riding up and down his cock, taking pleasure in the fact that you were dominating him. Although you hadn't noticed yet, your mind was changing to become a more dominant bimbo while Jason's was turning into a more submissive woman. He was getting more feminine by the second; his 9 inch cock that you'd fucked earlier in the day had shrunk to a 6 inch one. Finally, you both orgasm.
Jason falls asleep immediately after, and you notice just how feminine he's body. He looks downright tiny compared to earlier, and his hair was down to his shoulders. "It looks like it is contagious. I wonder if I can turn back into a total bimbo?" You think, wishing to be the dumb horny slut you were. You knew Jason would be like that soon, which is your final thought before you fall asleep next to Jason.
