You start undressing him as you see his small nipple protruding from a small 32 A cup. You massage his breasts, and Marty feels aroused. "Fuck me, honey. My ass is ready," he said. You look at his rear. He has a nice round butt. Although, his butt is nowhere as big when he was a girl. Wait, is that weird thought coming again. He never was a girl.
Without wasting more time, you start thrusting your penis to your boyfriend rear. His flacid penis begins to harden. When you both reach climax, you ejaculate at the same time.
You both feel exhausted and just lay on the bed, cuddling. He feels it was his best sex even compared to when he was a girl. Suddenly, his previous memories as a girl return. He was in vacation with his boyfriend. They made a reservation for TF room from the TF resort. He got changed into a cute femboy since his boyfriend fantasized about it. However, the room helps his mental transition and almost erases his previous memory.
"Wait a second, I'm not Marty," your boyfriend suddenly said. "What do you mean? Do you want to do some roleplay, honey?"
"No, I'm not a boy. I'm changed into a boy because you used this room to change me. Now, change me back into your girlfriend."
"Wait, hold on. I don't understand, babe. You're always a boy. You're just a boy who likes to crossdress as a girl." Your boyfriend tried so hard to change back to his previous body. But, it doesn't work. The change should be initiated by you when you changed him.
"Look, just try to concentrate with your mind and change me back into your regular girlfriend."
"What girlfriend? I don't know what you're talking about." You are really confused now. Your boyfriend suddenly confessed that he was a girl for the whole time. On the other hand, you feel excited if what he said is true. You can change him into whoever you want.
"I was your girlfriend in a few minutes ago. I was a blonde girl with big boobs and big butt, also had a pussy. Not this male body. Please, for the love of God, hun! CHANGE ME BACK," he starts to scream as he loses his patience. He doesn't want to get stuck in that body forever. He is not a boy.
Your heart is racing. You start having an idea of what you will change him into.
"Okay, okay. Alright,... hold on, let me I concentrate..." You start to focus.
