Yes

Isaac, your so called best friend, finally pulled his dick from your pussy, leaving behind both a warmth and an emptiness inside you. He then took your hand and guided you to his room. There he sat on the bed and told you to suck his dick.
Your males self was still around, still conscious, distraught that Isaac’s sperm might have already fertilized your egg.
Your female self knelt between Isaac’s legs and started sucking his dick, quickly getting him back to full erection. She moaned and slurped and looked into his eyes while pressing her breasts together. Before you know it, Isaac was already claiming he was about to cum again.
Doe released his dick and threw herself onto Isaac’s bed. She spread her legs wide and said, “Do it inside me, Isey.”
Isaac didn’t waste time accepting her offer. He pushed inside your pussy and immediately flooded it with another batch of baby batter.
“Bastard.” Your male self groans inside your head. “You really want me to stay a girl? You’re not a friend, you’re a traitor.”

When he finished orgasming, Isaac starts fucking you. He thrusts inside your sperm filled pussy, gropes your breasts, licks your nipples. Your female self even locks her legs around his waist and pulls him further inside. You feel a second orgasm rise and soon she cums all over Isaac’s treasonous dick.

When she orgasms, you suddenly feel a wave of energy leaving you. It is similar as when you usually transform back into a man, only in reverse. Could it be your fate has been sealed?

When Doe finished orgasming she pushes Isaac on the bed and mounts him. She then rides him like a cowgirl, pressing her breasts together with her upper arms while her hands caress his chest.
“Yeah, baby. This’ll be us for now. Fucking merrily without any lame friends interrupting us.” Isaac says.
When you hear him speak those words your resistance falters and say, “Please, don’t let me become a total slut.”

Isaac slams his dick inside your pussy, ready to cum again. Doe grinds her pussy on his rod, close to orgasm herself. When Isaac cums for his third time he puts so much sperm inside you, it starts to spill from your cunt and drips along his shaft, covering his balls.
Feeling Isaac’s dick throb inside you makes you orgasm again. Once more you feel yourself weaken. A darkness starts to surround you and your curse is fulfilled, you remain.

Your lay down on top of Isaac, pressing your breasts into his chest. Isaac wraps his arms around you and says, “I love you, Doe. Ever since the first time I saw you transform. Will you stay with me?”
“Hmmm.” Doe moans. “That last orgasm was supposed to transform me back. Instead I’ve stopped hearing John in my head. I guess I’m here to stay now.”
“Perfect.” Isaac says, and gives Doe a french kiss.
