Luke awoke later upon hearing a strangely familiar voice, his eyes fluttering open to meet his male face staring back at him. He briefly considered that the events of the last hour had been some sort of fucked-up wet dream, but looking down he could still see his sister’s breasts and blonde hair. The face smiled, indicating that not only was it him, but somebody was inside of his old body. “Mind if I join the fun?” They said, reaching up a hand and grabbing a handful of Luke's left boob. They brushed the hair from Luke’s face and gave him a gentle kiss before he could protest.

“What are you- unfh!” Luke shuddered as the stranger in his old body rapidly pulled out the dildos and tossed them across the room, lifting his small dainty body before inserting his hot dick. Luke knew his member was on the larger side, but it was different feeling it inside of him, hot and warm and instinctively satisfying like nothing he had ever felt before. He could see the two of them reflected in the mirror across the room, acting as an extra dose of embarassment as Luke watched his new body get fucked from behind. “S-stop! What are you d-doinggg?” he cried, trying to protest against this degenerate act, but the fire in his chest from earlier was back and even more intoxicating. How is this happening to me? Why does it feel so good even though it's so gross! I’m not a girl! And this is incest! He thought to himself before the pleasures of being taken like a real woman overtook his mind and everything but fucking became a distant memory. The two spent hours fucking like horny rabbits on every surface and in every position, and it was the hottest, most incredible feeling Luke had ever experienced in his life.

As the two finally ran out of energy from countless orgasms, they collapsed on the bed panting as Luke finally had a chance sober up to what his original goal was and, more importantly, question was going on with his old body. Rolling over to his partner, he mustered the courage to ask. "W-who are you?"

His old body grinned like a madman. “You tried the Body Possession spell, right? Big mistake. You left your old body wide open for a wandering spirit like me to take it over, and now it’s mine until I’m done with it.”

“Seriously?” Luke complained, suddenly hyper-aware of his own feminine body. “You can’t trap me in here like this! Please give my body back!”

“Sure...” said the stranger, “I can give you your body... if you keep having sex with me for... I don’t know, a whole year?”

Luke’s jaw dropped. “You can’t be serious. I can’t be a woman for a whole year! I can’t have tits and a pussy and a fat ass!” He leaned into his old body, pressing his tits into his arm and trying to look seductive hoping that it would convince him to give in. “Besides, this is my sister! This whole thing is incest! You wouldn't want that, right?”

“She’s your sister?” the stranger laughed. “You are such a perv, but I guess that’s even better. Means we have more time for sex plus it’s extra hot knowing that it’s taboo. It must be weird being inside of your own sibling, huh? I’m sure you don’t mind since you picked it out after all, and besides, with the way you were letting the whole house hear your desperate moaning before, you didn’t seem to mind if people could overhear us. I hope for your sake your parents haven’t been home all this time!” He grabbed a handful of ass and began rubbing his hardening cock. “But enough talk. Ready to keep going, sis?”

Luke wanted to try and negotiate new terms. He wasn’t ready to be stuck inside his sister! And yet, as he felt the cock enter him again, those worries began to fade away. This body needed dick badly and was willing to do anything to get it. I guess I can deal with a year of this if the sex feels this good... He thought to himself as his mind drifted away, giving into his carnal desires for the second time of many to come.
