"....I want to show you something, can you hand me that carving knife?"
Jon did as he was told. Using the knife, she cut herself in half without so much as a flinch. Her disembodied legs then sat up and hopped of the bed, leaving Zoe to stand on her flat torso. Seeing her lower body walk on its own again weirded Jon, but to Zoe it was perfectly natural. Then suddenly, her ass turned to face him
Jon was puzzled "Zoe, what are you doing?"
"Fuck it!"
"What?"
Zoe's face was full of lust "Fuck it! I wanna watch you fuck my ass! And don't just fuck me, I wanna see your dick sticking out of me ."
"I'm not sure about this.."
"C'mon, it can't hurt me" Zoe gave him a playful gaze "And I see that look on your face, I know you wanna pleasure your sister."
Jon conceded "Alright, lets do this" He got up from the bed, grabbed her ass cheeks and pulled them to the side
"That's it!"
He shoved his penis into her. He heard Zoe start to moan, causing his erection to grow. He started to pump her as she groaned again
"YES... harder, harder"
He kept going at it, her insides stretching to accommodate him.
"SHOVE IT THROUGH ME!!!"
He thrusted as hard he could, his cock visibly sticking out out her like a skewer. Her putty vagina was completely wrecked.
"Uh Sis, I think I broke your vagina"
"Good! now turn me around!"
He did as she told, turning around facing her. In a move that shocked him again, Zoe tore off her own head, placing it on his boner as she started sucking him. Her disembodied torso started fondling her breasts, kneading and pulling on it. Her legs wrapped around Jon, hugging him passionately. The sight of all of this was too much for him and he finally unloaded into her, blasting her head off his dick, and on the floor with a splat. He sat back down panting, looking at the mess Zoe had become. A mouth formed on Zoe's neck.
"Wow, that felt amazing..."
"Yeah" Jon replied "But what do we do now?"
