He changes...

Shin flips you over as if you where nothing but a child. The old man stands behind you, pushing your legs wide apart as you sprawl on the medical table. His giant, dark and large cock presses against your backside.

Even as its clear he's going to fuck your ass it becomes clear that he's changing. Shady vines, whips of darkness, burst from his transforming body and slap down against your naked form.

His cock presses against your backside - and in the sex induced haze; whatever Shin is doing to you makes you want to fuck, fuck and fuck; even as you long for him to enter your schoolgirl form - tendrils of shadow curl around your neck and throat.

Shin slides his cock into your backside. You can't see him anymore. You can't turn your head. Tentacles of shadow have you pinned down on the medical table.

His cock slams into your backside. A tendril of dark flesh forces its way into your mouth and you gobble it down hungrily, sucking on it as if it was a cock.

He pounds his body against you again, fucking you from behind, making you cum again. Another tendril slips between your legs and slides into your cunt.

His cock and the tendrils twitch as one. You're fucked deeply in all your holes. More tendrils circle around your flesh.

"Accept!" roars the figure that was once Shin, a figure behind you, a figure fucking your ass, "Accept!"
