Fart punishment for shrunken step-son

Description: He has been misbehaving , excessively. at my wits end, i shrink him down, tie his and hands and feet and turn him into a human thong of sorts hehe. first he goes on over my shorts , with his face directly in front of my ass i fart. he still isnt apologizing or anything close to it so i sit down firmly on the chair, smashing his tiny body against my ass over and over. i fart some more and trap him under my ass with the gas around him. its some pretty stinky stuff. his attitude remains the same so i take it a step further and remove my shorts. now with his face directly in front of my asshole i fart and smash him with my ass some more. he finally says sorry and i take him off of my body. i tell him to take a nap and he'll be back to normal size afterwards.
