face sitting & fart trapping mask

Description: This slave has his wrists and ankles tied, with a leather mask over his head, its zip and his air under my control. he will have no choice but to endure my face sitting and farting. to maximise his suffering i am going to fart while the mask is zipped down, then immediately close it, trapping in my stinky fart in his air pocket, then sit back on his face. no air, unable to move, trapped under my ass. hahahaha. some ballbusting and cock slapping to top it all off.
