Tied up and gassed with gas mask

Description: I was in exactly the right mood to destroy a fart bitches pathetic face, but my god i did not expect the smell that came out! the gas i've had over the last couple of days has been the worst i've ever delivered to a poor slave's face by far! and using a gas mask makes it 100x worse! 100% of the smell gets directly to his nostrils. gets trapped in there, pure desperation!  nose & mouth farts. of course.yum. #facesitting #lesdom #smothering #farting #savage #femdom #sweatyfarts #struggle #brutal #nomercy #nosefarts #mistress #mouthfarts #domme #grossdom #facefarts #stinkyseat
