You have a fart session with me. I wear a diaper and I am super gassy. I give you instructions to jerk off and sniff my stinky nasty farts. At some point I feel I need to go to the bathroom and ask for your permission to go. You refuse to let me go untill you cum. I worn you that I will have an accident if I keep trying to fart. After I have the accident I make you smell my stinky diaper till you cum hard.
