We just lay down after dinner and I just started to complain about my belly, what I ate for dinner made me so gassy... I suddenly fart and cover you with the sheets to make you smell it! I realize you have a boner from my farts so I tell you that I want you to keep smelling my farts and Jerk off! I see that you enjoy them, that you have a fart fetish so you have to jerk off the way I tell you to do! I am so gassy that is the perfect night for some jerk off instructions. I turn to different positions tell you to put your face directly on my ass to smell my farts, to breathe them while you're jerking off. I tease you even more showing my asshole for you to put your face! I eventually take my panties out and fart on them. I put them on a seal bag and tell you that every time you'll wake up during the night you will have to smell them... You will have to take them to your job so you don't ever forget about your wife. I keep giving you instructions to jerk off, farting even more while you have your face on my ass, and I will start a countdown for you to cum... making you cum to my farts at the same time.
