This was a custom video. Description: You make your sister a special beverage with a fart inducing serum when she takes a rest, you sneak into her room to listen to her farts. She can't stop and it's making you so hard so you stand over her and jack off. She wakes up confused and mad. Several months later, you try it again. You bring your sister a shake with the same serum. She wants to talk to you about when she caught you standing over her with your dick out. Right in the middle of the conversation she grabs her stomach and tells you to get out. You spy on her through the door crack and hear that the fart serum is working. She catches you spying and you admit to giving her the fart/gas serum. She gets mad and then feels bad for you. She lets you jack off while she continues to fart in your face until you cum on her ass.
