Farting Jerk off Instructions

You've just arrived home and your girlfriend is laying around in bed. She tells you she's been out for Mexican food and you already start to get excited about the farts you know that will produce. She says that she is going to fart alot, and she is going to let you watch. But she wants to see how much her farts turn you on so she's going to encourage and instruct you to jerk off while she farts. (Custom video so the name "alan" is used frequently in the clip)
