ガールフレンドはあなたがけいれんしているのを捕まえて、あなたにあなたの精液を食べさせました

Your girlfriend catches you touching yourself while she's turned around. You know the rules, any time she catches you, you have to finish the job. You have to jerk off and eat your cum while she watches. This time, she makes you cum into her hand, and then suck your cum off her fingers.
