You've been caught red-handed this time! You snuck into your little sister's closet to watch her undress... like a true pervert! This isn't the first time and your sister knows that! She busts you then busts WITH you! She wants you to get closer and then encourages you to stroke with her. Her huge futa cock puts you in a trance, an animalistic state and you just can't resist! She lets you touch it and then cums all over your cock, which you then use as lube to cum.
