I was getting into a good jerk off session when my stepsister walks in and catches me…embarrassing! She was kinda cool about it though and strangely asked me to take sexy pictures of her. This was all overwhelming, but she is really hot, so I go along with it. It goes from snapping photos, to touching and the next I know she slurping on my cock & balls! She rides my big dick, her pussy gets super creamy. In the middle of pounding her from behind, we hear our stepmom hollering from the room. Ruined my orgasm!
