I caught my step-brother in the middle of the living room jacking his cock in front of the full body mirror! I was shocked but then was rushing to move his hands away from his cock so I could take a look. After some persuasion, (and a little strip tease) he moved his hands away and started masturbating in front of me. I told him how I wanted him to stroke it and where I wanted him to cum on me. I made him edge before counting down from 10, making him blow all over my big tits.
