My bro walked in on me while I was masturbating and didn’t say anything until I opened my eyes and realized he was there! I threatened to tell mom on him but suggested he help me out instead. It takes a bit of convincing but, after reminding him of what he’s missing, he agrees to a little competition. He wants to see who can make the other cum first by watching each other and mutually masturbating. It’s easy for me to cum, so it takes a lot for me to hold off, but I’m up for the challenge. I play with my Tits, ride my vibrator, talk dirty, shake my ass, and even show him my pussy and asshole while I masturbate. I end up making myself cum first, so I let him cum on me when he’s ready.
