My sister's boyfriend allows me to pleasure him following school at her residence

After school, I visited my sister's place and her boyfriend allowed me to pleasure him. I gave him a blowjob and then rode his cock in cowgirl position, making me feel like a cheating girlfriend.

I'm hanging out at my sister's house, waiting for her to get home from school. Her boyfriend comes over, and it turns out he's down for some action. I'm all for it, and we start getting frisky. He's got a rock-solid body and a throbbing cock that's just begging for attention. I'm a total hottie, and I know it. I've got the body and the moves to match. We get down to business, me giving him a mind-blowing blowjob before we move on to some intense riding. He's got a tight ass that's just as amazing as his sister's, and I can't resist the urge to take a bite. It's clear that he's into me, and I'm into him. We keep going, our bodies entwined in a dance of pleasure. The sight of his big cock disappearing into my tiny pussy is one I won't forget. We finish strong, both of us completely satisfied. It's a wild ride, but who says cheating is wrong when it looks this good?.
