My friend's boyfriend, a tall, muscular black man with a monster cock, catches me staring. I've always had a thing for black dick, and his is huge. He smirks, knowing I want it. We head to his car, parked in a secluded spot. He pushes me onto the backseat, tearing off my clothes. His big, black cock springs out, already hard. He spreads my legs, pushing his thick head against my asshole. I moan as he enters me, his cock stretching my hole. He fucks me hard, his big dick hitting my prostate with each thrust. I stroke my own cock, matching his rhythm, until we both come undone. He pulls out, his cock glistening with our mixed juices, and I lick it clean, savoring the taste of our taboo encounter.
