In an Argentine threesome, redhead Barbie Rivas and her stepbrother pass a joint, eyes locked, anticipation building. As they toke up, she fingers herself, moaning quietly, her brother watching hungrily. He smokes, his cock hardening, eager to join. They pass the blunt back and forth, their bodies pressing closer. She straddles him, grinding her wet pussy on his cock, her red hair cascading down. He grabs her hips, pulling her down as he thrusts up, filling her tight cunt. A friend joins, and they switch, Barbie taking both cocks, one in each hole, moaning and smoking, lost in pleasure.
