In this raunchy, instructional twist, Selena Vega, the busty Venezuelan wife, teaches her husband, Thethelemitevegas, how to solve a Rubik's cube while she gets fucked in front of him. As he concentrates on the puzzle, she starts by sucking his cock, then rides him in cowgirl, her huge tits bouncing enticingly. She takes it doggystyle next, her massive boobs swaying with each thrust. The husband, oblivious to her cheating, finally solves the cube, but not before his voyeuristic wife cums hard on his cock.
