In the dimly lit lab, a hunky twink student awaits his professor's arrival, already naked and hard. The professor, a silver fox with a raging libido, enters, locking the door behind him. He drops his pants, revealing a throbbing cock that the twink eagerly sucks, swirling his tongue around the head and taking it deep into his throat. The professor then bends the twink over a lab table, spitting on his hole and pushing his thick cock inside, fucking him hard and deep, making the twink moan loudly. They switch positions, the twink riding the professor's cock, his ass bouncing up and down, before they both cum hard, their bodies slick with sweat.
