Horny hunk, dripping in sweat, takes his young trainee for a raw, bareback cardio session. The stud bends the eager teen over, spitting on his tight, virgin hole before plunging his thick cock deep inside. The trainee moans and gasps, his body trembling as he's pounded from behind, his own rock-hard dick dripping pre-cum. The room fills with the sounds of flesh slapping flesh, grunts, and the wet, sloppy sounds of their bodies joining. The stud's massive cock stretches the teen's ass, filling him completely as he slams in and out, fucking him harder and harder. The trainee's ass clenches around the stud's cock, milking him as he grunts and fills the boy's hole with hot, creamy cum.
