Donovin, the straight-laced stepson, finds himself in a compromising position with his stepdad, Muscled Madison. Cornered and vulnerable, Donovin is forced to service Madison's enormous cock, taking it deep into his throat until he gags. Madison then bends Donovin over, spreading his ass cheeks to reveal his tight, untouched hole. With no lubricant but spit, Madison roughly pushes his way in, making Donovin wince. He fucks Donovin hard, using him as his personal fuck toy, before pulling out and coating Donovin's back with his thick, ropes of cum.
