A hairy, muscular man, alone in his den, decides to give his arm a unique workout. He lubes up his fist, curling his fingers invitingly. He leans back, legs wide, and pushes his fist into his hairy ass, groaning at the intense stretch. Slowly, he begins to fuck himself, his arm flexing as he sinks in and out, knuckles disappearing into his hungry hole. His cock leaks, slapping against his abs, as he picks up speed, his arm a blur, his ass greedily swallowing his fist.
