Brendan Patrick wakes up chained to a wall in an unfamiliar place. He soon learns that he is the Ass Master’s newest experiment. The Ass Master hides and watches his new Irish Stud and tells him that if he wants to leave, he must first complete two challenges. Brendan finds a variety of butt plugs in the room. He stretches his hole open with the different butt plugs before facing the first challenge: The Sybian. Brendan ferociously rides the Sybian, while stroking his cock. He feels the need to cum from the powerful vibrations filling his ass, but he must hold off until he takes on the next challenge: the Shock Spot. Brendan is tied down to a mattress while the mighty fucking machine fills him up. The Shock Spot fuck-starts Brendan’s tight hole until an eruption of cum bursts forth and covers Brendan’s chest. Brendan is proud to have taken on the challenges of the ass master, and licks up his fresh cum before leaving.
