All of this slave's pain and suffering has finally paid off, he's finally earned the honor of taking Cybill Troy's strap-on cock up his eager ass. The rubber mistress selects a cock bigger than he's ever taken, telling him its this or nothing.
She fucks his ass, as always, without mercy, turning even his reward into an agonizing test as she fills his holes with all 12" of her thick cock, fucking him harder and deeper until he's good and stretched out for her.
Once she's satisfied, she him to lick all 12 inches clean.
