As the master's fingers delve deeper, steampowerBTTM's body convulses, his cock straining against its cage. His master, sensing the pup's impending orgasm, withdraws, leaving steampowerBTTM begging for more. The master smirks, uncuffing the pup's hands. "Use your fingers," he commands. SteampowerBTTM eagerly complies, fucking his own ass with three, then four fingers, his massive hole swallowing his fist whole. His master watches, stroking his cock, as steampowerBTTM brings himself to the brink of orgasm, his body shaking, his ass dripping with piss and lube. With a final, guttural moan, steampowerBTTM collapses, his ass still gaping, his body covered in sweat and spent fluids, his master's command echoing in his mind: "Clean up this mess, pup."
