At BreederFuckers, Joseph’s body is like hot hard steel bursting with strength and he jerks away and struggles against his binds. That big monster cock of his can barely be contained in his tight white pants, which they ruin so he’s totally exposed. He grunts in humiliation because of the feelings of pleasure and pain coursing through his body as his cock is manipulated and stroked and he can’t stop it from becoming achingly engorged. When his foreskin is peeled back, his glans throbs bright and pink against his dark skin.
Derek slides a vibrator up his arse, screwing the fucker deep. They don’t want the tender head of his cock shrinking away, so his bell end is strung up. His big full nuts are tied up. The incredibly sensitive head of his dick is teased with a vibrator till he feels the pleasure shooting through his body no matter how he grits his teeth against it. He’s drained of his semen. This big studly man’s genitals are his pride and joy, but now they are owned fully.

At BreederFuckers, big arrogant straight studs like Kevin like to live the high life. Fancy suits and fast cars bought on credit. He has no way to pay for this flash lifestyle when his debts are due. The doctors are in to make this masculine fucker pay by performing a very unusual procedure on his body. Kevin is bound in the operating chair and disrobed from his suit. All that’s left are his skimpy white designer pants. Dampen them slightly, and it’s like looking through a window at his tight hetero anus. His pants are torn away, revealing his arse fully.
The doctors fill his anal cavity with water, and to prevent any of it coming out they stuff a butt plug up his rectum. Now his insides are under such pressure Kevin can barely stand it. Dave skillfully manipulates his cock until he grows a big throbbing erection. Noticing what a big opening his pisshole makes, they amp up the punishment by sliding a rod down his urethra. Kevin is totally overwhelmed with the pressure building in his anus and his cock being fucked. This is when his dick is seized and pumped insistently till Kevin releases a load of fresh semen all over his stomach and chest. At the same time the butt plug is yanked out released all that built up water pressure. Kevin is left dizzy from the overwhelming sensations inflicted upon his body.

I am not sure what is going on here, but it sure looks interesting!

The above pictures are from Master Mike and one of his prisoners. No word on whether the guy ever escaped from the quadruple cuffs welded together.
At Dream Boy Bondage, supreme sadist Jared continues to burn Doug
Supreme sadist Jared continues to burn Doug, lobbing streams of searing hot wax on his torso and legs, then his cock and balls. Doug buckles and screams as his skin burns, every muscle in his young body flexing, his back arching, his cock flopping around. The wax hardens on his skin, clinging to every little hair. Jared decides the best way to remove the wax is with the flogger. He beats Doug mercilessly, then flips him over onto his stomach. “We’re not done yet,” Jared announces. You guessed it: The whole process is repeated on Doug’s beautiful back and ass.

At Dream Boy Bondage, Riley moans in agony, stretched taut on the rack, completely naked and vulnerable, cum drying on his abs from being jerked off, when Jared re-enters the torture chamber.
“Please, just let me go,” Riley says. “You look great stretched out like that,” Jared replies, caressing his captive’s quivering body, then turning the crank on the rack several more turns, taking Riley’s agony to the next level. “Agggggg,” the prisoner screams; the pain is unbelievable. Jared just walks away, snickering, letting his captive moan. He returns an hour later and unchains Riley’s legs, raising them up high and spreading them wide, stretching his captive’s ass. You guessed it: Riley is brutally fucked with a huge, tapered dildo.
