Mark shoved the door shut behind him and shoved Jake face-first against the wall.

"Strip. Now." His voice was low and rough, no bullshit. Jake peeled off his shirt, kicked out of his jeans, and stood there naked, cock already half-hard from the order alone. Mark didn't waste time. He grabbed the heavy leather cuffs from the table and snapped them around Jake's wrists, yanking them behind his back and clipping them together. "On your knees."
Jake dropped. Mark looped thick rope around his chest, pulling it tight under his arms and across his pecs until the fibers dug in. Another length went around his thighs, forcing his legs apart. Mark worked fast, knotting everything so Jake couldn't move more than a few inches. When he was done, Jake's arms were pinned, his chest bound, his legs spread and useless. His cock stood straight up, leaking.
Mark grabbed a fistful of Jake's hair and pulled his head back. "Look at that fucking dick. Already dripping like a slut." He slapped the head of Jake's cock once, hard enough to sting. Jake grunted but stayed quiet. Mark unzipped and pulled out his own thick cock, slapping it across Jake's face. "Open."
Jake opened his mouth and Mark shoved in deep, no warm-up, just straight to the back of his throat. He fucked Jake's face in steady thrusts, holding his head in place with both hands. Spit ran down Jake's chin. Every few strokes Mark pulled out just long enough to let Jake gasp, then rammed back in. When Mark finally pulled free, strings of spit connected his cock to Jake's lips.
He hauled Jake to his feet and bent him over the padded bench in the middle of the room. More rope went around Jake's ankles, tying them to the bench legs so he was spread wide and helpless. Mark ran a hand over Jake's ass, then brought it down hard. The slap echoed. He spanked both cheeks until they glowed red, then reached between Jake's legs and grabbed his balls, squeezing just enough to make him squirm.
"Stay still or I add more rope," Mark said. He lubed two fingers and pushed them straight into Jake's hole, no teasing. He pumped them in and out, stretching him open, then added a third. Jake pushed back as much as the ropes allowed. Mark pulled his fingers out and lined up his cock. One hard thrust and he was buried balls-deep. He fucked Jake with short, brutal strokes, the bench creaking under them. Every time Jake tried to move, the ropes tightened and bit into his skin.
Mark reached around and wrapped a hand around Jake's cock, stroking it in time with his thrusts. "You gonna come with my dick in your ass?" he growled. Jake nodded, breathing hard. Mark kept pounding until Jake's cock jerked and shot across the bench. Mark didn't stop. He fucked him through it, then pulled out, untied one ankle, flipped Jake onto his back on the bench, and retied the leg. Now Jake was on his back, arms still pinned under him, legs spread and tied down.
Mark climbed on top, straddling Jake's chest. He jerked his own cock fast and shot thick ropes across Jake's face and open mouth. Some landed on his bound chest. Mark wiped his cock on Jake's lips, then reached down and rubbed the cum into his skin.
He left Jake tied there for a few minutes while he caught his breath, then started untying him slowly, rubbing the red marks the ropes left behind. When Jake was free, Mark pulled him up and kissed him hard, one hand still gripping the back of his neck. "Shower. Then we're doing it again with the spreader bar." Jake nodded, already hard again.
