MCU prompt please, where Tony introduces Steve to all the new M/M sex toys if that’s ok with you? Maybe Steve has to be in bondage since his reactions keep knocking Tony off the bed otherwise? LOL – @chrisatplay
“You’re a modern man now, Cap. Time to indulge in the modern man’s sexual proclivities.” Tony holds the door open for Steve and ushers him inside with a grandiose gesture.
Steve gives him a derisive look. “I seriously doubt sex has changed that much since–”
He stops short when he walks inside and spots the–well, he’s not really sure exactly what he’s looking at. That over there is definitely a wall of plastic penises. There are…contraptions hanging from the ceiling. Whips. Chains. Aisles upon aisles of DVDs.
Tony walks past him with a smug smirk on his stupid face. He picks up a forearm-sized black phallus with a suction cup on the end, wiggles it toward Steve while he talks. “Silicone. Best thing science has given us since…well, you.”
Steve hisses inward through his teeth, bites back the moan at the back of his throat. “C’mon, you can do better than that.” His voice is muffled against the wooden plank he’s tied to, hot against the side of his face.
Steve’s ass is raw from the flogger. And the flail before that. And his wrists and ankles are burning from where he keeps writhing in his restraints. His whole naked body is on fire, muscles tensed every time the paddle cracks across his bare ass.
“One more word and I’m shoving a ball gag in your pretty albeit filthy mouth,” Tony replies. Crack.
Steve winces. The plug in his ass keeps grinding against his prostate. He keeps fucking onto the plank. It’s uncomfortable and it hurts but it’s friction. He’s been on the edge for what feels like forever, keeping himself from coming by sheer force of stubborn will.
Tony steps away. Steve can hear him toss the flogger on a steel table covered in sex toys and broken electronic parts, because only Tony Stark would have a lab that doubles as a sex dungeon.
Steve isn’t impressed. The thought prompts him while he’s waiting. “May not have had as many fancy toys back in the day, but you could still make sex hurt with nothing but your hands. No cuffs, but we had rope, neckties. Flogger’s alright. Still, nothing beats a good leather belt.”
“Got any old timey comparisons for this?”
Steve hears a soft click, and the plug in him starts to vibrate. He can’t hold it back; he lets out a shocked groan, fucks into the plank. All the breath is taken out of his lungs. If he’d had this before the serum, he would have gone into cardiac arrest. “Fuck.”
“Quarter in the swear jar,” Tony says. The distinct, ominous snap of Tony slipping his belt out of its loops echoes in the room.
Steve doesn’t have time to prepare himself, can barely get in another breath before Tony cracks the belt against his already welted ass. Steve cries out.
He composes himself enough to bite out, “I’m–I’m gonna…”
“You can hold out, Cap. Three more,” Tony replies. “Count.”
Steve stills his hips but it takes every ounce of his willpower and focus. Tony hits him again, this time lower, on the backs of his thighs where the pain is less. The newness is sharp and the wake of it throbs through his body, intensifying the vibration. He can feel it all the way in his teeth.
“One,” Steve says, voice wavering.
Crack. Steve gasps. Pressure builds at the base of his gut, forcing his breath to come out in shallow bursts to keep from coming. “Two.”
“One more. You can do it.” Tony slams the belt against Steve’s ass one more time.
Steve’s body is strung tight like a bow. He lets out a small, broken half-sob. Every dry retort he could make falls dead on his lips, replaced by, “Please, Tony–”
The belt clatters to the ground. Steve can feel Tony slot himself behind him. Fully clothed. Hands massaging the welts of Steve’s ass. Breath hot on the back of his neck. Grinding against him, pushing the plug further inside.
“Go ahead,” Tony whispers.
Steve fucks himself against the plank two more times and comes hard, hot all over his abdomen and the plank, pulling at the restraints until the wood begins to splinter. Tony grips his hips, bites his shoulder, digs his nails in. Steve sees stars behind his eyes and nearly blacks out.
Everything is a blur as Tony leaves for a minute, returns and unlatches the cuffs. Steve falls back, but iron arms catch him.
As he guides Steve up to the bedroom, he says, “I may have underestimated the utility of leather belts.”
