Chapter Text
Bruce pulled the lacy strip of fabric to the side, slicking up the tight ring before pressing the considerably thick capsule in. His finger followed, guiding it deeper inside up to the knuckle. Peter let out a soft whine at the intrusion but he didn't try to squirm away, clenching reflexively around the thick calloused finger.
"Good boy." he hummed, slipping out of the tight heat with a wet pop to grab the steel beaded plug that lay glinting ominously on the bathroom counter Peter was bent over, freshly bathed and half dressed in nothing but a pair of cheeky lace panties and a matching black leather garter. Peter whimpered at the reflection in the clearing mirror, watching the man lube up the frankly intimidating toy.
While the beads were significantly smaller than the cock he had sucked off earlier in Tony's office, they weren't exactly 'small'. Especially the one at the base of the stack with the pulling ring dangling from it.
"You'll need to be properly stretched if we're going to have a lot of fun this weekend." The tone was light but the touch of the smallest steel bead at his rim had Peter's heart kicking up a notch. He felt the first bead pop through with minimal resistance. And then another and another before the real stretching began.
But oddly enough, the man didn't push as he had at the beginning, opting for shallow thrusts in and out with just the three. He could feel his rim grab at each bead that slowly pushed in and out.
It took about ten minutes before Peter could feel himself growing hot and sensitive at the same shallow strokes, slowly losing the ability to keep his mouth shut. Had he had the state of mind to look up at the mirror, he could have caught the wolfish smile grow on Bruce's face and noticed the man's eyes growing darker with lust aware of what was happening and what was to come.
It was then a new bead was pressed in, pulling a moan that echoed around the room.
"Feels good, doesn't it?" Bruce murmurred, trailing a hand up Peter's thigh, skimming his hips to cup the lace covered bulge. The heat and pressure alone had Peter's cock pulsing, straining against the growing tightness.
"Oh god." Peter whimpered rutting against the man's palm, trapped between two overwhelming sources of stimulation. "Relax, baby." he cooed, pulling the fourth bead back out to wiggle it back in all the while slipping his hand past the waistband to get inside skin to skin. That was when Peter came with a choked grunt, painting the man's hand and part of the fabric with his milky release.
"So sensitive." Bruce teased getting straight to work with his come coated palm wrapping his rough hand around the flaccid cock, using Peter's own come as lube to pump the cock back to straining before starting on the fifth and final bead.
Peter jerked in Bruce's hands, cries growing louder along side the sensitivty. In and out, stretching his rim while pumping him slow was punishing. But he craved more. He needed more to chase the mind numbing white hot pleasure. The stretch of the final bead required more than a little work, but Bruce was a patient man. One that leaned close to precision in all aspects. Be a tough dom as he may, real avoidable injury wasn't something he wanted.
So he stood rooted by Peter's ass, stroking his cock slow and steady while pulling and pushing the final bead in past Peter's rim little by little until the entirety popped in, locked in place by a smaller bead that stoppered his rim from the outside connected to a flared end.
Peter came for the second time shortly after, smallest bead just barely skimming across his prostate in addition to the quickening speed of the hand stroking his cock with a tightened grip.
Bruce wiped himself off on the inside of Peter's panty this time, letting the newly flaccid cock sit in the tight dampness. Peter mewled in protest at the wet slick. But the discomfort was all but forgotten at the feeling of the back of his panty getting moved back as it had been, covering the toy and its base.
And without warning, Bruce took the fabric of space between the cheeks in his fist and pulled up, forcing the lacy fabric into the crevice of Peter's crack.
"Ahh!" Peter yelped, hands scrambling atop the granite countertop for some level of support as his body was pitched further forward onto his tiptoes. But the pulling grew stronger and further up until he felt his toes leave the ground. He wailed, cock straining hard while the pressure of the pull into his crack pushed the stopper bead in deep enough that the first two pressed directly onto his prostate.
"There we go. That should keep them in place until Tony gets here.." Bruce placaded, letting Peter slowly back down to his feet , straightening out the rumpled lace from his crack.
