I walked into the apartment already hard, the plastic crinkle of my diaper loud under my jeans. Mark was waiting on the couch in nothing but a tight black tank and his own thick diaper, the front sagging a little from the load he’d already let go. He looked up with that slow, dirty grin and patted his thigh.
“Come here, boy. Show me how full you are.”
I stripped down to just the diaper and crawled onto his lap. The moment my padded crotch pressed against his, heat flooded through me.
Mark’s hand slid straight down the back of my diaper, fingers pushing into the mess I’d been holding since lunch. He groaned low in his throat.
“Fuck, you’re soaked. Been leaking for hours, haven’t you?”
“Yeah,” I breathed, rocking my hips so the wet bulk rubbed against his hardening cock through his own diaper. “Didn’t want to change without you.”
He didn’t answer with words. He just shoved two fingers deeper, spreading the mess around my hole while his other hand pressed the front of my diaper, grinding the soggy padding against my cock. The smell of piss and powder filled the room. I moaned and pushed back onto his fingers, the diaper squelching obscenely.
Mark ripped the tapes open on my diaper, letting the heavy, warm front flop down. My cock sprang out, shiny with piss. He wrapped his fist around it and stroked once, slow and filthy, then brought his hand to my mouth.
“Taste what you did.”
I licked his fingers clean while he watched, eyes dark. Then he flipped me onto my back on the changing mat he’d already spread out. He wiped me roughly, not gentle, the cold wipes making me gasp, then powdered me thick and heavy before taping a fresh diaper on so tight the plastic stretched over my balls.
“On your knees,” he ordered.
I got up, the new diaper already starting to feel warm and tight. Mark pulled his own diaper down just enough to free his thick cock, already leaking. He pushed me forward so my face was in the couch cushions and the back of my diaper was yanked open again. This time his cock slid straight into the mess, using my own filth as lube while he fucked the open back of the diaper.
Every thrust made the front of my diaper rub my cock. The wet squelch, the smell, the way he grunted “good boy, take it” right in my ear—it all pushed me right to the edge. I came hard inside the fresh diaper, pulsing thick ropes against the padding while Mark kept pounding the back, using the mess like it was made for him.
When he finally pulled out he taped the diaper shut again, trapping everything inside. Then he sat me on his lap, my loaded, cum-filled diaper squishing under me, and fed me a bottle of warm milk while he stroked the front until I was hard again.
“Round two,” he whispered, already reaching for the wipes. “This time you’re going to piss while I’m inside you.”
I nodded, already leaking into the diaper again, already lost in it.
