He grabbed the thick diaper and shoved the front panel right up between my legs without any warning. The crinkle was loud in the quiet room, and the padding pressed hard against my cock, already half-hard from the way he'd stripped me down. "Stay still, baby," he growled, pulling the tapes tight on one side then the other, forcing the bulk to cup my balls and squash everything into place. The pressure made me leak a little right into the padding.
I moaned low and dirty, hips twitching. He shoved two fingers under the leg cuff to check the fit, dragging them along my taint and up to the base of my shaft. "Fuck, you're already soaking this thing," he said, voice rough. He pressed the heel of his hand down on the front, grinding the diaper against me in slow, heavy circles until my cock throbbed and I started to get fully stiff inside the soft, padded prison.
"Look at you," he muttered, pushing me back onto the bed so my legs spread wider. He shoved the diaper again, this time from underneath, lifting my ass and making sure the seat was snug and full against my hole. The sensation was intense, the thick material rubbing every time I moved. I could feel the wetness spreading where I'd already started to dribble pre-cum. He leaned in and spat on the front, then rubbed it in with his palm, turning the outside damp and slick.
I reached down to touch it, but he slapped my hand away. "No. You don't touch. I shoved the diaper on, so I control it." He climbed over me, straddling my thighs, and started rocking his own hard cock against the padded bulge between my legs. The friction was muffled but constant, each thrust making the tapes strain and the material bunch up tighter. My balls ached, trapped and squeezed, and every grind sent sparks up my spine.
He reached behind him, grabbed a bottle of lube, and poured it straight down the front of the diaper. The cold shock made me gasp, then the warmth of it mixing with my own mess took over. He shoved his hand inside the waistband, fingers wrapping around my cock through the now-slick padding, jerking me in short, rough strokes. "That's it, fill it up for me," he ordered. I bucked up into his fist, the diaper crinkling loud and wet with every movement.
When he pulled his hand out, it was coated. He smeared it across my mouth so I could taste the mix, then shoved two fingers between my lips. I sucked them clean while he kept grinding on the outside of the diaper, his cock leaving streaks on the plastic backing. My own orgasm built fast and dirty, the pressure inside the diaper turning unbearable. He knew exactly how to shove and press to push me over.
I came hard, pulsing thick ropes into the padding, the diaper swelling and growing even warmer and wetter around me. He didn't stop grinding, milking every twitch until I was shaking and oversensitive. Only then did he yank the tapes open, shove the front down, and stroke himself off onto the mess inside, adding his load to mine. The combined heat and slickness made the whole thing obscene and perfect.
He taped it back up tight, forcing all that filth to stay pressed against my skin. "Good boy," he said, giving the front one last firm shove. "Now you wear it until I decide it's time to change you." I lay there panting, the heavy, used diaper sagging between my thighs, already craving the next time he'd grab it and shove it into place all over again.
