Two grown brothers, both well over thirty, had kept their filthy secret for years. Jake and Ryan lived together in their late parents' old house, and every night after the lights went out they turned the master bedroom into their private playpen. No one else knew how deep their need ran.
Jake always started it. He would walk into the room wearing nothing but a thick white diaper already taped around his hips, the plastic crinkling loud with every step. "Get on the bed, little brother," he growled, voice low and rough. Ryan obeyed fast, stripping down and lying back with his legs spread. Jake grabbed the fresh diaper from the stack on the nightstand, powdered Ryan's cock and balls heavy, then pulled the diaper up tight and taped it snug. The front bulged obscenely once Ryan's dick started to stiffen.
They didn't waste time with talk once the diapers were on. Jake climbed over Ryan and ground their padded crotches together, the thick padding squishing and rubbing their hard cocks through the plastic. The sound was wet and filthy. "Fuck, your diaper feels so good against mine," Jake grunted, thrusting harder. Ryan moaned and grabbed Jake's ass, pulling him down tighter so the diapers mashed together.
Soon the tapes came loose. Jake ripped Ryan's diaper open, exposing his leaking cock. He wrapped his hand around it and stroked fast, thumb smearing the precum. "You gonna piss in this one for me first?" he asked, dirty and direct. Ryan nodded, face flushed, and let go. Hot piss flooded the open diaper, soaking Jake's fist and running down Ryan's balls. Jake kept stroking through the warm stream, then leaned down and sucked the head of Ryan's cock clean, tasting the mix of piss and precum.
They switched. Ryan tore Jake's diaper apart next, pushed him onto his back, and buried his face between Jake's legs. He licked and sucked Jake's balls while Jake pissed into his own ruined diaper, the liquid soaking the sheets beneath them. Ryan's tongue moved lower, rimming Jake's hole while the piss kept flowing. Jake groaned and pushed down on Ryan's face, grinding his wet diaper against his brother's chin.
When they were both soaked and hard again, Jake rolled Ryan onto his stomach, pulled the back of the fresh diaper down just enough, and pushed his cock straight into Ryan's ass. No lube beyond spit and piss. He fucked him deep and steady, the diaper crinkling with every thrust. Ryan pushed back, begging for it harder. "Breed your little brother's diaper hole," he panted. Jake slammed in faster, balls slapping the wet padding, until he unloaded with a long, rough groan, filling Ryan up.
They stayed locked together while Jake softened inside him. Then Ryan turned over, his own cock still trapped in the front of his diaper.
Jake sat on it, letting Ryan fuck up into the messy, piss-soaked padding until he came too, shooting thick ropes that mixed with everything else inside.
Afterward they taped fresh diapers on each other, slow and careful, kissing messy and deep. They lay side by side, arms around each other, the room smelling like sex and powder and piss. No shame, no hurry. Just two grown men who knew exactly what they needed and took it from each other every single night. The diapers stayed on until morning.
