The dorm room was always too quiet at night, the kind of silence that pressed against Mark's chest and made every thought louder. At twenty-one, he was supposed to be focused on midterms, on the engineering projects that kept him up until dawn, on the casual hookups that never quite satisfied the deeper ache he refused to name. Instead, the package arrived on a Thursday, plain brown cardboard that he hid under his bed like contraband. Inside were the diapers—thick, crinkling, adult-sized but unmistakably meant for regression. He told himself it was just curiosity, a one-time experiment born from too many late-night searches.
The first night he tried one, his hands trembled as he unfolded the plastic. The material felt cool against his skin, the tapes securing snugly around his hips with a soft, final sound. Mark lay back on his narrow bed, staring at the ceiling, waiting for shame to flood in. It didn't. Instead, a slow warmth spread through his belly, not from the diaper yet but from the simple act of wearing it. He shifted, feeling the bulk between his thighs, and his cock stirred despite himself. He didn't touch it. That was the rule he'd set: no rushing. Just feel.
Days passed in a haze of classes and the constant awareness of the secret beneath his jeans. He bought more, ordering in bulk now, hiding the receipts. The regression crept in gradually. At first it was the way he caught himself sucking his thumb while studying, the taste of skin grounding him in a way textbooks never did.
Then came the bottles—sippy cups at first, filled with warm milk he drank alone in the dark. Each time he wet the diaper, it was an accident at first, a slow leak that made him freeze, heart pounding, before the heat spread and the plastic swelled. The sensation was intimate, almost loving, the way the material clung and warmed. He found himself rocking subtly, the friction against his hardening length sending sparks up his spine, but he always stopped short of coming. The denial made the next step more inevitable.
By mid-semester, the psychological shift had taken root. Mark started skipping parties, preferring the quiet ritual of his room. He'd strip down, powder himself carefully, the talc dusting his skin like a caress, and tape the diaper on with deliberate slowness. The crinkle was a lullaby now. He bought a pacifier online, the adult kind with a soft silicone nipple that fit perfectly between his lips. Sucking it while padded made his mind drift, thoughts simplifying to the feel of fullness, the faint scent of baby powder, the growing pressure in his bladder that he no longer fought. When he finally let go, the rush of warmth was erotic in its surrender—the diaper sagging heavily, the heat radiating against his balls and cock, turning every shift into a teasing stroke.
He met her in the library, a psychology grad student named Lena who noticed the way his eyes glazed during late-night study sessions. Their conversations started innocently enough, but she had an intuitive eye for hidden needs. One evening in his dorm, after too much wine and whispered confessions, she asked if he wanted to regress further. Mark's face burned, but the nod came easily. She became his caregiver in careful increments: changing him with clinical tenderness that quickly turned sensual. Her fingers lingered as she wiped him clean, her breath warm against his thigh. The first time she powdered him, her hand brushed his erection, and he moaned around the pacifier, hips lifting involuntarily.
The sex that followed was slow, psychological, wrapped in the layers of his regression. She had him on his back, diaper open, her mouth exploring the sensitive skin she'd just cleaned. Every lick and suck built on the helplessness—the way the open diaper framed his cock like an offering, the way she praised him in soft, maternal tones that made his mind float younger. "Such a good boy," she murmured, taking him deep, and the words unraveled something inside him. He came hard, the orgasm prolonged by the lingering warmth of a fresh wetting, his body shuddering as she swallowed and then taped him back up, the fresh diaper hugging the mess of release and powder.
Over weeks, the regression deepened. Mark began wearing during the day, thin trainers under his clothes at first, then full diapers when Lena encouraged it. The psychological thrill came from the risk—the lecture hall where he felt the first trickle, the way he had to concentrate on not squirming as the warmth spread. At night she visited more often, feeding him from a bottle while he nursed, her free hand stroking him through the swelling plastic until he was leaking pre-cum and begging in broken, little-boy whimpers. The sex was never rushed; it was the buildup that aroused her too—the sight of him crawling across the floor in just a diaper and onesie, the way his eyes went glassy when she pulled the tapes loose and exposed him.
One rainy weekend, the regression peaked. She had him in a full nursery setup she'd smuggled in: a changing mat on the floor, a stack of thick diapers, lotion and powder lined up like ritual tools. Mark lay there, pacifier in place, as she massaged him thoroughly, fingers slick with lotion sliding between his cheeks, teasing his hole until he was rocking back, desperate. She entered him slowly with a strap-on, the pressure combining with the full, wet diaper beneath him to create a sensation that blurred every boundary. He came untouched, the orgasm ripped from somewhere deep and infantile, his body convulsing as she whispered how proud she was of her college boy for letting go so completely.
Afterward, cleaned and repadded, Mark felt the satisfaction settle like a warm blanket. The academic pressure hadn't vanished, but it no longer owned him. The diapers, the regression, Lena's care—they were his release, a private world where adulthood could pause and he could simply be. He drifted to sleep in her arms, the crinkle of his diaper the only sound, content in the knowledge that tomorrow he would wake and choose it again.
