She made me wear the thickest diaper she could find, the one that crinkled loud enough to hear across the room. It was white, plastic-backed, and it sagged heavy between my legs the second she taped it on. "You're not a man tonight," she said, voice flat and mean. "You're my pissy little baby. And everyone at the party is going to know it."
I tried to argue but she shoved a pacifier in my mouth and pulled the strap of the onesie tight between my ass cheeks. The fabric stretched over the bulging diaper, making the outline obvious. My cock was already half-hard from the humiliation, trapped against the padded front, rubbing every time I moved. She noticed and laughed. "Look at that pathetic bulge. You're getting off on this already, aren't you?"
We drove to the bar. Every bump in the road pressed the diaper against me.
By the time we parked I needed to piss. She knew it. She reached over and squeezed the front of my crotch hard. "Hold it until I say. If you leak before then, I'll make you change in the parking lot with the door open."
Inside the bar it was loud, crowded, and every step made the diaper rustle. People stared. A couple of guys at the bar pointed and smirked. She ordered me a drink but made me sip it through a bottle with a nipple. "Drink up, baby. I want that diaper full." My face burned. I could feel the stares on my padded ass as I waddled to the table.
She sat me down and immediately started telling the group what I was wearing. "He's in a diaper because he can't control himself," she announced, loud enough for the next table to hear. "Watch this." She pressed her hand between my legs and I felt the first leak escape. Warm piss spread across the padding, soaking into the gel, making it swell. The wet heat wrapped around my balls and cock. I groaned around the pacifier.
"See? Already wetting himself like a fucking toddler." She pulled the onesie aside so they could see the yellow stain spreading up the front. My cock twitched and started to stiffen more inside the soggy mess. She rubbed the outside of the diaper, squishing the piss around my shaft. "He's hard from the shame. Look how it tents the wet plastic."
One of her friends leaned in. "Make him stand up and show everyone." I had no choice. I stood, diaper sagging, front dark with piss, the outline of my erection obvious. People laughed, phones came out. She made me turn around so they could see how the seat was bulging and stained. Then she slipped her hand down the back, fingers sliding under the leg cuff to check how wet I was. Two fingers pushed against my hole. "Still dry back here. Not for long."
She ordered another bottle for me and made me chug it while standing there. The pressure built fast. I started leaking again, a steady stream this time, soaking the diaper until it hung heavy and warm between my thighs. Piss ran down my leg a little and she pointed it out. "He's dripping on the floor like an animal. Someone get a mop."
By the time we left I was soaked, the diaper so full it leaked with every step. She didn't let me change in the car. Instead she pulled into a gas station and made me stand at the pump while she went inside. Cars drove by. People could see the wet stain down my leg and the obvious diaper bulge. When she came back she had a fresh diaper and wipes. "Change right here. Door open. Bend over so they see your messy ass."
I did it. The cold air hit my wet skin as I peeled the tapes open. The heavy, piss-soaked diaper dropped to the pavement with a wet slap. She wiped me roughly, front and back, making sure the wipes grazed my hole and balls. Then she powdered me thick, the white dust clinging to my skin, and taped the new diaper on tight. My cock was rock hard now. She noticed and stroked it through the fresh padding until I was panting.
"Get in the back seat. On your hands and knees." She climbed in after me, pulled the onesie up, and started spanking the padded ass. Each slap made the diaper squish. Then she reached underneath and rubbed my cock through the plastic until I came, shooting into the clean padding, adding another wet mess to the humiliation. She left me like that the whole drive home, ass in the air, fresh diaper already starting to smell like cum and powder.
When we got home she made me crawl. The new diaper crinkled with every move. She sat on the couch and pointed to the floor between her feet. "Show me how grateful you are for your humiliating diaper stories." I buried my face between her thighs while she stroked the back of my head, still calling me her pissy baby, still reminding me how everyone had seen me wet and exposed. I licked until she came, and the whole time the heavy, warm diaper kept me hard and aching for the next round.
