You kneel on the thick changing mat, your cock already half-hard inside the crinkly diaper you begged for last night. She stands over you in nothing but a tight tank top and panties, holding the oversized pacifier in one hand and the bottle of warm milk in the other. "Open," she says, and you do, because that's what babies do. The rubber bulb slides between your lips and you suck without being told. The taste is sweet and fake, just like the baby role she's forcing on you tonight.
She tapes the diaper tighter around your waist, pressing the front down so the bulge of your erection shows through the plastic. "Look at you," she says, voice low and filthy. "Big man turned into a diaper-shitting baby. You wanted this. You asked for it." Her fingers trace the leg gathers, making sure everything is sealed in. Then she pushes your shoulders back until you're lying flat, legs spread like the helpless infant she's turning you into.
The pacifier bobs as you suck harder. She climbs over you, knees on either side of your chest, and lowers her ass just above your face. "Smell what you're going to make," she orders. The scent of her own earlier mess still clings faintly to her skin. Your cock twitches hard against the diaper padding.
She laughs, low and dirty. "That's right. Get excited about it. You're going to fill this diaper like a good little baby."
She sits back, grinding her pussy against the front of your diaper, rubbing the plastic over your trapped cock. The friction is rough and perfect. You moan around the pacifier, the sound muffled and wet. She reaches down, slips a finger under the waistband, and pushes it against your hole. "Push for me," she says. "Make that mess you keep fantasizing about."
Your face burns, but your body obeys. You bear down, feeling the pressure build low in your gut. The pacifier helps; sucking on it keeps you small, keeps you in the role. She watches your face the whole time, eyes dark with arousal. "That's it. Let it out. Fill your diaper like the filthy baby you are."
The first log starts to push out, thick and hot, spreading against the padding right between your cheeks. You grunt around the pacifier, the sound babyish and involuntary. She grinds harder on your cock as the mess grows, the diaper sagging and warming under you. The smell rises fast, heavy and obscene. She moans, actually moans, and reaches down to press the front of the diaper against your straining cock, smearing the load a little as more comes out.
"Keep going," she demands. "Don't stop until it's full." Another push, another thick rush of shit, and the diaper is heavy now, the plastic bulging outward. Your cock is leaking pre-cum into the front, mixing with the warmth. She pulls the pacifier out just long enough to shove two fingers into your mouth. "Suck," she says. "Pretend it's my tit while you shit yourself."
You nurse on her fingers, tongue working, while the last of the mess forces its way out. The diaper is ruined, sagging between your legs, the load pressing up against your balls and cock. She pulls her fingers free, wipes them on your cheek, and replaces the pacifier. Then she slides down your body, straddles your thighs, and starts rubbing the front of the loaded diaper in firm circles.
The sensation is overwhelming. The warm, squishy mess shifts with every stroke, pressing against your hole and your cock at the same time. She leans in close, voice raw. "You came here wanting to be turned into a baby. Now look at you. Diaper full of your own shit, pacifier in your mouth, and you're about to cum like the pathetic little mess you are."
Your hips jerk up into her hand. The pacifier slips halfway out as you gasp, but she pushes it back in with two fingers, holding it there while she works the diaper faster. The orgasm hits hard and sudden, your cock pulsing thick ropes into the already filthy padding. She keeps rubbing through it, milking every twitch until you're shaking and whimpering around the rubber.
Only then does she stop. She peels the tapes open slowly, letting the heavy, stinking load flop out between your legs. The smell is stronger now, and she inhales it like it's perfume. "Good baby," she whispers, almost tender for a second. "Next time you'll do it on command with the pacifier clipped to your onesie."
She leaves you there on the mat, diaper open, pacifier still in your mouth, while she goes to run a bath. You lie still, sucking slowly, the taste of rubber and the heavy scent of your own mess keeping you deep in the role. Turned into exactly what you asked for.
