Three hot women crammed into the back room of the club after hours, all of them already half naked and horny as hell. Mia, the tall redhead with the tight abs, pulled the air pump out of her bag and waved it like a prize. "Who's getting pumped first?" she asked, voice low and filthy.
Lila stripped off her thong and spread out on the couch, legs open. "Me. Fill me up till my belly looks pregnant and tight." She rubbed her flat stomach, daring the others. Jenna, the curvy brunette, dropped between Lila's thighs and started licking her pussy while Mia attached the hose to a slim nozzle.
Mia worked the nozzle into Lila's ass slowly, then started pumping. Each squeeze sent air rushing inside. Lila moaned loud and dirty, her belly starting to rise and round out. "Fuck yes, more. Make it bigger." Her skin stretched smooth and shiny as air packed into her guts. Jenna kept eating her out, tongue flicking her clit while Lila's stomach grew rounder and firmer under her hands.
By the time Mia had given twenty pumps, Lila's belly was a swollen dome, tight as a drum. She looked obscene and sexy as hell, all that air making her look knocked up and desperate. "Touch it," she begged. Jenna pressed both palms flat on the bloated surface and pushed. Lila gasped, the pressure sending sparks straight to her cunt. "Harder. I want to feel it."
Mia took over the pump and kept going. Lila's belly kept inflating, growing heavier and rounder with every stroke. Her navel popped out into a tight little knot. Sweat ran down the curve of it. Jenna climbed up and straddled Lila's face, grinding her wet pussy on Lila's tongue while she reached down to slap the swollen belly. The sound was solid and loud. Lila came hard, thighs shaking, belly wobbling from the force of her orgasm.
They switched. Jenna wanted the hose next. She got on all fours, ass up, and Mia slid the nozzle into her pussy this time. "Pussy inflation feels dirtier," Jenna said, already panting. Mia pumped slow and steady. Jenna's lower belly started to swell first, then the pressure spread upward. Her stomach pushed out between her spread thighs, growing round and heavy. Every pump made her moan like a whore.
Mia kept working the pump while Lila fingered Jenna's stretched pussy around the hose. "Look at that gut," Lila said, voice raw. "So fucking full. You look like you're about to burst." Jenna's belly was huge now, shiny and tight, hanging low and taut. She reached down and rubbed it herself, fingers tracing the new curve. "Don't stop. I want it bigger. Make my belly huge and fuck me while it's full."
Mia pulled the hose out and replaced it with her fingers, then her whole hand. Jenna was so stretched inside that fisting her was easy. Lila climbed behind Mia and started pumping air into Mia's ass while Mia worked Jenna. Soon all three women had round, inflated bellies, touching and rubbing each other, the air making every movement feel intense and heavy.
They fucked like that for hours. Bellies slapping together, air shifting inside with every thrust. Mia rode Jenna's strap-on while her own inflated gut bounced and jiggled. Lila sat on Jenna's face and ground down, her swollen belly resting on Jenna's even bigger one. The pressure built until someone had to let a little air out with a long, obscene hiss, then they pumped each other back up again.

By the end, all three were wrecked and satisfied, bellies still round and tight, skin marked with red handprints. They lay tangled together, hands lazily rubbing the inflated curves, already talking about next time and how much bigger they could get.
