She was eight months gone and her belly was huge, round and tight, sitting high on her frame. I walked into the bedroom and she was already naked on the bed, legs spread wide, one hand rubbing slow circles over her swollen clit while the other squeezed a leaking nipple. Milk beaded up and ran down the side of her tit. "Get over here and fuck me," she said, voice low and rough. "I need that cock stretching my pregnant cunt right now."
I dropped my pants and climbed on.

No teasing, no slow build. I lined up and shoved straight in. She was soaked, hot, and her pussy gripped me like it was starving. Her belly pressed against my stomach, firm and warm, rocking with every thrust. "Harder," she grunted. "Don't hold back just because I'm carrying. Pound this pregnant hole."
I slammed into her, balls slapping her ass, watching her belly jiggle and her tits bounce. Milk sprayed a little with each hard drive. She grabbed my hips and pulled me deeper, moaning filthy shit about how good it felt to get fucked while knocked up. When she came she squeezed down so tight I almost lost it, her walls pulsing around my shaft.
After I filled her she didn't even let me pull out. She rolled onto her side, belly resting on the mattress, and reached back to spread her ass. "Now do the other hole. I want both my pregnant fuckholes used tonight." I pulled out of her dripping cunt and pushed into her ass. It was tighter, hotter, and she pushed back against me, taking every inch while she rubbed her clit again. "That's it, stretch my pregnant ass. Fill it up too."
We kept going like that for hours, switching positions, her belly always in the way but never slowing us down. She rode me reverse, leaning back so I could watch her swollen stomach and leaking tits while she ground down. She talked nonstop, dirty and direct: "Look at this big belly. You did this. Now fuck the mother of your kid like the slut she is."
Later her friend showed up, also pregnant, belly just as big, and the two of them got on all fours side by side. I took turns driving into each of them, comparing how their pregnant pussies felt, how their milk tasted, how they begged for cum. They kissed each other while I fucked them, hands roaming over each other's bellies and tits, swapping spit and moans.
By the end both were leaking cum from every hole, bellies shiny with sweat, tits dripping. They lay there panting, rubbing their swollen stomachs and smiling like they'd just won something. "Same time next week," the first one said, already fingering the mess between her legs. "Bring more friends if you want. Plenty of hot pregnant pussy to go around."
