Womb's Unexpected Guest

The apartment door slammed shut with a weary thud as Aunt Mara lumbered in from her shift at the dairy co-op. Her thick hucow frame, all curves and heavy udders, glistened with sweat under the dim lights. At twenty-two, I was nowhere to be seen—my two-foot stature made hiding easy, but she always found me eventually. 'Little troublemaker, where'd you scurry off to this time?' she called out, her voice a husky mix of annoyance and amusement. 'Don't make me tear this place apart looking for you.' She kicked off her boots, rolling her shoulders. 'Work was hell today. These swollen girls need to breathe.' With a sigh, she peeled off her top, freeing her massive, aching breasts. Her nipples hardened in the cool air. 'Feels good to let it all out,' she muttered, shimmying out of her skirt and panties next. Her pussy lips, already damp from the day's heat, parted slightly as she stretched. 'If you're spying, you little perv, enjoy the show.' She chuckled, witty even in exhaustion. 'Not like you'd know what to do with a real woman anyway—too pint-sized for that cock of yours to matter.' Mara sank onto the couch, her thick ass spreading wide. But she misjudged the angle. I was right there, frozen in shock on the cushion. Her weight descended, and suddenly I was sliding—my head pressing against her wet, dripping pussy. 'What the—?' she gasped, feeling the intrusion. Her body reacted on instinct, horny from the long day, and with a slick pull, I was drawn deeper. Her walls clenched, hot and pulsing, sucking me up her vagina inch by inch. 'Oh fuck, what's happening?' she panted, hands gripping the cushions. My small body, hard and squirming, pushed further until I slipped fully inside, her cervix yielding in a rush of pleasure. Her belly swelled instantly, ballooning outward with me trapped in her womb. 'This can't be real,' she moaned, sweating as her hands roamed the new, massive curve. The sensation was electric—every squirm from me sent waves through her core. 'You're... inside me? You little shit, this is insane!' She tried to stand, but her giant shaking belly made it impossible without wobbling. 'The other hucows can't see this. They'd never let me live it down.' Her pussy throbbed, dripping cum from the unexpected climax. 'Feels... too good though. Your cock must be twitching in there.' She laughed breathlessly, witty despite the shock. 'Bet you didn't plan on becoming my secret passenger.' As she hid behind the counter, belly quivering, a deeper pull began, promising more days of this forbidden intimacy. 'Don't you dare stop squirming now.'
