Sack Explosive Magical Growth – Transformation Fetish, Growth Fetish, Stuck Fetish

Tonight’s kinky antiquities auction was a bust… every relic sold for thousands. Broke, bratty and bored, I watch the final lot roll out, a filthy, tattered, white burlap sack the size of a bean-bag chair. No bids. Laughter. Perfect. I dropped My last twenty and drag the stinky thing home, feeling like an idiot. Alone in My apartment I flop on top of it to sulk… then slither inside just for laughs. The moment My head pokes through the drawstring collar, the weave snaps shut around My shoulders. A pulse of heat floods My limbs. I shriek as the coarse fabric sucks against every curve, sealing Me in total darkness. That heat turns molten. My spine stretches, bare feet push against the far end of the sack. Calves thicken. Quads balloon. Ass swells into two round, quivering moons that press the seams. My tits surge forward, nipples rock-hard, scraping the rough burlap until it frays. I feel My clit swell, pussy lips throbbing against the tightening cloth. The sack groans. I keep growing. fif
