[Kaiga] Rooms you have to fatten up to 1 ton to get out

Two schoolgirls discover a bizarre room where they must gain weight to reach a ton and escape, prompting a frantic, escalating feeding frenzy that transforms one into a massive, curvaceous figure while the other watches in shocked awe. As the weight climbs from 52 kg to over 3 ton, the once‑slim girl becomes a towering, fleshy mass, clutching a pipe as she begs to stay in the oppressive space, while her companion desperately tries to help and urges her to drink more. The climax shows the weight gauge exploding beyond 3 ton, leaving the characters trapped in an overwhelming, sensual struggle for freedom.
