After a successful shoot in a famous hot-spring town, the cast and crew return to their inn for a wrap party. A demanding director, female and male performers, and staff—12 people in all—soon end up drenched in sexual fluids and tangled together in a huge orgy. It starts with a king's game, moves into condomless sex in the hot spring, and erupts into a full-scale twelve-person fuckfest. The scorching group-sex scenes feature big and small tits, youthful-looking adult performers, dominant women, and squirting pussies. Provided for streaming by Dream Room: Kareha Jijii.
