In a deserted mountain village, the villagers worship Fukuman-sama, who appears once every 12 years, and is the only salvation in the midst of depopulation. Legend has it that if a villager's nighttime rape is successful, Fukuman-sama will be pleased and the village will prosper. At the instruction of the elders, it is decided that a nighttime rape will be carried out on Fukuman-sama's chosen busty bride, Iroha. The men are excited, vying to be the first to enjoy the village's biggest bust and her obscenely ripe body. As they roughly squeeze and suck on her busty breasts, Iroha's skin turns red with pleasure. Hoping for the prosperity of their descendants, they cover her busty breasts with the villagers' sperm, obscenely shake their asses, and cum violently.
