[Abubu] Unmarried young female traditionally have sex with a male relative on New Year's Day [Japanese, English]

Every New Year's Day the relatives gather at grandfather's countryside house, and busty young Hana — the family's only unmarried woman — carries on a tradition that puts her lush, hairy body at the service of every male relative in turn. Her elderly uncle savors her enormous breasts before claiming her first, and the uncles and older cousins follow one after another while the rest of the family listens from the next room. By night the sake flows and the old men grow bold, but Hana's duty isn't finished until little Ryota is brought to her futon, eager to prove even the youngest cousin has a place in the family tradition.
