During a five-day holiday trip, Matsuri's sister who lives nearby leaves her son (Matsuri's nephew) with Matsuri. Initially, the nephew innocently touches Matsuri's breasts. The prank escalates, and eventually, he has sex with her in the middle of the night! Furthermore, the nephew calls his friends, and they proceed with "sucking tits," "cum shooting contest," "squeezing dick between tits to piss," and "taking turns inserting." They brutally assault Matsuri's voluptuous body as if it were a toy! This is a vicious shota gangbang work!
