In a single-parent household with his father often away, Shota orders dinner every day through a delivery service. The delivery girl who shows up is unexpectedly a beautiful big-breasted woman who completely captures Shota's heart. Drawn in by her charm, he starts wishing for her to deliver again. Feeling lonely without a mother around, Shota invites the sweaty girl to join him in the bath. As they wash each other, his cock gradually hardens, and he starts seeking her touch. Boldly, he pretends it's accidental and inserts himself into her pussy. In reality, the girl is also working as a gravure model, quietly practicing for photo shoots while enjoying these naughty pranks. Their overnight stay leads to a highly energetic sex session with an exciting progression you won't want to miss.
