Waka is an athlete who belongs to the swimming club at her school. One summer vacation, the girl, who grew up in a single-parent household and is somewhat of a daddy's girl, is invited to her uncle's house who lives nearby and ends up staying for a long time. The girl, who is very interested in sex, is trained to have a dirty and sensitive body that suits the uncle's tastes... He devours the muscular and flexible body of the beautiful competitive swimmer and presses her with a large amount of seed. He injects a large amount of thick semen into her beautiful pussy. This is the problematic video of a middle-aged man who keeps cumming inside the girl during her summer vacation.
