The Iwatobi Swimming Club, after a long day of practice, finds themselves in the empty pool house. As they undress, the atmosphere shifts, charged with an unexpected tension. Two of the team's most talented swimmers, Haruka and Makoto, find themselves drawn to each other, their eyes lingering on the other's bare form. As they shower, Haruka's hand accidentally brushes against Makoto's cock, igniting a spark that leads to them exploring each other's bodies in the steamy shower.
