Taichi returns home for a family gathering, brought by his mother. However, his mother's true intention is to set him up with his aunts, Yuka and Saki. That night, fate brings them to sleep side-by-side, and Taichi, seeing their disheveled and vulnerable postures, can't resist. Instead of getting angry, they notice him and, with mischievous smiles, start groping his crotch without mercy. Taichi, relentlessly tormented, is made to squirt repeatedly as the two aunts release their pent-up desires, leaving him drenched in sweat.
