During a scorching summer, Sayuri stays late in the gym to practice serving with Coach Umeda for an upcoming mothers' volleyball tournament. She may look modest, but this G-cup wife has a voracious appetite for both food and men. Umeda confesses that a tall woman once bullied him, and although he calls it trauma, Sayuri notices his cock react. The next day she summons him, asks whether this is what he really wanted, then sits on his face, steps on him, and taunts him until his erection swells. The encounter builds toward sweaty cowgirl riding, a crushing scissor-leg press, and creampie sex.
