Keita visits his long-awaited aunt, Saki. He greets her with a smile, but his eyes are glued to her chest. He realizes his aunt goes braless at home... Her breasts sway with every movement, their position and shape unmistakable. Keita tries to maintain his composure, but Saki, who never imagined her nephew would be attracted to her, falls asleep right there. The exposed nipples of her defenseless chest are right before his eyes. Keita can no longer resist the urge to play with Saki's nipples.
