Tall, slender 170-cm beauty Mayumi Hamada appears in skin-tight running leggings. Seeing her stretch by the roadside ignites the narrator's desire, so he pretends to twist an ankle, borrows her shoulder, lures the helpful woman into his room, and attacks her. She says no, yet the leggings covering her bare pussy are already soaked. The smell of post-run sweat and breasts spilling from the sportswear intensify the fetish-heavy assault.
