But when he goes to pick her up, the one who was supposed to be the driver is already tipsy. With no choice, he heads into her house like always to look after her. While helping out, an unexpected accident happens—the beer Sakura was drinking spills all over her body.
Beneath her soaked clothes, the outline of her swimsuit clearly shows through—
“Help me take these off, will you? The clothes.
I mean, you’re the one who made the mess, right?”
Sakura teases him with that daring command. Her damp body, combined with the sweltering midsummer heat, begins to chip away at Haruta’s self-control…
On this blazing summer day, inside a cramped six-tatami apartment, indulge in the secret, sweat-drenched passion Haruta shares with his cousin, the older sister figure he can’t resist.
