As summer draws to a close, passions run higher than ever between the lovers. On the fourth night, with the end of their journey in mind, SATOSHI and TAIGA still crave more. Sneaking away unnoticed by the others, they meet in secret. At an empty observation deck bathed in the glow of the setting sun, their bodies entwine. Their sweet, intense, and deeply erotic connection deepens as each man's desires are fulfilled. Teasing and embracing, they push each other to the edge, merging their bodies in a final, unforgettable climax.
