One day, Shota goes on a business trip to the countryside with his boss, Sarina, to negotiate with a major client... However, there's a problem with the hotel reservation, and they end up sharing a room. Despite the awkward atmosphere, they have no choice but to spend the night together in the same bed... Sarina is a perfectionist and cool female boss at work, but when she drinks, she suddenly becomes bold and bold, a "gap girl." That day, after paying at the bar in the hotel, she attacks Shota. Shota, who has a girlfriend, resists, but his sadistic side stirs and he succumbs to Sarina's tongue skills. Her slender figure in black pantyhose and blonde gal appearance make his erection rise, and he ends up cumming inside her repeatedly on that forbidden night.
