Nearly 10 years after taking the world by storm as a short-haired girl, Mukai Ai has evolved into a beautiful, short-haired woman exuding mature sexiness. This is a project to celebrate her 10th anniversary since her debut. With no script, no director, and no staff, it's a two-day, one-night hot springs trip just the two of them. The drive date along the coast, the embarrassed embrace on the beach, and the drunken kisses with their faces exposed and wild are incredibly rare. A private creampie sex documentary in which they forget about the filming and indulge in raw sex over and over again.
