Nearly ten years after becoming a sensation as a short-haired newcomer, Ai Mukai celebrates her anniversary as a mature, alluring beauty. With no script, director, or crew, she takes a private two-day hot-spring trip with just one partner. The coastal drive, shy embraces by the sea, tipsy kisses, and completely unguarded passion reveal a rare side of her. Forgetting the cameras, they repeatedly lose themselves in raw sex and creampies in an intimate travel documentary.
