Mai-chan is a third-year university student from Kansai. Her "desire" is deep throating. She learned about the pleasure of deep throating from her first boyfriend. The shock has not worn off and she is still smoldering from the experience. Then she receives an offer to appear in an adult video out of the blue. Her round, Hitomi-like eyes sparkle as she accepts immediately. A rare genius, Arawal, overturns the common sense of the staff and male actors with his special deep throating, double orgasms from deep inside the uterus and deep throat, and orgasms from lack of oxygen caused by choking.
