Tsukasa Aoi is undergoing special training to acquire forty-eight moves in a certain idol-style costume. Tsukasa-chan shakes her hips while the actors perform their skills and lead them. Every time the technique changes, it is pierced with a hard piston. At the missionary position, first press the piston to the back of the insertion part. In addition, a high-speed & hard piston is struck to the back, and at the end, semen is shot on the face. After the cleaning fellatio, it was Tsukasa who was in a state of daze.
