City Hunter (1987) : 2x43

Ryo runs into Kasumi Asoh, the "flying tush object" he met several years earlier. Kasumi is now 19 and is set to go into an arranged marriage in which she wants no part of. She thus masquerades Ryo as her lover, much to the disapproval of her grandmother, and Takeshi, Kasumi's arranged husband. Takeshi uses unscrupulous tricks against Ryo, by first hypnotizing him into believing that Takeshi's "mokkori" is bigger than Ryo's then when Ryo finds out about the hypnosis, hypnotizes Ryo in a state in which he can no longer experience "mokkori".
