Yuka Tachibana, a married woman who agreed to film a scene while pregnant, is immersed in the passionate penetration of another man's penis, her body drenched in sweat. (YSN-409)

Yuka, married for only a year, is a lewd wife who enjoys the looks of excited men. She usually flirts with men other than her husband, using her G-cup breasts to seduce them. She says, "Please forgive me. I already have a husband..." but her body obediently allows herself to be penetrated. She orgasms under the gaze of a face her husband has never seen before, and even being forced to have a child and ejaculate inside her makes her happily accept it.
