An ejaculation assistance service helps men who cannot get themselves off for unavoidable reasons. With an unemployed husband and a bedridden father depending on her, big-titted and fully shaved Kosaka Meguru has little choice but to take this unusual job. It is legitimate work, but from her husband's perspective she is still wrapping her hand around other men's cocks, so she keeps it secret from him until he eventually finds out. And if a client gets carried away, fucks her, and takes the service beyond simple assistance, that would be cheating. Her husband follows her and witnesses what happens. What fate awaits Meguru after her secret job is exposed?
