[Chinese]JUFE-143 I worked hard for a month to save up for my wife's pregnancy efforts... but my wife's sister, Megumi Kuromaru, who can't have sex with her own husband due to work reasons, steals my sperm using her erect-nippled, braless huge breasts.

Takashi and his wife, Kanon, have been married for two years. Wanting a child, they engaged in 'pregnancy preparation' by having Takashi abstain from sex for a month to produce healthy sperm during the fertile window before ovulation. On the other hand, Kanon's sister Megumi, who works as a flight attendant and travels frequently, struggles to conceive with her husband. Eager to have a child before her younger sister, Megumi visits Takashi on his planned conception day and seduces him, taking all of his accumulated sperm.
