This time, the person with a critical hormone deficiency requiring daily semen injections is you! Will you let your futanari step-sister fill your guts with her medically-prescribed jizz every day? The ongoing adventures continue as Momoe takes you to the doctor's office after you were starting to feel lethargic and fatigued. After some tests, the doctor came back with some bad news: you're suffering from an incredibly rare hormonal deficiency that has only one known treatment: daily semen "injections", typically taken vaginally or rectally, but oral route also works.

There are donors at the clinic, but you'll need to commute daily, taking hours out of your day. Plus, the treatment is pretty expensive. Without treatment, you'll eventually experience further fatigue, reduced movement and appetite, then organ shutdown and death. So it's either daily trips to the treatment center, or find a source closer to home. Say... why is Momoe looking at Sachiko like that?
