This hentai is just one big giant tease. It has a lot of potential it didnt live up to. Ayano is a doctor who cant find a man. Her mother wants her to have a baby if she wants to take over the clinic. Taika is a man with erectile dysfunction. Who got dumped in the past for not being able to get it up. However with Ayano he is able to get an erection. So they make a deal. If he can get her pregnant they can get married. But so much more could have been done with this. Taika's coworker Mimi is interested in Taika. Shewants him to see her as a woman. And the story could have done more with a potential affair with a side girl.
They could have used Ayano's mom for an erotic cougar scene.
They could have brought back Taika's previous girlfriend as a jealous ex.

But the hentai just ends...
