The Spirit is Pregnant

Keigo was trying to get through his summer break without any romantic issues come up. However, during this summer, his uncle, involved in trading, returned home to Japan. He brings Keigo a charm: a small glass bottle, which contained a young, female water spirit, who he saves.
Separated from her home, the young spirit's very soul was on the verge of vanishing...and the only way to keep her soul from vanishing is to bear a child with a human being! Thus, she asks Keigo to impregnate her.
This is how Keigo came to live with a beautiful water spirit and have the very best (and very luckiest) summer of his life!

* A naive, big-breasted girl or a hot-cold beauty -- which will you live with?

The naive and big-breasted Fene not only loves having kids, but having sex as well -- she's willing to try anything once!
Then there's Chris, a haughty spirit who hates humans and strives to keep herself closed off, allowing sex o nly to preserve her life. If only she'd open her heart to you...

* Get your fill of co-habitation situations ans cosplay (costume play) sex!
Eyes-open fellatio, bubble-bath action, full-nudity except an apron hotness, school swimsuits, and all kinds of co-habitation sex in these outfits, situations, and more!

* Do spirits like having sex?!
Sex preserves their souls, feels good, and is a way of communicating with the main character -- these 3 factors combined mean that the spirits gradually become hooked on sex, and want more and more...! If you save up your cumshots successively, you can cover them in cum!
