Kamikakushi no Eden - Vol. 1 Ch. 3 - In Spring, The Peach Blossoms Bloom

[Amenohi]

Really like Shirai a lot. A good combination of blunt inconsideration and teasing.
Watching Momoka do it was kinda awkward. Especially since she told her to watch quietly before giving Hinata a blowjob.

Bro that's a violation. 💀💀

 

[EmVoid]

Did they just did it without foreplay?

 

[LARGames]

God damn it. If only she was flat. This would be amazing....

Of course they are related... can't have a Japanese harem story without a relative...

Still, damn they are moving fast. MC also took the invitation of his cousin for babymaking almost immediately. Wouldn't hurt to at least plan ahead a bit for the future. In the other series of the author the MC was at least a bit mindful of family planning.
