Incest Tag

While a good chunk of the Eroge is Ryouta losing his shit over his "best friend" Nagi railing his mom Riho behind his father's back untill she gets pregnant, Ryouta can grow into a voyeur cuck who starts enjoying seeing his mom taken away, and there's the route-end option of Ryouta joining in Nagi and Riho's debauchery, thus incest.

It's kind of similar to some of the previous work.
When the mc finds out his mother is pregnant.
It would have been nice to have another route where the mc impregnates his mother.
