Confined with Goddesses v0.2.5 Win/Mac/Android by ERONIVERSE - Adult Sex Game

Overview:
Confined with Goddesses is a light-hearted story based on hentai culture, in its "funny" aspect. My inspiration is coming from hentai/manga, adult manhwas, and few adult games I like.
The mc has a girlfriend, but isn't thinking about cheating. Even tho' he knows they're able to get him hard very easily, they all already are in couple so... "no danger".
Mc's goal: He's surrounded by 4 girls, it's a good opportunity to try to understand how to please a woman, by "discussing and observing" them, in the hope of being a better friend.
