I really like the direction this game is going. Characters are super sexy.
I have a small suggestion or wish to make:
It would be awesome if you could command Ruca to face the glass window in her room as you coerce her into letting you boop her from behind, with an over the shoulder view of people watching in shock from the adjacent building- This could either allude to her being an exhibitionist of sorts or simply blinded by lust. We could get a nice shot of her perfect breasts pressed against the glass, as an onlooker perspective.
Anyway, loving the game so far. Hope it gets worked on some more.
