No, I won't add any NTR and sharing.
MC can have sex with married women from other houses, though (optional)
In threesome/foursome I meant that MC will have sex with multiple girls. FFM/FFFM... or FFF/FFFF if you play as a futa.
It's exactly what I was looking for to play, I'm going to download and play it right now, I liked the theme, it's hard to find a game like this with just women, without men getting in the way, I hope you do more and more
