I'm not completely certain, since I've had the MC be a manwhore throughout, but I know there are at least some things that are optional. Maybe someone else has limited who the MC is with and could speak more to that. But it might be possible to limit interactions. For example, I know there are
some times when Sandra watches but doesn't interact physically with the other woman present. But I have no idea if that's a consistent thing that could be managed. The developer,
Nefastus, is on F95Zone, so you might wait for him to get on at some point again (last seen about 11 days ago) to definitively tell you what's possible if no one else knows before then.
