That's why in most games I'm willing to entertain the threesome arrangement, but anything past that is pretty much insanity. I'm not a very jealous sort of person, so Heidi/Athena doesn't bother me in the slightest - in fact, I'd say it's almost better than many other options, because those two clearly have an established relationship before MC comes along. In this kind of situation, it's less "Ha ha, I'm banging two women!", it's more "Hey, these two hot women like to borrow my funstick on occasion".
As a self-acknowledged weirdo with a bit of a breeder kink (despite hating children), most games I've played here from F95 have a character or two (or five) that I look at and think "Hey, yeah, she'd look good with a bun in the oven, let's see if that's possible". Strangely, I really don't get that feeling so far with any of the characters in Bare Witness. I like most of them, but I don't feel that urge towards any of them, because I'm still a selective breeding sort.
Athena is cute and all, but .. nah. Heidi is really nice and sweet, but also a little goofy looking. Mora? No. She's a geeky gaming girl, and while we definitely need more of those in the world, knocking her up is the quickest way to end regular game nights with the friends. And then there's Sadie. Despite being MC's cousin (and yes, I know it's a fantasy game), it's not the incesty factor that steers me way from her, it's her very clearly obsessive behavior.
If anybody was going to snap and take an axe to the MC in his sleep, it feels like it would be her. I worry she'll be the bunny boiler. HELL NO I ain't going to anchor myself to a woman like that.
Val/Zen/Nicole really just aren't on my radar for it at all, either, due to age or personality issues. That makes this game a really odd one for me. I'm enjoying it and definitely looking forward to more, even without it really pushing my buttons like several others do.
Now, if a couple of the girls get together and decide they want kids, the MC could be the donor for them ("direct deposit"), without it having to destroy his life. And if he's not a total idiot, might even be a part of their lives moving forward.
