I don't know why you think that her boobs are fake. Somehow you don't mention that she doesn't look her age, doesn't have wrinkles, dark circles under her eyes, or tonnes of make-up. Hot Milf has to have ugly boobs to have the only realistic thing about her. Right.
I mean, everything you listed can be changed a lot simpler in real life than the shape of her boobs. I also know people around her age that have none of what you said either, maybe wrinkling that is just covered by makeup, makeup you wouldn't even notice and therefore think is "no makeup".
Also again, they're ugly boobs in your opinion, man. People agree with you, but agree with me too. If you think the old ones were ugly? That's your perception buddy. Imho you shouldn't be finding boobs on the more natural side (but still porned up) "ugly", it doesn't bode well for being attracted to actual real boobs.
But you are forgetting that the main character in such games is not your typical neighbour mother of three (maybe sometimes). Her looks and her body are the reasons everyone around her wants her. I am personally against oversized plastic boobs too, but compared to what it was like before, now her boobs are heaven.
Also like your opinion my guy. I'm not getting any vibes people are purely going for her for the looks. Maybe I'm picking up stuff from the writing you're not, or maybe the writing is leaving enough for me to inject my own subtleties that give me that perception. I guess it's all porn anyway, but content I've seen that is purely "Wow wow you are hot lets bang" just doesn't do much for me, and the fact that this game does stuff to me means that there's more to it here.
It's great you think these boobs are heaven, I see these boobs as belonging to a very genetically gifted 18 year old, and my brain does not compute seeing them on an older looking woman without me getting "surgery" vibes. That's why to me they look fake all of a sudden.
Maybe if Wanda always had those boobs it wouldn't be so jarring? But I'd still think the same thing even if she started with them.
