Most of the time, games have grannies that don't look like grannies. In this case, the models are sometimes attractive but seeing a granny who looks like a thirty-year-old breaks the immersion 🤷♂️
In games: not really, but if it's good implemented (models, story), why not
IRL: yes, especially in pantygirdles, vintage lingerie and / or corselettes
All right. Uh-huh. Let's define the terms. My spouse is 52 years old - is that a GILF or still a MILF to you? I consider her very young both mentally and physically.
My sister-in-law is 50 years old, but in stores, when she buys cigarettes or beer, she is asked for ID (she looks good and very young - the result of both good genetics and self-care). Is this a MILF?
