Palworld - Friendly Battle

It's a holdover from the 20th century. Remember we didn't always have free on-demand porn, so that niche used to be filled by schlock movies, those directors would find ANY excuse to make women titillating for four minutes. If they couldn't get away with actual toplessness (Starship Troopers, The Big Boss) they'd put the women in white cotton shirts and find something wet to have them wrestle in (Mortal Kombat Annihilation)
