I think you prudes got stuff mixed up. This is clearly not a porn game, since at worst you get to see nipples. You'll find more porn at the art museums over all countries than you'll ever find here.
This game is just eye candy or fan service. It has breasts and thighs as well as butts. When wearing underwear you'll look like the Victoria secrets magazine. I don't think that either counts as porn, but as selling clothes.
