>>2499457OP here. Good question. Never really thought about it. The 'more real' part probably has something to do with it.
But also, I went to grade school / high school in a small town with literally all Mormon girls in my grade (I'm not Mormon) who showed no skin, ever, and my puberty years were juuust before internet porn was readily available, so all I had in my spank bank for the most part when I was like 14 was the few girls who happened to wear short enough tee shirts that I'd get to see their stomachs in gym class when they'd play volleyball or whatever. A couple of them were pretty hairy chicks, and Mormon girls aren't self-aware enough about their sexuality to shave at that age, so that's probably where my fetish comes from.
On the same note I also have a major thing for girls bending down and showing buttcracks in jeans, probably because I can remember literally every one of those Mormon ass cracks I got lucky enough to see throughout my formative years when they would be bending down at their lockers or whatever.
Don't feel too bad for me though, I got to rail a couple of the hottest ones when we hit college and they decided to go 'wild' for like 2 months. Getting to lick the asshole of a girl who looked down on you for 12 years for not being her religion was a decent consolation prize for having had such a shitty high school life.
