IIN that i like to have my buns rubbed up against?

i get turned on when my naked butt touches an object, like out doors, a brick wall or something like that..... Your comment gave me a flash back years ago , i was in k mart with sweat pants on with no underwear, i saw a young lady (adult) in the check out with a nice ass! I got an erection and pretended to have to squeeze behind her to get by her with my bulge rubbing her ass! It was such a thrill i think i came afterwards!
