man i hope i dont get flamed, but i realy dont like exposed thongs, i think they're tacky & too over the top ( pun intended). that being said, nothing turns me on more than seeing thong lines thru a womens clothing. i remember this one time i was in the local supermarket, this middle aged women, mildly attractive but average, bent down in front of me. i looked at her ass and there were her ample ass cheeks split by a thong, holy crap. i must have jerked it 20 times thinking of this nondiscript women , a mental image of her with her panties pushed aside, fingers sliding up & down her slit.
