I was 17 and just into my last year at school.
The girls at school were whaletailing like crazy every non uniform day. And once into 6th form it was non uniform, so thongs and strings were on show everyday from day one when a rather nice girl stepped over my leg to expose a white g string. 2 years of solid thong viewing. I really became a total thong freak over those years.
So looking at the girls strings all the time, thinking about that when doing 'whatever' at home, siting eterno-hard at back of class etc got me thinking about getting a thong. So I headed up to Selfridges on Bond St and went to the mens underwear bit and there was, at that time, a selection of mens thongs. I was a bit 'excited' at picking one, grabbed one in my size and went to pay. The attractive woman at the till took it out to check it and smiled, which really turned me on as a non sexed teen, and I paid. It was a HOM Bynight G-String, jet black/sparkly/metal HOM logo on front. Still have it as a memento, sadly the actual thong strap warped in the wash. Used to wear it to school and sit looking at the girl's whitetails with my cock stretching my own slinky string.
My final exam I was sat behind one of the two girls id fancied for years and she had a white thong on with little red ribbons, sat above her jeans all exam as i was sat rock hard writing an essay on Stalin lol, only exam i got 100 percent on. on the night we all went to celebrate i noticed the other girl i 'liked' had a little back g string with pink sides on, sadly it was just t back not a triangle but had a little pink bow on the T. I was drunk so i pointed it out and she said 'I'm sorry i hate it when they (jeans) sip down, I'm wearing really small pants today' so I , being both drunk and entirely erect, asked her for a pic. so she handed a guy the camera and he took a pic of us with the string poking out the front then when he handed me back the camera she pulled her jeans down slightly more, tapped me and told me to take a pic, turned around and stuck her tongue in a smile out for a rear shot. still got that pic, still 'enjoy' it lol. I was wearing the (joint) second thong I ever bought that night. It was an orange HOM string that came in a twinpack from Selfridges, with a black sister string, in a nice little box with a drawing of a man's butt in a g-string. So that little string was being stretched at the front as this was happening lol
