Panty Fetish Begins

So much happened when I was 15. That was also the year I started my near lifelong panty fetish. My mate had asked me to feed and walk their dog for the weekend as he and his family were going away for the weekend. The first time round there after feeding her and letting her out I was in his mother's room. I stripped off and was turned on being naked in her bedroom that I couldn't believe how hard I was. I just had this idea to try some of her clothes on. I thought that I would have to be very careful as I didn't want to be found out. I went through her underwear first, fondling her knickers, imagining her in them and staring at the gussets knowing this was where her pussy went in them. I thought that I had better not try clean ones as I was scared I might cum in them so i went through her laundry basket and found myself with four pairs and three bras to choose from. As I went to try on the first pair I noticed the stains in them from her pussy. I don't know why but I just had to have a sniff. Well getting the scent of her pussy was all it took to get me hooked. I tried on all fours pairs and her bras. I felt so turned on and for me had a massive erection. I wanked and came in the most stained ones and came where her pussy had been. I managed to get them dry and put them back after checking there was no sign of what I had done. All I had to do was think of her wearing them and I would get hard.
I was very worried after they got back that I would be found out but luckily I wasn't. After that, every opportunity I have had I have gone through women's underwear drawers and laundry baskets. It is still just as big a turn on now as it has ever been.
