my first sniff I was 13, my older sister was 17 and played a lot of sport. she wasnt home often as she spent a lot of time with her female sprt friends.
I had gone to shower and have a rub and on the floor was a pile of her clothes. Sitting on top were here panties, dirty crotch facing up. I couldnt resist i sniffed then licked and sucked and was suprised by how hard i got. I had a 30 minute shower just sniffing and rubbing my cock.
I have sniffed every opportunity i receive since that day.
