Because of my older sister all my adult life i've had an upskirt and panty fetish, It started when i was ten and she was thirteen, One day she caught me looking up her skirt as she sat carelessly on the sofa, She snapped her legs shut and went to her room, After that she would regularly tease me by opening her legs and flashing her panties at me even outdoors she'd squat by me as i played giving me a quick view up her skirt, Her favourite was to sit in a chair with her ankle on her knee as i looked, One day our parents were in the garden and she came up to me and put her skirt over my head ground her panty covered pussy into my face and said "sniff it dirty boy" and i did it smelled wonderful to me and as quick as she did it she stopped skipping off into the garden, She loved playing with her new power over me and knew i would'nt say anything to our parents, As we got older she took to sneaking into my room and lifting her nightie showing off her panties to me i would get hard and then she'd leave, Only once did she stay when i was fifteen and watched as i masturbated as she put her panty covered pussy close to my face so i could smell her, Ever since i've collected images of upskirts and panty shots and before i fuck a woman i have to lick and sniff her through her panties in particular if they are white panties as they remind me of my teasing sister, We have spoken about it since and she's pleased she gave me a fetish and has continued on occasion to flash her panties at me to this day in fact she did it yesterday she is such a bad girl, We have discussed having sex but she says maybe one day she might i dont know if she will but i wont complain if she does after all these years.
