Stealing Panties from Clothes Lines

I some times find it arousing to go out at night walking along the streets to find a clothesline nearby to see if it has female or male underwear like briefs and panties, sometimes bras. I jump the fences or just walk around and take them off the clothesline and stuff them down my front crotch. I either go back home or to a public toilet with lights to see what sort of undies they are and sniff them, giving me an arousal like no other. I then proceed to take my pants off, then my top, leave my undies on, lie down with the crotch of the panties/undies in my mouth or sniff them. As a pull my undies down to my knees I move up and down on the grass/concrete/mattress. While doing that to the underwear I stole, I cum and put my undies back on and pants. I either throw the underwear away or keep it for further masturbation at home. I used to have heaps of female underwear I stole from my step mom and my sister even. Just the touch and smell of the crotch gets me hard. I used to have at least 100 pairs of female underwear, ranging from small to extra large. I used to masturbate while wearing my foster mum's underwear and camisole slips. I even dress completely up in her clothes and masturbated. She caught me once by finding her own bras and panties under my mattress. I denied I put them there... Enough for now.
