How it started

My first experience with female undies was when I was about 12...there was a bonfire being built in the field next to the woods near our house..mum asked me to take a bag of stuff over and put it among the other stuff being piled up...but said"make sure its well hidden in the middle" ..obviously being a typical nosey teen this made me curious what was in the bag....when I got to the bonfire I tipped out the bag..it contained some old clothes..but deeper down....some of mums old underwear...bingo!!! ..I gathered them up 2 bras,1 suspenderbelt 2 pairs of stockings....and a couple of pairs of knickers...suddenly I had a little tingly feeling down below...I stuffed the goodies in my jumper and headed to the woods..my heart was beating hard and fast...I headed into an area deep in the woods w here no one could see...I started looking at them closely..the bras were quite large and lacy ..I could remember seeing her wearing similar ones when she was changing and seeing her dark nipples showing through...the suspender belt I had never seen her wear but held it up and Sussed out how it worked....the stockings felt silky and nice to touch...the knickers...different kinds 1 cotton 1silky stretchy material ...I could remember seeing her wear both types..and imagined her hairy pussy that I had glimpsed a few times by accident in them... I took my little cock out it was standing fully erect I looked down at it..and pulled the foreskin back till the head was exposed..it was wet with what I now know was pre cum...lol the cool air felt amazing..as I looked wondered how these things would feel against my cock.. first the bra ...nice but not soft...next the stockings...wow what a feeling...next the knickers 1st the cotton ..felt nice..2nd the silky type...amazing....I could see the pre cum leaking even more..I stripped off my trousers and pants...my heart was pounding..afraid of getting caught..but so excited I pulled the silky knickers on...obviously too big but felt amazing.followed by the sussy belt then the stockings and clipped them on my clock was pushing out the knickers and as I looked down at them I imagined mum wearing them and her hairy pussy ...without warning I suddenly felt dizzy and went weak at the knees..I could feel a throbbing from my balls...I looked down could see my cock twitching inside mums knickers I pulled the waistband out and looked in at my twitching cock Cumming in her knickers..it felt like it would never stop....I eventually did and the guilt set in my hard clock now shrunk and went soft..I stripped off.and wiped my cum covered cock and balls with the cotton ones ...looked a the the chum covered silky ones...got dressed and returned the goodies to the bag in the bonfire.....in bed at night I couldn't stop thinking about the fun I had.....so next day set off for a repeat session..when I got there and looked in the bag everything was there except the knickers....someone had obviously found them...I always wondered what they done with mums knickers..that had my cum in them
