How it all started or me, true story

Like most boys I started masturbating when I was 12, 3 or 4 wanks until I finally shot my first real load laid on my bed thinking about a girl I had kissed at school that day,and that was me up and running,around this time I had started to notice my auntie Sal's tits i thought they were just amazing I couldn't get enough of looking at them at every opportunity I had,they and she became the main focus of my early teenage masturbation sessions.Then one night when her and my uncle were around at our house both our families decided we should go on Holiday abroad together,oh wonderful I was going to see her every day for 2 full weeks I couldn't wait,the time came the Holiday was brilliant and yes she went topless on the beach as did my mother, I pulled my young cock raw.A few weeks after they asked me to babysit my 2 cousins for them at their house, they gave me £5, the k**s were already in bed when we got to theirs and I sat down to watch TV, they all said their goodbyes and out they went.I decided to have a look around and went into the dining room and there before me were a neat pile of clothes topped off with one of her bras and what looked like some pairs of panties,I walked over and with my hand shaking picked up the black lace bra sure enough a matching pair of panties were underneath with a couple of pairs of similar white ones,I just stood there shaking, I looked for the label 36DD I could feel myself getting rather hard and breathless ,I put the bra down and picked up the panties they felt so nice so sexy, I started to imagine what my auntie looked like in them.I could take no more I put the panties back on the pile undid the zip on my trousers and dropped them to the floor taking my rock hard pulsating young cock out of my boy pants and started masturbating, I stopped and listened for quiet, all was silent in the house,I decided I needed to cum but I had to try these on I wanted to feel them and her on my cock,but not here I needed a locked door just incase,I grabbed the bra and panties and went to the downstairs toilet locked the door behind me and undressed fully, I stood there naked breathing heavily and shaking uncontrollably. I pulled the black panties on and up over my leaking raging hard cock end ,I was in heaven,next the bra I struggled for ages to fasten it but finally it was on ,all loose and baggy on me but I didn't care it felt amazing I felt amazing I grabbed my desperately wanting cock and shot my load all over the floor immediately wow!.I quickly cleaned myself and the floor up of my young wet load got dressed and placed the underwear back as tidy as I could,still shaking I went back to sit and watch the TV, thinking will there be another chance for me to do this again..... as it happens there were a few more times,but that's another story to tell.
