When I was about 11 or 12 I used to peep on my mother. My bedroom was opposite the stairs to the second floor where mum and dads room was and also my sisters. After I had gone to bed I could leave the door slightly open and hide in the darkness and watch my mother walk up the stairs after her bath. Sometime she would be naked which was a thrill but not as much as if she had knickers and a bra or even just her knickers. Never really knew why undies were more interesting than naked but they were.  Nothing sexy about them. Plain white bra and white 'big' knickers, but hey, I was 12...

 My sister always had a nightie on except for once when I caught her naked but i longed to catch her in her undies. She was 3 years older than me, well I guess she still is!, and one night as she passed the door she suddenly turned in and opened it sending me scurrying for my bed. She became angry and accussed me of spying on her and threatened to tell on me so I had to admit it was mother I was looking for and then only to see her underwear. This was the start of a serious amount of teasing from my sister, teasing which was definately abuse but what became so pleasurable for me.

 She asked if I got off looking at our mother which I had to say I was confused about. I had used to get hard but hadnt discovered wanking quite that early. My hand was still a virgin. So she pulled the bedclothes back and felt my cock, well it was soft but instantly became hard. I was totally freaked out and both embarrassed and scared that my sister was touching me there but next night when she visited my room she sat on my bed deliberatly showing her panties and asked if I like looking at hers more than mothers. I must have blushed and stammered so she had to check under the bedclothes again. This time she managed to get my cock out of my pyjamas and laughed. I was somehow unable to move to cover myself up and she grabed my cock gently and started masterbating me. Wow that was so amazing and scary at the same time. I hadnt much time to enjoy it as a came and spurted all over the bedclothes. My first proper orgasm apart from a few wet dreams.  And that was the first of very many orgasms, a lot of them by (and in) my sister.
