My Darling Amma and Sister _ Part 1

We are a family of four, Dad, Amma, Devi my sister and Dhar myself. We are very conserative telegu family living in Chennai. My mother is avery orthodox lady with old beliefs, it was like sister and brother cant hug, nor mother and son. I was 13 years old then, my sister was 9 and Amma was 38 yrs. I was curious to know why she was not allowing male and female to touch or hug.
I watch a lot of movies and i used to hire tapes from the local library, once one of the tapes i borrowed turned out to be a blue film by chance. That was the first time i saw or heard the word sex, naked women and men fucking them. I was 15 by then. From then on I used to get a hard on when ever i saw Amma or Devi my sister. I used to masturbate in my bedroom putting my Amma Saree and pettycoat, bra and blouse., Amma was 5.3 in height, she had huge boobs, may be 40, jetting out from the side of her saree , she had a nice round body.

I started to feel my sister private parts when she was sleeping. She used to sleep with her school dress most of the time. I used to go sleep next to her , start by giving akiss on her lips, slowly touching her breast, by then my dick used to become very hard, i slowlu used to lift her skirt, move closely to her with my erection touching her vagina area, then i removed my shorts and shirt i used to sleep full nude on my sister and rub my dick on her vagina area with her panties on, and i used to come. This i used to do it very often, without any one knowing, by then i bacame 18, more like a grown up adult. I was 6.2 in height and 90 Kilos in weight and a dick when erected will be 10 inches.But my luck ran out very soon, one day in the afternoon i was kissing my sister in her sleep on her lips and putting my hand under her skirt and feeling her vagina area, my Amma just walked in to the room, and i jumped out of the bed, pulling my shirt down to cover my dick, beacause it was hard.
Amma asked what are you doing in this bedroom, and what are you doing with Devi’s
skirt, I said amma her skirt had come up, iwas only trying to put it back properly.. She said okay, but she never trusted me from then on, she would never allow me to come anywhere close to my sister, or even talk to her alone.
