Younger sister and me

My younger sister was always my favorite. She was four years younger to me . Upto her age of 14 it was pure brother sister relationship. One day on the first floor of our home we were reading an article. My left hand was touching her boobs. They were extremely soft. But she did not try to avoid my touching. For the firstntime I started having sexual desires towards her. After a few days we were all alone at home. She was taking bath. Our bathroom was adjacent to the kitchen. Standing on the kitchen platform one could clearly see inside the bathroom. She was cleaning her hair under the tap. Her boobs were partially visible and thighs and buttocks fully visible. I was quite surprised to see her large boobs and fleshy thighs and buttocks. After ten minutes I got down. After that day when we were all alone at home I used to watch her whole shevwas bathing.After a few months since our father was away for one month three younger sister including the youngest one were sleeping in one room. I was in cot and they on a bedsheet on the floor adjacent to the cot.One midnight they all were fast asleep. I inserted my right palm into her petticoat. She was not wearing any bra. So I could touch her soft and reasonably large boobs. She didn't know about my naughty activities ( thats what I thought) Within one month at least ten nights I performed my activities. After five years she got married and I left the home to join my job. After that we had no contacts. I also got married and was staying in a house outside our district
