I am 19 years old boy. I live in the part of South India.
To tell about my family, My father owns textile showroom and my mother helps my dad in the same showroom. My elder sister who is 21 years old has completed her under graduation and looks after household chores.
Our house has three large bedrooms in which both my parents use one room and me and my sister use the other two rooms.
It was weekend as usual me with my family had returned to house after finishing a night show at theater. As every weekend we all had our dinner and were off to our bedrooms for a sleep. Then as usual, I slept naked.
It was 1 o'clock night when I got up to pee. I opened my bedroom door and made sure no one was up and led towards toilet all the way naked passing our main hall and the kitchen and the toilet. Then I started to release my pee in my sleep hangover.
Then suddenly I was brought out from the sleep trance when I heard knock on the toilet door. I was totally naked without even a piece of cloth to cover myself. Then again I heard the knock and heard my sister yelling. I had no other way to escape other than opening the door, so I proceeded with opening the latch and finally opening the door covering my genitals with my hand.
My sister was shocked to see me naked and asked me why was I naked. I told her the things that happened. The time I was explaining I saw her eyes were still fixed on my Cock.
The way she saw my cock made me horny and my cock started getting life and was standing like flag post. When she saw my hard cock she yelled at me telling that she would complain this incident with mom and started going towards kitchen. I apologized to her, but she still continued her walk towards mom. I had no other option than getting hold of her. So I ran behind her and caught hold of her from behind and pleaded to her. She then slowly pushed her ass backwards by which I was aware that my cock was between her buttock cheek.
Then she told me that it was ok to sleep naked even I sleep naked but you should not get hard on by seeing your sister.
