I have been masturbating ever since I was 13 years old. One summer, my sister and I were home by ourselves everyday from about 8 a.m. to 6 p.m. I was 14 years old and my sister was two years older than me, which was 16. She had a nice developed body and a nice figure. I had a nice figure but I was still developing.
It was one day in July when it was hot outside. So we were inside minding our own business. I was watching t.v. downstairs and she was doing something in her room or whatever. It was about time when I would eat lunch, so I grabbed something to eat and headed to my room. Our house was arranged that in order to go to my room you had to pass my sister's room. I went to my room and put my food down and then went to my sister's room to ask her if she wanted me to get her something to eat.
So I walked into her room and she did not notice me. She was laying on her bed facing the opposite direction, with her pants to her knees. I was stunned and just stood there. I was getting wetter and wetter. After about 15 seconds of me watching her she turned around and saw me and started yelling at me. She pulled up her pants and told me to get out. After she yelled at me I went back to my room and masturbated for about 1 minute then I came. I was very horny.
We did not say anything to each other for about a week. Then one day she came up to me and said that she was glad she caught me and now she did not have to try to hide it. She asked me if I masturbated, but we never did anything together except the occasional walk in on someone. Thanks for reading.
