Peeped while my Sister masturbated
We had the outdoor bathroom door worn out at the lower part due excess water falling on the wooden panel. In a standing position any one could see the leg portion from a distance. One day only my younger sister who is two year young than me and myself of 20 years old were alone as others where out. In evening I got up from my sleep and was moving around and heard my young sister bathing and running water sound. As I casually looked through the crack of the door I could see that she was sitting on her heels. I could see her side butts round and water sprinkling around her butts and heels. Just out of curiosity I just kneeled down and peered to see what is going on. To my utter surprise my young 18 year old sister fully nude was sitting close to the bath room wall under the running tap with the water directly falling on to her wide spread pussy which she had kept wide with her two fingers. The other hand was held on to the tap to balance her on her heels. She at times took her hand off her pussy to massage her boobs. Then she started to tremble and I knew she is going to have a climax. She further thrusted her clitoris to the water flow and she retreated numb with the climax. At that moment my sister noticed my palm flat on the floor in her sitting position and I think she saw my chin also. She immediately stood and shouted at me saying I am your sister bathing, go away. Embarrassed I backed out, went to my room and started masturbating. And as I was about cum my sister was at the door with an angry look. She muttered something and as I raised my head I started cumming in loads shooting at my sister who in utter surprise was horrified to such act and stormed out of the room. Felt embarrassed and worried whether she will spell it out to any one. Now I am unable to look straight into her eyes.
