Nude photos of my own sister
I am 26 male. My own sister is 24. She is very introvert from childhood, doesnt talk with friends also sometimes but very good girl since i know her mentality.
After her degree she used to go for training classes for job purpose. There she met one guy and they became friends and it went till physical relationship with my sister, but no love between them. These things i got to know completely when i checked her gmail recently. They used to chat in gmail not in WApp or some other media.
One thing I was shocked is she sent her nude breasts pictures... Unfortunately I saw those pictures.
As a brother I feel difficult to see her in that way.
Later I questioned her personally in WApp. She agreed that she did mistake for some desires and told she didnt go for sex, just romance only happened and she pleaded to not reveal this secret and chat was ended. Now she wants to forget and doesnt want to make this mistake again. Only me and my sister know about this incident, my parents have strong belief on her compared to me that she never would make a mistake.
Now the problem is with my mind... After seeing, her naked pics are not going from my mind... I got lust feelings on her?
How to control this? I know this is not healthy becoz she is my own sister. But I used to imagine those pics, started jerking off every time... Please, give suggestions.
