My Sister's Friend

I'm disabled and I live with my mom and my sister. A few weeks ago my sister had a few of her friends over to spend the night. I'll call them C and W. I forget how old W is but C is 19. C is a very beautiful woman. C decided to color her hair and my sister helped her. C didn't want to get her shirt messy so she took it off and wrapped a towel around her chest.

I walked into the kitchen while my sister and C were in there. I saw the straps and the back of the black bra that C was wearing. My cock got harder than it had been in a long time. I went into the bathroom so I could jerk off. C aroused me so much that it only took about 30 seconds for me to shoot my cum into the toilet. I came so hard that my legs almost gave out.

Since then I've been trying to figure out a way to be able to see C nude. Every day since then I think about C and have really great jerk-off sessions.
