Showing My Step-Sis That I Don't Have a Small Cock. I can not believe my Ex is talking all this trash about me after we broke, it even got back to my step-sister that I have a small dick. My step-sister Natalia starts to make fun of me accusing me of having a small dick, I can not take this from my step-sister, I pull out my dick to prove it. She must have really liked what she saw cause she wanted to see it..... in her mouth. Natalia starts to suck me ...
