[18+] Showing My Step-Sis That I Don't Have a Small Cock

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 off and my dick just keeps getting harder in her mouth. I fuck her right in the backyard until I fill her tight pussy up, she wasn't expecting it nor wanted it....
