Oh my God! I was taking nudes for my boyfriend, and I accidentally sent them to my stepbrother. I thought Marcus was going to be so mad that he had to see that, so I tried to explain. I was shaking! I guess I didn't have to apologize at all because he wasn't angry or disgusted. He was... turned on. His cock was so hard. Imagine how shocked I was when he let me touch it and put it in my mouth! It tasted even better than my boyfriend's, and it was bigger and thicker too. Fuck, I've never been as turned on as when he rubbed his fat dick against mine. I'm so happy I sent him my nudes. I'll do it on purpose next time.
