I put chairs set up around the bed. After a hot shower and touch up shave of her pussy and asshole she told me that she also douched her butt so she could take a long thick cock in her shitter. She put on a thong bikini bottom and remained topless, she said she was to receive her guest. She slipped on a pair. "Anything" i said quickly. "Come to my room in a minute" and she left te room. fixing my trousers i waited and then headed through to laurens room, i walked straight in and got the biggest surprise of my life.My sister was standing in the middle of her room totally naked, my jaw dropped at the sight. Wow, was all I could say. "I take it I'm not ugly then??" she asked smiling as she pointed to my hardon straining through my joggers. I naively tried to hide it and blushed. She sat down on the bed. This time, instead of jerking me off, she knelt down with her mouth an inch from my hard cock, looked up at me and said, “OK?” Of course I nodded.That was the best fellatio I have ever had. I was still standing and had to sit down immediately after she accomplished her goal. I watched her swallow, smile and ask, “OK?” I couldn’t speak, only nod. I slept!After a couple of $10 tip sessions she surprised me yet again. Instead of kneeling she slipped out of her pants and pointed to the darkly. He then grabbed my head again, pushing it even deeper. I felt like I was going to suffocate, couldn't even cough with his dick deep down in my throath. Since I couldn't swallow my saliva was dripping on his balls. His cum was sweet, better then of the rest. - Yeah bitch. That's it eat that big black dick. You're getting better at sucking, alright.
