Then Markus removed his bath suit and naked he straddled my back once more. I could feel his aroused huge cock lay heavy on my bare buttocks. I let h...m spread my ass and lay his cock lengthwise between my cheeks. This caused his cock to grow fully hard. He was very well endowed. He started to move his cock back and forth.
