“Well big brother, I’m horny, and you’re obviously horny too, I can imagine you are someone else, but I need that dick inside me.”Without sayi...ng anything she unclasped her bra, revealing her soft, young breasts. She did look amazing and I started salivating.She walked calmly over to me and pulled at the towel I was wearing, making my cock bounce forward. She gasped as she watched it bounce, grabbing it to steady it.

I could hear him pulling off his shirt and unzipping his pants; I wished I could see how hard he was and how much he wanted me.
