You know Joey, nobody is due to be home for at least another hour and your dick gets me really turned on, why don't you and I just get in bed and fuck some more like the other day? Well what would you say? I was ready before she finished her question as my twelve year old penis grew hard as a rock immediately and stood proudly in full salute to the best sister a guy could ever want. I admit that it was weird that my nephew was on her other breast doing the same thing but he was completely unaware of my presence and my delightful sister reassured me by stroking my head with her fingers running through my still somewhat innocent locks of light brown hair.
