As I cum inside her Caitlin moan 'ohhh baby I can feel your cock pulsating and cum inside me... I hope you have more to offer me tonight baby'. As I r...ecovering and still laying on top of her with my cock still semi hard and deep inside her, Caitlin turned and said 'mmmmmm you are still hard and I can feel it' and with a seductive look in her eyes she started to move her hip up and down. After a few minutes of this and to my surprise I was rock hard again, she asked me to swing her up to the. I know it was six inches because he measured it one time. He seemed to slow a minute and then I could feel his cock actually begin sliding forth and back now inside of me, rubbing everywhere in there and at the entrance.

It must be from riding in the car all day!” She giggled and I knew she was just giving me a hard time, as c*usins do to each other. I said, “I can tell we’re going to get along really.
