I arrived in Colorado last week and it has been great. The weather has been awesome and I’ve reacquainted myself with Kip’s hottub (and his cock)....Last night (Friday) I thought I’d have the house to myself as Kip was going to spend the weekend down in Denver. On Friday morning Kip asked me if it was OK, if some friends of his crashed here, of course it was OK with me, it is his house and I’m a guest. Kip said the couple, Jeff and Stephanie, are long time friends and were coming up after work to. "What would you do if I told our younger sister about us, I mean I am not going to lie, she is very young, and she is kinda sexy don't you think?"

I do not know, what she meant when she went back in the room but before that she told me that she would not hurt me and I should not hesitate and come quick. Seeing her go in, I moved to stand up, adjusted my erection in the jeans and walked over to her to kneel on the.
