I was thinking about my friend Shawn’s sister Carol ever since she let me fuck her a week ago. She really is a hottie. I should take advantage of the fact she seems to be a nympho. The only thing missing from our adventure was getting their dog Rocky to fuck her while I watch. I’m going to have to go over there this weekend and hope that she is around and feeling horny.

I talked to Shawn during school and told him I was thinking of coming over this weekend if it was ok. I thought maybe I could spend the night. He said no problem so I was anxious for the weekend to roll around. I see Carol in school all the time and she is always smiling at me which is a good sign that maybe she would like for us to repeat our tryst. She is always walking with some cute friends too. I wouldn’t mind her having them over for a nice fuck session but it would be ok if I was only with Carol.

The weekend arrived and to my dismay Carol was going to spend the night with one of her girlfriends. Shawn never told her I was going to stay over. I saw her on her way out and she gave me a wink. She was in a mini skirt as usual and damn she looked good enough to eat. Their dog Rocky came over to me wagging his tail. I guess he remembers his treat from last time so I was thinking maybe at least I could have Rocky fuck me. Shawn and I were watching TV and it was getting late. Rocky was lying in a corner and Shawn said he was tired and was going to bed. That I could stay up as long as I wanted. His parents are cool people and trust us with everything. They had gone to bed a long time ago. When Shawn went up, Rocky came over and laid next to me. I started to get a hard-on thinking about the possibility of letting him fuck me. I was just so afraid someone would come downstairs and catch us in the act. I wouldn’t be able to take the embarrassment. I was petting Rocky and he flipped over on his back and had the tip of his dick sticking out. He was panting excitedly. I looked upstairs and didn’t see any lights on except the bathroom light they leave on when someone is still downstairs.

I didn’t hear any sounds so I decided I would get a little risque. I dropped my pajama bottoms and my underwear as I started rubbing Rocky’s belly.
