Then she stopped. She said. “ come here” I moved around to the front of her and she asked me to kiss her which I did. She held me by the back of t...e neck and looked into my eyes. She said “My god his cock is rock hard against my clit, I want him in me” i didn't know what to do or say, I was so turned on, I just thought, fuck it, how often does any woman get to ride a cock like that.I looked at her and said ”So do I” and got off the bed. She said “ I want you to fuck me Ken! will you?” He looked. I laid my shirt out next to the pants, and turned to face my companion.I was in my shorts and “wife beater” undershirt, and was surprised, to say the least, to find that Emily was nude. She embraced me, and hummed her approval of the warmth I contributed to the clutch. I reached, tucking in the blanket behind her, and settling the sleeping bag more closely about her. She wriggled in approval. I settled my hands on her back, thinking that would be taking less liberties with her nakedness, than,. I took the daypack as a pillow. Legs widely spread apart to give them an unhindered look on my testicles; I began to fondle my balls tenderly.Every now and then I batted my eyelids to look over to hem. Slowly I hardened. That took a while. Two or three walked by, stopped or knelt down to wank and spray into the sand.I was about to cum when she got up and walked over to me. She knelt in front of me. Her grip was surprisingly firm but not unpleasant. I straightened up and grabbed a tit. I also. I was a little weirded out, but decided that, since it was an old house, maybe a draft had pushed it. As I plopped down the stairs, I could already hear my sister whining."But mom. I didn't want to move anyway. I am 18. You could have left me with Aunt Sue and Uncle Brett to finish out my senior year. Why didn't you?" Now, Sara," I heard my mom say. "You know that I don't like your aunt's husband. He is a perv and looks at you like you are a piece of meat. Besides, can you at least give this.
