That is what I hoped you would want to do tonight.” I said before I kissed her. “I opened it up this afternoon and made sure I put on clean linen....” We kissed again and she said, “I am so excited! I can’t imagine a more wonderful way to enjoy nature and the spring and summer months falling asleep here.” I kissed her long and passionately as she practically climbed up my frame. I wanted actually wanted to tease her a little and build up to this evening teasing and building her desire into an all. Thinking about that tongue and what it could do to a helpless cock had mine twitching. Hearing a sweet, subtle moan from her bedroom I gritted my teeth. Squeezing the base of my cock, I pictured my sister above me, her full breasts hovering over my mouth, her cunt gripping me in a vice. Moving my hand up and down my rigid penis I could hear more sounds from her bedroom, my back arched into the hollow touch as I continued to think about her sweet young body. I hadn’t always. With heart pounding I said “why don’t we go for a swim”. “It’ll be pretty cold” said my Dad “But yeah, why not”. I took my shirt off and Dad did too, revealing his muscular hairy chest. It was a great sight and I instantly go flashes of his best mate Uncle Mark running his hands over his chest as he sucked my Dad’s cock. “Think of something else”, I thought as I felt a twinge in my pants. Dad had his pants off and was walking down to the water in his underwear, I could see his manhood. !” I told her and immediately began to strip her clothes off. At that time we,d never had a threesome before, but all that would change shortly once she was in her natural bare skin, those lovely big titties on show, dark pubic hair in contrast to her platinum blonde beehive hairdo, fleshy labial lips puffed up and leaking juice. I dived down to kiss her sensitive clitoris then began licking her pleasure slit as she closed her eyes to enjoy the feeling. Meanwhile Burt had stripped off to reveal.
