I had been hanging out with my friend Nicole for the day, tanning by her parent's pool. She was very hot, but my league, but she liked hanging out wit... me as a friend. She was telling me how she was having an affair with a local married businessman. Nicole is only 20, but this guy is almost 40 with 2 k**s. She told me she realizes it isn't going to last and doesn't want to break up a marriage or anything, but confessed that she loved that he was this big strong, hung man that was so into. Suck my tits! Your cock is hard again! You must love sucking on your big sis’s tits!" I didn't say a word, I just ran my tongue from one nipple, down her big tit, up the other one to her other erect nipple; giving that one happy, long suck. The minutes passed by like hours as I lavished her glorious melons with incestuous lust. I licked and sucked my way to all new heights of lustful pleasure. Lora moaned away and kept grinding her crotch on my erect, throbbing shaft; I kept thinking that she. I heard a bark out back and it sounded like a large dog, "And when no one wants to fuck bring the dog in too." and everyone laughed. "How do you want it" one man said with a nice sized cock getting between my legs. "As hard and deep and as much as you have and as many at one time as you can give me and I want all the cum in me and on me so get to it." I said and the cock sank into me and he began fucking me. It felt so good, I sprayed his cock with my first orgasm of the weekend and he had just. I looked into her eyes as this was a position she would find hard to escape from and as I felt my hard cock press against her pussy I saw the look of desperation on her face, she tried to wriggle free which probably wasn’t the best idea as the more she wriggled the more I thrust forward to hold her down.The let out a soft cry as I felt the warmness and wetness of her pussy as during the frenzied struggle my cock had somehow found its way inside her again, I had her this time and began pushing.
