Forbidden Summer Love

I have been married for a little over 6 years. I do love my wife but she has no idea what I really think of her middle sister. A little background, my wife is the oldest of three sisters, her middle sister, Sara(not her real name) is the reasoning behind this story. My wife, Tammy, is very sexy. She has great boobs, curves and knows how to please a man. Sara, on the other hand, has huge boobs, a great ass, and a great set of DSL's. That's dick sucking lips for those that don't know. Anyway to the point.

When I first met Sara I didn't think about her, I mean she was pregnant with her 3rd or 4th child, I really can't recall which one. She has a very sexy body for 5 kids, by the way. So when I first met her I thought nothing about her. Then one day during a very hot summer she invited our family over far a swim in the pool. Everyone was having a great time playing in the water and splashing around. Sara came outside with a white T-shirt and shorts(no bra). I really didn't realize she didn't have a bra on until she got out of the pool and walked right by me with those huge tits flopping around trying to find room to breath in that tight ass little white t-shirt. She has those huge pepperoni style areola around her huge eraser size nipples and I immediately found myself needing to get back in the pool. After a while of watching her run around, tits bouncing and seeing her bend over in those booty short, I couldn't take it anymore. So I told my wife, "Gotta hit the restroom". "Ok", she yelled back. I made it the restroom without anyone noticing my throbbing hard on through my shorts. Once I was in there, I pulled my shorts down and my cock was already slippery with precum, so no need for any lube. I went to town on my throbbing cock. Squeezing and releasing pretending it was Sara controlling her pussy muscles. After just a few short minutes I came all over a towel, cleaned myself up and headed back to the pool.

I've used many thoughts about my sister in law over the past few years and all of them have been very hot and erotic. One day I got a call from my wife. "Sara and her family need a place to stay for a few days." I was so excited. I just new I'd get to see her in her night clothes and just imagine how few clothes she had on underneath. Once they got all moved in and settled we(the adults) decided to have a few drinks and play some cards. That went well and we all had fun, even though I couldn't keep my eyes off my sister in law's gorgeous set of tits. When we called it a night I spent some time alone in the restroom while my wife slept off her drunkeness. After I got myself off I then went to bed and fell asleep.

The next morning, I was off, my wife was at work and I was home by myself. I had no idea where my sister in law and her husband were. I took the time I had alone to stroke myself off once more to her tits. I laid in my bed with some lube and closed my eyes. I started slow, rubbing my cock until I felt it start to throb. I then grabbed it gently with one hand and began to stroke slowly, as I rubbed my freshly shaven balls, I began to stroke faster. I felt myself let out a deep breath as I stroked harder and faster. I, unexplainably, opened one of my eyes just enough to see Sara standing there. "Thinking of my tits", she asked. I muttered and stammered while trying to cover up. She started to walk closer and my mind began to race. I couldn't believe what was about to happen. "I asked you a question", she demanded.

"Yeah, Sara, actually I am".

"You like my big, gorgeous, voluptuous, needy tits?"

"Yeah", somehow this was the only word I could think of.

"You want to suck on my nipples, play with my tits?"

"Yeah".

She stepped closer to the bed and placed a hand on my thigh. I could have came right then but I held back. She slowly moved up towards my balls. "Mmmmmm, Jerry doesn't shave, he's all hairy and smelly. I can never suck his dick long enough to really get in the mood. Can I suck yours?"

"Yeah, sure", I managed more than one word out this time.

She looked directly at me as she slowly moved her head towards my throbbing, slippery, rock hard cock. She stuck her tongue out and licked from my balls to the head of my cock. She stood up, looked down at me and got naked. She had on this little white sundress that you could damn near see through and nothing else. To see my sister in law standing there totally naked and about to do things to me I've only imagined, almost cause me to blow my load. She focused her attention back to my cock and this time went she went straight for the head. In on motion she had my entire 8 inch cock in her mouth. She stopped at the base, made a small gagging noise and licked my balls. I could've exploded in her mouth but held back. As she slowly sucked my cock, she would give me a little look every few minutes and I would give her a smile to let her know I enjoyed what she was doing. I ran my fingers through her long wavy dark, almost black, hair. I sat up grabbed her upper thigh and pulled her on top me. She had little brown pubes in a cute landing strip shape, her pussy lips were as smooth as her ass. I grabbed her ass and pulled her pussy closer to my mouth and the sweet smell of her pussy had taken over the room. I gave her clit a small lick and she let out a moan. It was a moan I was certain she hadn't let out in a long time. I could feel her juices begin to flow out of her pussy and into my mouth. She began to move around and wiggle her hips and let out a loud moan and she came all over my mouth. She turned herself to where we were face to face. "I want to taste my pussy", she said as she began to kiss me. She grabbed my cock and slid it into her pussy. I couldn't believe how tight she was. She had a little trouble getting it inside her. She wiggled around and sat up until my entire cock was inside her tight slippery pussy. She grabbed my hands and placed them on her tits. I squeezed her nipples as she rode and bounced on my cock. I felt her quiver as she came. This time I felt juices go down my cock onto my balls and down the crack of my ass. I took her in my arms and flipped her underneath me. This time I was on top. I took her ankles and brought them to her head and looked her body and "wow" was all I could think. She had a great body and I couldn't believe I was having sex with this woman. I had been fantasizing about her for so many years and now I was fucking her. "Fuck me harder!!!", she screamed. She played with her clit and kept yelling for me to fuck her harder, faster, and deeper. As I got ready to come she sat up took my cock in her mouth and slid it all the way to the back of her throat and swallowed every drop of my come. I was so horny, still. I stayed rock hard. She got up and said, "this never happened and won't again." "Ok", I replied.

That night we were in the kitchen, my wife in the shower, her husband working on his car, and she went to the oven opened and bent over to check the chicken. When I looked, she had no panties on. She looked back at me and gave me a "come get it" smile. And winked at me.
