I'm 47 years old and find myself in a sexless but otherwise happy marriage with two great kids. We live in a great neighborhood with lots of kids playing in the street and we, the parents get together and have some beers in each other's yards while they play. All the parents are roughly the same age and we hang out a lot.

This particular story came from out of nowhere. One afternoon me and one of my neighbors got on our bikes with the kids and went to the playground. It's a big park with a playground, splash pad, and lots of trails to play on. The kids are old enough to venture out on their own so Liz and I set up in a tucked away picnic shelter. We had snacks and lunch for the kids and some adult beverages for us to pass the hot summer day while they played.

Liz is a stay at home mom, 39 years old. She is about 5'4" with a modest chest size (B-cup at best) and fairly full size but. You would say she is athletically built but a little more junk in the trunk these days. She has a pretty face with brown hair. She is attractive but I never really paid her a second thought.

The afternoon went on and Liz and I chatted in the shade and drank some beers as the kids wandered off and did their thing. Pretty standard conversation. No flirting. No sexual tension. Then by a miracle, Liz opened herself another beer but it exploded all over when she popped open the bottle cap. It must have gotten shaken up on the bike ride. It exploded all over her shirt and all over the lap and crotch of her yoga pants. We chuckled a bit about the explosion and I grabbed on the kids towels to help dry her up. She giggled and joked that the beer on her crotch was going to probably give her a yeast infection. I joked that she was wasting beer and I offered to slurp the beer out of her pants. It wasn't a sexual joke. Just a joke about wasting beer. But then, without even hesitating she stood up, pulled her yoga pants down to her knees and leaned over the picnic table and instructed me to clean her off. No warning. No flirting. But there I was with this amazing ass facing me, bent over a table. I didn't think. I didn't hesitate. I got up, got down on my knees and buried my face in her pussy and ass. We were lucky as we were in a pretty secluded spot and we could see anybody coming before they could really figure out what they could tell what we were doing.

I started licking her perfectly shaved pussy and pulling her ass cheeks apart. Her ass and pussy were damp with the cold beer that just landed on her. It was the most sensual smell of pussy juice and beer. She moaned in absolute pleasure. She moved her legs further apart to give me as much access to her pussy as I could get from that position. Her hips pushed and bucked back into my face. She was going nuts. I occasionally flicked my tongue on her ass and that sent her into orbit. It wasn't long before she reached a huge orgasim.

I stood up from my kneeling position and looked at her still face down on the table breathing heavy, legs trembling from cumming so hard. After a few seconds, she got up turned to me and dropped to her knees. She pulled my shorts down and pulled out my throbbing hard cock. She was crazed...stroking and sucking my cock. It was all I could do to keep from exploding in her mouth.

I then pulled her on her feet and laid her back on the table. I looked around to see if the coast was clear and then I took off the soaked pants that were still at her ankles. I put her legs on my shoulders and positioned her so her ass was off the table. I took my dripping cock and easily slid it into her hot, wet pussy. It was so tight and wet. It was incredible. I slowly pushed it in until she had every inch of me. She lifted her top and played with her nipples as I picked up the pace and started fucking her faster and faster. She took her legs off my shoulders and pulled them back almost to her head. I was so deep in her now. She was going nuts. My balls were slapping against her ass...her pussy was so wet it was dripping down her ass. I kept pounding. I knew there was no way I could hold my load much longer. I emptied my balls into her pussy as she climaxed again. I leaned over and gave her one long kiss then we both quickly and quietly put on our clothes and composed ourselves.

We didn't say much after that. She thanked me and said she had not had sex in over a year. I told her that it was probably longer for me. That was it. No further conversation about it. We just went back to drinking and small talk the rest of the afternoon. Will it ever happen again? I don't know. But you can be sure I'll shake up every beer can from now on just in case...
