My wife Carol and I were down at our local nude beach, with her sister Liz, and Liz's husband Luke.
This had become a regular thing for the four of us. All through summer we would head down here on Saturday afternoon. Then afterwards head into town for dinner and a movie.
I don't even remember how we got started with this routine. I think if I remember correctly I suggested the beach to Carol and she was too shy to try it on our own, so she invited her sister.
I didn't mind the extra company, Liz is as hot as any sister in law could get.
Liz and Carol look very much alike, there is no doubting that they are sisters. At twenty three, Liz is the younger one, Carol is twenty six. Both are five foot six inches, slim, and both are endowed with D cup titties. They are both brunette with hazel eyes, although Carol always dyes her hair so it is sometimes hard to remember what her original shade was. Carol only waxes the edges of her pubic area for her bikini, but she keeps the rest neatly trimmed. I was stunned the first time we came down here. Liz keeps her pubic area totally bare. Unlike Carol, Liz also has very prominent, protruding, inner labia lips. The kind that are perfectly made for sucking on. I keep thinking to myself "Damn Luke, you are a lucky bastard."
Luke and I are also pretty similar to look at. I'm five foot ten, and Luke about five foot eleven. I weigh one hundred and eighty five, and I think Luke would probably go ten to twenty pounds heavier than me. In contrast to our wives, I keep my pubic area completely bare, while Luke leaves his natural. As far as cocks go, I've seen Luke with a hard on more than a few times, and he is about seven inches long, and almost two and a half inches wide. I'm almost eight inches long but not quite as thick as him.
We had been on the beach for about two hours when I felt the need to head to the toilets. We had a cooler full of beers with us and beer always seems to go straight through me.
I stood up and said, "I need to leak, back soon."
I headed up the beach to the toilet block which is located near the path that leads down from the car park to the beach. Once in the building, I headed straight to the urinal and let rip with a long steady stream. I had just finished and was squeezing out the last few drops when a hand and forearm was wrapped around my chest, and a second arm was pressed across the back of my neck, pressing my forehead against the cistern. The voice in my ear hissed, "You came in here to get yourself fucked, didn't you?"
"You want a man to shove his big cock into you and fill you with his cum, Don't you?"
Without waiting for a response he lined his cock up with my anus. I felt the head of it pushing against me. I clenched my anus shut tight to make it hard for him to penetrate me.
He had obviously lubed himself up before he came into the toilets because I couldn't stop him entering me. In one slow and steady push he drove his entire cock deep into my body. He didn't stop until his balls were pressed against mine, and his hips were pressed hard against my butt cheeks. "You like that, don't you?" he hissed, "Feels good to have a big, hard cock deep inside you, doesn't it?"
I couldn't say anything as the hand that had been pushing my head against the cistern had moved around to cover my mouth before he penetrated me. All I could do was moan into his hand.
He started to withdraw his cock until only the head was left inside me, then he again slid the entire length of his cock all the way into me. "Yes, you love it." he hissed, "I can tell from the way your sphincter keeps clenching around my cock each time I try to withdraw."
Again and again he would withdraw until only the head was inside me, then he would thrust himself forward until he was fully inside me again. With every stroke he was driving his cock over my prostate. I could do nothing to stop my cock from getting rock hard. I could do nothing to stop my cock from twitching and jerking every time his cock pressed against my P spot.
"I'm going to cum soon. Going to fill your bowels with a load of my cum." he hissed in my ear "You want my cum inside you, don't you?" he whispered "I want you to cum with me. Will you do that for me?"
I could only moan, as he started to increase the speed of his strokes. Every stroke was all the way in and all the way out, and every stroke pushed hard against my prostate. It was as if I was having a long, non-stop orgasm.
I couldn't help myself, I squealed into his hand as I started to ejaculate into the urinal in front of me. At the same time, I heard his guttural grunts as he pumped shot after shot of his cum deep inside me. He held me against him as his thrusts became less intense, as the last of his cum left his body, leaving him totally drained. Once his cock started to soften he eased it from my ravaged anus, as he removed his hand from across my mouth, he whispered, "God Damn, man, You are an amazing fuck, did you know that?"
I turned on him and hissed "For fucks sake Luke. What if somebody had come in here?"
He grinned at me, "I would have invited them to fuck you as well." he said.
He even sounded like he meant it. Although I don't believe for one second that he would be willing to share me with anybody else.
Luke and I had been fucking for about the last six months, but only when the girls were not around.
It all started on a weekend fishing trip. We had both been drinking, and when the time came for us to hit the sack we discovered that one of the sleeping bags had gotten covered in fuel from a leaking jerry can. We shared one sleeping bag that night, and with us both being a little drunk, and we were both horny, without our wives there to look after us. It works for us. We found out pretty much straight away that I can reach orgasm as a bottom, and Luke was happy as a top. We did try it once the other way, but neither of us found it satisfying, so we actually quit before either of us reached orgasm.
"Come on, we better get back before they come looking for us." Luke said.
As we walked back down the beach I could feel Luke's cum starting to trickle from my anus and dribble down the inside of my thigh. "I need to go for a swim before we rejoin the girls, I'm leaving a snail trail."
Luke laughed. He headed towards the girls while I headed towards the water.
When I got back to where Luke and the girls were sitting, Carol said to me, "What kept you? Luke said that you were gone so long because you both decided to stop for a fuck!!"
"Yeah, Luke thinks he's a funny bastard. I wouldn't fuck him if he was the last pussy left on earth."
We all laughed, Luke and I exchanged a wink.

After spending the afternoon at our local nudist beach we all went out to dinner. We found a really cozy little seafood restaurant not far from the beach, and selected an outdoor table that overlooked the ocean.
While we enjoyed a bottle of wine and a couple of excellent seafood baskets, we discussed plans to go see a movie after dinner. We came to the conclusion that there was not a single movie on that was worth watching.
"OK," I said, "Anybody got a good idea on what to do after we finish here?"
Liz said, "It's a beautiful night, we could just go back down to the beach."
"You're just hanging out to see me naked again." I said, laughing.
Liz grinned at me, "Apart from Luke, you are the sexiest man I know, and I love seeing you naked."
"LIZ." Carol said, rather abruptly "That is my husband you are drooling over!"
"It's OK Carol. You can drool over me to make it even." Luke said, spreading his arms wide towards my wife in a welcoming gesture.
Carol smiled at him, "Mmmmhh yummy, what are we waiting for, lets head for the beach."
I couldn't help laughing. I couldn't help wonder where this little party was going.
After all, we had never all flirted like this before. In fact I would not have believed that either Carol or Liz were capable of flirting. Carol and Liz linked arms and started skipping towards the beach.
Luke and I walked behind. I think we were both checking out both our wives butts at the same time.
Once back on the sand we all wasted no time getting our clothes back off. There were still quite a few people at this end of the beach as it was close to the car park, and also the restaurant and cafe strip. Luke suggested that we go for a walk along the beach to get us away from the crowd a bit.
We had walked several hundred yards along the beach when we decided to stop and rest.
We dropped our cooler, towels, and tote bags on the sand. I opened the cooler and pulled out a beer "Luke?"
"Hell Yeah." he grinned.
Carol said to Liz, "coming for a swim?"
