Moonlight Swim (with a Mom & Son)

It was a full moon. My wife and I went out for a swim, we never wear swimsuits at night, even though we are older. Our dear old friend and new roommate Louise came out to join us, she was already familiar with the dress code.  She walked out to the patio already naked, no towel, her full tight breasts bouncing slightly as she walked.  Single mother of 4 grown kids, she was staying with us until she could save some money, and get back on her feet financially, after a terrible marriage.  She gently walked down into the pool, and joined us where the shallow end meets the deep end.

 

We all got to gabbing, but whispering so as not to wake anyone.  I loved watching my wife and Louise interact in the pool, naked, their tits bobbing just at the surface of the water.  

 

I reached out and hugged my wife, and give her a deep kiss, as we floated, weightlessly. Every once in a while Louise would get close enough to me that I would grab her as well, with my other arm, and draw her in for a hug. My wife was ok with a little foreplay, but we had never taken it any further; well, not with Louise anyway.

 

Just as I was making real progress, and Louise was letting her hand accidentally brush, and then grab, my stiff cock under the water, we were all startled by a booming voice:

 

“Oh nice, and no one invited me?” 

 

It was Louise’s son, Robert [18], dressed in normal swim trunks and holding a towel. With the bright moonlight reflecting off the water, he obviously didn’t realize we were all naked. Before we could say anything, he ran and jumped into the deep end.  

 

My wife had decided at that moment to float on top of the water, exposing her huge breasts and hard nipples to the crisp moonlight air.  Robert came up maybe 2 feet from her fully exposed huge breasts. He was obviously shocked, and his jaw dropped, as he coughed up some water. 

 

Louise giggled nervously, at her son’s awkward reaction.  I said to her son, “you’re a tad over dressed for this party, young man”.   

 

“Oh, I can see that now!” exclaimed Robert, “I’m so sorry! I should go…”.  

 

Louise felt bad now. “No, it’s ok honey. We’re just skinny dipping, everyone does it. You’re an adult now, adults do this all the time.”  

 

“You do?” One surprise after another; poor young Robert.

 

“He can stay, but only if he follows the rules!” My wife was not going to miss this opportunity to see that huge cock Louise was always bragging about.  We assumed that Louise had seen it in many years, but she was always talking about how her son got his huge cock from his maternal grandfather. 

 

I started to feel a little inadequate for this party, but my average sized hard on persisted, as Louise had continued to hold me, and periodically squeeze it, as this conversation continued. 

 

“There aren’t really any rules”, I countered. “But it’s a pretty nice feeling, swimming naked, if you’ve never done it before.”  

 

If I can distract my wife with this big well hung kid, maybe that gives me more quality copulating pool time with his mother, Louise? 

 

Robert was still staring at my wife’s tits, as she floated in the moonlight. She looked right at him: “No touching, unless you’re naked too!” - my wife suddenly had a lot of convenient rules.

 

But it did the trick, young Robert slipped off his trunks, put them on the pool deck, and went right for my wife! He didn’t just grab her tits, he started sucking them, right in front of me, and his mother! 

 

“Robert!” Louise corrected him! “You need to ask nicely before doing that!” 

 

“Sorry mom!” He quickly looked at my wife “Mrs ____ , can I please suck on your tits?” - This was out of character for him, but he was half joking to lighten the tension he was feeling.

 

“I told him he could touch, as long as he got rid of those trunks” replied my wife, smiling, keeping the conversation as in appropriate as she possibly could.  “Robert, young man, you can have me. Do anything you feel like doing to me. My husband has been ignoring me, he would rather get a hand job from your mommy, it seems.” 

 

My wife and I had fantasized about Robert fucking her for some time.  She already knew she had a green light for fucking him from me, if she could manage it. She liked younger men. 

 

I swam behind Louise and cupped her tits in my hand. She tightened her grip on my cock, as we both took in this “age-gap” porn show. 

 

I couldn’t be sure, but as she lowered herself into the water, my wife must have found his huge young cock with her hands under the water. This, because they both looked surprised and pleased with themselves, at the exact same moment.

 

I took the opportunity to lower my right hand to Louise’s right thigh, and then run it over her pussy.  As she parted her legs for me, she whispered “he’s never even had a girlfriend. I thought I was going to have to take him out to a strip club.” 

 

That image danced around in my dirty mind, for more than a few moments.  “If you ever do that, Louise, I’m coming with you! I’ll even drive, and spring for your drinks!”

 

My lovely bride’s arms were now around Robert’s neck, and her legs had wrapped around his mid-section. They were totally fucking. Definitely, this kid was fucking my wife, as she floated in the water.  My 49 year old wife was fucking an 18 year old boy, right in front of me … and in front of his mother! This was so hot! 

 

“Shall we join them?” I asked my dear old platonic friend, Louise. She spun around and lifted herself onto my cock, allowing me to penetrate her underwater.  Oh, god, she felt so fine, wrapped around my cock. We had a long history of platonic friendship together, with only occasional flirting.  I love consummating old platonic friendships with kind, consensual and loving sex. She hugged me tightly, and started kissing my neck.  I loved her; I always have. And now I was inside her, after all this time.  All was well with the world, I jammed my stiff penis in and out of her motherly pussy lips, as we both appreciated the view of my wife, doing her son.

 

We swam as one, edging closer, ever closer, to her son Robert, and my wife. 

 

Robert and I now had our sex partners up against the wall of the pool, side by side, and I positioned Louise as close to my wife as possible. 

 

My wife gave me a devilish look, grabbed Louise’ hand, and pulled it underwater. 

 

“Feel your big boy, Louise.  Feel your big boy going in and out of me.” She had Louise place her hand down between her legs.  Louise could feel her son’s thick stiff cock as he slid his shaft in and out of my horny wife.  

 

I was staring into Louise’ eyes, as she felt her boys cock and my wife’s pussy.  I was still slamming my cock into her.  

 

She returned the eye contact, as I plunged my cock in and out of her pussy. “How does he feel to you? Do you like feeling your boy’s cock while he fucks her?” I asked. Her eyes became dreamy, glassy … “He’s my good boy, mommas good boy.”  She turned her gaze to her big baby boy.

 

I motioned to my wife, it was time we got these two together. We had fantasized about doing this for a while now. My wife reached her hand down and removed Roberts huge member from between her legs, but held onto it as she slid out of the way.  I pushed Louise through the water to take my wife’s place in front of her son, grabbing one of her legs to make sure she remained open, receptive, for her boy’s dick.

 

My wife guided Robert’s cock towards his mother’s sex, and lined it up to her pussy. “How many of your young friends can say they have fucked their mothers, Robert?” Asked my wife. 

 

“Mom?” Asked Robert, pleading with his mother … he really wanted her, but he wanted her permission first …

 

“Do it, Robbie” Louise whispered … “Do it to me … now!” 

 

I was spellbound. 

 

Robert pushed forward slightly, allowed my wife to rub his mothers pussy with his cock, sliding it up and down her slit. Louise reached down and adding her hand to my wife’s, they felt her boys penis slide between their fingers, into her beautiful momma’s opening. 

 

My wife told me later how blessed she felt, feeling his cock returning to her vagina, re-entering that soft home for his body. Such a blessed event. 

 

I could only watch her motherly gaze into his eyes, followed by her eyes closing at the magnificent pleasure of receiving her young son, back inside of her once again. 

 

“He’s a qualified mother fucker now!” was all I could say, which thankfully got at least a slight smile from Louise.  Robert wasn’t even listening, he was somewhere else. We could see the underwater thrusts into his mom’s cunt picking up the pace, as Louise began clutching at his hair, wrapping her legs around his torso, allowing his dick to penetrate her over, and over, and over. 

 

Robert walked her to the shallow end as he fucked his mother furiously, and my wife and I followed them, transfixed at the sight of this mother son sex show, in our own backyard pool.  

 

“Oh mom…” 

 

“Oh, my beautiful baby boy” 

 

Suddenly, Robert shuddered violently and pulled out of his mother, just in time for us to view his violent ejaculation into the pool water, the three of us watching his semen dart and spew from his huge cock, towards his mother but rendered harmless outside of her womb … Louise grabbed his hard cock and squeezed ever last bit from it, then dipped her face into the water and emerged with his cum dripping all over her face, sticking to her hair. She grabbed her son and kissed him, his family cum sliding all over their lips as they embraced, and sucked each other’s tongues like small penises.  

 

Thankfully, Robert "allowed me" to continue fucking his mom, even though they started sharing the same bed, from that time forward. In return, I allowed him to do whatever he wanted with my wife; and I know the three of them enjoyed each other as a threesome on more than one occasion.  

 

Meanwhile, time passed.  Did I mention, she was a single mother of 4 adult children? She has two daughters, and another son.
