My wife of 23 years is an uncannily sexy woman. She’s 5 feet tall and weighs around 110lbs, and has a 32C-21-36 body with a “JLo” ass. Her creamy skin, auburn hair and big almond shaped green eyes make me feel like a fortunate man after all these years.

Eleven years ago we visited her older sister and brother-in-law for the Thanksgiving holiday which is our normal custom. The sisters have a close relationship and we visit four or five times a year between our home and theirs. They have a son, who was fifteen and a virgin at the time. From the time my nephew was six years old he had a fascination with my wife; they wrestled and played rough constantly to the point that it became so commonplace that everyone in the family would smile, shake their heads or just roll their eyes with a “there they go again” attitude.
As our nephew entered his teens my wife mentioned to me in a joking way on several occasions that the play seemed to be taking a more sexual turn. She thought he was taking the opportunity to explore her body through her clothes and at times grinding his dick into my wife’s ass. I told her that if she thought this was the case she should stop it. My wife would just chuckle and say that it was nothing – he was just a kid.
On one occasion he waited until his dad was working the night shift and my wife was in a short nightshirt and panties to launch an “attack” He was fifteen and playing baseball, therefore strong and rather fit. My nephew caught his aunt leaving his mother’s bathroom while my sister-in-law and I were in the kitchen talking. Clad only in his boxers he caught my wife around the waist and tossed her on his parents` king-sized bed. He immediately crawled on top of her pressing his hard erection squarely on my wife’s bikini covered pussy while holding her down and playfully biting her neck and shoulders, my wife tried to throw him off. She kept hissing at him to get off of her, but he kept on, now moving his hips against her crotch. His erection, now hard and big, was pushing against her pussy.
He was really getting into it, dry-fucking his aunt was driving him crazy. The heated friction on my wife’s clit was sending sensations through her body and making her pussy very wet.
Once again she told him to stop, but this time in a low, firm voice. He was too big, way too strong for her to force him off her.
“No!” He said in a choking voice, “Please no, I can’t” He was now thrusting between his aunt’s shapely legs; she could feel his dick swell against her now sopping cunt. Burying his face in my wife’s neck he ground his hips into her crotch. His aunt’s grapefruit sized tits were mashed against his chest as his cock exploded, soaking the two of them with torrent after torrent of teenage cum. He pushed his upper body up as he ground his hips in a circular motion mashing his spasming cock on my wife’s pubic bone, squeezing out every bit of jism.
When he finished, he got off my wife and without a word to her left the room and went into his own room, shutting the door behind him.
A few minutes had passed when I entered the guest bedroom and found my wife sitting naked on the side of the bed, holding her completely soaked panties.

“What’s going on?” I asked as I shut the door.
“Basically,” she said in a low voice as she looked up at me, “our nephew fucked the shit out of me.” As she said this she handed the funky panties to me.
“What the hell are you talking about?” I was shocked. I took the panties, feeling their soppiness and smelling the unmistakable aroma of male cum and my wife’s juices. Numb. I tossed them in our dirty clothes bag as my wife said in a voice barely above a whisper:
“I had an orgasm. My nephew was fucking me hard through our underwear and I orgasmed as I felt him cum. What is wrong with me?”
She was sitting beside the bedside table with the lamp on. It was the only light on in the bedroom causing a soft glow to fall over my wife’s partially open legs. Her inner thighs and nearly bare crotch glistened.
“Nothing baby, it wasn`t intentional. You never meant it to happen but it did. He isn’t going to say anything and I don’t think you should. You can get him alone tomorrow and talk to him.” I was trying my best to be sensible but the image before me and the knowledge of what happened affected me in a weirdly erotic way. My wife looked up at me through her thick shoulder length hair. Her eyes were wide and for the first time it dawned on me that she was so aroused she was beside herself. She took my hands and roughly pulled me down on top of her. We couldn’t get my clothes off fast enough. Once undressed my wife climbed on top of me and in a voice that I barely recognized said:
“I want to fuck you.”
She did.

My nephew said little when my wife pulled him into the guest bedroom the next morning and told him she truly loved him but what happened the previous night could not happen again. She assured him she would never say anything to his parents. He thanked her and left the room.

It didn’t happen again. For nearly two years the play between them was less frequent and much more platonic. His parents even remarked to us in a summer visit to our home that they thought their son was “growing out” of the rough play.

My wife and I have never had children, so on our nephew’s birthday we always drive to my sister-in-law’s house for his party. He was now seventeen and the party was attended by twenty or so high school kids and we adults worked our asses off to host a successful event. I noticed on several occasions my nephew looking at my wife hungrily when he thought no one was looking. I saw it and it was obvious to me he was undressing her with his eyes and fucking her with his mind. It was no wonder. My wife was barefoot wearing thin, low riding white shorts and a yellow tank that in the early August sun clung to her tits from her sweat. It was an outdoor party in my sister-in-law’s big landscaped backyard.
I caught my wife inside as she was getting a platter of sliced tomatoes.
“Hey hon, ______ is ‘jonesing’ for you.”
“What?” she said partly shocked and partly embarrassed, “Baby, that’s in the past don’t bring that shit up now.”
“So you noticed?” I asked.
“Yes, of course but that was then, nothing has happened since. It’s alright.”

With that, she went back outside.

It was very late when the last of my nephew’s friends left. My wife had showered and was in the guest bedroom preparing for bed. I was in the bathroom across the hall taking my shower while my nephew and his parents had gone to bed. Or so I thought.

I finished my shower and went about my nightly routine of drying off, brushing my teeth and pulling on a pair of boxer-briefs. I opened the door of the bathroom and stepped into the hall. I could hear the sound of hushed, emotional voices and of weight shifting and moving on the bed in our room. I stepped to the door and realized it was barely shut. I pushed it open a bit; I don’t know why I didn’t just shove it open and enter the bedroom.
My nephew was lying on top of my wife, his hips between her legs. Her beautiful legs were spread wide bur her hands were on his shoulders holding him at bay, He was naked and a towel lay on the floor beside the bed. My wife was topless, her round breasts completely exposed but she still had her little panties on.

“Please Aunt _____, let me do it to you just this once.” He was speaking in a low whisper, “Everything was cool when it happened last time, I want you so bad.”

“No _______, we can`t!” My wife answered, “This shit is evil. Last time it was a situation that got out of hand, this is different. If your parents found out it would tear them apart and this whole family”

“Who has to know? No one found out last time, please. I haven’t been with a girl since that happened and no one found out then and no one will find out now!”

“Your uncle is across the hall so get off of me goddamnit!” My wife hissed.

“He’s taking a shower and he’s always in there for ages. Please Aunt _____ I want to fuck you for real.”

My nephew wrapped his arms under my wife and cupped her ass in his hands as he took her neck in her mouth and his round muscled butt began to move between her legs, rubbing his dick on his aunt’s crotch.
At this point I was about to push the door open and intervene when I heard a soft but distinctive moan emanate from my wife’s mouth. A knot seemed to grip my gut that stopped me cold. The bedside lamp was the only light on in the room as I saw a tangible surrender sweep over my wife; her hands pressed into his back and her legs curled around his thighs. He covered her mouth with his in a deep kiss. His left hand gripped her panties and pushed them over her flared hips, down her legs, tossing them on the floor.
Gripping her waist he turned my wife on top of him and moved her up to where he could take her left breast into his mouth and suck it. Her hands were on either side of his head as he nibbled tongued and sucked first the left then the right nipple. My wife groaned, lifting her head up in pleasure she saw my reflection in the dressing table mirror just across from her and directly opposite the door. We locked eyes and something happened. An eerie eroticism was palatable between us. In that moment she knew that if she wanted to fuck our nephew she could to her lust’s content. I would allow it and would be fine.
She did.

My nephew kissed and sucked my wife’s tits like it was a rare treat. Holding her asscheeks he moved his right hand to her moist pussy and eased his middle finger into her, gently moving it around. She moaned as she moved her ass back on his hand, encouraging him to push deeper.

Our nephew was the starting first baseman on his high school baseball team and his body showed it. He was 5’10” and in excellent shape. His dick was at full mast and rubbing against my wife’s upper right thigh, it had to be every bit of eight inches but what struck me was its thickness. I was a bit over eight and a half but he was thicker than me by half.
I was rock hard and without thinking my right hand went into my shorts, gripping my cock.

My wife slowly moved down her nephew’s body kissing and licking, her hair draping over him as she took his dick into her left hand.

“Oh fuck _______, you have a really nice dick.” She took him in her mouth, tickling his balls with her fingernails.

She sucked him. Her head bobbed slowly up and down, making light slurping noises.
It was his turn to groan. In no time he took her head in both his hands as his hips moved up and down in rhythm to the one blowjob he would remember for the rest of his life.
This was incredible. My gorgeous wife’s ass was sticking up in the air as she knelt on the bed sucking off her big sister’s son. I knew that soon he would cum in her mouth and she would swallow it. She loved to swallow my wad, she would his.

He thrust his hips up and pumped his cum into her mouth as her held her head tightly, gripping her hair. My wife put her left middle finger into his anus and massaged, sending him over the edge. He grunted rather loud but I didn’t care, I was taking this in while stroking my own dick. She swallowed nearly all of his spunk, some did dribble out of her mouth and over the fingers of her right hand that was pumping his thick dick.

She rolled over when he finished and said:

“Eat my pussy, I`ll teach you how.”

He obeyed, moving around to put his head between her creamy thighs. My wife gave him a brief but thorough tutorial on pussy eating and with a little direction soon had her mewing as he sucked her clit and slipped a finger into her vaginal hole. In a few minutes she was cumming while at the same time smothering his head from squeezing her thighs.

He was rock hard again. My wife gripped his ears and pulled him up and over her. The teen aged boy scrambled over her body to comply.

Holding his ears her eyes bored into his, “Now do what you`ve always wanted to do. Fuck me really good.”

She took his pole in her right hand and guided him into her pussy. Her legs bent back as she opened herself up to his cock entering her. Our nephew held himself up by his hands as his ass began the rhythmic up and down motion between my wife’s legs. Her hands held his hips to guide his pumping.

“Motherfucker!” He breathed, “This is a goddamn dream!”

He fucked her with deep strokes, the sounds of her moaning, their hips slapping together, his ass clenching every time he drove into her, the sight of her feet splayed on the shaking bed as she met him thrust for thrust was sensory overload. I pumped my dick with a passion I never knew I had. I felt the boiling in my lower belly that every man recognizes as he’s about to explode. I braced myself with my left hand on the wood paneled hall.

“Oh shit, fuck me harder! Oh! Oh! Oh! Oh! Aaaaahhh! Fuckfuckfuckfuck!” Her legs clamped around his thighs and she thrust her hips up into him as she came….and came.
He lowered himself on her crushing her breasts and wrapping his arms behind her back he gripped her shoulders as if to hold her in place as he fucked his engorged cock in and out of her stretched out vagina.

“Oh my god Aunt ______! I`m gonna cum in you!” Still holding her in place he threw his head back then, lost in his own ecstasy he slowly shook his head back and forth while his dick gushed what proved to be a huge amount of cum into my wife’s womb.

In a moment my legs buckled as I began to pump my own geyser of jizz onto the hallway floor; I grunted like some sort of animal.
My nephew was draped over my wife but he heard my orgasm and spun around on her to stare at me in surprise. I was sitting on the floor with my back against the open door and my shorts stretched across my thighs. I raised my right hand to him in breathless communication that all was well. His dick made a wet popping sound as it pulled out of her pussy. The room was filled with the pungent smell of raw, incestuous sex.

My wife pulled his head into her breast and softly kissed his ear, “Its alright baby, its alright” she cooed.
