High Infidelity

I shouldn't have done it. After all, she's my son's girlfriend. But from the first time Danny brought Abby over to the house, there was something palpable between us. When he introduced us and we shook hands, we held each other's gaze for an inordinately long time as she gave me a warm smile.

"So nice to meet you, Mr. Harwood."

"Likewise, Abby," I replied, "and please, call me David."

It was a hot, muggy, late spring day and they had come over to cool off in my pool. The place Danny shared with some guys just off campus had no AC, nor did the basement suite Abby rented. I poured them some lemonade and we sat on the deck off the kitchen chatting, mostly about how their university studies were going. Danny was just completing his MBA and Abby was working on her Master's in sociology. I took her all in as we talked. She had a quiet confidence about her, blessed with a keen mind and a sense of humour. She seemed unaware of her delicate beauty: Her shimmering brunette hair and bright blue eyes, her gorgeous face and radiant smile. There was a wholesomeness about her coupled with a simmering sensuality that made her very alluring. Not the sort of woman you would call a bombshell, but rather a woman with a subtle attractiveness that sneaks up on you. A man my age should not have such carnal thoughts about any woman young enough to be his daughter, let alone his son's girlfriend. But I think any adult male with a pulse would react in the same way.

She and Danny changed to go for a dip. When she came out wearing a white one-piece suit, my heart almost stopped. I discreetly checked out her supple young body - round, firm, breasts without a hint of a sag; a slim waist, well proportioned womanly hips and lithe, athletic legs leading up to a rock-hard ass accentuated by the high cut of her suit. Danny told me she was a fitness buff, and clearly she was in great shape. If she weren't a diminutive 5'4" I'm sure she could be a model. (That height thing is something I'll never understand about the high fashion business. Why do they insist that the models be so tall? But I admit I'm biased - I like my women on the small side.)

My boy is punching above his weight, I thought to myself, staring at her ass as she walked out the door to the pool. He's a great kid and super-smart like his mother, but a touch on the nerdy side and not terribly athletic. He was on the track team in high school- a good long-distance runner - but has that lanky runner's build and has never seen the inside of a weight room, despite my encouragement. I was a rugby player in college and, at just over six feet and 200 lbs, I still keep myself in pretty decent shape. People tell me I look and act younger than my 48 years. I married Danny's mother when we were both too young and I got pregnant with Danny, and our union was never a particularly happy one. We did our best raising Danny together, but as we grew apart I developed a wandering eye and had the unfortunate habit of seeking validation in the arms (and pussies) of young, nubile women. One of them was a fresh-out-of-school personal assistant I hired, who was soon providing me with very personal assistance indeed. She was a great fuck with an 'anytime, anywhere' attitude. That, along with my marriage, ended when my wife dropped by my office early one evening and caught me balls-deep in her pussy with her bent over my desk. Not long after my wife moved out to the coast, lured there by the offer of a senior research position at a prestigious college, leaving me with the house and a large mortgage and not much else.

In hindsight it was for the best, and the timing couldn't have been better. My import-export business took off thanks to a niche I found in the EU tariff system that allowed me to import certain goods from Asia and ship them directly off the Europe. I'm now in a very comfortable position financially. I have a small management and sales team and the business practically runs itself, which leaves me with lots of free time to indulge in my favourite pastime, namely the pursuit of pleasures of the flesh. I admit that I am an unabashed pussy-hound. At this stage of my life I lean towards dating women at least 20 years my junior, mostly because I still can. They tend to be less clingy and more sexually adventurous and in better shape than women closer to my age. I don't think of them as young anymore, just firm. And lots of them are easily impressed by my confidence and money and fancy car and special edition motorcycle. There's nothing like a ride on the back of my bike followed by champagne and caviar by the pool to get a girl to slide off her bikini bottoms, spread her legs and welcome my cock into her tight, clingy cunt. But at the first hint that they want to get serious I move on, telling them I'm just too old for them.

I tried to dismiss my obsession with Abby, telling myself that our mutual attraction was a product of my imagination, the musings of a lustful middle-aged man. And besides, she was my son's girlfriend, a no-fly zone, and I had plenty of other women to choose from. But the more she came over with Danny to hang out, the more I was drawn to her. There was something ethereal about her, an indescribable charm that made me long to be with her, to just grab her and rip her panties off and spread her legs and feel her writhe under me as I fuck her. Without thinking I started to modify my behaviour, working out more, buying some new clothes, making sure I had no women hanging around when I knew she and Danny would be stopping by.

Things between us evolved slowly. We always greeted each other with a warm hug, and sometimes I would slide my hand down and gently caress her hip, then her butt. She never moved my hand away. We always found some time to chat alone, without Danny being present. We stood a little too close, speaking in low tones, making lots of eye contact, talking about food and music and movies. Occasionally she would touch my shoulder or put her hand on my chest, if only briefly. When she and Danny stayed over, she started walking around in the mornings wearing nothing but panties and one of Danny's t-shirts, her nipples poking through. From time to time I'd get a glimpse of her camel-toe through her tight, sheer panties, her plump pussy lips taunting me, beckoning my cock. Once she caught me staring at her crotch and gave me a wry smile instead of a scowl. Another time the converse happened and I noticed her glancing down at the bulge in my tight cycling shorts when I came home from a ride. She turned beet red but it was my turn to smile. I left to change before she saw me spring a woody.

As our comfort with each other grew, Abby started asking me to apply sunscreen to her back when she was sunning by the pool, always when Danny got up to go in the house or run an errand. He seemed oblivious to it all. The timing was not lost on me, nor was the fact that she was inviting me to have somewhat intimate physical contact with her. To my mind this clearly fell into the category of overt cock-teasing, but I was quite happy to be her personal pool boy. I got fairly bold about it, undoing her bikini top, coming close to the sides of her breasts as I rubbed the lotion in, slipping my fingers into the waistband of her panties to cover her tan line, rubbing the lotion in slowly, lingering too long. She never objected. One time I boldly ventured south and rubbed sunscreen slowly and sensually over the exposed portions of her gorgeous ass cheeks. I continued down to her legs and as I rubbed her inner thighs she spread them slightly and I rubbed her pussy briefly. She moaned softly and I saw a wet patch grow in her gusset. Needless to say, my dick got rock hard. When I was done I jumped in the pool to hide my throbbing erection just as she turned to say thanks. I'm sure she knew what I was up to. "Getting hot out here" I told her. "Yes it is" she replied, giving me a smile. If Danny weren't around, I'm pretty sure I could have fucked her then and there.

Sometimes at night when she stayed over I would stand outside Danny's room and listen to them fuck: the pounding of the headboard against the wall, their moans and grunts coming through the door, the familiar slapping of flesh on flesh. I was tormented by their rutting, happy for Danny but filled with a mixture of lust and envy. I would usually take it out on one of my fuck-buddies living close by in a late-night booty call, savagely pounding her as I imagined it was Abby's pussy that I was plowing. Other times I would simply jerk off to a porn video starring a model who reminded me of her.

The game-changer came when the three of us were lounging by the pool one lazy Sunday. Danny went in to get some drinks and she jumped in to cool off. As she climbed out I saw that her skimpy bikini top was askew, her right breast spilling out, fully exposed. She looked down and noticed it and, instead of trying to cover up, she turned to face me fully and, looking directly into my eyes, unhooked her top, giving me an unobstructed view of her beautiful breasts. "Oops" she said smiling at me as she dangled the top in her hand for a few seconds, showing off her spectacular tits before slowly tying it back up and adjusting it, tucking her girls back in. Danny came back out just as she finished. I threw a towel over my lap to cover up my hard-on. She gave me a wink and held her finger to her lips, telling me this would be our little secret. From that moment on I was confident that it would only be a matter of time before I would have the chance to get into her pants. I also knew I would not be able to resist.

It happened not long after when Danny was away with some of his pals for a boys' weekend. It was another hot, sunny day and Abby texted me asking if she could stop by to use the pool. Of course I said yes. This was her visit to my place solo, and I was pleased that she felt comfortable enough with me to come over even though Danny wasn't around. I was filled with carnal thoughts but tried to put them aside, reminding myself that she was my son's girlfriend. She went to his old room to change and came into the kitchen wearing a very skimpy bikini, cobalt blue to match her eyes, two triangles attached by strings for a top and t-back bottom, basically showing off her entire ass. She gave me a little twirl and asked me if I liked her new suit. I got hard instantly. I didn't try to hide my arousal as I moved in. I took her head in my hands and forcefully kissed her. She resisted at first and tried to push me away, saying "No, we can't. Danny. he's your son..." but then folded into me. Our tongues entwined and probed each other's mouths as I groped her ass. She ground against my throbbing cock and then, stepping back slightly, unzipped me, pushing my shorts and boxer briefs to the floor. I quickly stripped off her bikini and cupped her hairless pussy, sliding a finger between her folds, feeling her wetness. Wordlessly she dropped to her knees and started to blow me, licking my balls, running her tongue up and down my rigid shaft before taking me in her mouth, sucking and licking and bobbing up and down as she pumped my dick with one hand and fondled my balls with the other. After months of lusting after her it was too much for me and I almost came immediately. But I wanted to savour the moment, to feel my cock in her pussy. I stripped off my t-shirt, pulled her to her feet and pushed her onto her back on the kitchen table with her ass on the edge. I spread her legs and rested them on my broad shoulders and rubbed the head of my cock up and down her sopping pink slit. I plunged into her unceremoniously and watched her tits bounce rhythmically as I pistoned in and out of her young, tight cunt with my thick cock, stretching her out. The sight of Abby's pussy lips clenching and milking my cock was almost too much for me, so I stopped thrusting vigorously and ground my pelvis into hers in circles to stimulate her clit while delaying my release. I fondled her tits, pulling gently on her nipples, telling her how wet and tight her pussy felt. "Fuck me" she said, "I want your cock". I resumed pounding into her and, to my relief, she came quickly, her body writhing as she moaned in ecstasy. That triggered my own orgasm and with one final thrust deep into her I found my blissful release, pumping rope after rope of cum into her. I let go of her legs and leaned in and kissed her as I brushed her hair off her face.

I helped her to her feet and took her hand and led her to my bedroom, leaving our clothes strewn about the kitchen. As we lay facing each other, I told her that I had wanted to do that for a long time. She told me she did too, that she was drawn to me from the first time we met, and knew that I felt likewise. She said she's always had a thing for older men and she knew it would happen sooner or later. She really wanted me to fuck her the day I got handsy with the sunscreen, but of course couldn't do anything with Danny around. She told me she came over with the specific intent of finally fucking me. She also admitted she pranced around the house in her t-shirt and panties to tease me, to make me lust after her, that flashing me her camel-toe was quite deliberate. I told her she was a shameless little cock-tease, but I was flattered that she took an interest in an old fart like me.

"I'm mostly interested in this," she said as she started stroking my cock. She pushed me on my back and made her way down south and took my dick in her mouth. She soon had me hard again and, straddling me, pointed my cock at here opening and lowered herself onto me. She started slowly at first, grinding into me and riding me up and down.

"Do you like my sweet little co-ed cunt? Is it as tight and pretty as you imagined it would be? Do you like watching my pussy lips wrapped around your fat cock? Can you feel me milking you?"

"Yes..." was all I could say in response as I grabbed her hips and thrust up into her. She put her fucked me back. I could sense her orgasm building.

"That's it. Fuck me with that big daddy cock. Fuck your son's slut girlfriend. Make me your little whore. Don't stop!"

She stopped humping me and she screamed as her torso spasmed with pleasure. She paused and collapsed on top of me, kissing me deeply. With my dick still inside her I rolled us over and resumed my thrusting.

"You love to fuck, don't you. Do you like my cock? Do you want me to cum in you again?"

"Yes, David, fuck me! Give it to me. Fuck my pussy and give me your cum".

And with that I exploded for a second time, emptying my balls into her.

We fucked and licked and sucked seemingly non-stop that weekend, exploring each other's bodies. (Thankfully I had some help from the little blue pill, which I took while freshening up after our second session. I don't generally need it at my age, other than to overcome the occasional bout of whisky-dick, but I was glad to have it on hand for this epic fuck-fest of a weekend.) I had truly never met a woman who could cum as often and as hard as she could. She was not shy at all about sex, telling me she wanted to try different positions, to do to her whatever I wanted. What's a gentleman to do? I fucked her every which way: rimming and finger-fucking her, rubbing her g-spot while I licked her clit; pulling her into me by her arms as I fucked her roughly doggy-style; more cowgirl and reverse cowgirl, which we both loved because I could last forever in those positions and she could grind into me and control the action on here way to multiple orgasms. I fucked her mouth and she hungrily swallowed my load. I bounced her up and down on my cock in the shower (one reason I love small women). She really got off on watching us in the mirrored wall of my gym in the basement, telling me she felt like a porn star as I fucked her on the weight bench.

She told me to talk dirty to her. I called her every filthy name under the sun: cock-hungry slut, cheating little whore, fuck puppet, cum-guzzler. She loved all of it, lost in a frenzy of lust. I too was in a frenzy, just trying to keep up and keep it up. Call me amoral, but I felt no guilt that I was using my son's hot young girlfriend as my personal fuck-toy; and neither, apparently, did she. She insisted that I fuck her in Danny's bed, and even wiped our juices off my cock and her cunt with one of his t-shirts that he keeps at the house. So nasty, so forbidden, so deliciously bad.

Between our fuck sessions we sat naked and ate mostly take-out meals -- thank you, Uber Eats -- and got to know each other. She knew most of my history, including the fling with my assistant leading to my divorce. She said Danny told her he was bitter about it at first but had gotten over it. And she was aware of my bevy of women, seemingly untroubled that I might consider her just another notch on my bedpost. She lost her father at a young age (which I already knew). Her mother never remarried but had lots of boyfriends and was unashamed about having men stay over, telling Abby and her sister that she had 'needs'. I wondered if that was why Abby had what I would call a healthy attitude toward sex.

Unsolicited, Abby went into surprising detail about her own sexual history. It was as if she had a compulsion to talk about it. She told me about how she lost her virginity at eighteen to the father of her best friend, when he took the girls to the family's lake house for a week. He had always been friendly with her as she grew into womanhood, complimenting here appearance, giving her fatherly hugs, checking her out when he thought she wasn't looking. She, in turn, found him attractive and charming for an older man and enjoyed his attention. The first night he fixed them some mixed alcoholic drinks (the drinking age was 18 where they lived, so it was legal), telling them they were basically adults now and it was cool as long as they didn't tell their mothers. Her friend seemed to get drunk quickly and they put her to bed early, leaving Abby alone with the dad. He sat on the couch with her, told her she was a beautiful young woman and kissed her. With the liquor relaxing her inhibitions, she responded. He slid his hand into her pants and fingered her tight, wet hole, something no one had ever done before. He placed her hand on his hard cock and asked her if she wanted to see it. She nodded yes. He took her down to the boathouse where she let him strip her naked, the first time a man had even seen her nude. He laid her on a foam mattress, slipped on a condom, spread her legs and had his way with her tight teenage pussy. She said he was gentle enough but she didn't cum. I told her it all sounded kind of creepy (ignoring how creepy I was being in that very moment.) She agreed that it was, but she was more than ready to lose her V-card and was glad it happened. She realized that he had carefully planned the whole thing, overserving his daughter while making Abby's drinks weaker, and having a box of condoms at the ready on a shelf in the boathouse. He fucked her every night that week and a few times during the day when his daughter was in the shower. Abby was a willing participant and started to orgasm as he licked her and fucked her. She took a cock into her mouth for the first time and was disgusted when he held her head still and came in her mouth without warning. She spit out his jizz as he handed her a bottle of water. He apologized but told her she would need to learn to swallow if she wanted to keep her future boyfriends happy. By the end of the week she had.

Her friend wondered why Abby was always so tired during the day, not realizing that she was up getting railed by the dad every night. She knew her friend would be mortified and furious and feel utterly betrayed if she learned that Abby was fucking her dad, that together they was cheating on her mom. For some reason Abby found this enthralling: a nasty, dark secret kept from her best friend -- it was all so taboo to her.
