It was an unseasonably warm Friday in June when Kate Tomlinson got home from her job as a receptionist. Inside, she kicked off her heels and sauntered to the back patio where, as she suspected, she found her son in the pool doing laps naked.
“I thought I’d find you here.”
“Hi Mom!” Tom said, pausing his swim.
He looked her over, admiring her in her pencil skirt and silk blouse. And she knew well the effect that blouse had on her son ... as well as the men in her office.
“Join me, Mom!”
Kate smiled and started unbuttoning her blouse, full knowing her son loved these little strip teases. She tossed the blouse on a lounge chair, and as she freed her generous breasts from the constraint of her bra, her son watched, never tiring of seeing those tits fall free. She turned her back to him and unzipped her skirt, letting it fall to her feet. Last came her thong, and with it tossed aside, she walked to the pool steps and slowly slipped into the cool water, fully aware her son’s eyes were glued to her.
The two met in the shallow end of the pool, where he took his mother in his arms and kissed her sensually.
For nearly two years, the relationship between mother and son had grown far beyond the normal; they were lovers, and lovers of the most intimate kind.
“Long day, Mom?” he asked, taking a break from kissing her.
“Oh, the usual.”
“I still don’t understand why you work. I mean, Dad left you ... well us, with more than enough money.”
“True. I just like my job. I like meeting people.”
“And turning men’s heads!” her son teased.
“There’s just one head I like to turn.”
She kissed him, and he responded passionately. In his eyes, his mom was the most gorgeous woman he knew and loved their special relationship. And more, the fact that she doted on him, and that she was always ready to please him.
“Poor boy,” she teased, reaching for his crotch, “We didn’t make love yesterday.”
“You know I always want to make love to you, Mom!” Tom grinned before pulling her close and kissing her sloppily.
She could feel his manhood swelling when he lifted one of her ample breasts and started sucking on it.
“Oh, you naughty boy! You know what that does to me. But save it for tonight. I want to take you out to dinner.” Kate laughed.
She grabbed hold of his face and plunged her tongue into his mouth as compensation for his disappointment before heading for the pool steps, with Tom reluctantly following. She dried herself off with his towel while watching him emerge from the water with his semi-hard erection.
Handing him the towel, she purred, “I’ll make it up to you later. But there’s something I want to talk to you about. I’ll explain over dinner.”
Dressed again and appearing like a normal mother and son, Tom drove them to their favorite restaurant. One of Kate’s delights, since Tom had a driver’s license, was that he could be the designated driver, freeing her to enjoy alcohol to her heart’s content.
Over her wine, Kate started, “Now that you’re graduating high school next week, I thought I’d reward you with a trip to the Caribbean this summer.”
“Never been there.” he puzzled.
She leaned closer and, in a whispered tone, continued, “Your mother knows that. And I have a few good reasons. One, you will be of drinking age there, and I can indulge my lover with alcohol. And second, no one will know we are mother and son. For all anyone will know, I’m an older woman with a delectable boy-toy, and we can openly be lovers. Would you like to be my boy-toy?”
Tom simply grinned.
Back at home, they were barely in the door when Tom took his mother in his arms and kissed her, delicately at first, but soon pressing his tongue into her mouth, to which Kate reciprocated. After these two years, they had become as familiar with each other as any married couple.
Kate knew his weaknesses and led him to the sofa, prepared to indulge one of them. She unbuttoned her blouse then dispensed with her bra, freeing her pendulous breasts before sitting and inviting her son to sit beside her. After pulling off his T-shirt, he laid his head in her lap, where she held it, looking at him lovingly.
She leaned forward and offered up a tit, which he latched onto hungrily while his hand kneaded her other soft breast, as Kate uttered a gentle sigh. She always loved this sexy foreplay; blended with maternal nurturing made it extremely erotic for her. He continued making love to one tit or the other while his mother’s hand caressed his naked torso until she unbuckled his belt. Unzipping his jeans, Kate reached in and freed his growing erection, taking pleasure in feeling it in her hand.
His gentle moans, sucking on a tit while she stroked his cock, told of his need for release. Kate slipped off the sofa and finished getting him naked. Kneeling on the floor between his legs, she took a moment to admire his body. That summer, two years ago, it didn’t take long to overcome the social taboo of making love with her own son. And after two years of being lovers, Kate found him to be the most desirable man she ever knew.
She looked at her son seductively as she dragged her tongue up the length of his hard cock, rewarded by seeing him close his eyes and moaning. She ran her tongue up and down his shaft a few more times before slipping it into her mouth, eliciting another moan from him.
Kate knew her son’s libido well and knew after not cumming for two or three days he wouldn’t hold out long against her expert blowjob. She knew just how to play him, being able to make him cum fast or leave him on edge. She chose the latter and slowly made love to his cock.
He grabbed her head, instinctively encouraging her, but she continued sucking on his cock slowly until finally taking pity on him and started bobbing faster.
“Fuck, Mom!” he cried out as his cock erupted in her mouth, with Kate swallowing spurt after spurt.
She always liked giving head, but her son’s cock brought her delight to a new level. She loved making him cum – seeing him cum – with the feeling of his sperm in her mouth adding to it all. She loved to let some dribble down his shaft so that when his load was spent and she released his cock from her mouth, she could take a moment to admire his sperm dripping down his rod, touching it and feeling it on her fingers before licking it all clean.
It was Kate’s turn, and Tom pulled her onto the sofa before getting her skirt off, followed by the thong she knew he liked. Spreading her legs, he settled between them draping one over his shoulder and kissing a thigh.
“Oh, baby...” Kate hissed as his tongue slipped into her sheath.
Tom had also learned his mother’s buttons since they became lovers, and while a hand kneaded a soft breast, his tongue went to work pleasuring her clit. Kate’s fingers were running through his hair while he wound up her arousal until he had her on edge, then eased back. Kate grabbed at his head, gasping, while he left her on a precipice. She called out his name, begging him to release her, until finally, he dug in and ravaged her clit, sending her into a tumult of passion, her body tensing in ecstasy.
Finally, laughing with delight, she pulled his face to hers.
“Oh, my naughty boy!” she teased, pulling his wet face to hers for a sloppy kiss.
“I love doing that to you. You are so fucking hot when you’re like that.” he grinned.
Kate led her son to her bed—their bed these many nights. And as she knew he would be, the eighteen-year-old’s manhood was ready for more action, and she knelt on the bed, letting him take her from behind. He slipped his cock into her welcoming sheath and started pounding her while his mother clung onto a pillow, feeling every thrust of her virile son.
Two days of not having him inside her played on Kate as well. She could never imagine tiring of being fucked by her son; and she was willing to be the object of his sexual needs for as long as he wanted.
But Tom also knew his mother and what she liked. After enjoying fucking her from behind a while, he rolled her over and took her missionary style, looking her in the eyes as his rod slid deep into her womanhood. He knew just the effect it had on her, and she looked at him wide-eyed while he started driving his cock in and out.
And it was true; she never felt so intensely bonded to him as when they made love eye-to-eye. He took his time kissing her lovingly or looking at her adoringly while his cock made love to her pussy leisurely. And it was that look of love in his eyes that sent Kate’s emotions soaring, and she wrapped her arms around him in encouragement.
“Do it!” she hissed, while Tom fucked her with increased passion.
“Mom!” he groaned when his cock finally unleased its load in her sheath.
Despite being lovers for two years, having her son come inside her always triggered runaway feelings in Kate, and as often happened, knowing he was filling her womb with his sperm, she experienced another intense orgasm.
After, she caressed her son while he rested his head in her neck, his cock slowly retreating from the embrace of her sheath. He rolled off of his mom and snuggled beside her, an arm draped over her, cupping a breast, with both enjoying this moment of post-coital bliss. Kate knew her son’s libido could be coaxed for one more round, but she decided to enjoy just lying next to him, knowing a leisurely Saturday was in store.
It was also at these times that they broke into conversation.
“What happened to that cute girl you were dating?” Kate started.
“Denise? Didn’t work out. Had some hangups. I went down on her a couple times, but she was only willing to jerk me off once.”
“You know you can always bring them here.”
“That’s where we made out! But that was as far as she was willing to go. Besides, I have the best lover in you!” he replied before kissing his mother passionately.
“But I want you to explore women. My god, I’m still the only woman you’ve ever really fucked!”
“Because you’re the best fuck ever!” he grinned, squeezing her tit to make his point.
“But I think you should explore other women, your age, hopefully.”
“There’s a lot to be said for older women!” Tom laughed, letting his hand glide up and down his mother’s body to make his point before continuing, “But why are you so interested in me seeing other women?”
“There’s a word for it, ‘compersion’: taking pleasure from seeing one’s lover enjoying making love to someone else.”
“And you? If you find some hot guy, would you like to fuck him?”
“You’re more than enough man for me. In any case, at my age the chances are not like yours.”
“Mom, you’re forty-three ... and a MILF!”
“I’m glad my son thinks so.”
Tom pulled his mother close, and they kissed tenderly for a while longer before preparing for sleep. Tom slipped back into his mother’s bed, and as she had these many nights, Kate drifted off to sleep in the delight of her son’s embrace.
Saturday morning, as so often happened, they languished in bed kissing and caressing. For Kate, this was the most perfect time, and her feelings for her son were never stronger. Despite being only eighteen, he had the sensitivity of a much more mature lover, no doubt helped by his being her lover for two years.
The kissing grew passionate, and hands were soon between each other’s legs, with Tom fingering his mother’s wet slit, while Kate stroked his stiff erection. After a whisper in his ear, Tom mounted his mother, looking into her eyes as his cock slipped into her awaiting sheath.
Kate surrendered herself to the joy of having him inside her again, with her son fucking her slowly while he kissed her lovingly. Their lovemaking continued some time, never changing position, with Kate lost to the world, loving being in union with her beloved son.
But his tempo started increasing, and Kate grabbed his ass, encouraging him to drive his cock deeper. Finally, with a grunt, Tom came, flooding his mother’s womb with his seed, while Kate’s own orgasm soon followed, her body convulsing in ecstasy. It was another incredible climax, something that still amazed Kate. There was something about making love to her son that was unlike anything she experienced with any other lover, particularly when he came inside her. It was why she stopped dating; no lover ever made her feel this way.
When her climax ended, Kate opened her eyes as she caught her breath and found Tom looking at her with that look that sent her emotions soaring.
“I love you, Mom.” he whispered.
She pressed his head to her neck, feeling overwhelmed by the moment.
The two of them eventually climbed out of bed and showered together, another chance to be affectionate, with skin pressed against skin and lips to lips.
The two were enjoying breakfast, with Tom in just boxer shorts and Kate in a silk robe, when her phone rang. It was her good friend Allison.
“Allison! How have you been doing?”
“Oh, okay. I was hoping we could get together for a chat.” Allison replied.
“Yes! It’s been too long. Come for lunch.” Kate insisted.
Kate knew that her friend was having a tough time lately, having just separated from her husband, and after hanging up, turned to her son.
“I know you like swimming naked, but wear a bathing suit; Allison is stopping by for lunch.”
After Tom acknowledged his mother, Kate started thinking. She knew Allison was sexually frustrated, but there was one young man who could help. Then again, Kate questioned whether she could broach the subject of mother-son love. But it was a tempting idea to suggest Allison’s sixteen-year-old son Greg, and the idea of the joys of the double love a mother and son can share.
“Tom, what do you think of Allison?”
“She’s nice.”
“You know what I mean. Is she attractive?”
“I mean, yeah, she is a MILF.”
“That’s what I thought. She’s been rather sexually frustrated lately, now that her husband is out of the picture. And like me, she has a nice son right at home.”
“And sixteen, like I was when we first made love.” he reminded her before adding, “And last time I talked to him, we both admitted we had hot moms! Don’t worry, I didn’t tell him I’m sleeping in your bed.”
“And fucking me every day!” Kate smirked. “But that’s good to know. Now I just have to figure out how to broach the subject with her.”
“Gonna tell her about us?”
“Maybe ... Likely. I’ll have to play it by ear.”
It was turning into a warm day when Kate greeted Allison at the door.
“As you can imagine, Tom is in the pool already. Come out to the patio.”
Tom was doing some laps when the women sat at the patio table.
“Tom has turned into quite a handsome young man.” Allison said, watching him.
“Yes, he has.” Kate smiled. “Now, how are you doing.”
“I’ve decided to divorce Steve. I know he’ll just cheat on me again. Thank goodness for Greg. He’s become more responsible now that his father is out of the house. He seems to have become the man of the house.
“Now I have to think about the dating scene. Like I told you, the last two years have been rather sexually frustrating with Steve. Now it’s cold turkey.”
It was what Kate expected to hear. The question was, would she take the bait.
“How about you? Any prospects?” Allison asked.
Kate was ambivalent, claiming she had a couple of dates that went nowhere. The conversation turned to men and dating and what Allison wanted.
“Do you want romance or a fuck buddy at this point?” Kate asked.
“To be honest, I’d settle for a tryst, if he knows how to treat a woman, that is. Romance may be too much to ask for. Besides, I’m not sure I’m ready for that at the moment.”
Kate saw the opportunity had come to make her pitch.
“Well, there is an option close to home, if you know what I mean.”
It took a moment for the meaning to register, and a look of shock fell on Allison’s face.
“Have you ever thought about making love to Greg?”
The flustered look on Allison’s face spoke more of embarrassment than shock, and Kate suspected she hit at a kernel of truth.
“Oh, I think plenty of mothers have that feeling. They just suppress it.” Kate continued.
Allison turned to Tom, still doing laps, then back to Kate, a look of incredulity on her face.
“I know what you’re thinking. Can you keep a secret? Yes, Tom and I are lovers and have been almost two years now.”
“Your own son?” Allison exclaimed, barely able to keep her voice down.
“Yes. Sounds shocking, I know. But it’s been the most wonderful experience of my life, and I can’t imagine a more perfect lover.”
Tom had just hauled himself out of the pool and was drying himself off, while Allison stared at him blankly, trying to collect her thoughts.
“He is handsome, isn’t he? And by your reaction, I suspect the thought of Greg has crossed your mind.” Kate continued.
“Um ... Well ... I mean, idly, I confess. But I would never act on it.”
“I felt that way too. But after my divorce we grew closer, which didn’t help with my feelings. Then I realized he felt the same. Didn’t take long before cuddling on the sofa turned into kissing sessions, then nature took its course. And any sense of societal guilt was washed away by our feelings for each other. Since then, we’ve only grown closer.”
By this time, Tom was coming to join them, with Allison admiring his Speedos as he sat in the chair next to his mother.
“I just told Allison about us. And I suggested she had her own potential lover right at home.” Kate grinned.
“Even if I wanted to, I could never approach Greg! I mean, he may not want to.” Allison protested.
“Oh, I think he does.” Tom interjected. “Last time I talked to him, I got him to admit he thought you were hot.”
“‘If’, you wanted to, test the waters. Wear sexy things around him. Find excuses to get close to him. I think you’ll find out quickly if he’s interested.”
“But Kate, shouldn’t Tom be seeing girls his own age?”
“Yes. Sometimes I want him all to myself. But sometimes I feel like he should date girls and told him so. So, I leave it up to Tom. He’s free to date girls if he wants, and he does sometimes.”
“Thing is, Mom’s the best lover. I mean ... well, sex with her is better than I can imagine with any girls from school.” Tom added.
Allison probed for more and received far more intimate facts about their relationship than she expected.
Finally, Allison suggested it was time to head home, and Kate walked her to her car.
“If you do, um, move ahead, my advice is to forget those social taboos. As you can see, I derive great pleasure from being truly intimate with Tom. Frankly, it’s why I’ve stopped dating. Sex with him more than fulfills me.” Kate smiled.
After seeing Allison drive off, Kate returned to the pool, where Tom greeted her with a kiss.
“All that talk got me going.” Tom grinned.
Kate was always willing to gratify her son and pulled down his Speedos. She pushed him to sit on a lounge chair then stripped herself. With little ceremony, she knelt by him and started sucking on his growing erection. She truly delighted in pleasuring him, and was soon bobbing on his cock while he held her head, sighing with delight. And after five minutes or so, Tom’s passion hit the breaking point and came in his mother’s mouth, with her happily swallowing his load.
She gave him a wry grin then jumped into the pool, with Tom soon following. They kissed and hugged in the water, with Tom wanting to pleasure her right then. But Kate suggested he wait until they retired to bed that evening. So, the conversation turned to Allison.
“Think she’ll do it?” Tom asked.
“Maybe ... Likely, judging by how she reacted today.” Kate laughed before resuming kissing her son.
Allison arrived home and found Greg watching his favorite baseball team on TV, a regular passion of his. She paused for a moment to look at him. Yes, he was becoming a handsome man, and that Kate zeroed in on her secret fantasy made Allison wonder if she really could act on them.
“How’s the game?” she asked.
“Seventh inning, we’re down by three.” he said nonchalantly.
Allison sat next to him, more interested in human contact than the game. After half an inning, she rested her head on his shoulder, and to her delight, he put his arm around her. They stayed this way until the game ended. But for Allison, it just heightened her feelings, blurred between her motherly love and her need for intimacy.
The end of the game broke the spell, and the two went about their Saturday as usual until dinner.
“Why are you looking at me like that?” Greg asked.
“What? Oh, uh, just appreciating my handsome son, that’s all.” Allison said nervously on having her thoughts disrupted.
She realized at that moment, her idyl fantasy was taking form, and her mind altered between being shocked by it, and the thrill of thinking about the possibility.
Sunday, another game was on TV, and Greg settled on the sofa to watch. A short while later, his mother came into the living room wearing a bikini.
“It’s lovely out. I’m going to catch some rays. If you get tired of the game, come join me.” Allison smiled.
Greg just stared a moment. He always thought his mother was beautiful, and in that bikini, even more so. She was tall, with Greg finally growing taller than her in the last year. And with her long blonde hair and slim figure, most would not believe she just turned forty. Plus, there was one thing he couldn’t take his eyes off of. Allison’s breasts weren’t big, but they were enough to give her an eye-catching cleavage, which her bikini only enhanced.
“Oh, um, okay Mom.” Greg replied on catching himself.
Allison sauntered to the patio door, quite aware of her son’s reaction, then settled in a lounge chair with a book to enjoy the warm sun. About an hour later, Greg came out to join her.
“A blowout, nine to one. Not worth watching, so I thought I’d join you.” he explained.
“I’m glad! Sit here!” she replied, pointing at the lounge chair next to her.
But Greg just paused a moment to let his eyes drink in his mom, lying quite languidly, like some bikini-clad fashion model.
“My, how you’ve started to have a life of your own lately. So your poor old mom appreciates you spending time with me.”
“Mom! No one could possibly think you’re old!”
“Well, I’m glad my son thinks so.”
Allison broached a subject they hadn’t talked about in a while.
“I haven’t heard about your love life in a while,” she asked casually.
“What? Oh, well, Tracy and I kinda drifted apart.”
“Sorry to hear that. How far did you get with her?”
“What?”
“You know you can always confide in me. If you want, that is.” Allison said reassuringly.
“I guess ... that was the problem. I guess I pushed a little too much. We never got past kissing.”
“Well, she is sixteen. And you have a sixteen-year-old boy’s libido. You just have to learn to be patient. Oh, would you mind doing my back?” she added, turning over and handing Greg the sunscreen.
He took the bottle and sat on her chair.
“Let me make it easier.” she said, untying her top and exposing her bare back.
“Mmm, that feels nice. Do my legs too.” she murmured as he slathered her with lotion.
By time he was done, Greg could feel his crotch stirring and settled back in his chair, hoping his bulge wasn’t obvious.
The subject was dropped, and the rest of the day continued like any other Sunday.
Monday, Allison arrived home from work and found Greg in the kitchen preparing dinner, then came up behind him, giving him a tight hug.
“I have a wonderful son! You’ve cooked more dinners in the last month than your father ever did in our whole marriage!” she beamed.
He turned to her, and Allison kissed her son on the lips, letting them linger just a bit, followed by Greg blushing.
“What? Can’t a mother kiss her son on the lips from time to time?” she teased.
Greg smiled nervously before returning to his cooking.
Tuesday, Allison decided to do some shopping on the way home then stopped for some takeout.
“Here, set the table. But I want your opinion on something. I’ll be back!”
She set off for her room while Greg prepared the takeout, and a few minutes later she reappeared in a sexy, one-piece dress that showed off her cleavage to full advantage, with it and the stilettoes enhancing her long legs.
“Seeing how I’ll be back on the dating scene, I wanted something for the right man. What do you think?”
“Wow, Mom,” he could only say, looking her up and down.
It was just the effect she hoped for, admitting to herself he was that ‘right man.’ She stepped up to him and took him in her arms.
“With these heels, I’m just a bit taller than you again.” she teased, followed by another kiss on the lips.
She wore the dress through dinner, secretly excited by his difficulty trying not to look at her cleavage.
After, Greg apologized that there was a game on and wanted to watch, with Allison asking if she could join him.
As he turned on the TV, she kicked off her heels and curled up beside him, resting her head on his shoulder while the game started.
“Hope you don’t mind, but I like these little opportunities to be with my son.” she whispered.
“No.” he replied, putting his arm around her like the last time.
As the game progressed, Allison could not help but notice his furtive glances at her, making her feel sexier than she had in years.
Finally, the game ended, and she turned to him.
“That was exciting.”
His lips were right there, and the way her son looked at her made her feel the moment was right. She delicately pressed her lips to his, letting them linger some time. She could feel her face flush with excitement, and she half expected him to get aggressive, but he simply accepted her kiss.
She looked into his eyes, which conveyed his being pleased, encouraging her to kiss him again, this time with the kiss growing more sensual as both enjoyed it. The kiss lasted quite a while until Allison broke it off.
“I don’t see anything wrong with a mother kissing her son.” she reaffirmed.
But Allison felt the need to collect herself and bid him good night before asking if there was another game the next night. She could see the perplexed look on Greg’s face before heading to her room. After stripping and slipping into bed, she realized everything was heading in the right direction and she wondered if she could really seduce her own son. It felt as if forces were irresistibly drawing her in that direction.
Wednesday, Allison wanted to relax, and changed into shorts and a T-shirt before the two of them made dinner. Again, she curled up on the sofa next to Greg as the game began. This time, she idly caressed his chest with a hand as they watched. And at one break in the action, she turned to him, planting her lips on his again. And Greg responded without hesitation, kissing her back with equal, if not more enthusiasm.
Allison let him watch the game when it resumed. But at each break they kissed, with her snuggling closer while she could feel his growing confidence in his kisses.
When the game finally ended, Allison gave her son one last lingering kiss.
“There’s nothing wrong with us showing our love by kissing.” she smiled before saying good night.
Later, lying in her bed naked, Allison couldn’t help but rub her pussy, thinking about what just happened. And as she brought herself to a climax, she knew this had to progress.
Thursday was much like the last. But Allison put on a braless tank top, knowing the effect it would have, which was confirmed over dinner, with Greg unable to take his eyes off her nipples poking through her top. With another game on, again they snuggled on the sofa, but all pretense of watching ended as they spent more time kissing than watching, tongues probing each other’s mouths while hands explored each other’s bodies.
Allison could sense he was hesitant to touch her breasts. But her hand landed on his lap, unable to miss the bulge in his crotch. As she continued to kiss him, she was unable to resist rubbing the erection growing in his shorts. After some time, she could feel he was quite hard, and temptation got the better of her.
She pulled off his T-shirt, letting her hand trace his chest. Next, she unzipped his shorts before reaching in and finding his manhood. Allison pulled it out and took a deep breath as she admired her son’s erection for the first time. Greg could hardly control his own breath as his mother started stroking his stiff rod. Nothing was said between them, but Allison became fascinated at feeling his hard cock in her hand.
