As tired and sore as she felt, Holly was excited with the way the bookshop she inherited from her father was coming along. Several months before, a massive stroke took him without warning. He was barely sixty, and she decided to make some renovations and keep his business going. She was also expanding to include a café and also opening up a small part of the second floor to expand the retail space her father had only used for storage. There was still plenty of storage space in the building’s basement, plus the rented unit her father had had for several years.

Holly’s father had been a purveyor of rare books for an elite clientele, and having grown up working with him in his shop and at auctions over the years, she was well prepared to keep the business going. There were also a number of college campuses in the area that brought in a lot of cash business. She was sorry to leave behind a fifteen year career as a highly sought after massage therapist, but she was planning to keep a small selection of clients just to keep her hands in shape.

Her twenty year old son, Quinn, had volunteered to transfer to a university close to home so he could help with renovations and the day to day operations after reopening. Holly only agreed to this as long as it didn’t interfere with his studies. Luckily, the renovations and opening were all happening while Quinn was on summer break. He’d been her savior these last few weeks, using his skills to paint and do repairs.

For Holly, it was reminiscence of the past and excitement for the future all at once. Working around the shop in her tank tops and tight denim shorts that didn’t fully cover her ass reminded her of those wonderful days she used to tease her father unmercifully. She’d always been a loving and devoted daughter and she had frequent fantasies about letting her handsome, affectionate dad have his way with her eager pussy. He’d always resisted anything more than the generously sexy view his busty, athletically built daughter happily offered. That, and some overly long hugs that bordered on inappropriate for a father and daughter.

Teasing men had always come easily to her, but Holly always loved showing off for her daddy the most. It was simultaneously the naughtiest and most loving thing she’d ever done. She had slightly thick, strong looking thighs with an ass that matched perfectly. Her tits were even bigger now, bordering on D or E cups, and they were still shapely and firm enough that a lot of people thought they were fake. Instead of being insulted, Holly took that as a compliment. She was thankful for having DNA that kept her looking closer to thirty than her real age of forty.

She missed her father deeply, but now her son, tall, gorgeous and built like a ripped Adonis, was paying the same kind of attention her father had. Or more accurately, trying to pretend not to. It made her feel so alive to see the bold admiration in his eyes and the long, sweaty days working together had been making her giddy with happiness. It was heavenly to have him back in her life on a daily basis and she couldn’t help burning up with pride every time she looked at him. She’d even started to imagine a few of the same kinds of naughty fantasies about her son that she used to have about her father.

It was wrong, of course, but what harm was there in a few dirty daydreams? Given her father’s history of restraint, there was never a chance of her crossing a line she could never cross back over. Part of her was actually relieved, doubting if she could ever go through with anything more. Those were bittersweet memories, but with Quinn back at her side every day she was already making new ones.

It was now late in the day on a Wednesday. The grand opening had already been advertised for Saturday. With an old friend she trusted to work with on board to manage the café, everything was ready. Late that afternoon, Quinn came down from the second level to find his beautiful, blonde mother standing by herself, admiring all their hard work.

“Hey Mom, how about we go over to Grandpa’s storage unit tomorrow and pull out a few boxes of stock? There’s still a couple of bare shelves upstairs and it’ll look better if we’re fully stocked.”

“Good idea, baby. Let’s go in the morning. But not too early, okay? After all this work I can use a couple easy days before the opening.”

Quinn smiled and nodded. “You’re the boss, Mom,” he said with a proud smile. Then he suddenly scooped his voluptuous mother into his powerful arms and hugged her close, crushing her sweaty melons to his body through both their damp shirts. “I’m so proud of you,” he added. “You’re ... just incredible.”

“Aw, baby, I’m proud of you too. This wouldn’t be happening without you. You’re the best thing that ever happened to this old lady.”

“Uh, Mom. News flash. You’re not old. You know all my friends say you’re the hottest MILF in town.”

“Ha!” she blushed, trying to laugh off his unexpected compliment. But deep down she couldn’t have been more pleased. Then her eyes narrowed and she gave him a sultry look. “And what do you say?”

Quinn smiled a guilty smile. “Let’s just say I never disagreed with them.”

Holly felt her nipples tingle with sensation. Her son’s evasive confession put a coy smile on her face. They were both damp with sweat and the material of their tops felt tacky in between where Quinn’s big, hard body crushed up against his mother’s voluminous melons. But it felt disturbingly good, reminding her of all those nice, close hugs with Daddy, and they held on much longer than any average mother/son embrace. Holly could feel her son was in no more of a hurry to break contact than she was.

“That means you agreed with them,” she pointed out suggestively.

“I didn’t say that. Not exactly,” he replied, starting to blush.

Holly loved seeing her son get flustered almost as much as she loved holding on to his solid, manly body.

“It’s okay if you think that, baby,” she told him. “It means a lot more coming from you than anyone else. It feels good to think you might approve of your old mom.”

“Oh, I definitely approve, Mom. And then some.”

Holly could sense something stirring inside the crotch of her son’s shorts, right up against her body. She realized he was getting hard and felt her heartrate practically double. This was already new territory for the voluptuous mom since her father had never flirted that openly with her, although she did feel him start to get a hard on sometimes when they hugged. She was now dying to grind on her son’s growing cock, but she was briefly frozen with self-doubt and he was backing off before she knew it. Quinn’s face was red as a beet as he pushed away, embarrassed by his erection. Her breath stopped for a few seconds when she spotted the size of the bulge in his shorts. She didn’t know whether to be relieved or disappointed by his pulling away.

“Geeze, Mom, we’re both all sweaty and gross,” he said, quickly changing the subject.

“Sorry, baby, you’re right. Let’s go home and take a shower.”

When she realized it almost sounded like she was suggesting they shower together, Holly started blushing as hard as her son. She also realized she liked the way it felt with them both being overheated and sweaty. There was something primal about it. It probably would’ve felt gross with anyone else, but with her son Holly felt nothing but happiness and delicious tingles all through her luscious body. And Quinn’s growing cock proved he didn’t think it was gross at all.

They finally locked up the shop and Quinn drove them home in his mother’s SUV. When they got to the house they went upstairs to their separate bedrooms. Holly had an en suite bathroom while her son normally used the extra one at the end of the upstairs hallway. She started to undress, watching herself in the mirror on the bathroom door as she pulled her damp tank top over her head, tossing it aside. Her hair was still tied back in a high ponytail while her tits stood out heavy and proud. Her nipples were swollen and she spent a moment twirling them with her fingers as she thought back to that long, loving hug she had with Quinn back in the shop.

Holly knew perfectly well that her tits were spectacular. She wasn’t conceited, just being objective. People had been staring at them for years and she was proud of the way they’d held up to time. Oh, it wasn’t like she was that old yet, but compared to her son she almost felt that way sometimes. She studied them in her mirror while cupping and kneading them with both hands. She started to feel sweaty all over again as she thought of how Quinn responded when she squished her full orbs against his brick wall of a body.

She wished he hadn’t backed away just when his cock was starting to get hard. The poor boy had no idea how much that made her feel loved and desirable. But she could’ve been more forward, too, if only she’d been braver. She could’ve ground against his bulge to see his reaction. She could’ve made her dirty love for him so much more obvious.

Yet she was at fault too. All those times with Daddy, and today with Quinn, she didn’t have the courage to take that ultimate risk. A woman who’d always loved cocks and sex, she still couldn’t explain why she’d been wired with these special feelings for her father and now her son. Teasing other men into giving her cock had always been so easy for her that it barely meant anything. It felt good, but was never anything memorable. Was it a blessing or a curse? Her love and desire were so exhilarating it felt more like a blessing, yet a terrible curse to never to have either of the only two men to ever make her juices flow like a river of honey.

Holly didn’t want the same thing that happened with her father to happen with her son. She was sure he’d been getting hard for her. His growing cock had made that obvious. She was consumed with the need to know if her own son would throb with need for her if only he had the right conditions to reveal his desire. It didn’t even matter if either of them could bring themselves to cross the ultimate line. She just needed to know.

And she had just the way to test these choppy waters.

Holly took off her shorts, leaving on her sweaty thong panties that were all damp and dewy in the gusset. She threw on a fresh tank top that was cropped a mere inch or so below the swell of her luscious tits. She plumped her nipples once more before leaving her room and going to Quinn’s door. She found him stripped down to only his boxer briefs. His body was so beautifully chiseled, his blonde hair a shade or two darker than hers and cut short. And that bulge in his briefs looked so impressive she could barely catch her breath.

Quinn spotted his scantily clad mother in the doorway and smiled. He liked what he saw and didn’t mind that she was seeing him now in only a tight pair of briefs. Being at home in their underwear had been a normal practice for them for years, but there was an edgier feeling in the air this time.

“What’s up, Mom?”

“Say, sweetie, how about a massage? You must have some pretty tight muscles after all the work you’ve been doing. We don’t want to risk any sprains or injuries. It would be my way of saying thank you for all your help. And if we do it now then neither of us has to shower twice.”

Quinn stretched his enviably defined body. “Now that you mention it, I do feel pretty tight, and my lower back could use a little loosening up, if you really don’t mind.”

“Of course not, baby, that’s why I offered.” She gave him a thousand watt smile. “I hope you know what a lucky boy you are to have a professional masseuse for a mother.”

“Oh, I do, trust me,” he grinned.

Quinn had never been big on team sports, but he’d been lifting weights for a few years already and ran regularly. Holly had given him massages many times before, but usually concentrating on areas where he’d strained a muscle, rarely his full body, and so far, only while he was lying on his stomach. But tonight, she was going to give him more than he’d ever had before.

There was a third bedroom where Holly kept a massage table and collection of oils and lotions. She only took care of a few clients at her house, more often going to their houses or physical therapy centers. She was expecting the look of surprise on her son’s face when she went back to her bedroom instead of her massage room.

“I don’t feel like setting up the table, honey, if you don’t mind. I’ll just lay some towels out on my bed for you. How’s that?”

Quinn seemed curious but told his mother he didn’t mind at all. He stood there in his skintight briefs while she laid out the towels and fetched a bottle of oil from the massage room. Having been through this before, he crawled onto his mother’s bed and lay on his stomach. Holly grabbed the waistband of her son’s briefs and gave it a couple of tugs.

“Let’s get these off you, sweetie. With all the work you’ve been doing, it’s only right to give you a proper massage,” she told him, her voice nearly cracking with nerves.

“Are you sure?”

“C’mon, big boy, get ‘em off,” she said.

“Geeze,” her son chuckled. Without turning over, he lifted his ass and started to push his briefs down. His mother took over and pulled them down the lower part of his legs and off.

As she gazed at the hard perfection of Quinn’s legs, ass and back, Holly started to wonder about the wisdom of her idea. With her clients, she normally covered their asses with a towel, which would be repositioned over their cocks when they turned over. Though most of her male clients were hard as a rock by the time she got to the front. Happy ending massages weren’t Holly’s profession, but she did enjoy finishing off some of those hard ones on occasion, when she liked what she saw. Only a couple of her clients ended up coming back for those special massages exclusively, and they tipped her generously. Those were two of the clients she’d decided to keep.

But now, seeing her son’s gorgeously ripped body laid out naked on her bed was making the lips of her motherly pussy quiver. She didn’t know if she’d be able to speak without giving away the catch in her breath. She wondered if any other woman in the world ever felt the intense love and pride that was flowing through her now.

“This is really nice of you, Mom,” Quinn said, breaking her reverie, then closing his eyes and settling down comfortably.

This brought his mother back to reality.

“My pleasure, honey,” she said, meaning it in a way he couldn’t possibly imagine. If he only knew how strong her pulse felt in her pussy right now.

The blonde hesitated a moment or two, but then she took off her top. Quinn was oblivious to the fact that one of the hottest MILFs he or his friends ever saw was now standing behind him in nothing but a sweaty thong. She smiled and nearly giggled out loud, but then she oiled her hands and started on his feet and calves, kneading her fingers into his muscles and gliding her palms over his warm skin. Just running her hands over his strong legs, feeling his solid warmth made Holly’s nipples ache with sensation.

She knelt on the bed between his lower legs as her hands worked their way higher on his thighs, moving toward his spherical ass. That was when she looked up and caught her reflection in the mirror on the bathroom door. She almost looked naked, except for her tiny, well-worn panties. Her tits billowed up between her arms as she worked her hands into the meat of her son’s ass cheeks. She almost froze a moment when she realized if Quinn opened his eyes he could easily glance toward the mirror and catch his mother practically naked as she massaged him. What would he think? Would it make him hard? Was he already getting hard as she kneaded his ass and spread him apart just to sneak a naughty peek at his tightly puckered hole?

Holly’s mind was spinning, and it only got worse when Quinn started to sigh and moan out loud with pleasure. He usually moaned when his mother massaged him but it was a much throatier sound this time. He must he getting hard, she thought. She could see his balls jutting down between his legs but his cock was tucked under him, out of sight, making her ache to see it that much more. A simple look wouldn’t be that bad, would it? She’d now seen his balls and rimhole. She loved the extra closeness it made her feel to him and it was only a little bit against the rules.

Since Quinn had mentioned his lower back, Holly concentrated extra time there, yet her oily hands were spending at least as much time kneading his ass. And every time she pulled him open far enough to see his asshole she yearned to touch it, rub it with the pads of her fingers. She wondered what he’d do if she dared push a careful finger up inside his hole. It was a filthy, sinful thought that was making her snatch feel like a furnace inside.

“You really are awfully stiff,” she said suggestively, making a token effort to massage his lower back, but her hands were back on his ass within seconds. The extra husky tone of her voice wasn’t lost on her.

“Mmmm, I am, Mom. So stiff you wouldn’t believe it,” he said, halfway groaning.

“Mommy will always make you feel better when it’s stiff,” she said recklessly. “I mean ... when you’re stiff.”

Holly glanced at the mirror and saw Quinn’s eyes were open now. He was staring at her image in the mirror. His eyes were glaring with lustful awe. She knew he had to be surprised to discover her topless, but he looked completely enrapt by the sight of her.

“What if it’s you that makes me stiff, Mom?” he said.

“Then I should always be the one to make it feel better, baby.” As she watched him gaze at her big, naked tits in the mirror, Holly finally felt the courage to reach down and fondle her son’s heavy balls, making him groan deeply. “Does Mommy make you stiff, baby?” she asked.

“Yes, Mom. Really fucking stiff.”

She gasped dramatically. “You said the F word, sweetheart. That means it must be really bad. Do you get that way ‘cuz of Mommy a lot?”

“Every day, Mom. Sometimes multiple times in a day.”

The blonde was so surprised to hear this she had to wonder if he was telling the truth, but there was nothing but bare sincerity in his eyes.

“Awww, is it frustrating?” she asked, still caressing his balls.

“Very. I try to take care of it, but it always comes back. The stiffness, I mean.”

“Hmmm, there must lots of pretty girls at your college who’d love to help you relieve yourself.”

“There are, Mom. But...”

“Yes, baby?”

“They’re not you.”

“But they’re young, pretty college girls. I bet they must be so hot.”

“They’re okay. But none of them are as pretty as you. Or as hot or sexy as you. None of them make me as stiff as you do.”

Holly’s heart was racing. She made eye contact with her son in the mirror. “Let’s get started on the other side, sweetheart. Mommy can make the stiffness go away.”

She then got off the bed. Quinn watched in the mirror as she pushed her sodden panties down her legs. She couldn’t help giggling at the way his eyes lit up at the sight her perfectly smooth, bald pussy. She got back on the bed and straddled his knees again.

“C’mon, baby. Roll over and let Mommy make it better.”

“Are you sure?”

“As long as you are, too, I’ve never been more sure of anything, my love.”

Quinn carefully rolled onto his back, doing his best to keep the towels under him while his mother’s legs gave him a limited range of motion. Holly gasped involuntarily when his beautiful cock came into view, standing up so long, thick and proud against his body. Holly made a token effort at massaging her son’s arms and chest, as if she were still giving him a regular massage, but it wasn’t long before her oily hands worked their way to his throbbing stalk and cum-heavy balls.

“Ohhhh, Mom mmmmm, fuuuck,” Quinn moaned, barely above his breath. “I can’t believe you’re really doing this.”

“Neither can I, baby. But I’m not sorry, are you?”

“Nnnnhhhh, fuck no.”

Holly giggled, pleased with her boy’s reply.

“I never knew how big and beautiful it is, darling.” The stunning blonde was gazing in fascination at her son’s cock like she was trying to memorize every contour and vein. “You’ve been keeping a biiiiig secret from Mommy,” she added with a giggle.

Quinn almost laughed but it ended up coming out as a groan while his mother’s slick hands wrapped around his hot shaft, squeezing and stroking his meat. Holly was entranced by the sight of that beautiful cock in her hands. The one she was never ever meant to touch, yet the one she always wanted deep down in the furthest reaches of her secret soul.

“It’s like a piece of sculpture,” she said softly, as if talking to herself as her thumbs slipped over the sap-oozing head. Holding onto Quinn’s cock, Holly scooted further up his legs, until her pussy came into contact with his balls. He was shaved as smooth as she was, allowing her to savor the full pleasure of his warm skin against hers. She whimpered when his ballsac squished against her mound. Then she held his shaft up against her body, holding him right up to her lower abs. “Oh god, baby, that’s how far inside me you’d go if we ... ya know ... oh god, if we actually fucked.”

With Quinn’s cock well oiled from his mother’s stroking, she placed one hand over the head and moved him back and forth against her skin like a windshield wiper blade, smearing more moisture on her body. She kept watching her hands and that cock, trancelike, barely noticing his big hands moving to her hips and rubbing from there along her thighs. Her pussy was broiling now. Churning with hot need. Her flowing juices were soaking his smooth ballsac and she couldn’t resist gently grinding her slit over his balls while she kept rubbing his stalk back and forth on her skin.

Holly couldn’t believe she had her boy’s fabulous cock so close to her pussy. She was dying to know how it felt inside her, but as much as she’d imagined incestuous love with her father and now her son, something was holding her back. It was a raging swirl of doubts and fears. Yet her clit was demanding to feel more.

She let Quinn’s cock rest back against his abs and moved up just a little higher, so she could trap his shank against him with her slit. She had his meat firmly trapped right within her dripping furrow. Then she started rocking her hips, sliding her twat up and down her son’s enormous shaft. The sensation was exquisite and Quinn’s moans were enough to prove he was taking as much pleasure from their forbidden contact as she. He was watching the bob and sway of her luscious tits as she rocked. She leaned forward, bringing her melons closer to him.

“Feel them, baby. I know you want to. Feel Mommy’s big tits,” she cooed lovingly.

Holly moaned in approval when Quinn began massaging her weighty orbs with his strong hands. He paid loving attention to her aching nipples, and with her clit rubbing over the shaft of his cock she knew she’d find her delirious release before long. It was crazy to think she was more aroused now than she’d ever been before with any other man’s cock actually pumping inside her. It was the next best thing to actually fucking each other, and maybe they wouldn’t have any regrets later.

“Mom, fuck, ohhh Mom, if you don’t stop you’re gonna make me ... Ahhhhhhhhhh!!!”

The end of Quinn’s sentence came out of his huge cock in the form of hard spurts of cum jetting up on his body.

“Yes, baby, yes!” Holly cried. “Cum for Mommy! You’re not inside me so it’s okay. It’s not wrong like this. Oh baby, oh god, there’s so much cum!”

Then Holly started to cum, too, grinding harder and faster along her baby’s shaft while the electric jolts of pleasure shot through every cell of her glorious body. She was mewling and crying while Quinn grunted like an animal, squeezing down harder on his mother’s tits until his pulsing cock was drained. Holly kept going through another orgasm before she slowed to a stop and took a good at the two of them. They were both soaked with sweat, massage oil, pussy juice and man spunk.

The dazed blonde felt like a character in a dream she was having. When they started to calm down, she got off of her son, deliberately dragging her cunt over the creamy spatters on his body. She felt so naughty thinking of her man-boy’s cum touching her maternal snatch. She felt amazing, though part of her deep inside felt relieved that she hadn’t taken his cock inside her. It was good he came when he did or she would’ve lost control and shoved him inside her. At least this way she could still claim she’d never fucked her own son. Yes, it was hot, erotic and so full of love, but it hadn’t been fucking. No matter how much and for how long she’d wanted that, it would’ve been horribly wrong. Coming that close gave her a new perspective on her sordid desires.

“Um, we’re both quite a mess,” she pointed out. “I’m going to take a shower and I’m sure you want one too.”

Holly locked herself into her bathroom. She started the water and could hear Quinn try the doorknob. But he was a smart, sensitive boy and knew his mother needed this time to herself so he left it at that. She took a long shower, shampooing, freshening the shave on her legs and pussy. Savoring the pleasure they shared. She didn’t regret resisting the need to take his cock inside her, but at the same time she asked herself why she hadn’t, even though she already knew the answer.

After drying her hair and slowly moisturizing her skin, Holly went back to her room. Quinn had picked up all the towels and left her bed in the same state it was in before. She slept naked that night, as she often did. She craved feeling him next to her, but she was tired and emotionally drained. Sleep came on quickly, and she didn’t wake up until the middle of the next morning.

Quinn gave his mother a loving hug and a cautious kiss on the cheek when she joined him in the kitchen for coffee and a light breakfast. She was thankful he didn’t say anything about the night before, but also a little disappointed. She knew he had to be thinking about it, though. How could he not be? The look in his eyes told her everything she needed to know. He damn well was thinking about it, and this morning he was looking at her in a way she’d never seen before. Her body went limp and she nearly faltered on her feet when she finally pinpointed what it was.

Her strapping Adonis of a son was looking at her like he owned her. There was a hint of doubt there, too. Uncertainty. The one thing that was missing from his attitude was regret. Holly could see he wasn’t the least bit sorry about what happened. If anything, the gleam in his eyes made her feel like his love for her had swelled even more, if such a thing were even possible. His look was enough to make her blush, yet neither of them mentioned the minor instance of mother and son sharing a mutual orgasm barely a dozen hours ago.

They sat down at the table and had their coffee and some fresh fruit.

“Are you still up for going to your grandfather’s storage unit?” she asked, forcing her voice to sound casual.

“Sure,” Quinn agreed quickly. “If we go right after breakfast, we can pull a few boxes of stock, go to the shop and get them shelved, and then we could be back home by early afternoon. Still plenty of time to kick back. And we’ll have all day tomorrow to chill by the pool before the grand opening.”

“As long as you don’t mind. I hate to take advantage of all your help. You’ve been doing so much. Are you sure you’re up for more?”

Quinn gave her wry smile. “Definitely. That, um, stiffness I was feeling last night is all better now.”

Holly almost spat out a mouthful of coffee, but she got it down and laughed it off. That’s as far as they went toward talking about the night before, but Holly felt incredibly pleased with herself for giving her son the kind of physical therapy they both really needed. She knew they would have to talk about things in depth before much more time went by.

Old habits die hard, so Holly decided to dress to impress after breakfast. She was also feeling hotter and more beautiful than she had in a long time and it felt good to express herself that way in front of her son. She pulled on light grey booty shorts without panties. Then a white sports bra that showed off her cleavage and a pink, sleeveless blouse. She didn’t bother to button the blouse but just tied it together right beneath the swell of her distracting tits. A pair of flat heeled sandals and she was ready to go.

Quinn was waiting for her downstairs. He was wearing a pair of board shorts and a fresh tank top that showed off his arms and shoulders to perfection. He drove Holly’s SUV to the storage facility. It was pretty well deserted on a weekday morning. He pulled up in front of the door to his grandfather’s unit.

Holly opened the garage style door and they went inside the shady stall. There were boxes of books stacked everywhere, mostly labeled according to their value. But in the rear corner of the stall, they discovered Holly’s father had an easy chair and table with a lamp plugged into the one electrical outlet. There was an open box on the opposite side of the chair that was full of tattered paperback books. The box was large and unlabeled.
