Lauren’s heart sped with anticipation as she watched Jason stand up and slowly pull down his zipper. The voluptuous, blonde thirty-nine year old realized it had been too long since the last time she’d had her eyes on a boldly exposed cock. As much as she loved watching all kinds of porn, it could never compare to the real thing, and she was already feeling the hot flush of excitement that her son’s eighteen year old friend was about to show off his cock. But of all the people she should be flirting and playing with, Jason was the last. Lauren hadn’t even met him until a couple of days before when he came to visit for a few days with Nico, her son, after finishing their first year of college.

As excited as she was, Lauren couldn’t help feeling a little ashamed of herself, too. At first, she’d been disappointed when Nico showed up with Jason, planning to have his friend stay a few days. The pretty blonde hadn’t seen her son very much over the school year, and she’d found herself missing him more than she ever expected. But Nico was out now, and Jason had made an excuse to stay behind, putting the horny visitor and Lauren on their own together in the house for the first time.

And now, Jason was pushing the band of his briefs down past his balls, allowing his semi-erect cock to swagger into view. Lauren’s audacious, young houseguest most definitely had a very nice cock. He was shaved smooth, with a nice, full ballsac and a thick shaft that looked like it would reach a decent length once he was fully aroused.

“It’s ... nice,” she told him haltingly.

“You like it?” he asked, pushing for more.

“I love it,” she said, only exaggerating a little. “Now let me see you stroke it.”

Jason grinned and took his bare cock in hand, stroking it in front of his friend’s mother and quickly bringing it to fully swollen state of hardness.

“You could always just stroke it for me,” Jason suggested, taking a cautious step closer to where Lauren was sitting on the living room sofa.

The blonde mother of one felt her breath catch. In reality, she would have loved to reach out and test the feel of that young, rock hard cock. She would have loved to stroke it until it was oozing precum and making the horny young stud moan with pleasure. She would have loved to tease and play with it until he rewarded her with a slick eruption of cum.

But Lauren had promised herself she wouldn’t go that far with her son’s friend. It was bad enough she already felt like she was cheating on Nico. This was totally irrational, of course, since her son was the last male on Earth she could ever have the kind of relationship with she wished they could have. She loved him more than she’d ever loved anyone, and she knew he felt the same way. She even knew he often snuck looks at her body. Maybe she was rounder and thicker than she used to be, but she kept her voluptuous figure firm and as well toned as she could. She had smooth, thick thighs and ass cheeks, and a full, round pair of C cup tits that many women envied.

Right now, Lauren’s body was beautifully displayed to Jason in a tightly clinging, white minidress that left her braless tits half bare. Jason’s eyes were roaming freely over her legs and tits as he stroked his aroused cock. He definitely had a nice one, she thought. A very nice one. But Nico’s was nicer. And bigger. Yet she knew she would never be able to see her own son in the same situation she was now seeing his horny friend. Even so, she couldn’t bring herself to touch Jason’s cock. Despite Lauren and Jason both promising to never let Nico know what they were doing, she still couldn’t keep the thought from her mind of how he’d feel if he ever knew. How could she ever look him in the eye again?

“Sorry,” she told Jason. “You have a really nice cock, but that wasn’t what we talked about. Besides, you said you like jerking off for older ladies.”

“I do,” Jason replied without skipping a stroke. “But it’s even better when they jerk it for me.”

Lauren just leaned back against the couch and watched Jason pump his swollen dick with his strong hand. She’d caught glimpses of Nice jerking off several times, but never like this. And now Jason was beginning to breathe heavily, soft grunts beginning to escape his throat. Lauren felt her nipples ache and swell in her dress as she gazed steadily at the younger man’s cock. She uncrossed her legs and left them open, but without exposing her panties. Then she began rubbing her nipples through the light material of her dress.

“Oh god, that’s hot,” Jason groaned. “Why don’t you take out your tits and let me really see them?”

“I guess looking would be okay,” the blonde replied as she pulled the spaghetti straps off her shoulders and yanked the top of her dress down below her full jugs.

“God, you have amazing tits,” Jason groaned.

Exposing her lush tits to the handsome eighteen year old, his wide-open eyes glued to her orbs while his fist rhythmically pumped his rigid cock, made Lauren’s pulse race faster. Her feeling of cheating on Nico grew deeper yet so did her unexpected level of arousal. The smoothly waxed slit between her thick thighs was growing warmer and damper by the second. It wasn’t long before she decided to let her thighs part wide enough to expose the crotch of her tiny panties. Then she pulled them aside to give Jason a look at her smooth, wet slit.

Lauren knew it was a bad thing to let her son’s friend see what her son never should, but she couldn’t control the hot quiver deep within her aching hole.

“You can come closer,” she told Jason. “You just can’t touch.”

Jason was beyond speaking anymore as he stepped into place right between Lauren’s widely parted feet. His eyes were all over her and his hand was pumping his thick rod harder and faster by the second. Lauren kept fondling her tits with one hand and slipped the other between her legs and began rubbing her wet slit, teasing her swollen clit as she watched the young stud pummel his rock hard meat.

Lauren was just about to shove a pair of fingers into her sodden pussy when Jason suddenly grunted and growled deeply, his big cock erupting in climax. Her young houseguest then spurted a generous load of cum that sent gobs of cream spattering her bared tits and her dress. Some landed on her thigh, dangerously close to her pussy. She could barely believe she just let her son’s college friend cum on her, yet a wave of dirty excitement took over while she pumped a pair of fingers in and out of her pussy. She rubbed on her clit at the same time while Jason stared at her, still standing over her with his cock in his hand. The orgasm ripped through her body until she was breathless and dazed.

The still breathless blonde mother hustled Jason off to the guest room where he was sleeping before he could say anything and then hurried upstairs to her own bedroom. She peeled off her cum spotted dress and wet panties, tossing them into her laundry hamper before getting into the shower. She shampooed and scrubbed her naked curves vigorously, as if she could scrub off the whole experience she’d just had.

Lauren took much longer than usual after her shower to dry her hair and get dressed again. It was her way of avoiding having to look Jason or Nico in the eye. Especially Jason. She couldn’t stop thinking about his cock, though, and how he’d looked and sounded while jerking his rod in front of her. At the same time she couldn’t stop thinking of how she just wanted to have some time alone with Nico. The weeks that went by without seeing him while he was going through his first year seemed interminable.

Nico was back by the time Lauren was dressed and refreshed and went back downstairs to make something for dinner. She could barely look either of the young men in the eye, and even started to feel annoyed that Jason was there at all. She needed to have time alone with the son she’d been missing so much. And then there was the terrible indiscretion with their guest earlier. Lauren was constantly aware of her son’s friend knowing what her naked tits looked like. Her naked pussy. He’d even seen her cum. She silently admonished herself at least a hundred times for letting it happen, yet every time she thought about his sturdy, young cock it threatened to make her slit drip into her panties.

She finally made an excuse to disappear back upstairs, and went to bed early, trying to distract herself bingeing on her favorite TV series. At some point, she could hear the boys talking downstairs with raised voices, but she couldn’t tell what they were saying.

The blonde finally fell into a fitful sleep, and was barely aware what time it was hours later when she became aware of someone in her bedroom. It was a warm night, but she still had the sheet pulled over her, yet the feeling of it being pulled off her body stirred her to a groggy state of consciousness. She found Jason standing by her bed in nothing but his boxer briefs, gazing down at the body he’d just exposed. Lauren was only wearing bikini panties and a cropped tank top that she only ever put on to sleep in. She was too groggy to think about trying to cover herself again, but when she saw the hard, fully swollen bulge in Jason’s briefs she suddenly felt wide awake.

“What are you doing in here?” the blonde said in a stage whisper. Her eyes were trained on her bold houseguest’s flat abs and the impressive bulge in his briefs.

“What do you think?” he replied in the same kind of whisper as he pulled the waistband of his briefs under his balls, liberating his swaggering cock. Then he gripped his shaft and began stroking slowly.

Lauren should have kicked him out of the room, but she didn’t. “You shouldn’t be in here,” she said. “What if my son wakes up?”

“I can’t help it. I’m leaving tomorrow and I just needed to look at you again.”

“I thought you were staying until Friday.”

“That was the plan, but Nico and I had an argument. He doesn’t like the way I look at you.”

“Hmmm, what makes you think I like it any better?”

“Because you get wet.”

Lauren didn’t like the idea of the argument her son must have had with his friend, but she felt relieved Jason would be leaving the next day. At the same time, she was excited to see him pull out his rigid cock and stroke it in front of her again. It made her think of Nico. Jason didn’t even matter to her, and it made her feel wicked to realize he didn’t have a clue. The blonde pulled off her top before Jason had a chance to ask.

“You like jerking off to my tits?” she asked her son’s friend.

“Oh yeah,” he told her. “I wanna fuck them like you can’t believe.”

“But you never will. You’ll just have to settle for looking and jerking off. And this is going to be the last time you’re ever going to see them.”

Jason just kept staring at Lauren’s full, naked tits, steadily stroking his rod while she sat up on the edge of her bed. She began playing with her orbs, fondling her flesh and twirling her nipples tightly between her fingers. Jason was breathing hard, and Lauren’s pussy was quickly seeping moisture into her panties.

“Oh god, just let me slide my cock between them once,” Jason begged.

“This is as much as you’re ever getting, you twisted little perv,” the blonde shot back in nasty tone.

Jason only seemed to get more excited by her insult, and he was soon pumping out squirts of spunk that landed all over Lauren’s tits. She started rubbing his warm cum over mounds before he was even finished shooting. She gave him enough time to squeeze out his full load of cum, and she was still playing with her tits when she simply said, “Goodbye, Jason,” in a dismissive tone.

Jason just tucked his now wet and spent cock back in his briefs and quietly left the room. Lauren lay back down in bed and slid off her panties. Her thick thighs parted wide while she slipped one hand onto her slit to rub at her wet lips while she held the other to her face and sniffed the pervasive odor of cum on her fingers.

Slipping a pair of fingers into her own, sodden hole, the voluptuous blonde replayed the last few moments in her mind. But instead of Jason, she saw her son in her mind. She couldn’t stop imagining Nico being so turned on by his own mother that he couldn’t stop himself from pulling out his excited cock and stroking it right in front of her. It wasn’t long before Lauren’s hot pussy was clenching and creaming all around her pumping fingers as the orgasm overtook her.

As she felt herself going back to sleep, she thought of how Nico would never do what Jason had. Jason was a crude, young pig with poor impulse control. Lauren had done a better job of raising her only son. He was more respectful. Sure, she caught him looking at her the way sons shouldn’t really be looking at their mothers, but he was too polite and refined to go sneaking into a woman’s room simply to jerk off on her tits. He certainly wouldn’t be doing that to Jason’s mother if they’d been staying at her house.

No. Nico was a good boy. Jason, obviously, wasn’t.

Lauren ended up sleeping later than usual, and she got up and took a shower before going downstairs. She took her time drying her hair and getting dressed. She put on a pair of light grey yoga pants and a short-sleeved jersey with a low-cut V neck that showed her cleavage. Her thoughts were all about Nico and how they finally had the house to themselves while she barely gave a thought to going without panties or a bra.

She was disappointed to discover that Nico must have gone out, leaving her on her own. The old beater car she helped him buy so he could get around at college was gone from the driveway. It would have been their first chance to spend some time alone since he got back, and she was also curious to know more about what happened between him and Jason. She hoped the other friends Nico was making at college weren’t like Jason.

Yet despite Jason’s selfish personality, Lauren had to admit the young man had a very nice cock. And it had been too long since she’d seen a naked one up close, especially one that was hard and swollen just for her. Not that she would’ve tolerated Jason’s obscene behavior any further than it had already gone. A guy like that would only want more and more every time, and he was the last sort of young man Lauren would give it to.

Nico was a completely different story, however. He was better looking than Jason, and of course a much more refined and courteous young man. And from what Lauren had seen of her son walking around the house in nothing but his snug briefs, he had a bigger cock than his friend, too. It was so terribly wrong, but Lauren was aching to see her son’s manhood in its full-fledged glory the more she thought about it. She’d been noticing her son’s impressive bulge since long before his obnoxious friend, Jason, came to visit.

Lauren wasn’t happy to find herself in an empty house. She’d had more than enough of that during the year that Nico was at school. She hoped it wasn’t going to be the type of summer where her son just came and went from the house as he pleased, acting like his still beautiful and sexually vital mother was little more than a friendly maid. Nor did she look forward to having the kind of summer they had just before her eighteen year old son left for college. His eager young eyes would roam all over her succulent curves, and the next thing she knew he’d be taking off and probably getting some local slut his own age to take care of his pent-up lust.

Lauren heaved a deep sigh of frustration. She was his mother. It wasn’t like she could be the one to relieve the pressure that built up in her handsome son’s balls. It didn’t matter how much her deeply private thoughts about pleasing his juicy young rod made her pussy quiver and ache. There was no point in feeling jealous of Nico’s girlfriends, but it was just one of those feelings she couldn’t control. At least she could look good for him and enjoy the harmless pleasure it gave her to catch him sneaking looks at her tits or legs.

Resigned to her frustrating situation, Lauren went into the kitchen and made herself a fruit salad for a late breakfast. She wasn’t pleased about not even knowing how much of the day she’d end up spending alone. Maybe she’d get together with her friend, Jasmine. Lauren and Jasmine had been friends for several years now. Both of them being single mothers about the same age to sons who were also the same age gave them plenty in common.

Jasmine was dark haired, and had a leaner, more petite build than Lauren, but the two often compared notes about the way their sons and friends were always checking them out. The other woman was incredibly bold when it came to teasing her son, and some of the things she admitted to Lauren made the blonde blush. But now, after what happened with Jason, Lauren had a story of her own that would surely make her devious friend blush. Then again, the other day Jasmine admitted to going out and buying brand new outfits just to wear around her son. Lauren almost wished she’d done the same thing.

She was thinking of calling her friend to tell her what happened with Jason, but the sound of Nico’s car pulling back into the driveway took her attention. Lauren was actually nervous to see him. She couldn’t help feeling guilty for what she let Jason do, and she wasn’t sure how she could face her son with that in the back of her mind. Could Nico know what they did? Was that why the two argued? Lauren decided to simply do her best to act as if nothing had happened. She was a grown woman, after all, and even if her son knew about her indiscretion what could he really say? It wasn’t as if she needed his permission.
