Hal sat at his desk, working through a long list of emails, when his phone buzzed. Glancing at the screen, he saw his wife, Carol's, name and immediately felt a pang of worry. He picked up the call, the bustling noise of the office fading into the background.
"Hey, honey," he said, trying to keep his voice steady.
"Hi, Hal," Carol replied, a twinge of concern in her voice, "We just left the doctor's office. They prescribed a new medication for Gavin, and the doctor thinks it could really help with his depression."
Gavin was their eighteen-year-old son with a bright future ahead of him, or at least that's what they and everyone used to think. Tall and lean, with a mop of dark hair that constantly fell into his hazel eyes, he had always been the life of any room he walked into. But over the past year, something had changed. The spark in his eyes had dimmed, and he had withdrawn into himself. It broke Hal's heart to see his once-vibrant son struggling with depression.
But Carol's words lifted some of the weight off Hal's shoulders..
"That's great news," he said, smiling.
"It is..." Carol agreed, but Hal sensed some hesitation in her voice, "though, the doctor did mention there are some potentially significant and... unusual... side-effects. I'm a little concerned about that."
Hal frowned, understanding her apprehension.
"Well, if this medication can help Gavin, we just need to be prepared to handle any side-effects. We'll do whatever it takes to help him through this."
Carol sighed softly, the sound of her exhale filling the silence between them.
"You're right. We'll manage it. We're stopping at the pharmacy now, see you at home later."
"Okay, love. See you later," Hal said, hanging up the phone, the last few hours of his workday having just gotten much better.
---
Hal drove home with a rare sense of optimism. The news about Gavin's new medication had lifted his spirits, and he couldn't help but hope that this might finally be the breakthrough they needed. The late afternoon sun bathed the neighborhood in a warm glow as he pulled into the driveway, parking next to Carol's car. He stepped out, feeling a lightness in his step that he hadn't felt in months.
Entering the house, Hal called out, "Carol? Gavin? I'm home!" but was met with silence. He frowned slightly, expecting them to be around.
As he took off his coat, he heard faint noises coming from the living room. His curiosity piqued, Hal walked toward the sound, the noises growing louder with each step: a thumping noise like furniture banging against the wall and a strange, wet, slapping sound.
Reaching the living room he turned the corner and froze, his eyes widening in shock at the scene before him. There was Gavin, his teenage son, naked from the waist down as he absolutely plowed Carol from behind.
Hal's jaw dropped, his mind slowing things down as it tried to process just what the fuck he was seeing. Carol, his wife of twenty years, was bent over the front of the couch with her pants at her ankles while his son, HER son, held her by the hips and humped her hard and fast.
Joining the thumping and thwapping noises he'd heard (and now understood) on the way in were short, exasperated gasps from Carol as Gavin fucked the wind out of her, and strange, animalistic grunts from Gavin as he swung his skinny hips into her, hard.
Carol's blouse was still on but hanging loosely, offering peeks of her soft, wobbling tits. Her full, round ass was quaking and rippling with every thrust from Gavin. Her head was hanging down, her hair disheveled.
It felt like eternity but was really only a few seconds of watching before Hal finally found his voice.
"W-what the fuck is going on?!" He stammered, the words catching in his throat.
Gavin looked at him first, with a cold, emotionless expression that gave Hal a chill in his spine. Carol's head popped up an instant later, looking frazzled and a bit dazed.
"H-h-hi, h-h-honey," she said, tripping over the words each time Gavin slammed into her, "I c-c-can expla-a-ain."
Hal registered her words but didn't know what to do with them. They were still fucking! He was standing right there and they were still fucking! And also, why the fuck were they fucking fucking?!
"WHY ARE YOU FUCKING??," demanded Hal. He would've added "my wife" or "our son" or "your mother" to the end of his question, but since all applied his brain couldn't pick one fast enough.
Carol adjusted herself into a slightly more upright position where Gavin's thrusts weren't shaking her whole body quite as much. She tried to wipe and blow the hair from her sweaty face, but it did little to help her disheveled appearance. Gavin didn't slow down at all and was still pounding his mom's pussy like her husband wasn't fifteen feet away.
"It's the new medication," said Carol, her voice relatively steady, "I told you the side effects were extreme."
It took Hal a few seconds to remember anything that had happened before he'd walked into this room, but the earlier phone call with his wife did eventually return to him.
"Side-ef... fucking... WHAT??" Hal shouted, confused and still shocked as hell.
"The doctor called it, ungh... hyper-virility," said Carol, grunting through a particularly deep thrust, "it's like a fugue state where the user is really, really, really really horny. He doesn't even know what he's d-doing, his body is just telling him to fuck anything that m-moves."
Hal's brow furrowed in disbelief. Hyper-virility? Doesn't know what he's doing? He'd believe it more if she'd said they both accidentally tripped and ended up in this position.
But as he looked again at Gavin's face, the vacant eyes, the almost bestial sneer, and the total lack of acknowledgment of Hal's presence, he knew that, some-fucking-how, what Carol was saying had to be true.
Gavin's head dipped to the side and he grunted before plowing into his mom's pussy even more forcefully than before, causing her to moan in... pain?
"So, like, right now? He... doesn't care that he's fuc- I mean, that you're his...?" Hal stammered out his words, not knowing what one should say when seeing one's wife getting used as a living sex toy by their own son.
"Apparently n-not. The doctor advised to k-keep him away from anyone that he m-might get too amorous with. I u-underestimated the strength of these m-meds, I guess," she said, her tits rocking back and forth as Gavin continued his assault.
"Well why doesn't he- why couldn't he- ... I mean, couldn't he just, y'know, masturbate?" said Hal, trying to logic his way out of his son plowing his wife.
"That's what the doctor suggested, but there's no reasoning with Gav in this state. Believe me, I've been trying," she said with a hint of annoyance, "and if you'll remember, it was YOU who said not to worry about the side-effects, that we'd help him through it."
Well, this was certainly the worst way Hal had ever been hoisted by his own petard: having his wife hoisted on their son's.
"So... what? He just fuc-... just has sex with you and he orgasms and then he's fine?" said Hal, though the pit in his stomach knew it wouldn't be that easy.
"I wish," said Carol, bracing herself as Gavin pawed at her big, hanging tits through her blouse, "this is round three and there's no s-signs of him slowing down."
Hal's heart skipped a beat.
"You've fucked him three times??" he shouted, losing what little composure he had left.
"No, the first time was a hand job. Twenty minutes after he took the meds he came up behind me in the kitchen and had his hands all over my ass and boobs. When I figured out what was going on, I offered the hand job to keep him from tearing my clothes off. He... came... pretty quickly, and A LOT, but it didn't stop him. He seemed to need more so I used my mouth on him the second time. He liked that more than the hand job and he came again, so I thought I was in the clear but he just kept tugging at my pants until I gave in. Now he's been fucking me like this for the last half-hour!"
Hal stood in stunned silence. So much to take in, and the rhythmic sound of his son's pelvis smacking against his wife's ass wasn't helping. The air was heavy with the musky scent of sex. He could... accept, that this was something that needed to happen, regrettable as it was. But he didn't think he could stomach being around it any longer.
"I..." he started, searching for the words, "I get it. Thank you, for looking after our son."
Carol gave him an unhappy sort of smile, a sign that she appreciated his words but knew how much the situation sucked.
"I think I'll just go upstairs, or go for a drive or something," said Hal, rubbing his eyes in the hope the image in front of him would be wiped away.
"Wait! Don't go!" said Carol, "I need you, WE need you close by in case something goes wrong. What if he hurts himself? I won't be able to handle him alone."
It seemed to Hal that she was handling him just fine, but he saw her point. Painful as it was for him, it was surely no walk in the park for her, either.
"Ok, I'll just, uh, sit down," said Hal, feeling awkward now that the heightened emotions of the situation were lowering.
He sat on the lounge chair across from the couch. From this angle, he was seeing a lot less of his wife and a lot more of his son's bare ass. It certainly wasn't top of mind, but he noted how muscular Gavin's legs and glutes were. His son had always been an athlete, and was now over six feet of lean muscle, with four inches of height on Hal himself.
Gavin gave one last, deep thrust into his mom's pussy, smacked her hard on the ass, and pulled his cock out of her. And Jesus, what a cock. Height wasn't the only place Gavin had four inches on his old man. Hal's eyes bugged out as he saw the thick, meaty pole slide out of his wife and bob around as Gavin flipped her over so she was laying on the sofa. Pushing her legs wide, he plunged that fat cock back into her with a wet THWOOP and a groan from Carol.
Gavin quickly resumed the pace with which he'd been fucking her doggy style. Her blouse had twisted so much that her boobs were practically falling out of it and Gavin finished the job, tearing the blouse slightly to get at his mom's milky jugs. He grabbed big handfuls and squeezed, kneaded, pinched and shook them, never slowing his ravaging of her pussy with that enormous cock.
Carol was breathing hard, from exertion Hal supposed. She was taking the brunt of one hell of a fucking.
"S-so..." she stammered through Gavin's humping, "h-how was your day?"
Perhaps never had something so banal been said in such an un-banal situation. It actually surprised Hal so much he was answering before he could recognize the absurdity of it.
"Umm, it was fine, I guess..." he said, watching Gavin's smooth, heavy ballsack slap against Carol's asshole, "actually there was one sort of interesting thing with the layout for the August catalogue. Do you remember I told you about that guy from the..."
Hal droned on about his work story, finding that it was distracting him from what was happening. Carol seemed to be listening intently at first, but not so intently the longer he went on. Hal watched as her eyes started to glaze over, then roll back into her head as a long, loud moan escaped from her chest.
"OOOOOHHHHHHFFFFUUUUUGGGGHHHHKKK!" she bellowed, her cheeks flushing, her legs shaking, her son pounding her cunt with his thick slab of man meat.
The moan was followed closely by a few light giggles, that Carol quickly swallowed as she regained some amount of control. Hal watched her face return to normal, his own wrinkling into a nauseous look of horror.
"Did... did you just have an orgasm on our son's cock?" he asked, more rudely than he probably should have but, well, there ya go.
"It's not my fault!" cried Carol defensively, "You try getting fucked like this for nearly an hour. Son or not, a few orgasms are going to slip through."
Hal choked on his own saliva. A few...?
A loud grunt from Gavin kept Hal from pursuing the thought. His son's pace was quickening, his fucking of his mom's soaking pussy getting more erratic. He stayed on edge for a long time, nearly a minute more, but the third orgasm he'd apparently been building toward erupted deep inside Carol's pussy, flooding her with molten cum as he smashed his pelvis into hers, trying his best to deliver it to her womb.
The rhythmic pounding that had led Hal to the room had finally stopped. He watched in awe, waiting to see what would happen now. Both Gavin and Carol were panting hard, catching their breath after the marathon session. Sweat glistened on their exposed skin and made what little clothes they still wore sticky and clingy. Gavin left his cock inside his mom for another minute or more, and Hal would occasionally see his balls tense, depositing more and more of his seed into her.
Eventually, Gavin retreated his hips and let his cock slide out of his mom with a PLOP. The creampie he'd left her followed in short order, oozing slowly from her opening like thick, melting ice cream.
"Is... is that it? Is it over?" asked Hal, hopeful that this nightmare was ending.
Carol was staring up at Gavin's face. His eyes were closed, his head dipped as he continued trying to catch his breath. His fat cock was still looking mostly erect, but not quite as dangerous as it had before.
Carol sat up on the couch, Gavin standing in front of her.
"I think he's-OOOP!" Carol was cut off as Gavin grabbed her by the back of the head and pushed her mouth down on his cock, which was quickly regaining its full strength.
"Shit" thought Hal, realizing the ordeal wasn't quite finished.
He watched for a couple minutes more as Gavin's face-fucking of Carol slowly turned into more of a vigorous blowjob as she recovered from her initial surprise and tried to get some control over him. He wouldn't let her stop or even slack off too much, and would grab her hair and pull her back down on his member anytime he seemed to feel she wasn't performing the task well enough.
"Igh fingk heeg's onnag nee juspa liggle bidt morghp," Carol said through a mouthful of her son's cock. Hal couldn't fully interpret but got the message anyway.
"I'm gonna get started on dinner," he said, rising to his feet, "I'll be just in the other room if you need me, and I'll check back as often as I can."
Carol's mouth was getting fucked again, so in lieu of a verbal response she gave a quick thumbs up to her husband before putting her hand back on Gavin's hip to try and steady his pace. Hal retreated from the room with the parting image of his son pushing his cock into his wife's throat.
The sounds of Carol sucking off their son, a mix of wet smacking noises and guttural gags, followed Hal into the kitchen. As he began pulling together ingredients for the family dinner, he did his best to push it from his mind. A shift in the noises from the other room a few minutes later sent him back in to check on them, finding Carol with her head down on the floor and her ass in the air as Gavin munched hungrily on her asshole. Her face was contorting as though she was trying (and failing) not to enjoy the sensation of his tongue deeply rimming her. Gavin was crouched behind her, his glossy eyes and the raging erection he was pumping with his fist a sign that this was more about his desire than her pleasure.
Hal left the room again, taking his time chopping some vegetables in the hopes they'd soon finish up. Around ten minutes later, he went to check on them again, finding Carol flat on the floor with Gavin reverse-straddling her face, his strong hands mashing her huge tits together as he jug-fucked her. He was playing with her tits, slapping them around as his fat, spit-coated cock penetrated her cleavage. His heavy balls dragged across her face in-time with his thrusting as Carol feebly stuck out her tongue to service them, licking his taint just as often. It seemed like this was heading in the direction of her being pressed into returning his rimjob favor, and watching his wife lick his son's asshole wasn't something Hal cared to see. He made a hasty retreat back to the kitchen.
The sound of Carol loudly exclaiming "No!" brought Hal hurrying back in a few minutes later. There he found Carol back on her knees with Gavin pounding her doggy style. Her eyes caught her husband's, seeing his look of concern.
"He tried to stick it in my ass," she said, a little shakily but with the nonchalance of someone who had just avoided spilling their coffee, "but I told him to do me in the pussy instead. He seems to respond if the request is made a certain way."
Hal noticed that though Gavin's cock was in her pussy, he had a thumb buried past the knuckle in her butthole, working slowly in and out. Carol turned her head slightly back toward him.
"That's it, fuck me in the pussy, baby," she said like a mother gently coaxing her son to, well, keep fucking her pussy and not her ass.
Hal walked back to the kitchen to finish the dinner, relieved (he guessed) that his son hadn't anally fucked his wife.
"Yet," he mumbled to himself. This was day one of god knows how long Gavin would be on this fucking medication. So many lines had already been crossed to appease him, it seemed like only a matter of time before more would be.
Hal shuddered at the thought, busying himself with the final bit of dinner prep.
Another ten minutes later, the food was ready and Hal prayed the rest of the family was ready to eat it. He was almost relieved as he re-entered the living room to find that Gavin was on his feet, rapidly jacking his cock as he aimed it at Carol's face as she knelt in front of him.
The look on Carol's face was one of accepting, even yearning, for her son to cum on her face. Hal could hardly hold it against her; she'd been trying to sate the sex-monster for hours now, and maybe this load of cum would be the one to finally do it.
Hal cleared his throat awkwardly.
"Dinner's ready," he announced quietly, suddenly feeling like he was intruding.
Carol glanced at him and gave a subtle nod of recognition. She was naked now, the tattered blouse having finally been chucked away. She was holding her heavy tits from beneath, offering their fleshy visage to Gavin, trying to entice him to coat her in jizz. Tentatively, as though knowing it might help but not sure if she ought to, Carol opened her mouth and stuck out her tongue.
That seemed to do it. Gavin's strokes became faster, his hand gripping his cock like a vice as his whole body tensed. Hal saw the veins in his arm and cock bulging, his breath becoming shallow and ragged. Carol's gaze was fixed on Gavin's dick, her eyes averting slightly as if she were looking at a grenade that was about to go off.
With a loud, primal groan, Gavin threw his head back and started to cum. His wad erupted from his angry cock in a thick, white stream, splattering across his mom's pretty face. Her lips, her cheeks, her tongue, her forehead; all were quickly coated in criss-crossing ropes of her son's hot spunk. A glob landed across her eye and another streaked through her hair. What didn't catch her face landed in a pooling mess on her round, sweaty tits.
It was a majestic, sweeping symphony of a cumshot that surpassed any Hal had seen in years of watching porn. Any two of the facials he'd given Carol during their marriage couldn't compete with the incredible volume of the load their son was frosting her with.
And yet it was not jealousy Hal felt, but relief. Surely, he thought, watching Gavin squeeze the last few spurts onto his mom's coated tongue, surely this was the end of it.
"Cagh youg geck megh ah towlruh?" mumbled Carol through a mouthful of her son's cum that she understandably didn't want to swallow.
"Oh, yeah, right," said Hal, snapping out of his trance. His wife needed a towel and neither of them wanted Gavin's cum covering her any longer than it had to.
Hal quickly made for the laundry room, sparing a glance back to confirm that Gavin's huge dick was, in fact, deflating. From a clean basket, Hal grabbed a washcloth, then thought better of it and grabbed a full bath towel knowing it wouldn't go to waste considering the enormity of Gavin's load.
He returned to the living room half-expecting to find his son fucking his wife again, but was relieved to see that Gavin was sprawled on the couch panting heavily and Carol, though still generously coated in his cum, had gotten to her feet.
Hal handed her the towel and she began methodically wiping the spunk off her face and chest. Some had dribbled down her tummy, threatening to link up with Gavin's earlier deposit which was still leaking out of her pussy.
"I think he's finished," said Carol, using a corner of the towel to scrape the cum from her hair, "this is the first time I've seen his c-... penis, soft since he took the pills."
Hal thought it appropriate, if a little absurd, that Carol was choosing to censor herself when talking about Gavin's dick. Having sex with it was a medical necessity, but this was still their kid they were talking about.
"How long is the medication supposed to last?" asked Hal, watching Gavin for any sign that he was returning to normal.
"It's meant to work on the depression for 24 hours. The doctor said the hyper-virility would be most prominent for the first 4-8 hours and eventually fade over the next few weeks," said Carol, carefully placing the soiled towel on the floor as she retrieved her scattered clothes.
"Weeks?! He'll be like this every day for weeks?!" exclaimed Hal, trying to wrap his brain around this becoming a regular thing.
"Or months, I can't remember," said Carol with a little sigh. Hal knew this had been an ordeal for her, but in fairness she had at least gotten some good-looking orgasms out of it.
Carol pulled on her panties, a sheer, pink set that softly displayed her trimmed pubic hair and the alluring curve of her ass crack. Her blouse was a lost cause and she seemed unwilling to sully her jeans with the dried cum she'd been unable to wipe from her inner thighs.
"He's still out of it," said Carol, directing Hal's eyes towards Gavin whose eyes still held a faraway glaze, "I'll take him upstairs to lie down, and then I have GOT to take a shower."
Holding her clothes in front of her to shield her tits and pussy, Carol took Gavin by the hand, standing him up and leading him out of the room. Gavin seemed casually interested in watching his mom's bouncing ass cheeks as he followed her.
"Are you hungry?" asked Hal, the smell of the food in the kitchen reminding him that he'd come in here to announce dinner.
"Starving," said Carol, beginning to climb the stairs with their son in tow, "I'll be down in a few minutes."
As Hal sat at the kitchen table, pushing food around his plate with his fork, a "few minutes" turned into ten. And though he wished it was even a surprise, he soon heard the unmistakable sound of bed springs creaking in rhythm coming from Gavin's room upstairs.
"Not finished yet, I guess," said Hal to himself as a pleasured wail from Carol rang out through the house.A few days passed and Hal was once again seated at the kitchen table, sipping some coffee and reflecting on all that had occurred that week. He couldn't sugar-coat it, the past three days had been difficult, to say the least.
That first day and night had been the worst. Walking in on his wife, Carol, getting fucked by their 18-year-old son, Gavin, was easily the most shocking and disturbing event of his life. The side-effect of Gavin's new depression medication had lasted for a full eight hours that day, turning him into a sex-crazed beast of a man who relentless fucked his own mother for the duration. Carol had practically limped into bed that night, having endured their son's non-stop pounding and fulfilling his every lust-fueled desire.
Hal hadn't asked Carol to confirm it, but from the noises they were making he'd counted three more loads of cum from Gavin before he was fully sated. And though he didn't exactly blame her, he was sure that he'd heard her have twice that many more orgasms during the ordeal. Son or not, he had fucked her good.
The morning of day two had literally been a night-and-day difference. When Gavin finally awoke, he had seemingly overcome the drug's nasty side-effect and it was now having its intended effect. Gavin was cheerful, talkative, and full of his old joy: a far cry from how he'd been during nearly a year in depression's cold grip. He was polite, helpful, and made them all laugh the way he always used to.
When asked, he told Hal and Carol that he had no memory of the latter half of the previous day and had assumed the medication had conked him out. Pressed, he said he had a very vague recollection of mom helping him with something, but he couldn't remember what.
"And that's how it's going to stay," said Carol to Hal, steadfastly. Gavin had just left to take a jog, something he hadn't done in months, giving Hal and his wife some time to debrief.
"I mean, some part of him HAS to know though, right?" said Hal, though even as he said it he doubted his words. He'd watched Gavin intently during their conversation, and there was no hint of a lie when he said he couldn't remember. No inkling of an idea that he'd spent half the prior day fucking his own mom.
Carol shook her head.
"He doesn't, and I don't like keeping it from him but it's for the best. Look how well the meds are working now. He's back to being himself. The hyper-virility is... intense... but if this is the payoff it's worth it, and he'd never keep taking the pills if he knew they made him... do... me," said Carol, choosing her words carefully.
Hal's possessive side wanted to disagree, still harboring some anger that his wife had and might continue to fuck someone else (their own son at that) but at the same time he had to agree with what she said. This past year had been hard on all of them, Gavin most of all. If these new meds gave them their son back then, well, maybe it was worth Carol getting her brains humped out on occasion.
And so around midday on day two when the time came for Gavin to take his next round of pills, both parents were in alignment. As expected, the side-effect had kicked in again and turned him into a raging sex beast. But instead of letting him overwhelm her, Carol simply lead him to his room and spent the next several hours... taking care of it. It was every bit as intense as the previous day, but Carol had discovered that the more accepting she was, the more willing or even eager that she could appear to him, the easier he was to handle. He was less rough, less wordlessly demanding. He was still practically an animal, but not quite as untamed.
Hal mostly tried to stay away from Gavin's room that day, though more than a few times during their nearly six-hour long fuck session his curiosity got the better of him and he took a peek.
What he saw was different each time, but with the same familiar theme of his son pounding the ever-loving shit out of his wife. Sometimes she'd be bent over the bed, getting backshots with her face buried in a pillow, screaming her way through an intense orgasm, her big ass rippling from the constant, heavy impact of Gavin's pelvis. Sometimes she'd be on her back, Gavin straddling her chest as he fucked her wobbling tits or slapped his sweaty cock on her face. Hal hadn't seen it, but according to Carol their son had more than once tried to squeeze his fat cock into her asshole, nearly succeeding if not for her redirecting him to a different hole. Carol didn't even do much anal with her husband's average-sized dick; he didn't even want to think about what their son's meaty dong would do to her tiny hole.
That second day, while his wife repeatedly drained their son, Hal had spent some time online researching this drug Gavin was on. Everything he found confirmed what he'd been told about it: in some male patients, it could induce intense sexual arousal often coupled with short-term memory loss. He found numerous reports of users who had felt compelled to masturbate half a dozen times or more when the pills kicked in, and even cases of guys who had intense sexual encounters with their wives or girlfriends while remembering little to none of it. Hal had found no mention, however, of a user being so horny that they'd fucked their own mother, but to be fair, who would share that kind of thing?
Day three was more of the same, with Gavin being delightfully happy and blissfully unaware of his repeated incestual activity. He took his medication around midday and kept his mom busy until just before dinner at 5:30. Carol found her rhythm that day, her body not only adjusting to the size of her son's cock (somewhat) but really starting to understand what he wanted in his sexual fugue state.
"The first couple of loads come pretty quick," she had told her Husband that evening, "He gets impatient during handjobs but if I use my mouth I can usually get him to cum twice and avoid some of the initial roughness. After that, he's pretty insistent about getting into my pussy, but if I'm an active participant he's a lot less violent during it. Also, he seems to like hearing me talk, so I've used that a few times to get him off more efficiently."
Hal listened intently, like his wife was sharing a story of a problem she'd solved at work.
"What kinds of things do you say?" said Hal. He often heard her muffled voice coming from Gavin's room, but hadn't heard any of the words.
Carol's cheeks flushed.
"It's... it's a little embarrassing..." she said, shifting a little.
"More embarrassing than having to putz around the house while your son tries to nail your wife to his mattress with his cock?" asked Hal, not angry but not in the mood for Carol to suddenly put such a high value on discretion.
"Fine, fair enough," said Carol, taking a deep breath.
She told him that, in his hyper-virile state, Gavin seemed to like hearing her give him direction. Specifically, things like "fuck me harder" or "let me suck it" not only made him more pliable but also made him reach orgasm faster. She added, a hint of a blush coming to her face, that some aspect of their mother/son relationship also seemed to appeal to him.
"What do you mean?" asked Hal, curious.
"Well...," said Carol, taking a long pause, "I get a stronger reaction if I call myself 'Mommy' when I give him direction. Like 'Put it in Mommy's mouth' or 'Fuck Mommy harder'. It was pretty awkward for me at first, but it really seems to do the trick."
Just a few days earlier, that would've been an incredibly shocking thing for Hal to hear his wife say, but at this point it barely even made the list of crazy shit he'd been exposed to.
The only thing of note on day three was that around bedtime, well after Carol and Gavin had finished their hours-long session, when he had seemingly been back to normal, Gavin happened to catch a look of his mom in a nightgown. The sight apparently restarted his fugue state, and Carol had to give him one hell of a blowjob knock him back out of it. That was a frightening idea: that even after overcoming the initial period of hyper-virility, it could kick back in if he became sufficiently aroused.
Now it was day four, and Hal sat with his coffee thinking things through. All in all, it hadn't been the worst few days. Everything else aside, Gavin was delightful to be around and Hal was overjoyed that his depression was being treated so well. And though he'd never admit it, he had to acknowledge that there are worse things to look at than his sexy, busty MILF of a wife getting fucked like a pornstar by a stud with a big, fat hog. Sure, some of the shit Gavin pressed Carol to do made him queasy and the fire of jealousy never fully snuffed out of his chest. But there was something thrilling about having regular access to what amounted to a really hot, live sex show in his own home.
Carol seemed to be in good spirits as well, softly humming to herself as she poured herself some cereal. Apparently, a steady diet of mind-blowing orgasms did wonders for helping one get over the shame and taboo of fucking their own son.
Sitting at the table across from Hal, Gavin was also in a good mood though he was probably the only one in the family not thinking about sex.
"I was thinking we could all go for a bike ride later, what do you guys say?" asked Gavin hopefully, a boyish smile on his face.
"Oh honey, I don't know. I'm pretty worn out today," said Carol, stifling a yawn as she stretched out her back.
"Worn out?" asked Gavin, looking puzzled, "did you go to the gym yesterday?"
Gavin of course didn't remember that he'd spent the last three days twisting his mom around like a pretzel and pounding her like a hunk of raw meat.
Hal cleared his throat.
"Bike ride sounds great, pal," he said, giving his son a smile, "but don't forget we're moving your medication up to right after breakfast, so you might be sleeping til after lunch."
Gavin frowned a little. He'd expressed disappointment in losing so much of his days to the medication's "exhaustion"-inducing side-effect, but understood that it was ultimately helping him.
"Alright, I'll go take it now, hopefully it won't last too long this time," said Gavin cheerfully, finishing his toast and standing to take his plate to the sink. On his way out of the room, he stopped behind Carol, reaching around her shoulders to give her a quick hug. This was something he'd started just the last few days: being noticeably more affectionate (in a much more appropriate way) with his mother.
To the surprise of Hal and Carol, though, Gavin followed his hug with a quick smack of her ass. Much more of a playful pat than a sexual spank, but still not something he'd ever done before.
"Make sure those buns are ready for later!" said Gavin, giving an innocent smile and heading upstairs.
Hal was certain that Gavin meant he wanted Carol's sore buns to be ready for the bike ride later, but it was eerily prescient considering he was about to take his pills and give those buns a ride of his own.
"That was a little weird," said Hal once Gavin was out of earshot.
"Well considering how hard he's been smacking my ass the past three days, I'll take a nice pat now again," said Carol with a chuckle, her cheeks a little flushed, "I think the meds have just generally lowered his inhibitions. He knows a hug or a playful spank aren't anything sexual, so he doesn't even think twice about doing them anymore."
Hal considered his wife's theory, and agreed that it made some sense. Some wires in their son's brain were definitely a little tangled right now and a little innocent touching was hardly a concern in the face of everything else.
"I've got some work I want to do in the garden, I'm hoping I can fit it in before our session today," said Carol, glancing at her smartwatch.
"Session" is what they'd taken to calling her lengthy sexual encounters with Gavin. It seemed a more demure term than the more apt "fuckfests".
Hal glanced at the clock on his phone.
"Better hurry up," he said, raising a brow, "switching his meds to a morning schedule was a good idea, but if he's taking them now you've only got til about nine."
"I'll be quick. Man, it's hard to get things done when Gavin is filling up half my days!" she said, putting her bowl in the sink and heading for the back door.
"And a little more than half your holes," mumbled Hal to himself as she walked outside.
Hal puttered around the kitchen for a bit, doing some cleaning he'd fallen behind on. He was "working" from home today, but had little to accomplish and no drive to start on it. From the window over the kitchen sink, he watched Carol tending the garden near the side fence. She was wearing simple jeans and a t-shirt and she looked gorgeous. He heard a voice from the next yard over and he leaned a bit to see Brenda, their neighbor, approaching the fence to chat with Carol.
Brenda was a couple years older than Hal and Carol, firmly in her mid-40's. She was pleasant and a good neighbor, and Hal never minded seeing her jog by in her tight running outfit that showed off her skinny waist, toned ass, and medium-sized boobs.
But it was a flowy sundress that Brenda wore today, with a nice little pop of cleavage presented by its plunging neckline. It was a nice enough view that Hal just stood and admired it for a while: his buxom wife and the petite milf next door having a friendly conversation over the fence.
The low rumble of Gavin's footsteps coming down the stairs reminded Hal that, as he supposed Carol had done, he'd lost track of the time. It had been over twenty minutes since Gavin had gone up to take his pills.
"Shit..." said Hal as he listened to Gavin's footsteps rapidly approaching the kitchen.
When he entered, Gavin didn't seem to notice Hal at all, just strode quickly and purposefully to the backdoor, throwing it open and marching into the yard before Hal could protest.
"Shit!" Hal exclaimed.
He knew he should go after him, try to stop what was about to happen. He didn't for one embarrassingly selfish reason: he'd developed a noticeable tent in his pants while looking out the window that he didn't want his wife or Brenda to see. So he chose instead to simply watch the scene unfold the way he knew it would.
As Gavin started closing the distance to them, the two women turned and saw him coming. Brenda said something (probably "hi") with a friendly smile, but Carol's expression turned to dread. Gavin was beelining right for her, with a look in his eye she'd grown all too familiar with.
In a moment, Gavin was on her. Standing behind her, his body tight against his, he wrapped her in his arms. This was not the loving hug he'd given her just a short while ago, this was him reaching around to grab two big handfuls of her big tits through her shirt.
It was Brenda's turn to look horrified. Hal could only imagine what was going through her head watching her neighbor be openly and roughly groped by her own son. Hal saw her mutter something to his wife, probably questioning just what the hell was happening, and he saw Carol giving some kind of long response. He assumed she was telling Brenda about the medication Gavin was taking, as that was the only even semi-reasonable explanation for why her son was currently mauling her big tits and grinding his pelvis against her backside.
The longer Carol talked, the more Brenda's expression softened. Hal saw her asking questions here and there, and as Carol provided answers Brenda's expression turned from horrified to... curious.
As all this talking happened, Gavin was growing impatient. He'd gotten a hand up under his mom's shirt and was cupping one of her tits while his other hand fumbled with the button on her jeans. Carol wasn't stopping him, and more surprisingly, Brenda wasn't fleeing the scene. When he finally unbuttoned and unzipped her jeans, Gavin slid his hand down the front of his mom's panties and started rubbing her pussy.
Even as her son fingered her, Carol continued talking to Brenda, saying God knows what. Brenda was shifting about uncomfortably, but not like she wanted to leave. More like she really, really wanted to stay.
Eric stopped groping at Carol and used both hands to yank down her jeans and panties to her ankles. A little awkwardly, he pressed her forward, guiding her to the ground in a kneeling position, her elbows in the dirt of her garden bed. Only then did he remove his own pants and underwear, freeing the behemoth that lurked within them. Hal saw Brenda visibly gasp at the size of her young neighbor's cock, which jutted up from his lean body at a sharp angle, veiny and angry looking. She gasped again when, without any fanfare, he crouched and stuffed that huge thing into his mom's waiting pussy.
Gavin started fucking Carol with a pace and ferocity that Hal had become familiar with. Carol was taking it like a champ, her soft, round ass cushioning the blows from his pelvis as she bounced back to meet his thrusts. Brenda was the only one unaccustomed to the situation, and Hal watched as her hand idly rubbed at her neck, her eyes locked on the incestual scene playing out just over the picket fence.
Between grunts and grimaces, Carol was still talking. Hal could guess that, despite playing it fairly cool, Carol was freaking out about getting fucked in front of someone else. This was the woman who didn't even like to wear bikinis to the beach, and here she was, bare-assed, getting raw-dogged in the backyard.
Hal's hard-on was straining against his jeans. In the three days since Gavin had started the medication, Hal hadn't fucked his wife once. He hadn't even asked, doubting Carol's willingness and, frankly, not much wanting his son's sloppy seconds. He unzipped and pulled his hard dick out, wrapping it tightly in his palm and staring intently at the rippling of his wife's soft, round ass.
To Hal's surprise, Brenda too seemed to be getting into what she was witnessing. He watched, heart pounding with excitement, as her hand reached down to her pubic area, her fingers gliding in a tight circle over her covered pussy.
"Holy fuck..." muttered Hal, jerking his dick faster. His hot neighbor was getting off on this, same as he was.
The thought crossed his mind to rush outside, bend Brenda over the fence and fuck her brainless while they both watched Gavin do the same to Carol, but he couldn't quite bring himself to do it.
Meanwhile, Carol's face twisted as Gavin's humping was driving her to an orgasm. Brenda, one hand at her pussy and the other pinching a hard nipple over the dress, said something to Carol which Hal was pretty sure was "Are you going to cum?". Carol's hurried nod of a response just before the orgasm ripped through her seemed to confirm Hal's lip-read. Carol slapped a hand over her own mouth, somewhat stifling a moan that otherwise would have alerted the whole neighborhood. Her legs quaked and her arms turned to jelly. Gavin didn't let up for a moment, and only when the violent orgasm had passed did he quicken his pace, just for a few thrusts, before slamming his hips into his mom's ass and burying a fresh load in her sloppy cunt.
That was enough for Hal, who popped his own backed-up load into the kitchen sink as Carol rocked her body back and forth on Gavin's cock, milking as much cum from his balls as possible.
There was a long, awkward moment between the two women; Carol coming down from her incestuous orgasm and Debra sheepishly moving her hand away from her pussy, revealing a dark wet spot on the crotch of her dress. Gavin, however, could feel no such shame in his state. He delivered a sharp spank to his mom's pale ass, then slipped his still-hard cock out of her. As Gavin stood, Hal could see thick wad of cum drip from Carol's pussy onto the lawn, with more running down her smooth thighs.
On his feet, Gavin wasted no time pulling Carol to her knees in front of him and pushing his slimy cock into her mouth. Carol knew the drill and immediately got to work sucking the huge thing, his smooth, heavy balls swinging into her chin.
Debra stood on her side of the fence, looking unsure of what to do. Carol was now facing away from her with a mouth too full to talk. Gavin, though, seemed to have finally taken notice of the MILFy redhead on the other side of the fence. He was leering at her, like a lion ready to pounce on a gazelle. And fuck it.
Carols's hands gripped Gavin's thighs, his cock disappearing into her throat as her eyes watered and spit dribbled from the corners of her mouth. Gavin's hands were in her hair, pulling her down on his dick.
And then Gavin did something Hal didn't expect. He actually pulled his cock from Carol's mouth. Kicking off his shorts and pulling off his t-shirt, the muscular young man stood naked in front of his gasping, confused mom. When she saw his eyes though, she knew exactly what he was preparing to do.
"Gavin, no!" shouted Carol, trying to grab at him.
But it was too late. With a couple of quick steps and an easy vault over the fence, Gavin was now advancing on a wide-eyed Brenda.
Hal watched, bug-eyed as his son literally ripped the sundress of their sexy neighbor, revealing that underneath she wore only a pair of white cotton panties. Her boobs, though substantially smaller than Carol's, were beautifully shaped with soft, glossy nipples that made Hal's mouth water. She stood, stunned but seemingly not opposed, as Gavin's hands started to explore her every bump and crevice. Hal whipped out his phone, managing to take a few decent pics of his mostly nude neighbor being accosted by his son.
Carol struggled to her feet, waddling a bit as she tried to pull up her jeans and underwear. She was saying something, either trying to talk Gavin down or coax him back to this side of the fence, but the boy was well beyond listening. By the time Carol reached the gate, Gavin had picked up the petite milf and tossed her on his shoulder like Tarzan. Brenda didn't resist. When Carol caught up to them, they were most of the way to the backdoor of Brenda's house, then out of Hal's sight.
Hal blinked a few times, suddenly unsure if everything he'd just witnessed had been real. He stuffed his spent dick back into his pants and used the faucet to wash his load down the sink. He considered going over to Brenda's, a little worried about (and pretty interested in seeing) what Gavin might be doing to her. He chickened out of it, figuring that Carol would be able to handle the situation and that Brenda was clearly a willing participant. He looked at his phone, examining the photos of Brenda's tits he'd taken, reveling in the thought that he'd finally gotten a peek at them.
About five minutes later, Hal was on the couch, still looking at his pics, when Carol entered through the sliding door.
"Well, that was lucky," said Carol in a serious tone. Her hair was a bit more disheveled than it had been when Hal last saw her.
Assuming that Hal was unaware, Carol filled him in on what had gone down in the backyard. Hal played dumb and shocked, not wanting to admit that he'd seen the whole thing.
"...And then he dragged her into her house, tossed her on the couch and immediately was on top of her," said Carol, finishing her update.
"Is she... umm... ok?" asked Hal, wishing Carol had given more detail about Brenda getting plowed.
"She's fine, still a bit shocked I think, but I kept asking her if she wanted him to stop and she kept saying 'No!' in a pretty convincing way," said Carol, looking like someone who'd just seen a car collision.
"Well... I guess this at least means you get a break," offered Hal.
Carol grabbed her glass of water from the table and took a long drink.
"If only," said Carol, "even while Gavin was fucking Brenda his hands were all over my tits, and he kept pulling it out of her to jam into my mouth. I'm not sure Brenda can handle him alone. I just came back to tell you I'll be over there until he calms down, a few hours AT LEAST based on what I'm seeing."
Carol took another long sip, shaking her head a bit. Setting her glass down, she walked right back to the sliding door.
"God, I hope her husband doesn't come home early," she said as she closed the door behind her, leaving Hal alone with his stiff prick.
