Scenario: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 The spark in his eyes had dimmed, and he had withdrawn into himself.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?" she said. Hal was caught off guard. This wasn't just some bizarre sex fantasy, his son was really fucking his wife. But it was clear they weren't going to be stopping until this ordeal was over. He decided to play along. "Uh, it was fine. Got a lot of emails to get through. Boring, really." "Uh-huh," said Carol, nodding her head, "th-that's good. What about-," she had to pause as Gavin moved one hand from her breast and shoved his thumb into her mouth and face-fucked her, "- what about, the, uh, Smith account? What happened with that?" Hal was trying to be cool with the situation, but Gavin was going to town on Carol's face hole, shoving his thumb in and out of her mouth, seemingly trying to make his mom gag. It was not an easy thing to ignore. "Um, well, Smith wants to meet on Thursday. I was going to ask you to come to lunch with us. It's at that place you like on Fifth. You should be able to come, right?" Carol nodded, and Gavin seemed to be satisfied enough with her oral skills that he removed his thumb from her mouth. "Mhmm, I'd like that," said Carol, wiping the spit from her lips, "if I can make it I will." Hal sighed. It was a nice distraction from the fact that his son was railing his wife six feet in front of him, but it wasn't like she could actually make it. She wasn't exactly in the best position to be making plans. Still, he supposed they were at least another half hour away from getting out of this mess. Best to just roll with it. "So, uh, Gavin," said Hal, finally acknowledging his son in the situation, "what did you learn in school today?" Carol and Hal both looked at Gavin, who, to both their surprise, looked back and answered, "We were learning about the French revolution in social studies today." His face still looked vacant, his expression almost bored, and he hadn't slowed down his pounding of Carol at all. Hal couldn't believe he'd even responded. He didn't look like he was paying any attention to what was happening around him. "What's the French revolution?" said Carol, also clearly surprised that Gavin was answering. "The, uh… the people revolted and overthrew the government and monarchy, I guess," said Gavin, a bit of the typical teenager coming through as he answered. "Was there anything interesting about it?" she said, clearly wanting to engage her son more, if he was open to it. "Yeah," said Gavin, pausing his thrusting momentarily, "the revolutionaries used to put the rich people and nobles on these tall platforms that lifted them up and then dropped them. It would take hours to die." Gavin's face was blank as he described the torture, and his pace had picked up to its original speed, his hips smacking into Carol's thighs as he fucked her hard. "Oh," Carol said, her mouth open and eyes wide with shock at Gavin's nonchalant description of the torture. "Yeah, it's like, the original 'drop' and that's where we get the word 'drop' from," said Gavin, continuing his onslaught of his mom's pussy. Hal didn't know how to react to what Gavin had said. He certainly didn't seem to be in any sort of mind to be learning anything, so he wondered if it was actually Gavin saying these things, or just his body repeating things he'd already learned. "Ugh, Gavin, not so hard!" said Carol as he jackhammered her cunt, "you're going to make me cum!" Hal's face twisted up with disgust at the thought. His wife wasn't supposed to enjoy this! "Mom, your pussy feels so good!" said Gavin as his mom squirmed beneath him, "it feels so nice and warm. I'm gonna cum in your pussy again!" Hal wasn't prepared for what happened next. Carol moaned as her body was wracked with orgasm, and Gavin grunted as he drove his cock deep inside her pussy and unloaded what looked like a full gallon of cum. As they rode out their orgasms together, Carol was shaking her head and mumbling, "no no no no no," as if she couldn't believe she'd just cum from her son's fucking. Gavin groaned and grunted, and finally, after what felt like an eternity to Hal, slumped over onto his mom's body. Hal breathed a sigh of relief. This was finally over. The nightmare could end. But, of course, that was too much to hope for. Gavin's head lifted from Carol's shoulder, and Hal felt a chill run down his spine as he saw that same empty, animalistic expression on his son's face. "I'm still hard," said Gavin, as he grabbed his mom by the waist and flipped her over, back into doggy, "I'm not done yet, mom." Hal could feel the blood rushing from his face. It couldn't be. It just couldn't be. Carol whimpered as Gavin slipped his cock back inside her. It was covered in his own cum and her pussy was making an absolutely lewd squelching sound every time Gavin moved his hips. "You can't be serious, Gavin!" said Hal, but his words fell on deaf ears. Literally, as Gavin seemed unable to hear anything. "You're not stopping, baby! Your cock is magic!" said Carol, though the words seemed to pain her to say, "but I need a break." Gavin just kept on thrusting, and Carol looked to Hal for help. "Can you please help me move to the chair? I need a break from being fucked on my stomach." Hal hesitated. The thought of touching his wife while she was in this situation was abhorrent. But he couldn't just leave her to take the full brunt of Gavin's animalistic fucking, either. With a heavy sigh, he stood and moved toward them. He wrapped his arms around Carol's waist and pulled her up. With his arms around her, he felt how sweaty she was, and her pussy made a wet, sucking sound as Gavin's cock left it. She stumbled a bit, and Hal held her up as she stepped out of her pants and kicked them off. "You ok?" said Hal, noticing her unsteadiness. "Yeah, it's just… fuck, I don't know if I can go again. He's fucking relentless!" Hal had a sudden realization, "Carol… when you said he came three times, you meant he came three times in you, right?" Carol turned her head, looking embarrassed, "Well… no… I made him cum in my mouth the second time… I didn't want him to fill up my womb with his cum… but… well…" Hal's eyes widened, "But what?" Carol swallowed, her throat clicking, "he wouldn't stop… after he came in my mouth, he just kept fucking my mouth until he got hard again… he came in my mouth again… and then he pulled me off and started fucking my pussy again… I think that might have been why my orgasm was so intense… I couldn't stop tasting his cum… ugh!" Hal felt like throwing up. This was so much worse than he could have imagined. His wife, his innocent little flower, swallowing their son's cum! He couldn't bear the thought. "Here, mom, get in the chair," said Gavin, grabbing Carol by the hips and walking her toward the lounge chair. He pushed her over the back of the chair so she was leaning on it, and pushed her legs apart. With one swift movement, he rammed his cock back into her, making her gasp and Hal grimace. "Ah, Gavin… give me a second…" said Carol, but her words were lost on her son, who was already back to pounding her pussy. Hal could see her cunt was red and swollen from the fucking it had taken, and there was a mixture of her juices and Gavin's cum running down her leg. He couldn't watch anymore, and looked away as Gavin started to grumble and grunt, signaling his impending orgasm. "Oh, fuck! Mom, I'm gonna cum! I'm gonna fill your pussy up again!" he shouted as he pounded her into the chair. Carol braced herself as Gavin rammed into her one last time and groaned, his cock pulsing as he filled her with more of his seed. Hal heard Gavin flop down onto the chair, clearly spent, and finally felt the nightmare was over. He looked at his wife, who was leaning over the chair, panting, her ass still in the air. It was red and sweaty, with cum still leaking out of her pussy. "You ok, honey?" said Hal as he moved toward her. "I… I… don't know… I've never been fucked like that before…" she said, still panting. "Did he hurt you?" said Hal, concern in his voice. "No… just a lot to take… my pussy feels so full…" she said, wincing slightly. Hal could see that. Her pussy was red and puffy, and he could see it clenching, trying to hold in all the cum Gavin had dumped in her. He felt a pang of guilt, knowing she'd had to go through this alone. "God… I feel so disgusting…" she said, wiping at the cum that was running down her legs. "You're not disgusting, honey… you were taking care of our son…" said Hal, trying to reassure her. "But I… I…" she said, looking up at Hal, tears in her eyes, "I came… from our son's cock… I'm so sorry… I didn't mean to!" Hal was taken aback. He hadn't considered how his wife might be feeling about everything. He'd been so caught up in his own disgust and anger, he hadn't thought about how she might have felt, being used like this by her own son. "It's ok, honey… it's not your fault… I know you didn't want this… you were just taking care of him…" said Hal, putting his hand on her shoulder. "But I came… from my son's cock… and I liked it…" she said, tears streaming down her face. Hal was shocked. She'd liked it? This whole time, he'd thought she'd been enduring the whole thing, but to find out she'd actually enjoyed it! He didn't know how he felt about that. Part of him was still disgusted, but another part of him was… intrigued? He shook the thought from his head. Now wasn't the time. "Honey, don't be sorry… it's ok… really…" said Hal, as he rubbed his wife's shoulder, "we'll figure this out… we'll get through this… together… ok?" Carol nodded, sniffling, as Hal continued to rub her shoulders. She looked up at him, her eyes red and puffy from crying. "Thank you, Hal… I don't know what I'd do without you…" she said, giving him a weak smile. Hal smiled back, and leaned in to kiss her forehead. "Let's get you upstairs and into the bath. We can figure out what to do about this tomorrow," he said, as he helped her up. She nodded, still a bit shaky on her feet, as Hal led her out of the living room. He glanced back at Gavin, still passed out in the chair, his flaccid cock resting on the cushion. Hal shook his head, and closed the door behind them. This whole situation was fucked up, and he didn't know how they were going to handle it, but for now, he just wanted to take care of his wife.
