Diogenes

I wasn’t supposed to be home early the day it all started.

Let me take a step back. My name is Dave. I live in a pretty typical suburb with my mother Sarah, older sister Kate, and our dog Diogenes (Dio for short). I’m in the final days of my senior year at the local high school, and Kate is a sophomore at a nearby college. Mom works from home; she’s a successful freelance marketing consultant. If I’m being honest, both my mother and sister are pretty attractive women. Petite, neither is more than 5’2″, but with decent figures, blonde hair, and greyish-blue eyes. It’s obvious they’re related. I’m 6’1″ and much darker than either of them, but somehow we all ended up with the same nose. Even though it’s just the three of us (Dad died a few years ago), we aren’t especially close. We tolerate each other pretty well, but honestly Dio is the member of the household to whom I’m closest. He’s a large dog, but a thoroughbred mutt.

I’m a boxer. Not professionally, it’s just a hobby I do in my free time. That isn’t something I can do through my school, so I have a coach down at a local gym. Every day after I’m finished with classes I walk down there and try to get in a few hours of training. At this point everyone in my family knows and expects that I’ll be home no earlier than 6pm, and since I’ve been able to keep my grades up and get into the same college as Kate it isn’t a problem.

On this particular day, however, my trainer texted me to let me know he had gotten food poisoning and wouldn’t be around. Ordinarily I still would have gone in for at least a little while, but there was just something in the air that made me say “fuck it”, so I headed straight home.

As soon as I stepped through the front door I could tell something was up. There was a weird energy in the house, and I could hear faint thumping noises coming from the living room. On pure instinct I decided not to announce myself, and instead crept toward the source of the noise. When I peered through the living room door, at first all I saw were several indistinct shapes moving rhythmically on the floor. It took a few moments for my brain to catch up and parse what I was witnessing.

My mother was on all fours on the floor, face down ass up as they say. Her blue sundress what hiked up around her waist, and a pair of pink-and-white striped panties were dangling off of her right leg. I couldn’t see anything, however, because Dio was behind her, paws around her waist, fucking her.

Mom was fucking the dog.

I was frozen in shock. I couldn’t see super well, but it was clear that Diogenes was pounding my mother’s cunt with his thick cock. Mom’s thighs glistened with what I took to be her own juices, and somewhere in the back of my mind I was impressed with the quantity of fluid Dio was able to make her produce. The distinctive tang of female arousal permeated the room. Obscene, wet noises were coming from where their bodies were joined, and Dio was panting happily. My mother, in turn, was moaning in what was clearly pleasure and vocally encouraging him to, and I’m quoting here, “ruin [her] bitch pussy with that big doggy-dick.”

It seemed like Dio was happy to oblige. The force of his thrusts was shaking my mother’s entire body, sending her face and tits sliding across the floor with every move. I was surprised to note that not only did Mom slide forward as Dio thrust into her sopping cunt, but then appeared to be dragged back with Dio’s pelvis. The movement struck me as extremely odd until it dawned on me that my mother was stuck on Dio’s knot; her pussy was attached to his cock, forcing her pelvis to follow both the forward and backward motion of the dog’s energetic copulation.

Mom moaned lewdly as Dio gave it to her with wild abandon. Her breasts had popped out of her dress, and I marveled at the way they looked dragging across the floor. As Dio pressed forward they were obscured under her body, but every time he pulled back and dragged mom along with him her firm, erect nipples were exposed to the air. Her long blonde hair covered Mom’s entire face, from her open panting mouth to her rolled back eyes. She was too busy using her hands to roughly twist her own nipples every time they were available to push the hair out of her face. I wondered for a moment why she didn’t prop herself up into a more dignified hands-and-knees position. Not only did Mom seemed disinclined to do so, but Dio periodically pressed his front paws between her shoulder blades. I knew Dio weighed more than she did, and my guess was that even if she tried to get onto all fours, the force of Dio pressing on her back would swiftly knock her down again. She was begging for it, but the dog was clearly in physical control of the situation. At this point my mother was just a sleeve for his cock, which based on her throaty moans and lusty panting suited her just fine.

I was so busy processing the scene, that I barely noticed I had immediately whipped out my phone and started taking pictures. Maybe I spent too much time on social media, but I just had to capture this moment. After getting a few good stills I switched to video and got what felt like an eternity of footage. Dio’s stamina was impressive. Not only was he lasting an impressive amount of time, but he was manhandling (doghandling?) Mom with ease. It wasn’t like rough sex between two human beings. I wasn’t a sexual prodigy by any stretch of the imagination, but I’d watched enough porn to know that human doms brought a certain level of intentionality to what they did. The application of force always had a goal; whether it was to satisfy the dom or the sub it was part of the sexual calculus. With Dio there was none of that. The way he kept her forced down the ground, the carelessness with which he slid her body across the floor, the purposeless ease with which he batted her with his paws all spoke to the thoughtlessness only an animal is capable of. More than any human partner might performatively claim, at that moment it was clear Dio saw my mother as nothing but a sex object to satisfy his own canine lusts. She was just a useful tool for getting his nut.

Suddenly, Dio tensed up. Mom followed him a moment later. The way she spasmodically kicked her left leg made it clear to me she was having an orgasm. She groaned from deep in her throat, making incoherent noises that almost had the characteristics of speech. Dio responded by swinging his hind leg over mom’s ass and bringing himself to stand facing away from her. They were still clearly attached by the knot. As Dio did this, panting happily, Mom’s incoherent groaning finally took shape into clearer human words.

“Oh fuck yes Dio, fill me up with you doggy-cum. I love milking your big thick knot with my stupid whore pussy. Fill me up, I want to feel you leaking out of me. Oh fuck yes Dio don’t stop cumming.”

Mom kept jerking periodically as orgasms ripped through her body and she kept begging the dog to give her as much cum as he could. She had her hands on her nipples the whole time, twisting and pulling them as she rode out what looked like three or four climaxes on Dio’s invading knot. Finally, Dio finished ejaculating. Mom lay panting on the ground as suddenly Diogenes slipped out of her with a wet squelching sound. It was clear he had taken mom’s request to absolutely fill her with canine semen seriously, as no sooner did his deflating red member slide out than what looked like a cupful of the dog’s watery spend splattered out of my mother and onto the hardwood floor. Once he slipped out of Mom’s pussy her unsupported legs sagged and her pelvis sank towards the floor. Heavy breathing filled the room. Slowly and shakily mom reached behind herself to rub her right hand over and into her swollen, used-up cunt. Taking a large helping of the dog’s ejaculate onto her fingers, she brought her hand up to her face and started feeding herself the foamy mixture of dog cum and her own juices.

As she licked the mess off of her fingers Mom groaned happily, but didn’t open her eyes. She made some grateful moaning noises, telling Dio how much she appreciated his gift. Once she was satisfied with her post-coital snack, Mom slowly started turning to look back at Dio, brushing her hair out of her face. Only then did the very real possibility that my mother might see me standing in the doorway kick in.

Ducking out of sight, I exited the house as quickly as I dared, followed the whole time by what I could only disbelievingly assume was the sound of mom sucking Diogenes’ cock clean from their combined juices. Once out the door I jogged down the street, unsure of where to go but convinced I needed to be away from the house. It was only once the panic receded in a local park a few minutes away that I realized the most shocking thing of all: I was hard as a rock.

I spent the next few hours wandering aimlessly, trying to distract myself from what I had seen.
