My husband and I decided on a whim that we would love to have a child of our own before my birthing clock stopped ticking. My husband’s vasectomy reversal failed, with the psychological ball in motion, we decided to go about things a little differently. I knew I was getting close to ovulating, and after some discussion between my husband and me, we decided to take up Mistress Alicia’s offer to use her four pedigree slaves. We thought that at least this way, it wouldn’t be too obvious who the father was, hopefully diluting the possible emotional impact that could arise later.

A slave swap was organised between Olivia, the only female slave of Mistress Alicia and me. The swap started one Friday afternoon and lasted all weekend. After getting through the first night of pleasuring Mistress Alicia, various BDSM sessions and getting used to her four male slaves being around, Saturday morning was chosen to be the breeding day.

The four male slaves were all fit and intelligent, except that only three were fertile. Mistress Alicia had kept them locked in chastity devices and forbidden to cum for several weeks. She told me about their backgrounds yesterday afternoon when I first arrived. One was a surgeon, another a barrister, and the third a chief executive officer from a large corporation. This is what Mistress Allicia referred to when she mentioned pedigree slaves. The fourth slave was Boi, but I already knew he was sterile from having a vasectomy.

Breeding Day Begins

It was sometime Saturday morning when Mistress walked into the room and said, “Okay, it’s time. Let’s get this bitch ready, she’s on heat and ready to breed.” I was too exhausted to really take in what she’d said. It had been a strenuous and sleepless night. I lay in the timber bondage frame like a limp rag doll. Mistress and Boi began releasing me from the many Velcro straps holding my naked body firmly in place.

Even with all the straps undone, I just stayed in place, lying over the top of the frame, feeling too exhausted to get up. I didn’t move until Boi picked me up and carried me in his big arms back to my bedroom. He laid me down on my bed amongst a pile of black leather items and what looked like some sort of harness. Boi began slipping my arms into long black leather sleeves. The sleeves contained several buckles halfway down the length, with what looked like dog-paw-shaped mittens on the end. Each sleeve covered the entire arm, just short of the armpit, with an internal pad for protection at the elbow.

When my hands were inside the mittens, I had to keep my fingers clenched as a fist. Boi bent my arms at the elbow and buckled up the straps. The straps kept my elbows bent at a fixed angle, preventing me from straightening or bending them completely. He picked up a pair of similar-looking black leather sleeves from the bed, but these were larger. Each sleeve had similar buckles and an internal padded knee cup located halfway down its length. At the ends of each leg sleeve were larger slippers resembling dog paws. The underside of each paw featured an adorable pink print.

Boi began slipping on black leather leg sleeves over each leg. They were the perfect size, and each foot fit snugly into the large, paw-like slipper at the end. Boi helped me get off the bed and onto my feet. He pulled and tugged at each leg sleeve, ensuring they were pulled up as high as possible. I wriggled my toes within the slipper paws, confirming my feet were as far in as they could go. The leg sleeves covered my entire legs, nearly up to the groin.

Boi then buckled a wide, heavy-duty waist strap around my waist, which he had taken from the bed. The big strap buckle was at the front of my body, and smaller leather straps dangled down each side of my hips. He buckled the smaller straps onto loops attached to the thick band at the top of the leg sleeves. I thought this was to stop the leg sleeves from slipping down my thighs. Boi bent down and made sure each knee cup was in the correct position. He took hold of my arm and said, “Get down on your hands and knees”.

“Yes, Sir,” I said, lowering myself with Boi's assistance. Once down, he adjusted my position, ensuring my knees were spread wide apart and fitted into the padded cups. When the positions of my arms and knees were correct, he began securing the various Velcro and leather straps above and below my knees. Once tightened, my knees were firmly locked into the padded cups, which not only protected my knees, making them exceptionally comfortable, but also prevented me from straightening my legs. Boi tested his strapping by having me try to straighten each leg. I could only bend my knee joint, but couldn’t straighten my leg any more than about ninety degrees. Boi then connected the corresponding knee and elbow on the same side using a stainless-steel chain approximately 400mm in length.

Just then, Mistress walked into the room holding several things in her arms. “Oh my! You have done well getting this puppy bitch ready,” she said excitedly.

“Thank you, Mistress”, Boi replied. Boi continued getting me ready. He adjusted the two straps that passed down the outside of each hip from the waistband to the leg sleeve. He pulled each strap up tight so that the curve of my hips prevented me from bringing my knees closer together. It was more comfortable to keep my knees wider apart because, if I tried bringing them closer, something sharp on each strap dug into the side of my hips and caused pain.

After placing everything on the bed, Mistress picked up the wide black leather studded collar off the bed and held it to my face. The collar was at least 50mm wide with four rows of short chrome studs around the circumference. Not only that, attached by a slip ring, it also had a hefty pink coloured tag shaped like a bone with “LAURA” inscribed in big black letters. “You have got to love this personalised collar, Laura. It suits you. Wait, by the time Boi and I are finished, you will be the cutest-looking puppy bitch on the planet,” Mistress said.

Next, she picked up a black leather mask shaped like a dog’s nose and muzzle, which included upright ears and an internal ball gag. She held it in front of my face and said, “Don’t you think this is cute? It’s going to go well with your black hair. However, I am going to remove the internal ball gag. But if I hear anything from you more than a woof or a whimper, this gag will go back in for the rest of the weekend. Do you understand!”

Thinking quickly, I replied with, “Woof Woof!”

“Oh. This little puppy bitch is very smart, Boi. Hopefully not too smart for her own good,” Mistress smiled.

Mistress buckled the studded collar around my neck, with the pink tag dangling down at the front. She made sure it was on tight—tight enough not to choke me when I maintained my current posture, but enough to remind me that it was constantly there. The presence of the collar quickly reminded me of my submission. Mistress then placed the leather muzzle over my chin and nose and buckled up the main strap behind my head. Another strap held the two ears in place, which passed over the top of my head and linked with the main strap around my head. The muzzle, shaped like that of a large dog, completely covered my chin, mouth, and nose. Small holes in the front allowed me to breathe through my nose.  

Mistress then picked up a black solid butt plug off the bed. It was made from black silicone and about thirty-five to forty millimetres in diameter. It also had an upcurved tail made from hard silicone, measuring about one hundred and twenty-five millimetres in length. She placed the butt plug inside her mouth and made sure it was covered with plenty of her spit. She then pushed the bulbous end of the plug into my sphincter and began wriggling it. At first, it felt like my sphincter muscles were fighting against it. But eventually, they relaxed enough to spread open, taking the plug inside. As the muscles stretched open, I let out a loud moan, almost a scream through the muzzle.

“What did I just tell you about making noises?” she boomed. I quickly made whimpering noises but couldn’t stop the loud panting as the pain in my sphincter muscles slowly dissipated. “That’s a good little doggy bitch,” she said. Once the butt plug was in through my sphincter, the muscles closed tightly around the stem of the plug as if they were taking tight possession of it.

She took a length of chain and attached one end to the back of my collar, and the other end to the butt plug somehow. The chain was tight, and the moment I bent my head down, it pulled the butt plug, causing some pain. It forced me to keep my head up and alert. Mistress went and got a mirror, held it up to me, and said, “Aww, who’s the cutest puppy now?” I looked like a humanised dog. The collar and arm sleeves kept my posture straight. The stiff, black, up-curled tail attached to the butt plug made it look like I was offering myself to anyone who wanted. I leant forward, placing my elbows on the floor to give my arms a rest. My face was close to the floor leaving my arse and vulva up high and fully accessible. Doggy style, I thought to myself.

Mistress ran her fingers over my bald pussy as if reminding me how accessible I was. I was now horny again; the preparation, as well as the anxiety of not knowing exactly what was about to happen, was making me aroused. I thought I looked incredibly sexy in the mirror, but at the same time, I felt incredibly vulnerable. She produced a small jar with bright red contents and showed it to me. “You see this? This is a lubricant coloured with food dye. I am going to rub this over your vulva, so it stains your skin, giving the impression you are on heat.”

Mistress removed the jar’s lid with a gloved hand and began massaging the red-coloured stuff over my vulva. I was so aroused by now; I started to instinctively push back against her hand as she massaged and poked the stuff into my vagina. “I’m beginning to think that you’re on heat, especially by the puffiness of your Vulva and how red the entrance of your vagina is from arousal. You’re a horny little slut, my dear little bitch dog”, Mistress said affectionately. She kept rubbing the area with whatever was in the red concoction. Eventually, she stopped and wiped away the excess. “What do you think, Boi?” Mistress asked.

“I think it’s perfect, Mistress. The red colour accentuates her swollen and puffed-up pussy, making it look much more pronounced”, Boi replied after giving me a close examination from behind.

“Okay, I think it’s time to get this little bitch bred by the three big dogs. I know they have lots and lots of hot sperm saved up, just waiting to fill your womb. Come along, little dog,” Mistress said excitedly. Mistress Alicia attached a leash to my collar and began slowly walking me out of the bedroom. I fumbled at first, but I quickly learned that if I moved the knee and arm on the same side in unison, I could move in a clunky way. With each movement I took, I felt the chain pull the butt plug, and anytime my knees got too close together, something sharp pricked me on the sides of the hips, reminding me they needed to be wider apart.

Slowly, Mistress and I made our way through the house. It was the first time I felt like a dog; the mask with muzzle and ears made me look like one. I felt incredibly vulnerable with my vulva accessible from behind and somewhat helpless because of what I was wearing. The way my arse swayed back and forth as I clumsily progressed through the house on my knees and elbows. I was led into a sparse room I had never been in before. In the centre of the room was a large steel cage measuring about two metres square and approximately two metres tall. It was constructed from heavy steel vertical bars, with three horizontal bars connecting the others. There was a small round opening on one side of the cage. This opening had a door arrangement which I presume was meant to hold a person’s head in position. There was an upright post at this opening that featured several attachment points. The main access door of the cage was on the side opposite the smaller opening.

The room was mirrored on three walls up to a height of about two metres. It was the first thing I noticed when I entered, as I couldn’t help but see myself, the humanised dog, being led into the room. The fourth wall featured a huge window that looked out onto the lush rear garden. The three pedigree slaves were already in the room, each of them attached by chains from their studded collars to the floor. They were naked except for wearing a black leather dog mask with a muzzle and ears similar to mine. Their hands were secured into dog paws like mittens, which prevented them from using their fingers.

All three men had been finally released from the chastity devices I saw them wearing last night. Instead, they were now wearing a stainless-steel cock ring which circled their cock and balls. These rings made their erect cocks larger and harder than usual. They each knelt in a way that made them look like dogs who were alert and eager, waiting for instructions from their owners.

As Mistress Alicia led me into the room, the eyes of the chained-up men locked onto me. “Gentlemen, here’s Laura. She’s your new breeding bitch who’s ready to have some puppies of her own. I want your hot sperm filling her uterus and fertilising that egg. She’s in season and ready to breed. I’m sure you won't have any trouble doing this,” the Mistress said. The moment Mistress finished speaking, the three men excitedly jumped up and down and barked or howled like dogs. They were genuinely getting into the role of being dogs, even to the point of pulling against the chain that attached each one of them to the wall. “Oh, good boys. You’re all so excited, aren't we? You're excited to play with your new girlfriend. But not without me letting every one of you get a closer look,” Mistress said, smiling. This brought another wave of howling and barking as they desperately pulled against their chains and excitedly bounced around like real dogs.

“Sit and be quiet!” Mistress Alicia yelled. The three men all went quiet and quickly sat, kneeling upright with their arms straight, waiting in anticipation. Mistress tugged on my chain and instructed, ”Turn around, little bitch, show the big dogs how aroused your puppy pussy is.” I turned around slowly so my bare arse and vulva faced the men. I leaned down so I could rest on my elbows, making sure my knees were wide apart. I suddenly became much more aroused than before. I could feel the wetness from the red lubricant combined with my vaginal fluids accumulating around my labia. “Oh, good girl. Look at this beautiful bitch. Look how aroused and excited she is waiting for you dog cocks,” Mistress told the men, smacking my arse cheeks several times. The three men started barking and howling like real dogs again. “BEHAVE!” Mistress yelled at them. “If you are all good dogs, I’ll let you have a closer look,” she went on to say. Mistress tugged at my leash again, wanting me to move my arse and pussy closer to each man in the row.

Mistress guided me close enough to each slave dog so my arse and vulva were in sniffing distance. I started with the man closest, and after about thirty seconds or so, Mistress moved me onto the next, and then the last one. For some reason, this aroused me to an entirely new level. One of them reacted much more enthusiastically than the other two. He happened to be the man with the biggest cock. By the time I finished, I couldn’t help noticing that all three men had hard cocks. The stainless-steel cock rings, which were squeezing their balls and cocks tightly together, enhancing the physical effect. Their cocks were all rock-hard.

Mistress Alicia opened the main access door of the cage and led me inside to the opposite side. She raised the small sliding trap door and gestured for me to place my head through the opening. The moment my head was through, she lowered the small, barred door, trapping my head like a pillory. My head was now outside the cage, my body with its bald aroused vagina inside the cage, waiting to be impregnated. I was resting on my elbows and kneeling with my knees wide apart. My arse and vulva up high, totally accessible to whoever was about to fill me with hot cum. I felt incredibly helpless, with my head trapped through the side of the cage and not being able to see what was going on behind me.  

A throne-type chair was positioned in front of my head and sat between the cage and the window. I assumed this was for Mistress to watch the action. Like found in so many of the rooms around this house, a CCTV camera was mounted on top of the cage to film what happened inside. Mistress Alicia closed and bolted the cage door and walked around the room carrying two devices. One was a long electric prod used for delivering electric shocks to whoever needed it, and the other looked like some vibrator, except with a doughnut-shaped loop on the end. “Okay, boy and girl dogs. I want you on your best behaviour; if not, then this is what’s going to happen to you,” she warned, poking the prod in through the cage tapping the end on my arse cheek close to my pussy. It made an instant zapping noise; the intense electric shock made my entire body flinch uncontrollably. I yelled and whimpered loudly through the muzzle as the pain took a while to subside.

Mistress then picked out the man in the middle of the three and touched the prod on the pubic region above his cock. The zap seemed even louder, making him flinch violently, only to be stopped by the chain attached to the floor. “Aww, your poor cock got scared and has suddenly become flaccid again. Pathetic! Here, let me fix that for you,” she told him.

Mistress Alicia turned on the other wand with the ring at the end, making it come to life with a loud buzzing noise. She placed the vibrating doughnut ring over the same guy’s cock, and in no time at all, it came back to life again, just as hard as it was before. It was her version of a fluffing tool to keep the men’s cocks hard in the event they lose the erection. As the vibrator buzzed away, the guy began to whimper. He must have been getting close to ejaculating; he was on the edge in no time at all. Mistress started laughing and said, “I’m warning you not to cum; I need you to fill that bitch in that cage.” Pointing at the cage when she said it. The moment the guy started howling loudly like a dog, Mistress quickly turned off the vibrator.

Mistress went behind the big chair and picked up a five-metre length of black rope with a snap clip on one end. She threw the rope, clip and all, over the top of the cage and then entered the cage to thread the rope through the overhead bars, ensuring the clip dangled directly above my arse. The other end of the rope was hanging down over the front side of the cage, close to my head but within reach of her chair. “Okay, I think it’s time to get this show on the road before this bitch stops ovulating,” she said excitedly.

Breeding time

 Mistress unclipped one of the men from the floor and dragged him harshly into the cage. He whimpered as Mistress roughly handled him into position behind me. He rested his mitten-covered fists on my back, and his thighs pressed against the backs of my legs. His hard cock was pointing downwards between my legs with its stiff shaft resting against my aroused vulva. Mistress Alicia clipped the rope hanging down from the top of the cage onto his collar. “Stay! Be a good boy,” she said. “Not yet,” she continued.

I was horny as hell, knowing that someone with a hard cock was about to fuck me. I started subconsciously wriggling my hips as if inviting him inside me. Mistress Alicia sat down on her chair and pulled the rope tight. I heard the guy behind me let out a slight choking noise accompanied by a yelp. “Good boy, you can fuck the bitch, but slowly”, she instructed him. He pulled back slightly, moving his body around to get the head of his cock at the entrance of my pussy. He was nearly on target; I moved slightly to help him. I felt the hard bulbous head, covered with precum, pressing between my labia; a moment later, I gasped loudly as it entered my vagina.

I wasn’t as wet as I first thought, most probably due to the amount of sex I’d had in the previous days. His precum wasn’t enough, and because of his dog muzzle and the mittens covering his hands, he couldn’t even use his saliva to help with the situation. “What’s wrong with you, dog? Can’t you get your cock in her tight little hole?” Mistress boomed. He began whimpering for fear of being zapped by the wand. With lots of little thrusting movements, his cock slowly worked its way deeper and deeper as his precum started providing lubrication. Eventually, it was enough for him to start slowly thrusting deeper and harder.

I love being fucked slowly; the slower, the better. It allows me to feel every lump, bump or engorged vein along the shaft as the cock passes through the entrance of my vagina. Every time his cock was buried deep to the hilt, I pushed backwards slightly as if trying to get it deeper inside me. Now and again, Mistress Alicia tugged on the rope attached to his collar, making him stop thrusting and gag a little, only to finish off with some dog-like whimpering when she released the tension. The more he fucked me, the more cum he leaked and the slipperier my vagina became. At one point, when his cock slowly entered me, I orgasmed, making my entire body quiver and shake as it flooded through my body. This orgasm made my vaginal muscles clamp his shaft tightly, trying to stop him from withdrawing. 

He must’ve been getting close to ejaculation. When Mistress tugged the rope taut, he hooked his mitten-covered paws around my hips and pulled me tightly into him.  He began ejaculating, filling my hole deep with copious amounts of hot ejaculate. The feeling of him cumming triggered another orgasm in me.“Don’t you dare pull out, dog? I want you to leave your cock deep inside her; I want you to knot her, to make sure that cum of yours soaks into her uterus!” she instructed.

The high position of my pussy and the downward angle of my body make it the perfect position to be filled with cum and have it soak deep inside me. “Laura, you little dog bitch, if I see you push any cum out from your hole on purpose, I will zap your clitoris with this wand until it looks like a burnt crisp!” she shouted. I whimpered a little to let her know that I heard her. “Good girl,” she said, reaching down and stroking my head gently with her hand. It was lovely being stroked by her; it gave the impression that she was affectionate, even though she can sometimes seem harsh and demanding.

Mistress Alicia pulled the rope taut, stopping the guy from thrusting. His cock was still hard and buried inside me, soaking in his cum. He had ejaculated quite a lot; he must’ve been saving it up for weeks. I was beginning to get the impression that this was the case with the rest of the men as well. Apart from Boi, who had already filled my stomach, the others had been kept in chastity for quite a while. I knew Boi was sterile and only shot blanks. Mistress mentioned it the last time they visited our place. However, based on what Mistress said earlier, the other three men were fertile and eager to breed. I was the breeding bitch, the one with that lonely egg in her uterus, with the sperm from three men competing against each other for the task of fertilisation.

I could feel this guy's cock begin to get flaccid. I tried wriggling my hips into him a little. “Times up, dog, get off that bitch now!” Mistress boomed. He slowly withdrew his cock making some of his hot cum dribble out from my vagina and down over my clitoris. Mistress Alicia entered the cage and unclipped the rope from his collar. She pulled him forcefully out of the cage and back to the floor, where he was initially tethered. Despite her petite stature, she displayed remarkable strength in handling a man larger than herself.  

Next Doggy

Mistress Alicia moved over to the next guy along, whose cock was larger than the first. I’m guessing she decided to start with the smallest cock of the three and finish with the big one. The smallest cock was still plenty big enough, the size difference between each of them wasn’t that significant, but it was still something. The moment she unclipped the chain of the second guy from the floor, she yanked his collar incredibly hard, so hard that he fell over on his side. “Get up now: you are fucking pathetic creature!” she bellowed. “Get the fuck up, NOW!”. The guy quickly got back upright to a crouching position, almost like a dog. She grabbed him by his collar, dragged him into the cage, and positioned him close behind me. The rope hanging down from the top of the cage was clipped onto the loop of his collar. “Aww, I’m sorry, puppy dog, looks like I scared your cock and it's gone into hiding,” she said, amusingly.

I felt him kneeling behind me; his limp cock was resting against my slit. I even tried wriggling my hips, hoping it would arouse him. I think Mistress Alicia’s actions shocked him, or it was a simple case of stage fright. If I could have, I would either slowly wank or suck him hard. Sadly, I wasn’t in any situation to make a difference. Mistress retrieved her magic vibrating wand from beside her chair and came back inside the cage. She pulled the guy back away from me and placed the doughnut end over the head of his cock. The moment she turned it on, intense vibrations started vibrating hid cock. He whimpered briefly, from shock or from pleasure. “There you go, Dog, that should help things—nothing like a good old vibrator to do the trick. Look, look at that; it’s getting bigger by the second,” she said. In no time at all, his cock was rock hard. I heard her leave the cage, closing the door behind her. The shaft of this guy’s cock rested up through the crack of my arse. I began wriggling my hips slightly, but he grabbed hold of my hips and held me tight.

“Okay, Dog, you may now seed the bitch. Nice and slow. Fill that love tunnel with your cock and pump that sperm into her uterus,” she instructed. He gave a “Woof, Woof” noise. He pulled his body back allowing his hard cock to slide downwards over my sphincter, until its head pressed at the opening of my vagina. After a bit of jiggling, its hard-rounded head pushed its way into my vagina. I moaned out loud as it spread open the entrance and slowly squelched its way deep into me. Being filled with ejaculate already provided ample lubrication for his long cock. Suddenly, Mistress reached through the cage bars over the top of me and zapped me on the top of the arse cheeks. My body flinched as I wasn’t expecting that. “Laura, my darling little bitch, what did I say about making noises earlier? A bitch does not moan; they only whimper, bark, growl, and whine. Choose the appropriate one or be prepared to have that clit of yours zapped,” Mistress warned. I began whimpering loud enough to please her.

In fact, when he slowly pushed his long cock into me, I couldn’t help but whimper when I felt every blood-engorged vein along its shaft passing slowly through the entrance of my vagina. I yelped loudly as he thrust his cock into me and whimpered softly as he withdrew it even slower. He took control, holding my hips tightly, so he could regulate the thrusting speed and stop me from pushing back into him. He had expert control of his cock and my body. As he withdrew his cock, the trapped cum already filling my body made a loud squelching sound. When he slowly pushed his cock back in, it felt like a hydraulic ram forcing every drop of cum into my uterus.

Fuck I was horny, it didn’t take long before I orgasmed. He must’ve known it was coming; he stopped thrusting and held me tight the moment it arrived. When the muscles of my pelvic and abdominal region finally stopped contracting, he recommenced fucking me slowly again. Mistress Alicia was stroking my hair, but all I could think about was being fucked. With my head locked through the side of the cage, if I wanted to stretch my legs out behind and lay flat, I couldn’t because the elbow cuffs and knee cuffs were connected forcing me to keep my arse sticking up in the air. This was just how Mistress wanted me, arse and cunt up high on the maximum angle so the men could fill it with the most amount of cum.

I noticed the guy’s thrusting rhythm changed slightly. I wondered if he was getting close to cumming. No man can keep up this slow and controlled fucking motion without changing the rhythm, especially when they’re about to ejaculate. Just the thought of this alone made me more aroused than ever. As a well-trained submissive, I’d been taught to orgasm at the same time a man cums, didn’t matter if was in my mouth or any other hole. It took time to learn and have it embedded into my psyche, but now it happens automatically.

The guy began grunting, not a sound a dog would make. I was close to orgasm as well when suddenly Mistress pushed the wand in through the side of the cage and zapped the poor guy on his arse cheek. The zapping sound of the solid electrical spark biting into his flesh made his entire body flinch. The feeling of his cock shaking inside me instantly triggered my orgasm. The orgasm was intense, and it had been building up for quite a while. It lasted much longer than usual, making body quiver and shake and every muscle around my vagina tensed tightly, clamping the guy's cock inside me. He suddenly growled loudly like a dog and filled my pussy with several big loads of ejaculation. He kept thrusting his cock deep inside me, each thrust engulfing my cervix with cum. He panted heavily, his thrusting stopped with his cock buried deep inside me.

“Don’t pull out!” roared Mistress. “I want your cock and cum to keep soaking in this puppy bitch for a while longer.” For some reason, those words triggered another minor orgasm inside me, one that was enough to shake my hips. Fuck I was horny; I tried thrusting back and forth on his cock. I wanted more; I wanted to be fucked, not just filled with cum. Mistress reached in through the cage with the wand, zapping me on the arse cheek again. It shocked me as I wasn’t expecting it. I pulled away, which made the guy’s partially flaccid cock slide out of me, followed by a small load of cum. “Do worry, my dear, you must be so horny. I can tell you’re wanting to be fucked long and hard. Later tonight, when these horny dogs have produced more cum, you’ll get your wish”, Mistress said. She opened the cage, grabbed hold of this guy by his collar, and pulled him out. She clipped the chain attached to the floor onto his collar and said, “STAY!”

Man Dog, Big Dog – Sometimes the best is last

Mistress Alicia went to the third and last guy in the line, who happened to have the fattest and longest cock of the three. It was nice that she was saving the best for last. I noticed precum dripping from the end of his cock. A thin string was stretching its way down towards the floor, creating a small wet patch where he was kneeling and waiting. The moment the Mistress Alicia unclipped the chain from his collar, he howled loudly like a wolf expressing his excitement, making her happy, “Oh, Big dog, you are excited, aren’t you? I bet you can’t wait to fill that little cunt in that cage. Give that bitch every drop you can, I say”. The moment she mentioned that, he became even more excited. She led him into the cage and told him sternly, “Sit! Stay!” He obediently sat like a dog over to one side of the cage. I had no idea what she intended to do.

“Laura darling, I’m going to reposition you in the centre of the cage, so you are lying on your back. It will give your knees a rest and allow that cum inside you to soak into where it's supposed to go,” she informed me. Mistress pulled the rigid dog tail butt of my sphincter. To remove it, she wriggled it from side to side whilst pulling. It felt like my sphincter muscles were fighting against her, trying to stop her. The moment the butt plug was removed, my sphincter snapped shut, I squealed loudly, even though I wanted it to be like a dog’s yelp.

Mistress Alicia unlocked the trapdoor on the side of the cage and removed my head from the opening, so my entire body was now inside the cage. She unclipped the chains attached to my elbows and knees so I could move my legs. “Without leaking any of that precious cum, I want you to roll over on your back and raise your legs into the air”, she commanded. I rolled over onto my back, and with my hands behind my knees, I pulled them back towards my head as much as I could. The moment I was on my back, I felt immediate relief in my knees. Kneeling for so long in that position had become quite uncomfortable.

Mistress Alicia went and came back with a spreader bar. This bar had wrist and ankle cuffs attached. A metal loop, used for securing rope or chain, was mounted between the two wrist cuffs at the centre of the metal bar. She began removing the leg sleeves and knee pads I had been wearing and then used her body to support my legs, keeping them high. My ankles were locked into the larger cuffs located at either end of the spreader bar. The rope dangling down from the top of the cage was clipped to the metal loop in the centre of the bar. This rope was tied off to the cage temporarily to keep my ankles high.

Mistress Alicia then removed the elbow cuffs, finally giving me a chance to straighten my arms. The overhead rope was released enough to allow the spreader to be lowered until my arms were within reach of the two wrist cuffs on the spreader bar. I bent the upper half of my body upwards to make it easier for Mistress to lock my wrists into the wrist cuffs. “Smile at the camera; shame you won’t be able to wave,” Mistress said, pointing upwards at the CCTV camera mounted above. I was too caught up in what she was doing to me to worry about who was watching me through that camera.

With both my ankles and wrists locked into the cuffs attached to the spreader bar, she adjusted the overhead rope so my body was back flat on the floor. She repositioned the rope and tied it off so my arse was raised off the cage floor which forced my knees apart. This also meant that my arsehole and pussy were totally accessible for anyone to do whatever they wanted. I may have been made up to look like a dog with the dog mask, ears and paws, but right now I felt more like a tortoise lying upside down, arms and legs in the air, helpless and about to be totally fucked. When Mistress was finally satisfied with her bondage work, she left the cage and locked the door behind her. I was now alone in the cage with the man made up as a dog, she named “Big Dog.”

I lifted my head and looked at him; he knelt with his arms straight, staring at me, not shifting his gaze. His hard cock pulsated and twitching between his legs, and he was ready to pounce at a moment's notice. For some reason, this felt so intimidating. He let out a loud howl, and Mistress shouted, “STAY! Don’t you move, or you’ll be punished! I want you to wait a few more minutes whilst all that cum inside Laura’s cunt has a chance to trickle back deeper into her love canal,” she told him. “Don’t worry, Big Dog, you’ll get your chance. I want you to fill that tight pussy of hers with loads and loads of sperm,” she said enthusiastically.

Mistress Alicia left the room for a moment. I glanced up at Big Dog, who still had his gaze fixed on me. His steely blue eyes through the leather dog mask seem to pierce straight through me. Not only was he the most well-endowed out of all the slaves that Mistress had in her house, but he also had the most athletic body. His arms and legs were ripped with muscles. His abdomen was ripped with muscles like a twelve-pack. His body was so fucking sexy, and I was helpless in restraints with no way of touching it. His poise and intense stare made me a bit nervous. He was strong, and I worried he might be too aggressive. The leather mask, which made him look like a dog, concealed much of his face, making it difficult for me to judge his character or demeanour. As time went on, I began to relax, and I knew in the back of my mind that Mistress would punish him if he did anything wrong.

Since having my ankles and wrists locked together onto the same spreader bar and raised into the air, the vulnerability and anxiety were making me more and more aroused the longer we waited. My clitoris was swollen and throbbing, aching to get this muscular man on top of me and his cock buried as deep as it could go. I felt sure he was thinking the same thing. I looked up at him and thrust my hips up and down. I did it to tease him, showing him that I wanted his cock inside me. He knew I was turned on; he could tell I was desperate to fucked hard and deep. The more I thrust my vagina up and down whilst looking at him, the more his erect cock dribbled precum onto the floor. I hate seeing waste like that, wishing I could suck his cock and swallow every drop of precum I could get from him.

I was becoming more and more desperate to be fucked. I began whimpering loudly like a whining puppy bitch, hoping that Mistress would respond and let this guy at me. Not only was I aroused from seeing his beautiful body, but also from knowing what was coming my way. My helpless situation added further to the arousal, making everything so more intense. The guy began letting out long, loud howls like a wolf. I started whimpering as loudly as I could, just like a needy puppy. Moments later, which was beginning to feel like an eternity, Mistress walked back into the room. She could sense the sexual energy that was building inside this cage between the two of us. “For fuck’s sake, you two!” she exclaimed and sighed loudly.

“Okay, Big Dog, climb on and fuck that bitch now!” she commanded loudly. Without hesitation, the guy quickly positioned himself between my legs. He grabbed hold of the spreader bar and forced it backwards further in the direction of my head, causing my arse and pussy to lift even higher off the floor. He shuffled on his knees into position and started pushing the precum-covered cock into my well-lubricated vagina. I closed my eyes as I felt the entrance of my vagina stretching open to accommodate its size. I moaned loudly, but then, after realising I didn’t sound like a dog, I quickly turned that into a loud yelp so as not to be zapped again by the prod. My pussy eventually relaxed enough and stretched open allowing his cock to slide into me. The accumulated cum provided adequate lubrication for his long and fat cock. 

He slowly penetrated me, not stopping until the total length and girth of his cock was deep inside me. It certainly made its presence felt as it filled every available space and stretched everything much more than usual. When he slowly withdrew, I felt every bump and lump that ran along its blood-engorged shaft as it passed through the entrance of my vagina. He only withdrew his cock far enough that the rim of the head was pulling against the underside of my labia. I was tight, and the girth of his cock was such that I could feel every millimetre of it.

In no time at all, I orgasmed violently, making my entire body shake and pull hard against the restraints. I couldn’t help but moan loudly. Even though I didn’t sound anything like a dog, Mistress made no response at all. I turned my head towards her, expecting the wrath of her electric prod again, but she was sitting back on her chair with one leg spread up over the armrest, masturbating as she watched me being fucked. Soon, “Big Dog” started fucking me harder and faster. The squelching sound of his cock ramming the cum from the other guys in and out of my pussy, was getting louder and louder. The smell of sex permeated every square inch of this room. He continued to pound my hungry pussy with his hot meat. Thrusting in and out of me, I moaned louder and louder, and within a minute or two, another orgasm flooded through my body, making me shake and pull against the restraints again.

I stared straight into this guy’s eyes, through his leather dog mask, as he fucked me. His eyes were cold steel blue in colour, piercing and intense, like he was already inside my head. He didn’t blink at all, he had me hypnotised at one end and impaled at the other.  This was too intense; I began having multiple orgasms, one after another and never seemed to stop.

Every time I caught my breath and looked up at his face again, his eyes kept penetrating my soul. He slid his mitten-covered hands under my arse cheeks and lifted me slightly higher to help with his thrusting and penetration. He fucked me like a machine. With every thrust, the muscles around his body seemed to flex and become much more pronounced. Oh my god, his cock stretched and filled my love canal to the maximum. So much so that my cervix was being displaced by this beautiful piece of sexually charged meat. I pulled my body up against the spreader bar using my ankles and wrists as leverage. I was instinctively doing this, like I was trying to get more penetration. I didn’t need any more; I was getting plenty; it was just an automatic thing I did in such intense erotic situations, and the pleasure that this guy was giving me.

I lost total track of time. I had no idea how long this guy fucked me, nor the others for that matter. I didn’t care; it was such intense pleasure that I never wanted it to stop. He fucked me like a machine; he didn’t falter with speed or rhythm. He used the entire length of his fat cock, making sure each time it was buried to the hilt before withdrawing. His muscled body was hairless and covered with beads of sweat from the physical and sexual intensity. I felt his grip on the spreader begin to tighten; his body stiffened, his rhythmical thrusting changed instantly to thrust in and hold, thrust in and hold. Each time, he spurted hot ejaculate deep inside me. The moment he began to cum, it triggered another intense orgasm in me. As I orgasmed, he kept pumping several more spurts of cum deep inside my pussy.

When he finally finished, he withdrew his cock and collapsed to the side of me, exhausted. I had never felt or seen a man cum so long and hard before. I don’t think there was a muscle on his body that hadn’t contracted as he ejaculated. Mistress opened the cage, took “Bog Dog” by his collar, and pulled him out of the cage. I was still in the restraints, panting hard. “Wow! That was intense. I’m so pleased with you, little puppy girl; you must be so full of cum. Surely, that’s enough for you to produce little puppies later this year”, Mistress said.

At home, a week later, my period arrived, no puppies for me.
