Got a Dog, he wasnt neutered

I found out the hard way that the seller told me a lie.

This is my story.I am a Young skinny boy and not gay. I had sex once with my ex girlfriend but that was it. It started all years ago when I was 18 left my family house, got a job in a different city and started working there. Finding new friends was kinda hard for me and therefore I decided to get a dog to not feel lonely. I checked the Internet and surprise! I found a small beagle mix that was cheap for sale - just 100$! He was neutered, chiped and very peaceful they said. Also he was a dog for beginners! I never had a dog so good for me too. Of course I took my chance and immediately went over there to have a chat with the current owner and may take him home. Beans, as this was his name was lovely and after just one walk I said yes. Im going to cut this short, bought all the stuff needed later the week and got beans right after. It was a happy ending for everyone. I loved beans so much I took him everywhere I went. At home in my small one room flat of course he would sleep in my bed. But then I started to notice a strange behavior. He started to jump around sometimes, especially after when he had met female dog on the walk. One day he even humped my leg! This behavior went on for weeks. I tried to contact the old owner but couldn't reach him and then I read an article that even neutered dog do that sometimes. So I told him NO! And was sure that it was just a lag of training on my part. Well I really tried to stop the humping and it actually stopped for a while. Long enough at least to forget about it. But beans had never intended to actually stop. One day things then escalated. At first we were just playing around. Growling and fighting over his toy and stuff. But then he really bit me hard. I was shocked. And he then immediately tried to hump me again. Since I'm much bigger I just stood up and got angry at him. Which ended with him whining on the floor. I told him to sit in his basket and after that I decided to get ready for sleep. I actually had a habit in the summer to not wear pants but just some boxer shorts at night and therefore changed my t shirt and was getting undressed down below too. I was looking for my sleeping shorts and got on my knees, thinking that I threw them under the bed somewhere but I was wrong. So this is the final position. My naked ass, me on all four and beans jumped up. And before you judge me about what happened next, just think about it. Beans is a beagle mix! He had not the body size to either scare me nor would I have thought he could mount me! Also I really thought he was neutered! So he got up and put his paws on top of my ass and humped in a weired way. I screamed "BEANS!!" And for a second just stood there on all fours trying to cope that I couldn't teach him to stop this behavior. And then it happened. Little beans was smart enough to understand that he could not get a thrust in because of the size difference and actually jumped upward with a full body powered thrust. BUMP! "NGHAAARGH!" - I screamed! This little fucker did it. He jumped upwards and his never before seen dick pulled out and went full inside my anus. I actually fell over a little. Pushed by his thrust and the pain of course. And he fell over me on top too. If I would have stayed as I was , he probably would have thrusted out and that would have been it. But no, I had to fell over a little so he could too and therefore lay on top of me. But how could he get inside that fast?! Well dogs have an actual penis bone. No shit. I never knew and therefore they can penetrate you even not really "hard". For dogs getting "hard" is something different anyway. So he jumped up full thrust into my hole, flipping me foreward with him on top.
And he started to thrust full power. Guys if you don't know, I will tell you know. Beagle have, compared to their size, really REALLY big dicks. Like they can get massive. At least the size of a human dick and bigger. And I started to feel that because his penis started to grow in size inside me! Yes, this is actually when a dog gets "hard" . This was just his third thrust or so and probably 2-3 seconds into the attack when I felt a "filling" feeling from his growing dong. I actually did afterwards what everyone would have done. Of course I wouldn't just stand there and take it. I let myself fall flat to the ground while stretching my legs and arms out. I could feel a pulling sensation in my ass too, since this move would definitely pull myself away from what ever was on top. But this moment I also learned a horrible lesson about dog physics and genitals. If you don't know, a dogs penis has a knot that can grow the size of a tennis ball. Even little dogs like beagle can grow that size! Okay Maybe not that big but for me it was enough since my ass was not ready nor trained for this. My ass was normal as everyones. What it does is, it locks the genitals from dogs together to ensure the pregnancy. This tie can hold for hours. But there was no pregnancy here! But still this would mean I will get breeded now and I could not stop it.
So imagine this.
Me on all four. Beans coming over touching my ass, humping and then BUMP the big thrust jump hitting the hole, a loud screaming, both of us falling a little over, beans thrusting a second time me falling to the ground stretching my legs out and holding my head. His dick in the meantime entering my hole, while falling over, growing in size and his knot filling with blood too. But that wasn't just it. Dogs especially the ones that had not been "milked" in a while start to cum and pump their load like immediately once they enter anything to dump it. And so did beans even with his first thrust he must have shot his first precum inside me, which I could not feel at this moment I could later because it would add up over time till I could feel it. He entered my anus and started to fill me up while his penis grew and his knot knew the assignment and grew with it into a size that would ensure no escape..i was trapped...and more I guess...I fell to the ground and stretched my legs screaming in pain when I felt the pulling on his dick but he just did not fall out. I felt a pinching pain once his knot reached my sphincter and I even pushed like I wanted to take a dump but this wasn't going to happen. His knot was like a butt plug and it wasn't even its full size yet. Beans was disrupted for a second from the fall, but now, on the ground, not directly on top of me anymore and his paws were able to reach the ground, he went full beast mode. We were still locked and his dick was filling me up while his knot still grew. I could feel the tension inside me of this massive thing shaking up and down! And beans started to thrust like this was his last chance of emptying his balls. Guys this was just like 5 seconds into the action!! I felt his thrusting and it caused immense pain because he was ripping against my sphincter. I also really did not had realized what was happening right know! It happened so fast and all I knew was that I'm in pain and had to stop it. I was lying there for like 4 seconds or around 5 thrusts before out of pure misery and pain i raised my hips a little to find a less painful position - Lifting up beans again, who fell over on top of me again. His paws were just hanging on me now but he would not fall off. He used his front paws to clinge on my hips while his back legs were just hanging there... thrusting.... filling me... But that took a lot of tension and pain from my sphincter that I could not handle. So here am I, on the floor face down ass up with my dog beans tied together on top of me, with his dick inside my ass pumping load after load while thrusting himself up and down. 5 seconds into what I would call a rape scene. I still hadn't figured out what was happening. One second beans was at my back, the other I was in immense pain in my ass and something pulling on it while growing in size inside me. I also felt kinda watery inside..But now we had reached the final position. The pain was bearable and beans humped and thrusted me for another 10 seconds while I was just trying to stand still. I had no real thoughts just to make it stop or hold out until what ever was happening is over...until...well I felt a rush of... orgasm...i grunted. His thrusting actually did something to me. My body was going to betray me. We were fighting for like 10 seconds like this until the final position and then he was just fucking me for another 5 seconds before things turned. Because It was enough time for his knot and penis to grow into enough size to massage my prostate from the inside. For the once that don't know the prostate is like the g spot of a woman but for men. And if you press it just long enough every guy WILL cum and have an orgasm even if his dick is not hard (called milking). So yes, It means there is basically a button inside every guy to force them to cum and milk them, even if they don't want to. But the prostate is also necessary to get hard. And at first I just grunted in surprise of the strange feeling. Pain and pleasure were shaking hands you could say so. There was pain but then there was pleasure!!! I could not understand what was going on and just stretched myself a little again....and then... PURE ORGASM...ngghaaaa!!!...by accident I had adjusted beans thrusting knot and dick perfectly to my prostate. Pain was no longer the priority. Instincts took over. My brain said DO IT. And beans was fucking my ass so hard that my own penis got rock solid and started to swing around. I was holding position now like the instinct that told me to do so. The pleasure was intense, like nothing I had ever felt. The harder my dick got, the stronger the orgasmic agony. I screamed "beans! Beans! Stoop!" While my inner walls from my anus started contractions and holding his knot thight. Every thrust from this point on wax sending waves of orgasms through my whole body. "BEANS!!!" I screamed!!!! My eyes turned upwards. My screams seemed to just encouraged him to thrust faster. Not only his dick and knot were fully erected at this point but my penis was too. My brain was completely out of business trying to deal with the orgasmic tension that was contracting from anus against his knot like an electric shock to my brain. Every thrust was initiating another mindblower...And then it happened...just after less than 30 seconds into this fucking my anus contractions started to become to reach all my genitals and started my dick pumping. But not like normal. Usually when you cum you orgasm and then pump like 10 times and you are done... But no, not this time...I shot a load myself. But instead of ongoing pumping and being finished, my pumping was connected to the contractions of my anus. And that were initiated by beans thrusting! So I was only cumming when beans was thrusting. So basically I could only cum and shot a load when he was cumming and filling me up. I literally shot the first load up to my face and like a bottle of soda that was shaked and opened, with every thrust from now on i would cum too. I actually think I did try to hold it for a second, but the very moment I would try to keep his penis in check, with butt pressure and try to not cum, the absolute overpowering and stunning orgasmic agony made me let go as if a shock collar was around my balls. I had to let go and continue! Imagine this... me on the floor face downs, ass up with a beagle thrusting like hell inside me, shooting his load deep into my organs while I was shooting loads of cum out of my penis. Actually after the first "explosion" it was more of a slow dripping, kinda like you empty a toothpaste - but beans was the one emptying it while filling my ass up...it was pure orgasmic agony. My genitals and anus was all I knew and I didn't wanted it to stop. And it seemed like it would go on forever...but then....out of nowhere, it was over. Beans just stopped. He was still pumping cum in me though but he stopped thrusting.. thank God actually. A male human can only have that much orgasms before blacking out.
I was lying there with beans on me, falling to the ground again with my hips and we both were completely exhausted. I started to realize that beans just had raped me...and that I had the biggest orgasm in my life. I still felt a little aroused just by the dick inside me pumping but I also had a really watery feeling in me. Trust me guys this wasn't over yet. We were locked like this for 10 minutes. Beans tried to stand up and turned around pulling on me. Luckily now he was listening again and stood still when I told him to but the watery feeling started to cause stomach cramps. I really had the urge to poop. I felt like the pain you get when you had eaten to much chilli. The pain got worse and I pushed like I was taking the biggest and most important shit in my life. The pain was crazy! I pushed like that for another ten minutes until finally beans knot had swollen down enough to get out! I farted so fucking loud when he pulled out.. followed by a wave of shit and cum as if I had diarrhea. I immediately jumped up and ran to the toilet where I was sitting and shiting cum in absolute horrible pain for the next hour. Once I was finished my butt was hurting like hell and I got back into my room and had to clean the cum- shit mess that had started to dry on my floor. All while beans was in his basket sleeping with a smile. Once this was done I finally went into my bed too. I let the TV running and was lying on my stomach. My butt was burning so much. It was just this moment I realized what had happened. Like a rape victim it was only this moment of peace I could think about what had happened. I was on the ground on all fours, beans jumped up on me tried to mount me, thrusted into my ass (2s), we both feel over, i layed down but his knot was preventing the exit (5s), then he was fiercely thrusting and fucking me until the pain was not bearable anymore (5s) i raised my hips a little and got fucked another 10 seconds till my dick got hard and orgasmed..then another 30 seconds of pure agony of pleasure, cumming while beans was filling me up...this had happened in less than 1 minute!!! And afterwards we were stucked together for around 20 minutes which half of it was a painful urge to poop and hour on the toilet and 15 minutes of cleaning. I remembered every second of it till now. I felt so embarrassed. I actually wanted to cry for a moment. I could never EVER tell anyone about this. I got angry a little against beans I actually woke him up and pulled his basket into the floor between the living room and the toilet and told him to sit there. He whined not understanding why but I was so pissed. This little fucker just raped me! But I also felt aroused by the moment I saw him lurking at me through the doorway. I shaked my head and tried to sleep. I actually had to poop several times that night again but once we reached the morning my ass felt fine again. At least for a moment. We had our routine and I went to work. While working I really felt strange. There was a nice horny looking female blonde coworker I usually masturbated to in my break but this time I just couldn't get it up. I felt horny but my dick was just not responding. I tried to jerk it but I really felt some sort of pain from my prostate area. I actually was shocked and going to cry. Did beans not just raped me but damaged my prostate? Do I have to go to the doctor now and tell this embarrassing Story? I had tears in my eyes for the rest of the day. I got back home had my routine with beans but still was so angry and hateful about him. I actually got my phone out and Inserated him. I wanted him gone! He broke me! I felt so miserable. It was weekend now by the way. I drank a lot of alcohol and just blacked out. Of course beans had realized that I hated him now and he was so obedient now. He really tried to make things right as good as a dog could but I rejected everything. The next morning I woke up to a big surprise. After nearly two days my penis was back up again. And fucking crazy he was! I woke up like I had a line of cocaine. A crazy feeling of hornieness woke me up while being welcomed by the biggest boner of my life! I found out later that a good prostate massage is good for its health and does increase fertility. After what had happened to me i guess the prostate just needed a rest but once fully recovered my urge to cum was present like it had never been before! I woke up saw my dick in pure happiness and couldn't resist to immediately start to stroke myself. But it didn't made me satisfied... My ass actually felt...i don't now...gaped?! And it screamed for a filler!!! I was so fucking crazy horny. I pushed a finger into my anus while stroking my dick but it could not satisfy me. "WUFF!!" - I stood still. I looked down to the bed. Beans was there shaking his tail in excitement and I don't know what I was thinking. Probably nothing. It was all instincts.. I jumped down to the ground presenting him my ass. For a mere second I just thought. WTF AM I DOING!???!! And was going back up. But beans understood what he needed to do to well..just the second I thought WTF?! BUMP!!!! Beans was back on me. But this time was different. I was already rock solid. Hard as I had never been before and I didn't try to lay down just stretched myself in position. AAAAAAAARRRGGHHG I grunted so hard in orgasmic agony. This was happening now but on my terms!! I was doing a plank while beans started to fill me again and I could feel his boner and knot swelling again. This time there was no pain. AAAHHH UGGHHH ARRRRGHHH "WUFFF!!!" Beans joint the grunts. Was contractions started again holding tightly to his knot and we both started Cumming in union again. Every thrust was a finisher. I emptied my balls to the point nothing was left and dripping was no more but I still had endless orgasms. I was grunting the whole time now until he stopped again..but even once he stopped I kept orgasm with every pump of his balls. "Good boy" i said while trying to keep it together until he swole down. But this time he pulled and just popped out. No long waiting, no pain. Leaving all the cum sealed inside my ass. The pull out made me cum one last time and I could feel his cum running down my intestines. I waited for the poop feeling but it seemed that I started absorbing it a little bit. I could stand up and only after like 20 minutes I had to poop. After my toilet and a walk we both layed in my bed cuddling..i deleted the Insertion and even though I didn't wanted this to be our relationship, the first time was forced, now I wanted nothing more. I do have a girlfriend now by the way but she does not know about this special relationship with my doge. Love you beans🫛
