Unwanted Dog Sex: The red knight rises

Hi Guys i hope you have read the first part because otherwise this might be confusing but this is what happened just last week. My butt is still hurting a little bit... For everyone who doesnt know me, im a average sized guy and very skinny. I do jogging a lot and therefore have a big ass and strong legs. I just started College and live with two other Guys in an Apartment that we share. There is James, who likes to party and Gus who owns a Rottweiler called Rottie that will play a big role in the new incident.
Since the first mount some weeks have been gone. And in the begining i had to deal with the consequences from Rotties last rape. every poop i took felt very painful for quite some time and i was also leaking. His knot has streched my hole so wide that it was sort of not closeing right anymore for a while. But after that was healed i was fine... Beside that my mind and Body had changed too. I was ready for more. The endless orgasms from last time probably had damaged my brain because i wanted him to mount me once more. I wanted to get filled Up again. My Body was also starving for more. I never Had this feeling before... You know when i felt horny, usally i would get a boner. But since Rottie had screwed me Up i felt the horniness from inside my butthole too. I could feel my inner walls close to the prostate tighten Up and my butthole got loose. There was also a tingling sensation between my hole and my dick that felt sort of hard when my dick was throbbing. You cant Imagine this kind of horniness. It was sickening me. Everytime i got a boner this feeling rushed through my body and stayed down in my butt area like a warming pillow inside me. But it Also was like an itch i couldnt Scratch. . Trust me Guys i jerked of so hard but i couldnt get rid of that feeling. The worst part is that after jerking of nearly ten times in a row the "itching" went worse so i went crazy and pushed my finger in my butthole and tryed to pull the trigger but even though that felt right i wasnt able to push the button it was like EVERYTHING Inside me was itching and i just wasnt able to scratch everything at the same time...and so i was forced to stay horny and unsatisfied.
But Then it happened again! Like a miracle - Gus was meeting with His Boyfriend again (He was gay remember) but since His Boyfriend felt sick He asked me to take Care of rottie again. And James? Well He wasnt around either! He was at His parents place. I was so lucky i thought. Rottie...this damn dog who did this to me...He would BE the help i needed to finally get the itching scratched. When Gus announced that i was so horny the whole week. Then it was friday afternoon and James left and then Gus came up to me gave me Rottie and left too.
Now i was alone with the dog... but i wasnt sure If i should do it with him right now. I was scared that James or Gus could have forgotten Something and would come back. So i decided to wait until saturday.
I couldnt really sleep that night because i was so aroused. I jerked Off two times but i just couldnt wait. It was only 7 o clock in the Morning. I called rottie for His walk but only let him pee and then we went back inside.
I was aroused, i was horny but i was a litte confused too. How do i make rottie fuck me again? The last time it was rape. He just pushed his dick inside me and Then blew His loads of semen. So i got naked at first and got on all four. I showed him my ass and then waited. I could hear him breathing but Not moving so i called him "Rottie Go! Good Boy! Go get it!" - but He did Not react. While i was doing this my dick wasnt even hard - i was nervous, like really nervous, would it hurt again? I remembered all the pain at this Moment. Maybe thats why He didnt do his move. But before i could continoue my Phone vibrated and i stoped to see who it was. It was Amber from my class. Well since i wasnt gay like i told you in the begining, i also was looking for a girl to mate with. Amber was a nice Girl. She was perfect! Big boobs, perfect ass and as it seemed interested in me! I asked her out last week and she finally answered that on tuesday after class she would agree to a coffee! YES!!!! I thought but Then i looked at rottie and felt guilty. What was i doing??? How could Amber date a guy that gets fucked By a Dog!? I didnt felt horny after that thought anymore...eventhough my dick was a little erected By the thought of amber.
But i didnt took rottie into account. He must have seen my dick swelling a little and decided NOW is the time! He was starting to jump around me and i Pushed him back. I tryed to calm him down but He wouldnt listen. At First it was playfull. He tryed to push me down to the ground but i wasnt having it. I screamed NO! and Then He stood still for a second and then He growled...really angry! I was scared. What did i do? I didnt had the dog under Control anymore and He seemed pissed. I ran around the Couch naked, followed by an angry Rottweiler, reaching for the Toilet but He was faster! He jumped me, Bit into my arm and pulled me to the ground! I was geting mault By rottie! He scratched me with His claws until i was bleeding because i was trying to stand up again while my arm was smashed By His bite - i swear i Had tears in my eyes, i was actually scared "rottie please" i mumbled and Then He jump again but not to mount me. He bit my neck....i stoped any movment at this point and got on all fours. You got any Idea how strong a dog can bite? Well at this point i knew and He Had my neck. He was growling. And with every growl He bit harder...would He kill me? I cryed a little, i was bledding...He growled again, biting harder. It was already hurting very strong. What could i do to stop this? I looked back and Forward and Then i saw it...His penis was showing a little and Then i knew what He wanted...i Had No choice anymore. I didnt wanted this but He was mauling me. I started to move...slowly under the dog He moved His front legs so i could Go under him...He was growling Again but this time not biting harder...it seemed that this is what He wanted. Now i was under him but He didnt moved and i neither...i did what He wanted right? But Then i understood He wanted me to raise my ass...oh god! I thought to myself what have i done! I would get mault By dog or fucked - He gave me this choice. I didnt had a Word to say in this. It was mault or fucked. So i thought a minute about my choices and thinking about going into the Hospital wasnt an Option. So i slowly moved my hips up. My asshole was lining up with His dick. And Then i Pushed back until His tip was touching my hole.
I dont know why but the Moment his tip touched my butthole i actually got aroused and horny again. My Body was betraying me again. My dick went rock solid and my hole got loose again while my inner walls tighten up. I was tingling all over the backdoor. Then He grabed me with His big paws and he let my neck go! God was i releaved! But not for to longe. The Moment he let the tip of His penis shoot a load and entered my hole "nghhaaa" i groaned. You see it did not really hurt because a dog Penis in His normal state is actually Not much thicker than a finger only after they entered a hole the penis grows in size. So it Happend that He coul easily enter my untrained butthole. I was suprised too. He went in like it was nothing. I pushed myself even against it. He went in and Out a couple of times but everytime it got harder because His knot was swelling fast and Then it couldnt move out anymore. Every thrust blasted my mind into orgasm. I told myself not to cum! This is a rape again! Im in Control at least over my Body! The swelling, the filling with seemen, the heat...i ejaculated immediatly after the knot was stucked. I was moaning loudly. And felt ashamed for a second but This was far from over. Rottie was in charge now. He would decide when i stop orgasming. He really pushed his knot upwards while i tryed to hold my butt down. It was just like the last time but even better! Last time was a suprise, this time i had an urge, an itch to scratch. I came and i came, i tryed to hold it in but my whole Body was tingling while wave after wave of orgasm ran through me. Yeeeeeessss! The itching!!!! His knot was pushing it!!! Finally a scratch!!! I was shaking in pleasure. He was humping so fast. I still tryed to not cum. I need to stay in control of my body. But Then i felt strange...my whole body was tingling and my dick was pumping load after load until my head started to Vibrate...i cant explain it better but at first it felt like i get a stroke but Then i realized it was a build up. I was braindead at this point only Orgasm in my head. My eyes upside down Holding on to the feeling of orgasm. I was moaning so Strong...this ...this was different. The build up was to strong and it Happened even though rottie was forcing ejaculation already. Was ist because i mentaliy tryed to fight it! Anyway i was Screaming like a pig, the orgasmic Vibration was to intense. My Dick stoped for a second to ejaculate. I could feel it geting charged Up in my dick. Did i just stoped it? For like three or four thrusts i was Holding it in. But for what price it was torture And rottie must have noticed. He clinched his pawes harder growled and Then started a new move. He pushed himself nearly over me,If the knot wouldnt tie us together He would probably have fallen of. But By doing so he got His knot and dick to move up and down depper and deeper through my insides lubricated By His seemen. It broke me. My inner walls were so tight to stop him from moving. He just smashed them. They got loose and By doing so i released my stored cum in a big orgasm. I was Vibrating all over my body. My upper body went numb under this condition. I layed down my upper body and face in the ground. My ejaculation was reaching my face. So while rottie was pounding me and filling me Up i was forced to cum into my own face. The build Up and Release was just to strong. I gave up all resistance. In this Position rottie was able to do his Trick every thrust anyway. How could i stop this? I let him finish. And then we stood still like the last time. Fuck...i still had "aftergasms" i was ejaculating even though He Had stopped. And then we had the old tie Problem. This time He seemed tired at least. He was laying on me for like 30 Minutes and Then He poped Out. The amount of cum that was flushing Out my hole with His dick was huge. It seemed twice AS much than last time. The stroke like Feeling also got down. I was so satisfied and ashamed at this moment. Oh god was that good but what about Amber...i cant sit for at least a week now. What If she ever finds Out? I was disgusted By myself. Then i looked at rotties face - i cant watch over you anymore i said. I was trying to Fight him off and i lost. How am i supposed to take care of rottie now? Let me rape every single time? Submitt to it? Accept it? ....some part of me wanted though but my other part knew that this was wrong. I had to stop this but how?....Or should i give in? This decision would be decided the next time i thought..i came one last time that Interrupted my thought and Then i stood up to cleane Up the mess of cum we made.
