This story is for entertainment use this is a completely fictional story.

After my twins turned 18 I knew what would happen. From the age of seven I knew they wanted me. They wanted me badly my oldest already started to use me when he was 19. Now he's 21 and still in love with using his mother. He is my Dominant my wonderful baby is my Dominant and I love it. He hands everything as if his father would. His father left us after I had my last baby girl. He had a heart attack because he enjoyed watching everything so much.
That night my boys came back from work and I was lying on my special bed ready for them. It was a dog bed lying in the basement. I was already collared from my eldest his name is Sampson and my twins are named Dran and Sylvan. I find their cocks more important than their faces so. Sampson has the largest he is almost as thick as a horse and twelve inches. Dran was bigger than Sylvan Dran was the same thickness as Sampson but was only seven inches. Sylvan was average thickness and was seven inches as well. They loved their mommy very much.
They put my pet harness on and lead me to another room in the basement. This room was sound proof to make sure no one heard them doing things to their mother. Before anything started they brought in their sister that was only 18 she was curious and determined to be a fucktoy like her mom. They looked at her as Sampson walked over and explained in a soft tone “This lifestyle your mother is in is a very hard one and requires a high sex drive.” As Sampson talked Alexandra, their sister, just started to wet herself. But this wasn't pee this was her wetness dripping in her pants.
Sampson looked then roughly said to his younger brothers “Boys you can have mother tonight I'll have this little girl here.” He picked her up and she was completely ready and willing. He put her on the second bed and with a rough tone he said “Strip for me slut.” She was still shy but slowly stripped. Sampson like this he slowly got hard from watching his little sister be shy as soon as she took off her panties he seen her dripping wet young pussy still nice and tight ready to be opened. She spoke “Bubby I've been wanting you to do like you do mommy and cum in her please Bubby cum in my fertile little kitty.” Sampson's eyes opened wide and he couldn't handle it he ripped off his clothes and instead of being on two separate beds the boys decided to have us be fucked on the same bed. Sampson put his little sister on all fours as well as me and he gentle slide his cock into her little pussy he held himself trying not to go insane. Dran had put his cock in my mouth and Sylvan in my ass. They roughly went at it using me well. They didn't notice but I had another baby bump again this time it was from Dran. He was going to be a proud father again.
Sampson couldn't handle it anymore he just start to thrust harder and dig deeper making his sister scream she screamed “Fuck me Bubby fuck me hard. I love you Bubby I want your baby Bubby I want to be a little breeding pet. Please Bubby cum in me. Cum in me hard.”As Sampson fucked her put a gag on his sister to keep her from screaming too loud. Sampson prepared to thrust hard really hard he fucked her like he had never fucked anything before it felt so good to him he tortured her pussy like none other as she whined and whined. He found himself more and more excited. He was rougher than ever. Pounding like a freight train into his little sister and this point she was screaming he pulled her hair and did one more thrust. He blew his load in her hard throbbing deep inside her fertile young pussy.
He took the gag off and kept his cock in her like an animal would until he was soft. By that time he had already impregnated her. She lied on her back wide eyed from her big brother. She had gotten up slowly and walked away lying in her bed she thought. Wow I have big brother's baby inside me now. Yay I'm just like mommy now. I'm loving this thank you Bubby.

In the next few days Alexandra went through my pregnancy test like no other waiting for one to turn up positive and finally it did. She was so happy on that same day it was her birthday. She walked down to the basement not to do anything but to watch me be used. They were already inside the sound proof room using me. There was a viewing window so anyone could watch me be used.
That day she watched me be fucked hard. On the inside I was on top of Sampson taking all his cock inside of my pussy while the twins watched as I grind on him as he moaned to me “Whose my favorite slut? Whose the best mom in the world?” I replied humbly “I am. I'm your little slut I'm the best slut I'm the best pet ever.” Sampson wasn't into as much and stopped he knew his sister was watching and quickly let himself go in me. He walked out and saw his sister sitting there.
While they talked I was milking Dran's cock with my mouth while Sylvan's was in my cum filled pussy. Dran I sucked and deep throat hard while Sylvan fucked me deep he went harder and harder making me moan in pleasure. Sylvan smacked my tits to get me to be louder and with one smack milk leaked out. Both Dran and Sylvan stopped and latched on to my tits suckling like animals. They still loved mommy's milk. They both played with my pussy or ass while they drank.
A few months later as both Alexandra and I started to show. We both had twins so we looked months ahead of what we really were. Alexandra wanted to experiment with me while the boys were away so I took her to the room and let her tie me down. I gently said to her “Now sweetie get that wide crop over there” She grabbed it and looked at my pussy. She started to whip it slow. The most painful way to do it she watched her mommy wince and whine. She liked watching me jump as she whipped my pussy. She didn't stop even after it turned red. I had to stop her. “sweetie you can't keep doing that after it turns red it becomes to painful for mommy to handle” I explained to her. She was enjoying seeing me in pain so much. She noticed a diaper on the wall “Is this for you mommy?” I nodded I got up and put the diaper on “it's for me to pee in at the command at your brother's command but you must call your brother daddy now. He's your baby's daddy he is no longer Bubby.”
She looked at me and hit my back with the crop “Shut up slut. She dropped the diaper from me had me bend over and she grabbed the paddle she spanked my ass and spanked it hard with each hit she got harder until my ass was beet red. After that Sampson had walked in and took her away “Baby girl let me handle this momma's pussy is ready for daddy's cock.” He took off his pants and before he fucked me he had me on all fours my face on the floor and relieved himself on me. He peed and it drizzled all down my back to my hair and around to my udders. He loved to pee on me so much. Afterward he had me sit up and watched his pee drip from my hair down my body.
He then put me on the pee bed in the same position to smell my own pee from months of peeing in it. “It's time to get you dirty slut.” He roughly said to me. He started to fuck me softly with only part of his cock in my pussy. He couldn't stand this he thrust his cock all the way in and just went at it like a horse in a mare and a dog in a bitch. He was thrusting hard but fast in me. He dug deep really deep so deep I screamed. He was enjoying my pleasure but pained screams. He loved hearing them every time. He fucked and fucked and fucked cumming more and more my pussy almost filled to the brim with his cum until that day he decided to do something different. Something he has never done. Something no one but Sylvan has done he grabbed the best lube possible and an applicator. He put as much lube in my ass as possible and flipped onto his back. He grabbed my body and started to suck from my udder I knew what that meant. He wanted me to take his cock as thick as a horse and put it in my ass.
I slowly put his head in clenching my teeth. His head was the hardest part I kept trying but it was so hard to fit him in my hole. He then got tired of it put me on all fours and went and tried himself he gaped me open rubbing his cock in anal ease and tried himself. He slowly put his head in as I clenched my teeth. It hurt so much but I enjoyed it. Barely being in there I clenched my teeth as he had gotten the head in and everything else just followed with it. I felt myself jerk up and clench the bed. This was going to be the ride of my life. I heard him moan loudly he tried to control himself his pupils dilated he turned into a beast. I felt him grabbing tightly on to my hips his canines showing as I looked back I seen an evil glare in his eyes.
