In one week, I was having a birthday. I was going to be thirteen, and my parents were going to throw me a party. But today, my dad pulled me aside. He told me about a second party that he was going to give me, right after my first one. One that only certain friends were invited to. When my dad turned thirteen, his father gave him this same party, as well as his brothers. And when Grandpa was thirteen, the same thing happened to him as well. So it was only fair that now I get this party. He said I was going to become a man. And so were some friends as well. I invited only my best friends Jimmy and Frankie to this special party, only telling them that it was a special sleepover, because that's what my dad said. They were excited about it, just like me. When my birthday party came, I had plenty of friends over for cake and games. My cousin Hank was over too, and Dad said that I could invite him tonight. Jimmy and Frankie agreed as well. It was a little strange that I didn't see Mom around much during my party. Maybe she was getting my second party ready. She did come out for cake, though. After games and presents were done, all the other guests left. Dad had Jimmy, Frankie, and Hank in the kitchen, eating leftover pizza. Once we were all done, Dad led us into the basement for the second party. Once there, I saw why Mom wasn't around much. She was laying out on the floor naked. We were all amazed that this was happening. Dad told me what this party was. Back over a hundred years or so, men in our family felt that a boy should become a man with the help of his mother. So they got to have sex with her, and it had turned in time to a party event, with a few trusted friends and family. So that's why the other boys were here, so that they could be a part of the fun as well. Hank knew right away, since he turned thirteen last year. His dad is my dads brother. He told me about when he had sex with his mom. She let him do whatever he wanted. He said that they watched porno movies and kept having even more sex. So I started to take off my clothes. Dad told the other boys that they would have to wait their turns after me, when I was done and ready. Mom said that she would let me do whatever I wanted, and that there was a good porn ready if I needed some ideas. I said that I wanted to start somewhere, so I went to her and kissed her on the lips. We kissed like that for what seemed like forever. It was great. I had to break the kiss sometime, and I then decided I wanted to touch. I felt her soft skin, her boobs and nipples. I felt her stomach, her trim legs. I took a good look at what she called her pussy. I really liked the look of it, and I could smell an amazing smell from it. When I touched it, Mom moaned. I thought she was hurt or something, but I realized that she was enjoying my touching. She told me to spread out the lips and take a good look. I pushed open her folds and saw the most amazing thing ever. Mom then said that it would taste great. I believed her, so I leaned in and gave it a kiss. The juices that came from her pussy tasted amazing! I enjoyed it so much, I kept kissing, sending my tongue in. Dad came over and showed me where was a good place to lick, and how to -finger - her pussy. I went back to sucking on the clit, as Dad showed me. Mom was so excited from this, she was moaning loudly. I kept going forever. After some time, Mom had to push me away. She then looked over and saw that my friends were all touching themselves. She told them that if they wanted to, they could jerk off. But if they did, they had to aim for the jar so she could drink the cum later. Mom then told me to walk over to her face, so I could get my fun. I didn't know what she meant until she grabbed my penis and took it in her mouth. It felt great! She sucked on it, licked it up and down, even sucked on my balls. I couldn't contain myself, and I just started to cum and cum, right in my moms mouth. And she swallowed every drop of it. After making sure every last drop of my cum was in her mouth and my penis was pulled out, she let me sit back and relax. She told me how much she loved me and was proud of me for being a man and giving her such a good treat. When I looked at my friends, I saw that none of them had actually jerked off. Mom called over Jimmie at that point. When he got to her face, she grabbed his penis and started to suck on it. I have never seen him so happy. Mom kept sucking on him until I saw him start to stiffen up, and then Mom swallowed. I knew what happened for him. After that, Frankie was right at Mom's face, waiting for Jimmie to walk away. Mom didn't have much of a chance to recover, not that she wanted to anyway. Frankie had shoved his penis in her mouth as soon as Jimmie was out. Mom sucked on it, and played with his balls until I saw the signs of him cumming. Hank said that he was going to wait until after the end, just to see what all happens. Mom then told Jimmie and Frankie that they had to wait now, because it was time for me to fuck her how ever I wanted. I climbed up between her legs, and she grabbed my penis. After jerking on it for a few moments, she guided me in to her pussy, and I thought I was in heaven. So soft and warm, I pushed in fully. I then knew what I needed to do, and I pulled out a bit and pushed back in. Mom started to moan, and told me to go faster. Faster and faster I went, until I pounding my body against her hard. It didn't take long, but it felt like forever, and I pushed hard into her one last time and start to cum in her. I sat there for a few moments, when Frankie asked if they were going to have a turn next. Mom told them all that I got to do whatever I wanted first, and that the other boys would get their turns after I was done. My friends all were a little upset at that, but Mom helped me figure out what to do. She told me about the sexy way of cleaning up, and I went right for it. I pulled my dick out of her pussy and shoved it in her face. She took it in her hands, let rubbed it all over her face with her juice, and then licked it all off like it was a Popsicle. She told me that she loves to lick her juices off cock after fucking, and sometimes when it isn't her juices. Hank spoke up for a moment and suggested that I play around with her ass. Mom heard this and squeaked. She then turned over and pushed her butt in the air. She spread out her butt-cheeks and I saw her anus. I didn't know what to do when dad told me to put my finger in there, then let her taste it. It was little weird, putting my finger up a butt. Mom seemed to like it, so I did like I would to her pussy. She kept moaning that she wanted to taste it, so I pulled out and fed her my finger. It was like a favorite food for her! I decided to see what the big deal was, so I leaned in and took a taste. When I did, she told me how good that felt and to stick my tongue in as deep as I could get it. It didn't taste like poop like I thought, but actually somewhat tart and sweet. I kept going, pushing my tongue in as far as it would go. I was quite enjoying this. After a few minutes of this, Mom told me to kiss her again. I pulled my tongue out of her butt and walked up to her to give her a kiss. We kissed for so long, she was sucking the taste out of my mouth. Once done with that, she told me to fuck her asshole. Dad handed me a small tube of something called lube, and he told me to spread it all over her butt and my penis. He showed me how to work some in, and how slippery it was now with the lube. He said that I should be doing it this way so that I don't rip her apart. Once she was slippery enough, I stood up and put my penis at her butt-hole. I pushed in, and boy, was it tight and hard. It seemed like her pussy was a better fit for a penis, but this was so much better. In and out I went, I was an animal. But it didn't last very long. I came in my mom's butt, grunting hard. I was breathing hard when I felt my penis fall out of the ass. Mom had moved out and started to suck on me, cleaning anything off me. I let myself fall back, and mom just kept licking on me. I almost fell asleep, but Dad shock me awake. He asked me if I was done. I said for now, and we could let my friends fuck Mom for a while. Frankie was the first one to run up and started to finger Mom's pussy. He was really eager, and Mom started to laugh. She told him to slow down and then showed him how to do it. Once he got the hang of it, she pulled his fingers out of her and tasted them. But Frankie didn't waste anytime at all. He climbed up on her, got in position, and shoved his dick in her. He pumped in and out, and Mom moaned the entire time. It didn't take him long, but I saw him shoot in her pussy. I don't think he was done shooting before he pulled out of her and had Mom sucking on his penis. Once Frankie was out of the way, Jimmy asked her if he could fuck her in the ass. She turned over, he grabbed some lube, and then he started to push in slow. He kept going slow, but started to pick up more and more speed until he was slamming himself against my mother. She grunted with each push when suddenly, Jimmy pushed hard against Mom and grunted himself. Frankie told him to have her suck him clean, but I don't think he heard. Jimmie pulled out and sat down. Mom turned around and started to suck at Jimmie. She heard Frankie. But then Hank stood up and kept Mom at Jimmies penis. He stood behind her and took off his pants. Once his cock was in view, he shoved in her ass and started to fuck her hard. He looked at me and told me that ever since he started fucking his mother, she has been a sex-slave to him. His Dad has a new girlfriend that comes around, but his Mom does whatever is asked of him. He said that when he is watching television, she keeps her ass ready for him just in case. She sleeps with him every night and they fuck all the time. And he tells her who she is allowed to fuck as well. He said it is the best thing in the world. While Hank was talking, I barely noticed that Jimmie had swapped out for Frankie. It didn't take him long to cum again. He pulled away and sat down next to me, looking pretty tired. Mom looked at me and told me that she will be just like Hank's mom to me. From now on, she told me, she will be my willing slave for everything. Sleep where I tell her to sleep, fuck how I want her to fuck, clean my room and cook my meals. I can even pick her clothing from now on, she said. Dad came over and shoved his cock in Mom's mouth when she was done talking. He reminded me that my sister turns twelve next month, and that's when we break in the girls in this family. Once that happens, he will never be able to fuck his wife now that he will have my sister to use and abuse. I asked if I could fuck her too, but he said I would have to wait my turn at her party. Talking about my sister really got Dad going. He started to pound into Moms face like he was fucking her pussy, and she took it all down. He slammed into her face one last time and grunted. I knew he just came down her throat. Hank came at that exact moment as well. Mom didn't waste any time and turned around to suck Hank clean. Once Mom was done with Hank, she crawled over to me and told me that she loved me so much, and that's why she is going to do everything I ever tell her to do. She said the only rules are that if Dad tells her to do something that I can't stop that and that she won't be able to do any of my homework for me. But if there is ever a time when he needs to fuck his Mommy, or wants one of his friends to fuck his Mommy, she will do every little thing she is told. And once she was done, she laid down next to me on the couch and snuggled up, using my cock as a little toy. I started to fall asleep when Dad told Mom to take me to bed and that he was going to talk to my friends.
