My husband had already left for work, and my daughter had spent the night at a friend's house. My twelve year old son, Scott, was in his room listening to music. I decided that I should throw a load of laundry into the washer before I took a shower. As I was sorting the laundry, I noticed a pair of my son's underpants was coated in something crusty. I knew exactly what it was and let out an exasperated sigh. I decided to put an end to this right away. Underpants in hand, I walked over to Scott's room and knocked on the door. "Come in," he said. I opened his door and held out the offending underpants. "Scott, have you been masturbating into your underpants?" I asked. Scott turned a bright shade of red. "Mom!" he whined, "That's personal!" "I know that you are growing up and that you have sexual urges, but you really should not masturbate," I admonished him. Scott lowered his eyes guiltily. I continued. "Your sperm is too valuable to waste by jerking off into your underpants." He looked up, confused. "Your sperm is supposed to be for making babies. Instead of wasting your sperm by shooting it in your underpants, you should shoot it in a girl where it belongs. That way, it has a chance to make a baby, like it is supposed to." Scott's eyes grew wide with surprise. "You mean...?" he sputtered. "Here, let me show you what I mean," I said. I sat down next to him on his bed and started rubbing his cock through his shorts. "Mom, what are you doing?" he protested. "I need to show you what you are supposed to do with your sperm," I responded. I unzipped his pants and pulled down his pants and underpants with one motion. His cock was already starting to get hard. I bent over and took his preteen cock into my mouth. "Oh, Mom, that feels so good," Scottie groaned. His cock was now fully erect. At twelve, his cock was not as big as it would get as he continued to mature, but he was already five inches long and wide enough that he filled my mouth nicely. Feeling his cock twitch in my mouth was really turning me on. I knew that, with Scottie being a teenage boy, I could probably make him cum in my mouth very easily. But that wasn't what I had in mind. I reluctantly pulled my mouth off his young cock. I pulled my nightgown up over my head and threw it on the floor. Scottie was staring at my tits. I was probably the first real woman that he had seen naked. I told him to slide over on the bed and I lay down next to him. "Now, you can't just stick your cock in a girl and shoot your sperm into her. You need to make sure that she enjoys it, too," I said. "Give me your hand." I spread my legs and took his hand in mine. I put his hand between my legs and placed his finger on my clit. "Do you feel that bump?" I asked. Scott nodded his head, eyes wide. "That's my clit. Rub it gently." Scott did as I instructed. "Now, slide your finger up and down. Do you feel how wet I am down there? That's what happens when a woman gets sexually excited." "Now slide your finger a little lower. Right there. Slide your finger in that hole. That's Mommy's pussy. Oh, honey that feels really good." "Now I want you to do something else for me. You know how I sucked on your cock?" Scott nodded his head again. "You can do that to me, too. Just slide down so that you are between my legs. Now lick up and down my pussy. That's it. You can also lick back and forth on my clit, right here. Oh, right there...Oh, God, you are making Mommy feel really good." Reluctantly, I sat up and pulled away from his mouth. Breathing heavily, I told Scott to lie on his back. I took his cock in my hand and moved so that I was straddling him. I put his cock at the entrance to my pussy and lowered myself onto his erection. My pussy was so wet that I slid all the way down his cock until our crotches met. I was so turned on that I wanted to come badly, but I didn't want Scott to come until I had. I started slowly moving back and forth, grinding my clit against his pelvis. "Oh, Mom..." Scott groaned. "You feel so wet and hot. This feels great!" "You're making Mommy feel great, too. Pretty soon Mommy's going to cum on your cock." Before long, I felt my orgasm starting. "Oh God, Scottie, I'm going to cum. Ohhhhh...." I stiffened as my body exploded in an orgasm. It was a couple minutes before I came back down and remembered where I was and what I was doing. I glanced down at my son who was looking at me with a combination of awe and concern. "That felt great, honey," I reassured him. Now it was time to finish the lesson and show my son what he was supposed to do instead of jerking off into his underpants. "Let's switch places," I said. I rolled off my son and onto my back with my legs wide open. He positioned himself between my legs and I pointed his cock at the entrance to my sopping pussy. I let out a long groan as his cock slid effortlessly into my pussy. "OK, now slide your cock back and forth in my pussy. That's it," I panted. Being young, I knew that Scottie would not last very long. Sure enough, within a couple minutes, he was grunting as he slid his hard cock into and out of my pussy. "Oh, Mom, I'm going to do it soon. I'm about to cum." "Do it, Scottie. Cum in my pussy. Shoot your sperm into me so they can try to make a baby in me." "I'm going to do it. I'm coming, Mom. I am shooting my cum in your pussy. Oh...oh..." Scott thrust his cock all the way inside my pussy one last time as his whole body stiffened. Just knowing that my son was shooting his fertile sperm into me almost sent me over the edge of another orgasm. Scottie collapsed on top of me and we lay there for a few minutes, his head between my tits and his cock slowly wilting inside my pussy. After we had both had a chance to rest, I said "Now you know where your sperm is supposed to go, I don't want you jerking off into your underpants any more. When you feel like masturbating, I want you to shoot your sperm into me or your sister. Scott jerked his head up in surprise. He had a grimace on his face like he had just eaten a lemon. "Lizzie? But she's my sister. And she's so young." "Your sister is starting to grow up. She needs to learn about how to make a baby, too." "Well, ok," he said, still looking skeptical. ___________ A couple days later, I was washing dishes when my ten year-old daughter, Elizabeth (we call her Lizzie) came running into the kitchen. "Moooom," she screamed, "Scottie says he wants to put his thingy inside me. He says you told him he could." "That's right, Lizzie," I explained as I dried off my hands. "You and your brother are starting to grow up. You both need to learn how babies are made." "But, Mom..." she started to protest. I did not want to hear her objections. "Come on," I said, guiding her down the hallway into her brother's room. "Scott, Lizzie says that you told her that you wanted to have sex with her." "But Mom, you said..." "I know what I told you." I said, turning to his sister. "Lizzie, your brother needs to learn how a man makes a baby in a woman. You are starting to grow up, too. It's time that you learned how a man puts a baby in a woman's tummy." "But Mom," she protested, "I already know all that." "You do? How?" I asked. "My friend Sara's older sister has a book that her parents gave her. It talks about sex and how a girl gets pregnant." "So tell me what you know," I told her. "Well, a man puts his thingy in a woman and something called `sperm' comes out. If the time is right, it makes her pregnant." "Show me," I ordered. "What?" she asked, surprised. "Since you know so much about sex, show me what you know." Well, I..." she stammered. "So you don't really know that much, do you?" "I guess not," she said, hanging her head. "Ok, now that we have that settled, let's get started. You both need to be naked, so take off your clothes," I instructed. Scottie was more than happy to comply and had his clothes of and was back sitting on his bed in no time. Lizzie was more reticent. She looked at me skeptically. I gave her a curt nod. She turned so that she was partially turned away from us and started to remove her clothes. Once Lizzie had removed all of her clothes, she turned back to face us. Even though I had tried to raise my daughter not to be ashamed of her body, she was clearly a little embarrassed to be standing naked in front of her mother and brother. It had been quite a while since I had seen my daughter naked. She had shoulder length chestnut-colored hair. Her breasts were little mounds, just starting to grow. Her tummy was perfectly flat and she didn't yet have any real hips or waist. She was standing with her legs together, so I could just see the top of her slit. There was no trace of hair on her pubic mound. I felt proud when I thought of how beautiful my daughter was becoming. "Scott, get out of the way so that your sister can get on the bed." I instructed. "Lizzie, get on Scottie's bed and lie down. Come on. Open your legs. That's it." "Scott. Do you remember what I showed you about making the girl feel good?" I asked. He nodded, his eyes glued on his sister's bald pussy. "OK, let's see what you remember." My son crawled between his sister's legs and bent down to start licking. "What's Scottie doing to me, Mom? Oh, it tickles a little...." Lizzie squealed. A minute later, she groaned. "That feels sooo good, Scottie. Ohhh..." I let Scottie lick has sister for about five minutes. By this time, she was breathing pretty hard. I could see that he was excited, too, and his cock was rock-hard. "OK, Scottie, it's time to show your sister how your cock goes inside of her and puts your sperm in her." Scott lifted himself up until he was over his sister, with his cock pointing at her bald, pussy. "Lizzie, spread your legs nice and wide for your brother. It will probably hurt a little at first." "I know, Mom," she said. "Scott, you need to push your cock into her pussy, but try to be gentle. You sister is little and a girl's first time usually hurts." Scottie made several attempts to get his cock into his sister's tight pussy, but he would get the tip in and then he would pop back out when he tried to push into her. Finally, Lizzie decided to help move things along. She put her hand on her brother's cock to hold it in place. Then she put her hand behind him and pushed up while he pushed his hips down towards her. Scott's cock pushed through his sister's hymen and slid down into her pussy. "Owwww..." Lizzie let out a wail. Scott scrambled to get off his sister. "No, stay there," I ordered. "She'll be alright in a minute...OK, go slowly." Scott started slowly moving in and out of his sister's pussy. "It still hurts, Mom," Lizzie whined. I dismissed her complaint. "It will get better. Keep going." Although he was trying to go slowly for his sister's sake, before too long Scottie's instincts began to take over and he started to increase the speed of his thrusting. Soon, Lizzie stopped wincing every time her brother pushed his cock back into her and her breathing became ragged. I cannot describe how erotic it was to watch the two of them having sex. Lizzie's bald little pussy looked so hot stretched around her brother's cock. I was getting really turned on watching them. I really wanted to touch myself, but I knew that I needed to pay attention to what they were doing. Within a couple of minutes, Scott started grunting with each thrust into his sister's pussy. I knew that it wouldn't be much longer. "Pretty soon Scottie is going to cum," I said to Lizzie. When he does, sperm will come out of his cock and spray into your pussy...Go on, Scott. Squirt your sperm into your little sister. Show her how a man puts his sperm in a woman to make a baby." Scott's groans became louder. "I'm going to do it. I'm going to cum soon." "That's it. Put your sperm inside your sister so she knows what it's like." "Yeah, Scottie. Do it. Put your sperm in me. Show me how you make a baby inside me." "Ohhhh...." Scott thrust his cock into his sister's pussy one last time and his body tensed as he froze in that position. "He's doing it," I said. "Your brother is shooting his sperm inside your pussy." "Put your sperm in me, Scottie," Lizzie urged again. Watching my son shoot his sperm into his little sister almost made me come myself. After a minute, Scott collapsed, laying himself a little to Lizzie's side so that he wouldn't squash his smaller sister. His cock stayed firmly planted in her bald, preteen pussy. "See, Lizzie," I said. "Now you know how a man puts his sperm in a woman's body to make a baby in her. Scott is young and will feel like he needs to put his sperm in a woman's pussy a lot. I told him that he can put his sperm in my pussy whenever he wants to. I want you to let him put his sperm in your pussy if he wants to." "OK, Mom," she replied. I continued. "And I want you to tell me if you notice any blood on your panties or nightgown." "You mean my period?" she asked. "I already started having them." "How do you know about having periods?" I asked. "Sara's sister's book talked about having periods, too, so I knew what it was when it happened. I just used one of your pads." "When did you start having them?" "About two months ago." Uh-oh. "When was your last period?" I asked nervously. "I dunno. A couple weeks ago, maybe a little more." Suddenly, I had a vision of an egg floating in my ten-year old daughter's fertile womb as her brother's young, vigorous sperm swam frantically to try to fertilize it, impregnating the young girl. As that vision filled my mind, all of the sexual tension in my body released, wracking my body in an immense orgasm.
