Title: Jack's A Good Kid, Part 1 Keywords: ped, inc, mg, cons, creampie Me and my wife Joanne were sitting at the dinner table. We could hear the bed squeaking upstairs. "Do you think they..." I started, but couldn't finish. "Yeah," my wife grunted. I guess it was no wonder. They didn't need to hide it any more. That is, my son Jack and my daughter Alice. Jack's seventeen. A good son in all respects. Doing great at school, works hard in his part-time job, just an all-around good kid. So last week when I walked in on him rutting into his tight four-year-old sister, what was I to do? I couldn't call the cops on my own son, especially since I knew Jack's a good kid. Alice wasn't in tears, and didn't even look like she was hurting. If anything, I was a little envious of the boy for doing something I myself had not dared to do. I mean obviously it has been in my mind, just as it would be in any father's mind when he has such a little cocktease of a daughter. After all, Alice was a gorgeous little girl: brown hair still on its way to growing fully out, big brown eyes, heart-melting smile and a round little butt that would send any guy's cock into hardness. "You think we should do something?" Joanne asked, looking at me. That broke me off my thoughts. "He's not hurting her," I said sheepishly. We listened for a moment to the squeaking of the bed. Jack's a good kid, was all I could think. After breaking up with his second girlfriend last year, we hadn't seen him with another girl in a long time. It made perfect sense now. Jack had actually started to work on little Alice then. He'd been fed up, and I couldn't blame the boy. He was a popular guy - handsome yet smart, athletic and bound for success, seemingly. But both his girlfriends had cheated on him, so he just renounced trying to date girls, and it kind of made sense to me, even though I wouldn't admit it to Joanne. Girls his age just can't stay loyal. Yet if he's anything like I was at his age, he'll need his nuts emptied constantly. After dating two beautiful girls, there was no going back to jerking off for him. In a sense it seemed only natural for him to start getting involved with his four-year-old sister. Of course, we'd been completely oblivious to this when it started. We only noticed the two spending a lot more time together and being much more close. Me and Joanne just thought it was beautiful and cute. It was that, but what we didn't know was that Jack had started rubbing his teenage cock on the girl's bald, fat little cunt. Jack admitted everything to me last week after I caught them in the act. He told me the whole story. In the beginning it had been enough for him to just rub his cock on Alice's little cunny, and then have her suck the cockhead while he jerked off into her mouth. Jack had taught her right away to suck on his cock and swallow, and Alice apparently saw it just as a fun game that ended in him shooting something funny-tasting into her mouth. Jack said to me it had only made sense for him to cum inside Alice's mouth, since that way there was no mess needing to be cleaned up. But as the weeks went on, he wanted badly to actually fuck, not just deposit his cum inside his sister. So he had tried it some months ago. Alice was only three years old at the time, and Jack had to stop with just a little bit of his cock in, as soon as Alice started hurting. Jack kept telling me he stopped as soon as Alice told him it hurt, but she bled a little bit anyway. I told you, he is a good kid and wouldn't ever want to harm his sister. Alice had not wanted to stop, he said, and liked the play they had together, so Jack simply included stretching of her young cunny in their doctor games. Every day they played doctor, and every day Jack gave "treatment" for his little sister for her "tight cunny." A few months ago it finally started to bear fruit, and Jack started fucking her gently, with just shallow strokes. Now Alice could take most of him in. Jack can't fuck her hard, but it still looks very much like two animals mating when they go at it - though, of course, two animals of distinctly different sizes. But I must say, as shocked as I was to discover my seventeen-year-old son rutting his four-year-old little sister, it also stiffened my cock very very hard. I found myself smiling thinking of my reaction. I had been stunned, just looking at Jack with my jaw dropped for a few seconds, with the boy glancing over his shoulder, but unable to stop doing his sister in doggie. The hip movement into your little sister must be so instinctive. He looked worried how I'd react, but I just stepped back and let them continue in peace, after having made sure Alice wasn't hurting. Of course me and Joanne had a long talk with Jack after that. The boy didn't seem to regret what he had done, and we weren't too angry either. If anything, I was upset that he would do something like that behind our back. I didn't know if I condoned it, but I couldn't forbid it, because I didn't want Alice to develop some psychological complexes thinking that something wrong had been done to her. For clearly Alice liked bonding with her brother like that. So we didn't outright tell Jack to stop, we just told him to not hurt his sister. So we come to this moment. I'm sure they've fucked in between, but now the squeaking bed just made it very obvious for us. Joanne was still looking at me intently. "I think we should go make sure he isn't," she said. I raised my eyebrow, looking at my wife surprised. If I didn't know better, I would have said she was curious to see it for herself, and in a deviously deviant way. To be honest, I didn't even know better. "You wanna see it?" I asked, with a hint of smile coming to my face. Joanne diverted her eyes. "Well, I just think it'd be fair for me to see it, given you've already seen what it looks like," she said, and it sounded like an excuse. "Besides, only another woman could really tell if she's hurting or not." I just nodded, but I did wonder about her motives. I couldn't put my finger on it, but I could swear the idea was arousing her. You know, it's just the way you learn to read someone you've been married to nearly two decades. Anyway, I didn't stop to question her, since I wanted to go watch as much as she did. Any excuse to go do that was good enough. As we walked up the stairs the squeaking got louder. With my wife's hand in mine as I led her to the room, I could feel the tension in her. She couldn't imagine what it would look like to see her children with thirteen years of age difference fucking together. Soon she would see. I opened the door. At moments like this I'm glad I never had locks put in the doors to the kids' rooms. I can just walk in. Again Jack glanced over his shoulder, surprised to see us, but unable to stop fucking. He was between his little sister's legs, with her little body barely visible under him, cock obscenely stretching the little cunny, a few inches of it kept outside Alice's cunt that couldn't take all of her brother's big cock. All I could think of was to feel that tightness around me. I was envious of my son. Then again, I'm even bigger than him, so I was glad it was him that fucked Alice, since I might have hurt her. "Umm, what's going on?" Jack asked. "Don't mind us, son. Your mother just wanted to have a look to make sure Alice is enjoying herself." "... Alright," Jack said, turning back to look in the eyes of the tiny girl underneath him, and slightly intensifying his thrusting. Joanne was squeezing my hand slightly harder. I think it was subconscious. Her eyes were wide, amazed, and completely focused - almost entranced by the pistoning movement of her son's hips between Alice's legs. I turned to her, smiling. "So, what do you think?" "I... I... I think I gotta have a closer look." Now there was no doubt in my mind. Joanne was getting off on this. I had never seen a face like that on her, but I could sense her arousal. I knew I wouldn't need any foreplay with her after this to get my nuts off. I let go of her hand as she ventured deeper into the room, and I took the liberty to go look closer as well. As we approached the incestous couple, the smell of sex was in the air, the sweet smell of four-year-old pussy. It sent an instinctive reaction down my body to fill my cock with blood. A better look at my handsome son fucking his beautiful sister worked to accelerate that process. Jack didn't seem to mind me and Joanne watching in the end at all. If anything, he embraced it. "Let's give Mommy and Daddy a good show, Alice?" "Okay, Jack," Alice smiled. Jack hunched over to kiss her while still rutting her. I could see they were sharing full, open-mouth kisses with plenty of tongue, so sloppy I almost blushed myself. Then again, it would be hard to blush at this point any more, given the boy's cock was already pounding against her little cervix, and I was witnessing their nude bodies tangling together. Alice wasn't put off by the fucking at all, and her short little limbs were trying their best to wrap around Jack's body, and just about managing it. I wanted to whip my cock out and start jerking off to this sight. I glanced at Joanne. She was breathing heavily. I could tell she had similar thoughts. I was surprised she was so into this. We had never talked about topics like this. Could she have been into incest all along? "Fuck, I think I'm gonna cum soon," Jack said, and pulled his head away from his sister's mouth. He straightened himself with an intent gaze on his face, hips still moving in and out. Little Alice was looking down between her legs, seeing her puffy pussylips stretched by the repeated strokes of her brother's cock. "Yes, son, creampie your little sister," Joanne suddenly said. It was a sound heavy with arousal, killing any doubt I might have had over her being into this. She was fucking horny as hell! "Creampie?" Jack asked his mother, surprised, still unable to stop fucking while talking to her. "I normally pull out and finish off inside Alice's mouth. Less of a mess that way. I've never creampied her." "Then it's about time you do it!" Joanne demanded. "I'm here to make sure she enjoys it, after all, and I know how us girls like to get a nice creampie." She placed her hands on Jack's bare asscheeks, squeezing repeatedly with every push inside Alice's tight dreamcunt. I have to admit, it aroused me even further seeing Joanne's hands on our son's bare butt. "Don't you dare to pull out," she added into our son's ear, determined to push him back in if he tried anything. Jack's a good kid though. He'd never disobey his mother. His face turned strained and he let out a gasp. "Fuck, here it comes, Alice, your first creampie!" he moaned, and his hips instinctively pushed his cock as deep inside as it would go. All his hips knew was they were trying to breed the female his cock was in. It was only instinctive and I knew Jack couldn't help it. The hard push against Alice's cervix made her whimper a little. Jack groaned loud. It was such a turn on to see my son's body jerk between his four-year-old sister's legs, over her tiny body, as his balls emptied the potent payload of incestous cum inside his little sister. I knew it was potent, because Jack's first girlfriend had to have an abortion after she got preggo when a condom broke just once. Now Jack wouldn't need a condom, not for years anyway. My wife took a couple steps back and I grabbed her. "John, take me away from here before I do something I'm going to regret," she whispered to me. I could feel the heavy arousal overflowing from her. Jack murmured one final time as his balls emptied the last drops inside his sister. "Sis, I love you," I could hear him telling Alice as I was already dragging my wife out of the room, with a plan to fuck her brains out and get both of our nuts off, thinking of the obscenity we had just seen between our children. "I love you too," Alice said softly as she squeezed her big brother. They cuddled as me and Joanne exited the room, Jack's wilting teenage cock still inside his sister's undeveloped little pussy. I entered our bedroom with Joanne, forced my hand down her panties and found a drizzling wet pussy. I tried to think back to an instance in our long and sex-filled relationship when it had been that wet, but failed. In any case, our mouths locked together, tongues entangled and soon I was between my wife's legs, rutting away as hard as my son had been with his sister mere moments ago - of course with Joanne being able to take my big cock all the way, even with hard strokes.
