I knew Lisa was fucking around with somebody! Somebody was surely about to ruin her life, leading her down a road to disaster. I was determined to find out who it was, and put a stop to it, quick.
In case you don’t know me, my name’s Lynda. I’m a forty-two year old redhead; I’m proud that I still have a sexy body and sometimes I like to dress up so I can turn heads with my 36C figure. Lisa, my stepdaughter, adopted at the age of four when her own parents were lost in a car accident, just turned eighteen a couple of months ago. Though she has known since she was twelve that she’s not our blood relative at all, we have spent the last fourteen years developing as strong a bond as any mom and daughter ever could. I married my second husband, Jack, about a year ago, and for a while everything seemed really wonderful about everyone in Jack’s family.
Everyone, that is, except his good-for-nothing brother, Bill. Not that I minded that Bill has spent his whole life as a truck driver – I didn’t mind that at all. But I knew what kind of life he led out there on the road. With all the questionable women that I knew Bill must have taken up with over the years, I didn’t want to have anything to do with him. And I sure as hell didn’t want him anywhere near Lisa! A few weeks ago, I started having suspicions. Right after her eighteenth birthday, Lisa spent the entire afternoon hanging around with her uncle Bill. Ever since then, I knew something was going on, much more than what she told me. “All I did was go for a ride with uncle Bill in his truck,” she said. But I saw that look in Lisa’s eye. I was a horny teenage girl myself at one time, and I knew all the signs. Like I said earlier, I knew she was fucking somebody. As unthinkable as it was, I was convinced it was my perverted brother-in-law, Bill. But I knew nobody would believe me if I accused him; I knew Bill and Lisa would both deny it if confronted. But I also knew my husband Jack would kill him if he found out, and I was determined to get proof. I began to listen carefully to the little lies and half-truths Lisa was telling me, and a few days ago I knew I had the chance to finally catch them in the act. Lisa told me that she’d be going to the movies right after school with a friend and wouldn’t be home for a few hours; but she mentioned her movie plans on two different occasions, each time mentioning different movies and different friends. I knew her real plan for the day was to have a rendezvous with her uncle Bill – and at our house, no less! Lisa and Bill both knew that Jack and I never arrived home from work before 7:00. Since Bill always stayed over at our place when he was in town, during breaks from his road schedule, I was sure that this time he’d be coming in to meet up with Lisa. She was obviously lying about going to the movies, so I was sure that I knew their secret plan. From 3:00 to 7:00, she and Bill would have the house to themselves. I left work at 3:00, heading straight home and doing my best to sneak into the house unobserved. Just what I suspected, I thought to myself, seeing the cab of Bill’s truck parked in the street, and seeing Lisa’s car in the driveway. She had obviously come straight home after school and was in the house with Bill, alone. I was afraid that even if I discovered these two fooling around, my husband might not believe my accusations. You know the saying about blood being thicker than water. But there was nothing I could do about that right now. I would catch them in the act and worry later about convincing Jack that his no-good brother could stoop so low. There was no mistaking the sounds I was hearing – and they were coming from the master bedroom. Bill was fucking Lisa, and doing it in my own bed! As I rounded the corner, I could see that the bedroom door was open just enough for me to see without being seen. And oh my god, what a sight! There was Lisa, flat on her back on my own bed, her skirt hiked up, legs spread wide. Her panties had been tossed onto the floor beside the bed. Bill, his back to me, was leaning over her, still fully clothed. He was eating Lisa’s smooth young pussy in a way that was obviously sending her to heaven. Her fingernails were digging into the blankets as she humped his face and squirmed ecstatically. I couldn’t believe what I was seeing as he brought Lisa off to a screaming orgasm. I knew I should have stormed in and stopped it right then. But I was curious – how far had things gone between these two? What else had her uncle Bill been doing to Lisa? And what had she been doing to him – and with him? I decided to wait, and watch. I was so angry, I could feel myself getting hot. I was spellbound as Lisa helped Bill undress. I had always thought of him as sort of a low-class, rough sort of character. But as Lisa stripped away his shirt and started to unzip his jeans, I started to realize that maybe it wasn’t anger that was causing me to blush. My emotions began to confuse and overwhelm me. I kept debating with myself even as I kept staring at them. Was I embarrassed to see them doing these slutty things? Was I ashamed and outraged that they were family? All these thoughts raced through my mind as I saw Bill standing there, stripped naked by Lisa. She was on her knees, gently cupping and squeezing his balls, her hand wrapped around the nicely swollen shaft of his cock. And as I watched her lovingly licking that mushroom head, sucking on it and opening her little mouth to let him slide his cock past her lips, I suddenly knew what was bothering me. I felt the heat rise in my neck and my face grew flushed. My heart began to race as the realization hit me: I was jealous! I loved what was happening and wished it could be me in there, instead of her! Bill’s body looked so strong; his rough-looking muscles and tanned arms looked so amazing as Lisa’s little hands roamed across his body. I kept trying to convince myself that my jealousy couldn’t be real. I should be outraged! But I was no longer angry; I was fascinated, spellbound, and definitely becoming intensely aroused. I gulped as I saw Bill’s big strong hands pulling at the buttons of Lisa’s blouse. She reached back to unhook her bra; Bill pulled him to her as her clothes fell away, and sucked hungrily at Lisa’s nice full tits. My own nipples were rock hard at this point, just like hers. I could feel them poking through my sheer bra and rubbing against my silk blouse. My whole body was trembling, and my hand reached under my skirt to rub my pussy mound through my panties. I saw Lisa pulling and stroking Bill’s cock as he nibbled lovingly at her breasts. His cock had gotten so fucking big and fully hard by now. I almost gasped aloud as he grabbed the elastic waistband of her skirt and gave a sharp pull. Oh my god, Bill was sucking Lisa’s tits and fondling her naked ass! She giggled and fell back onto the bed – my bed! In no time at all she was getting one hell of a good fuck from Bill. Lisa had already cum once with Bill’s face buried in her pussy. It was obvious that she was going to cum again really soon. But I decided that there was no reason to wait for Bill to do likewise. I collected my thoughts and stopped rubbing my pussy, which by now had completely soaked through panties. My feelings of jealousy returned when I saw how Bill devoted so much care to getting Lisa off as he fucked her. And Lisa’s cries left nothing to the imagination. She was begging to be fucked, hard and deep, and obviously experienced a mind-blowing orgasm with Bill’s hard cock buried to the balls inside her. I took a deep breath and stormed into the bedroom, doing my best to look angry, not excited. Lisa, flat on her back with Bill’s dick still inside her, screamed “Mom!!” almost at the same instant that Bill yelled, “Holy shit – Lynda!” For a few seconds, I stayed silent as I gave Lisa the time to cover herself with the nearest sheet. Curiously, Bill made no attempt to cover himself; his lack of concern was infuriating! It was time for a talk. I don’t even remember now what I said, but I was trying to give the “angry and outraged mom” lecture. But soon I realized that as I was talking, I was just staring at Bill’s cock, still jutting out hard and throbbing. I couldn’t help notice that it was shiny and wet, covered with the slippery wetness from that tight little pussy. The thought of that made my own pussy ache and gush even more. “Lisa,” I said, “you’d better get out – I need to speak to your uncle Bill alone.” Lisa ran down the hall to her room. “Bill,” I said, “you can’t have Lisa. You’re twice her age, and she’s your niece, goddamit!” I kept getting the impression that Bill was trying to interrupt me, but I kept cutting him off, trying to stay angry and stare at his throbbing dick at the same time. That amazing cock seemed to be getting even harder as I stared at it. Unaware that I was doing it, I stopped talking for a second and licked my lips, still staring at his pulsating erection. “Lynda, please, let me tell you something,” he said as he walked toward me. I stepped back, not wanting him to notice how breathless I was. I backed up and unexpectedly hit the edge of the bed, losing my balance. I fell back into a sitting position on the edge of the bed as Bill walked right over in front of me. My mouth was open and I was having a hard time breathing. Bill’s huge cock was bobbing six inches from my face. I licked my lips again, gulping. “Lisa and I have been fooling around, it’s true,” he continued, “but Lisa was the one who went after me, that day she went riding in my truck. It wasn’t my idea, it was hers! I’m sorry you found out, but today was the last time, we’ve already both agreed that it was just for fun, and we won’t be doing it any more!” He looked down and smiled, my skirt had slid well up on my thighs as I had tumbled back onto the bed. Bill could see that my panties were totally soaked. “You…you won’t be getting together with Lisa?” I stammered weakly. Bill smiled again, his eyes looking up and down, shamelessly checking out my wet pussy and the hard nipples poking through the smooth silk of my blouse. “No, Lynda,” he said, “I think she wanted to learn a thing or two, but she knows that the best thing for a man like me is to have a woman my own age…” his voice trailed off as he reached forward and slipped two fingers inside the neckline of my blouse, just above my cleavage.
