I was home alone, and expected to remain that way for a while. The girls were out and I didn't expect either my eldest, Joan, or her younger sister Louise home before the wee hours. Karen, my youngest, hadn't started dating regularly yet, so I did expect her home, but I've learned that when she says nine o'clock she means midnight. I was surprised, then, when Karen came in. She was lugging a big pile of books and it was obvious she had been at the library again. She nodded to me and wandered back to her room after dropping her books on the coffee table. Karen was a bit silent, but that didn't concern me. She was a moody girl at the best of times. She was just fifteen now, and going through a lot. Fifteen is a tough time for any girl and Karen was no exception. She was just beginning to date, sex was the most important thing in her life and she hadn't quite figured it out yet. After a few minutes Karen came out of her room carrying a basket of laundry. As she dropped her things in the kitchenette and began loading the washer I asked her if she was going out and needed clothes. She said no she didn't she was just out of clothes for tomorrow. I went back to watching TV while she loaded the washer. I heard the lid close and glanced her way. I saw her hesitate, then lift the lid again. She pulled off her shirt and dropped it inside, then did the same with her socks and jeans. She started the washer, then wandered into the living room in her shorts to get a book. While she was there I asked her what she was reading. She told me, Oh, just the same old shit, and flopped down on the sofa opposite me to read. It's a little unusual for Karen to run around in her shorts. She's the shy one of my three girls. Joan is into weights and you can hardly keep clothes on her. Louise is seventeen, and beginning to fill out, so she is proud of her body and doesn't wear a shirt if she doesn't have to. Karen, is still in that gawky, gangling stage that tall girls go through and doesn't undress much in front of anyone else. In fact, as I thought of this, I looked her over and realized that it had been more than a year since I had seen her in so little clothing. She lay on her side, facing me, with the book on the cushion in front of her. Her left arm supported her head, and her right she draped over the back of the sofa. I took the opportunity to look at her carefully. Karen is tall for fifteen, a full five feet nine inches. She is as tall as I am, and absolutely towers over her sister Louise. Lying on the sofa, taking up it's full length and ten some, she looked even more slender than she is. Her shoulders are still narrow, and haven't begun to fill out. I followed the "S" curve of her body, across her ribs to her narrow waist, and back up the curve of her hip. He skin was stretched tight over her ribs and she looked skinny. When I looked more closely, I could tell, thought that she was not. Her chest was not big, but was well formed, with small, pink nipples that seemed to be erect all the time. Another "S" curve ran down the centerline of her chest and ended at her navel. It was a clear line of separation between the muscles of her abdomen. I looked closely, but still could see no hair on her body. Young as she was, I couldn't help notice that she filled her shorts pretty well. Maybe that runs in the family too. Karen looked up from her reading, feeling my eyes on her, I suppose. She asked me, Something wrong? and I told her no, just looking at my girl. She sat up and looked at me and asked me if we could talk. Karen and I have always been close and they way she asked, it was obvious that it wasn't just seeing me looking her over that made her want to talk. I moved to her side, and took over one end of the sofa. She scrunched up next to me and I put my arm around her shoulders. She leaned back against me and looked up and said Daddy, I've got a problem. I knew that it was a serious one when she called me Daddy. The other girls had stopped that years ago, and even karen, who had hung on for ages, had stopped by the time she was twelve or so. Karen told me about a terrible experience she had only a few days ago. She and Richard, a boy in her history class, had wound up necking. He, not she, made some moves and she found herself on the verge of losing her virginity. They went back to her car and she found herself either unable or unwilling to go through with it. Karen was so upset, it was breaking my heart. I put my arms around her and pulled her close. She looked up at me, her dark eyes moist and ready to tear. I hugged her closer and told her not to worry. She really did cry then, and stammered out that she was upset because she had wanted to do it with Rich. There was really nothing to say at that point. I just held her close and told her everything was ok. It was then that she surprised me. She said to me, Joan is gay, isn't she? I thought my eldest had hidden the fact well, but I guess you can't keep anything from family. I told Karen, yes, she was, and I was sure she was happy about it. If you are gay too, I told her, it won't make any difference to your family. She surprised me again. She said to me, well, Joan told me that you had...well. I looked at her and told her, yes I had, Joan and I had made love. Under the circumstances I knew what was going to happen, and I wondered if Karen did too. It occurred to me that her being in her underwear was not an accident, but I shook that aside and paid attention to my girl. She was hurting. I pulled her closer, and she stammered out what she wanted... she wanted me to be her first. I could say nothing, except to say yes. I lay Karen on her back with her head resting in my lap. With my left hand I smoothed back her hair. I rested my right hand in the middle of her chest, and felt her warm skin against my palm. I thought about what was going to happen. Karen is such a handsome girl, and as I slid my hand across her chest and over the smooth skin and hard muscle of her belly I thought about how badly I wanted her. She looked up at me, her head in my lap and I leaned forward to cup her breast and gently squeeze. She turned toward me and raised a hand to my chest. As she loosened buttons I stroked her ass through her pink cotton shorts. I slipped my fingertip under the edge of her shorts and tickled the curve of her ass. She wriggled and looked up at me again. I moved my hand to her chest and began to tweak her nipples. Without finishing my shirt buttons she reached down and began to wrestle with my zipper. I stopped her, and pushed her onto her back again. I didn't want things to go too fast. If this was going to be Karen's first time I was damn well going to make sure that it was going to be hot. I wanted Karen to wriggle and writhe and beg to cum. I put an arm under her shoulders and lifted Karen up until her head rested on the arm of the sofa and her crotch was within easy reach. Leaning forward I pulled her up with one hand until I could put my mouth over her nipple. I sucked and while I did I used my tongue to tease her. With my other hand I squeezed her crotch, first her cunt then the shaft of her stone-hard clit. I was amazed at it's size. For a fifteen-year-old, Karen was damn well developed. I'm pretty big, over eight inches, and wondered if I'd hurt her. While I squeezed her cunt through the light fabric, she pulled at her shorts. I released her briefly, moving my mouth to her while she curled up her legs and flipped her shorts away. She sat up facing me and while we kissed she curled her legs underneath her and I kicked off my shoes. She went back to unbuttoning my buttons and I grabbed her ass with one hand while stroking her cunt with the other. With my shirt finally open, she leaned forward and ran her lips across my chest. She stopped to suck hard on my nipple while I grasped both of her between thumb and forefinger and squeezed hard. While continuing to suck she fumbled again at my zipper and this time I let her get it open. She reached for me, but my jeans were just too tight. I pushed her back and she bit gently at my nipple as I pushed her away. When I stood, so did she, and as I pulled off my jeans and shorts I took time to look at her again. Karen stood there looking at me with her arms crossed over her chest. Doing this emphasized the curve of her tits and made me think again about the fact that her small nipples seemed always erect. I looked her in the eye and she tilted her head to one side and smiled. White teeth flashed from behind full lips. Karen has a beautiful smile. Her blond hair is about collar length and frames her long face nicely. There is a roundness to her face that seems boyish and is not offset, somehow, by her long jaw. Of course, those wide-set, moist-looking brown eyes are real killers. I remembered that I had always looked at her as an infant and thought of those tacky paintings of big-eyed waifs. She rested her weight on one foot and it gave her hips a sexy slant. As my eyes traveled down her hard, slender body they settled on her cunt. Her pussy lips appeared to pout through her light pubic hair. I could hardly keep my hands off. In fact, I didn't. I reached over and took her cunt in my fist and used it like a handle to pull her to me. I pressed my mouth against her and moved my hands around to her ass. I gripped both cheeks and dug my fingers in to press her crotch against me while my tongue prodded and fenced with her. After an endless time I came back to myself and realized that I was gripping Karen so powerfully that I had nearly lifted her off her feet. She had one hand around my neck, pulling my head forward and the other on my ass, squeezing for all she was worth. Breaking from that embrace took all my will-power, but I did it. I sat back down, and put my arms across the back of the sofa and just looked at her. Standing there, nervous, and not knowing what to do with her hands, she just looked back at me and grinned. I leaned forward and once again burried my face in her belly. Re-settling myself on the sofa I began to tease her cunthead with my tongue. She just stood there for a moment not knowing what to do then put her hands behind my head and tried to feed me more of her cunt. I didn't let her. I wanted to tease her for as long as it was possible to make a first time last. I continued to tease her slit and just the head of her cunt with my tongue and I began to stroke the backs of her thighs. I was amazed at how smooth the skin was. Karen has very fine hair on her legs, but it is so soft as to be forgotten. Karen began to thrust toward my mouth again, and this time, to prevent her, I had to stop. I sat back on the sofa and I pulled her down on my lap. She wound up kneeling with her knees beside my hips and our genitalia pressed close together. With my right hand I grabbed my cock and began to stroke it. At the same time I reached up to pinch her right nipple between my left thumb and forefinger. I pushed her slightly backward and with a bit of a stretch I could suck her other nipple. Sucking hard, pinching hard and stroking with long slow strokes I could have stayed that way for hours. Karen was into it too, she began to pump her crotch toward mine, matching my strokes, and I began to long to have my fingers dug into her cheeks, feeling the squeeze of her ass muscles as she thrust toward me. I couldn't take it any longer, and I think Karen was about to explode too, when I decided it was time to get this girl's cunt down my throat. I reached behind her and gripped her cheeks. Pulling her upward, I repositioned Karen so that her knees rested on the back of the sofa and her cunt was right in front of my face. I pushed my face forward and began to lick her all over. I did her clit first. As I licked her crotch she began to hump her cunt toward me. I reached up and pulled it down to my mouth. Taking her slowly was hard, but I made it last. I worked just on the clit for a few seconds, as I had done before, then I took part of the shaft and began to lick the underside, massaging with my tongue while I sucked. I took more of her into my mouth, and when I looked up, she had moved her hands to her chest and was stroking her nipples. My hands on both her cheeks I pulled her toward me and took her whole cunt in my mouth. Sucking as hard as I could I began to move my head back and forth, licking up and down the full length of her cunt, stroking her with my lips. I eased my hand around under her ass, and began to tease her asshole with my finger. She felt me tickle her asshole and shivered all over. Her thrusting against my face also began to be thrusts backward toward my finger. Gently I let just the tip of my finger penetrate, and Karen gasped. I took that moment to pull back and surround just her cunthead with my lips. I sucked hard and furiously tongued the slit. With a quiet moan she shoved her ass hard against my finger, getting an extra inch for her trouble, then she leaned forward against my face and delivered a load of cum onto my tongue. She shot again and again and I sucked her full length back into my mouth. She still had hold of her nipples, but she was now leaning forward, humping against my sucking mouth. I began to thrust my finger in and out rapidly of her ass, and she had to move her hands to the back of the sofa to keep her grip. As her cunt juices filled my mouth I thrust my finger deeper and she gave me a last squirt of cum. I moved my hands to support her ass and began to lower her back to kneeling position. When she was seated on my lap again, she sat up for a minute, and grabbing my cunt, pushed it under her. She sat back down, pressing my hard cock between her ass and my leg. I wiggled around a bit and it lined up neatly with the crack of her ass. When it did, she leaned forward and just as she kissed me she asked, are you going to fuck me, Daddy? Well I didn't much care to be called daddy just then, but I told her that I damn well was going to fuck her and she'd better get ready. Before I could make good on my promise, she slid back to the floor, and kneeling between my thighs, began to lick my crotch the way I had licked her. Karen knelt, leaning forward, her blond hair obscuring her eyes as she looked up at me, and began to suck my cock. Karen may have been a virgin that night, but she sucked me off like she'd had some practice. She started with me just as I had with her, sucking the head of my cock and teasing the slit. In moments she was taking the whole length of my eight-incher down her young throat. I don't think I could've managed one that big on my first try, but maybe Karen is a natural talent. In no time at all she was bobbing up and down on my prick like a pro, and sucking for all she was worth. I locked down at her back, seeing the "V" of hard muscle flexing as she moved, and let my hands rover over her shoulder blades. She kept wiggling that round, sweet ass as she bobbed up and down, too, and I decided that I damn well WAS going to fuck the girl no matter what. I hadn't intended to at first, thinking that would be better left for when she had more experience. Well, in no time I delivered a big load to the back of Karen's throat. She looked up at me and grinned, and said, well, I guess you won't be able to fuck me for a while, now will you? I stood up and let her see that my cock was still erect, though not as hard as it had been, and she looked up at me sort of thoughtfully. I reached forward, and picked her up. Carrying her in my arms I took her to my room and lay her on my bed. Seeing her lying there I couldn't resist and I leaned forward to suck her nipples for an instant, and her cunt for a brief moment. I pulled away, and picked her up again. I set her on her feet, and made her lean over the bed, supporting herself on her hands. I pulled out a tube of KY and began to lube her up. With each probe of my finger into her cunt, Karen wiggled and looked over her shoulder at me. I pressed my finger into her and she gave me that big white grin full of teeth. Now I stood behind her and pressed the head of my cock against her. She pushed back against me, eager to feel it in her cunt. When I began to press my cock inside her, however, it hurt her too much. She pulled away, and couldn't take it. I tried to be gently, and to work her up with my fingers first, but I was just too big for her thight pussy. Karen rolled over and seemed terribly disappointed. She said why didn't we go back to the sofa for a repeat performance and I agreed that it was a good idea. I sat back down and she sat on my lap facing me as before. I pressed my cock down under her where she could feel it slide up and down in the crack of her cunt then I pushed her back gently and began to work her nipples with my tongue. While I sucked her, stroked her cunt with my cock and stroked her ass with my hand, she reached down and gripped my nipples. Sitting there, thrusting my cock against her cunt, sucking and stroking, I could have been happy for hours. Karen was to young to be patient, though. She climbed back up on the back of the sofa and pressed her cunt against my face again. As I took the head of her cunt into my mouth, though, I got an idea. I stopped sucking her, and lowered her slowly toward my cock instead. I positioned us so that she could lower herself onto me, and she took over. While she bounced up and down, gently working my cock into her cunt in small steps, I reached up and got hold of her chest. I rubbed my palms up and down her body, tickling her ribs slightly while she worked to accommodate my cock up her cunt. Slowly, Karen settled herself onto my lap, while accommodating herself to having my cock inside her. When she had settled down and had my full length in her I began to thrust gently. Karen rocked back and forth on my cock and closed her eyes with an expression of pure ecstasy. I leaned forward to suck on her nipple while I sped up my thrusting and she leaned back to help me manage both. After only moments in this position, Karen suddenly shot a strong second load of cum that covered my balls. She got a glazed look on her face, and put her hands on her knees to help her find leverage. She began bouncing up and down in time with my thrusts, and I really began heating up. Moments later, Karen was sweating and pumping up and down, taking eight inch slow strokes of my cock in her cunt. I began to thrust faster and she matched me all the way. As I got close I reached up and put my hands on her shoulders. I pulled her down on me and as I increased my thrusting I came inside her. I just pushed her down and held still while my cock pumped her full of juice. I kissed her, and held it while my cock got soft. When we stood up we were both exhausted and ready for rest. Later that night we repeated the performance in my bedroom and still later showered together. The End ·
