I was 16 years old the first time I fucked my step dad, and yes, in case you were wondering, I fucked him, he didn't fuck me. I had wanted him for awhile, and when the opportunity came up, I jumped on it, or should I say I jumped on him! I was at the mall one day with my friends and had been doing a lot of flirting. It had gotten me very turned on. I guess I am a bit of a tease! Any way, when I got home my step dad was home alone. My mom was out of town at for the weekend and I knew my brother wouldn't be home until late that night. When I walked into the living room there he was, the object of my desires. Bob was 43 and a little behind the times, but I thought he looked really hot and I had always thought that since Mom saw something in him maybe I should check him out for myself. I think I had probably wanted him for a couple of years, but it had gotten worse since I had lost my virginity about 6 months before. I wasn't in love with him or anything, I just wanted to try some more experienced cock and I was attracted to him. "Hi, baby doll," he said to me without looking up from the game he was watching. Two things about that irritated me. First, the baby doll thing, and second, he paid no attention to me. I thought to myself, "This guy is about to get a wakeup call from his "baby doll." I walked in front of the TV and said, "Hi, Bob." He looked up and I saw him glance nervously at me. That was when I realized why it seemed like he ignored me all the time. I turned him on and it embarrassed him! "This might be easier than I thought," I thought to myself. I could see his eyes going up and down my hot bod as he asked me, "How was the mall?" "It was great," I told him. "Lots of cute guys, and I did a lot of flirting, but they all seemed a little nervous when I talked to them. Why would they be nervous, daddy?" Bob looked at me and said, "Well, ummm, it could be because, well, ummm...." I could see him turning red and he was really struggling with this so I decided to help him out. "Is it because they think I look really hot? Do hot girls make guys nervous?" Maybe I should describe myself to you so you can see what my step dad was going through. When I was 16 I was about 5'2", with long blonde hair, pretty green eyes, and cute pouty lips. My measurements were already 34c- 22-34. I was a cheerleader and ran track so my body was really hard and I loved to show it off. That day I was wearing a tight, short belly shirt, (my navel was already pierced), a short skirt, thigh hi stockings and heels. I had on just enough makeup to look good and my nails were done in a nice sexy French manicure. In other words, I was hot and I knew it! Getting back to Bob, he was stammering still trying to answer my question, so I decided to keep the pressure on him. "Do you think I'm hot?" I asked him. He managed to croak out a very nervous, "Yes," which caused me to smile. "Daddy," I asked, "do I turn you on?" He was staring at me with a look of shock on his face and all he could do was nod. I walked towards him, asking "Are you turned on now?" I stopped right in front of him. He didn't even attempt to answer as I bent down and grabbed his crotch. I could feel his half erect cock in his pants and smiled, looking up at him. I could tell he was looking down my shirt. I gave him a squeeze as I replied for him, "I guess you are!" He had always seemed so self confident before this, but now this big 43 year-old man had been turned to Jell-O by a 16 year-old girl. I really liked the feeling of power I had over him and I decided to use it. I kneaded his stiffening cock with one hand while with the other I pulled up my little t shirt. My boobs were in a white lacey bra that was a size to small, causing them to spill over the top. I thought his eyes would pop out of his head as I pulled the left cup down and my firm young tit popped out. I put a manicured finger on my pink nipple. "You want that, don't you," I said, more as a statement than as a question. "Suck on it, daddy," I whispered to him. I hadn't called him daddy in years, I just wanted him to remember that it was his 16 year old step daughter he was having sex with. He looked at me as if in a trance, a look of bewilderment on his face. Then, as if drawn by a power he couldn't resist, his head bent forward and took my nipple into his mouth. I knew I had him and that there was no turning back now. I moaned a little as he sucked, then he reached up and gave my tit a little squeeze. Damn, that felt nice! I pulled my shirt all the way off and pulled my other breast out of its little holster. It was kind of uncomfortable having the bra pushing up on my 34c's, but I knew it made them stand up and look really hot. I climbed onto my step dad's lap and pressed my chest into his face. Bob found his head between two perky teenage tits and he went wild: sucking, biting, pinching, pulling, squeezing, kneading. I am very sensitive to breast play so this was driving me wild. I would have thought that an older man would have been a little calmer about the whole thing than the teenage boys I had been screwing around with, but instead he was more passionate and aggressive than anyone I had ever had before! (Not that at 16 I had fucked a lot of guys. I'm not a slut, you know!) I was getting really hot, and I wanted to play with his cock. I slid back on his lap and reached between my legs to unzip his pants. After they were unzipped I got off his lap. (He looked so sad when I pulled my hard nipples out of his mouth!) I quickly dropped to my knees between his legs and helped him slide his pants down. I was surprised when his cock popped out. It wasn't very long, maybe seven inches, but it was really thick. It was much thicker than any of the cocks I had seen, and he had a lot more pubic hair too. I wrapped my hand around it and gave it a few strokes. It was already hard, but it seemed to stiffen even more and he let out a low moan as I began playing with his rock hard pole. I looked at it as I stroked it, studying the big purple head and the veins that ran along it. It was actually kind of scary looking, especially when I thought that soon it would be in my tight pussy. I fell in love with his cock then and there! After I had run my hand up and down it I decided I really wanted to suck on it. I glanced up at my step dad; he seemed to be in heaven with a silly look on his face. I circled the base of his rod with my hand and leaned forward, my tongue extended. When it touched his cock I felt it jerk. That really excited me! I circled the swollen purple head of his cock with my tongue , then I licked it through the pee slit at the top. A drop of precum was there and I tasted it. It tasted a little salty, but I liked it. I pulled my head back to look up at my step dad, and the cum stuck to my tongue, leaving a string of it connected to his cock. Later on he told me he almost came when he saw that. I smiled at him and went back to his cock. I opened my mouth and slipped my lips around his cock. I started sliding them up and down, going down a little further each time I slid down. I was still gripping the bottom of his shaft and with my other hand I started fondling his balls. He seemed to really like this; his hips started moving up and down like he was fucking my face. I stopped sucking again and looked up at him. I kept stroking his cock with my hand as I smiled at him. "Am I doing this right?" I asked him. Of course I knew I was doing it right, I just wanted to sound innocent so I could turn him on. I think it shocked him when I spoke to him; he just looked at me and stuttered before answering "Oh, baby doll, this is perfect! So perfect!" I said to him, "Good, daddy, I just want you to feel good." I started sucking him some more, and soon my face was almost in his pubic hair. I still had about two inches of cock to go but I could feel it bumping the back of my throat. I started pulling my head back until just the tip was in my mouth, then quickly sliding down the five inches of cock I could fit down my throat. This was really getting to him, I could feel his cock jerking in my mouth. I had given a couple of blow jobs before and I could tell he was about to cum. I wasn't sure if I wanted him to. I had heard that old guys had a hard time getting it up again. I was so turned on though, I decided to risk it. I just wanted him to cum so badly! I wasn't sure if I wanted him to cum in my mouth, either, but he settled that for me. I had pulled my head back and just had about a half inch of his cock between my lips and was pressing my tongue to his piss hole when he started to cum. The spew hit my tongue and, instead of going down my throat, bubbled out from between my lips. Big droplets ran down my mouth and dripped off my chin. Quickly I sucked him back into my mouth and I could feel the next jets of cum hit the back of my throat. I jerked his cock with my hand, trying to milk it dry. My step dad gasped and moaned and his hips jerked up and down as he came hard. I kept sucking until he started saying, "Stop, stop, stop!" He pushed my head away and looked down at me. I can just imagine what I looked like, his sweet young blonde step-daughter with drops of his cum dribbling down my chin. I scooped it up with my fingers and licked them clean. I climbed back onto his lap and kissed him. I wasn't sure if he would kiss me: one boy I sucked off wouldn't kiss me after he came in my mouth. My step dad wasn't like that though, and he gave me a deep passionate kiss. After we broke off the kiss I pulled my shirt the rest of the way off, but I left my bra on because I knew what it did to my tits. Then I climbed off his lap and pulled my little thong off. He watched intently as I stepped out of it and sat next to him on the couch. I sat kind of sideways and lay back against the armrest, then pulled my skirt up. I thought his eyes would pop out of his head when he saw my shaved pussy all wet and glistening for him. I took the middle finger of my right hand and ran it up and down the slit a couple of times, then I used my fingers to pull my pink pussy lips apart. I wanted him to see how tight and small my little fuck hole was. I wanted him to play with my pussy but he was just staring at it, so I reached down with my other hand and started rubbing my clit. It was harder and more swollen than I had ever felt it! I looked down and I could see it poking out from between my pink lips. I rubbed the tip of my finger across it, then I slid my finger down my juicy slit and slipped my finger inside my wet pussy. It felt great so I closed my eyes and lay there for a moment enjoying the feeling of finger fucking myself. When I opened my eyes Bob was still just looking, so I asked him in a sweet but sultry voice, "Daddy, don't you want to eat my pussy?" He blinked a few times, then nodded. He got down onto his knees, then pulled me around so that I was positioned right in front of him. He flipped my legs over his shoulders, then lowered his face to my pussy. An electric shock ran through my body when his tongue touched my clit. I trembled and felt good all over. His tongue ran slowly up and down my wet slit, lapping up my juices. I felt it slip into my love canal and swirl around in there, then he focused on my erect clit. It was driving me crazy having this old man licking my most private parts. I could feel his whiskers on my thigh and that turned me on as well. Next he cupped his hands under my ass and lifted my crotch to his face. His tongue put more pressure on my hard nub and I began wiggling around on the couch. I grabbed my firm tits and began kneading them like two handfuls of dough. I was gasping and moaning as he licked faster and faster, and soon I came hard, squeezing his head between my legs. He kept licking and sucking at it, and I kept cumming harder and harder. Soon my whole body was trembling and I was moaning loudly. It seemed like every muscle in my tight young body wanted to contract at the same time. How long this went on for I couldn't say, but when Bob stopped it seemed like it hadn't been nearly long enough. After he stopped he looked up at me from between my legs and smiled, my slick wetness all over his face. "I'll bet you never came like that before, have you?" he asked. All I could do was shake my head from side to side in reply. Bob dropped my legs off his shoulders then stood up. He was still dressed in a t shirt and jeans, but his cock was still hanging out and it was semi-hard. I gazed at it and kept rubbing my breasts almost absentmindedly. Bob took his cock in his hand and rubbed it gently as he looked down at me. I think we both needed a moment to rest up for what we both knew was coming next. Finally Bob started taking the rest of his clothes off while I slipped off my skirt. Now all I was wearing was my lacey white bra with the cups pulled down, my white thigh hi's and my white heels. Soon my step father was undressed and his cock was hard again. He stood there stroking it again while I lay back on the couch rubbing my pussy. After a long moment I whispered to him, "Fuck me, Daddy." He sat next to me on the couch and grabbed my arm, pulling me to him. Without saying a word he positioned me so that I was straddling his lap, facing him, my pussy over his cock. He grabbed the base of his shaft to hold it steady while I reached down with one hand and spread my pussy open. With my other hand on his shoulder to steady myself I slowly lowered my little fuck hole towards his thick, meaty fuck rod. I looked down and watched as it touched my pussy lips and then start sliding inside me. It was a tight fit at first and I could actually feel it spreading me open, but I was very wet and it slowly penetrated me. When I had sunk all the way down onto of it I stopped and just sat on his lap and enjoyed the feeling of his cock inside me. I hugged him and put my head on his shoulder. We stayed like that for a long time, but then I could feel urgings inside me and I began rolling my hips around. He whispered to me, "Oh baby doll, you are so damn tight, you're the tightest fuck I've ever had!" It made me feel good to hear that and I started sliding up and down his cock, slowly fucking my step dad. His hands pushed me back, opening some space between us. I was disappointed, wanting to feel his body against mine, until he grabbed my tits and began playing with them. That felt soooo good! I slid my hips forward until I could feel the head of his cock right in the entrance to my pussy, then I would slide back until he was all the way in me. I looked down and could see that every time his cock pulled out of me it was pulling my pussy lips out as well. His cock was all shiny with my juices and it made a squishy sound every time it slid back into me. I was more turned on than I had ever been before. It wasn't very long before I started to cum. It started in my pussy. I could feel my muscles tighten up, then my whole body began trembling. I couldn't hold my head up and it flopped to the side. I still had my hands on his shoulders and I was fucking my step dad faster and faster. He reached behind me and grabbed my ass and helped me move back and forth. He leaned forward and took one of my erect, pink nipples in his mouth and sucked on it. My other breast was bouncing and wiggling as I fucked his big cock faster and faster. The friction of his penis sliding in and out of me drove me wild and I came harder than before. I was gasping, squealing, moaning with ecstasy as I felt our passion wash through me. Bob dropped my tit from his mouth and leaned his head back. He grunted, then said "I'm coming, baby, gonna cum inside my baby doll!" His body jerked a couple of times and his grip tightened on my ass. I couldn't feel it, but I knew his thick shaft was shooting his load inside me. His eyes closed and his hips thrust up hard several , driving his meaty shaft deeper into me. He gasped each time, and each time I met his thrust by sliding my pussy down onto his cock, wanting this cum to be the best cum he had ever had. I think in some way I thought I was competing with my mother. After awhile his thrusts grew less vigorous. He put his arms around me and pulled me close. I rested my spent body on his chest, both of us breathing hard. As we lay there I could feel his penis shrinking inside me, until it finally dropped out. As I lay my head on my shoulder he said to me softly, "Damn, baby, that was good. That was so damn good! I've wanted you for so long now..." "And I've wanted you, too. It's too bad it took so long for us to get together," I replied. "I know, honey. You are great! I guess it's safe to say you weren't a virgin?" I giggled. "No dad, I've been having sex for almost a year now." "I thought so. But there are some things we need to talk about." "Like what?" I asked him. I thought I knew what he was going to say. "Well, baby doll, first there's your mother. I really don't think she would be happy if she knew we were having, well, you know..." he said as he blushed. "You mean if she knew we were fucking, daddy?" I said sweetly. "Well, yes hun, she would really be pissed. We have to keep this quiet. I do want to have sex with you some more, if it's ok with you?" he asked almost shyly. "Of course we can't let mom know. She would kill us both! And I do want to make love to you again!" I replied. "Ok, but you know we can just have sex, we can't be like boyfriend girlfriend or anything like that." "Of course. I mean, I love you for being my step dad and all, but I don't love you like that, not like mom does. I just think there is a lot you can teach me about love making, and I want to be the best at it. I really like having sex, but I think there is a lot of stuff I'm missing and I want you to show me what to do. Can you do that, daddy? I asked. "Of course, sugar," he said. "I'll teach you whatever you want to know. Maybe we can start this evening. Your brother won't be home until late." "Oh, thank you, daddy!" I said as I snuggled up against him. Like I said, I wasn't in love with him, not like that, but it felt so right being with him. I was really looking forward to my next "lesson" with my step dad.
