I suppose it's not 'natural' and certainly frowned upon in most cultures, but when it feels so good... Anyway, Cheryl and I have done some things most brothers and sisters never get to do and I'm glad we did. In fact, we are still finding new things to try thirty years later. The first time was during Christmas when I was home from college. I was twenty and Cheryl was eighteen. Our parents went to visit relatives for a few hours and Cheryl and I were left alone. It's obvious, looking back on it, that she had the whole thing planned out, but it came as a total surprise to me and that definitely made it more fun. There was a bathroom between our two bedrooms upstairs. I heard the shower running when I walked past it heading to my bedroom and wondered to myself why Cheryl would be using it at that unusual time. About five minutes after hearing the water turn off I was ready to leave my room. The bathroom door opened at the same time I entered the hallway. Cheryl had a towel hanging in front of her, holding it in place just above her breasts. Her long, thick, brunette hair was wet and hung down her back as she walked toward me. I watched the towel as it moved between her legs, barely covering her pussy. Cheryl smiled the entire time. She came up to me and stopped, saying, "We're alone, right?" "Uh, yeah. I guess for a while," I stammered. "Good," she replied. "There's something I want to show you." She pushed me backwards with one hand on my chest. I stepped back until we were both inside the room. Then she put her body against mine, with the towel in between, and kissed me. It was a short, innocent kiss. Then I saw her beautiful, big eyes looking into mine and we kissed again, our tongues meeting during a much more prolonged caress. I put my arms around her and felt the cold, bare skin of her back. I pulled her toward me, subconsciously also trying to keep the towel in place. Cheryl took one of my hands and placed it on her breast, over the towel. I pressed on it, still intent on keeping her covered as much as possible. However, the incredible feeling of her soft tit in the palm of my hand began to change my mind. We kissed once more and I felt my cock begin to harden. It must have been the sign Cheryl was waiting for because she placed a hand on it, rubbing it gently through my jeans. "Cheryl, no," I said quietly. "We can't..." Before I could stop her, my sister grabbed the towel and flung it onto my bed. I just stood there and stared at her gorgeous body. Her breasts were only starting to fill out. Her waist was small and her hips perfectly curved. Cheryl watched me look down at the tiny patch of dark hair above her clit. "Touch me, John. Touch me everywhere," she told me. I hesitantly put both hands on her tits, squeezing them gently while she returned her hand to my crotch. I was already thicker and longer and Cheryl was able to feel the outline of my cock. I pinched her nipples and she gasped. Cheryl unbuttoned the top of my jeans and pulled down the zipper. The smell of her shampoo and soap made me want her even more, despite a lingering sense that what was happening was very wrong. I felt the palm of her hand on the outside of my underwear, grasping at my erection. She pushed the jeans down. I reached around and slid my hands down to the top of her ass. As we kissed, Cheryl stroked my cock through my shorts and I embraced both of her tiny little ass cheeks. She was winning and had to know it when I leaned down to take one of her tits into my mouth. I liked the nipple and sucked on her tit until I heard her moan. Her hand slid inside my shorts and finally took hold of my throbbing cock. Cheryl bent down and pulled my underwear and jeans all the way off. Then she ran one hand up the length of my cock before lightly kissing the tip. I considered telling her to stop, but the words never came out. When I felt her tongue on the underside of my erection, I never considered telling her again. The memory of the first time she put me inside her mouth will stay with me forever. Her lips were so soft and her tongue so wet and warm. Cheryl was slow at first, seemingly unsure of herself. Then I began to wonder if, indeed, this was her first time. She gave me a blowjob like no other I'd ever experienced. The combination of her hands and mouth and tongue had me ready to cum within the first minute, but I struggled to hold off as long as I could to appreciate the tremendous feeling. My sister also seemed to sense when I was close, pulling her head back and slowly sliding her tongue up and down my cock while I calmed down. She licked the precum from the bright pink head and then put me back in her mouth and sucked some more. This was repeated until I was ready to explode. I had my hands on the back of her head when I said, "Oh God, Cheryl. Cheryl!" She never slowed down. I felt my cock hitting the back of her throat when I felt the first rush of cum flowing upwards. "Cheryl! Now. I'm...coming!" She couldn't have pulled back if she tried. I held her in place and fucked her face while shot after shot of warm cum filled her mouth. I saw it dribble down her cheeks and onto her tits. I came again and again until it was over and I stood there gasping for air. Cheryl's lips and chin were covered with my cum. She looked up and smiled, her big eyes seeking my approval. "You shouldn't have done that," I managed to say. "You didn't like it?" "I loved it. That doesn't make it right." She had moved over to the bed and was using the towel to clean off. I stepped in front of her and said, "Get on the bed. On your back." Cheryl obeyed and I stood over her, my cock glistening from leftover cum. I leaned down and sucked on a tit, getting the nipple rock hard. Then I did the same to her other breast. I could hear her breathing become faster and harder so I put a hand between her legs. The first thing I felt was the warm moisture coming from her pussy. I rubbed her clit for just an instant, watching Cheryl's body stiffen in response. I moved down and got on my knees between her legs. She spread them voluntarily and I licked my way up the inside of her thigh until I got to her pussy. I avoided it as long as I could, teasing her with my licks and kissed. The moment my lips found her pussy, my sister's ass came off the bed. I slid my hands underneath and prepared to give her the best orgasm ever. "Oh my God, John," was all she could say the first time my tongue ran across her swollen clit. I lifted her up to my face and wrapped my mouth around her clit. Her little body quivered as I attacked her nub harder and harder. I squeezed her ass and listened to her whimper the more I sucked on her. Then I moved down and slid my tongue inside her pussy, watching her arch her back at the same time. The taste of her juices was magnificent. When I returned to her clit, I reached up and massaged her tits, pulling on the nipples and pinching them a little harder each time. "Yes. Yes, John! Just like that," she begged. We went on for almost five minutes, her body trembling as time passed and her orgasm neared. "John! Oh fuck, yes! Yes!" "Cum for me, sis." I licked her clit and Cheryl cried out, "Yes! Yes!" I could barely keep in contact with her clit as she came. I held her by the ass and buried my face deeper into her pussy. She might have cum several times for all I knew, but I didn't let up until her cries ended and she tried to crawl away from my mouth. I threw myself on top of her and we hugged and kissed for the longest time. That night, after my parents were in bed on the first floor, Cheryl came into my room and crawled into my bed. She was naked and quickly took off my underwear. "I want to sleep with you tonight, John," she said before kissing me. "I would like that." I ran my hands across her tits and down her flat stomach until one was between her legs. She clutched at my hardening cock. "I'm sorry, but...but...," Cheryl began to say. "Don't be. I thought today was wonderful," I assured her. "No. It's not that, John," she said, stroking my cock. "It's just that...well...we can't, you know, we can't fuck and I don't want you to be mad." "I won't be mad. But why?" Cheryl edged even closer and said, "Well, I haven't...um...I'm a virgin and I kind of want to stay that way for a while. Is that OK? Can we just...?" I kissed her and rolled on top of her, eventually sucking on a tit. "Of course it is, Cheryl. Whatever you want. I'll do anything," I told her. "Keep doing what you did today and I'll be happy forever." I smiled and said, "Roll on your side, facing the wall." She did and I put my body tight against hers, my cock against her ass and one of my hands on her tits. For the next ten minutes I touched every inch of her body until we were both on the verge of coming. I kissed and licked her neck and shoulder. Cheryl pushed her ass back against me and I let my cock rub inside her crack until I was so hard it hurt. Just as I touched her clit, she rolled over on top of me. In a split second, she turned around and we began a sixty-nine. I held Cheryl by the ass and repeated, the best I could, what I had done earlier to make her happy. With both of us concentrating on the other, it took several minutes of pure pleasure to be ready to cum. Cheryl was first and she lifted her head from my cock to allow her orgasm to come and go. The second my cock was back in her mouth, I came. God bless her because my sister swallowed every ounce of my cum and licked me until I was dry. We slept very well that night with my head on her chest and her arm around me. We were together at every opportunity the rest of the time I was home that year. Although it was very hard to resist, I did not fuck Cheryl, as she had requested. In turn, she made me cum with her hands, mouth and tongue until I didn't think I could have another orgasm. We did it in every room of the house, clothed and unclothed, whenever we were alone or, occasionally, when we could get away with it even when we weren't alone. Years passed quickly and my little sister eventually got married to a nice enough guy who probably didn't give her the attention she deserved. They had two kids by the time Cheryl was in her late twenties. Still, when I saw her, she seemed lonely. She grew even more beautiful and filled out her body perfectly. My lust for her never waned. The year I turned thirty, Cheryl surprised me with the most wonderful present. I traveled a lot for business back then and told her I was spending a night close to her and asked her if she was available for dinner. She answered that she couldn't make it to dinner but, with her husband also traveling, could hire a babysitter and join me in the evening. We agreed to meet in my hotel room. I guess the thought had gone through my head that maybe something would happen, but kept pushing the idea aside because my sister was married. I never wanted to get in the middle of that and cause trouble. Cheryl, of course, had other ideas. When I opened the door when she knocked, I froze in place at the sight of her in a sweater and very short skirt. The moment she was inside and the door was closed, we embraced as if I was back in college again. I held her against the wall and kissed her harder and longer than ever before. Instinctively, my hands were all over her before I caught myself and backed away. "John, I want you to make me cum just like you used to. I miss you so much," Cheryl said. I smiled and said, "OK. But I have a request this time. I want you to strip for me so I can what a beautiful woman you've turned into." Cheryl laughed and said, "All these years I've tried to keep a figure just for you. But get naked first so I can see if you like me or not." I knew exactly what she wanted and I took off my clothes in my own slow strip tease. Once I was naked, I sat on the bed with my cock already beginning to react. Then Cheryl kicked off her shoes and, with a big grin on her face, pulled her sweater over her head. She wore a sheer bra that did little to hide the erect nipples on her full breasts. She unzipped her skirt and let it gradually lower until her tiny panties were visible. Cheryl threw the skirt aside. My eyes never left her breasts as she unhooked her bra in the back and let the straps fall down her shoulders. "They're gorgeous, Cheryl. Just gorgeous," I said. I put my hard cock in my hand, much to Cheryl's delight, as she ran her own hands over her tits and nipples. I stroked harder when she pulled on the nipples just like I used to. Then she got naked and I had to let go of my cock before I came. She slowly turned around to let me see her luscious ass. That's when I had to get up. I held her from behind, letting my erection press against her ass and my hands caress her tits. I never wanted to let her go again. When I touched her pussy she was soaking wet and moaning from desire. "I could cum on your ass right now, little sis," I whispered to her. She giggled and said, "I believe it. Let me do it instead." Cheryl turned and lowered herself until my stiff cock was in front of her face. It was just like she was eighteen again when I felt her lips close around my cock and she began to bob her head up and down. Her hair wasn't quite as long now, but it was still thick and I held her head as she gave me another incredible blowjob. Her hand was around the base and her lips and tongue concentrated on the rest as I came closer and closer to cumming. When my moans signaled to her it was time, she aimed the cock at her tits and stroked me like a pro. I came in buckets, each shot delivering a fresh stream of white cum onto her tits. By the time I was done, even Cheryl's hand was covered in it. "Oh my God you're the best," I told her as she sat on the edge of the bed. "My turn?" she asked, leaning back erotically and spreading her legs. As I approached her, she added, "Same rules apply, John. I want your mouth and tongue." As always, I would do anything for her and I tried to tease her as long as I could before taking her wonderful clit and pussy into my mouth. I played with her tits while she writhed on the bed in delight. I stabbed at her clit with my tongue and thrust it deep inside her pussy. Her legs were on my shoulders when I took her clit into my mouth and brought her to a long, loud climax. We rolled naked on the bed together, each of us cumming two more times in the next hour and a half of mutual fondling. Another ten years passed without another encounter, partly because of the distance between our cities and partly because I think we both knew if we started doing it regularly it would never stop. When I did see her at family gatherings, you could feel the sexual tension between us, but we never acted upon it. So I was ecstatic when I received the invitation near my fortieth birthday to meet Cheryl privately once again. Except, her idea of privately was at her office in a thirty five story building. But I trusted her and counted down the days until we saw each other again. I should have known to never doubt my little sister. Cheryl had fantasies just like the rest of us and, luckily, she chose me to fulfill one of them. I checked in at the security desk of the large office building and received my pass to get to Cheryl's floor. There, I met a receptionist who called my sister and announced that I was there. I sat in the waiting area for only a minute before she appeared. As usual, she looked stunning in a silky blouse and short, black skirt. We hugged and she took me back to her office. It had huge windows that looked out over the city, but that was the only way you could see into the office. I heard Cheryl lock the door after she closed it and she came to me immediately. "You aren't leaving until you've made me cum, John," she said with a grin. "We still can't fuck, but I want the city to see you make me cum." She reached for my cock, which was already getting hard, and she said, "Can you do that, John? You know I'll pay you back if you do." I kissed her so hard she had to lean against the desk to remain standing. All the time, my hands were unbuttoning her blouse and pulling it out of her skirt. As soon as I had access to her bra-covered tits, I clutched at them roughly and heard my sister moan with joy. As I began to kiss her cleavage, I saw the front clasp to the bra. In seconds, it was open and her beautiful tits were exposed. Cheryl was rubbing my cock frantically as I took a breast into my mouth and sucked on it. I bit the nipple just enough to make her cry out and then switched to the other one. A minute later, I stood and took her by the arm. "Over here," I said, pulling her behind the desk and in front of the windows. Standing behind her I pulled aside her blouse and bra, giving the city a good view of her chest. We were twenty one stories up, but there were buildings across the street and plenty of pedestrians within sight. "Is this what you want, Cheryl?" I asked her with a smile. "God, John. I'm so horny right now. Make me cum...now!" I kicked the chair aside and lifted her onto the edge of the desk. I forced her legs apart and pushed up her skirt until I saw her panties. I yanked them off, removing her heels in the process. Then I took the skirt in my hands and lifted it, with Cheryl raising herself a few inches to free the skirt from under her ass. With it completely out of the way, I had access to the clit I knew would let her cum. Cheryl leaned back, her pussy aimed out the windows and her tits in plain sight. I saw the excitement on her face and I let her revel in her fantasy for a moment. I did wonder, at that instant, if anybody in the closest building would happen to look over and watch. I had to admit it was an exhilarating feeling. Then I started to make her cum. All the tastes and smells I was used to from all the years before came back and I methodically worked on her clit and pussy until I knew she was close. I stopped. Started again. Brought her closer. Let her beg me. And then I let my sister cum in torrents. Her muffled cries were music to my ears as she squirmed on top of the desk, pulling my face tighter against her, forcing me to suck on her clit and making her cum again and again. Beads of sweat glistened on her forehead when I was done. I licked her juices from my lips and we both laughed at the intensity of it all. Then I pulled her off the desk and had her lean against the windows, her chest still uncovered. "All these years I've wanted to cum on this tight, little ass. Now I'm going to," I told her. "Spread your legs." I lifted her skirt and threw it onto her back. Cheryl steadied herself with both hands on the windows as I took out my cock and placed it on top of her ass. Soon it was rock hard and I was sliding it up and down her crack. "John! John, I see somebody watching. Do you see that woman straight across maybe one floor above us?" she said excitedly. It only took a second to spot the middle-aged woman. I smiled, as I'm sure Cheryl did, at the sight of her hand inside her pants. I never felt as aroused as I did at that moment. "Got it," I said. "Let's give her a real show." I turned Cheryl slightly so the voyeur could see my cock, or at least knew where it was the whole time. Then I grabbed my sister by the hips and forced my cock up and down her ass, using the cheeks as substitutes for hands. It didn't take long. "Almost there," I warned Cheryl. "God, I'd like to do this all day." I had another thirty seconds. Decades of Love "Yes! Now!" I pressed as hard as I could. The first spurt of cum landed on the inside of the skirt. Then a pool of white cum accumulated at the top of her ass as I continued my orgasm. I leaned back and groaned, finally taking my cock in my hand and finishing myself off with the last few drops I could put out. "Look at her," Cheryl exclaimed. "She's cumming, too. How cool is THAT!" Without a doubt, the woman was steadying herself on a window sill as she came. She was bent over farther and farther, reaching between her legs to get the last ounce of pleasure from her clit and pussy. We saw her mouth open wide and then close as she looked our way one more time and then turned and disappeared. "Jesus, that was great," Cheryl sighed. "There's some Kleenex in that drawer." She pointed and I cleaned her ass the best I could before we began to dress again. So, here I am just a few days from my fiftieth birthday. Cheryl's kids are young adults and she and I are quickly approaching the end of middle-age. Every time I see her I think she is sexier and sexier. Her hair is shorter, but perfectly styled. She looks like she could run a marathon. I get hard just thinking about her. And that reminds me that there is only one thing I've never done with Cheryl, but I honored her wishes and I am proud of that fact. Still, if I ever started a bucket list, it would be number one. I got an unusual e-mail from Cheryl the other day. All it said was, "I want you. Tell me when and where." Of course, I wanted to make it special and I'm a little better off financially than ever before, so I looked at my work calendar and found the next date I would be in her neighborhood. When she confirmed she would be available, I booked a suite with a whirlpool tub and invited her to the room, without giving her the details. I was surprised to see her in a rather formal dress when she arrived on the designated evening. But she looked exquisite in the low cut neckline, slimming waistline, and curve-hugging material that flowed almost to her ankles. "You are an angel, Cheryl," I said as I closed the door and we kissed. "How do I survive all this time between our visits?" "I assumed you hooked up with that woman from the office building across from me," she said. I laughed and slapped her ass while we entered the suite. "Wow. Look at this," she said in awe. "I remember far less fancy rooms." "All I remember is you being there," I said, taking her in my arms again. "I have a surprise for you, John." "What is it?" I asked. She seemed to blush and, after a short pause, said softly, "I want you to fuck me tonight, big brother." I couldn't have possibly held her any tighter. My hands glided up and down her back until I rested them on her ass. I squeezed for a second and then asked her, "Are you wearing panties?" "Of course not. No bra either. Why would I? I was coming to see you," she explained with a grin. "So, when do I get to try out that whirlpool?" The tub was in a corner of the suite outside the bathroom. Cheryl had to know it would be soon when she ran a hand over my cock and felt how hard it was. "I brought some of your favorite wine," I told her. "Let's have that first." "You know you don't have to get me drunk to have sex," Cheryl laughed. "You're just teasing me." "I wanted this visit to be special. You just made it even more special. I think we should celebrate." I couldn't take my eyes off my sister's fantastic body as we sat in the living area and got caught up on news while drinking. Each time she moved in her chair the neckline of her dress shifted to reveal more of one breast and then the other. At times it seemed a nipple would surely appear from underneath the material, but each time I was denied the pleasure. After nearly half of hour, Cheryl said to me, "Get undressed, John. I think your cock needs more room." I laughed and leisurely starting removing my clothes while she sat, watched, and drank her wine. Long before I had my boxers off she could see the tent my erection created. It did feel good to finally release it and stand naked in front of Cheryl. She rewarded me by slipping a hand inside the front of her dress, massaging one of her tits. "You still look wonderful," she said, inspecting me from head to toe. It never embarrassed me to stand in front of her with a hard-on. We both knew what it meant and on this night it never had as much meaning. "Now come get me undressed," Cheryl said, standing in front of her chair. She turned her back to me, giving me access to the zipper of her dress. But first I had to wrap my arms around her and feel the softness of the skin revealed by the dress' neckline. My fingers slipped lower and lower until disappearing under the material and finding the nipple of her left breast. She sighed when I squeezed it, pushing her ass back against me. Only then did I reach for the zipper. Her shoulders were fuller than when she was eighteen, but she always had perfect skin and when I lowered the straps of the dress down her arms I couldn't resist kissing it. I watched her flawless tits come into view. My cock throbbed as it rubbed against her dress. I let the material fall to the waistline and caressed her tits. Then I pushed down on the dress and slipped it over her hips and ass. It fluttered to the floor without a sound. My sister and I were naked once more...just like it should be. Cheryl stepped out of the dress and walked over to the tub, my eyes locked onto her ass as it swayed. She leaned down and turned on the jets, smiling as she stood back up and looked over at me. "Plenty of room for two," she said. Cheryl stepped into the water and carefully moved into place at one end, facing me. She sat and gradually let her body sink lower until the swirling water was bubbling around her tits. She closed her eyes. The smile on her face was priceless. I climbed in and reclined, facing her. Our legs were intertwined comfortably. I thought I was in heaven. As if I needed to be more aroused, Cheryl's foot found my cock and gently rubbed it under the water. Her toes worked on the thick head of the cock, seeking out that magic spot underneath that makes me hard as a rock every time. Eventually, she pushed herself up and came over to me, water dripping off her chest as she leaned forward. "I think you're ready for me," my sister said. "I've been ready for thirty years, Cheryl." She straddled my legs and reached down for my cock. It stood like a pole as I shifted into place and she slowly lowered her body. There was nothing hurried about her actions. It was as if we'd done this dozens of time. But we hadn't. This was the first time and Cheryl hesitated just as I felt the tip of my cock come in contact with her pussy. Cheryl looked at me and said, "I love you, John. I always have." "I love you too, Cheryl. More than you'll ever know." The head of my cock spread the lips of her pussy. The first inch or two slid in and then Cheryl gently lowered herself onto me. God, what a feeling. It was everything I imagined and more. I could feel her pussy gripping my thick cock and when I began to slide it in and out it felt like a hand holding me tightly. Cheryl lowered her tit to my face and I eagerly sucked on it, giving equal time to each one as we began to fuck more intensely. I held onto her ass, marveling at how little it had changed in all the years. Cheryl said softly, "We're going to do this more than once, John. So don't hold back." The words alone almost made me cum. But I was in no hurry to end one of the greatest feelings ever, so I let her ride me for several more minutes, licking and sucking her tits almost the entire time. Cheryl put a hand between her legs and worked on her clit. I loved watching her face change expressions as she came closer and closer to her orgasm. Her mouth opened to let out little whimpers and she closed her eyes tightly to enjoy the sensations. Soon, she was upright and I held her tits in my hands. I watched her tilt her head back as she moaned loudly. "Oh yes. Fuck me harder, John." I slammed my cock into her as fast and hard as I could. Water splashed around us as we both prepared for the climax. "Yes! God, yes. I'm...so...close," Cheryl cried out. The only warning I gave her was a massive grunt. Then I erupted inside her. Cheryl came simultaneously and our moans echoed throughout the suite. Even in the churning water, the sound of our bodies smacking together could be heard. My sister begged me to keep going. I clutched at her tits, leaving red marks everywhere a finger dug into them. For many seconds after my orgasm had ended, Cheryl made herself continue cumming by furiously rubbing her clit. Then she collapsed on top of me. We reclined in the water without saying a word, my semi-rigid cock still inside her. When she squeezed me with her pussy and I groaned, she laughed. I slapped her on the ass. "Well? Was it worth the wait, brother?" I kissed her. "Well worth it. You're amazing." We got out of the tub and I used a towel to dry off Cheryl and myself. It certainly made me flash back to the first time I saw her with a towel in the hallway of our house. When I was through, she insisted we stay undressed and we both poured another glass of wine. Sitting there relaxing and talking, seeing her beautiful body the entire time was a delightful experience. Occasionally, she got up to walk around the suite and check out all the rooms, but I'm pretty sure she only did it to let me watch her and get hornier and hornier. The final time she did that, she sat in her chair, spread her legs, and leisurely slid a finger up and down over her clit. My cock reacted accordingly. "Are you ready for another session?" she said in a near whisper. My heart pounded. I felt the blood rushing into my cock. "I'll always be ready for you, sis." She smiled and said, "It's your choice this time." Little did she know I had been thinking about it since the time we got out of the tub. "I do have something in mind," I told her. "But why don't you come here and get me ready first. Just like you always did before." This time I was the one spreading my legs while she kneeled in front of me. To my delight, Cheryl treated my cock like a precious gift, softly fondling it with her hands before sliding her tongue up and down the shaft. Only after I was good and hard did she put it into her mouth and suck on it like always. "As much as I like that, I need you to get up," I finally told her. As she stood, I said, "Walk to the bed." I was right behind and put my arms around her when we reached the foot of the bed. "Remember the office window? This time it's just you and me and I'm NOT going to cum on your ass," I said. "Now put your hands on the bed." As she bent over, Cheryl's legs separated just enough to give me access to her pussy. I put my cock in place, but just as she had done in the tub, I delayed the inevitable. Instead, I rubbed her clit. "Tell me what you want, sis." "I want you to fuck me, John." "Beg for it, Cheryl." I rubbed her clit harder. "Oh God, John. Please fuck me. Now." I thrust forward and my cock vanished inside her soaking wet pussy. She screamed with delight and I grabbed her tit. I pulled back a little and slammed into her again, resulting in another squeal. Soon, the bed creaked as I fucked her faster and harder. I held her by the hips and Cheryl used her own hand to massage her clit. "Yes, John. Fuck me. Fuck...me!" I banged her from behind so hard her ass cheeks were turning red. Cheryl's fingers clutched at the bed covers and her head bobbed as the intensity of our fucking increased. Each time my cock pulled back, my sister's juices shined in the light on every inch of it. And she was still SO tight. "Now, sis. I'm cumming," I warned her. Her pussy tightened and I slammed into her, feeling the first spurt of my cum pour out. Then another thrust and another gush. Cheryl started to cum and her body quaked violently. I just kept fucking her until I was empty, letting her finish her own orgasm. Her arms gave out and she was flat on the bed with me on top, my cock still inside her. I managed to spurt out another few drops with a couple of small thrusts. Then it was over. "Happy fiftieth, John," I heard Cheryl mutter. "Thank you. What are you doing in ten years?"
