I live alone, or should I say that I have lived alone since the tragic death of my wife. She died in a car crash a little over a year ago. It was really hard for a long time, and since then, I've done nothing but immerse myself in my work. My saving grace was my sister Lisa and her two boys. You see I work in the city all week but I live in a seaside community that my wife and I loved. We have a built in pool, and the beach is a block away. The boys love it, and they started to come out on weekends as soon as the weather got nice this spring. My sister's ex gets them every other weekend. Well one Sunday evening when they were leaving I absentmindedly said to my sister. "I'll see you next week." "No." She replied." Jimmy has the boys next week." "Oh." I thought. "Why don't just you come out?" "Really!" She sounded surprised. "Absolutely, this house gets pretty lonely by myself." "You're sure Bill?" "Yes." "OK, great, I'll see you next week." Well Friday came along, and after my sister called me a few times during the week to reassure herself that it was OK. She showed up right on time at 7:00. I got us a couple of beers from the outside bar, and we sat by the pool and talked. "You don't know how much I appreciate this." My sister said. " Otherwise I'd be stuck at Mon's all weekend. You have to know my younger sister. She is an absolutely stunning, tall, blond. She's a yoga instructor so she keeps herself in great shape. She could have her pick of any guy, but her divorce is still pending, and her ex is fighting her for custody of the kids. "He doesn't want them." She told me one day. "He wants to move on with his new girlfriend, but he's using them as a legal ploy so that he won't have to pay me so much support. So my lawyer tells me that I have to give up on any kind of social life. No going to bars, no hanging out with my girlfriends, and especially no boyfriends. If I do, my ex could say in court that I'm a bad mother. Amazing right, his girlfriend lives with him, and I have to be like fucking Mother Theresa!" I looked at her in the patio lights. She was still beautiful. Even after two kids, and seven years married to an idiot. "Don't worry about it." I assured her again. "I can really use the company." "It's just that I wouldn't have any life at all without you." She said, almost crying. "You're a good brother, and I wish that there was some way to thank you?" "I'll figure out a way." I replied innocently, but it perked up my sister's ears. "Oh you will, will you?" "What? Oh, I didn't mean it like that." I said blushing. "I know you're lonely, but..." "I didn't mean it like that." "I know. Not that I would mind. You know how long it's been since I've been with a man?" "Ah, no." "Well, this divorce shit has been going on for over a year, and Jimmy and I weren't doing it at the end." "A year and a half?" I asked. "At least. I've started looking at the mailman funny." "It's funny." I wondered. "We're both fairly attractive and lonely, at least you're attractive." "Don't forget horny!" My sister added. "And don't sell yourself so short. I've seen those new six-pack abs you're sporting." "Well, if we were just good friends, we could get liquored up and give each other... Well you know." I said embarrassedly realizing where I was going with the conversation. It became very silent as we both pondered the situation. We had another couple of beers and engaged in a little small talk. Then my sister said it was late and she was going to her room. "We going to the beach tomorrow?" Lisa asked. "If you want." "Yes I want." And then she walked over to me and sat at the edge of my chaise lounge. "Thanks again for everything." Somehow it was different. I could smell her perfume, and I noticed her nipples poking though both a bra and tank top. She leaned over and kissed me. Not on the cheek, as she would normally do, but on the lips. I tasted lipstick for the first time in over 15 months. It was definitely different as she got up and her hair brushed my cheek. I then watched her ass as she walked to the back door of the house. That night, before I fell asleep, I jerked off, and tried not to think about my little sister. The next morning, after breakfast, we headed for the beach. If I had any thoughts of checking out my sister's body in a bikini, they were quickly dashed. I forgot about her "Mom" bathing suit. I wouldn't describe it as sexy. It's a one piece with a skirt. I put down the beach chairs and as I sat in mine, Lisa took off her tee shirt and shorts. I almost laughed when I saw her in it. "What?" she asked. "What's with the suit?" "What's wrong with it? You've seen it before." "A little matronly, don't you think." "Hey I'm the mother of two boys." 'Not this weekend you're not." "I'm sorry to disappoint you, but this is all I got." She said a little hurt. "I'm sorry Lees, I'm being rude." I apologized. I kept forgetting about her money problems. "Listen, later we'll go back for lunch and then we can stop by the Surf shop and see what they have." "That's alright, I can't afford a new suit" "I've got it." I insisted. "You do too much already." "Don't you remember I'd figure out a way for you to pay me back." I kidded. She laughed. "OK!" It was all right. "Besides, I don't want anyone thinking that I go to the beach with my Mom." After a couple of hours, we walked back to the house and had lunch. I made us a couple of tall, and strong gin and tonics. "Wow that's good, but strong." Lisa exclaimed. "What are you trying to do get me drunk?" "Yeah, I want to see if you'll get a thong bikini." "Yeah right, you'd need about ten of these to get me in one of those." She insisted. "Look about that. It's really sweet of you to offer, but I can't let you buy me a swim suit." "Listen, you're my sister, and I know you're going though a hard time, both emotionally and financially. You know after Annie died I was really bad off. The only thing that got me through it, and helped me to forget, was work. The strange thing about it is that the boss is thrilled with me. Just a month ago I got promoted." "Really that's great!" "Yeah I guess, but I felt a little weird about it. My boss John told me that after Annie died he didn't know what they were going to do with me. He knew how much I loved her and he figured that I would either quit or he would have to let me go. Instead, I became super-worker, and now a year later, he's promoting me. You know I was dead for a really long time. It's only after you and the boys started coming out here that I really started to feel alive again. The point is, that I'm now more financially secure than ever, and you and the boys have done more for me than I could ever do for you." Lisa walked over to me and put her arms around me, and then she kissed me. once more on the lips. "Let's have another drink, and we'll go. But no thongs!" I made another drink and then one for the road. It took us about ten minutes to walk to the surf shop. Once inside I looked at all of the suits, and I found myself a seat. I was thankful that I had brought a drink for the road. I knew the storeowner for years. Annie used to always shop there. "Barbara," I said to the shop owner. "...this is my sister Lisa." Barbara's attitude went from professional to friendly, and then she and my sister became fast friends. "What size are you Lisa?" "I'm a 36C." They started to go through all of the suits and I thumbed through a bikini catalog I found. It was a good catalog, filled with young girls in great suits, even some thongs. I was well entertained when my sister started off for the dressing room with an armful of suits. After a few minutes, Barbara asked how she was doing. "I got the first one on, but I don't know?" "Do you want me to look?" Barbara asked. "Yes." Barbara opened the door and went in. "What do you think?" Lisa asked. "I don't know?" "Yeah, right?" Lisa intoned. "Try the next one on." Lisa said as she exited the room. That started a whole process of my sister trying suits on, and Barbara coming in to give her opinion, bringing suits in and out as she went. One time while Lisa was trying on yet another suit, Barbara passed me and saw that I was on the thong page of the catalog. "How are you doing Bill?" "Good." I answered. Though I knew that's not what she meant. "We were all very worried about you after Annie passed." "I know, and I appreciate it, but I'm doing better. Lisa is helping me get out of my shell." "She's a good sister." She said. Then nodding to the catalog in my lap. "See anything you like?" I then realized that the catalog was still open to the thong section. "There's some nice suits in here." I blushed. "Especially the thongs." She quipped. "Let me show you the one I wear." She then kneeled down next to me and started to finger through the pages. I just hoped that she didn't notice the hard on I was trying to hide. I really was horny if a bikini catalog could get me all hot and bothered. She stopped and pointed to a red and white patterned one. "I bet you look better in it than Her." I flirted. "You'll have to come down to the beach by Arizona Street to see." With that Lisa called to Barbara to help her. I was alone again, and I picked up the catalog to get a good look at the model in the thong. She had a great ass, and I looked again at Barbara and then back to the model, and tried to imagine Barbara in the suit. I bet she would look pretty terrific in that thong. "What do you think?" I heard Lisa ask. "WOW!" Barbara exclaimed. "That's what I thought, but it's a string." "So what. You've got the body for it." "Thanks, but I'm a 32 year old, mother of two." "Well it looks great on you, and if I where you I'd get it." "You think? It does look good, doesn't it? I don't know. I've got a couple more suits to try on, but I think I've got it narrowed down to three." Barbara walked past me again flashing a big smile. I really started to look at her differently. She was very pretty, on the young side, with long straight black hair. She was wearing linen shorts that didn't show her ass off very well, but she had on a clingy pink and white striped Henley with more buttons down the front than usual. I knew because there was definitely an extra button unbuttoned since we first walked in the store. I could now definitely see her bra and some nice little cleavage. Her breasts were average in size, but she definitely had a nice and toned body. She came back to me with another catalog. This time it was lingerie. "You might enjoy looking at this." She said as she handed it to me. "Very nice." "Let me show you what I just ordered." She said as she knelt down next to me, and started thumbing through the magazine in my lap. I could smell her perfume and I could see right down her shirt. She was wearing a bra, so all I could see was cleavage and her white bra, but it was enough. Especially since every time she turned the page, her finger would brush against the hard on in my pants. "Here." She said as she stopped fingering through the catalog. It was a shot of a model wearing a white lace push up bra and a matching thong. "Very nice." "Yeah, I like their stuff, but the only problem is that I have no one to wear it for." "No boyfriend?" I asked as I got a last glance down her shirt. "No one serious." "Pity." Was the only thing I could come up with. 'OK, you guys want to see the ones I narrowed it down to." Lisa yelled from the dressing room, breaking the spell. "Yes." Said Barbara. "OK, this is the first one." she yelled as the door opened. "You're kidding." I said as I looked at the black two piece she was wearing. "What?" She smirked. "It's a bikini." "Are you wasting my time? That's just a two-piece version of your 'Mom' suit." "OK, OK." She said as she headed back to the fitting room. "I'll put on the next one." A few minutes later she reappeared wearing a blue number. This one was definitely a bikini, but a safe one. It had a halter-top, and a hipster bottom. It was nice, and you could just start to see what a great body she had, but it definitely wasn't sexy. Not by today's standards. "Well?" She asked "It's nice." "Just nice?" "Yeah, it's OK." "Just OK? I thought it was nice." "Show him the string." Barbara chimed in. "Yeah, show me the string." I repeated. "No, that suit is not even being considered. "Why not, you look great in it?" Barbara added. "I'm not wearing a string bikini." "Just put it on, and let us see you in it." I commanded. "OK. But we are not buying it." The phone in the shop rang and Barbara excused herself to answer it. A few more minutes later, and a goddess walked out of the fitting room. The look on my face must have said it all. "You like, huh." Lisa said amused. She wasn't just stunning, but hot!! Really hot!!!! "It looks good on me right?" She asked shyly. "Lisa, if you weren't my sister I would say you were hot." "And what would you say if I were your sister?" "That you really look hot!" "I know, but it's much too revealing. Look at my ass." She said as she spun around on her tips toes. It doesn't cover anything." She said and looked at me. She must have seen the look of pure lust on my face, because she spun back around again. "Maybe you shouldn't look at my ass." She quipped. Just then Barbara came back, and looked at Lisa with a smile. She then turned to me. "She looks great, doesn't she? She was born to wear that bathing suit." I couldn't take my eyes off of her. "It really looks that good?" Lisa asked again. "That's it Barbara, wrap it up, we'll take it." "No we're not." Lisa protested. "Listen Lisa, that's the only suit I'm buying. We're done." "I don't know?" Was her only remark? I paid for the suit, and we started walking home, but not before Barbara reminded me to come see her at the beach. " That sales girl really wanted you. I have all of this lingerie and no one to wear it for." She mocked. "That brazen hussy." "I was a little surprised, she seems a little young for me." "Why don't you ask her out?" "Yeah, I would make a great boyfriend. Why are you crying Bill? Oh no reasons, I just really miss my dead wife." Lisa's only response was to hold my hand. Back at the house we went right to the outdoor bar and got a couple of beers. We sat by the pool and made small talk and decided on take-out for dinner. After dinner we sat by the pool and had some drinks and talked. After a few drinks the subject got back to sex. "Who was your first?" I asked. "Dylan." She answered. "Well that makes sense. You dated him all through high school." "Not all through high school." She corrected. "Only my junior and senior years. Me, Jeanie and Eileen used to go over his house every day in the summer. He had a built-in pool in the back, and his parents used to work all day. Eileen used to like Dylan's friend Ritchie, and Jeanie, well you know Jeanie. She wasn't too picky. I think she was doing two of Dylan's friends at the same time. She was a slut, but a good friend." I had also done Jeanie, but Lisa never found out about it. "The only problem was the next door neighbor. She was Dylan's mom's best friend. She would be constantly checking in on us. But, Dylan and I figured out that she would do all of her errands for the week on Monday. She would be out for hours. So Mondays became our day. No friends just Dylan and I. We had the whole house to ourselves. Mom put me on the pill that summer. I guess she realized that Dylan and I were getting pretty serious. I remember it like it happened yesterday. He was so good looking, and I was really in love with him. I waited for the next-door neighbor to leave for the day before I would even come over. We were by the pool one Monday, making out on a blanket and things got a little ... heated. He had my bra practically off, and we were still outside. I was the one to suggest that we go inside to his room. He couldn't drag me in fast enough. I wasn't in the room two minutes and he had his bathing suit off. That was the first time I saw a penis in the daylight. It was totally erect too. I remember thinking, oh God; he's going to stick that big thing in me. I tried to just give him a blowjob, but he wasn't settling for that. I remember that he was humping me, and I still had my bottoms on. I thought he was going to tear right through the material." It was at this point that I realized that I probably made the drinks too strong. My sister was getting much too explicit, and I was getting much too excited. "The head of his cock was almost inside of me and he was taking my bathing suit with him. It felt so good though; I couldn't wait to get my bottoms off. He was trying to move the material to one side, but I wanted to be totally naked my first time. It was like trying to get a hungry bear to stop eating, when I told him to stop so that I could get my bottoms off. He then slipped them off in one big swoosh and they went sailing over his head on onto the dresser. Then he was between my legs again, and this time it was for real. He pushed inside of me real slow because I was so tight, and it hurt a little. He kept pushing into me for what seemed to be forever, but then he was pulling out and then back in again. About the third or fourth time it stopped hurting, and then it started to feel good again. It really started feeling good when he blew his load. Oh the joys of teenage sex. But, ten minutes later, we were doing it again! Oh the joys of teenage sex! This time I was on top and this time I controlled the angle and the rhythm. And this time he held off long enough for me to get my first orgasm during intercourse. I couldn't stop. I kept riding him for what seemed like ten orgasms. At least I stopped counting after ten. A half hour later, we were doing it again. You know seventeen-year-old boys; they can do it all day." "Whew. I guess." Was all I could muster as a response. I was so hot and bothered I made some excuse about being tired and excused myself to go to bed. I had to jerk off right then and there thinking about my sister getting it, but it wasn't Dylan who was giving it to her, it was my cock busting right through that bikini bottom and into her waiting pussy. About ten minutes later, while I was walking down the hall to the bathroom, I heard noises from my sister's room. I stopped in front of her door and put my ear to it silently. I couldn't be sure, but I thought I heard moans coming from her room. Maybe someone else got a little hot and bothered too. The next morning I was up and out to the bagel shop and back before Lisa came down the stairs. I was in the kitchen drinking coffee when she walked in. "Sleep well?" I asked. "Like a baby." She replied. "Must be the salt air" After breakfast I asked her. "We going to the beach?" "Not in that bathing suit." "Listen Lisa," I apologized. "...you don't have to wear it. I'll bring it back tomorrow." "No, I want to wear it. I just have to get used to wearing it. Is it OK if we just sit by the pool today?" "Yeah, no problem." It was settled. About an hour and a half later, I was sitting by the pool when she came out of the house. She was wearing the suit, but underneath a muscle shirt and gym shorts. I didn't say anything, just hello, and I just sat in my chaise reading my book. A little while later she took her t-shirt came off, and then the shorts. I pretended mot to notice and to read my book, but I couldn't keep my eyes off her body. Her beautiful large breasts were just barely contained by the triangle fabric of the bra, and I could see the outline of her pubic mound in the material of her suit. My Sister's New Bathing Suit She turned over on her stomach, and no matter how much she tried; the material was not covering that beautiful ass. After a while she just gave up, and the thin little material crept right up her crack. She turned over and looked over at me. "I'm hot." She said. "What?" I asked. "I need a drink." She explained. "Do you want me to get you one?" I offered, as I wondered how I was getting up with this large boner in my shorts. "No I got it. Do you want anything?" "OK." I said relieved. " A club soda." She then got up and walked across the patio, as I tried to keep my eyes on my book. She then did something strange. Instead of going around the bar to get the drinks, She stood tiptoe on the foot rail and bent over the top of the bar to get the two bottles of seltzer. Her right leg even bent at the knee for that classic ass shot. She was certainly getting used to wearing that suit. She walked back to me and handed me one of the soda bottles. "You know, I want to thank you for insisting that I buy this suit. I would have never had the courage to buy it on my own. No matter how much the sales girl told me I looked good in it.' She said as she took the liberty to sit on the side of my chaise lounge. "I feel good about myself in this suit. Sexy. I haven't felt that way about myself in years." She was so close and the suit covered so little. I could see every minute detail on her body; the freckles on her chest, the way her nipples delicately showed through the thin fabric, the flatness of her stomach, her hipbones glistening with sweat, the slit of her labia through the suit. "You should. You're an incredibly beautiful woman. I know that you're a mom, but you have to realize that you're much more than that. Once this whole divorce situation is over, you'll have so much to offer to the right guy." "I'm supposed to be helping you get out of your shell, and it's you who are helping me get out of mine." She bent over and gave me a big kiss on the lips. "Thanks." She got up and walked over to her chaise. She sat down on it and took a drink of her soda. She then rolled over on her stomach and continued to sun herself. She then undid the strings of her bra and lay with her head resting on her arms as I stared at the side of her breast above the chaise. Oh God, I thought. That whole nest week I felt so guilty. This was my little sister and I was having all of these "unnatural" thoughts about her. I was convinced that I was some kind of pervert and she was doing nothing to entice me. I made her wear some sex kitten bathing suit, and now I can't jerk off without thinking of her in that white string bikini. It only got worse when later in the week I was doing some laundry, and while I was folding, I found a pair of her panties mixed in with my shirts. She must have left them in the dryer by mistake and now there they were sitting in my hand. I didn't know what to do with them at first and then guiltily I looked around (as if someone was around to witness it), I brought them to my face and sniffed them. I could still smell her perfume on them. I knew what I was going to do. The same thing I've done a million times to Annie's old panties. I brought them into my bedroom, and jerked off into them. I then felt even guiltier. I was definitely some sort of sexual pervert. Friday came, and Lisa and the boys showed up for another weekend. If I felt that I was imagining things, my sister's demeanor definitely verified it. She didn't act differently; in fact she was the same old Lisa, my sister and the mother of two young boys. Saturday morning, before we went to the beach, she asked me to watch the boys while she went into town. She came back a half-hour later with a surf shop bag. She had bought the navy blue, "safe bikini." "Jimmy finally came through with some support money." Lisa said as she showed me what she bought." You don't think that I'm a bad mom for using that money to buy a new bathing suit, do you?" "Are you kidding? Who's money have you been using to feed and clothe the boys with? I asked. "Mine." She answered. "So, no, I don't think it's too frivolous for their mother to buy herself a decent suit to take her boys to the beach." "It's a lot better than that 'Mommy' suit I've been wearing." I knew what she meant by that. She was never going to wear the sexy, white bikini anymore. It was back to "Mommy Lisa." We would go to the beach in the morning, and swim in the pool in the afternoon. A beer or two, after the boys went to bed, was our only entertainment. Sunday evening we packed her car, and Lisa buckled the boys in their booster seats. She came up to the stoop where I was standing and asked if she could come out again next week. "Yes." I said nonchalantly "Bill, I know this weekend wasn't as much fun as last weekend." "What do you mean? I love having you and the boys." "Well, next weekend the boys will be with their father, and I'll be back here with my new bathing suit on." "Oh, the new blue one?" "No, the white sex kitten one. I can't wait to try it on the beach." She gave me a big kiss, and then she drove away. I was now more confused than ever. I was very busy at work that week, so Friday came, and Lisa was parking in front of my house before I knew it. "Are you hungry?" she asked right away. "I could eat." "Because I'm starving." "Well let's go eat then." We went to this little Mexican place in town, but on the walk home it started to rain. Nothing heavy, but we weren't sitting by the pool that night. I got us a couple of beers from the bar and suggested renting a movie. "Which one?" she asked. "Oh, I don't care. Whatever one you want. Let's just see what they have on the cable box." "What about that one?" She said pointing to a fairly popular one. "OK." I said. "Have you seen it before?" "No." I lied. It was kind of a chick flick, but it had some steamy sex scenes in it for an "R" rated movie. I made some popcorn, and started the movie. I lay out on the couch, and Lisa sat in the easy chair. "It's kind of cold in here" Lisa said after only a few minutes of the movie. "I'll turn down the AC." I offered. "No." She said as she got up and lay on the couch with me. "Who better to use as a hot water bottle than my big brother?" We spooned like a married couple. The movie was a little boring at first, but then the main female character meets an old flame, and the sex scenes started to come fast and furious. We both had on only t-shirts and gym shorts. So, there was no way that I could hide the boner in my pants that was pressed against the crack of her ass. "WOW. Did you know about all of the sex scenes in this movie?" Lisa asked. "No." I lied. "This could be a little embarrassing." She said as she grabbed my hand and pulled it around her. I knew she was talking about my hard on that was pressed against her. I couldn't make it go away, and I couldn't hide it. Luckily the movie ended and we just watched TV for a while. She sat up after a while and pulled the old "take the bra off while still wearing her t-shirt" trick. "You don't mind, do you? That bra was killing me." I just shook my head and then she lay back down on the couch with me. "Look at us spooning like a couple of newlyweds. But if we were newlyweds, we wouldn't be just spooning after that movie. That was a regular porno flick." I had a distinct impression that she wanted to do more than just spoon, but I couldn't be sure. I fell asleep with her in my arms. When I woke up it was just about daylight and she was still in my arms, but my right hand was where it shouldn't be. It was up her t-shirt and it was cupping her left breast. Oh my God, I panicked. I went to pull it out, but she had a death grip on my right arm. I was laying there feeling up my sister, and I couldn't move my arm. Oh my God I thought she must really think that I'm a perve. And to add insult to injury, I had a screaming morning hard on. I was dead. After about twenty minutes she loosened her grip on my arm, and I was able to slip it out without waking her. I was then able to wiggle off the couch, also without her waking, and I went to the bathroom until my hard on subsided and I could take a pee. The rain from last night was gone, and it looked like a great morning. I went out for bagels, made coffee and was sitting by the pool when she finally showed her face. Everything seemed normal. She had to have noticed me feeling her up in the middle of the night, but if she did, she didn't let on. We had breakfast and she asked if I was ready for the beach. "Give me five minutes to get on my suit." I answered. We met in the kitchen. She was wearing a t-shirt and shorts over her suit, but she stripped them off as soon as we got down to the water. As usual she looked great, and as usual I pretended to read my book, as I ogled her body. "You sure are taking a long time to finish that book." She said with a smile. "It's not too interesting." How would I know? I think I was reading the same page for two weeks. We went back to the house for lunch. I know it seems like more effort to keep going back to the house, but the house is really that close that it is easier than carrying a lot of stuff. After lunch she looked at me. "Do you mind if we don't go back to the beach, and we just sit by the pool this afternoon." "Yeah, OK." I asked. "It's just that I thought it would be fun to be at the beach in my new sex kitten suit, but there weren't any good looking guys checking me out. In fact there was one creepy guy that was creeping me out." "OK." I smiled. "It's funny how a creepy guy can creep you out." I made us a couple of drinks and we sat by the pool for a little while. Lisa was fidgety. She kept getting up and moving around. Usually the activity entailed bending over where I could look at her cleavage or stare at her ass with the bikini material making like a thong up her crack. I don't know if she was doing it on purpose, but it didn't matter. Either way, I was still getting too hot and bothered. I had to cool off somehow, so I decided to take a dip in the pool. I got up off the chaise and stripped off my shirt. Lisa looked at me and gave me a wolf whistle. "Look at that body my brother is strutting." She said smiling. "You should talk." I replied. "Where did you get these muscles?" I stopped in front of her chaise to answer, but through my dark colored sunglasses I could see her nipples and the slit of her pubic mound through her bikini. "After the funeral I would work a lot of overtime to keep busy. But at night I would still come home to an empty house. I couldn't sleep, so I started taking long walks. The walks turned into runs, the runs expanded to sit-ups and the sit-ups expanded to push-ups. Before long I was running every night, doing 200 sit-ups and 50 push-ups. It was like therapy." "You look wonderful. Not muscle bound. Just nicely toned." I flexed my right bicep in response. "Woof!" She leered. I had to get in that water. I could feel my cock getting hard, as I looked at her body, and with her talking about mine. I headed for the pool, and dove right in. The water was a little cold at first as I skimmed along the bottom to the shallow end. I reached the other side and kicked off it to head back to the deep end. I rose to the surface and swam on top until I reached that end. I then did the backstroke until I reached mid pool. I then saw Lisa get up and head toward the pool. "You coming in?" I asked. She nodded yes. She then walked to the pool stairs, walked down to the water was about mid thigh, and then dove in. She looked beautiful and thin, and the bottom of her suit pulled back with the current and showed the crack of her ass. We swam around the pool together laughing and kidding each other. She then looked down at the bra of her swimsuit. "Oh Shit!" She cried. "What?" I asked thinking something was wrong. "When this material gets wet, you can see my girls right through it!" "I hadn't noticed." I said, looking up to the sky. "You liar." She accused. "Well it doesn't really matter does it, because you had your hands all over them last night anyhow?" I cringed, and she laughed at me mockingly. She did notice me feeling up her tits in the night. How could she not? "I'm so sorry!" I said embarrassed. "I was asleep, I didn't do it consciously." "I know she said." Still smiling at me mockingly. "I can't blame you, after that movie last night. That was practically a porno flick. It got me a little worked up too." "I tried to pull my hand away, but you had a death grip on my arm." "Well, I don't mind you grabbing a little tit in your sleep, but I wasn't too sure where you were going next. On second though, I probably should have let you go. It would have saved me all that time and effort later." I cringed again, and put my hands over my eyes. "I'm so sorry." I was so embarrassed. I felt like a perve. "It's OK." She said, sensing how deeply I was embarrassed." She started to splash me, I guess to show that she was OK with it, and I splashed her back, relieved that she was OK with it. I then realized what she had just said to me. Did she really just intimate that she had masturbated this morning, and was she thinking of me when she did it? We splashed around the pool, playing grab ass like a couple of teenagers. I picked her up once or twice and lifting her by her cute little ass (with only a wisp of material between my hand and the crack of her ass) I threw her across the pool. I tickled her and she tried to tickle me back (I'm not ticklish). She tried to dunk me and I just pushed her away with one hand, and with the other I just pushed her under the water. She came up looking like a drowned rat. "OK, OK. You win!" She surrendered. "Give me your hand." I reached out, took her hand, and pulled her over to the side of the pool where I was standing in about shoulder deep water. She didn't grab for the side. She grabbed for me, and then just put her arms around my neck. Then, to my surprise, she wrapped both her legs around me. "This feels good." She said as I immediately started to get a hard on. The only thing between my throbbing member and her slit was about a millimeter of spandex and rayon. Oh great I thought. I can't even escape the frustration in the pool. "You don't mind your sister giving you a big hug? Do you?" "No, it feels good." I repeated, but this was no hug. And then, just barely noticeable, but still definitely there, I could just slightly feel my sister grinding he pussy against my swollen cock. She put her head on my shoulder, and repeated herself. "Mmm...this feels really good." And there it was again, but this time she ground in harder. There was no mistaking it. She was humping me, and this time I humped back. Her grinding kept getting just a little stronger, and I ground my cock into her crotch just a little harder. Slowly I twirled us around so that I had her back against the pool. This time she wasn't so coy. She thrust her pussy against my waiting cock and moaned. I drove my dick into her as hard as I could. She then picked her head up and started to stroke my left peck. "Billy you have such a strong chest. It's what every girl fantasizes about." She lightly scratched my erect nipple with her long nails." You don't mind me touching you like this, do you?" Just barely audible I answered. "No, it feels good." As I drove my cock into her crotch one more time. "Do you want to touch me? She purred into my ear. "Because I want you to." "Yes." I said, as I slowly moved my hand up to caress her breast though her bra. As I did this she moved one hand behind her neck, and slipped the knot out of the top string of her bra and with the other hand she slipped the knot of the back string. She then let the whole bra fall into the pool. Her breasts were as beautiful as I had imagined them to be. They were big and firm, and even though she was a 32-year-old mother of two, you couldn't see any sag in them. As slowly as I could, I reached up and cupped her tit in my hand, and ran my thumb over her beautifully erect nipple. "Billy," She pleaded. "...what are we doing?" "I don't know." I replied as we simultaneously ground our crotches against each other. "This is so wrong, but I want it." She panted. I didn't know what to say. She was right, but I didn't care. I wanted her too. "Oh God Lisa. I've thought about you for weeks." "Billy, you have to promise me that you wont fuck me. I'll do anything you want, but we can't do that. No matter how much we may want to." "Of course." I said, really meaning it. With that her hands slid down my waist and underneath my waistband. She started to push my suit off of me and down my ass. She made sure the waistband cleared my probing cock and let the suit go after it reached mid thigh. My cock was free of its prison, and I immediately jammed it up her legs to her still protected slit. She grabbed my cock with her hand, because it would have pushed the material right into her. I started to fumble with my hand to get into her panties, but it was an awkward angle. She let go with both hands as she held firmly to me with her legs. She then simultaneously undid the string bows on both side of her panties and they floated to the bottom of the pool. The impediment to my goal was gone and I slid my middle finger as far up her cunt as it would go. Lisa's head rolled back, she closed her eyes and gasped. I took a long look at her. I was now having sex with my sister, and that should be kinky enough for any man, but it was different. I wasn't just having sex with my sister, but with a beautiful woman in her own right. Her face was flawless, her breasts magnificently pouty with her new triangle tan lines. You could see just how little the sex kitten suit covered. Her stomach muscles were tight and flat and her hipbones protruded from her torso. Her pussy, shaved like the young girls do these days, was so inviting. I alternated from finger fucking her pussy, to massaging her clit. Her eyes opened wide to look at me and she bit her lip. Her hand was stroking my cock, but it slowed up as she was distracted by this new activity. "Oh God." She moaned. She was definitely getting off on it. Her hips shifted so that her pussy could meet my finger. I continued to draw imaginary circles around her clit, and it was sending her through the roof. Then I stopped and I started to finger fuck her again. Her hips slid back down her face took on a look that didn't seem as pleasured. I shifted back to her clit again, and she shoved her pussy up to meet me. "Yeah, right there." She said. "Don't stop doing that." I found what she liked. She started to take little bites out of my shoulder. She was just floating in the water with her legs lightly wrapped around my thighs. I was fingering her with my right hand as I was cupping her breast with my left hand and lightly stroking her nipple with my thumb. The combined movement was sending her into another consciousness. I could tell because she stopped stroking my cock and her body temperature was starting to rise. Her nipple became erect to my finger, and I could feel her clit become engorged. She stopped biting me because she started to lightly moan. The moans became louder and she was grinding her crotch against my hand. "Faster!" She whispered. " Don't.. stop.. doing.. that! Oh God!!" I complied with her requests, and was rewarded with some high-pitched moans. "I'm coming!" No shit I laughed to myself. She rode wave after wave of orgasm like a swimmer caught in the surf of ecstasy. And then it was done. My Sister's New Bathing Suit "OK, stop." And she pulled away from my right hand like I was hurting her. She was still regaining her consciousness when she started kissing my neck and again started stroking my cock. It was my turn. She knew just what to do. Her fingers lightly glanced over the skin of my prick. She stroked it. She didn't pull on it like it was a fire hose. Her thumb always stimulated the sensitive bottom of its tip. A hand job is teenage stuff. I wouldn't normally get my rocks off by just getting stroked, but my sister was the one doing the stroking. She is just so beautiful, but I couldn't see her wrapped all around me. "I want to see you." I asked. She leaned back with her eyes closed. She was so hot I thought that I would blow my load right then. She had the face of a model: perfect. I looked at her torso with her firm breasts floating in the water, and I could just make out the lips of her labia through the obscurity of the water. As she leaned back, her legs still wrapped around my thighs, we were in the perfect position to fuck. I would only have to grab her ass and pull her to me and I would be in her. All I could hear in my head was my sister saying. "You have to promise me that you wont fuck me." The phrase both prohibited me and urged me to do it. The, 'You have to promise me,' kept me from doing it, and the 'fuck me.' Made me want to do it more. "Is that good?" Lisa asked. "Oh, yeah. You are so beautiful." I replied. "Does it feel good?" "Yeah, you're really good at this." "The fact that I'm doing it has got to make it better? While you were fingering me, all I could think about was that you were doing it, and it drove me wild." "Uh huh." I answered as the feeling in my cock started to intensify. "You like that your sister is jerking you off, don't you.?" "Yes!" I admitted. "You like staring at your sisters tits and pussy while she jerks you off, don't you?" "Yes!" I repeated. "I want you to come." She said. That was it. The combination of my beautiful sister jerking me off, staring at he cunt, and having her talk dirty to me was just too much. I blew my load right then. I came in milky clouds that spread all over the pool. She smiled, kissed me hard on the lips and ran from the pool. She grabbed a towel from one of the chaise lounges and wrapped it around her as she headed for the back door. It was then that I became distinctly aware that I was naked in my pool. My yard is well protected with fences, bushes and trees, but someone in a second floor window might just have gotten the show of their lives. I grabbed the two suits and headed straight for the door. The rest of the afternoon Lisa hid in her room. She didn't come out and I didn't attempt to speak with her. Remorse is a terrible thing. Not that I had any remorse, but I was afraid that she did. I had to get her out of her room so we could talk about it. I knocked on her door. "Yes?" Was her reply. "Do you want to get something to eat?" "OK. When?" "Whenever you can be ready." "I can be ready in about a half an hour." "OK." I said, and sat down on the coach. Forty-five minutes later she was waking me up. "Do you still want to get something to eat?" "Yes." I replied. At dinner she was very quiet. "You OK?" I asked. "Yeah." "You feel weird?" "Shouldn't I? I just seduced my brother." She whispered. I smiled. "Seduction had nothing to do with it. Seduction implies that I wasn't a willing partner, and I was more than willing. Ever since that first time I saw you in that sex kitten suit, I wanted to do what we just did. Believe me I wanted to do more." "Don't you feel weird about what we did? Guilty?" "No. I don't see that what we did was so wrong." "We're sister and brother." She whispered again. "Do you love me?" "Yes." "And I love you. I don't see why two people who love each other can't help heal each other." "Sexually?" She asked. "Did we hurt anybody?" "No." "Did the world come to an end?" "No." "Did you enjoy it?" "Yes!" She blushed. "I liked it a lot." "So did I." I blushed back. "Listen, if I'm not hurting you or anybody else, and you're not hurting me, and we're both getting a something from it. Why should it matter?" "So you're not wierded out by this? In fact you want to continue it?" "Yes! Are you OK with that?" "I'm not sure. I really enjoyed it today, and I look at you and, physically, I want to do it again, but I still feel weird." "OK." Was all I could say. She was definitely better than when we were at the house. So I left it alone and we finished our meal. Back at the house I opened up a bottle of wine, and poured two glasses. We had a bottle of wine with dinner, so it was the logical choice. We sat at the kitchen counter on bar stools, drank the wine and made small talk. She was utterly beautiful with her shoulder length blonde hair contrasting with her tan skin. She wore a short sleeve white cotton button front shirt (with threes buttons open, so I could see her white lace demi bra) and a khaki mini-skirt. The skirt wasn't super short but one time I bent down to pick something up that she dropped I caught the up skirt of her white panties. We drank and talked for a long time. She kept touching my hand or arm every time she wanted to emphasize something she was saying. Every time she did, it sent electricity up my arm. I wanted to grab her and hold her close, but I could feel the uncertainty in the air, and so I played it nonchalant. I felt like a teenage boy with anew girl. I could feel the attraction on my part, but was unsure if it was reciprocated. She touched my hand again lightly, and then she took my hand in hers. I held her hand for a while, and then I pulled her close. I put my hands on her waist and she put her arms around my neck. I kissed her lightly on the neck. "Billy, I can't do this. You touch me, and I want you to touch me more. Then I look at you, and I say to myself, 'It's your brother, what the hell are you doing.'" "It's Ok. I wouldn't want you to do anything that you don't feel comfortable with." I let go of her waist, and she stepped back. "Why don't we just finish this wine?" I asked to break the awkward silence. "Let's" She answered in relief. We finished the wine, and made strained small talk until I excused myself because it was late. I lay in bed thinking of her. Thinking about how great she looked while we were in the pool. I thought of what she said at dinner, and back in the kitchen. It was a one-time thing, and now it's over. I told myself. I thought about masturbating, but then I knew I would be thinking of her, and I decided not to. I was just falling to sleep when I heard footsteps in the hall. I was still half asleep when I heard my door open. It was Lisa. She snuck in the doorway, and closed the door behind her. In the moonlight I could see her figure and she was wearing only a spaghetti strap tank top and panties. She slipped to the side of my bed and climbed in. She sidled up to me and called my name lightly. "Billy." "Yes." "Oh good, you're awake." She slid up to me, and we were face to face in the dark. I started to get hard as she moved her body up to mine. "Are you OK?" I asked. "Just shut up and put your hands on me." My hand slid up under her shirt and up to her chest. "Take this off." I said gesturing to her shirt. She reached down and pulled the shirt up and over her head in what seemed like a nanosecond. I engrossed myself in her bosom. I never thought I was going to see it again. They were firm and soft and round and lovely. I was loosing myself in them and her perfume. She must have felt my hard on on her leg. "You're excited already?" "You're driving me crazy." My focus shifted. There was some place that interested me more than her beautiful breast. I started kissing her stomach and then her navel. All along I had my fingers hooked into the waistband of her panties, and I was pulling them down as I went. "Billy, I don't know about that?" She said, but I wouldn't let that stop me. I kept pulling them down until they were down to her thighs. I kissed the top of her pussy as I pulled her panties past her knees. I stuck my tongue in her as I pulled them totally off. She rocked her hips toward my mouth as she let out a sigh. "Oh God." She moaned as I found her clit. My arms were under her ass, and my hands were on the small of her back so that I could pull her closer to me as I concentrated on "the little man in the boat." I alternated between sucking on it and tonguing it. I couldn't figure which one she like the best. She moaned enthusiastically either way. I was in heaven. I was eating out this beautiful woman that was my sister, and she was bucking like a bronco with pleasure. Her smell, her taste, it was all so overwhelming. I didn't want to stop. I never loved giving head. It was something I did for the girl, but this was different. I loved the sharp taste of her in my mouth. Her musky smell mixed with her perfume kept me wanting more. The fact that she was grinding her hips into my face, because she couldn't get enough, was intoxicating. It had built to a climax, and now it was coming to the end. "Billy, don't stop. Oh God don't stop." The temperature of her body started to become significantly warmer. Her back was in full arch; her breasts were thrusting for the sky. Her head was back, and her clitoris was engorged again, but this time in between my lips. I switched to tonguing it, and that put her over the edge. "Huh.... huh...huh!" was all she could utter, and then... "Stop Billy. Stop" Again like I was hurting her. So I stopped. She was just gaining consciousness again. I was crawling up her body, as I stripped my boxers off. The promise of not fucking her was long since forgotten. I definitely wanted to fuck her. More than I ever wanted to fuck anyone. Including my wife. She must have known what I had in mind, because she pushed me over on back as soon as my prick came close. She then moved up next to me and started to stroke my cock again. It was throbbing with anticipation, but not for a hand job. "Does that feel good?" "Yes." "Real good?" "Well I know what would feel better." "Billy!" She squealed in mock indignity. "You really want ME to give you a blow job?" "Yes." "You want me, your SISTER to suck your cock?" "YES" "You want your innocent little sister to take your big fat cock between these hot, red lips?" "LISA. Please don't tease me anymore!" With that she bent down and blew on the head of my cock. She then kissed it, and I rotated my hip up like she had done before, and I almost got it in her mouth. And then I got sweet relief, as she took the head of my cock in her mouth. She kept stroking the shaft of my cock with her hand as she sucked the head of my cock. The combination of stroking and sucking was more than I could stand. I looked down, but could only see the back of her head bobbing up and down. I didn't think anything could feel better than this, but I was wrong. She then slid a little farther down my body so that she could take even more of my cock in her mouth. She was taking as much of my member into her mouth as she could, because I could feel the head of my cock hit the back of her throat. Once again she switched tactics and just started licking and kissing the head of my cock. It was excruciating. She was trying to tease me, and it was working. I wanted to be back in the beautiful velvet that was her mouth. She stopped all together and returned to just stroking my shaft. This was even worse. She looked up at me at kissed my stomach once or twice. "Are you enjoying this? Are you enjoying making your baby sister do bad things to your big swollen cock with her hot swollen lips?" "Where did you learn to talk like this?" Was the only thing I could think to say? "Jimmy loved when I talked dirty to him. Do you like it?" "It's fantastic. I feel like I'm in the middle of porno film." "Big brother Billy, do you want your little sister to suck your big cock again?" "Please!" I pleaded. "But it's so big and hard. I don't think that I can fit it all in my mouth." "Lisa, please suck my cock!" She took the head of my cock in her mouth again and met her hand half way, as she sucked and stroked my cock again. "Faster." I ordered. She started stoking faster, and her sucking got harder and faster. The feeling built up and up in the head of my cock until all of the skies opened up and I was in heaven. I then exploded into her mouth. She kept stroking and sucking, and now swallowing. It was done. I was spent. I snuggled with her, and kissed her on the neck and face until we both fell asleep. The next morning I awoke with her in my arms. We were snuggled together, spooning again. We were both barely covered by a sheet and I was slowly waking and enjoying what little I could see of her naked body. My arm was around her waist, and she had her hand on my arm. I then realized that I had a morning hard on, and it was in the crack of her ass. I hadn't done it consciously, but I guess that while I was waking, I was grinding my prick between her cheeks. Lisa started to stir. "You're not thinking of sticking that in my ass, are you?" She mumbled half asleep. "I wasn't thinking about it, but I wouldn't mind." I replied. "I don't know why you men get such a thrill in that?" "I wouldn't know, Annie would never let me do it. She said it would hurt too much." "It doesn't hurt as much as most girls think." Lisa said surprisingly. "You've done it?" "Yeah, back when we were first married Jimmy convinced me to do it on his birthday. I was young and stupid, and I wanted to please my new husband." She rolled over on to her stomach, with her arms under her pillow. "Well, if you're going to do it, you better have plenty of lubricant. You're not doing it bare ass." "Really!" I squealed like a nine year old who was told he could have a new toy. "Well, you're obviously still horny (referring to my morning wood) and I've got no energy to give blowjobs. Besides you're not coming in the front door." She said almost matter-of-factly. I ran, not walked, to the bathroom and got the lube out of the medicine cabinet. I'd been using it all winter long to jerk off, but there was still plenty left. I pealed off my shorts, took a quick pee, and started to apply the stuff even as I was coming down the hall. I came into the room, and there was my sister bare ass on the bed. She had even pulled the sheet off herself for me. She was absolutely stunning, and she was actually going to let me fuck her in the ass. I couldn't believe it, but I wasn't going to give up on this opportunity. "Are you sure?" I asked as I climbed back into bed. " What the hell, it's been over a year." She sighed. "I bet you his new girlfriend isn't letting him fuck her in the ass." I just let that slide by. I was too intent on something else. I finished lubing myself, and then I found her "brown-eye" and squirted the lube up her ass. "What are you doing?" "Making sure we're both lubed up." "Jimmy never did that." I crawled between her legs, and she separated them for me. Her ass was gorgeous, especially with her tan lines making almost a heart shape for me. It took a couple of seconds for me to find her ass, but then the head of my dick found her and I pushed in. I pushed in right away, all the way to the hilt. She gave out a grunt and arched her back a little. "You OK?" I asked. "Yeah. I'm fine." She replied. "Does it hurt?" "A little, but it's OK. You really like it, don't you Billy?" "Yeah!" I said hungrily as I started to pump into her again. "You really like fucking me in the ass. Don't you?" "Yeah." I repeated. "Fuck me Billy. Fuck me in the ass!" I couldn't answer. "Your such a slut Billy. You're fucking your own sister in the ass. Does it feel good? Does it feel good to stick your big cock in your little sister's ass." She didn't need to do this. Fucking my sister in that beautiful heart shaped ass of hers would have been enough for me, but it definitely made it better. I started to pump harder. "Are you going to come in me? Are you going to come in my ass? "Yes." I grunted. "I want you to. I want you to come in me Billy." There was no turning back now. I was pumping her even harder. The climax was building in the head of my penis. I closed my eyes and started to come. "I love you Lisa." "I love you too." She consoled me. I didn't even pump any more. I just arch my back and enjoyed the feeling of coming, and coming in her. Finished, I pulled out of her and rolled on my back. She turned on her side facing me and just smiled. "Happy?" She asked. "Very happy." I replied. She kissed me on the lips and got out of bed. "I'm going to take a shower." She announced. I just smiled as I watched her ass trot out of the room. The rest of the day went so fast. It was four O'clock and she was walking out the door before I knew it. "I don't want you to go." "I have to, Jimmy's dropping the kids off at 5:00." "I know." I reluctantly agreed. "Beside, you owe me." "What?" "You got an extra one this morning. Remember?" "Right." I agreed. "I owe you." She gave me a kiss and jumped into her car. "Remember you owe me! She yelled out the window, as she drove away. That week at work was a bear, and the weekend was no better. We had a major proposal due on Monday so I worked late every night, and I also needed to work on Saturday. I made my apologies to Lisa, but I really didn't see them that weekend. "Its OK." She assured me. "We have the pool and the beach. The boys love having you around, but they're little boys. They only miss you until something else catches their attention." I saw them Friday and Saturday nights, but I was so exhausted that I practically fell asleep right after dinner. "I feel like I'm married again." She kidded me Saturday night as she rousted me off the couch to go to bed and sleep. "I'm sorry." I mumbled as I walked to my room. "Its OK. Besides, if you were around when the boys were here, it would be too much of a temptation." That made me feel good, and I thought about her beautiful body while I jerked off, and then I went to sleep,. The beginning of the next week was busy too, but by midweek things started to calm down. On Thursday I only had to stay until six, and on Friday I actually left early. I used the time to buy groceries, and clean the house before Lisa was scheduled to arrive at seven. While I was cleaning, I started to go through some of Annie's things. I went through her closet and her dresser. Annie was a shop-a-holic. She had thousands of dollars worth of clothes. Many of the things (including lingerie) still had the tags still on it. I thought about donating it, but then I thought about Lisa. Maybe she could use some of the stuff. When she came into the door, I was actually excited to see her. Not like being excited to see a friend you hadn't seen in a while, but sexually excited. She must have felt the same way, because she gave me a big hug and kiss after she put down her bag. "Its good to see you." I said. "Its good to see you too." She smiled with her eyes. "Want a beer?" "I'd love a beer!" We had a couple of beers and talked. When she talked, she would touch my hand or arm. It was intoxicating. "Listen." I said after I got us our third round. "I was going through Annie's things today." Lisa looked at me puzzled. "You know, her closet and dresser. I was wondering if you would want anything before I donated it." "She used to have such beautiful things." She squealed with delight.
