Date: Sat, 07 Aug 2004 22:36:23 +0100 From: X Subject: Her Brother, part 3 THE STORY SO FAR... Since my girlfriend Steph found out about my bisexual fantasies, we've had two amazing threesomes... with her brother. After the latest time, when Jamie shot his cum over both of us and Steph licked her brother's cock clean, she dropped the bombshell that she wanted to watch me fuck my sister, Katie... ~ We didn't talk about what Steph had said the next day, or even the day after. Maybe it was the way I reacted to it, or maybe Steph just felt she'd crossed too many lines lately. It didn't matter either way, because less than a week later Steph and I went down to the beach to take advantage of the summer sun and the warm water... We dropped our towels and headed into the sea, me in a pair of shorts and Steph in a small black bikini that did a lot to accentuate her curves. As we splashed and grabbed each other, it all started to have an effect on me, and it wasn't long before Steph noticed. "Mmmm," she purred in my ear. "Getting a little excited?" She slipped her hand into my shorts and wrapped her fingers around my cock, tugging and squeezing gently. I just smiled and nodded back, then I leant in to kiss her. Just as my lips touched hers, she swam out of my grip and tutted at me mockingly. "Sorry, you'll just have to wait until we get home." Then she winked, turned, and walked out of the sea, her ass swaying provocatively as she bent down to pick up her towel. I was left standing waist deep in water, watching the beach, wondering if I could make it to Steph without anyone spotting the raging erection in my shorts. The beach was pretty quiet, so I adjusted myself as well as I could and made a run for it, coming up behind her and grabbing her around the waist, pressing my cock against her ass. She leaned back, reaching her arm up over her head and pressing her hand against the back of my neck as I leaned in to kiss hers. She twisted her hips, rubbing my cock with her ass. After a few seconds, she hmmm'd thoughtfully at something. I kept kissing wetly along her neck, stopping for a moment to whisper, "What?" in her ear. "Isn't that... Katie?" She moved her head away and nodded in the direction, but she continued bumping her ass against me, keeping me hard. I looked up and saw a figure in the distance - a slim girl with slim hips and long blonde hair, walking along the beach in a tiny sky blue bikini, looking a little younger than my sister's 17 years. I squinted, trying to make out her face, until I knew it was Katie. "Yeah," I said slowly. "I think it is." Then I looked down at Steph to see a another one of her strange little smiles on her face. I frowned. "What are you planning...?" I never got to find out, because Steph turned away from me and waved her arm high over her head. "Katie!" she called, and the girl turned and shaded her eyes from the sun as she squinted at us. Then her own arm went up in return and she started making her way toward us. "What are you doing?!" I whispered to Steph urgently, pushing myself away from her, dislodging my cock from between her asscheeks, but keeping my hands on her waist to keep her between me and my sister. "Hi guys!" called Katie, once she was within talking distance. We all said our hellos, then Steph asked Katie if she was here by herself. Katie nodded her head, shaking her hair over her face, then brushing it away again with her hand. "Yeah, just came for a quick swim..." she trailed off. Steph turned to look at me quickly, winking at me while her face was hidden from Katie. Then she turned back and said, "Well, you can hang out with us, right?" She turned back to me, this time for Katie's benefit. "Uh, yeah, of course," I stammered, cursing myself for letting Steph get me so worked up like this. All I could think about was Steph telling me she wanted to see me fuck Katie, but with my sister right in front of me I struggled not to imagine it. Somehow I managed to will my erection down a little, but then Katie smiled at us, dropped her bag on the sand and bent over away from us to get out her towel. Steph turned and gave me another look, this time of wide eyed excitement, then she turned back and openly stared at Katie's ass as her hand felt its way backwards and grabbed my softening shaft through my shorts. My cock immediately leapt back to full attention, and I couldn't help letting out a gasp. Katie immediately looked around, but Steph was quicker, moving her hand up to my stomach as if she was just casually brushing her hand against me. I quickly turned and made myself busy with my towel on the sand before (I hoped) Katie could notice my arousal. We all made ourselves comfortable on the sand - at least the girls did. I had to lie on my front to hide an erection that wasn't ready to quit. I turned my head and looked first at Steph, then past her at Katie. Her long blonde hair was splashed across the sand around her head, and as my gaze went to her face, she licked her dry lips slowly. For a moment I imagined she was teasing me, but her eyes were shut tight against the strong sun. As my eyes continued down, to her neck and the top of chest, I caught a movement in the corner of my eye and found Steph looking at me with one half-open eye. As we looked at each other the corners of her mouth crept up into a smile. Then her lips parted slowly and she mouthed a single word: "Look." I nodded slowly, and carefully raised myself up on my elbows. Steph kept her eyes on me, and I took a moment to look at her curvaceous body. Then I took a breath and turned my attention back to my sister. She had leant her head back to keep the sun out of her eyes. I followed the line of her chin, down to the smooth skin of the top of her chest. I swallowed, feeling my face turn red under Steph's gaze, and took my first deliberate look at my sister's breasts. Her bikini was little more than two small triangles held together by strings, and laying on her back there was perhaps more flesh on display than she knew. As unendowed as she was, her gentle curves were obvious, and alluring. I licked my lips, not even realising I'd done it until I saw Steph stifling a giggle. Just then Katie raised a hand to scratch her nose, and in fear of being caught peeking I lay back down. Steph had her eyes on me the whole time, and when I looked back into them I saw she was already planning something. She stretched, cat-like, then rolled, towards me, onto her front, deliberately giving me a great view of her cleavage as she did so. Once she was settled on her front she reached back with her hands and started undoing her bikini top. At the same time she looked at me and said, loud enough for Katie to hear, "Do my back?" I looked at her and blinked, momentarily stumped by what she meant until she nodded in the direction of a bottle of suncream we'd brought with us. "Oh, sure," I mumbled. I picked up the bottle and started getting up on my knees until I saw that Katie had cracked open one eye to see what was going on. A surreptitious glance down told me that my hard cock was still just showing through my shorts, but I knew what Steph was expecting of me. And besides, Katie would still have to look right at my crotch to see anything, and that would say more about her than me... wouldn't it? I shook my head clear of speculations and decided to get on with it. I shuffled toward Steph, then lifted one leg over her, straddling her ass, steadying myself with one hand on the small of her back. I popped the top off the suncream bottle, then I had an idea. I held the bottle towards Katie and said, "Want some, Katie?" Katie's head snapped up at my voice, as if I'd caught her watching us when she shouldn't. "Uh, sure," she said, when she saw the suncream, and she pushed herself up to sit cross-legged next to me, holding out her cupped hands. Steph turned her head towards Katie and rested her cheek on the back of her hand. I had to lean forward a little to hold the bottle over Katie's hands, and doing that pressed the base of my hard shaft between Steph's asscheeks. I squeezed the bottle, and I gulped as I considered the imagery; here I was, squeezing something white and sticky into my sister's hands. I think Steph was thinking the same thing, because she gently rocked her hips underneath me, rubbing her ass against my balls and keeping me hard - as if I needed any help. Steph's movement made me tighten my grip on the suncream bottle, and it fired out a blob of suncream past Katie's hands and onto her thigh. My eyes went to her face, and I saw her look down - but something told me she hadn't been looking quite at her hands before. Had she been looking somewhere a little lower, in front of her? I'm sure I flushed red at the thought of her eyes on my hard cock, but I covered it with an "oops" and hoped she thought my little accident with the suncream was the only reason I looked embarrassed. Katie giggled and I felt Steph trembling between my legs with supressed laughter. "It'll all end up on me anyway," said Katie philosophically, as she rubbed the cream into her leg with a single finger. I watched her for just a second longer than was polite before turning my attention, not entirely completely, to Steph's back. I squirted suncream up Steph's back, leaving a long white trail that, in my current horny mood, looked all too familiar. I wedged the bottle into the sand between Steph and Katie, using the action to look at my sister's shapely ass while she sat up next to Steph, leaning forward and running her hands down her slim outstretched legs. I leant forward and began to rub the cream slowly into Steph's skin. My hands pushed up her sides, causing her to suck in breath as my fingers brushed the sides of her breasts. I glanced back to check that Katie wasn't looking, then forced my hands underneath Steph, who pushed up on her elbows to let me cup her breasts. I felt her nipples pressing into my palms before I released her. My hands moved to her shoulders and while I massaged them, I looked back at my sister. From my position I couldn't see much more than her back, but as I watched I saw her bring her hands up over her chest, and then she unmistakably pushed first one hand, and then the other, underneath each triangle of her bikini, touching her own breasts, covering them with suncream while I watched. When she started rubbing her hands together, I knew she was finished. As she started to lie back down on the sand, I lifted my leg back over Steph and sat down on my own towel, this time deliberately trying to let Katie see the hard bulge in my shorts. She didn't disappoint me - before she closed them, her eyes were drawn to the movement and this time I was sure she saw everything. A shudder of excitement passed through me, but I kept my cool and lay down as slowly as I could. After a while of baking in the sun I started to feel cooler. I put a hand over my eyes and looked up to see that clouds had rolled in. I opened my mouth to tell Steph, but stopped myself when I looked and saw that she had rolled onto her back, with her bare breasts shamelessly on display. Katie had heard me move and had sat up on her elbows to look at me, apparently ignoring Steph's nudity completely, so I quickly recovered my thoughts. "Looks like we should get moving." Steph finally opened her eyes and sighed, "I think you're right." Then she held out her hands and I pulled her to her feet. Katie hopped up lithely and we all started getting our things together. As Steph moved around, it was all I could do to drag my eyes away from her softly jiggling breasts. She stuffed her bikini top in to a bag and pulled out a t-shirt, pulling it on slowly. I couldn't help taking another look, and as I stood and watch her nipples disappear under the t-shirt, I looked past her and found myself looking into the eyes of Katie, kneeling to put her towel into her bag. She looked away quickly and suddenly made herself look a lot busier. We made our way back to the car and climbed in, Steph in the passenger seat next to me and Katie sitting behind us, still wearing nothing more than her bikini. If she had brought any other clothes with her, I hadn't seen them. As I started the car Steph leaned around her seat. "Do you want to come back to the apartment Katie?" she asked innocently. Katie glanced momentarily at my reflection in the rear view mirror. "Uh, sure," she said, but she didn't quite sound it. Steph faced forward. Only I could see the smile creeping up at the corner of her mouth. "You don't need to be back home any time soon, do you?" It was a question, but not much of one the way she said it. "And we could all probably use a shower." I glanced back at Katie. She seemed calm enough, one arm across her chest, holding her other arm in her hand. "Yeah, get this suncream off me before I get changed." And so the car journey continued, idle chat punctuated by not-uncomfortable silences. Eventually I pulled up outside the apartment and we all bundled out of the car and inside. Katie went in first, sliding past me in the narrow corridor while I held the door open. Steph went next, biting her lip in a sly smile and grabbing at my crotch, giving my cock a lingering squeeze that made it jump in response. For a moment I started to panic at what she could be planning, but we were both willing partners in this and I trusted her to do the right thing. Would "the right thing" end with me sliding my cock into my sister's young, tight pussy? By the time I closed the door behind me my cock was thickening in my shorts, but not yet enough to be on show. Katie had dropped her bag on the couch, but she was still lingering on her feet as if waiting for permission to sit. She'd always been too polite, and our family were always affectionately teasing her about it, usually by calling her "Princess". Steph was near the door to the bedroom, and she crossed her arms under her breasts as she spoke to Katie. "Still want to use the shower Katie?" she said, unfurling one arm and gesturing behind her, into the bedroom and through to the bathroom. Katie glanced from Steph, to me, and back to Steph. "Oh, no," she said, with a wave of her hand, "you guys go first, I can wait." Steph shook her head and smiled, as if to say she wouldn't hear of it. "It's a big enough shower, and we just need a quick rinse." I marvelled at the way she could talk that way and make it sound like the most natural thing in the world. Before waiting for an answer she spun on her heels and headed through to the bathroom. Katie turned to me and I saw a look of confusion flash on her face. I just did my best noncommital shrug and headed off after Steph. I walked slowly, and after a few steps I heard Katie's bare feet padding softly on the carpet as she followed me. Steph already had the water on, leaning in to play with the taps, her t-shirt already spotted with water. She turned to us, shaking water from her hand. "Go ahead, it's ready," she said, impatiently, so I stepped into the shower, moving under the water to the back of the stall. As I turned around and started to brush the water over my chest, I watched Katie entering carefully, her hands gripping the sides of the doorway, pulling herself inside. The shower was large, with the shower head directly overhead in the middle, so it was by no means a tight squeeze, but I could feel her closeness as she leant her head back and let the water cascade down her neck and chest. She stepped back and began to run her long slim fingers over her skin, wiping suncream and sand off into the water. Then her head dropped, her eyes opened and for a moment we held each other's gaze. A movement at the shower door distracted both of us. Steph was standing in the door, watching both of us. Without saying a word, she crossed her hands over her waist, gripping the bottom of her t-shirt. Slowly, so slowly that Katie would have to realise she was putting on a show, Steph lifted her shirt. She lifted her breasts with her hands too, until they fell into our view, bouncing firmly. I could tell from the stiffness of her nipples that she was as aroused as I was quickly becoming, but at least Katie might dismiss that as natural. Unfortunately she wouldn't think the same of the hard-on I was quickly developing under my shorts. Katie and I moved to make room for Steph, so we were all standing in a circle around the water. I could see that Steph was showing off, lifting her arms up as she pulled her fingers through her hair, pushing out her chest so just her breasts caught the shower's stream. When I looked at Katie I could see her doing her best to look casual, but also trying very hard not to look at any part of me or Steph. I was just starting to wonder how much longer we could all stay in the shower, when Katie crossed one ankle over the other and bent forward quickly at the waist, spreading her hands down her long legs. As she stood, I was ready to take advantage of the view down her bikini top. I looked away before she could notice, but it didn't go unmissed by Steph, who managed to "accidentally" elbow me in the ribs. She apologised genuinely, then turned her back to me and pulled her hair over her shoulder, offering her back to me. I took the hint right away, pressing my palms and fingertips into her back, causing her to sigh in pleasure. I glanced quickly at Katie, who was staring intently at her feet. I think Steph noticed it too, because the next thing she did was to moan, "That's just perfect..." as I pressed my thumbs into the small of her back. Her actions were as arousing to me as they were embarrassing to Katie, and I was thankful that my little sister wasn't looking our way, because she would have seen my cock making a tent out of my shorts. Katie turned her back to hide her blushes, but also to hide something else. While my hands worked on Steph, my eyes stayed fixed on my little sister as she pushed her hands underneath her bikini top, letting the water wash over her breasts. She was standing almost side by side with Steph, who was also watching Katie from the corner of her eye. "You might as well just take it off Katie," said Steph, startling Katie and me. Katie looked up at Steph blankly. I stepped closer to Steph, partly to reassure myself that she knew what she was doing, and partly to let her feel the tip of my hard cock against her ass. She wriggled herself back against memjust as Katie glanced back at me. I did my best to look uninterested, to let her know she was safe with us. It must have worked, because Steph turned her back to us, bowed her head, and reached up to her neck to untie her bikini top. Steph bent forward a little, pushing her asscheeks around my shaft. I slid my hands over her hips, holding her tight against me, as we both watched intently as Katie held one arm across her chest, holding her bikini top on while her other hand slid up behind her back to untie the last knot. Steph ran her hands up her flat stomach and cupped her breasts, and I watched over her shoulder as she pressed her thumbs against her nipples. Katie took half a step back under the water, letting it cascade through her long hair and down her back. So slowly that I started to wonder if she was nervous or if she was deliberately teasing me, she lowered her arms, letting her top fall to the shower floor with a splash by her foot. She looked down, and I saw her face in profile, and my cock throbbed in my shorts at the fact that my sister was standing wet and topless in front of me. Steph spun around in my arms, and for a moment she pressed her breasts against my chest. I felt her nipples tracing across my skin as she stretched to kiss me, pushing her tongue between my lips. It wasn't the world's most passionate kiss, but she didn't stop until Katie turned, her arm covering her breasts. As Steph broke her kiss, I couldn't help looking at Katie's body first, with her a face a close second, and I blushed deeply. Steph rescued us from awkward silence by saying loudly, "Turn around so I can do your back." I started to turn my back on her but she reached out and stopped me as I was facing Katie. A quick glance down confirmed that there was no way my little sister could miss the tent that her brother's cock was making in his shorts. Steph moved up beside me, one hand on my waist to steady herself against me while the other massaged up and down my back. After perhaps half a minute it all began to feel normal again. My eyes never strayed from Katie for too long while I patiently let Steph rub me down, and I saw her openly staring at my cock more than once, but when our eyes met there was no shame. When Katie started to drop the arm that was covering her breasts, it was a moment before I realised what was happening. Her fingers were spreading open, and beneath them I saw my first glimpse (since she was a kid, anyway) of my sister's dark nipples. Before her arm dropped to her side, she pushed it up under her breasts, cupping them before me, accentuating their pert youthfulness. Steph squirmed against me, and I lifted my arm around her shoulders. She pressed herself against me, my side between her breasts. I looked down and saw one hard nipple, knowing it's twin was behind my back. I flicked my eyes up to see that Katie's eyes had followed my own, and I smiled reassuringly at her. She smiled back. Steph was watching all of this intently, and now she was going to make the boldest move of the day. She leant forward, craning her neck to look down. "Oh look," she said, almost parentally, "he's got himself all excited." Her free hand, which had been resting at my waist, slid across my stomach and over the front of my shorts, her fingers squeezing my shaft, making its outline clear. I stiffened - at least, those parts of me that weren't already. Steph lifted her knee against the backs of my legs, forcing me to arch my back to keep my balance, making my hardness even more obvious. I looked nervously at Katie to see her reaction. Her mouth was open. Her chest was moving with quick breaths. I knew she knew I was watching her, but her eyes seemed glued to Steph's hand and to what it was showing her. Once again Steph broke the silence. "I guess you really are a tit man," she said. It was a comment aimed at me, but she made sure it was for Katie's ears too. Her fingers stroked my shaft steadily through my shorts. "Poor thing... I think I should take care of it, as it's partly my fault." She stressed the word "partly" just as she looked up at Katie. I knew what she meant. My half-naked sister was turning me on, and by now she must know it herself. "Yes, just have to take care of it..." Steph repeated, whispering. Her hand slid back up to my stomach, and I took a deep breath. Her fingers pressed against my flesh, slipping into my shorts. I felt her warm, experienced fingers wrapping around my shaft. She felt my cock pulse and grinned up at me. She pulled her hand outward, stretching my shorts until they snapped down around her wrist. I gasped in a ragged breath as my sister got her first look at my hard cock. If Katie had been still before, now she was like a statue. Her wide eyes were locked on the flared red tip of my cock, Steph's squeezing fingers making it throb visibly. Katie's hands were pressed flat against her thighs. Her legs were locked across each other at the ankles, one foot flat on the floor, the other on her toes. The only movement I could discern was the rapid rise and fall of my sister's beautiful breasts as she breathed heavily. "Mmm," Steph cooed in my ear, "lovely and hard..." She looked at Katie, then back at me. "I think Katie likes looking at your beautiful hard cock." Katie's eyes darted up to Steph, and for a moment I thought the spell had been broken and Katie was going to run from the stall. But instead Katie looked away, at the walls, at the floor, her face flushed. Steph's hand started a slow stroke up and down my cock as she spoke. "It's okay Katie," she said, like a parent comforting a child, "you can look." Once again Katie looked at Steph, then at me, for a long few seconds. Finally, she swallowed and, her breasts still heaving, allowed herself the guilty pleasure of watching her brother being jerked off. With Katie back in the game, Steph began her real assault on my cock. Her hand moved quicker, squeezing with every pull. I saw her lick her lips, and she began to speak to me. "Doesn't she have lovely little tits?" she whispered, but loud enough for both of us. I glanced up to Katie's face, but she was showing no sign of having heard. I nodded. "Mmm, I thought so," Steph continued. "I bet you'd love to touch them... play with them... lick them." I moaned in response, pushing with my hips, trying to fuck Steph's fingers. "I bet you'd love her to touch you too. Her fingers, running up and down your shaft..." She demonstrated, lightly brushing her fingertips over every inch of my cock, teasing my throbbing tip with her thumb, wiping a drop of precum into it. I was getting close, and Steph knew it. Behind me, her hand started tugging at my shorts, exposing the full length of my shaft and my balls roughly. "Yeah," she teased, "I can feel it... are you going to cum for your sister?" "Yes!" I gasped, not even waiting to see Katie's reaction. Steph tutted. "Now now, we should check with Katie..." She turned her head up to face Katie and whispered. "Do you want to watch your brother cum for you, Katie?" I tore my eyes away from Katie's breasts. Her eyes came up to meet mine, and for a moment she stopped breathing and swallowed. When she opened her mouth again, it felt like time stopped. Steph and I held our breaths. Her hand paused on my cock. Katie took a deep breath. "Yes," she whispered. "Oooh yeah!" Steph whispered in responses. Her hand jumped into life, stroking my cock furiously. Her other hand pushed at the small of my back, and I stumbled forward. Katie took a step back against the wall of the shower as I put my hand out past her shoulder to support myself against the wall. I looked up and stared, through a curtain a water flowing over my face, into her wide, excited eyes. I felt my balls contract up into my body, ready to fire. "I'm cumming," I whispered, and right then Steph slid her hand between my asscheeks and shoved her finger into my ass. I gasped, my ass clenching down around her finger, my cock throbbing even harder. "Grab his balls!" Steph whispered urgently to Katie, and a moment later I felt my little sister close her fingers around my balls. "Oh fuck... I'm cumming!" I whispered again, and then I grunted out loud as the tip of my cock spat a short blast of cum against Katie's stomach. Steph's finger twisted in my ass, and a second later a massive blast of cum fired up over Katie's body, splashing in a line of white between her breasts. Katie squealed, and her fingers squeezed my balls. Her other hand flew up between her breasts, spreading my cum between her fingers, even as my cock sprayed more across her arm. Then, to everyone's surprise, she started to giggle uncontrollably. By now my orgasm had flagged only a little, and Steph was still jerking cum out of my cock and over Katie's thighs, strings of white over the blue of her bikini bottoms. My orgasm finally faded along with my hard-on, but my cock was still thick in Steph's hand. She was grinning wickedly as she squeezed the last drops of cum out of my shaft, deliberately aiming them at Katie's feet. Katie was still giggling, squealing each time Steph hit her target. When Steph had had her fun, she stepped back and coughed deliberately. "Well," she said, smiling, "I guess we have to wash all that off now." She held up her hand, spreading her fingers and showing off the strings of cum that had dripped there. Katied giggled again, and I couldn't help laughing with her, as I stood under the shower with my shorts around my knees. I pushed them down and kicked them off on top of Katie's bikini top, then stepped back out of the water. Steph and Katie both stepped forward, letting the water splash down over their breasts. I stood and watched by the door to the stall as my sister and my girlfriend washed away the traces of my cum. Katie was still spluttering with giggles, Steph smiling broadly as their hands touched accidentally under the water. As the last traces of my cum were washed down Katie's legs, I stepped out of the shower. I patted myself dry with a towel and almost wrapped it around my waist automatically, but I decided to see how long the taboo-breaking could continue. I had to pee, and after a quick glance to check that Steph and Katie were still showering, I stepped in front of the toilet and started to relieve myself. I knew they would hear, and a few seconds later I looked over my shoulder as Steph, quickly followed by Katie, stepped out of the shower. Steph gave me an inscrutable look and a smile, while Katie decided it was best to pretend I wasn't there. I shook myself dry and turned around to Steph, slipping our arms around each other's waists. We both watched while Katie, apparently oblivious, towelled herself down. Then she picked up the bikini top she had carried with her from the shower and quickly tied it around herself, restoring her modesty. Steph looked up at me, and I could see what she was thinking. The game was over, for now. I nodded, and she picked up my towel and wrapped it around my waist. TO BE CONTINUED...
