Cindy Tyler felt good as she pulled into her f****y's driveway. She attended UC San Diego School of Medicine, and she enjoyed living on her own, but as corny as the saying was, there was no place like home, and currently, she was back in Los Angeles for spring break.

"Mom, Dad!" she called as she walked in the door. The house was fairly small, so her mother wasn't far away, and she leaned out from the kitchen to greet her daughter.

"Hi, honey!" she said with a warm smile. "Your father's still at work; hang on a second while I get Ryan to help with your bags. RYAN!" Cindy winced at the volume of her mother's voice, but fortunately she didn't have to call again. There was the sound of a door being opened, and a moment later her b*****r emerged from the hallway to her right.

"Hey, Cindy," Ryan said with a small smile. He was always like that: quiet and polite. Cindy grinned and wrapped him in a tight hug, finding herself vaguely surprised at how big he was getting. At 23, Cindy was older than Ryan by five years, so he was still about an inch shorter than she was, but he was certainly not the boy she'd left at home five years ago. Ryan was thin, not overly muscular but fit, courtesy of his habit of running along the beach, and his sandy blonde hair was cut short. Blonde hair was something he shared with her (hers hung down to her shoulders, but hey, it was the same color), but other traits were very different. Cindy had brown eyes, like her parents, but Ryan had gotten the recessive genes from Mom and Dad (homozygous recessive was the technical term) and he had bright blue eyes.

"Oh! Sorry," Cindy said with a little laugh, as she realized that she'd been holding on to her baby b*****r a bit too long. "Come on out. My stuff's in the trunk. Don't worry; I won't make you carry too much." Ryan nodded, but hung back a bit, reaching down and adjusting his pants a little. As they walked out to the car, Cindy looked back at him and smiled reassuringly. "It's okay," she said softly, making sure the sound didn't carry back to their mother. "You know, your...reaction there." Ryan blushed.

"I'm sorry," he replied. "It kinda does that on its own. I shouldn't—"

"Hey," she said, shaking her head, "I said it was okay." As she pulled out her first back, which she knew contained underwear and bathing suits, a mischievous smile tugged at the corners of her lips. "Hey, Ryan, you're on spring break too, right?"

"Yeah," he nodded.

"Well, after we get this stuff into my room, how about we change into our suits and go down to the beach?"


It was a good day for relaxing on the beach, as luck would have it. It was sunny, and the sea breeze kept it from getting too hot. Ryan was swimming in the ocean while Cindy lay on the beach towel. Her medical studies kept her indoors most of the time, so now was a good time to work on her tan.

Who knows? I might even catch the eye of some local stud. Cindy hadn't been on a date since she broke up with her boyfriend two months ago. She knew she looked good, with her long blonde hair, clear skin and inviting figure. She wasn't as lean as her b*****r, but the body fat she had served to accentuate her curves, giving her full hips, a smooth (if not completely flat) stomach, sleek thighs she knew men loved, and generous C-cup breasts. No, it wasn't her appearance, she had just concentrated very hard on her studies since the break up, and her love life (and, subsequently, her sex life) had fallen by the wayside.

Not today, though, she thought. The dark green bikini she was wearing now showed off her voluptuous body to any who wished to look, and hopefully someone would.

At the sound of splashing, Cindy propped herself up on her elbows to look at Ryan as he left the sea and came to sit on the beach towel next to her. He was breathing hard, and Cindy couldn't help noticing beads of seawater sliding down his tautly muscled chest and abs.

"Why are you out of breath?" she asked. "You only ran like fifteen feet."

"It was cool, Cindy," Ryan responded, grinning like a little k**. "I actually had a shark swim around me out there." Cindy raised an eyebrow.

"Bullshit," she said. "You wouldn't just be excited; you'd be terrified and yelling for everyone to get out of the water."

"Well, I might have if the shark was more than two feet long," he said, chuckling. "I think it was just a dogfish."

"Well," Cindy said. "When you tell your friends about this, that shark needs to be at least ten feet long."

"Hell, why not go for twenty?" Ryan joked. The thought had them both giggling, but after a moment the laughter faded and the siblings found themselves simply gazing at each other. Cindy was really taken by how handsome her b*****r was, about how his bronzed skin looked so smooth, about how the seawater on his body might taste under her tongue...

Oh man, Cindy thought, I REALLY need to get laid. I'm fantasizing about my little b*****r, for God's sake! Sure, she had wanted to tease him a little after his involuntary erection back at the house, but she hadn't anticipated her own reaction. Surfacing from her thoughts, Cindy realized that as she had turned onto her side to face Ryan, and he had a good view of the shadowed curves of her breasts. Judging by the look on his face, he had most definitely noticed, and there was a growing bulge in his swim trunks.

"So," she said, attempting to get back to something more normal, "Did you ever end up going out with what's her name, Bethany?" The last time they'd spoken on the phone, Ryan had been working up the nerve to ask out a girl from school he was interested in.

"No," he said, his face falling. "I tried asking her out, but I sounded like such an idiot, and she said she wasn't interested." Cindy gave him a soft, sympathetic smile.

"So it was nerves? Come on, Ryan, you're a great guy. You're nice, handsome and intelligent. Any girl would be lucky to get you." Quickly scanning the beach, Cindy spotted a pair of girls about Ryan's age, a brunette and a redhead, heading in their general direction. "Try and talk to one of them," she said. "I want to see how you do." Ryan looked anxious, but he stood up and walked over to the pair. She could see him walk up to the girls, who smiled and greeted him. He blushed and fidgeted a little, and Cindy could see him say something, but couldn't hear it. There were what looked like several abortive attempts at a sentence, but after that, Ryan smiled, embarrassed, and waved goodbye to the two girls. For their part, the girls seemed amused, giggling a little as they waved at him and walked away. Finally, Ryan sat back down next to his s****r.

"I'm sorry," he said, blushing. "I said hi, but then I couldn't think of anything. I just...I don't know. I just can't talk to girls."

"You can talk to me," Cindy reassured him, reaching out and squeezing his shoulder. "I mean, you were just talking to me about the little shark you saw." Ryan gave a frustrated sigh.

"It's different, Cindy. You're my big s****r; I can always talk to you. I mean, you'd mess with me sometimes when we were little, but I knew you wouldn't really make fun of me or anything." He chuckled bitterly. "If I could date you things would be perfect." Cindy rubbed her hand along his shoulder, but there wasn't anything else she could say. After a while, they rolled up the towel, threw their sunscreen into a bag and started to head back to where her car was parked.

If I could date you things would be perfect.

It was i*****l and, as Cindy reminded herself, just plain wrong, but Ryan's bitter joke had put the idea in her head, and like a seed, over the next few days that idea would start to take root.


"Your father's construction firm has a job in Dallas," Cindy's mother said. "He asked if I wanted to go with him, and if you and Ryan don't mind, I'd really like to."

"Oh, it's no problem for me," Cindy replied, "and I'm sure Ryan will be fine with it. How long are you going to be gone?"

"We'll be back at the end of the week. Are you sure you two won't be bored by yourselves?"

"Don't worry, Mom," Cindy answered. "You can check with Ryan, but I'll be fine here."

"Alright, then," her mother said, visibly relieved that she wasn't abandoning her c***dren. "Your father and I will be leaving tomorrow."


It had been Friday when Ryan had made his joke about dating his s****r. On Monday, Cindy had found out about her parents' trip. By Tuesday evening, as she and Ryan drove back home from seeing their parents off at the airport, the seed that had been planted in Cindy's mind had grown into something much bigger. By now, she had a plan.

"Hey, Ryan," she said casually, "after we get home, do you want to get changed and go on a date with me?" Ryan started, and Cindy chuckled, grateful that he wasn't the one driving the car.

"W-what do you mean?" he asked, swallowing.

"Well, you seem to have trouble with your nerves around girls, but you can talk to me without any trouble, right? So why don't we go on a date, and I can give you a lesson on how to act around other girls?" Ryan thought about it for a moment, and then answered with obvious excitement.

"Okay, that sounds great!" As the siblings pulled up to a red light, Cindy looked over at her b*****r.

"Alright," she said, "ask me out."

"Uh, okay. Would you...uh, if you're not doing anything..." Ryan was obviously nervous, so Cindy reached over and squeezed his shoulder.

"Remember," she said. "I'm not some girl from school; I'm your big s****r. I won't laugh at you or make fun of you for being nervous." Ryan smiled, relaxing noticeably.

"Thanks, Cindy." He took a deep breath, blew it out, and then tried again. "Cindy, would you like to have dinner with me?" Cindy gave him a warm smile.

"I would love to."

When the two got home, Cindy ran to her room and changed into her favorite sundress. It was covered in a red and orange floral pattern, and the plunging neckline showed a generous amount of cleavage. Coming out of her room, she found Ryan waiting in the front room, dressed in khaki pants and a black button down shirt, and the look he gave as he took in her dress was enough to heat her flesh, and Cindy felt herself moistening between her thighs.

"Alright, baby b*****r, let's go for our date."


The date went better than either of the siblings could have expected. They went to a local Italian restaurant, and Cindy taught her b*****r about little things, like holding the door for a girl or pulling her chair out for her. Once they were seated, they talked about how Cindy had been doing at medical school, what Ryan wanted to do after graduation, and about movies they had watched and books they'd read.

All throughout, the two acted far more like a boyfriend and girlfriend than like a b*****r and s****r, exchanging a quiet, intimate smile or lightly flirting. Cindy caught Ryan glancing at her breasts several times, and at one point even propped her elbows on the table and leaned forward on her crossed arms, pushing her breasts up and giving her b*****r a better view. Finally, they paid for their food and drove back to the house, and Cindy was pleased to see that Ryan remembered to open the passenger side door for her.

"So," Cindy said as they reached the front door, "would you like to come in?" Ryan laughed, and the two went into the house and sat on the couch.

"Thank you, Cindy," Ryan said, smiling warmly at his s****r. "This has been wonderful, and I really appreciated the little lessons you gave me." He shifted somewhat, and it was hard for Cindy not to notice his erection. Now she reached over and cupped his cheek, turning his face back to hers.

"You know," she said, her voice low and breathy, "the lesson doesn't have to end here." She ran her thumb across Ryan's lips, and he parted them, taking her thumb into his mouth and sucking gently on it. When she removed it and pulled on him, drawing his face closer to hers, she saw tears forming in his eyes, and he drew a shaky breath.

"Cindy, I..." Ryan trailed off, backing away from her as fully formed tears started sliding down his cheeks. Immediately Cindy let go of his face and grabbed his hands.

"I'm so sorry, Ryan," she said, getting off the couch to sit in front of him. "I didn't mean to f***e you." She would have continued, but Ryan shook his head.

"No, that's the problem," he said, pain clearly evident in his voice. "I want this too; I want you. I guess I've been having these thoughts since the beach on Friday, but I can't do this. It's wrong." Cindy got up onto her knees and slipped her arms around her little b*****r's neck.

"Hey," she said, looking into his eyes. "I felt the same way you did at the beach, and I had the same reaction to it, but then I thought about, I mean really thought about it. I know it's dangerous if we have k**s, doubling up on alleles and all that, but I'm on the pill, so that's not a problem. I also know that it's i*****l, but nobody has to know about us, okay?" Ryan's crying lessened, but he was still clearly upset.

"But what about damage? You know, like mental damage?" Cindy smiled reassuringly at her b*****r.

"It's okay," she said. "If we were five or ten years younger, then yeah, it would probably be abusive and could do psychological damage. But you're not a little boy anymore, and I'm not a little girl. You won't be abusing me." She took one of Ryan's hands and pressed it to her chest, right above her heart. "And I promise you, baby b*****r, I will never make you do anything you don't want to. If you ever feel f***ed, just tell me and we'll stop, okay?" She released Ryan's hand and gently stroked his cheek, and he nodded, smiling.

"Thank you, Cindy," he said. "I love you."

"I love you too," Cindy said, climbing up and straddling Ryan's lap. She could still see tears shining on his face, and she leaned forward and gently ran the tip of her tongue up his cheeks, tasting the salty liquid as she swept it from his skin. Ryan gasped, shuddering at the incredibly erotic sensation of his big s****r licking away his tears. Finally, Cindy slid her face over and the siblings' mouths met in a hot, sucking kiss, lips sliding against each other. Ryan's arms went around his s****r and pulled her flush against him, pressing her soft warmth against his body as he opened his mouth and Cindy rolled her tongue against his.

At last, they broke for air, gasping, and Cindy gave her little b*****r an impressed smile.

"Looks like I don't need to teach you about making out," she said. "You're already great at it!" Ryan beamed with pride and moved to kiss her again, but Cindy ducked her head and began kissing the soft flesh of his neck while her hands went to the top button of his shirt. Slowly, she spread the shirt open, licking and sucking at his skin as she went.

"When we were at the beach, I saw the water running off you, and I wondered what you'd taste like," she said, pausing to suck at Ryan's nipples, loving the rubbery, faintly pebbled texture against her tongue. "Now I get to find out." Slowly, Cindy made her way down her b*****r's abdomen, before finally reaching his belt. "Let's see what you have for me, baby b*****r." As her hands worked on his buckle and zipper, Ryan suddenly grew nervous.

"Cindy...I..." he started, and then closed his mouth.

"Do you want to stop?" Cindy asked. "Remember, we can if you want." Ryan shook his head.

"No, I want to keep going. It's just I'm afraid I might not be...enough for you." Cindy almost asked what he meant, but then it hit her, and her heart ached for her b*****r. Wanting to reassure him, she quickly hooked her fingers into his pants and boxers and pulled them both off, freeing his erection. She smiled.

"You were worried you wouldn't be big enough," she said, grasping his shaft with her right hand and slowly pumping it. Ryan nodded.

"I'm a virgin, but I've read stories, and the guys are always eight or nine inches, so I figured you'd be disappointed." Cindy happily shook her head.

"I haven't had a ton of boyfriends, but I've read enough in the medical books to know six inches is normal. You're not a porn star; you're human. Besides," she said, "six inches is a lot easier to take in my mouth." With a salacious smile, she opened her mouth and ran her tongue slowly up the underside of her b*****r's cock, licking over the glans and exploring the hole at his tip. Ryan gasped and shuddered with pleasure.

"s*s, that feels so good," he said, looking down at Cindy with something very close to awe. With a final flick at the tip, Cindy withdrew her tongue.

"It's about to get a whole lot better." Without any further talk, she bent down and wrapped her lips around his length. Ryan threw his head back, hands squeezing the sofa pillows as his s****r slid her hot mouth up and down on him. Cindy relaxed as she got to the base, and then sucked hard as she drew back toward the tip, her cheeks contracting as she pulled on his flesh. After about a minute, she heard Ryan panting.

"s*s," he got out between breaths. "I'm gonna...I think I'm gonna—"

"Let it go," Cindy replied, pulling her lips off him and blowing gently on the tip. "I'll take it all." She immediately took him back into her mouth, as deep as he would go, and sucked as hard as she could. As her little b*****r twisted back and forth on the sofa, Cindy caressed his shaft, feeling his frantic pulse against her tongue. Finally, Ryan cried out and burst in her mouth, painting the back of her throat with jets of hot semen. Cindy kept sucking until she was sure he was done, and then pulled back, releasing his cock with a soft pop, and tilting her head up so he could see her throat as she swallowed.

"Wow," Ryan breathed. "That was amazing."

"Mmm," Cindy hummed, slithering up his body for another wet kiss, "I'll bet it was, but here's another lesson: always make sure the woman has her pleasure too. Make sure it's not just about you. Now, come on, Ryan." Standing up, she took his hands and pulled him toward her bedroom. "Make your big s****r happy."

In her room, Cindy turned on only the bedside lamp, casting everything in a soft, warm orange glow. At her direction, Ryan lay back on the bed and watched as Cindy slid first one, and then the other of her dress straps off her shoulders, and his eyes followed the garment as it slid down to pool at her feet.

Underneath the dress, Cindy was clad in lacy red panties and a matching bra, the cups high enough to cover her nipples and areolae, but just barely. She had picked the underwear out hoping that Ryan would like them, and judging by the look on his face, he fully appreciated it.

With teasing slowness, Cindy reached behind her back and unhooked the bra, letting it fall away to expose her ample breasts and pert, pink nipples. Never taking her eyes off her b*****r's, she slid the panties down her legs and tossed them away, revealing her silky thighs and shaved pussy, lips already glistening with her arousal.

"Cindy," Ryan said, again with a look very close to awe, "you're so beautiful." Cindy's heart swelled at her little b*****r's compliment, and she had to fight back a lump in her throat.

"Thank you so much, Ryan," she said, before walking slowly to the bed and crawling up to lie next to him. Grasping his shoulder, she gently pulled him on top of her. Later, there would be time for her to be on top, but this first time she wanted Ryan to be able to explore, to touch and taste to his heart's content. "Now," she said, "make love to me."

Ryan stroked her face, before covering her mouth with his for another deep kiss, their tongues dancing together. Pulling away from her mouth, next he did what she had done to him, kissing and licking his way down the soft flesh of her throat. Cindy ran her fingers through Ryan's hair, gently guiding his head down to her breasts. When he reached them, Ryan pulled back for a moment, reaching up to cup the smooth mounds, squeezing gently before rolling them back and forth, thumbs rubbing her hard nipples. Cindy hummed with pleasure, but wrapped a hand around the back of Ryan's head, pulling him down.

"Suck them," she whispered, before inhaling sharply as her little b*****r closed his mouth around her right breast, sucking at the soft flesh with unbridled enthusiasm. Releasing some of her breast, he focused his suction on the area around her nipple, dragging his tongue across the hard nub, and even biting down on it ever so softly. Cindy reluctantly guided Ryan away from that breast, only to sigh with joy as he began sucking and licking at the other one. His left hand was under her back, pulling her up to f***e as much of her as possible into his mouth, as his right slid down her back to cup and squeeze her ass. Soon, far too soon for Cindy's liking, Ryan pulled his mouth off of her, leaving her breasts glistening with his saliva.

"Oh, baby b*****r," Cindy moaned, "you're so good to me." She began to gently push him down along her stomach, tensing in pleasant surprise as his tongue flicked into her navel. "Now I need you to take that wonderful mouth of yours somewhere else." As she spread her thighs for him, Ryan hesitated, and Cindy realized he needed a little more guidance.

"See that little bud up there at the top?" she asked. "That's my clitoris. It's very sensitive, so pay special attention to it. Other than that, you can do whatever you want. Use your fingers, your tongue, anything." Ryan needed no more encouragement, and he leaned in and covered her vaginal lips with his mouth, sucking on her labia and thrusting his tongue as deep into her as it would go. Remembering his s****r's words, he took her clit between his lips and sucked on it, licking and tugging at it. Up above him, Cindy's eyes were squeezed shut, her brow furrowed as she focused all her attention on the amazing sensations her b*****r's lips and tongue were giving her.

"Keep it up," she panted. "I'm going to come!" Ryan redoubled his efforts, sucking hard at her clitoris and thrusting one, then two of his fingers inside of her.

"Oh, God, Ryan! Yes! Yes...YES!" Ryan inadvertently brushed his fingers over a sensitive spot inside her, and Cindy's orgasm crashed over her like an ocean swell, causing her to clamp her thighs around his head as stars burst behind her eyes. As her vision came back into focus, she saw Ryan climb back up beside her, and she pulled him in for another kiss. "You did great, baby b*****r." Ryan smiled, blushing.

"I have a good teacher," he said. "I don't know if I should say this, but I'm really glad I'm learning this with you." Cindy felt her heart swell with love again, and she kissed her b*****r one more time, a soft, warm press of lips on lips. For a moment, the siblings just stared into each other's eyes, until Cindy became aware of Ryan's erection pressing hot and heavy against her thigh.

"I think it's time for the best part," she said, pulling him up on top of her again. Taking him into the cradle of her thighs, Cindy reached down and took hold of his penis, guiding it to her wet entrance. "Now," she said, returning her gaze to Ryan's eyes, "just push gently." Doing as his s****r instructed, Ryan thrust forward, and began to push into her.

In spite of the lubrication provided by her first orgasm, Cindy was still tight, and both siblings gasped as he filled her, stretching her inner walls and making her shiver. She didn't tell him to wait for her to adjust to him, but it seemed he knew, or perhaps was struggling not to come immediately. Either way, it was exactly what she needed. After a moment, she wrapped her arms around his neck and pulled his forehead down to rest against hers. "Okay," she said. "You can start now." Nodding, Ryan started slow, but immediately accelerated, pounding into her f***efully. At this rate it wasn't going to last, so Cindy gripped her little b*****r's hips, slowing him down.

"What's wrong?" Ryan asked.

"Why are you going so fast?" Cindy responded. "You don't need to."

"Well, I remembered what you said. I wanted to make sure that you...you know, before I did." Cindy kissed her b*****r gently before speaking again.

"Thank you," she said, "but don't try to f***e it. Go slow and just let it happen."

"Okay," Ryan said, nodding. He started to thrust again, but this time gently, moving in and out of his s****r with slow, measured strokes. Occasionally he leaned his face down to Cindy's for another kiss, but for the most part the two just watched each other, wrapped in their own universe, where nothing existed except the warmth they were giving each other. Eventually, however, the heat between them grew, and they did speed up, the room filling with the sound of flesh striking flesh, as well as panting and cries of pleasure as the siblings fucked with reckless abandon, mouths open as they gasped for breath, the headboard slamming against the wall.

"I'm close, Cindy," Ryan said, his breathing ragged. "I'm so close."

"I am too! Fuck me, baby b*****r, fuck your big s****r!" Cindy gripped Ryan tightly, pounding their hips together. "Oh, God, so close!" she whined.

"What...what can I do?" Ryan asked. Cindy bit her lip and moaned.

"My breasts," she said. "Suck on my breasts again!" Without another word, Ryan bent down and wrapped his mouth around her right breast again, sucking hard and scr****g his teeth over the supple flesh, and that was it. Cindy screamed, and the room around her seemed to white out as she exploded in the most intense, incredible orgasm of her entire life. Her inner muscles constricted around Ryan's length, and she could feel him lose himself, spurting jet after jet of hot seed inside of her.


Later, much later, Cindy opened her eyes to find Ryan lying next to her, watching her through half-closed eyes.

"Hey," she said tiredly. It was an inane thing to say, and she chuckled at her own stupidity, but Ryan grinned too.

"Hey," he replied. "So, was I good?" Cindy reached over and ran her fingers across his lips.

"You were amazing," she responded, sliding over so that they were mere inches apart. "You're a wonderful lover, baby b*****r."

"Thank you. I love you, Cindy."

"I love you too, Ryan," Cindy replied, pulling him into her arms.

"So, do you think we can ever do another lesson like that again?" Cindy grinned at her b*****r's question, and leaned in to run her tongue across his lips.

"We have four more days until Mom and Dad get back, and I think I can teach you a lot in that time. Now let's get some sl**p." Cindy reached over and switched off the lamp, and Ryan laid his head against her breasts and shut his eyes. Soon, Cindy drifted off too, thinking of what she would teach her b*****r in the morning.

The End.
