Chapter Text
“You are man now Onii, strong and capable like your father.” It was what my father had told me shortly after my sixteenth birthday. “That’s why I feel good about leaving you to protect and take care of your sister.”
He was leaving us, something he had been itching to do for years. My mother had died giving birth to my sister twelve years ago. It was a hard time for all of us, but my father stuck around to take care of me and my sister. He was an adventurer and always longed to get back out into the world. It was plain to see that he resented being stuck in a small rural town like Mecau, but he did a good enough job of looking after us.
Clearly he was waiting for my sixteenth birthday, when he determined I was a man and capable of taking care of myself and my little sister. And so he ventured out, leaving me with a log house on the outskirts of town, a simple iron sword, a small sum of gold and a sickly sister to care for. My sister cried at his sudden departure, but I quickly accepted it, along with my responsibilities as man of the house. I would do what I had always done and take good care of my little sister.
I dreamt of becoming an adventurer like him, and I joined up with the small-time local adventurer guild as soon as I had turned sixteen and was old enough. It was run by an elven woman named Yukari. I was also joined by my childhood friend Kana, and the caring, softly-spoken healer, Yui.
“Wake up, Onii-chan!” I stirred in my bed as my sister pulled off the blankets. I rolled over and saw my sister look down and then quickly look away, her cute suddenly looking flustered and blushing. I had morning wood, my stiff cock poking up and tenting my boxers. I quickly sat up and covered my erection, feeling embarrassed. “You need to get ready to go to work,” she said, shyly looking away.
“Yeah, I’ll be out in a minute.”
She nodded and left our shared bedroom. I sighed as I got up, my erection strained against my boxers. It would go away soon enough. I think my sister was just as embarrassed as I was at seeing it. I went into the bathroom and splashed water on my face, my dick had softened enough for me to go into the toilet and take a piss. As I came out from washing my hands, my sister had a bowl of warm porridge waiting for me.
My imouto, Aiko was a little cutie. She was quite petite and slender, with a pretty face. Her hair fell down just past her shoulders, and she wore it in tails with small red ribbons. Her hair was snow white, which was quite unusual, but I attributed it to her reoccurring illness. My own short hair was a sandy blonde color. Her skin was smooth and fair, not like my own tanned complexion from spending time outdoors. And she had large green eyes which made her look quite adorable.
I sat and ate breakfast with Aiko before we cleaned up and left the house together. My little sister was dressed in her school clothes, a grey blazer and navy blue skirt. “Have a good day, Onii-chan,” she said as she left to go to school. I walked down the road in the opposite direction toward our modest guild hall. The skies were a little cloudy and there was a cool breeze as I walked down the dirt road.
Mecau was just a small town, surrounded by numerous farms. There were forests and a lake nearby, it was a naturally beautiful spot, but not a lot happened there. Some would say there wasn’t even a need for an adventurers guild. We would occasionally kill wild boars that wondered into farms, for a small amount of gold. The rest of our time we divided between training and doing various jobs around the community.
I saw Kana and Yui walking together as I got to the guild hall, and we greeted each other. Kana was my long-time friend and a bit of a tomboy. She was also training with the sword, like me and dreamed of becoming a famous adventurer. We had a friendly rivalry going, and often it felt like she was just another guy. I didn’t fail to notice she had become quite attractive, though. Her chest had been filling out nicely these last few years.
She was had black straight hair which fell around her neck, framing an attractive freckled face with dark brown eyes. She wore a brown skirt with long form-fitting leggings. A black belt encircled her waist, which held her sheathed sword. She wore a tight white long-sleeved shirt. Kana was close to the same height as me, falling just a little shorter. She had an athletic build, though with some noticeable feminine curves.
Yui was also a pretty girl. She was also around my age, noticeably shorter than me and Kana. She had light blonde hair in a bob cut and a cute round face. She wore a flowing apron-style dress with and undershirt with long white sleeves. She also wore a white nurse cap with blue tussles. She had trained in the Yunaleska temple and could perform healing magic, though she was still just a novice.
We all walked into the small guild hall together. Yukari was behind the long oak counter, waiting for us. She was a tall slender elf with long straight blonde hair and long pointed ears. I never had the courage to ask how old she was, but Kana told me she would be well over one hundred years old. No wonder she always looked at us like we were children.
“Good morning guild members,” She said in greeting. “There isn’t much going at the moment, so I’ll leave it to you to decide if you want to train or do community service today.”
Kana let out a sigh, but it was fairly typical that there wasn’t much going on in this small town. It kinda made me worry that the guild hall could continue to operate. “I think we should go for a run, build up our endurance,” she suggested.
“Yeah, let’s spend the morning doing that,” I agreed. “But in the afternoon we could do odd jobs around the town.” I still needed to make money to support me and my sister, and we could make a few coin working for various folk around town and the farms.
And so the day passed, we trained in the morning and worked in the afternoon at Old Miamoto’s farm. “You kids ought to quit playing adventurer and get proper jobs,” said the farmer. “We have a proper guild not too far away in Taun. That elf is just filling your heads with daydreams.”
“Yeah, but we’ll be the ones you come running to if a wild boar comes onto your property, you old Toad.” retorted Kana.
The clouds in the sky grew darker as we worked. As we walked back to the guild hall, finished for the day, drops of rain started to fall. I was drenched with rain as I walked back home. When I got back to my house, I went straight to the bathroom to change out of my wet clothes.
“AGH, ONII-CHAN!” I was surprised to see my sister in the bathroom…stark naked. I looked at her for only a second as she covered herself up as best she could, looking mortified. “Get out!”
“Sorry, sorry,” I said, quickly stepping back and closing the door. I let out a long breath as I my wet clothes dripped onto the floor. The image of my naked little sister was burned into my mind. Her wet white hair clinging to her bare shoulders. All of that smooth fair skin, her chest was mostly flat but there was the subtle hint of breasts beginning to form around her supple pink nipples. The small dark indent of her navel on her flat belly and the bald mound between her thighs, the small crack of my sister’s pussy.
Aiko soon stepped out, now dressed in her polka-dotted button-up pajama top and short pants. She looked at me annoyed, “Don’t just barge into the bathroom like that, Onii-chan. That was embarrassing.”
“I said I was sorry. I didn’t see anything.” She huffed as I stepped into the bathroom and got out of my wet clothes and dried off. Aiko made us a nice soup for dinner, as she liked to do when it was raining. We could hear the constant patter on the thatched roof as we enjoyed the meal together. She was really quite a good cook.
“Can you read me a story?” she asked after I washed up the dishes.
“Your old enough to read a book by yourself.”
“Yeah, of course. But I like it when you read to me. Please, Onii-chan?” She sounded so sweet when she asked like that, I couldn’t refuse her. She used to like children’s stories, but now she was into more grown-up adventure tales. She picked a book we had already read through a few times, and sat down as I read to her.
Eventually she stretched and let out a yawn. “It’s getting late. Are you going to bed, Onii-chan?”
“Yeah, you get yourself tucked in, I’ll come to bed soon,” I said as I put the book away. As she went into our bedroom, I went into the toilet. The rain continued to patter down on the roof. Sitting on the toilet seat, I rubbed my member and it quickly grew big and hard. I was feeling horny and wanted some relief before bedtime. I often though about Kana or Yui as I fapped, I had dirty fantasies about both of them. Sometimes I imagined getting it on with Yukara, too. The older elf could teach me a thing or two.
And then I saw my naked sister as I stroked my rigid cock. What flustered faces would she make as I ran my hands over her petite body? How would it feel to push my cock up into her tight little cunny. The thought excited me as I gripped my meaty pole and pumped it hard. Soon I let out a soft groan as I my cock throbbed in my hand and I felt the pleasurable release as it spurt a load of cum into a handful of tissue paper.
I felt a pang of shame as I cleaned up. What kind of pervert jerks off thinking about his kid sister? It felt good, though. When I went back into out bedroom, Aiko was laying in her bed with her eyes closed, her chest steadily rising and falling. I leant down and kissed her forehead, “Goodnight, sis.”
“Goodnight,” she said softly, not yet asleep.
I snuffed out the light and got into my own bed at the other side of the small room. I soon drifted off to sleep, listening to the steady drizzle of the rain.
The next day was much like the last. The rain had cleared up, and it was clear and sunny. We did combat training in the morning and continued our farm work in the afternoon. I arrived home feeling pretty tired and found my little sister in her pajamas lying in bed.
“Not feeing well again, sis?”
“No,” she said, sniffling. It was nothing new, these bouts of sickness came and went at regular intervals. She would feel very weak and run down, often feverish. It baffled the doctors, who said she just needed bedrest and care when it came. I nursed her through the night, and thankfully her fever had receded the next day.
Nothing exciting happened for the rest of the week, I trained and worked during the day with my guildmates and spent cozy nights with my sister. We both got weekends off and liked to do things together.
“Oh please, can we go into the city tomorrow, Onii-chan?” my sister asked sweetly. She enjoyed our trips into the nearby city. I had made some spare coin during the week, so I agreed. “Oh, thank you,” she said happily, giving me a tight hug.
So, on Saturday morning we took the carriage bound for the city of Bear Taun, usually just referred to as Taun. It took a little over an hour to travel there and my sister was smiling all the way. She was wearing her nice sky-blue billowing dress and a bonnet. Taun was a walled city, much larger and busier than our sleepy little town. The cobblestone main street was lined with numerous shops, bars and restaurants.
Aiko looked around whimsically at all the bustling activity around us. The first place she wanted to visit was predictably the bookstore. It was a large stone building with rows of shelves lined with many different types of books.
“Go find a new book you’d like and I’ll buy it for you,” I told her.
“Yay,” she said happily and went straight over to the adventure section. I perused the section of books for a while. Eventually we purchased a couple of new books. Aiko chose one called, “The Warlock of Firetop Mountain,” and I found one on battle tactics.
We left the store and I bought us some drinks from the juice stand to enjoy as we walked around. In one of the back streets, I noticed a strange store that I hadn’t seen before. The simple wooden sign out the front read “Estrus Pleasures.” I stood out the front, trying to peer into the dusty window, wondering what it was they sold.
The proprietor then appeared at the doorway. He was slim man in his thirties with straight black shoulder-length hair and a neatly trimmed goatee. “Curious, young fellow? Why don’t you come in and have a look around?”
I looked at him and nodded slowly, “Yeah, allright.”
“What is this place?” asked Aiko.
The man held up his hand to her, “Oh, I’m sorry little girl, this is a store for adults only.”
Now I was quite curious. “Why don’t you go watch the street performers?” I told her. I then handed her a couple of coins, “Here’s some coins you can give them. I’ll meet up with you soon.”
She nodded and took the coins. “Okay then.”
I watched her walk down the street and then followed the man inside. There were no other customers inside. The store was dimly illuminated with strange purple lights. I could see a variety of items on display, there were different sets of fur-lined hand cuffs hanging on the wall, blindfolds, strange masks, lacy sheer women’s clothing, shelves with books and containers on the far wall with what looked like tea leaves. I saw a case with multiple phallic shaped objects of different shapes and sizes.
“So this is a sex store?”
“You could call it that,” said the shopkeeper as he stepped behind the counter. “Was that little cutie your sister?”
“Yeah…” I said, looking at some strange bulbous bullet shape objects on the shelf.
“Do you enjoy all the benefits of being a big brother?”
I looked at him, “What do you mean?”
“I mean do you have fun with her?”
I nodded slowly, but then took his meaning. “Like…sex? No! She’s my kid sister.”
“Hmm, but little sisters are the best,” he said with a smile. “I thoroughly enjoyed mine when I was your age.”
He was sounding really creepy, I should have walked out, but I chose to stay. “I love my sister, I wouldn’t abuse her.”
“Who’s talking about abuse?” said the shopkeeper. “If you groom her right, she will want you, and she will enjoy the sex.” I stood silent as he walked over to the bookshelf. “I have a book right here about a brother and sister who become passionate lovers.”
I looked at it curiously as he laid it onto the counter. The title read, “Sibling Secrets.”
“It is erotica fiction. I think you would enjoy the explicit detail.”
“How much is it?” I asked.
“Forty gp.”
“That’s a lot for a book.”
“Rare edition,” he replied. “If you don’t enjoy it, you can return it for an exchange or refund.
I sighed as I got out my coin purse, “Okay, I’ll take it.”
“Good choice,” he said as he began to wrap the book in brown paper. “And just for you, I will throw in a little bonus.” He pulled a tiny packet out from a drawer. “A single dose of Sleep Tea. Give this to your sister and she will fall into a very heavy sleep. Perfect for some late night exploration, if you know what I mean.”
I was Taken aback, a little shocked and excited at what he was suggesting. “It’s not harmful for her, is it?”
“No, quite the opposite. She will awaken fully rested and feeling great. I take it myself sometimes.”
I paid him the gold and took my purchases, putting them into my bag. “Enjoy,” said the shopkeeper as I walked out. “Come again some time.”
I walked down the street feeling a little bemused by the exchange. What a strange man, and a strange store. I had never talked to another guy like that before. I met up with my sister in the square, she was smiling as she watched a clown juggle several colorful batons. Another performer played an upbeat melody on his hand accordion nearby.
“Hey Onii-chan,” she grinned as she saw me. “What was up with that place? Why was it for adults only? Where there dirty pictures or something?”
“It was nothing interesting. Pretty boring. That guy was just being weird.”
“Yeah, he was pretty weird,” she agreed.
“Do you want to go and get something to eat, sis?”
“Yeah, pizza rolls!” she beamed happily.

We arrived back in Macau in the afternoon. My sister was in a good mood for the rest of the day. She really enjoyed going out to the city. She gave me a tight hug when we got home. “Thank you, Onii-chan, you’re the best.” I hugged back, enjoying her body pressed into me. Was it true what the strange man had said? She would want to have sex with me and enjoy it?
Aiko prepared a nice dinner to show her appreciation. I was looking forward to reading my new book, the dirty one, not the one on battle tactics. After washing up, my sister stood before me, smiling sweetly. “Can you read me my new book now, Onii-chan?”
“Can’t you read it yourself. How about we each read our own books?”
“But it’s a new book, and I want to enjoy it with you. Pleeease.”
I sighed, I was a sucker for that cute pleading face. “Allright.” My naughty book could wait.
She made herself comfortable on the bed and I read The Warlock of Firetop Mountain to her. It was a pretty good book. Aiko snuggled up to me during some of the scary parts, and I could smell the sweet floral scent of her hair as she rested her head on my chest.
It got late, and my little sister was yawning, which was contagious. Eventually I put the book away and we went to bed. My cock grew stiff and I jerked off under the covers, giving myself some relief before I drifted off to sleep.
-
It was a hot one the next day. We decided to go down to the lake for a swim. Mecau Lake was just a twenty minute walk down the dirt road. My sister hummed happily as she walked beside me. She wore her dark blue one-piece swimsuit. I liked the way it tightly clung to her petite body, hugging the smooth curves of her mound. It brought back the image of her nude body that I got a glimpse of when I walked in on her.
“Why are you looking at me like that?” she asked as she stood by the wide placid lake.
“You just look very pretty in you swimming costume,” I said with a smile.
“Aw…thanks,” she said with a blush. She then turned to slash her toes in the water. “Come on in with me, Onii-chan.”
I stripped down to my board shorts and walked in. Aiko chuckled as she plopped herself down into the clear water. I came over and sat down beside her, the water coming just below my chest. My sister stroked her arms through the water and looked at my bare chest. “You’re starting to build some muscle, Onii-chan.” She leaned over and brushed her wet hand down my bicep.
“Well, I’ve been training hard.”
She chuckled softly, “Heh…you’ll become stronger than dad.” I grinned and then splashed some water in her face. “Ooof, Hey!” she cried and splashed me back.
We played and swam in the cool water for a while. Then I told her to come out into the shade. She had fair skin, and I didn’t want the sun to burn her. I sat with her, chatting for a bit and then we heard some rustling nearby.
“Froggy!” exclaimed Aiko. She bent down to get a closer look at the large green frog and I was treated to a view of her firm little butt and her fabric-covered mound sticking out. I licked my lips as dirty thoughts filled my mind. I wanted to stick my face into her crotch. The frog promptly hopped away and she looked back at me with bemusement.
We made our way back home for lunch and had a lazy Sunday afternoon to ourselves. I settled down and started reading my erotica book. My sister was content to continue reading the adventure book where we left off.
The main characters were a brother and his sister, twins around my age. They lived in a wealthy estate with their parents. It was clear they had a close, loving relationship, and I could see a lot of familiarity with the way me and my sister interacted. There was a lot of sexual tension building there, too. In one scene, the brother crept over to his sister’s bed late at night and started to molest her in her sleep. She woke up feeling very aroused and wanted him. The book then had a very explicit, detailed description of the two them passionately fucking while their parents slept in the next room. It was hot, and my cock got rock hard as I read the erotic scene.
Later that night, after we had eaten dinner, my sister had taken a bath and changed into her cute long button-up nightshirt and short cotton pants. “Should I brew up some tea?” I asked her.
“Oh yeah, sounds good.”
She sat on our comfy lounge chair as I heated the water. I got out the small bag of sleep tea that the shopkeeper had given me and brewed it up for my sister. I also made a cup of black tea for myself and we sat at the table to drink it.
“Mmm, this is a bit different,” said my sister as she sipped the tea.
“Do you like it? I got it from town.”
“Yeah, it’s not bad.”
We chatted lightly as we finished our cups of tea. Not long after, I could see my sister’s eyelids getting heavy and she let out a yawn. The Sleep Tea was taking effect. “Hmm, I might go to bed a bit early tonight,” she said with another soft yawn.
“Okay, goodnight, sis,” I said, giving her a kiss on the forehead.
I took my erotic book and sat down, reading through it as my sister settled into bed. My arousal grew as I read through the sex scene again. I was feeling pretty excited, my body warming with anticipation. Soon I put the book down and went into the bedroom. “Aiko, are you awake?” I asked. It was only around twenty minutes since she went to bed. She didn’t respond. I could see her lying on her back on the bed with her eyes closed, her chest steadily rising and falling. She looked very peaceful.
I went and stood over her, studying her cute placid face. I cupped her face with my hand, rubbing my thumb over the smooth skin of her cheek. The tea certainly seemed to do its job. Just how deeply was she sleeping?
My heart thudded in anticipation as I began to undo the buttons her nightshirt, one by one. I then pulled the light material apart, revealing her bare chest. She was flat, her breasts barely beginning to develop, but the sight of her puffy pink nipples was enticing. I lightly rubbed my hands along her body, watching her face as she continued to sleep soundly. My hands cupped her chest and thumbs rolled around her nipples, feeling the gentle bumps of her flesh. I let out a hot breath, my cock was straining in my pants as it stiffened. I gave a light squeeze, feeling up her warm body.
My hands then slid down along her smooth skin, over her trim belly. Fingers hooked into the waistband of her cotton shorts and I slowly pulled them down. The shorts slid down, revealing her white panties. I continued to carefully pull them down along her slender thighs and slipped them off over her delicate feet.
I looked up at the white panties hugging her crotch. My fingers slid along the material and gently pressed into her mound, feeling the soft flesh beneath. I was touching my little sister’s pussy through her panties. I looked over to see her peaceful face, her lips parted slightly as she took in deep steady breaths. I pulled down my own pants to free my straining cock.
My fingers rolled around the crotch of the panties and I experimentally started to push my fingers against it harder, enjoying to feeling of the soft warm flesh pushing back. My middle finger rubbed up the center, tracing the indent of her little slit. With a few harder strokes, I could feel the dampness start to seep into the material.
I then got hold the waistband of the panties and slowly and steadily began to pull them down. This was it, my heart pulsed with excitement, my dick throbbed with arousal. The white panties peeled back to reveal her bare smooth mound and then her thin cleft that split it. I licked my lips as I pulled her panties down further around her creamy thighs.
My hand slid up over her crotch, gliding over the smooth skin. I delicately spread her mound apart and leered at the thin pink lips. What a pretty cunny my sister had. My finger ran along the slit, feeling its soft warmth. I pressed harder against it, and could feel the dampness. I looked up again at her placid face, she was still in deep sleep, unaware that her big brother was touching her pussy.
My excitement grew. I knew I shouldn’t be doing this. I had no excuse if she woke and caught me. I knew it wouldn’t be like the book, where she would wake up and want me to fuck her. It would probably damage the trust she had in me. But I reveled in the thrill of the forbidden. My fingers continued to rub lightly around her soft folds. She showed no signs of stirring, and would likely keep sleeping as long as I didn’t get too forceful with my touching.
I rubbed my finger up, splitting her pink lips as they were dampened with her arousal. I then licked my finger, tasting her. I couldn’t hold back, I moved my face down to the crotch and took in her distinct scent. My tongue poked out and sunk into her cleft. It rubbed over the warm soft folds. I could taste her, and I could feel the yielding warm flesh push back against my tongue. My rigid cock throbbed with desire.
A gave several long wet licks along her slit and then I heard Aiko let out a soft sigh. I jerked my head up, relieved to see that she was still fast asleep. I moved my head back down to her crotch and closed my lips, gently sucking on her soft folds. My tongue slid up along the slippery skin and found the tiny nub of her clit, rolling around it.
My cock felt like it could burst. I lifted myself up and got a tight grip on the shaft, giving myself a few pleasurable strokes. I shuffled up on the bed and then brought my cock down to meet her little wet pussy. The fat tip slid up against her wet pink lips. As much as I wanted to push it inside her, I held myself back. Penetrating her would wake her with a painful shock, and I was not going to abuse her.
I slid my tip against her one more time and then I gripped the shaft tightly and began to fap. I looked down at the pretty placid face of my little sister, and her exposed petite body as I gave myself hard pumping strokes. Soft groans escaped my lips as I felt the pleasure rise in my rigid manhood. Then I couldn’t hold it back any longer, I growled as my cock throbbed in my hand and then came the pleasurable release of my climax. Pearly cum spurt from the tip and spattered over the smooth skin of my sister’s crotch and belly.
I breathed hard as another wad shot out onto my sleeping sister. Aiko still slept peacefully. I let out a satisfied sigh as I shuffled off of the bed. I reached for the tissues on the nightstand and wiped myself down, before carefully wiping the creamy cum off of my little sister’s naked body. I proceeded to pull her panties and shorts back into place. I buttoned her nightshirt back up as she continued to sleep soundly. She would never even know what happened, and I was thankful for the Sleep Tea.
