I hadn’t had a real chance to talk with Jenny, my fourteen-year-old sister, since we made love during their lunch break at school today. We had shared our passion, committing the most wonderful incest I could imagine. We took each other’s virginities and discovered new aspects of each other. I had no idea my little sister was so hot. So sexy. So wanton.

She had been an eager and active participant, falling to her knees, sucking my cock, begging me to pop her cherry, to cum in and breed her. It had been so wild hearing my uptight, little sister say those words. I never thought she was interested in sex. Not really. She dressed so conservatively, baggy clothing, long skirts, high necklines. Not like the other fourteen-year-olds at our high school.

Or the fifteen-year-olds in my grade.

When she burst in on my secret spot on the school grounds where I vaped, a small clearing amid rhododendron bushes behind the school’s gym, I had thought she would tattle to our mother. Mom was a doctor, and she hated smoking. Jenny was always tattling on me, following me around, being annoying.

Now ... she could follow me around all she wanted.

What I did not expect to happen after she caught me was for Clint and his little sister, Alicia, to have sex where we could watch. Clint was a legend at our high school. Last year, when I was a freshman, he was the junior who had knocked up Pam Hiragawa and his cousin Melody Samuels. He strutted school with both girls on his arms, his own private harem. Rumors persisted he even fucked his other cousin, Lee; his two sisters, Zoey and Alicia; and his aunt, Ms. Samuels, who taught me History this semester.

It had been so hot hearing Clint fuck his little sister. He took her hard. She begged him to cum in her, to breed her. Jenny and I had listened, growing hotter and hotter. There was such envy in Jenny’s eyes as Clint devoured Alicia’s pussy.

And then we were masturbating. I was stroking my dick, my sister fingering her twat. We grew hotter and hotter, and before I knew it, I was devouring Jenny’s pussy. I made her cum. I fucked her. Came in her.

And that, I think, was why she was so nervous when the school bus dropped us off. She was silent as we walked home. Normally, I wouldn’t have even said anything to her, letting her walk ahead while I texted my friends.

“You okay?” I asked her as she walked, so tense, up to the door of our house.

“I’m fine,” she said, her voice strained.

Jenny was a cute girl, her light-brown hair held back from her face by a pink headband, her cheeks delicate, her lips pink and kissable. Beneath her dress and tights, she had a sexy body with round breasts and pink nipples and sleek thighs. She definitely could dress better.

“Is it about what we did?” I asked as she pulled out her keys from her purse. Mom was at her practice and Dad was long gone. “It takes more than once to get pregnant.”

Jenny shook her head. “I’m in the middle of my cycle.” She jammed the key into her lock. “It’s the best time for me to get pregnant. And it can take only once.” She shivered. “The precum alone leaking from your cock has enough sperm in it to impregnate me.”

“Really?” I asked.

“Didn’t you pay attention to Mom’s lectures?” Jenny shouldered open our front door. “She was quite clear with me.”

Our mother was a gynecologist and an obstetrician. If anyone would know, it was her. I swallowed, my stomach tensing. “So ... is it for sure that I... ?”

“Knocked me up?” Her voice grew brittle. “No. There’s no guarantee your sperm will find my egg. There’s a lot of factors from incompatible blood types to acidity levels in my vagina to your sperm’s mobility. It’s why couples can try for months and months and not conceive. But...”

She walked to the couch, dropped her purse and bookbag, and slumped down onto it, her face pale. I closed the front door and followed her. I sat down beside her, closer than I would have. Things were different between us. What happened today was special. She was my little sister. I wanted to protect her, love her, make her feel better.

I put my arm around her shoulders, pulling her to me. “Well, I’m here for you. Whatever you decide.”

Her hands rubbed at her stomach. “You mean that?”

“Yeah.”

“And what about Mom?” She squirmed. “She’s going to find out. I can’t hide a pregnancy from her. Not her.”

“Well, you’re fourteen. Girls get pregnant at your age.”

“She’ll be so mad.” Her blue eyes trembled as they stared up at me. “She’ll hate me.”

“Mom won’t hate you.” I squeezed her shoulder. “I won’t let her.”

“What do I tell her about the father?”

“That it was a stupid one time thing, and you don’t really know him. He goes to another school, you didn’t catch his name, and you have no way to contact him.” “So I shouldn’t say you’re the father?”

My heart clenched. Panic boiled through my stomach. “Jesus, Jenny, no. She’ll kill me for real. You’re my sister. What we did was illegal.”

“That didn’t stop you from putting your cock in me and fucking me and cumming in me,” she pointed out, her hand resting on my thigh.

“Well, no,” I swallowed. “But you wanted it. You were begging for it.”

“Begging for it?” she arched an eyebrow. “That’s your excuse?”

Panic swirled through my stomach. “I ... I mean. You were consenting. You were the one who fell to her knees and sucked my cock.”

“Relax.” She gave my thigh a squeeze which sent a tingle racing up my leg. “I’m not going to tell Mom.”

I gave a big sigh of relief. “Thanks.”

“I know you think I’m a tattletale.”

I flushed. “Sorry.”

“No, no. I was. I just ... wanted your attention. Ever since I can remember you’ve been my cool, older brother and I wanted to be your wife. I told Mom that when I was five or six, and she laughed. Said it was normal and I’d grow out of it. But I didn’t. When I hit puberty and ... things changed.”

“Developed?” I grinned, my eyes flicking down to her breasts. Her clothing didn’t emphasize them, but I knew they were round and succulent.

“Yes.” Her cheeks were so red. “Well, I wanted to be your wife, but also your girlfriend. Your lover. I ... wanted what happened today so badly. So that’s why I’m always around. I just wanted you to notice me. And when you didn’t, I would get mad and...”

“Tattletale.”

She nodded. “Sorry.”

“So you went out there wanting me to pop your cherry?” I grinned. “You were hoping you’d, what, catch me jerking off instead of vaping.”

“Well, I know you like Ms. Samuels and her big boobs, and you have her right before lunch, and the way she dresses...” Jenny shifted, glancing down at her own breasts. “And every boy in my history class talks about how they want to ‘tap that ass’ as they put it.”

“Well, she does have great cans,” I said, watching her squirm. “But so do you.”

“Really?” There was such a hopeful edge to them.

“Oh, yes, little sis, you have a hot body.”

Her hand stroked higher up my thigh. “James...” She said, her voice tight. “You know ... you already came in me today ... And ... if it’s already too late...”

My dick throbbed. “Yeah, it probably is. So no harm, no fowl if we...”

Her hand reached my cock, rubbing it through my jeans. I ached and throbbed, groaning as she squeezed and relaxed. The pleasure rushed through my body. My toes curled in my shoes as I let out a groan of delight.

“You are a horny minx, sis.”

“Thank you, big brother,” she cooed, squirming. “Will you eat my pussy again? It was so amazing. I came so hard on your lips.”

“Yes,” I groaned. “But first, get naked for me.”

“Here?” She bit her lip, looking around the living room.

“Mom won’t be home for two hours at least. Let me see that sexy bod. Those tits. Show me how much better they are than Ms. Samuels.”

Her grin grew and she let out an excited squeal before throwing her arms about my neck and kissing me hard. Her lips melted against mine, her tongue thrusting into my mouth. I held her, kissing her back, savoring how naughty this was. Her body pressed against mine, feeling the shape of her breasts as she tried to devour my mouth.

My little sister was a horny minx. I loved it.

Her arms tightened, clinging to me with a hungry need. I felt how much she wanted me, how much it meant to her that I was paying attention to her. My dick throbbed in my jeans, aching to bury into her pussy.

But I had to please her first. Clint devoured Alicia’s pussy before he fucked her. And it was clear his little sister would do anything for him. And I think I understood why. He gave her what she needed. He devoured her pussy, made her cum, and let her be his little princess.

Guys I knew just cared about busting their nut. None of them had meaningful relationships. They had girls they hooked up with. Some were almost like real girlfriends, but they would cheat on them if they had a chance. They didn’t care about the girl. Why would they? Modern girls thought they had to put out, that they were emancipated and should just give themselves to the guys because if they didn’t, others would.

And the guys loved it.

Jenny broke the kiss, breaking away from me. “You really think my tits are better than Ms. Samuels?”

“Yes,” I groaned.

“I love you, big brother,” she grinned, her hips shaking as she pulled off her headband. Her brown hair fell about her face and shoulders, sweeping around as she shook her head.

“That’s hot,” I groaned.

She beamed at me, her hips rolling. “You think I’m hot, big brother?”

“Yeah.” My mouth was so dry. “Yeah, I do.”

Her fingers went to the buttons of her dress. “Good.”

I squirmed on the couch, my dick throbbing so hard as I watched her fingers work each button of her dress. My heart pounded in my chest as she revealed her snowy flesh. Then the racy red of her bra. She dressed like a frumpy church wife, but her underwear was so hot, so sexy. It was so shocking to see such a lacy bra, the material transparent in spots, letting her pink areolas and nipples peek through.

She shrugged out of her blouse and wiggled the skirt down her hips, exposing her white tights covering her racy, red panties. They almost were a thong cut. Such a naughty pair of panties. She stepped out of her skirt and turned, showing her ass. The panties only covered the top half of her butt-cheeks before the fabric narrowed into a strip vanishing into her crack and clinging to her pussy.

“Yes,” I panted, rubbing my dick through my jeans as she peeled off her tights, exposing the creamy flesh of her butt clad in those panties. “Those are hot. I love them.”

“My cheekies?” she asked, bending over, the crotch tight against her pussy. She smacked the naked part of her ass. “They’re so naughty. I just had to buy them. It makes me feel so wicked walking around in them and no one knows. No one but you, big brother.”

“Yeah,” I panted as she stepped out of her tights. She was so slim and sexy.

She straightened, reaching behind her and unfastening her blouse. I licked my lips, squeezing my cock so hard through my jeans as she shrugged out of her bra straps. They slipped down her arms, the cups sliding away from her breasts. She dangled her bra to her right, giving me a teasing look over her shoulder before she dropped it.

“Where did you learn to do that?” I groaned.

Her cheeks when crimson. “Um ... porn. And I practiced in my bedroom.”

“Stripping.”

“Yeah,” she said, wiggling her hips, her ass swaying. “For you.”

“Damn, I love it.”

She turned around slowly, her round breasts jiggling. They were a lush pair, ivory flesh bleeding into pink areolas, her nipples small but hard, thrusting at me as she faced me. She trembled, putting her hands on her hips, trying to look sexy, but at the same time there was a vulnerability about her, a fear glittering in her eyes.

“You are the sexiest girl, sis,” I panted. “Damn, I am the luckiest big brother in the world. Your tits are amazing.”

Every word relaxed her, transforming her pose from the vulnerable into the sensual as her confidence swelled. Her smile grew smokier. Her breasts rose and fell as she breathed, the fear vanishing from her eyes, replaced by smoldering desire.

Then she hooked her fingers in the waistband of her panties and pushed them down her hips. I had already seen her pussy when I pulled them off her hips just hours ago, but I still salivated, leaning forward as the first brown curls of her bush appeared. She rolled her panties down farther and farther, exposing more of her pubic hair, and then her slit half-hidden by her curls. I smelled her excitement, a tart musk that only made me harder.

“Now it’s your turn,” she grinned. “Let me see my sexy big brother naked.”

I blushed. “Really? You think I’m sexy?”

She nodded her head, her hands stroking up and down her body. “You are so cute. All my friends whisper about you.”

“Really?” I grinned at her, arching an eyebrow.

“I’m not having a threesome with you and one of my friends,” she told me, eyes narrowing.

“Had to try,” I shrugged as I stood and peeled off my t-shirt.

I played soccer for school and my body was tanned by a summer practicing and playing with my friends. She let out an appreciative moan, licking her lips. I grinned at her as I unfastened my jeans, pushing them down along with my boxers, my cock popping out hard, bobbing before me, my balls aching.

“Tada,” I said, standing naked.

“Come on, let me see that ass,” Jenny purred.

“Girl’s like a guy’s ass?” I asked, glancing down at my dick. “What about my cock?”

“Girls like muscular chests and tight asses. Cocks are okay, I guess.”

“Huh,” I said, turning, letting her stare at my ass. I gave her a booty shake which made her clap.

“Yay, shake that ass!” she cheered, sounding like a guy at a strip club. Then she smacked my right cheek and squeezed it. “I’m so glad I can do this, big brother.”

“Yeah,” I groaned as she pressed against me, her pussy and silky pubic hair rubbing on my butt-cheeks, my cock throbbing as she ground on me.

“You’re all mine.” Her hands slipped around my stomach, rubbing my abs as she ground on me. I straightened my back, her nipples hard against me. Her lips kissed between my shoulder blades.

“And you’re mine,” I groaned, my dick growing hotter.

“Oh, what are you going to do to me?”

“Devour you.” I spun in her embrace, my dick smacking into her hip. She giggled as I seized her, pulling her naked body tight against mine, her breasts rubbing on my chest as I kissed her hard.

I pushed her down on the couch as our tongues wrestled, my cock rubbing on her stomach, throbbing. My sister felt so hot against me. I shivered, my tongue probing deep into her mouth as I kissed her. She was so hot. So lithe. I wanted to fuck her so badly. But her pussy brushed my balls, so hot and wet and in need of her big brother’s attention.

I broke the kiss as she squirmed on the couch. I kissed down her neck, my hands stroking her sides, finding her breasts. I shuddered as I cupped her naked tits, squeezing their firm plumpness. I loved how soft they were. How they felt in my hands.

And how my little sister moaned as my lips reached her nipples.

“Big brother,” she gasped as I sucked on a pink nub.

My tongue explored her nipple. The texture felt delicious on my tongue, winkled and silky at the same time. I sucked hard, making her buck and shudder. I nibbled on it, doing everything I remembered from porn. I sucked so hard, taking as much into my mouth as I could while my fingers played with her other nipple.

I pinched and rolled the little nub. I loved the sounds my sister made. She gasped and moaned, squirming, her legs spasming, brushing my naked sides. I squeezed and kneaded her breasts while I played with her nipples. I made her moan and gasp. And that was so hot.

“Big brother,” she kept moaning. It was such a sexy thing to hear. My heart beat faster every time. “Love you, big brother.”

“Love you, too,” I moaned between sucks on her wonderful nipple.

My right hand wandered down her body as I kept playing with her nipple, swirling my tongue, sucking hard, making wet plops every time my mouth popped off. My hand reached her stomach. She squirmed, sucking in a breath as I went lower and lower.

And found the silky curls of her pubic hair.

Her thighs spread wide, inviting, as my fingers caressed her pubic hair. I stroked her silk as I went lower and lower. She grew hotter, wetter. Her flesh was feverish. And then I found her slit. She dripped. Moans sang from her lips as I rubbed her pussy. I stroked up and down her slit, my fingers parting her folds.

I found her pussy’s entrance and penetrated her.

My dick throbbed. This morning, this hole was virgin territory. No one had gone in here before me. I had broken her in. I had taken my sister’s cherry. As her tight snatch clenched on my two probing fingers, my cock ached to bury into her again.

Just pull your fingers out of her and let me fuck her, my cock seemed to say. We’ll both enjoy it more.

I ignored the voice, my fingers pumping into her silky flesh. She was so hot. My thumb slid up her silt and through her curly pubic hair, finding her clit. She gasped, her body bucking as I massaged it, my lips sucking so hard on her nipples.

“Oh, big brother,” she moaned, her voice so throaty. She humped and writhed on the couch as I pumped faster and faster. “Oh, that’s so nice. Oh, you’re such a wonderful big brother.”
