Tempted By My Sister's Boyfriend

"You've got to tell me, princess," he whispered as he tugged on my hair just a tad to draw out a whine from my trembling lips. "Tell me you're desperate enough to rut against my dick and cum in those panties."

Whimpering slightly, I nodded and continued to rock my hips on his cock.

"I... I'm desperate. It feels so good. I don't want to stop." I moaned shakily.

His ragged breath warmed my trembling lips.

"I wanna come just like this, please... please."

I pushed my hips to rut harder, to rock faster. Soft pants and whines spilled from my lips. My mind was hazy as I could only think of chasing that teasing orgasm that was seemingly out of reach.

"As much as I want to have my dick riding inside you right now, you sound so fucking hot to stop," he said. "So, rub against me all you want, princess. Rub until that clit of yours is aching to cum."

How it all started...

My name is Kim. Well, it's Kimberly, but I've always preferred to be called Kim. My Dad, Maxwell Ashford, is the CEO of Ashford Group, a large firm with boring business stuff, but it pays for all our expensive lifestyle. My mum, Vivienne Ashford, on the other hand, is the editor-in-chief for a world-famous fashion magazine, LUXÉ. I have just one sibling, and she's the most beautiful and sweetest sister a girl could ask for. Her name is Genevieve, and she is twenty years old, just two years older than I am, but somehow, I still get treated like a baby.

Genevieve is an extrovert, your typical outgoing, bubbly social butterfly. She is the type of girl that don't have to do too much to get the attention of others. In fact, I admire my sister and have always wished to be like her.

She has beautiful, healthy blonde hair. Tall, curvy, has the most perfect body and skin. It's no wonder that she got the attention of Adrian Thorne, a young, high-profile Formula One racer. Despite being from a wealthy family, Adrian has built a reputation for himself at twenty-two years of age.

I, on the other hand, I'm not as fabulous as her. I am what you would refer to as a dork. Most of the time, people ask me if I'm adopted, cause there's no way I'm an Ashford and I look the way I look. I am very introverted, really shy around guys, and that's why I'm still a virgin and sexually deprived.

Just a few days ago, I secretly purchased some sex toys. A vibrator and a dildo I saw advertised online. But that's not the only secret thing that happened. Lately, my sister has been sneaking her boyfriend into the house through my room. He waits inside my room while Genevieve goes to make sure the coast is clear before he follows her up to her room. I know you're probably wondering why that is, well, my parents are very strict and there's a no boys allowed rule that my sister and I are obligated to obey until we don't live here anymore.

We live in a secluded area in Los Angeles, California. My room is downstairs with direct access to another entrance at the back. Adrian comes in from the back, gets into my room, and waits till Genevieve says it's good to come out, and while he's inside my room, we hardly speak. It's just greetings and nothing else.

Until one day.

One day that changes everything.

It had become a normal routine of Adrian storming inside my room with Genevieve pleading with me to let him stay for a while. But on that day, it was different. Genevieve usually knocks before anything, but this time, she didn't.

Adrian came in by himself without knocking and caught me naked, lying on the bed with my legs spread open. A vibrator on my pussy, and my other hand gripping the sheets tightly as I moaned from the momentum of the vibrator on my clit.

The moment our eyes met, I squirted. I couldn't control it as it was my first time pleasuring myself. I covered my mouth with one palm as I struggled to moan quietly, with the other hand pulling the blanket over my body.

My body trembled, both in pleasure and shame. Adrian had seen me touch myself; he must think I'm miserable, I thought. But I was wrong.

He liked it.

"My goodness... my goodness," I said as I covered myself with a blanket.

"It's okay," he said as he bit his lower lip, his eyes never leaving my body.

"No, it's not okay. You just saw me wet my bed. I'm so embarrassed," I said as I lowered my head.

"It's not your fault," he said as he walked closer.

"Yes, you're right. It's not my fault. It's yours," I jumped off from the bed, the blanket wrapped around my body as I pulled the wet sheets off the bed. "You should have knocked, but for some reason you didn't."

"I'm sorry. It's just that your house is packed, I didn't want to risk making any sound."

"Yeah. It's my grandparents' wedding anniversary in two days, so the whole family is here."

"No wonder Gen said it would take longer for her to come get me."

"What do you guys even do that you have to be here... all the time?" I asked.

He laughed.

"You know what, forget I asked. I'm sure you're up there being naughty."

"Naughty? You mean, fucking?"

I rolled my eyes at him as I went into the bathroom for a quick shower and then into my walk-in closet to pick out some fresh clothes.

"Yeah, I'm not supposed to speak about any of that, but to ease your curiosity because I know you're probably thinking about that now," he chuckled. "Yeah, you could say we do it."

"That's both your business. I don't really care much about sex." I walked back into my room, cleaned and dressed up.

"If you don't care about it, why do you have these sex toys lying around?" he smirked.

I hurriedly picked up the toys and threw them in a cabinet in my walk-in closet. "Oh, my goodness! Take your eyes off that."

"It's not a bad thing, Kim. You don't have to be ashamed of it," he said as he sat on the chaise lounge. "Besides, you probably do it with your boyfriend, so what's new?"

"I don't have a boyfriend."

"I don't believe it. You're a very beautiful girl, and I'm sure there are a lot of guys who want to date you."

"And yet, here I am. Still very single and alone."

Adrian's expression changed. It was like as if he was sad, or maybe he pitied me. I don't know what it was, but whatever it was, it made him leave the lounge chair to come sit closer to me.

"That doesn't mean you're not beautiful. You are the most beautiful girl I have ever had the opportunity to meet," he smiled.

"You're probably mistaken me for Gen, but thank you. That's very sweet of you to say."

He paused for a while as he stared deep into my eyes.

"Most times, I wished it was you instead."

"What do you-"

A knock came, interrupting me mid-sentence.

"Come in, Gen," I answered.

Genevieve rushed in, ran up to Adrian, and jumped into his arms.

"Let's go," she smiled. "Thanks, baby sis."

I sat on my bed watching them leave as I thought about what Adrian meant by 'most times, I wished it was you instead.'

And since that day, nothing has ever been the same.

My relationship with Gen hasn't been one deemed sister's goal worthy. I mean, on the internet, we look like we have the best relationship, but things are not what they look like. Gen has been nothing but nice to me, but I have always been excluded from her social life. So, when she asked me if I was interested in going to see a movie with her and Adrian, I was genuinely amazed.

But of course, I said yes.

"Well, okay. Get ready, we'll be leaving in a few minutes. Adrian will meet us at the cinema," Gen smiled.

"Thanks, Gen," I said, hugging her.

"Save it for Adrian," she said.

"What do you mean?" I asked.

"He was the one who requested you join us, and he sent me to ask if you would be interested in coming with us," she answered.

And of course. It wasn't Gen's idea, but it was nice to be included.

"I guess I'll thank him when I see him then," I said as I turned to get changed.

"Oh!" she exclaimed. "Please, look good."

I nodded but didn't say anything. I knew I wasn't going to be able to come with her if I looked weird. I got dressed in a simple floral dress. Hopefully, Gen approves. We got out and parked at the front gate, was Gen's Aston Martin DB11 Volante.

"Do you have your license for this thing?" I asked, grinning as she started the engine with a low purr.

She smirked. "You don't ask a goddess how she flies."

The car eased out of the gate with grace as we hit the Pacific Coast Highway. Twenty minutes later, the DB11 glided into the underground parking garage of the Crescent Cinema, a boutique movie house in West Hollywood known for its velvet recliners and vintage champagne at the concession stand.

Genevieve parked without a word, stepped out, and handed her key to the valet with a wink.

"Don't scratch it," she said, tossing a smile over her shoulder.

The valet swallowed hard, already blushing. "Y-Yes, Miss Ashford."

As we walked through the lobby, moviegoers glanced up. A few whispers, a few not-so-subtle phone cameras. The Ashford sisters were impossible to ignore.

I leaned closer. "Are you sure he's even here yet?"

But Gen didn't answer; she probably thought she didn't have to. As we turned the corner and walked into the private screening lounge, Adrian was already waiting there.

He stood near the wall-length glass window, arms crossed, dressed in charcoal gray sweatpants with a crisp white tee underneath a black sweatshirt and paired with white sneakers. His bright brown eyes flickered towards me and paused on Gen.

"You're late," he said, smirking.

Gen arched a brow. "You're early, and underdressed."

"Didn't realize this was a fashion show," he said as he stepped forward and kissed Gen on the cheeks.

"Thank you, Adrian, for inviting me along," I smiled.

"Glad you accepted."

In just one snap, Gen pulled him closer to her. I turned away, pretending to study the vintage film posters. I didn't want to see how my sister softened under his touch, or how easily he made it look like she was the only one that mattered.

I faked a cough. "Okay, we get it. You're in love. Can we watch the movie now?"

Adrian chuckled. "Sure... The movie."

Adrian and Gen walked up to the back as they sat comfortably, while I sat at the front.

"Hey, Kim," Adrian called.

I turned. "Yeah, what's up?"

"Why are you sitting there? Come sit here," he demanded.

"I felt you love birds will need the space," I chuckled.

"Watching will be better from here, so come up. Sit with us," he said.

"Gen? Is that okay with you?" I asked.

"Yeah, whatever," she answered.

I walked up to them. Gen sat at his right-hand side while I sat at the left, with him sitting in the middle. I looked over to them, and Gen had already wrapped herself in his arms.

A few minutes into the movie, I felt a touch. It was so soft and gentle that it made me quiver. I looked down at my thighs, and Adrian's hand was resting on my thighs, with his fingers tracing my skin.

I remained silent as I glanced up at him, and our eyes met. He had a soft smile on his face as he turned back to watch the movie. I removed his hand from my thighs as I returned to the movie, but I couldn't ignore how his touch made me feel, and how I wanted him to do it again.

Moments later, the movie ended. I rushed out of the lounge, not because I was in a hurry to get home but because Gen was locking lips with Adrian. A few minutes later, they walked out holding hands.

"Wow, Gen. You never cared to give me a heads up before you do the nasty," I frowned.

"You're just pissed because you don't have a boyfriend," she said.

Just then, her phone began to ring. She pulled her phone out from her purse as she notified I and Adrian that she would be right back, leaving us alone once again.

Adrian turned towards me as he gently pulled me back into the private screening lounge.

"How was the movie?" he asked.

"It was fun until you and my sister had to ruin it with your kiss. Like, don't you guys ever chill?" I shrugged.

Adrian laughed. "I see. The problem is the kiss, right?"

"Duh!"

"Did I mention you look really beautiful in your dress?"

"Aww. You think so?"

"Kim," he grabs me gently just above my elbow. "You are beautiful."

"Thank you," I said, trying to hold back my smile.

We both stood there, alone in the lounge, our eyes never leaving each other's. He smirked as he grabbed my waist and pulled me closer to him, his hands tracing the curves of my body.

"How do you feel about me holding you like this?" he whispered into my ear.

I swallowed hard as I tried to control my body from trembling at the sound of his soft voice.

"Can you be honest with me?" he asked.

"What do you want to know?"

"Do you want me to stop?"

"I... I don't know what to say. You're my sister's boyfriend."

"Do you want me to stop?"

"Adrian-"

"Just answer the question, Kim. Do you want me to stop?"

I looked around, my body still trembling from being so close to him. "It's weird, but I don't want you to stop."

He grinned as he patted me on my head, his hands now inside his pockets as he walked out of the lounge. I fell on the recliner seat, trying to control my breathing. Adrian is the first guy who's ever been this close to me and the first guy to ever touch me intimately.

I knew it was wrong, but God, did I love every bit of it. Since the first day I saw Adrian Thorne in person, I've developed a crush on him. I yearned for his attention, but my sister got it first, and without stress. They ended up dating, and the only time I saw Adrian was when he would hide inside my room till Gen came.

I always fantasized about him being with me instead and doing the things he does with my sister with me.

The first day I decided to try out the vibrator I bought, I visualized myself with Adrian, and as if it was fate, he came into my room. Now I can't stop thinking about him.

There was something in the way he looked at me sometimes. The way my heart thudded sometimes when he looked at me, or how warm his voice felt in the space between my ribs. But he's not mine.

"Kim!" Gen called out, snapping me away from my thoughts. "What are you still doing in here? Let's go."

"Yes, Gen."

It's my grandparents' anniversary today, and the whole house is in a frenzy. The Ashfords have always been known for throwing the best parties. I'm sure we're killing it again this time around, but my thoughts remained on Adrian.

The house shimmered in the after sun with extended families, like my aunties, uncles, and cousins from London, New York, even Monaco, all gathered to celebrate the 50th anniversary of Charles and Miriam Ashford, the patriarch and matriarch of the Ashford empire.

Upstairs in the family sitting room, a quieter space away from the crowd, Gen and I lounged on the cream velvet couch, our heels off, and our hair curled to perfection. Mum and Dad stood by the floor-to-ceiling window, glasses of champagne in their hand.

Dad, even in a casual moment, cut an imposing figure. Dressed in a charcoal grey suit, tie loosened. Mum looked effortlessly as usual, wearing a high-neck ivory dress, sleek chignon, diamond cuff earrings that caught the very light.

"Your grandmother's asking about the piano duet, Kimberly," Mum said, looking over her shoulder. "You haven't forgotten the notes, have you?"

I grinned, half-nervous, half-playful. "I'm pretending to forget them. It adds drama."

Gen laughed. "You'll be brilliant. Like always."

Dad stepped away from the window, his eyes on Gen and me. "You know, I barely see either of you these days. Always school, always something."

"You're one to talk," Gen teased. "You live at your company headquarters."

Mum sighed with a smile. "Touché."

There was a brief, comfortable silence until Gen broke it.

"Actually," she said, smoothing her silk dress. "I wanted to ask something. About tonight."

Dad raised an eyebrow. "Let me guess. You're planning to sneak out tonight before dessert?"

"God, no. I love Grandpa's toast." Gen said, then hesitated. "But... I was wondering if I could invite someone. A friend."

Mum's gaze sharpened slightly. "A friend?"

Gen nodded, carefully. "His name is Adrian Thorne. We've been seeing each other for a while. He's smart, respectful, polite, and he races professionally."

Dad's face didn't shift, but I felt the air thicken just a little.

"A racer?" he repeated.

"Formula one," Gen clarified. "And he's studying business too. He's not just fast cars and adrenaline."

Mum pursed her lips, considering. "The Thornes. I know that name. Weren't they at the Monaco gala last spring?"

"Yes," Gen answered quickly. "His father is Michael Thorne... but Adrian's different. Not obnoxious and not entitled."

Dad exchanged a look with Mum. The kind of look parents give when they're weighing between instinct and trust.

"You vouch for him?" Dad asked, finally.

"Yes, I do," Gen answered quietly. "He's important to me."

I said nothing, just watched. My fingers curled into the fabric of my dress.

Mum took a sip of her champagne, then nodded once. "One friend. One Adrian. He may stay for dinner, but he wears a jacket and must speak to your grandparents."

Gen smiled, slowly and gratefully. "Done."

Dad leaned down to kiss the top of her head as he walked out with Mum, both holding hands.

I turned to Gen. "You've finally spoken to Mum and Dad about him."

"Yeah," she smiled. "Now, no more sneaking in."

"You think it's that easy? You only granted him an invite to the event, it's not like he's part of the family now."

Gen chuckled. "This is just the first step, little sister. Well, I'd better go inform him."

** ** ** ** ** ** ** ** **

The garden had never looked magical. Golden fairy lights twisted through the canopy of trimmed trees, their soft glow catching the shimmer of crystal glassware and silk gowns that dotted the open space. Elegant laughter and quiet conversation floated through the air, blending with the soft melody of the live artist performing near the reception area.

I stood quietly near the edge, close enough to see the guests enjoying the show, but far enough to let the cool evening breeze brush over me. My fingers still tingled from the keyboard. The final note of my performance for Nana and Papa Ashford still echoes faintly in my head like a memory. They'd smiled so brightly, their hands clasped with pride. It was everything I'd hoped for.

And yet... even in the midst of all this beauty, I felt something unsteady beneath my ribs. My eyes scanned the crowd unconsciously as I looked for Adrian. Seeing him beside Gen when I played the keyboard for my grandparents made me uneasy. Still, he wasn't in the crowd. He wasn't seated beside Gen anymore. Has he left? I thought to myself, and that's when I turned and just like that, I bumped into someone, spilling my drink all over my dress.

"My goodness!" I exclaimed as I looked up, surprised. "Adrian?"

"I'm sorry, I didn't mean to bump into you," he apologized.

"It's fine, Adrian. I know you didn't mean to. It's just a beautiful dress and you've ruined it, and that's the only thing I'm sad about," I sighed, walking out of the reception area and to the other side of the garden.

"Kim," he shouted, following me. "Where are you going?"

"Anywhere but there. I can't let the others see me like this. A mess," I lowered my head.

"But you can change your dress, can't you?" he asked.

"I can, if I have anything this good to wear. Mum handpicked this dress for me, and it's the only one she brought. You know I'm not good at fashion like the rest of my family," I sighed. "Besides, why were you all the way over to the end of where I stood? Weren't you supposed to be with Gen and my grandparents?"

"I know," he said.

"Gen put in work to have you invited, and you just abandoned her there. Plus, you were supposed to meet with my grandparents; it was a deal made between Gen and my parents for you to come to the party," I said.

"I'm going to be honest with you," he said, his voice soft. "I only accepted Gen's invitation because I wanted to see you again. That's why I left her table with your grandparents to look for you. But I bumped into you, and I'm sorry. If this is the only dress you have, we can go out and I'll pick something even better than this for you, and you'll be the belle of the ball, looking better than everyone in there. Trust me."

I sat on the grass, my legs crossed over each other. "Thank you, but I don't think I want to get back there. It was boring anyway."

"I loved your performance. I didn't know you played the keyboard," he said as he sat down beside me.

"I used to take classes. Turned out to be the one thing I'm better at than everyone else in my family," I chuckled. "I'm proud of that."

"You look beautiful when you're happy," he said, his eyes never leaving mine.

"Adrian-"

"Please, let me adore you," he said, his hands softly placed on my thighs.

"It's weird how much I like the attention you give and have been giving me lately, it's more than anyone has ever given me. But you're Gen's boyfriend, and I don't want to get in any trouble with my sister," I said.

"You won't get into any trouble if you don't tell her. I know for a fact that I'll keep this a secret for as long as you want, not because I care about what your sister might feel towards this, but because I care about how badly it will affect you and I don't want to put you in an uncomfortable situation," he said, his hands now on my face, his fingers softly caressing my cheek.

"Adrian-"

"I know you want this. Stop holding back," he smirked.

"Adrian-"

We sat there in a silence so heavy it nearly pulled me under. But I couldn't look away from him. Not with the way he looked at me, like I was a truth he hadn't known he needed. Like I was something sacred and wrong all at once.

"I've tried," he said. "I've tried so hard."

He took a step closer, and I didn't move. My heart thundered as his fingers brushed mine. It was the softest touch, but it sent a tremor up my spine. He reached up, cupping the side of my face, his thumbs tracing my cheek like he was memorizing it. I could've stepped back. But I didn't.

His lips met mine in a kiss that was slow and uncertain at first, tasting of hesitation and all the things we weren't supposed to feel. But then it deepened, just slightly, like something breaking loose.

It was my first kiss.

And it burned with everything I was never meant to want.

When we pulled apart, the world came rushing back in, loud and real.

"I-I can't," I whispered, breath shaking, eyes stinging.

And before he could say anything, I turned and ran.
