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, am not as fabulous as she is. 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 no longer live here.

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 as if he were 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.
