Tempted By My Sisters 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."
