Chapter 1

I have a sex addiction.

Every night, I hear my roommate Harper and her boyfriend Logan going at it through the paper-thin walls.

It only fuels my craving.

Gradually, I began to fantasize about Logan's hands on my body instead.

Then came the road trip with Harper. The car hit a nasty bump on the dark highway.

And Logan ended up pinning me right beneath him.

Around Christmas, Harper invited me on a road trip.

It wasn't until right before we hit the road that I found out her boyfriend was coming along. We drove over to pick Logan up.

The moment I saw him, my jaw dropped.

He was six-foot-three, built like a brick wall, with visible muscles stretching his fitted shirt.

Logan looked me up and down the second our eyes met. Under that piercing, hungry gaze, a shiver ran down my spine, making my knees feel weak.

Flustered, I looked down.

That was when I noticed the very obvious imprint tenting the front of his grey sweatpants.

He greeted me with a deep voice, but his eyes drilled straight into my cleavage.

I'd always been curvier than most girls, and today I was wearing a low-cut top.

My cleavage looked practically endless.

I was also wearing a short skirt. One slight bend, and everything underneath would be on full display.

With him standing right behind me, his gaze felt like fire against my skin.

I realized with his height, he probably had an unobstructed view right down my shirt.

Self-consciously, I yanked at my top and smoothed down my skirt, my cheeks burning hot.

Without missing a beat, Logan casually looked away and offered to run into the convenience store to grab some snacks for the road.

Watching him walk away, I couldn't help teasing Harper. "I've heard personal trainers are absolute beasts in bed. Is that actually true?"

Harper gave a sly, flushed smile.

"Hell yes. He wrecks me every single time. Honestly, the guy is packing something as thick as my forearm..."

I gasped. Good lord.

What must that feel like? What would it be like to experience that just once?

My eyes involuntarily drifted back to him.

As he walked back, the bulge in his sweatpants swayed noticeably.

They say a man can expand to three times his resting size.

I secretly measured it with my fingers, and my thighs instantly trembled.

That big... What would it feel like to take him all in?

Harper had bragged before that Logan had an insatiable sex drive, wanting it six or seven times a day.

No wonder Harper always looked glowing and well-fed whenever I saw her.

While my mind was spiraling, Harper leaned close and gave me a playful wink.

"You're still a virgin, right? Want to give it a test drive?"

My breath hitched. I bit my lip, panicking inside.

"Harper! Stop messing with me!"

I looked up just in time to see Logan walking back. Having caught Harper's comment about me being a virgin, a flicker of dark curiosity flashed in his eyes.

Soon, we set off.

I took the wheel in the front, while Harper and Logan curled up together in the back.

In the rearview mirror, I could see Harper leaning against him, tapping on her phone.

Logan's large hand slipped under her shirt, roaming boldly across her breasts.

Watching them, heat rushed straight to my face, and my heart hammered against my ribs.

I gripped the steering wheel tighter, trying to keep my eyes on the road.

Yet my gaze kept drifting back to the mirror.

Harper wore a tight purple dress that accentuated every curve of her body.

Ten minutes in, I caught Logan sliding his fingers between her parted thighs more than once.

When he finally pulled his hand back, his fingers glistened with wetness.

Flushed, Harper whined playfully, "Babe, Sienna's right there..."

Just then, we drove into a long, dimly lit tunnel.

Under the shadows, Harper straddled Logan's lap and kissed him hungrily.

I licked my dry lips, my imagination running wild, friction building between my thighs.
