My Brother’s Best Friend Wants Me

Adrian's POV

Kissing Sienna was a damn mistake.

Now I knew exactly how she tasted. And there was absolutely no way in hell I was surviving that knowledge peacefully.

The inside of the car felt too small now. Too hot.

Sienna sat beside me breathing slightly unevenly while rain hit the windows softly around us, and all I could think about was dragging her back into my lap and kissing her again.

Dangerous thoughts.

Very dangerous.

Especially because she looked completely unaffected right now.

Well.

Almost unaffected.

Her lips were swollen from me.

Cheeks flushed.

Hair slightly messy from my hands.

But somehow she still managed to look at me with that dangerous little expression like she knew exactly what she’d done to me.

That cocky look nearly pissed me off.

In the hottest way possible.

“You’re staring again,” Sienna murmured softly.

I leaned back against the seat slowly. “You’re smug now.”

One corner of her mouth lifted immediately.

“I think I earned it.”

Jesus Christ.

That confidence on her was going to ruin my fucking life.

“You really enjoying this?” I muttered.

“Yes.”

Too fast.

Too honest.

My jaw tightened.

Sienna tucked one leg slightly beneath herself as she turned toward me more fully in the seat.

The movement dragged my attention lower for one dangerous second before I forced myself to look back at her face.

Barely.

“You know what your problem is?” she asked quietly.

I laughed once. “Pretty sure I have several.”

“You act like you’re in control even when you’re clearly losing your mind.”

My eyes narrowed slightly.

Dangerous answer.

Because she wasn’t wrong.

That was the problem.

I was losing my fucking mind.

Over Ethan’s little sister.

A girl I was supposed to protect.

Ignore.

Stay the hell away from.

Instead I was sitting in a dark parking lot trying not to drag her on top of me again after kissing her like I’d been starving for it.

Which honestly?

I had been.

For years.

“You should stop looking so pleased with yourself,” I said quietly.

“Why?”

“Because it makes me wanna do something stupid again.”

The heat in her expression deepened instantly.

Fuck.

There it was again.

That look.

That soft dangerous look like she liked hearing me lose control over her.

Sienna shifted closer unconsciously.

Or maybe consciously.

Honestly I didn’t know anymore.

And I definitely didn’t trust her innocent act right now.

Not after the way she kissed me back.

Not after the sounds she made against my mouth.

Jesus Christ.

My self-control was hanging by a thread.

“You regret it?” she asked suddenly.

The question hit me immediately.

Not playful this time.

Real.

I looked at her properly.

And suddenly she didn’t look smug anymore.

She looked nervous.

Like my answer actually mattered to her.

That realization hit harder than expected.

“No,” I answered instantly.

Too instantly.

Sienna’s eyes searched mine quietly.

“Then why do you keep acting like the world is ending?”

I dragged one rough hand down my face slowly.

“Because your brother would probably kill me.”

That made her laugh softly.

And fuck.

I felt that laugh somewhere directly in my chest.

“He trusts you too much for that.”

“That’s exactly the problem.”

Her expression softened slightly.

Then suddenly her fingers brushed lightly against my jaw.

My entire body went still instantly.

Jesus Christ.

That tiny touch affected me way too much.

“You know,” she murmured quietly, “you get scary when you’re jealous.”

I grabbed her wrist gently before she could pull away.

“Ryan still bothering you?”

Her eyes widened slightly.

Then she laughed again.

Warm.

Dangerous.

“Oh my God,” she whispered. “You’re still thinking about him.”

I stared at her blankly.

“Sienna.”

That only made her smile wider.

“You really hate him.”

“I don’t hate him.”

“You definitely hate him.”

“I hate the way he looks at you.”

The words left my mouth before I could stop them.

Silence filled the car instantly afterward.

Shit.

Sienna stared at me for a second too long.

Like she wasn’t expecting honesty that direct.

Then slowly—

very slowly—

her thighs pressed together.

Fuck.

I noticed immediately.

Of course I did.

And judging by the way her cheeks heated slightly—

She realized I noticed too.

The tension inside the car thickened instantly.

“You notice everything, don’t you?” she whispered.

My eyes stayed on her for another second before I answered quietly,

“With you? Yeah.”

That look again.

That dangerous soft look she got whenever I stopped pretending.

I should’ve looked away.

Instead my hand slid from her wrist slowly upward along her arm.

Feeling her shiver beneath my touch instantly.

Jesus Christ.

“Sienna.”

The way her name came out rough made her breathing change immediately.

God.

This girl reacted to me so openly.

So honestly.

And it was becoming addictive in the worst possible way.

“You keep saying my name like that,” she whispered.

“Like what?”

“Like you’re trying not to do something.”

I laughed quietly.

“That obvious?”

“Yes.”

Her voice softened slightly.

“And I think you’re losing.”

That did something dangerous to me.

Something hot.

Because she sounded pleased about it.

Not scared.

Not hesitant.

Pleased.

I stared at her mouth again.

Big mistake.

Because now all I could think about was kissing her harder.

Slower.

Longer.

The memory of her breath catching against my lips flashed through my head instantly.

Fuck.

My restraint snapped dangerously low.

“Come here,” I muttered roughly.

Sienna blinked once.

“What?”

“You heard me.”

Her heartbeat visibly quickened beneath the soft fabric of her shirt.

I watched it happen.

Watched her breathing shift.

And somehow that only made me want her closer.

Dangerous.

Very fucking dangerous.

Slowly, Sienna moved toward me across the seat.

Close enough now that I could smell her again.

Vanilla.

Rain.

And something dangerously feminine that was becoming permanently attached to my brain.

She stopped inches away.

Probably waiting for me to move first.

Smart girl.

I grabbed her waist immediately.

A soft surprised breath escaped her lips as I pulled her fully onto my lap.

Jesus Christ.

The second she landed against me, every rational thought in my head disappeared completely.

Warm.

She was so fucking warm.

Her eyes widened slightly while one of my hands tightened automatically against her waist to steady her.

“You really are losing your mind,” she whispered breathlessly.

“You noticed?”

Sienna tried hiding a smile.

Failed badly.

And somehow her sitting in my lap felt both incredibly wrong and way too natural at the same time.

My hands stayed firmly on her waist while she looked down at me with flushed cheeks and swollen lips.

This was bad.

Very bad.

Because now I understood exactly how easy it would be to become addicted to touching her.

The realization barely settled before my phone suddenly started ringing loudly through the car.

Reality crashed back instantly.

I closed my eyes briefly.

“You’ve gotta be kidding me.”

Sienna burst into quiet laughter immediately.

And fuck.

Even laughing she still looked too pretty sitting on my lap.

The screen lit up against the dashboard.

ETHAN.

Of course.

Sienna looked at the screen.

Then at me.

Then her smile turned dangerous.

“Oh this is evil,” she whispered.

“Don’t start.”

“You answer it.”

I stared at her.

“You are literally sitting on me right now.”

“That sounds like a you problem.”

Jesus Christ.

I almost laughed despite myself.

Then Ethan kept calling.

I exhaled slowly before finally answering.

“What?”

“You sound annoyed,” Ethan said immediately.

“No shit.”

Sienna pressed her lips together hard trying not to laugh.

Traitor.

“Did you pick Sienna up already?” Ethan asked.

I looked down at the girl currently sitting in my lap trying not to smile.

“Unfortunately.”

Sienna immediately smacked my chest lightly.

Ethan laughed through the phone. “Sounds about right. She annoying you already?”

“You have no idea.”

Now Sienna was fully biting back laughter against my shoulder while I tried keeping my voice normal despite the fact that her thighs were pressed against me.

Dangerous fucking situation.

“Just bring her home before she starts a fight with somebody,” Ethan muttered.

“Working on it.”

“Cool. I’m ordering food.”

The call ended a second later.

Silence immediately filled the car again.

Then Sienna looked up at me innocently.

“You called me annoying?”

I stared at her for a second.

“You’re sitting in my lap while I talk to your brother on the phone.”

Her cheeks turned pink instantly.

“Still,” she muttered.

My hands tightened slightly on her waist.

“Still what?”

“That was rude.”

I laughed quietly despite myself.

And honestly?

That was probably the real problem.

I was starting to enjoy this way too much.
