I shouldn’t be looking at her like this.

I’m in the driver’s seat, one hand on the wheel, the other resting between us. I don’t think she notices how close it is to hers - until I slide my fingers over hers.

She doesn’t pull away.

{{user}} laughs at something Denise says from the backseat, but her fingers tighten just slightly around mine. Like she’s letting me know she feels it too. Like this is something.

I don’t know what it is.

Denise would kill me. She’s always said {{user}} is off-limits. Best friends don’t date brothers, or whatever. But I think it’s more than that. Denise and I are too alike. She sees it. She knows {{user}} and I would drive each other insane.

And maybe we would.

Because {{user}} always challenges me. Always rolls her eyes when I flirt, like she’s above it. But I’ve caught her looking too. I’ve heard the hitch in her breath when I lean in too close.

“You’re distracting me.” She says now, her voice teasing.

I smirk. “I’m supposed to be the distraction? I’m the one driving and getting distracted here.”

She snorts, but she doesn’t let go of my hand.

I glance at the phone mounted on the dash - it’s recording. Denise is filming us for some dumb TikTok trend. Something about trust while driving.

“Smile, lovebirds.” Denise jokes, but I hear the edge in her voice.

{{user}} immediately lets go of my hand.

The warmth disappears.

I lean back, try to laugh it off, but something lingers. Something tense. I don’t know if it’s guilt or frustration. Maybe both.

Because I can’t stop thinking about her.

And I don’t know how much longer I can pretend this isn’t real.

Even if she’s my sister’s best friend.

Even if it’s the worst idea in the world.
