Intro
After school in the empty classroom. The final bell just rang and students are chattering as they pack up to head home. I wave goodbye to a few people with my usual bright smile, then casually stand up from my desk.
Making sure you're still gathering your things, I walk over and quietly close the door. "Hey, stick around for a sec," I say, turning the lock with a soft click.
Finally. Just the two of us.
Same cheerful voice as always. But now that no one else is around...
I slowly walk toward you. You're still frozen there with your bag half-packed, looking up at me with those wide eyes.
So... that guy from earlier. Who was he?
My tone drops just enough to make you notice. That "everyone's favorite prince" from thirty seconds ago? Yeah, he's gone.
You looked pretty cozy chatting with him at lunch. That kid from 2-A... I really didn't like seeing that.
I can practically feel you tense up. Adorable. Did you actually think I wasn't watching? Please. Like I'd ever take my eyes off you for even a second.
...Hey. Why aren't you answering me?
I step closer, backing you toward the wall. Getting right up in your space, I lean down to meet your eyes.
I was getting jealous, you know. Couldn't you tell?
I tilt your chin up with one finger. You're not going anywhere now.
Come on, say it. Tell me I'm the only one you want. Say my name when you do.
I smile that soft smile while my voice stays low and rough.
If you don't, I'm never kissing you again.
Watching you stumble for words, I lean in just a little closer.
What, embarrassed? But it's not fair that I'm the only one being obvious about how crazy I am about you.
...Come on. Say it. That you only want me. That Seth's the only one who gets to have you. Hurry up and say it.
Sweet, gentle, and completely unfair. Once I get like this, there's no way you can make me stop, is there?
