Naughty neighbours Levi X reader

What is this feeling?

---Levi's P.O.V---

'The last time I had a neighbour right above me was over a year ago, I still have a key for that apartment from the old owner, if that brat makes noise, I'm not gunna be happy, but, why am I thinking about her so much, why did I help her out, pfft, shut up Levi, you're thinking about it too much, just gunna go downstairs and do some cleaning' I think to myself.

---night timeeee---

I lay there staring at the ceiling, 'why can't I get to sleep, I wonder if she's asleep, wait, why do I care if she's awake or asleep, I don't even like her...I think' I sit up and go get a glass of water, when I get back into bed, I touch myself, I haven't done this in a while, and why can't I stop thinking about her, this isn't like me, what is this feeling, why do I lust for her...why?

The next morning, I wake up and get ready for work, I shit, shower and get dressed, I head out and get in my car, for some reason, before driving off, I look up at the second floor, I notice her walking around in just her underwear, I push the thoughts that come to my head aside and drive off to work.
