Can You Keep A Secret? (Parent!Levi x Reader Modern AU)

(BEING REWRITTEN; WILL POST REWRITE WHEN FINISHED)
Let's pretend for a moment that Levi is a single dad to Eren and Mikasa. He's usually a pretty chill dad, allowing Eren and Mikasa to go to parties and come back trashed. He also can be kind of cocky and finds amusement in your antics frequently. Eren, Mikasa, and You are all in college and 21. You live on your own, but Eren and Mikasa decided to live with Levi while you all go to school together.

What neither of you realized was how bad you wanted each other and when you finally get together, you put yourselves in quite a bind.

This WILL contain limes and lemons (or smut if you are unfamiliar with such terms) so there's your warning. This also features a daddy kink, but it isn't the main part of the smut. Fair warning: the smut can be a little rough.

If I think of anything else, I'll add it as I go.
