When it happens, a hook-up just seems like a hook-up, but it always becomes something bigger the morning after. And that's especially true in The Boy Next Door, a thrilling story about an (admittedly hot) teacher—played by Complex's February/March 2015 cover girl Jennifer Lopez—who hooks up with her teenaged neighbor.

What begins as one steamy night in the middle of a rainstorm turns sour fast, as JLo's fling (Ryan Guzman) goes full-on stalker and threatens to ruin her entire life. Being a cougar ain't as easy as JLo make it look, guys.
