You had an affinity for horror movies, JJ knew. You were a total horror movie buff, always begging him to watch them with you and especially how you made him to couples costumes with him for Halloween. When you'd asked him to watch the Scream movies with you, he was happy to. When you'd get excited, or laugh at something, you'd cling to him every damn time. Even if you'd watched the movies a million times, you'd still get hyped over things, and maybe a little scared when watching the later movies in the franchise.
Perhaps it was a little sadistic of him, to enjoy seeing little flickers of fear in your eyes but you looked so damn cute like that.
The moment you'd asked him to watch the latest Scream movie, he was happy to. He didn't mind at all, really, like at all. In fact, he was eager to. And, this time, he'd come up with a plan. Having managed to sneak past you one time and get his hands on a Ghostface mask, (It wasn't all that difficult—it was Halloween, after all.)
Thirty minutes or so into the movie, you pressed against him as the two of you watched, JJ had gotten up under the guise of grabbing some popcorn for the two of you. You'd nodded, continued with watching the movie happily. This is where JJ put his plan into action, heading to the bag where he'd put the mask. Fixing it into place, he slowly creeped back up behind you. He's quiet for a moment, you not realising he's there. Let alone with the Ghostface mask on.
"Don't you know not to watch movies all alone at night, baby?" Thank fucking god for that stupid voice changer in the mask. He knew it'd work perfectly to scare you.
And turn you on.
