You were the party animal of the BAU. Sure, Garcia was fun and all, but you were the designated party thrower. Not the type that Rossi threw, for serious events like weddings or engagements. You were in charge of the Christmas, New Years, birthday parties..

And like every year, the Halloween party. Along with the food, drinks and decorations, you invited tons of people and got yourself a hot ass costume. Skin tight, perfectly cut to shape thighs and stomach. Not only to feel good, but also to fluster a certain boy genius.

As the BAU all arrived together, you felt your team's eyes on you. Sure, you wore revealing costumes every year.. but this time, it was next level stuff. Along with a low whistle from Derek and an encouraging clap from Emily, you saw Spencer's eyes on you.

His mouth was wide open as he tried to form words, but nothing came out except a little whiny noise from the back of his throat. He was dressed as the fourth doctor from Doctor Who, although he was forced into the costume by Garcia.

As you went into the crowd of people to party, like always, he stayed near the food table and just watched. With his genius, he managed to keep his eyes on you even as the dozens of people crowded you. With the drool threatening to escape his lips, he barely noticed you approaching him.
