"Trick-or-treat!" the children shouted happily as they approached John. He stood, smiled, and handed out the candy to a chorus of thank you's. Then the kids smiled and moved on down the street.

John Watson sat back down in his foldable chair he had set up on the sidewalk in front of 221B. It was Halloween, and John had dressed up in a full Frankenstein costume to pass out treats. He loved Halloween, and he loved making the children happy.

Just then his phone beeped. He had a new message. He texted back and forth with Sherlock while he handed out more candy.

Why are you doing this?

-SH 8:43 PM

Doing what?

-JW 8:43 PM

Dressing up like a child and participating in this foolish holiday?

-SH 8:43 PM

It's fun. It's fun to dress up, it's fun to celebrate, it's fun to make people happy.

-JW 8:44 PM

Oh.

-SH 8:44 PM

Why are you asking, Sherlock?

-JW 8:45 PM

John received no reply to this text. He should have expected it, Sherlock didn't understand emotions, or the reasons people did things.

Just then, John heard the door to their flat open and close behind him. He expected Sherlock to walk around in front of him, but instead he felt hot breath on his neck.

"I want to suck your blood." Sherlock said deeply. Sherlock giggled in his deep baritone voice and John laughed with him to cover the gasp that nearly escaped his throat. Sherlock whispering into his neck made him tremble slightly, a shutter shot through his spine. Sherlock placed a chair next to John's and sat down next to him.

He was dressed as Dracula.

John smirked at Sherlock.

"So what convinced you to dress up?" John asked.

"Well," Sherlock looked at the ground, at the sky, and at buildings across the street as he drummed his fingers against his leg. He looked at John, "It makes you happy."

John hoped that the green makeup on his face covered up his blushed cheeks. Sherlock, the emotionless machine who didn't understand feelings, had dressed up simply because it made John happy. This feeling warmed John to his core, to be valued so much by another human being.

"And I look pretty sexy in this costume." Sherlock added with a grin.

John scoffed at Sherlock's comment, it was unlike anything Sherlock had ever said before.

Of course, John silently agreed with his statement.

Sherlock's costume consisted of a vampire cape that mirrored the high upturned collar of his wonderful coat, and a low cut black v-neck shirt that displayed his muscular chest. It also looked like Sherlock had put on make-up to make his face paler, which contrasted his eyes and seemed to make them shine like moonlight. The light from the street lamp shadowed Sherlock's face and accentuated those perfect cheekbones and gorgeous lips.

Yes, John wholeheartedly agreed.

Sherlock looked at John in a way that he hadn't ever looked at him before, and John realized that he must have broadcasted these thoughts all over his face.

Before John could fully process what was happening, Sherlock had leaned forward in his chair and had positioned himself inches from John.

"Oh, so you agree?" Sherlock said, his voice so deep it must have brushed against the seafloor, as one of his eyebrows rose above the other suggestively.

John's breath caught in his throat and his heart fluttered in his chest.

John nodded his head ever so slightly.

The neighbors of Baker Street remembered that Halloween vividly.

After they witnessed Dracula grab Frankenstein and passionately snog the living hell out of him, the two monsters retreated upstairs, abandoning their candy bowl for the children to feast on.

Happy Halloween Sherlock.

Happy Halloween John. ;)
