Sherlock couldn't grow facial hair, whereas John could fairly well. Actually, Sherlock hardly had any body hair, especially since he shaved everything to be able to put his iPod somewhere.
Sherlock would always laugh when John wouldn't shave for a few days and sandy blonde stubble would appear on his face. When that would happen, Sherlock would almost beg John to shave.
"Let's do this again." John closed his eyes and smiled, "Good morning, my love."
Sherlock sighed an annoyed sigh, "Good morning, John."
John coughed a coughed, like he was trying to get Sherlock's attention.
"No." Sherlock said.
"Come on, Sherlock. Kiss me."
"No."
"Why?"
"You need to shave."
"I need to shave?"
"Yes, your face has those annoying little prickly things and I don't like it."
"I always thought facial hair on a man was sexy. You can't grow facial hair-"
"Is that a flaw?"
"No, no. That's not what I meant."
"Well, I'm not kissing you until you shave."
"Suit yourself. I can wait."
John didn't shave for another week after that. Honestly, John was getting a little lazy. He had saved up all of his vacation days to use them for a big vacation, a two and a half week vacation to be exact. John wasn't going to shave, cut his hair, or leave the apartment at all.
And Sherlock thought he was getting to look ridiculous. His hair was long, his face was just hairy, and altogether Sherlock thought he looked like a bum.
"Please, John."
"Please what?"
Sherlock had began this at a really random time. They were on a scene, actually. John just said something wonderfully brilliant and Sherlock had the urge to kiss him right there in front of everybody. But he held back. He didn't like when his face itched because of John's annoying face stubbles.
"Please shave."
"Wh-" John looked around at Lestrade, Sally, Anderson, and the new guy Jeff looking at him. "Now? Really? This can wait."
"No, no! How else am I supposed to reward you for being brilliant!"
John rubbed his eyes and mumbled into his palm, "You could wait until we get home."
"John, I have to agree. As someone that looks at you fairly often, it's time to take a razor to your face." Sally said.
"What's my face to you?"
"As a woman-"
"I'm not interested in pleasing women!"
"Obviously." Lestrade whispered.
"So, wait, they're-" Jeff began to ask about the relationship status between John and Sherlock, but was so rudely cut off.
"I am not shaving my face!"
"You look ridiculous, John! You look like a little hobbit man!" Sherlock said. Lestrade and Anderson chuckled.
"No, no. I am not-"
Nobody heard, but Jeff whispered to himself that facial hair is sexy.
"For me, John?"
"I do everything else to please you, this is my face, my facial hair."
"Yes, but we have to look at it." Sally said.
"If I was going to take anyone's opinion, it'd be his," John pointed at Sherlock, kind of disgustedly.
"Why won't you just shave it?" Lestrade asked.
"Because for the past two weeks, we have had almost zero contact," John spoke, Jeff stared, "We haven't kissed. We haven't…well, that's none of your business. I'm not shaving because I want to win, just once. I am not shaving until I get kissed."
That was actually Jeff's cue. Jeff didn't really know what was happening, himself. All he knew was the silence between the members of the small group had gone on too long. Jeff took a step at John, took his prickly little hobbit face in his hands, and pressed his too chapped lips to John's.
The kiss went on as long as it took Sherlock to uncomfortably cough and regain John's attention. John stumbled backward, looking Jeff in the face. Jeff looked scared. They both looked at Sherlock quickly, who looked shocked and sort of angry.
Sherlock turned around and walked away.
"Sherlock, the case?"
"Check under each tire of the car. You'll figure it out. John, let's go."
John stood still and looked at Jeff. "Well, I-"
"John!"
"Right. Goodbye."
When they got home, John went straight to the bathroom to shave. By the time he finished, Sherlock was standing in the doorway wearing his special blue underwear and nothing else.
"Was it good?"
"What?"
"Jeff's kiss."
"Of course not."
"Why?"
"Because I don't like being kissed by anyone else. Just you."
"Then why are you shaving?"
John turned around to look at Sherlock and leaned back against the sink, "I don't like when it's not you."
Sherlock darted at John. He took John's smooth face in his hands and stroked as he kissed.
