Sherlock Holmes favorite part of John Watson was the bit where his belly joined his hips. That little furry bit about three inches below his navel and three inches above his cock that got exposed if he yawned and stretched. John always thought Sherlock could have picked a better feature to fixate on. His shoulders, even with the mangled scarred bit, were quite spectacular in their broadness. He had received several compliments about his legs as well, which despite being short were solid and muscular. And when he was in basic training the overall size of his manhood had been commented on favorably. So he didn't quite understand Sherlock's fascination with that particular area of his body. But then Sherlock was never going to be normal. The first time he had become aware of Sherlock's fascination had been whilst he had been trying to reach the new box of teabags on top of the cupboard in the kitchen. Sherlock had licked him. Actually licked him, like an ice-cream.

John's favorite part of Sherlock was the nape of his neck. The nape of that very long elegant neck, where his dark curls herringboned down into the white skin of his back. John would happily spend hours stroking the soft milky skin until Sherlock fell asleep. Of course, Sherlock's overall gorgeousness registered pretty high up on the "totally shaggable" scale, but it was mostly the back of his neck that got John all hot and flustered just thinking about it. He was very jealous of Sherlock's scarf. As a keen student of anatomy back in the day, John supposed he should have been more interested in Sherlock's ridiculous cheekbones or his long legs. But he liked his neck. And that was that.

It was one late evening in Baker Street that found John tapping away on his Laptop whilst Sherlock slowly overdosed on nicotine patches on the sofa.

"John, I'm bored."

"It's your own fault. You should have taken that case Lestrade wanted help with."

"The British Museum and a missing dinosaur? Don't think so."

"I like dinosaurs."

"You used to collect fossils as a child."

"Yes. And how did you know that? I supposed you deduced it from my ammonite paperweight?"

"What that thing that looks like a stone turd? I asked your sister what to get you for Christmas. She said you used to like fossils."

"Oh. "

"I really don't think the Police need my help finding a skeleton that is 25 meters long."

There was silence. John stood up and stretched a little. Suddenly he had Sherlock's full attention, one eyebrow arched suggestively. John pulled his jumper down in a desperate act of self defense.

"Dinosaurs have very long necks, don't they John?" he pushed his silk dressing gown from his bare shoulders and leaned forwards a little.

"That's really not fair." But John had already pulled his jumper off over his head and was making his way up Sherlock's back towards his neck with eager lips when both mobile phones, the flat phone and John's laptop all signaled incoming calls and messages.

"I suppose it might be important." Sherlock grumbled as he answered. "Holmes. Good evening Inspector… What another one?... And how did no one notice this?... They brought the first one back?... How did no one notice that?... Anderson. Well that explains everything. We'll be right there." He looked at John for a few moments.

"The bad news, John, is that we have to postpone what I'm sure was going to be another evening of mind blowing sexual intercourse. The good news is you get to go to the museum and play with the dinosaur fossils."

"I'd much rather stay here and play with you. Anyway I thought you said a missing dinosaur wasn't interesting enough."

"That was before they brought back the first one they stole and then stole another one. I want to see how they did it. Come on John, this is interesting. I thought you liked fossils."

"When I was eight I liked fossils. I grew out of it."

"When I was eight I liked Mozart and the periodic table. You must have had such a simple carefree childhood. What was it like?"

"Shut up and give me back my jumper."

Sherlock was already dressed by the time john's head emerged from inside his sweater. His lovely neck was safely covered with his blue scarf where it would not cause any distractions.

"Come on John. The game's on again!"
