Very excited this is being read and reviewed! Another couple of chapters up today. We're not finished yet

Greg dropped the cup of tea on the table next to Sherlock and returned to he sofa with his coffee. For a moment he wanted to pick another seat, to physically remove himself from his mistake, before he realised that the only other option was John's chair. Just sitting in the man's chair felt offensive after what Greg had put him through last night. So he dropped back down on the sofa, trying to ignore Sherlock's searching gaze, silently interrogating him over the rim of his teacup. They sat in silence for a few moments as they sipped their drinks and Greg slowly started to feel a bit more human. He'd head back to his flat, have a long shower and pretend last night had never happened.

"Why do you find John attractive?"

Greg winced. "I thought we weren't discussing this"

"We aren't discussing you trying to sleep with him. I'm just asking why you wanted to in the first place."

"Why do you care?"

"Humour me."

"Okay fine, I doubt you'll shut up till I do"

Sherlock smirked "Correct"

"Right" Greg sighed a steeled himself "He's strong, muscular, but with a bit of bulk round the middle, I like that, makes me feel less self conscious about my own." Greg rubbed his belly absent mindedly "He fair, with blue eyes, that's normally the type I go for, I don't know why. He's got a really dirty laugh, and a big smile, he's calm and brave and patient. Enough for you?"

Sherlock cocked his head "Interesting, you reference personality traits as well as physical attributes."

"Both of them have an impact on whether I find someone attractive."

"And all of them are the polar opposite of mine."

It was Greg's turn to cock his head "Huh?"

"Your list of attributes, fair hair, blue eyes, calm manner, bulky body. So you would say that I was unattractive?"

Greg gawped at Sherlock, at his full lips and his tousled hair, lithe taut body, those cheekbones...

"Sherlock you must recognise that you're an attractive man. I've seen poor unfortunates trying to catch your eye dozens of times."

"Yes, but not you, you find me unattractive, you just said so"

"Sherlock, you don't desire a checklist. Just because I happen to find blonde men attractive doesn't mean I can't be attracted to men with dark hair too."

"So you are attracted to me?"

Greg suddenly woke up to who he was having this conversation with.

"Where's this going Sherlock? Why do you care if I find you attractive? You don't find me attractive, you're not interested in sex. Do you just want this information in order to blackmail me into giving you more cases?"

"Who said I wasn't interested in sex?"

"I have never known you to go on a date, to even show the slightest interest in anybody. You've never even spoken about the subject. What's with all the interest now?"

"I want to sleep with you."

Greg choked on his coffee.

"Is the idea that offensive?"

Greg was about to laugh but he thought he could see what looked like genuine hurt behind Sherlock's imperious mask.

"No, that's not it at all. But we've known each other for years Sherlock, are you saying that you wanted me all this time? Because I find that hard to believe."

"Don't be so melodramatic. I'm just..." Sherlock paused, he seemed to be struggling to find the right words.

"I'm... intrigued. It's not that I'm incapable of finding people attractive, it's just that I don't normally act on those impulses. After you and John's reactions to what happened last night, it made me think. I want to know why it's so important to people."

"What?"

"Sex"

"You want to have sex with me so you can understand why I wanted to have sex with John, and why John reacted so badly to me wanting to have sex with him?"

"Yes"

"Well, that's romantic."

"Should I have bought you flowers?"

"Okay, romantic was the wrong word. I think what I'm saying is Sherlock that when I want to have sex with someone it's normally because I find them attractive, not because I want to conduct some sort of social experiment."

"I do find you attractive."

"Since when?"

"Since this morning."

"Yeah right, that makes total sense"

Sherlock sighed and stood up. Before Greg realised what was happening Sherlock had untied the belt of his robe, shrugged it off his shoulders and let in pool on the floor. Greg found himself staring at a pair of blue silk boxers pulled tight around what looked like an achingly hard erection.

"Greg" he never calls me Greg... "As you can see I am not unattracted to you, I won't mention it to anyone else, I'm not interested in blackmailing you, I've done this before, though it must be said with less than satisfactory results, so you're not "deflowering" me. Just..."

Sherlock was grasping for words again

"Show me. Show me why you wanted John, how you wanted John..."

Greg sat still for a long minute. This was clearly insane, having sex with Sherlock would be a very poor choice. Especially as part of a warped data gathering exercise that Greg was sure had much more to do with Sherlock's weird relationship with his flatmate than was healthy. But having that smooth, pale body in front of him, Sherlock asking to be taken, the mere thought was making his cock twitch and his mouth water. Greg made a decision. Fuck it. If he wasn't going to get any from the other resident of the flat he may as well take what was being offered, especially when it was so very very pretty...
