John hasn't had a patient for over an hour when Sherlock texts him.

I want to play a game. -SH

John laughed as he read it and swiftly sent back a text.

I'm working. And you, play a game? You hate games. Need I remind you of the Cluedo incident? -JW

No, you're not. You're talking to me, and given that it's a bit faster than usual especially considering your terrible response time. Besides. It's a social experiment. The work comes first. -SH

And you said that you wouldn't bring that up again. - SH

What's the hypothesis? -JW

I desire to assess my body's physiological responses when presented with various written stimulus that could otherwise be deemed erotic. I've already read your stash of erotic novels and noted the results. Really John? Most men have magazines. Are you a 40 year old woman going through a rough divorce? -SH

Ignoring the jibe, John focused on the first part.

You want me to sext you? – JW

Simply put, yes. -SH

No. -JW

Why not? -SH

-SH The social implications of a man writing such things to another man, it..

Just a bit not good. -JW

Really John. Now is not the time to be delving into your homophobic tendencies. The work needs you. And the only people seeing this conversation at all are me, yourself and of course, the fat cake eater. -SH

John dropped his phone as he read that last message. Mycroft was tapped into his phone.

It pinged thrice.

Of course I have your phone tapped, Doctor Watson. Security measures, you understand. Don't worry, I'll have Anthea dispose of the history of this conversation when you two are finished playing 'Sherlock's game.' And any subsequent replays that may occur. -MH

By the way, you really should take more care of your things. Dropping your phone will damage it, as you well know. -MH

And if you don't, I'll just have to recreate my mould spore experiment on one of your jumpers. I think I'll use the cream one. It's particularly horrid. -SH

Alright. Fine. Just leave my jumpers be. Mycroft, can't you do something else? -JW.

Consider it done. – MH

Enjoy the cake. -SH

John? -SH

Yes? -JW

How does one go about sexting? -SH

Really, Sherlock? Why would you go into this without research? -JW

Unbiased experiment. I wanted to do it without any preconceived notions about what I should and should not do otherwise it is an unfair test. Also, this is more your area. You even have a ridiculous nickname. SH

Right. So the test is to assess your body's physiological responses when presented with erotic written stimulus, and the variable this time is your emotional attachment to the author. And because I am said author, I would be conducting this experiment. Yes? -JW

Right in one, John. -SH

I'm not even going to consider the implications of your assent to that statement. -JW

Would I be remiss in requesting we get to it? – SH

Not at all. -JW
