A/N: Dedicated to OG, Fae Fae and Sgt Wall, who I know love a bit of Mystrade. Enjoy, guys!

Mycroft Holmes was tired of constantly being in charge or everything, so 3 night a week (Monday, Wednesday and Friday), he graciously allowed his partner, Greg Lestrade, to take charge.

Nothing thrilled him more than letting the DI get out his handcuffs and force Mycroft to be submissive.

Of course, on the other days, part Sunday – neutral day – Mycroft was permitted to relieve Greg of his power and remind the DI who was really the higher power.

This theory worked well for the two of them, each able to spend their separate days wondering what their partner would do this time or what method to use themselves to make the other moan.

Of course Sherlock knew, but he did his best to ignore it and pretended his brother and semi-boss were not a couple, because he didn't think he could bear the thought.

A/N: Not very long, I know, it's only one page in my notebook. Still, leaves a fair bit to the imagination!
