Mystrade fic

[grypas]

I'm looking for a story where BBC Mycroft and Lestrade have sexual encounters without much affection whenever Mycroft feels like it. Or at least that's how Lestrade interprets it. Mycroft doesn't cuddle or stay. That's why Lestrade feels that he has to end it. Mycroft seems cool and collected when Lestrade breaks up with him, but he really isn't.

ETA: found it! It's this one: At the beginning with you by alistair_wolfe
