   Summary

   Simon is not prepared to see Grace in the lab that morning. Not because he wasn’t expecting him to be there, but because he wasn’t expecting the man to be in a tank top and what appear to be booty shorts that say “I’m collecting data” over his ass. 
   The man is hunched over the table with his head hung low. Mark stands beside him, gently rubbing his lower back as his limbs tremble, occasionally skimming his fingers under the waistband of his shorts or the hem of his shirt. He’s holding something in his other hand.
   If Simon listens very carefully, he can hear something buzzing faintly.

   OR

   The one where Grace gets teased and ravaged by his lovers.
