   Summary

   Suna actually likes caring for Atsumu when Sakusa and Osamu can’t for whatever reason, or when they’re just hanging without the two and Atsumu slips. When he’s throwing a tantrum and just won’t calm down no matter what they try to offer him, it’s usually Suna who’s called if both boyfriends and Aran are busy.

   Part of the reason he’s so good with the fussy baby is because he was the one to piece together that there are times Atsumu’s oral fixation can only be satiated with a cock to suckle on.

   Or; Suna is called to comfort and care for a miserable little Atsumu while Osamu is busy with work.
