   Summary

   Atsumu points at their very naked selves. “Look. You’re an omega… an omega in heat… I think it’s pretty damn obvious what your body is telling you it needs.” 

   “I don’t follow.” 

   Atsumu looks at him, as if he can’t believe Kiyoomi is this dense. He sighs, long and deep. “Omi-kun. You need to get knotted. And I have a knot. Put the rest together.” 

   --

   Or, Atsumu (finally) helps Kiyoomi with his heat.
