   Summary

   Sonic has been taking a heat suppressant and secondary gender blocker to conceal his omega identity since he was 17 and it's worked well. The world, and even his friends, believe he's a beta.

   When his heat strikes early at the start of a mission and the suppressant fails to work, he turns to the one person he never expected to help him conceal his condition.

   Shadow.
