Title: Closer than a Heartbeat
Characters/Pairings: Keith/Lance/Shiro
Summary: Shiro goes into heat. Keith and Lance assist him with that.
Notes: Written for Heat Wave: An ABO Voltron Zine last year. Omegaverse, obviously, explicit for smut, not canon compliant, 3600 words.
( Lance notices that Shiro is going into heat first, though it's not until after the dust starts to settle and they manage to compare notes that they figure this out. )
