A/N: Bucky is tired and needy and just wants to cuddle. (who. fuckin’. wouldn’t?!)
If there was ever something more adorable than Bucky being tired or in any way not feeling well, you’d never seen it. Now, the serum made sure he was never not feeling well, but it didn’t help exhaustion after a week long mission with only 2 hours of sleep a day.
This is why he came stumbling into your floor, somehow overriding every security protocol with his left over spy-skills, calling out your name at two in the morning.
