On The Other End of the Line (слэш)

He has been strongly advised against picking up calls from blocked numbers. The fall of SHIELD has afforded him many enemies, and blocked numbers can’t be traced. But it’s 3 a.m., the phone is ringing, and Steve is dazed and somewhat spooked.
“Hello?” he mumbles groggily, his voice muffled by the pillow.
“Steve?”
Steve’s eyes snap open. “Bucky?”
Wherein: after the fall of SHIELD and the disappearance of the Winter Soldier, Steve receives an unexpected call from Bucky. It’s the first in a long series of calls that leave Steve longing for more – only, he doesn’t know Bucky’s number, whereabouts or current activities. All he can do is wait, on the other end of the line.
