You can't convince me that Barry wouldn't be waiting for Bruce on his bed, in Batman booty shorts, a Batman crop top, and a black collar after he knows that Bruce has had a long, tiring day. Bruce would just walk in, see him, and smile. Either out of appreciation, love, lust, or just happiness that his lover is there. He just walks over after shutting and locking the door, wraps his arms securely around Barry and gives him a kiss and holds him for a bit, and they either do some stuff or he gets Barry out of the collar and they cuddle.
