Jack backed the Master to the rail, leaning against him, a wicked smile on his face as he wrapped one end of the tie around the wrist of the hand he still held, careful to tie it just snug enough to stay on, but not tighten too much. Holding the Master's gaze, he drew the hand behind the Master's back, wrapping the tie around the railing, leaving enough for him to secure the other wrist with the other end.
Leaning in, he pressed a lingering kiss against the Master's lips, his hands resting on the railing on either side of the Time Lord. He kept himself just far enough away that the only point of actual contact was their lips.
