PROMPT: Douglas forces Martin to cum in his pants right before a flight, timing it so he has to sit in it until they reach their destination hotel.
Eventually Douglas wipes him down and soaps him up in a nice hot bath (paying particular attention to making sure Martin's cock is spotlessly clean.)
Bonus for humilation kink and toppy Douglas keeping up a litany of chastising, filthy, degrading dirty-talk; focusing on Martin's lack of self-control, how slutty he is for being unable to wait and dirtying his clothes, and scolding him for getting hard in the bath even as he wanks him ruthlessly. link here

Fill can be found under the prompt as well as here on Ao3 and here on Tumblr.
