It's been a long night, and Usopp is tired. Very much so. He heads for bed, and since Chopper does so at the same time, he goes into his own room.
After spending a while sitting on the edge of the bed and counting under his breath, he opens the door and checks to see if the corridor's free. It is, so he quietly pads down the hall and into Franky's room. Franky greets him with a kiss on the forehead as he slides into the bed. Although they both huddle close together, neither closes their eyes. After all, they're waiting on a certain someone.
Eventually, the door creaks open and a pair of disembodied arms invade their cuddle, pushing just hard enough to create space enough for a third person, yet gently enough for the two men to remain together. Robin eases into the space she's created, gives each man a quick squeeze and settles down for the night, as usual.
But tonight, something's a bit different. Tonight, the door opens for a third time and a shadow appears in the doorway. The owner says, "Hey, guys." They all make noncommittal noises along the lines of, "What is it, Luffy?"
He nervously fiddles with his hat and asks, "Can I sleep with you tonight?"
OH MY SQUASH, IT'S IN THE FREAKIN' PRESENT TENSE. Oh, my poor braaaiin. (Dies.)
I didn't actually write this with intent to Merryship, but I guess you could take it that way if you really want to? Please don't pack a sad about Franky kissing Usopp on the forehead. I swear on my good name as a fanfic author that it has no sexual connotations whatsoeva. (At least, that wasn't my intention…)
