first of all, wow i am very surprised to have gotten more feedback. secondly, thank you for the ask!
Firefighter!Bokuto is nothing short of a Truck Captain! For those who don't know, trucks are the larger fire apparatus that usually hold an arrayment of ladders, tools, and do shit-break shit type of stuff. Truckies are the rootin' tootin' ventilation, search, overhaul and much more folks. As a Truck Captain! Bokuto is going to be a senior himbo catching jahbs and breaking shit.
TruckieCaptain!Bokuto was assigned to the truck because he's the Mayday master. This man takes his job so seriously, and he's dedicated years to the art of rescuing down firefighters when a fire goes haywire. He's more than proficient at throwing weight around and tying knots in the dark, in the rain, and with his hands behind his back. He's a captain on the truck because he's even more skilled at making group decisions that keep his folks safe and alive.
TruckieCaptain!Bokuto is one of the few captains that can be a bit of a wildcard outside of the fire ground. He's constantly playing pranks, but it's a toss-up as to whether or not he'll appreciate pranks being played on him. If he's feeling sensitive, usually his fellow truckies will have to call you to cheer him up.
TruckieCaptain!Bokuto loves to teach people new things because he learns best by teaching others, and he won't stop sharing his knowledge until someone shuts him up. You usually have to shut him up with a kiss or he will ramble on forever.
TruckieCaptain!Bokuto would whole-heartedly ask you to stop by the station while he's training his rookies on rope rescue, and you being the sweet fire spouse you are, you'd listen. Little did you know, he has his rookies rig you up in a harness to be raised and lowered a few feet like a helpless victim. The way he gets protective and triple-checks the rigging and belay systems has your heart swooning. "You drop my spouse and two things will happen: you'll be on light duty, and I'll be on mandatory leave for 30 days. Do the math."
I mentioned earlier about TruckieCaptain!Bokuto knowing how to throw weight around. This translates to the bedroom very easily. Bokuto could come home from a long 72hrs of himbos running around throwing things, and he's in heat when he sees you resting peacefully in one of his PT shirts from his rookie days. next thing you know, you're being woken up to being folded in half, his throbbing cock teasing your hole until you're begging him to fill you up. "anything for you baby" he smiles weakly as he finally pushes in.
TruckieCaptain!Bokuto talks alot about his job, and it gets to the point where you have to keep a checks and balances system to make him leave work at work. As a half-joke you'd say "one remark about work equals one ruined orgasm" and he thinks it'd be fun to push his seldom dominant lover. One remark becomes three becomes five, and now you've got him sitting between your legs, back to your chest as you stroke his throbbing cock lazily, hand swiveling deliciously over his leaking tip as his hips stutter into your hand. your free hand his holding his jaw in place, forcing him to look into the mirror you placed in front of the two of you. He's pretty with his eyelashes speckled with tears, cheeks flushed as he pants desperately at your mercy. Just as he begins those sweet whines you know all to well, you remove your hands from him, and he cries out in the most defeated voice. "I told you not to misbehave, Captain. Now, you pay the price."
TruckieCaptain!Bokuto practices his knots on you more than you'd like to admit. It started out sweet, him just tying knots around your water bottles or jokingly tying you to a chair to practice his 3:1 mechanical advantage rigs. The thought of using them as handcuffs was something he didn't really think about until one of his firefighters mentioned doing it to their spouse. He's quick to think of how well he'd be able to convince you, and all it takes is a "baby please," before you're agreeing. It starts with the figure-eight-followthrough, and he decides that one is the easiest to maintain. His cock would throb inside you with each glance at the handmade restraints, seeing your pulling tighten them made him want to bust a load almost immediately. He then moves on to the clove hitch, liking how quick he could secure all of your limbs to your bedposts, his own personal star. The stretch of being held open made your slick pool, and for giggles you'd struggle at the restraints until he'd mockingly say "angel, you know better not to test a captain."
I hope this is just what you were looking for <3 ugh, i love truckies.
