Man I got angry at a person so ima write shit from there fandom they won't like. ( I'm in the fandom too hehe 😈)
Steve and Jim absolutely got to some nasty shit. Like it wasn't even a pass time thing it was need most of the time.
They were hungry for each other. Every single time the Harrington house was called on for whatever reason (upset old people) Jim would always be the one to answer the call and go the house. Just so he can make everyone leave the party and 'scold' Steve.
It really only started when Steve was threatened to get a call from his parents to stop the load noice and partying. So he begged to Jim to not do that so he doesn't get in trouble, almost crying with those beautiful, brown, lashed eyes.
Hopper agreed, but only if Steve did something for him so he won't have to threaten him so much.
Steve agreeing just for his sake but over time he ends up having fun with the idea of having sex with a cop and the age gap itself. Realizing that Steve may not be as straight as he thought, and figuring out his type FAST.
Jim has always been into the boy but never found a way to get close and after seeing the moment of opportunity he did not back down, does not regret it whatsoever.
Fucking in the living cough, kitchen island, pool chair, in the pool, bathroom tub and shower or just against the door. Even in the parents room, they did not quit.
Steve loving Jim's body, the hair, the tummy pudge everything. He had a nice sizable cock roughly 6 to 7 inches but that girth was like no other. Jim equally loving Steve's body, the nicely toned body, thats got a simple warmth color. Hairless, smooth, and oh so beautifully decorated with freckles and moles.
They can't get there hands of each other
Jim had to prep for a good solid hour with a shit tone of lube just to make sure Steve wasn't gonna get hurt. Even then he slowly paced himself in just in case. Steve wanting it quick and hard but Jim wanting to take his time in the first half until he get demolish that ass, and finding all the best angles to make Steve happy
Jim wanting try multiple things with him, fingering him so hard Steve male squirts, having Steve jerk him off with his feet. Even Jim shoving his dirty sweat filled underwear in Steve's mouth while he's tied to the bed frame, stomach facing the ceiling and legs in a makeshift spreader bar. Maybe even piss kink ehhhh? (◍•ᴗ•◍).
It only stopped once Will went missing and Hopper having to focus on work, and Steve also having to focus on school.
But they both never forgotten and do miss it but they moved on and are perfectly fine with it. Steve do miss that dick though and Jim misses that hole like it's a long lost friend.
