Third Person POV
Levi was used to Erwin wanting to experience kinks to see if they liked them or not. Their sex life used to be a little boring until Erwin decided to spice it up.
Levi's favorite was bondage. Though he'd never admit it. He loved being restrained while Erwin had his way with him.
Erwin's favorite was the thought of being caught. He'd fuck Levi in public places, or even while the kids are home.
Levi's heart was always racing during this, not wanting someone to see him being dicked down by the CEO of his company. It'd look bad on him, of course maybe not if his kids caught him but still.
Although, he does like how Erwin restrains his wrists. It distracts him from the fact they're in public. His thoughts drifted off to the times where Erwin would smack his ass, hard if he made any noise.
He shook the thought away when he reached the top of the stairs. He walked to he and Erwin's room and there Erwin was, texting someone on his phone. Levi peeked over his shoulder and read the messages.
Marie.
Levi frowned and furrowed his eyebrows when he saw that she had sent Erwin a big, purple heart.
He bit his lip to avoid yelling and quietly walked to the bathroom they shared. He stepped in the shower and turned on the water, cringing as it hit his skin.

When he got out he wrapped a towel around his waist. He walked outside and Erwin was now on the bed, dropping a book to fuck Levi with his eyes.
"Take a picture, it'll last longer." Levi said, opening the closet for a fresh pair of clothes.
He heard the bed springs behind him and then gasped as Erwin lifted him up. Now of course, Levi was strong. There was even a few occasions where he'd defeated Erwin in play fights.
But Erwin was still stronger than him. He felt the towel drop to the floor and grabbed onto the closet for support.
Erwin was holding him in a position where he had his ass in the air, fully open to Erwin. His cock sprang to life as Erwin licked a wet stripe on his ass.
Levi shuddered at the feeling. They'd never done this as frankly, it was disgusting. They hadn't ever talked about it but Levi thought it was a mutual feeling. He never let ANYONE'S mouth near his ass.
He was tempted to use the safe word when Erwin licked around the rim of his hole. He gasped and moved his hand to his mouth.
"Erwin....kids...kids a..re, ho...me.." Levi choked out as Erwin rimmed him, occasionally dipping his tongue inside.
Levi put the back of his hand over his mouth and let out a mix of pants and moans.
"Erwin...please.." Levi begged.
Erwin didn't talk. He couldn't talk with his face buried inbetween Levi's ass cheeks.
It was the position that turned Levi on the most. Being held like this and not being able to struggle, move or attempt any sort of escape turned him on. His cock twitched slightly, dripping pre-cum.
He bit down onto his hand to stop noises from coming out.
"I wanna hear you, Levi." Erwin said, removing his face from Levi's ass.
Levi shook his head, too embarrassed and scared his kids would hear him moaning like a teenage slut.
Erwin changed Levi's way of being held into bridal style and laid him on the bed. He hung Levi's lower body over the edge of the bed and kneeled til his face was met with Levi's ass.
