Omegaverse Bath House/ Sauna
Yuuji was feeling his rut coming. Even though he knew it was supposed to come every other month or so, he was always surprised by it and never took any of the precautions he promised himself he would take. Like asking for a partner beforehand. Or buying a sex toy. Or even, who knows, get a girlfriend. A tall girl with a big butt would be amazing right now.
He... Could ask his friends. Sure. They would help him.
But he... Lowkey, if he was being very sincere... He kinda ... It's a secret. But... He wanted to find his true mate.
Yeah yeah, every one always made fun of him for thinking about fated pairs. It's silly. His friends, specially Nobara, thought that sex was supposed to be easy and casual. He respected her a lot for this.
But
Like...
He couldn't help himself.
It's romantic.
He would like to enjoy fucking a tight pussy. And feeling his omega clench on him every time he whispers her name in a lazy summer afternoon. Ya know? And after he depletes her, he's going to grab a washcloth with warm water and clean her, worshipping her body and covering her with kisses and his own scent.
But alas. He was getting really horny.
His rut usually came from behind his belly button. He like... Felt an urge. To fuck, yeah. And to breed. But like... It was different than other times he was horny. It was hard to explain. But a rut was like being pulled down by his own body.
The solution now was to wait it out and fap his dick raw.
Or give this a try.
In his hands a pamphlet saying
OPEN SAUNA FOR RUT AND HEAT! FREE CONDOMS AND CONSENT!!
PAY AND ENTRY FEE AND FEEL FREE!!!
Sounded like a scam. But who knows?
Yuuji felt his feet taking him there. Why not?
What he could lose there? Nothing.
And what he could win? Maybe find his mate.
Looking up he saw he was already there. He paid the fee. Went to a locker room where you could actually lock his things. And went naked to an open hall.
There he saw a few pools of cold and hot water, a place for people to wash themselves before going inside the pools. On the back side, some open baths. A few vending machines with condoms and lube. Free of charge? Cool. Free water and energy drinks as well. Some towels.
Many seats between things. People washing each other backs and having a casual time. Happy faces. Very comfortable. Made him smile. He could see some of those were mated couples. And the ones that weren't... Didn't made his fangs ache. It's ok. He knew it was silly...
On the left side, an indication for a bathroom and a heavy wooden door.
Yuuji saw people coming and going and the heavy fog every time the door opened.
The sauna? Maybe?
He went there and yup. Yeah.
Yeah yeah yeah he came to the right place.
The sauna was bigger than his home. Like. It was twice the size of the classroom of his high school years. It was covered all around with hard wood, with steps for people to sit and, in the middle, a huge bed. Full of people. Kissing. And fucking.
His rut flared immediately. His heavy pine and orange scent, with a hint of sweet flowers, but not too much, got intense.
He lost himself in the sensation of touches. Kisses and he grabbed a tit here and there. And he felt hands on his biceps and abs. But his dick wasn't getting any action. He was aroused, yes. But not hard-HARD. He could fuck.
But he wanted that dream pussy that made him shiver every wet dream he had since he was 12.
And then he felt it.
The whole room trembled.
Nay.
Yuuji could hear moans and the sound of skin, no. Not skin. Bodies dropping.
The door of the sauna opened with a bang, the cold air seeping in like a reaper. And, with it, the smell of sandalwood.
Like a wave, starting from that man, people took breaths and moaned loudly. Every single person shook and came. And fainted. Like the best orgasm they ever had. Coming untouched from the scent of that omega.
And what an omega.
He was tall, taller than Yuuji, built like a truck made of muscles. But with a teeny tiny waist that Yuuji thought he could fit inside his hands, like a belt.
The man used his hands to take his hair out of his face, sharp eyes and holy fuck that bicep was bigger than his face?
The muscle fibers of his shoulders moved under his skin when he closed the door.
The raw power of those tree truck legs and diamond calves flared up when he got onto the bed with a step.
And Yuuji could see a faint scar by the man's lip when he looked down to him. The big shelves of pectoral muscles almost covering his face, with pretty pink nipples pointing down.
Yuuji was kneeling and salivating. He wanted to lick the mounds and valleys of those cobblestone abs.
“So, you're my mate eh?”
“Eh?”
The deep voice of that man made Yuuji startle a bit. This wasn't a dream?
“Yeah. My scent only flares during my heat. And then I use it to put down useless flies. The one standing up is the winner." He looked at Yuuji from up to down. Focusing on the angry-red erection he had going on. "And it seems I finally got a jackpot in this stupid gamble.”
The heavy dick directly in front of his face was chubbing up. And it was gorgeous. Perfectly shaped. The glan like a heart that Yuuji wanted to kiss.
But beyond that he could see the slick.
The heavily scented slick, dripping down the legs of that man.
His teeth ACHED. He wanted to BITE to CLAIM. To fuck that omega and breed him with pups and to make him scream in pleasure.
“Eh... Sir?" His voice cracked. Speaking required air and he kinda lost every speckle of it. "Can... I?”
The man got comfortable, using a bigger woman as a pillow, and opened his legs. The bodies around them fading into the background.
“Come to me pup. Might as well be yours.”
Yuuji lost consciousness right there.
Not exactly that. He was conscious. But he lost his breaks. Nothing was stopping him.
He got there and licked. From the source he could smell the heavy sandalwood, like a temple's incense, but a subtle hint of flowers. A delicate one he couldn't place. And he licked. And got those heavy legs over his shoulders. And licked more. Tasty. Rimming that delicious hole. So pretty, so perfect.
The man came with a low grunt. So hot. So... Contained. Mature. Yuuji couldn't take his eyes off. Looking everywhere.
Chiseled jawline. Long legs. Pretty fingernails. A huge-ass vein bulging in his navel. An unblemished skin, so supple.
He licked everything. What a masterpiece. Genetics and hardwork. He could tell.
Yuuji grabbed the waist. He couldn't fit everything, but by the side of the abs were some deep dimples that fit his thumbs perfectly.
With a huge ass smile he looked up to those storm-green eyes.
And the satisfied grin.
“Can I? Sir.”
Yuuji knew who the omega was. And who the alpha was. Be he also knew who was in charge.
“Go ahead.”
He aligned himself and in a smooth motion, slipping on that sweet slick, he got inside his mate. Balls deep.
It was so hot. So tight. Yuuji’s hips were moving and fucking in a steady pace. Searching for reactions. Up a bit. Down a bit. Until he fucked HARD. And the man left out the breath of a moan.
Oh
He liked hard.
So Yuuji complied.
“Can you get on all fours, mister?”
“Heeeh? Just because you asked nicely."
Yuuji couldn't deal with that voice. Like a lazy panther. Unbothered. Almost bored.
He wanted to wreck that men.
He got behind him and started fucking with all his strength. And he was strong. He was really strong. He never actually let himself loose before. Knowing people would get hurt by it.
But he got down, hugging that giant chest and pinching and grabbing and hurting those nipples like they committed a sin.
Fucking so hard he could feel his abs starting to burn.
And he could hear the small contained moans. Low enough that no one could hear, unless they were very very close to the source. Special.
The man was taking everything he had and was ENJOYING IT.
Yuuji almost cried.
Almost.
And then the release. The man’s scent spiked and he got SO TIGHT.
And Yuuji finally realized what that feeling he had on his rut was.
When the man came he took the bite. It was his mate and he was not losing him. He bit that beautiful beautiful nape. And he felt his knot expanding. It was the best orgasm he ever felt. The knot pressure was pumping even more cum that he usually released (and it was usually a lot. He had heavy balls after all) and the pleasure was making him see stars.
They were breathing hard and Yuuji wanted a kiss so bad, but he was stuck for a few minutes there. So he got comfortable, getting sideways and hugging his mate.
Well, not his mate yet. The omega gotta bite back for it to stick. He didn't know what kind of primitive world would allow otherwise.
But Yuuji was somehow confident.
“Mister?” - he whispered, the heavy heat of the sauna making the sweat in their skins feel natural, and the heavy smell of sex was not only their fault. But Yuuji was feeling almost high with their personal scents mixing.
“Hm?”
“What's your name?”
“Toji.”
“Toji-san, would you bite me back? I promise I”
Toji interrupted.
“Sure.”
Inside his head he was dancing and screaming in happiness. But he only hugged his mate with a strong hug. Scenting him. His dick twitching and the pleasure flaring again.
“Toji-san, aren't you going to ask for my name?”
“Nah. I know who you are.”
“You do?” The knot was subsiding a bit and with the help of his fingers he got out.
Toji changed positions and put Yuuji sitting in his lap. The position perfect for Toji to bite the side of Yuuji's neck. Unorthodox, but sexy.
“Yeah. You're my son's best friend.” - and he took a bite. Marking the boy as his mate, forever.
