Hyunjin was typically pretty vanilla when it came to sex. He liked simple and slow love making-sometimes he didn’t mind if Changbin was a little rough though. They usually opted for missionary or cuddle fucking. Recently, Changbin started slapping Hyunjin’s ass playfully. At first, he thought nothing of it. But sometimes Changbin did it just a little too hard. It stung but Hyunjin…didn’t mind? Hyunjin isn’t necessarily that fond of pain, because who likes pain? But then he really started to notice how big his wife’s arms had gotten. He was constantly in the gym working out, he’d always compliment and appreciate them but…damn he was strong. And then, he found a porn video on his timeline with the bottom being pounded into while spanked, he finally broke.
The next time their kiss got a little more heated, Hyunjin started to get nervous. He wanted to ask and bring it up, but he was afraid Changbin would reject him or find him weird. He knew his wife hardly ever judged him, but it was still a fear. Changbin rolled on top of Hyunjin, kissing him softly and their tongues sliding against each other. His cock was hardening quickly as he grinded down on Hyunjin, pulling a whimper from his throat. The more they kissed, the more desperate they got. Changbin finally pulled away to kiss down his jaw and neck, sucking red marks into Hyunjin's pretty skin, turning him into his art project. He couldn’t help but whimper as he kissed him and ran his hands all over his body. He lifted his way-too-big shirt up to his neck and started kissing down his chest, stopping to kiss and suck each nipple. Changbin definitely loved taking his time and worshiping his wife, and Hyunjin loved it. By the time Changbin got to his tummy, he was extremely nervous.
“Umm…hyung…?” Hyunjin shyly whispered out at the older man. He instantly took his lips away and looked up at him with concern, making sure he was okay. All he gave was a small ‘hm?’ and a small head tilt to show he was paying attention. Hyunjin’s face went bright red at the sudden attention and for what he was gonna ask.
“Can we do something we usually never do…?” Hyunjin painfully fumbled out, looking anywhere but Changbin. When he looked back, Changbin was kissing his tummy a few more times with a big smile.
“Of course my love, what do you want to do?” Changbin questioned him, sitting up a bit between Hyunjin’s thighs. He rubbed his hands up his sides and rubbed circles into his belly.
“I want to do…doggy…” he said with a blush creeping up his face. They’ve only done it maybe two or three times in the early stages of their relationship, still figuring themselves out. Changbin seemed to perk up with a small smile on his face.
“Yeah? You sure baby?” He asked him gently. Hyunjin nodded at him slowly and Changbin’s smile grew.
“On your hands and knees, baby.” Changbin ordered him while backing away from his hips to give him room. Goosebumps erupted over his skin as he flipped over and hesitantly got into position. He could hear the nightstand drawer being opened, followed by a cap being opened. He fully let his arms give out, his cheek and chest pressed into the mattress with his ass high in the air. A small groan fell from Changbin’s lips as he groped his ass over his boxers. Dipping one finger under his waistband, he pulled them down and off. Hyunjin forgot how exposed he felt in this position, how shy he was about it.
“God baby…look at that pretty little hole.” Changbin moaned softly, pulling his cheeks apart and kneading the flesh. His cock was already hanging hard between his legs. Somehow every touch felt 10 times better in this position. He heard a slight squirt of a bottle and prepared himself for the cold. Changbin was nice enough to whisper a soft “gonna open you up,” so he wasn’t completely shocked.
It still made him clench a bit, feeling Changbin run his fingers up and down his hole. He whimpered as one fingerpushed into him. Soft moans left his mouth while being stretched, Changbin’s fingers working him slowly with soon-to-be 3 fingers. Changbin wasn’t the longest in length, but he was thick and Hyunjin had to be prepared. He scissored his fingers and pushed in as deep as he could. Hyunjin had to let out a loud whine for Changbin to finally fuck him properly. The weight on the bed shifted as he finally settled behind him, the tip of his cock resting right on his pink hole before squirting some more lube on his cock.
“Need you to relax, princess.” he said softly while slowly pushing himself inside of him. They both groaned at the same time. Why haven't they been using this position more? Changbin’s grip on his hips was tight as he pushed himself in slowly. Hyunjin trembled and whimpered loudly at the big intrusion. His shirt slid up his back, pooling at his shoulders and exposing his back. He could hear Changbin groan behind him before his hands were rubbing up and down his back. He gasped softly and relaxed into his touch, helping to alleviate the stretch. It wasn’t long before Changbin’s hips met Hyunjin’s ass. “You’re so fucking tight baby, fuck.” Changbin groaned, slowly pulling out and back in.
Hyunjin let out loud moans as Changbin picked up his pace, one hand on his back and one hand on his hip. This was such a switch up from what they usually did, the energy and tension seemed so much more charged. “Do you mind if I speed up baby? You feel so good.” Changbin groaned out trying to keep his current steady pace. Hyunjin moaned loudly at his question. It was so sexy that he asked to make sure Hyunjin was okay with it.
“Faster..Deeper.” Hyunjin moaned out, his cheek still pushed into the mattress. This was rare but Hyunjin felt addicted, intoxicated. Changbin gripped both of his hips and sped up, thrusting his hips even deeper into his wife’s hole. Hyunjin felt lost in the pleasure, completely forgetting for a moment about what he wanted to try. “Hyung…can you spank me…?” he cried out softly, gripping the sheets. Changbin’s rhythm slowed down a bit at his question. Hyunjin couldn’t see it but he had a huge smile on his face.
A bit of panic rose in Hyunjin as Changbin slowed and was quiet for a second. “I’m sorry if it’s weird…you don’t have-“ He couldn’t even finish his sentence, he felt a hand coming down to smack his ass. The moan that came out of his mouth was embarrassing, he could feel himself clench around Changbin’s cock.
“Mhhh like that baby?” Changbin purred out before resuming his pace. Hyunjin’s brain short circuited, he loved it.
“Fuck…yes. I…want more.” Hyunjin shyly admitted between moans. He heard Changbin chuckle before picking up his pace, quite literally pounding him into the mattress. The bed was squeaking slightly, combining with the groans from Changbin, whiny moans from Hyunjin, and the wet obscene sound of their skin slapping.
Changbin brought his hand back down to his ass, smacking him harder than before. “My pretty little slut, wanting to be spanked. Didn’t know my baby could be so naughty.” Changbin chuckled, smacking him again on his other cheek.
Hyunjin cried out on every smack, enjoying the sting and the pain that went straight to his cock. Changbin was so fucking strong and probably didn’t even realize it. He hit hard, and it felt so good to Hyunjin. The shame he felt when he first asked Changbin suddenly washed away when he realized Changbin was into it just as much as he was. He was never able to cum from just penetration but he could feel the familiar knot tightening in his tummy.
“Baby…I think I'm gonna cum.” Hyunjin gasped out.
Changbin removed both of his hands from Hyunjin’s hips, forcing him to bounce himself back on his cock by himself. With his orgasm rising up in him, he was filled with determination to cum like this.
“Just like that princess, so fucking sexy.” Changbin said before smacking his ass again. Hyunjin fully yelped out and dug his face into the mattress, trying to silence his disturbing amount of moans and sobs. His ass was turning red- an outline of Changbin’s hand could be made out on his warm glowing cheek. Hyunjin desperately rolled his hips up and down Changbin’s cock. With his face in the mattress, he could hardly breathe, and it made him feel lightheaded and fuzzy. He was taking small gasps of air in between moaning, and he didn’t want to come back up for air.
Changbin’s hands came back to his small waist, his grip even tighter than last time. This time, he was relentless with his thrusts- he fucked into him with no mercy. His loud moaning was a signal to Hyunjin that he was gonna cum soon, and he wanted to cum with him. He thought maybe he’d have to stroke himself to get there, but Changbin smacked his ass one more time, the hardest he had hit him all night. With the sting of the smack, and the lack of oxygen to his brain, he came, hard. He fully tensed up and his scream was muffled from the sheet. The way Hyunjin clenched around him from his own orgasm made Changbin cum inside of him. Fucking into him slowly after, pushing his cum in him as deep as he could go.
Changbin slowly pulled out while they both panted heavily. His cum was slowly dripping out of his hole, and all Changbin could do was stare down at it. “Binnn, a towel pleaseee.” Hyunjin whined. He loved the feeling of it dripping out of him but he didn’t want to completely soil the bedding. Binnie laughed before getting up to quickly grab a towel, slowly wiping his hole.
“Are you okay, love? That was pretty intense, and the first time we’ve done that.” Changbin said softly while rubbing Hyunjin’s red cheeks slowly.
Hyunjin relaxed on the bed. “I’m okay baby, that was perfect. Thank you for not judging me…” He said shyly before turning on his back to make grabby hands at his wife.
“I would never judge you baby, I loved it just as much as you did,” Changbin smiled warmly at Hyunjin before laying down in his embrace. His lips found their way to his lover’s and kissed him slowly. He never wanted to pull away, he wanted time to freeze so he could stay like this forever. Hyunjin’s kisses were so soft and tender he couldn’t help but feel butterflies in his stomach, even after the years they’ve been together.
“I’m so happy you felt comfortable and trusted me enough to ask, baby.”
Hyunjin smiled warmly at him before kissing him again. They stayed cuddled all night, Changbin rubbed Hyunjin’s sore skin softly until they fell asleep. They were safe in each other's arms, the outside world ceasing to exist.
