Kitten?

Summary:

After Kelly and Matt talked about their list of kinks or things they want to try in the bedroom, they explored the first on the list.

🔥🔥🔥

Matt and Kelly are on shift, and Kelly keeps sending Matt these smirks and grins, and Matt doesn't know what to do with them.

They aren't a secret to 51 but the rest of CFD. They have the needed paperwork that allows them to work in the same house on the same shift, but if it isn't necessary to come out to the entire CFD, then they won't—no need for unnecessary drama.

But right now, they are eating. Kelly is sitting at the round table with squad, Matt is sitting at the long table with truck, and Kelly keeps smirking over at him. Matt thinks that this has something to do with the list of kinks they've made. That was a week ago, neither has acted on the kinks yet, and Matt is a bit scared for some of them from the list. He trusts Kelly, and he knows that he would never do anything that would hurt him, but there is still a bit of fear mixed in with the excitement.

"Hey Casey, what's with Severide?" Hermann asked, putting down his plate of food and sitting beside Matt.

"I have absolutely no idea," Matt says, and Hermann narrows his eyes at him but doesn't say anything.

This has been going for the entire shift, and Matt had asked Kelly about it, but of course, he acted all innocent. What startled him more was when Matt was walking past the squad table. Kelly pulled him onto his lap when all of the squad was sitting there. Matt looked like a deer caught in headlights and turned to Kelly, who was laughing, and then he kissed him on the lips and let him get off. To say Matt was confused would be an understatement.

Finally, the end of shift rolled around, and Matt was getting changed when Kelly wandered over and sat on the bench looking all innocent.

"You two coming to Molly's tonight?" Hermann asked.

"Maybe," Kelly answered before Matt got the chance. Matt looked over, confused, and Kelly shrugged. "Ready?"

"Yeah..." Matt said, putting on his jacket, and Kelly jumped up and took Matt's bag.

"Let's go," Kelly said. "Bye," he yelled to everyone else and took Matt's hand with the other and pulled him out of the locker rooms.

"Okay, seriously, what's going on?" Matt asked, interlacing their fingers.

"What do you mean?" Kelly asked, and Matt rolled his eyes.

"Come on, Kels. What's up with you?" Matt begged, and Kelly laughed and shook his head. Matt huffed and gave up, and Kelly only laughed more.

The drive home was Matt staring at Kelly and trying to get anything out of him. Kelly did nothing but smile and drive and ignore Matt's intense eyes.

Finally, they got to the loft, and Matt about gave up trying to figure out what Kelly was up to. He took off his jacket, put it on the coat hanger, and started making his way to their bedroom.

"Wanna know why I've been acting the way I have?" Kelly whispered in his ear. He wrapped his arms around Matt, one arm around his waist and the other slowly moving closer to Matt's crotch. Matt tensed up, but his heart started beating rapidly. "Huh?" Kelly whispered again and grazed his hand over Matt's growing bulge. Matt lets out a shaky breath and leans into Kelly.

"Y-yeah," Matt lets out shakily as Kelly starts to palm him slowly. He drops his head on Kelly's shoulder as he starts leaving feather-light kisses on his neck. Kelly only hums and presses harder against Matt's hard cock and starts sucking on his neck. Matt lets out a breathy moan and lets Kelly do what he does.

"I thought," Kelly whispered before taking his earlobe in his mouth and starting to suck. Matt moaned and leaned further into him. "We could," he whispered before taking the earlobe in between his teeth and pulling. "Do something," Kelly said before moving to the other side and taking the other earlobe in his mouth and started sucking. "Off the list," Kelly said before taking the earlobe in between his teeth and pulling on it.

Matt only moaned louder and bucked up into Kelly's palm. Then Kelly stepped away and walked in front of Matt, frowning at Kelly.

"Why did you stop?" Matt asked, and Kelly smirked.

"Follow me," Kelly said, turned around, and walked towards their bedroom. Matt looked down at his erection, begging to come out and then huffed and followed Kelly.

"Sit," Kelly commanded and pointed to the bed. Matt stared at Kelly before slowly walking over and climbing to the middle of the bed. Kelly grabbed a bandana and put it over Matt's eyes. "I need to get everything, so be patient, my love," Kelly said once he secured the bandana around his head and kissed his cheek.

Matt sat there, turning his head in the direction of the noise as if that would help him find out what Kelly was up to. He can hear Kelly shuffling and moving things around, but he can't figure out what he is doing.

"Ready?" Kelly asked and chuckled when Matt nodded eagerly. Kelly slowly removed the bandana, and Matt blinked a bit before looking down in front of him, and a blush crept up his face. A clear, almost crystal-looking butt plug was on the bed with a white tail and a black tip on the end. There are also matching white cat ears with black tips on a headband, a white laced collar and panties with black accents.

"This was off of my list," Matt said, not looking up from the butt plug.

"Yup," Kelly said, eyeing Matt closely. "Want to put it on?" Matt nodded and bit his lip. He reached forward for the cat ears, and they were nice and soft, and the headband was also white.

"Strip," Kelly commanded, and Matt got off the bed. Kelly laughed as Matt quickly stripped out of his clothes. "Eager are we?"

"Shut up," Matt said, hitting him with his jeans, and Kelly laughed more.

"Let's open you up," Kelly said and picked up the bottle of lube and the butt plug. Matt went to lay down on the bed and spread his legs wide. Kelly ran a hand up and down Matt's inner thigh before lubing up three fingers. He quickly opened Matt up before lubing up the butt plug and slowly pushing in.

"Good?" Kelly asked when it was all the way in, and Matt wiggled his butt a bit and nodded. He got off the bed and walked around the room.

"I like the tail," Matt said, and Kelly chuckled. Matt went back to the bed and picked up the panties, and saw a hole in the back for the tail. Before putting it on, he chuckled to himself but stopped and looked at Kelly before putting it on. Kelly looked at him expectantly, and Matt grinned, grabbed Kelly's shoulder, and pushed him out of the room.

"Hey, what's this for?" Kelly asked and turned around just as Matt closed the door in his face. "Hey, now that's just rude," Kelly said and heard a laugh from the other side.

"Surprise," Matt yelled, and Kelly rolled his eyes and walked to the couch and sat down. He was getting aroused, especially after seeing Matt fully naked and with a tail out of his ass. He didn't know he had this kink, but he was glad Matt wanted to try this either way. He was tempted to buy a tag and even more when he found one with the name 'Snowflake' on it. If he did buy it, he probably would've earned himself a smack upside the head.

"Ready?" Matt called out, bringing Kelly out of his thoughts.

"Yup," Kelly said, and the door to their bedroom opened slowly. Then Matt came out with the white kitten ears sticking out from his fluffy blonde hair with the collar around his neck and the white panties trapping his cock. Kelly's jaw dropped, and Matt looked at him with his wide blue eyes looking innocent as ever.

"Come here, kitten," Kelly said, and Matt walked over and stood in front of Kelly. He did a twirl around before climbing onto Kelly's lap.

"Do you like it?" Matt asked a bit nervously about Kelly's thoughts.

"I love it," Kelly said, looking Matt up and down. "Shit," he breathed out and looked Matt in the eyes. "Would you kill me if I get you a name tag that says Snowflake on it?" Kelly asked, and Matt rolled his eyes and sure enough smacked him upside the head. Kelly laughed and put his arms up in surrender.

"Well, I'm off to do some cooking," Matt said and kissed Kelly's lips.

"We are having a movie night after your done," Kelly said as Matt was getting up. Matt walked to the kitchen with more sway to his hips than needed.

Matt was cooking them a late breakfast, and he was swaying his hips not to tease Kelly but because he liked the feel of the tail brushing his legs. Kelly's eyes were glued to Matt's ass. He had only seen Matt in panties once, and he is still not used to how hard it makes him. It didn't help when Matt was swaying his hips and whistling in the kitchen.

"Done," Matt said, coming over, setting the plates on the coffee table, and sitting next to Kelly and moaning.

"Prostate?" Kelly asked, and Matt nodded, took a deep breath, and adjusted his position or tried to. The butt plug is pressing into his prostate no matter how he sits down. He huffs and sits curled up to Kelly's side. He doesn't know if it's because he is a kitten or he is basically naked and always wants to be near Kelly.

"Comfy?" Kelly asked, putting an arm around his shoulders. He put a blanket over both their laps and then grabbed their plates and put it on the blanket. Kelly turns on the TV, and they get comfy as they eat and watch.

After eating, Matt curls further into Kelly and closes his eyes. He is half asleep when Kelly starts running his hand through his hair, and sleepily Matt purrs into the touch. Kelly chuckles and kisses his forehead and lets Matt fall asleep.

After two hours, Matt wakes up, and he is no longer cuddled up to Kelly. He looks around and realizes that he is on their bed, hugging a pillow. He turns around and sits up only to moan as the butt plug presses further in. He gets up and walks out of the room to see Kelly sitting on the couch watching TV.

"Afternoon, kitten," Kelly says, and Matt walks over and climbs into Kelly's lap. Matt wrapped his arms around Kelly's neck.

Matt looked at Kelly with something in his eyes before rolling his hips down. Kelly groans and Matt takes Kelly's lips with his own. Kelly immediately wraps one arm around Matt's neck and the other around his waist. Kelly takes over the kiss and pushes the butt plug in more, making Matt gasp, and Kelly pushes his tongue inside Matt's mouth. Matt moans and puts up a fight with Kelly's tongue, but he was losing when Kelly lightly pulled the plug out before pushing it back in.

"Kels," Matt moans out desperately and rolls his hips down again, meeting Kelly's hard cock again.

Kelly moved his mouth down right above the collar and sucked a hickey as he continued to play with the plug.

"Fuck me," Matt breathed out and gasped when Kelly pushed in incredibly hard. Kelly stood and placed Matt on the couch.

"Turn around," Kelly said, voice lower than usual, and Matt scrambled to turn around on the couch. Kelly spread his thighs, making his ass on full display, and Matt leaned against the back of the sofa.

Kelly continued to play with the plug and listened to Matt's beautiful moans and gasps falling from his mouth. Kelly quickly stripped out of his clothes and ran to the bedroom to grab the lube. He came back to Matt with his panties off, but the tail was still there.

"Should I fuck you with it still in?" Kelly asked, mostly joking, but Matt looked over, and Kelly barely saw any blue left in his eyes.

"God yes," Matt moaned out. Kelly's jaw dropped.

"Kinky kitten," Kelly said more to himself, but Matt whined and wiggled his ass, making the tail sway. "Okay, okay, eager kitten," Kelly said and lubed up three fingers.

"I'm already opened," Matt said, and Kelly shook his head.

"You are for my cock, not my cock and the plug," Kelly said and pressed one finger into Matt, and Matt fell forward, gripped onto the edge of the couch as tight as possible. Kelly worked another finger in and rubbed Matt's back soothingly. Despite how hard he is, he doesn't want to hurt Matt, and he wants to do this right. Kelly worked up to three fingers, and Matt was now letting out nonsensical words as he was being overfilled.

"Ready," Matt managed to say, and Kelly nodded. He pulls out and lubes himself up, moves the tail off to the side, and lines his cock up with Matt's hole.

"Ready?" Kelly asked, and Matt nodded. Kelly pushed in slowly, and Matt's jaw fell, but nothing came out. He felt that everything was knocked out of his lungs, and all energy left his body. On the other hand, Kelly is trying his best not to go too fast because he wants nothing more than to fuck straight into him. With the plug, Matt is tighter, and the plug is pressing against his dick in the right way making everything more intense.

"Oh God," Matt said, letting his head drop and take deep breaths when Kelly bottomed out.

"You okay?" Kelly asked, and Matt nodded.

"Move," Matt said, and Kelly pulled out halfway before pushing back in slowly. He did a couple more experimental thrusts making sure the plug didn't fall out. Kelly pulled out before pushing back in slowly again when it didn't. Both moaned out, and Matt reached back for Kelly's hand. Kelly grabs it and interlaces their fingers before placing it on the edge of the couch.

"Faster," Matt said, and Kelly started to increase his pace. Kelly's cock is pressing into his prostate every thrust. Kelly wraps the tail around Matt's leg and lets it sit there as he thrust in and out, and the tail tickles Matt's cock adding to the experience.

"Ahhh," Matt cries out and pushes against Kelly meeting his thrust. Kelly moved faster and harder, and Kelly was staring at the cat ears and used that to drive him more quickly. "KELLY," Matt moans out, and he comes onto the couch and clenches hard around the plug and Kelly's cock. Kelly comes into Matt, and he leans forward and bites down on Matt's shoulder.

Kelly relaxes against Matt, and Matt is limp underneath him. Kelly pushes up and slowly pulls out, making Matt wince.

"Plug out?" Kelly asked, and Matt weakly nodded. Kelly pulls out the plug, and Matt winces again, and Kelly kisses the bottom of Matt's spine. Matt slumps onto the couch and cringes at the wet patch of his cum. He doesn't move his legs because he can't move. Matt looks over at Kelly, blinking at him with tired blue eyes. He makes grabby hands at him, and Kelly chuckles but moves to cuddle him despite the small space on the couch.

"That was a lot," Matt says, drawing random shapes on Kelly's stomach.

"A good a lot or bad a lot?" Kelly asked.

"Good a lot," Matt says and turns his head and places a kiss on Kelly's chest.

"Your ears stayed on," Kelly said and scratched behind the ears, and Matt lets out an involuntary purr. "I knew you have an inner cat."

"Shut up," Matt says and playfully slaps his chest.

"Bath?" Kelly asked with a bit of a laugh.

"Bath then another nap. Is it possible to fuck someone unconscious?" Matt asked, and Kelly laughed and shrugged.

"I did fuck you until you went into subspace last week," Kelly says as he holds Matt bridal style.

"True," Matt says and snuggles into Kelly.

"I like you as a kitten. You are more cuddly," Kelly says and only gets nosed at his jaw. Kelly smiled fondly and placed Matt in the tub as he got the water started.
