_________________________________________

It had seemed like forever since Red Riot and Great Explosion Murder God Dynamight -(long ass name)- have seen each other for longer than a few seconds a day thanks to their jobs as heroes.

Tonight was their first night of having a full night alone together in what felt like years but was probably only about a month.

"Hey, baby~ what do you want to do now that we have all night to do whatever and not be worried about getting called in for the job?" Kirishima asked sweetly as he pulled Bakugo into a hug, the latter wrapping his arms back around Kiri.

"Let's fuck, I haven't had a good fuck in so long. Please can we fuck?" Bakugo stated before asking while giving Kirishima pleading eyes.

"I'm down for whatever baby, how far do you want to go?" Kirishima asked as he moved Bakugo so he was straddling him.

"All the way. Let's go all night too." Bakugo said as he began to roll his hips forward some, trying to create friction between the two.

"All night? Are you sure about that? Do you think you could handle all of that?" Kirishima asked before leaning down and kissing Bakugo's neck and jaw.

"Yes, I'm sure shitty ha-" Bakugo cut himself off with a moan Kirishima found one of his weak spots.

Kirishima smirked against the skin before sucking at it, and then gently biting it getting a louder moan from the horny blond.

Kirishima pulled away from the spot for a second before licking up the little bit of blood. He then kissed the spot as a small apology before moving up and kissing Bakugo's lips.

The kiss was quickly returned and deepened, it was filled with nothing but love and lust.

Kirishima flipped them both over so Bakugo was lying underneath him and he was imbetween the blond's legs.

He pulled out of the kiss and quickly discarded both of their clothes seeing as they were getting in their way.

"Do you want to start out more aggressive or slow?" Kirishima asked once he looked back down at Bakugo.

"Be gentle but start with the more aggressive stuff so once I'm overstimulated I won't be in a ton of pain," Bakugo answered getting a nod back from his lover.

"Do you want me to wear a condom?" Kirishima asked as he reached over to their bedside table and pulled out lube and a condom even though he already knew the answer. Bakugo had a thing for being filled up by his cum, it was kind of weird but he wasn't about to deny him of something so simple.

"No, don't worry about it. We will really need to shower though." Bakugo replied getting a nod from the redhead.

"I'm going to prep you now okay?" Kirishima said while lubing up his fingers.

"Okay just hurry up," Bakugo said getting visibly impatient.

He was always one that was super needy for more and more and more when it came to sex and was always super impatient as well. He wanted everything done as quickly as possible so he could feel the most pleasure.

"Of course love," Kirishima said as he put his middle finger into Bakugo's twitching hole.

The boy squirmed at the feeling. It had been so long since they fucked that this felt like the first time all over again.

"F-fuck" Bakugo stuttered out when Kirishima added another finger.

Kiri smiled and kissed Bakugo as he scissored his fingers that were knuckel deep inside of his lover.

Bakugo moaned into the kiss as the pain began to slowly go away and be replaced with pleasure.

Kirishima smirked internally when he heard Bakugou moan and decided to add the last finger inside of his tight hole.

"Ah, shit!" Bakugo whimpered out from the sudden pain.

"I know baby, relax as much as you can okay? You're doing so well." Kirishima praised having the older boy nod and relax as much as he could.

Kirishima slowly began to move the fingers in and out while distracting Bakugo with his other hand and mouth playing with his sensitive nipples.

"Aah~" Bakugo moaned when Kirishima began to scissor all three of his fingers, sucking on one of his nipples as his other hand played with the other.

"Do you think you're stretched enough for me now baby?" Kirishima asked instantly getting a nod from the needy boy.

Kirishima let out a chuckle when he saw Bakugo's eagerness as he pulled his fingers out of him earning a whine at the loss of touch.

"Give me a second to lube up unless you want me to dry fuck you." Kirishima laughed as he began to lube up his hard dick before lining up to Bakugo's entrance.

"Hurry up~" Bakugo whined showing off his wanna-be power bottom side.

"You said be gentle so I'm being gentle," Kirishima said back calmly as he began to press into his lover.

"F-fuck, you're so tight, baby." Kirishima groaned out, loving the tight feeling around his cock.

"God you're so big," Bakugo said back once Kirishima was fully inside of him, stilled so he could adjust.

"And you're taking me so well baby, you're doing great." Kirishima praised as he peppered kisses all over Bakugo's face, kissing everywhere but his lips.

"Give me a real kiss dammit!" Bakugo said as he grabbed the back of Kirishima's head and pulled him into a real kiss.

Kirishima laughed into the kiss before pulling away.

"Can I move now?" He asked seeing as it had been a few minutes now.

Bakugo nodded so Kirishima began to slowly move in and out making sure Bakugo would feel every inch of him.

He slowly gained speed and after a while had to restrain himself from going too hard and possibly hurting Bakugo.

"Fuck Eijiro~!" Bakugo moaned out "More! Harder, faster!"

That's all it took for Kirishima to snapp, his thrusts became faster, deeper, and harder than before.

He began to move at different angles to see if he could find Bakugo's prostate.

"AaH~ Fuck! There! Please, please, please, Eijiro don't stop! More, more, more, fuck!" Bakugo begged and rambled on, pleading for Kirishima not to stop and give him more pleasure as he hit the bundle of nerves he had been looking for.

Kirishima had a thing for begging. It was a major turn-on for him so he complied and continued to ram into his lover's prostate over and over again.

"I'm close!" Bakugo moaned out but Kirishima didn't slow down any, if anything he sped up.

Bakugo's legs began to shake and his vision went a blurry white as the coil knot in his stomach let go, his cum shooting from his cock and falling onto his chest, a loud moan of Kirishima's name coming from his lips.

Kirishima slowed down some but not much making Bakugo whine at the pain and pleasure of overstimulation.

"I know, I'm close baby, just a few more," Kirishima reassured, internally wondering how Bakugo was going to last through all night when it was just now ten.

After a few more thrusts Kirishima buried himself deep into Bakugo as he came with a low moan, filling Bakugo up to the brim.

"Aah~" Bakugo moaned at the feeling of being filled with his lover's seed.

Kirishima gave a few more slower, calmer thrusts before pulling out getting another whine from Bakugo.

"Are you sure you want to keep going?" Kirishima asked getting a quick nod from Bakugo.

"Okay then what next?" Kirishima asked before he began to lick up Bakugo's cum off of the boy's chest.

"V-vibrators?" Bakugo asked as he glanced over at the closet where they kept all of their sex toys.

"Whatever you want baby," Kirishima replied before finishing cleaning Bakugo off with his tongue.

He got up and went over to the closet where he pulled out a rather large box full of sex toys, extra lube, extra condoms, and other things.

"Which vibrators do you want to use baby?" Kirishima asked seeing as they had five different ones.

"High-level ones." Was Bakugo's only answer getting a nod from the boy.

He picked out a baby blue, seven-inch vibrating dildo and then a hot pink, five-inch vibrator before putting the box back.

He then moved back over to the bed, lubing up the dildo before pressing it into Bakugo.

"And you're positive you are okay with this overstimulation?" Kirishima asked as he put the vibrator at the base of Bakugo's cock, not turning on either one of them yet.

"Yes I'm sure, please for once stop being such a gentleman and just fuck me." Bakugo pleaded as he arched his back, trying to fuck himself on the dildo.

"Okay, okay." Kirishima laughed before turning both vibrators on.

He turned the one in Bakugo's ass up to seven out of ten and the one on Bakugo's cock up to fifteen out of twenty instantly getting loud moans from the blond.

Kirishima used one of his hands to move the dildo in and out of Bakugo he used the other hand to move the smaller vibrator up and down Bakugo's shaft.

After trying a few different angles Bakugo moaned even louder than before as his babbling began again.

"Fuck Eji- there! Please! Fuck!" He pleaded as the dildo hit his prostate.

Kirishima turned the vibrations up to ten on it and circled it on Bakugo's prostate sending Bakugo over the edge, his cum going all over the smaller vibrator in the process.

"Don't stop! Fuck Ejirio! Please don't stop!" Bakugo pleaded feeling needy for more.

Kirishima complied and continued to abuse the bundle of nerves as he moved the vibrator up to the tip of Bakugo's dick, circling both sensitive areas with the vibrator.

"FUCK! Aaah~!" Bakugo moaned out as he came for the third time that night, his legs shaking, back arching, toes curling, and vision going white again.

"Do you want me to stop now?" Kirishima asked as he pulled the smaller vibrator away from Bakugo and turned off its vibrations seeing as it was completely covered in Bakugo's cum now. Yet he left the vibrating dildo inside of Bakugo, right on his prostate.

Bakugo nodded so Kirishima pulled the vibrator out of him and turned the vibrations off.

"Do you want to stop now? It's already twelve." Kirishima asked as he set the vibrators aside, knowing that he was going to have to clean them off later.

"No, I wanna ride you," Bakugo answered as he sat up, wincing at the slight pain from his ass.

"Are you sure about that baby? You don't look like you have the energy to ride me." Kirishima said even though he would love Bakugo to ride him and help him with his painful hard-on.

"Yes, I can ride you, get the butt plug though," Bakugo said confusing Kirishima.

"How are you supposed to ride me if you have a butt plug in?" He asked sounding confused. Yet he still got up and grabbed the butt plug out of the box of toys.

"It's for after I ride you," Bakugo said as he looked away with an embarrassed blush.

"Oooh okay." Kirishima nodded acting as if he understood even though he still didn't.

Bakugo took the plug from Kirishima and set it beside of them before moving so he was strattling Kiri, their dicks pressed against one another making them both let out breathy moans.

Kirishima grabbed the lube and started to lube up his dick for Bakugo, his other hand giving Bakugo a handjob while he waited.

Soon enough Kirishima pulled his hands back from both of them before helping Bakugo line up with his cock and slowly lower himself onto it.

"Fuck~" Bakugo moaned out as he lowered himself completely down onto Kirishima now balls deep inside.

Bakugo grinned his hips down making them both moan as Kirishima connected their lips into a kiss.

After a while of adjusting to Kirishima's huge size, Bakugo began to bounce up and down slowly.

Suddenly Bakugo pulled almost completely all the way off of Kirishima before slamming himself back down getting loud moans from both males.

"Fuck Katsuki~!" Kirishima moaned as he put his hands on Bakugo's hips, helping him go up and down at a faster speed than before.

He soon began to thrust his hips up with every bounce causing them both to become moaning messes from the pleasure.

"I'm close~" Bakugo warned making Kirishima move one of his hands onto Bakugo's dick, pumping up and down in time with the bounces and thrusts.

"Eijiro~!" Bakugo moaned as Kirishima hit his prostate.

"Fuck, fuck, fuck, more, harder, please~" Bakugo babbled as he struggled to keep going, his legs were giving out on him but he wanted more.

So Kirishima, being the amazing husband he is, turned the so Bakugo was lying on the bed once again and then proceeded to ram into Bakugo's bundle of nerves over and over again.

"Ah fuck Eji~!" Bakugo moaned out so loud that the next-door neighbors could probably hear him as he came.

"Katsuki~!" Kirishima moaned out as he too came, deep inside Bakugo.

Bakugo's eyes rolled back at the feeling as Kirishima began to pull out only to be stopped by Bakugo's legs wrapping around him.

"Stay." He attempted to demand but there wasn't anything but tiredness in his tone.

"Okay, baby." Kirishima agreed as he continued to slowly thrust in and out, mostly just trying to get over his high.

Well, that was the plan anyway.

"Why are you going so slow? Speed up." Bakugo whined confusing Kirishima.

"How are you not tired of this?" He asked as he sped up some.

"Because it's all coming from you and I love you. You know I have a killer stamina when I'm horny." Bakugo answered with a chuckle getting a chuckle back.

"Love you too," Kirishima said as he kissed Bakugo.

A while later Bakugo came for the last time and Kirishima came again, filling Bakugo up once again. Now he was extra full considering the first load wasn't let out.

"Can I pull out now?" Kirishima asked getting a nod.

So the redhead pulled out of Bakugou and Bakugo handed him the buttplug.

Still confused Kirishima put the plug into Bakugo's ass but didn't question anything.

"Now we need to go and take a shower," Kirishima said as he stood up before turning around and picking Bakugo up knowing that the boy wouldn't be able to walk for the next few days.

"But it's only -(he looked over at the clock)- two in the morning." Bakugo pouted as Kirishima walked them to the bathroom.

"We fucked all night, two in the morning is the morning time baby. We need rest now, you aren't going to be able to walk for a while so we are both going to have to use up some of our vacation days to take care of you." Kirishima reasoned as he set Bakugo down on top of the toilet as he turned to the shower.

"Fine." Bakugo agreed but only because he was fucked out and tired as shit.

"Come on baby, you just have to stay awake long enough to shower your body. We can take a proper shower tomorrow." Kirishima said as he helped Bakugo stand, the blond wincing as he did so.

Now that the water was hot, Kirishima helped Bakugo bathe his body before cleaning himself off quickly.

They got out of the shower and Kirishima helped dry Bakugo off with a towel before drying himself off.

He then picked Bakugo up again and carried him into the guest bedroom knowing that they would have to change the bedsheets of their bed tomorrow as well.

"I love you," Bakugo said out of the blue as Kirishima laid him down on the bed before laying down next to him.

"I love you too." He replied as Bakugo cuddled up to his chest.

"Goodnight baby," Kirishima said before kissing the top of Bakugo's head and wrapping his arms around Bakugo's still naked body.

"G'night," Bakugo mumbled back before falling asleep.

Kirishima quickly followed him and succumbed to slumber.
