"Hey, what was that for?" Mikasa grumbled, it was too sudden of an attack for her to be mentally prepared.

Tatsuya looked into her eyes as a smile appeared on his face. Mikasa was a bit shorter than him, so when she was sitting on his lap, her face was on the same level as his.

Before Mikasa could say anything, she again felt his right hand playing with her ass cheeks as a moan escaped her mouth. "Aaaaah~."

It wasn't that she was sensitive, he just knows how to please her. After some 'research' that Tatsuya did a few years ago, he realized that Mikasa's weak spots didn't change even if she had a new body, which was a plus for him.

As she moaned, Tatsuya suddenly kissed her, invading her mouth with his tongue. Mikasa welcomed his tongue as they started a battle for dominance as the kiss grew sloppier every second. Tatsuya raised his right hand from her ass before.

Spank*

"Mhmmmm~" He smacked her plump and juicy ass hard enough for her to moan inside his mouth as she stopped moving her tongue against his, letting him do as he pleased inside her mouth.

His right hand made its way inside her shorts before it started playing with her ass, doing as he pleased. Mikasa, who was vulnerable at this point, wasn't able to do anything but moan inside his mouth.

After a few minutes, Tatsuya decided to let go of the kiss before he removed Mikasa's top while putting his t-shirt inside the inventory. It wasn't hard to remove her top as she raised her hands, cooperating with him.

"Damn." Tatsuya muttered, looking at Mikasa's upper body, no matter how many times he sees it, the excitement doesn't vanish. She was wearing a white laced bra, complimenting her fair skin and long, black hair. With a slim waist and perfect abs, she had an hourglass figure. His left hand trailed off as he caressed her perfect abs.

"Mhhhmm~" Mikasa mewled as Tatsuya kissed her neck while his left hand was still crashing her abs. Tatsuya moved his right hand from her butt before he caressed her back. Even if she had ripped muscles, Mikasa's body was soft and very nice to touch.

Click*

With a click, Tatsuya's right hand opened the clip of her bra before throwing it off. Gaining full view of her modest yet beautiful breast before he made his way towards it. He looked at her slightly pink nipples that were hard from excitement.

Opening his mouth, he took her right nipple inside his mouth, sucking it hard enough so that it'll leave marks later while his left hand kneaded Mikasa's right breast, playing with her nipple, slightly pinching and twisting it.

"Aaaaaahhhhhhhn~" A loud, erotic moan escaped Mikasa's mouth as she arched her back at his ferocious sucking. If it wasn't for his right hand supporting her, she would've fallen back at this point.

Tatsuya's left hand moved away from her breasts, making its way towards her mouth before inserting his index finger into it. Mikasa instinctively started sucking his finger. He withdrew his finger from her mouth after it was wet enough, making its way toward her ass.

"Aaaaaaahhhnnnn~" Mikasa gave another erotic moan as she felt something entering her asshole. Before she could get used to it, Tatsuya started moving his finger back and forth inside her while his mouth was now assaulting her left nipple after leaving a red mark around her right nipple.

Noticing that she was about to cum, Tatsuya started sucking her breasts even more ferociously while increasing the speed of his index finger. And decided to give the final blow with his right hand which was supporting her.

Spank*

"Aaahhhhh~ Aaahhhhhh~ Ahnnnnn~ I'm cumming~" Mikasa announced as she came, drenching her shorts in perverted juices.

Before she could rest, Tatsuya started kissing her again. She was too horny to be satisfied with a kiss alone as she tossed both Tatsuya's and her shorts inside the inventory.

"Mmhhhmmm~" She moaned inside his mouth as she felt his dick rubbing against her clit.

Tatsuya let go of the kiss and he moved his hands before grabbing Mikasa by her waist and gently placing her on the best, her back facing the bed, revealing her pussy to his greedy eyes before he used his right hand to insert his middle and index finger inside her wet folds.

'She's totally wet.' He thought. She was definitely ready for him to take her virginity, but he decided to mess with her for a bit.

He fingered her with his fingers while his thumb rubbed her clit, making Mikasa moan in pleasure. She was too sensitive after cumming not too long ago.

"Ahhhnn~. Fuck me already." Mikasa said in a hoarse voice. Hearing her, Tatsuya smirked before he grabbed both her thighs with his left hand, raising her ass in the air.

"Now, it's punishment time." Tatsuya said with a grin, looking at Mikasa.

"H-Hey, I am way too turned on for that." Mikasa pleaded, but her pleas were never answered as he raised his right hand.

Spank*

"Aaaaaahnnn~" He spanked her hard enough to make her ass cheeks and thighs jiggle. Mikasa came a little at the hard spank.

"Someone has been enjoying herself a lot."

"P-Please, forgive me." Mikasa pleaded again. Tatsuya smiled at her. Every sadist is a hidden masochist. Mikasa was the first one who made him realise that.

"Your apology isn't serious enough."

Spank*

"Aahhhhhnnnnn~" With another hard spank, Mikasa came again. After repeating this scene for more than fifteen minutes, her ass was red so Tatsuya decided to give her what she wanted.

He let go of her legs before she opened them, making an 'M'. It was a clear invitation, but he wasn't moving. Mikasa understood what he wanted before she spread her pussy with her hands.

"Please, fuck my brains out. Punish this miserable bitch as much as you wish. Discipline me until I behave exactly as you wish for me to~." Mikasa said, playing with herself. She knew that it was futile. Tatsuya knew how big of a masochist she was when facing him.

Tatsuya grinned again before making his way between her legs, placing his dick just an inch away from her pussy. He pushed his dickhead inside her pussy, there was a slight resistance before.

"Aaaaaahhhnnnnnnnnn~" Mikasa moaned at the top of her lungs as Tatsuya inserted his 8 inches long dick inside her in one go. His dickhead slamming against her womb. She wrapped her legs around his waist, her soft and smooth thighs rubbing against him. Losing her virginity in such a brutal way wasn't painful at all, but immensely pleasurable. She had some tears forming at the corner of her else.

Still balls deep inside her, Tatsuya leaned forward and started kissing her. She wrapped her hands around his neck while kissing him back. After a minute of kissing, Tatsuya decided that it was about time he started moving. He started moving at a rather fast pace for someone's first time.

"Ah~, Mmmhhh~ Faster~" Mikasa moaned as she felt like she was just at the doors of heaven.

Hearing her words, Tatsuya started to move faster as his dickhead was continuously slamming against her womb.

"Aaaahh~"

"Aaaaahhhhnnnn~"

Mikasa was moaning like a bitch in heat. Tatsuya slowed down before pulling his dick back until only the dickhead remained inside her before pushing it back inside with full force and doing her at an even faster pace than before.

"Aaaaahhhhhhnnn~" Mikasa continuously moaned.

Splash* Splash*

Mikasa came all over Tatsuya's crotch but the latter continued to fuck her senseless, her eyes were clouded with pleasure and her expression was just begging for more.

Pah* Pah* Pah* Pah*

The sound of Mikasa's ass clapping against Tatsuya's things resounded along with the former's loud moaning. Mikasa raised her hands before pulling Tatsuya down into another hot kiss.

Tatsuya didn't slow down even while kissing as Mikasa continued to moan inside his mouth.

Tatsuya let go of the kiss before looking at Mikasa. She had a perfect ahegao as she drooled from the corner of her lips. Her breasts and abs were covered in a thin layer of sweat as they jiggled against his constant thrusting.

"I'm about to come" Tatsuya said as he increased the pace even more. He leaned before opening his mouth and started sucking on Mikasa's nipples again.

"AH~ Do it Ah~ Aaaaahhhnnn~ inside. Aaah~"

After another minute of this heaven, Mikasa felt something got filling her womb as Tatsuya came inside her without restraint while biting her nipple as his other hand played and kneaded her breasts into his desired shape.

Squirt* Squirt*

Mikasa came again, wetting the bed along with Tatsuya's crotch.

Plop*

Tatsuya pulled his dick out of her pussy as his cum, mixed with her juices started flowing out of it. Watching it, he got hard again, looking at Mikasa like a predator.

"Mikasa." He looked at her with a smile, ignoring her pleading gaze. Unlike him, Mikasa didn't train for her abs or muscles, so her stamina was nowhere near his level. He thoroughly enjoyed the look on her face as he said what he wished her to do.

"On all fours, now."

Mikasa, being the obedient girl she is(only in bed), got on all fours. Her plump and juicy ass faced him as his cum came out of her pussy even now. He wasn't worried about getting her pregnant, they were both medical ninjas, how could they make a mistake like that?

He smiled, looking at her perfect backside as he spanked her ass again, making it ripple before he started playing with them, spanking them now and then. Mikasa was continuously moaning, thoroughly enjoying each spank as she felt his dick rubbing against her clit again. But this time, he was intentionally rubbing it hard enough for her tongue to roll out as she drooled like a bitch.

"Let's see how much you can take." He said before roughly inserting his dick inside her pussy before he started pounding her.

"Ah~"

"Aaaaahhhnnn~"

"Harder~"

Mikasa continuously moaned throughout the night. Both of them were so horny at this point that they forgot that there was someone else living with them now.

Tsunade, who has been watching this act of shamelessness through the small hole she created to keep a check on them was drooling, imagining herself at Mikasa's place before she pushed that thought to the back of her head. But unknowingly, her right hand went towards her crotch as she started rubbing herself, regret covering her heart along with a lot of guilt.

"Maybe it isn't a bad idea." Tsunade muttered. Her cheeks flushed red as a crazy smile appeared on her face. If Tatsuya or Mikasa were here, they would recognize the signature smile of a Yandere on Tsunade's face.

A/N- As of now, every 100 power stones will result in an R-18 chapter or a backstory one💀

Or should I mention small smuts now and then within normal chapters rather than bonus chapters? But that'll give everyone sudden horny attacks, would be troublesome if someone got hard on a public transport💀
