Strongest Superhuman System

Chapter 345: Exercise Reason (+18)

Mark grinned at Arit, and Arit yelped as Mark suddenly shot forward and grabbed her! They landed on the futon, and Mark wasted no time attacking her neck once more. Arit groaned as she pressed her hand against Mark's chest. Mark reached down under her skirt, and Arit jolted as she felt Mark press his hand against her clitoris through her underwear.

"M-Mark. We should use protection."

Mark growled in anger and completely ignored her statement while pushing her panties to the side and inserting two fingers in her. Arit moaned, and Mark growled in her ear.

"I'll be careful."

Arit knew that she should stop Mark and make him use protection. No matter how careful Mark is, there is no way they can completely avoid getting her pregnant, but Arit felt too good to stop Mark right now. She widened her legs to give Mark more access down there and kissed Mark hard enough to bruise a normal person!

Clothes were thrown off faster than either of them could remember, and before long, they were both naked. Mark aligned himself with Arit and started to enter her, and Arit groaned as she felt her eyes roll to the back of her head slowly. The futon under her made the sensation completely different from when they were doing it on a bed.

It felt like Mark was using even more force to enter her than normal!

"Fuck, you're tight."

Mark grunted at the back of his throat before he increased his force and slammed into Arit in one move!

Slam!

"Mmph~! Ugh! Ugh! Ugh! Ugh! Ugh!

Ugh!"

Mark wasted no time as he started to slam into Arit like a piston, almost driving her into the ground with the force of every thrust! Arit's hands were wrapped around Mark's shoulders, and she could feel her eyes tumbling to the back of her head every time Mark entered her!

His dick was hitting her cervix over and over again, but she didn't even register the slight pain from that as it was completely drowned out by the pleasure she was feeling.

"Faster~ Faster~!"

Slam! Slam! Slam! Slam! Slam! Slam!

Slam! Slam! Slam!

Arit's head was thrown back, and she could feel her orgasm shooting through her every time Mark slammed into her. After a few more times, Arit eventually lost all control over her legs as her orgasm hit her hard!

"NNGH!"

Arit's legs shot into the air, and her toes curled inwards as she opened her mouth wide with a groan! Her eyes finally rolled to the back of her head, and she felt every nerve in her body screaming in ecstasy as a massive orgasm hit her like a truck! Arit didn't even realize when she was about to pass out, and the next time she opened her eyes, they were poison yellow!

Mark was still moving even in the middle of her orgasm and Arit grabbed Mark's shoulders tightly as she felt him slamming into her like a piston!

"Fuck! Fuck! Fuck! Fuck me, Mark! Fuck me!"

"Open your fucking legs for me."

Mark grabbed Arit, turned her over, and pressed her head into the pillow while her ass shot up towards him. He held her head down with one hand and put the other hand on her lower waist as he knelt between her legs. Arit widened her legs obediently while breathing heavily and groaned as Mark began to slam into her with even more force than before!

Slam! Slam! Slam! Slam! Slam!

Arit was holding on to the pillow like her life depended on it! She couldn't move at all because of how Mark was holding her down, so she had to receive the full force of Mark's thrusts every time! She could feel a new orgasm getting close and knew that if she wasn't careful, she was really going to pass out this time!

Mark suddenly shifted a little, and Arit's eyes widened as she felt him hitting a sensitive spot inside her again and again!

"AH! AH! AH! Fuck! FUUUUCK!"

Arit buried her face in the pillow and screamed as she felt another orgasm hit her immediately, and her toes curled upwards as she felt Mark still hitting that sensitive spot! It was like Arit was a waterfall, and she just kept cumming hard every time Mark hit her there!

Mark continued his movements until he also felt his orgasm coming, and he groaned as he pulled out quickly before releasing on Arit's back! He squeezed Arit's ass around his dick and used it to get himself off, and he felt a small pang of disappointment somewhere inside him because he couldn't release inside her. He couldn't wait until she was in her safe period again.

He would fill her up like a fucking balloon.

After some time, Mark noticed that Arit was no longer moving, and he tilted his head to one side while glancing down at her. She was still awake, but there was a lopsided smile on her face and a huge blush across her cheeks as she stared into nothing. Mark leaned down and covered Arit's body with his own, and Arit reached out to hold his bicep softly as she heard him whisper in her ear.

"Don't tell me you're already tired. We just started."

Arit felt her core shiver as she heard Mark's deep voice, and she swallowed while praying for strength as she felt him entering inside her again. Arit was slowly realizing with growing horror that she couldn't handle Mark's libido on her own.

...

Thirty minutes and no less than ten orgasms later, Arit was on top of Mark, slowly bouncing up and down as she impaled herself on his dick over and over again. Mark was sitting up and hugging Arit tightly against his body, and Arit's hands were on his shoulders as she felt her pussy stretching to the limit every time she went down on Mark.

Squelch! Squelch! Squelch! Squelch!

Her pussy made a wet, sloppy sound every time she moved as a result of how wet she was, and Arit found it easy to slide down on Mark because of this.

Anyone who entered her room at this moment would recoil from the intense, smoldering smell of sex that had permeated the entire room. There wasn't a single part of the room that didn't have Arit's juices on it, and Arit could feel tiredness starting to creep in. Even though Arit had enough stamina to be regarded as an S rank, she still couldn't keep up with Mark.

Mark looked like he hadn't even broken a sweat. That sadistic grin was still on his face, and when Arit looked down at him, she could see in his eyes that he was still rearing to go for another round.

Mark reached out and grabbed Arit's breasts in his mouth, and Arit moaned his name breathlessly while she sped up her movements. Mark's hands went to her ass and made her speed up even more, and Arit bit her bottom lip while pressing her chest into Mark's mouth.

Mark pulled back and grunted.

"Fuck, I'm close."

Arit felt Mark growing bigger inside her, and in the heat of the moment, she said something insane.

"Inside~ Do it inside, Mark. Fucking breed me."

It was like a switch was flipped inside Mark's mind.
