9. Stronger

(Warning: this chapter has NSFW content)

Krillin could feel his strength building as the bullets bounced off of his impenetrable skin and he rushed the assailants. In less than a minute the men were on the ground unconscious and Krillin felt the strongest he'd ever been. He was going to test that theory today. Training with Goku was doing miracles for his strength, so now he would have a daylong session with Piccolo in the hyperbolic time chamber. In only one day he would get the training of an entire year.

He waved goodbye to the other police officers who were still stunned at his display of heroics and hopped on his motorcycle. He changed at the precinct into his fighting Gi and then shot up into the air towards Dende's tower.

Piccolo was waiting for him patiently at the entrance of the chamber. "I can feel that you have grown stronger Krillin, I am impressed."

"Stronger than before? Like when I was still fighting?"

"Yes," Piccolo said. "You have surpassed any of the other humans, even Tien and Yamaha."

Krillin beamed. The news of that made him happy. He felt strong and refueled.

"After we complete our training I am confident you can match up to Goku at Super Saiyan level."

Krillin nearly laughed aloud. "Don't push it Piccolo. If I am able to beat Goku at his regular level I'll be happy."

"You already can do that Krillin," Piccolo said with a smirk. "Goku fights with all brawn and you use your brain."

Krillin thought about that a moment. As children Goku was always stronger than him but Krillin often defeated him because of his wittiness. Piccolo opened the door to the chamber and said, "ready?"

Krillin nodded with determination and followed him inside.

…

18 had grown accustomed to seeing Krillin every single day. When they were dating and even engaged they would go a few days without seeing each other and it would be fine, but now on the first day of Krillin's absence 18 was starting to feel anxious and nervous as if having withdrawal from a drug. Marron was satisfied with the answer "daddy went to go get stronger with Uncle Piccolo" and went right to bed with a smile on her face. 18…not so much.

Needless to say she was irritated to no end the following morning. Androids didn't need to sleep so she didn't feel tired but she very much liked her cuddle-with-husband routine, so she was grumpy. She left Marron at Chichi's for a play date just to spare the young girl from her frustration.

Then to top it all off Krillin arrives later than expected. His Gi was all torn up, he had scratches and bruises and sweat everywhere. "Hey," he said with a soft smile shrugging off his Gi shirt and kicking off his pants as he entered the house. In just a black T shirt and shorts 18 could see just how giant his muscles had gotten.

His arms were thick and veiny with pure muscle and she swallowed loudly. It was loud enough to catch his attention.

"Are you okay?" He said completely oblivious to her predicament.

"You…you look good," she muttered cheeks flushed and eyes darkening with lust.

"Yeah?" Krillin said with a grin. "I mean I'm all scratched up from that last fight with Piccolo and all sweaty…"

Before Krillin could finish 18's fist was nearly connecting to his face. He moved quickly without thinking about it and caught her fist in his hand. 18's eyes widened in surprise.

Narrowing her eyes in determination she swiped her leg around to kick him in the chest but he dodged it so quickly she didn't even see him move. She lunged forward again throwing punches and kicks with all her strength even though she knew she could seriously hurt him but she couldn't even get a hit in.

He was behind her suddenly and she couldn't react as his hand came down against her back and sent her hurdling towards a wall. He didn't even hit her hard enough to cause any real damage or even break through the wall of the house but he still sent her flying as if he has swatted a fly.

She tried to get up to continue fighting but he shoved her back down to the ground and pinned her there.

They had done "pinning" activities in the bedroom but every time 18 lost her patience she very easily got out of Krillin's grip and then pinned him down. This time though, no matter how much she struggled she couldn't break free.

(NSFW content now)

He was stronger then her and the more she struggled the tighter he held on. 18's breath came in harsh pants and she could feel the undeniable wetness in between her thighs. Part of her was frustrated that he was actually stronger than her and the other part absolutely loved it.

Krillin' face was crunched in concentration trying to keep her down as she fought but 18 could feel his hardness pressing against her hip.

18 couldn't take it anymore. She was never EVER the one to break during sexual encounters with Krillin. She would often initiate but he was always the one who turned into a shuddering mess who couldn't control himself. She always used her sex appeal and her superior strength to control him like a puppet, but now he was the puppeteer.

She briefly wondered why she hadn't let him really take control until now because she felt so hot she thought she would burn a hole through the floor. She surged upwards and pressed her lips against his hard. He was taken by surprise and released his grip.

She slammed him against the nearby wall with the force of the kiss and gripped him through his shorts. He was not just hard he was twitching.

"K-Kami 18," he breathed as she slid down to her knees and yanked his shorts off. His erection sprung free nearly hitting 18 in the face but she didn't care as she gripped him tightly and wrapped her lips around him.

Krillin grunted and gripped her hair. Being in the chamber was tough for him. He and 18 had a very good sex life. Granted it wasn't as active as Vegeta and Bulma's, but they both were pretty insatiable and they never went more than a week without it. He had lived an entire year in that chamber doing nothing but focusing his mind and training.

18 stopped abruptly with a shout of pain. Krillin looked down in surprise and saw that he had actually hurt her when he pulled her hair. That never happened…EVER.

"Oh Kami 18 I'm sorry! I didn't mean…"

"Do it again."

Krillin gulped. "What?"

"Do it again," 18 said biting her lip.

Krillin slipped his fingers into her hair and tugged hard. 18 cried out again and gripped his thighs. Krillin yanked her to her feet, twirled her around and shoved her against the couch.

He placed a hand on her shoulder and leaned her over the arm of the couch until she was face down against the cushions. "You like my strength?"

"F-fuck…yes Krillin. Yes!"

He gripped her jeans and ripped them clean off effortlessly. She moaned as he rubbed his hands over the smooth skin of her bottom. He yanked off her panties settled behind her.

He didn't plunge in though, just pressed himself against her until she whimpered. "You like it when I hurt you?" He said lifting his hand and slapping 18's butt cheek hard.

18 cried out. "Yes! Krillin! Fuck again!"

He spanked her again harder.

"Again!"

SMACK!

"Uhhh again!"

SMACK!

"Fuuuuck again! Again!"

SMACK SMACK SMACK!

"Kriiiilllinnn! Fuck me! Fuck me hard!"

She didn't need to say it twice. He pushed into her soaking vagina easily and immediately started thrusting. He knew he wouldn't last long but neither would she. Her hands clawed at the couch desperately and her moans were so loud Krillin was sure all of the Z fighters with advanced hearing could hear.

Sweat coated both of their bodies and Krillin was so close he could feel the tingling rising up from his toes. He thrust faster and harder but now knew he could hurt her so he was mindful. 18's walls were tightening around him and he gripped her hips to try to hang on a little longer.

"Don't stop! Kami Krillin I'm gonna…I'm gonna cum…ohhhhhhh Kriiiillliinnn!"

Krillin felt the heat at the pit of his stomach but grit his teeth until 18 got there. The moment he felt the spawning, saw her trembling body nearly flying off the couch in pleasure, and heard her piercing cries he released himself with a long groan.

He let himself plop down against her sweaty back panting heavily. 18 remained still, breathing hard not bothering to move the strands of blonde hair that were matted against her forehead and cheek, or even open her eyes.

(It's safe to read now)

He pushed the hair away from her face and gently kissed her temple before stepping away from her.

"I didn't hurt you did I?"

To that 18 did react. She began laughing and she slowly rose from the couch and turned towards him. "Oh yeah you did hurt me but I liked it."

Krillin blushed.

"Enjoy it while it lasts Krillin cause now I'm going to start training too," 18 said with a smirk. "Let's see how much longer you'll be stronger than me."
