The sun was setting over the Son family home, painting the sky in shades of orange and pink that would have made a Super Saiyan blush. Chi-Chi stood at the kitchen sink, washing dishes with the same fierce concentration she applied to everything in her life. She was a woman of strong opinions and stronger will, the wife of Earth's greatest warrior, the mother of two half-Saiyan boys.
But lately, something had been missing.
The doorbell rang. Chi-Chi wiped her hands on her apron and went to answer it, expecting perhaps a delivery or maybe Goku returning early from training. Instead, she found Bulma standing on her doorstep, a strange smile playing at the corners of her lips.
"Bulma!" Chi-Chi said, surprised. "What are you doing here? Is everything okay?"
"Everything is better than okay," Bulma said, stepping inside without waiting for an invitation. "Can we talk? Privately?"
Chi-Chi nodded, leading her friend to the living room. They sat down, and Bulma immediately leaned forward, her eyes bright with a secret she was dying to share.
"I need to tell you something," Bulma said. "About Krillin."
"Krillin?" Chi-Chi frowned. "What about him? Is he okay? Is 18 giving him trouble?"
"Oh, he's more than okay," Bulma laughed, a low throaty sound. "Chi-Chi, I had sex with him. Last night. In my bed. While Vegeta watched."
Chi-Chi's mouth fell open. "What? Bulma, how could you? Vegeta is your husband! And Krillin is married too!"
"18 don't know about it ' ," Bulma waved a hand dismissively. So don't worry. And Vegeta..." Bulma's expression darkened for a moment. "Vegeta has been neglecting me for years. Do you know how small he is, Chi-Chi? Do you know what it's like to be with a man who has all that power but nothing where it counts?"
Chi-Chi looked away, her face flushing. She knew exactly what Bulma meant. Goku was the same. Strongest man in the universe, capable of destroying planets with a finger, but in bed... in bed he was quick and small and completely clueless about what a woman needed.
"Krillin is different," Bulma continued, her voice dropping to a conspiratorial whisper. "Chi-Chi, he's huge. Fifteen inches. Thick and hard and perfect. And he knows how to use it. He made me cum more times than I could count. He filled me with so much cum I was dripping for hours."
"Bulma!" Chi-Chi gasped, but she felt a strange heat building between her legs. "That's... that's..."
"Amazing?" Bulma supplied. "Life-changing? The best sex I've ever had in my entire life?"
Chi-Chi bit her lip. She had been with Goku since they were teenagers. She had never been with anyone else. And while she loved her husband, while she loved his kindness and his strength and his pure heart, she couldn't deny that the physical side of their marriage had always been... lacking.
"Goku is the same," Chi-Chi admitted softly. "He's so innocent. He doesn't understand what I need. When we have sex, he thinks it's just... just a game. Like the game we played on our wedding night. Like the 'special training' we did before the Cell Games. He doesn't realize it's supposed to feel good for me too."
"Then teach him," Bulma said, her eyes gleaming. "Or better yet, let me teach you both. Chi-Chi, I want to share Krillin with you. I want you to feel what I felt. And I have a plan."
"What kind of plan?"
Bulma leaned in closer, whispering her scheme. Chi-Chi's eyes grew wide, then wider, and finally, slowly, a smile spread across her face.
"You're crazy," Chi-Chi said.
"Crazy like a fox," Bulma grinned. "So? Are you in?"
Chi-Chi thought of Goku, of his innocent smile, of his complete lack of understanding about sex. She thought of Krillin, of Bulma's description of his massive cock, of the pleasure she had been missing for all these years.
"I'm in," she said.

Goku returned home just after dark, his stomach growling loudly. He had been training with Gohan all day, preparing for whatever new threat might be coming. As he walked through the door, he was greeted by the smell of his favorite food cooking, and by Chi-Chi wearing something he had never seen before - a red silk nightgown that left very little to the imagination.
"Chi-Chi?" Goku said, his head tilting in that adorable confused way he had. "You look different."
"Do you like it?" Chi-Chi asked, spinning around. "I thought we could play a game tonight, Goku. Remember the game we played on our wedding night?"
Goku's face lit up. "Oh! That game! Sure, I remember! It was fun!"
"And do you remember the special training we did before the Cell Games?" Chi-Chi continued, leading him toward the bedroom. "When we needed to make Gohan?"
"Yeah! That was a good training session!" Goku agreed happily.
"Well, tonight we're going to play a new version of that game," Chi-Chi said, opening the bedroom door. "And Krillin is going to help us."
Goku blinked as he saw Krillin sitting on their bed, wearing nothing but a pair of loose pants. "Krillin? Hey, buddy! What are you doing here?"
"Hey, Goku," Krillin said, trying to keep his voice casual even though his heart was hammering in his chest. "Chi-Chi invited me. We're going to play a three-player game tonight. It's... it's a new training technique."
"Cool!" Goku said, completely oblivious. "I love training!"
Chi-Chi closed the bedroom door and locked it. She had already sent Goten to spend the night with Trunks at Capsule Corporation, so they had the house to themselves. And she knew that Bulma was in her lab right now, watching through the hidden camera she had installed that afternoon. The thought of being watched, of Bulma seeing everything, only made Chi-Chi more excited.
"Okay," Chi-Chi said, her voice trembling slightly with anticipation. "Here's how the game works. I'm going to lie down on the bed. And you two are going to... to train me. From both sides."
"Both sides?" Goku asked, scratching his head.
"Yes," Chi-Chi pulled off her nightgown, standing naked before them. Both men stared at her - Goku with innocent appreciation, Krillin with hungry desire. "Krillin is going to train my front. And Goku, you're going to train my back. At the same time."
"Like double training?" Goku's eyes widened. "Wow, that sounds intense!"
"It will be," Chi-Chi promised, lying back on the bed and spreading her legs. She looked at Krillin, giving him a nod. "Krillin, why don't you show Goku what the first part of the training looks like?"
Krillin stood up, letting his pants fall to the floor. His cock sprang free, already hard and massive, fifteen inches of thick human meat that made Chi-Chi's breath catch in her throat.
"Whoa," Goku said, looking at his friend's cock with genuine curiosity. "Krillin, yours is way bigger than mine. How did you train it to get so big?"
"Lots of practice," Krillin managed to say, climbing onto the bed between Chi-Chi's legs.
"Can I watch first?" Goku asked. "I want to learn the technique."
"Sure," Krillin said, positioning himself at Chi-Chi's entrance. "Watch closely, Goku. This is how you properly train a woman."
And then he pushed inside.
Chi-Chi screamed. It wasn't a small scream or a polite moan. It was a full-throated, guttural scream of pure pleasure as Krillin's massive cock stretched her pussy wide, filling her completely in a way she had never experienced before.
"Oh god!" Chi-Chi cried out, her hands gripping the sheets. "Oh god, Krillin! You're so big! You're so fucking big!"
"Wow," Goku said, watching with fascination as Krillin began to move, his cock sliding in and out of Chi-Chi's pussy. "She really likes that training. Chi-Chi, are you getting stronger from this?"
"Yes!" Chi-Chi moaned, her hips bucking up to meet Krillin's thrusts. "Yes, Goku, I'm getting so strong! It's such good training!"
Krillin pounded into her, his hips moving with the speed and precision of a martial arts master. Each thrust hit deep, making Chi-Chi see stars, making her cum for the first time within minutes.
"Krillin! Oh god, I'm cumming! I'm cumming already!"
Goku watched his wife convulse in pleasure, her face twisted in ecstasy. "Wow, she never makes that face when I train with her," he said thoughtfully. "Krillin, you must be really good at this."
"I'm just getting started," Krillin grunted, flipping Chi-Chi over onto her hands and knees without pulling out. "Goku, this is where you join. The back training. You need to put your cock in her ass."
"Her ass?" Goku looked confused. "Are you sure? That's not where babies come from."
"It's a special advanced technique," Chi-Chi gasped, looking back at her husband. "It makes the training twice as powerful. Please, Goku. Put your cock in my ass. Join the game."
Goku shrugged, pulling off his orange gi. His cock was hard but small, barely five inches, thin and unimpressive compared to Krillin's monster. But Chi-Chi didn't care right now. She wanted them both. She wanted to be filled completely, to be ruined by these two men.
"Okay," Goku said, climbing onto the bed behind her. "Tell me if I'm doing it right."
He pressed against her ass, his small cock sliding in easily thanks to the wetness dripping from Chi-Chi's pussy. She groaned as she felt both of them inside her, stretching her front and back, filling her completely.
"Oh fuck," Chi-Chi moaned. "Oh fuck, yes. Both of you. Move together. Train me together."
Goku and Krillin found a rhythm, one pulling out while the other pushed in, creating a constant motion that made Chi-Chi scream over and over. The feeling of being double penetrated, of having two cocks moving inside her at once, was unlike anything she had ever imagined.
"How is she doing?" Goku asked Krillin, as if they were sparring partners checking on each other's form.
"She's doing great," Krillin grunted, his cock pounding Chi-Chi's pussy with brutal force. "She's taking it so well. Such a good student."
"Chi-Chi," Goku said, his voice innocent even as he fucked her ass. "Do you like this training? Does it make you happy?"
"Yes!" Chi-Chi screamed. "Yes, Goku, I love it! I love this training! Don't stop! Please don't stop!"
They kept going, Krillin's massive cock stretching her pussy while Goku's smaller cock moved in her ass. The contrast was incredible - Krillin's thickness filling her completely, hitting spots she never knew existed, while Goku's quick movements in her back added another layer of sensation.
"Krillin," Chi-Chi gasped, looking back at him. "Harder. Fuck me harder. Ruin me. Make me yours."
Krillin growled, gripping her hips and pounding into her with everything he had. The bed shook, the headboard slammed against the wall, and Chi-Chi's screams filled the room as orgasm after orgasm crashed through her.
One... two... three... she lost count as the pleasure became continuous, wave after wave of ecstasy that left her trembling and sweating and begging for more.
"Please!" she cried out. "Please, Krillin! Cum inside me! Fill me with your cum! I want to feel it!"
"Goku?" Krillin asked, checking with his friend.
"It's part of the game," Goku said happily. "Cum inside her! It makes the training complete!"
Krillin roared, his cock swelling even larger as he buried himself deep and unleashed. Stream after stream of hot cum flooded Chi-Chi's pussy, filling her completely, leaking out around his cock and dripping down her legs.
"Yes!" Chi-Chi screamed, her twentieth orgasm or maybe her thirtieth - she had lost count - ripping through her as she felt Krillin's seed filling her. "Yes! Oh god, yes! So much cum! There's so much!"
Krillin kept cumming, his balls emptying into her, painting her insides with his seed. It seemed to go on forever, pulse after pulse of thick white cum claiming her, marking her as his.
Finally, spent, Krillin pulled out, and a gush of cum followed, dripping onto the bed sheets. Chi-Chi collapsed forward, her body shaking, her mind blank with pleasure.
"Wow," Goku said, sliding out of her ass. "That was really good training. Chi-Chi, you did great!"
Chi-Chi could only moan in response, her body still twitching with aftershocks. She knew Bulma was watching, knew her friend could see everything, could see how thoroughly Krillin had claimed her, how completely he had ruined her for any other man.
"Can we do this training again?" Goku asked, his innocent eyes shining. "I really liked this game."
"Yes," Chi-Chi managed to whisper, reaching out to take Krillin's hand. "Yes, we can do this again. As much as you want."
Krillin smiled, looking down at his best friend's wife, at the woman he had just fucked into oblivion. He felt no guilt, only satisfaction. He had given her what she needed, what she deserved. And he knew this was only the beginning.
Somewhere in Capsule Corporation, Bulma watched the screen, her hand between her legs, already planning the next game.
