"Poof."
The little cloud of smoke from the magic trick floated up to the ceiling of Master Roshi's small house on the island. The old man let out a happy laugh and fell back onto his bed with a soft thump. He stretched his arms up and crossed them behind his bald head. His sunglasses glinted in the sunlight that came through the open window.
"That went well," Roshi said to himself, his voice full of excitement. "Now let's see how far this gets." He grinned wide, showing all his teeth. "I can't wait to hold some boobs." He closed his eyes and pictured it, still smiling like a kid who just found a new toy.
Far away, in the big city of West City, inside the tall building of Capsule Corporation, things were not so calm.
Bulma Briefs stood in the bedroom she shared with her husband, Vegeta. The room was large and modern, with big windows that looked out over the city. The bed was huge and covered in soft blue sheets. Bulma had one hand tight around Vegeta's ear. She pulled him down so his face was close to hers. Her blue hair bounced as she moved, and her eyes were full of fire.
"You Saiyans are as stupid as they come," she said loudly. "You always listen to nonsense. How can you believe something so dumb?"
Vegeta, the proud Prince of Saiyans, made a face. His spiky black hair stood up like always. He wore his usual blue training suit. The ear Bulma held hurt a lot.
"Ouch, ouch, Bulma, that's painful as fuck," Vegeta groaned. His voice was deep and rough, but right now it sounded like a little boy who got caught stealing cookies.
Bulma did not let go right away. She kept talking, her words fast and angry. "You have always had unlimited potential to grow. You get stronger through hard training. You get stronger through rage in battle. That is how Saiyans work. We know this. And yet, you and Goku both believe such rubbish from the mouth of a crazy angel!"
She finally let go of his ear. Vegeta rubbed it with his hand, his face red from pain and maybe a little shame. Bulma turned and walked to the big bed. She climbed up onto it slowly, sitting on the edge first, then moving to the middle. The mattress sank a little under her weight.
Vegeta watched her. He stood still for a moment. Then he spoke, his voice softer now. "Bulma, truthfully... Whis is not wrong."
Bulma turned her head fast to look at him. Her eyes were wide. "What did you say?"
Vegeta took one step closer to the bed. Then another. He came to the bedside where his wife sat. "When we fuck, I usually gain a little energy from you. It is small, but it is there. I feel it."
Bulma opened her mouth to say something angry, but no words came out at first. She just stared.
Vegeta kept talking. "I wouldn't act like Kakarot. I would never do that. My dick is for only you." As he said this, his hand moved slowly. He reached out and gently touched her ass. His fingers were warm through the thin fabric of her shorts.
Bulma felt the touch. It was soft, but it made her whole body pay attention. She turned fully to face him now. "Do you mean it, Vegeta?" Her voice was not loud anymore. It was quiet, almost a whisper. Their eyes met. His dark eyes looked into her bright blue ones.
Vegeta did not look away. He grabbed her waist with both hands now. His grip was strong but careful. Bulma placed one hand on his face. She touched his cheek, feeling the short hairs of his beard.
"I do," Vegeta said. "I swear it on my Saiyan pride." His eyes became serious. There was no joke in them now. This was the prince speaking from his heart.
For a long moment, they just looked at each other. The room was quiet except for the soft hum of the air system and the far-away sounds of the city. Then, slowly, both moved at the same time. They closed what little distance remained between them. Their lips met in a kiss. It started soft, just a touch. Vegeta lifted one hand and held Bulma's face gently, like she was something precious. They moved together onto the bed. Bulma ended up on top, her legs on either side of Vegeta's hips.
The kiss grew deeper. Bulma made a small sound in her throat. Then, suddenly...
"Slap."
Vegeta's hand came down on her ass. Not too hard, but enough to make a sharp sound. Bulma pulled back from the kiss just enough to let out a moan. "Ahh."
She looked down at him, her face flushed pink. Her eyes sparkled with something new—excitement, maybe a challenge. "Spank my ass harder, Vegeta," she commanded. As she spoke, she moved her hips. She whined on his rod, feeling him hard beneath her.
Vegeta's lips turned up in a small smile. He liked when she took charge like this. "As you command, my queen," he replied. His voice was low and full of respect, but also full of want.
He lifted his hand again.
"SLAP."
This one was harder. The sound filled the room. Bulma's body jumped a little at the impact. "Ah, that's my prince," she exclaimed. Her voice was breathy. She leaned down and kissed him again. This kiss was hot and messy. Tongues touched. Hands moved everywhere.
Bulma's hands went to Vegeta's chest. She pushed his training suit up, wanting to feel his skin. Vegeta helped her pull it off over his head. His muscles were hard and defined from years of training. Scars crossed his chest and arms—marks from battles long ago. Bulma traced one scar with her finger, then kissed it.
Vegeta's hands were busy too. He grabbed the bottom of Bulma's shirt and pulled it up. She lifted her arms so he could take it off. Underneath, she wore a simple black bra. Vegeta reached behind her and undid it with one quick move. The bra fell away. Her breasts were free now. They were full and perfect. Vegeta stared for a second, then cupped one in his hand. He squeezed gently.
Bulma moaned again. She ground her hips down harder on him. She could feel how much he wanted her. It made her feel powerful.
"More," she said. "I want more spanking."
Vegeta did not need to be told twice. His hand came down again.
"SLAP. SLAP. SLAP."
Three in a row, each one a little harder. Bulma's ass turned pink under her shorts. She cried out with each one, but they were happy sounds. Her body moved with the rhythm. Up and down. Back and forth.
Between spanks, Vegeta kissed her neck. He kissed her collarbone. He kissed the tops of her breasts. Bulma's hands were in his hair now, holding his head close.
"Take these off," Bulma said suddenly. She sat up straight and pulled at her shorts. Vegeta understood. He helped her slide them down her legs. Her panties came off too. Now she was naked on top of him. Vegeta looked at her body like it was the most beautiful thing in the universe.
Bulma reached down and pulled at Vegeta's pants. He lifted his hips so she could pull them down. His cock sprang free—hard, thick, ready. Bulma wrapped her hand around it. She stroked slowly, up and down. Vegeta groaned deep in his chest.
"You are mine," Bulma said. "Only mine."
"Only yours," Vegeta agreed. His hands went to her hips. He guided her as she lifted up. Then, slowly, she lowered herself onto him. They both made sounds when he entered her. Bulma was wet and warm. Vegeta filled her completely.
For a moment, they stayed still, just feeling each other. Then Bulma started to move. She rode him slowly at first. Up and down. Her hands on his chest for balance. Vegeta's hands on her ass, squeezing.
"Spank me while I ride you," Bulma ordered.
"SLAP."
The spank made her move faster. Another one.
"SLAP."
Bulma's moans grew louder. The bed creaked under them. The headboard tapped against the wall with each thrust.
Vegeta watched her breasts bounce. He reached up and played with them. He pinched her nipples gently. Bulma liked that. She leaned forward so he could take one in his mouth. He sucked and licked while she kept moving.
The energy Whis talked about—it was real. Vegeta felt it now. Every time Bulma came down on him, a little spark of ki flowed between them. It was small, like a warm buzz in his blood. It made him stronger. Not like a Super Saiyan transformation, but something quieter. Something personal.
Bulma felt it too. She always did. It was why she never minded when Vegeta trained for days. She knew their nights together helped him. But she would never admit she liked being his secret power-up.
"Harder," she said now. "Fuck me harder."
Vegeta grabbed her hips tight. He thrust up to meet her. The rhythm changed. Faster. Rougher. Skin slapped against skin.
*SLAP.* Another spank. Bulma's ass was red now. She loved it.
"I'm close," Vegeta growled.
"Me too," Bulma gasped. "Don't stop."
They moved together like a storm. Sweat made their bodies shine. The room smelled like sex and love and power.
Bulma came first. Her whole body shook. She cried out Vegeta's name. Her walls tightened around him. That pushed Vegeta over the edge. He thrust deep one last time and held her there. He came inside her with a loud groan.
For a long minute, they stayed like that. Bulma collapsed onto Vegeta's chest. His arms wrapped around her. They breathed hard together.
Then Bulma laughed softly. "Well? Whis was right."
Vegeta huffed. "Don't tell Kakarot."
"Never," Bulma promised. She kissed his chest. "This is our secret training."
They lay there as the sun moved across the sky. Outside, the city kept going. Inside, a Saiyan prince and his genius wife rested in each other's arms. Tomorrow there would be training, inventions, battles. But tonight, they had everything they needed.
Back on the island, Master Roshi opened one eye. He had fallen asleep dreaming. He sat up and scratched his beard.
"Well," he said to the empty room. "Guess I'll never know if it works." He lay back down and closed his eyes again. "Worth a try though."
And somewhere far above, Whis smiled as he watched through his staff. Angels always know more than they say.
