Vegito's energy sword shot through the air, spiking down into the crashing waves and finding its mark as a roar of pain tore up through the water. As the fused saiyan listed his arm into the air before him, the beam followed, and so too did the pink monster impaled on the bean's powerful shaft.

There held suspended in the air, growling with fury and dripping with salt water was the horrible villain Majin Buu. He shook with pure rage as he stared Vegito dead in the eye, his pink skin shining in the sun as it was reflected off of its rubbery wet surface. His orange and blue top was torn to shreds by the beam penetrating his middle, his white and usually baggy pants clinging to his legs as they sagged with pouring water.

Vegito saw the pure, murderous rage on the face of one of the most powerful fighters of the universe and found himself unafraid. In fact, he smiled.

"What's wrong? Has your confidence finally dropped?" Vegito grinned, his fused voice oozing with cockyness and gloating satisfaction.

Buu only stared, growling to himself, mind overflowing with plans for how to annihilate his enemy and make him suffer as much as he possibly could while doing so.

"It's not much fun being hunted down, is it Majin Buu?" That cocky arrogance began to drain from Vegito's voice as it was replaced with righteous conviction, "Being hunted down just like you hunted down our friends, does it hurt?!"

Even more anger flared up inside the pink monster as he heard the hero's words. It was true, all of it. Until the fused warrior showed up, Majin Buu was the undisputed king of this world, steamrolling every fighter he faced, being able to do whatever he pleased when they were not in his way. Now he was actually struggling, now he was actually feeling pain, and he absolutely hated it. There had to be some way to get revenge on the saiyan, some way to make him hurt worse.

"CURSE YOU!" Buu screamed in rage as he started to pull himself off of Vegito's ki sword, his pink, amorphous flesh melting and pulling apart like bubble gum as the searing energy of the saiyan's attack passed through it. Finally, after what seemed like an agonizing eternity to the villain, Majin Buu pulled himself completely from the beam, the damage to his clothes and his body slowly healing thanks to his regenerative powers.

Buu stared down his enemy, trying to think of a way to destroy him. His growing frustration suddenly started to plummet as he managed to think of a way to get the upper hand on his opponent, and a vicious grin spread across his face.

The space between the two fighters was quiet for a moment as Buu finished healing, Vegito letting his kids sword fade from his hand now that Buu was free of it. The pink monster gazed over the saiyan's body, blue and orange clothes draped over a trim but muscular body. Buu licked his lips as he thought of his plan, though it relied on an attack he hadn't used much at all, especially against an opponent this powerful, he knew that if it worked he would be able to do much more than kill this nuisance. He would be able to turn those muscles against the saiyan, not to mention have him at his complete and utter mercy.

The thought of finally turning this fight around, of being able to have such total dominance of such a strong fighter in one swift move made Buu quiver with excitement... even more so than he expected. Buu grinned even wider as his pants grew tight: He was going to enjoy this.

But then that stupid cocky grin appeared on Vegito's face again, and as it returned so did Buu's fury. He clenched his fists, shaking them with rage as he growled viciously at the saiyan warrior, "I warned you..." He seethed, "I warned you not to make me mad!"

Vegito's smug smile quickly turned into a confused frown as he heard Buu's growling become a roar. By the time the pink monster was starting to stretch, his amorphous body elongating and flying into the air, the roar had become an unearthly and ear-splitting scream. As Majin Buu flew he continued to liquify and stretch, now resembling a ribbon more than his normal humanoid shape. As the now snake snakelike form of the villain twirled and looped high in the sky, Vegito couldn't help but gape in astonishment, the spectacle a bizarre mix of gratefulness and horror.

"That's it you filthy pig..." Buu thought as a vicious, freakish grin split his elongated and distorted face, the ribbon of pink slime suddenly changing course to fly towards the astonished saiyan, "Open wide and swallow it ALL up!"

Vegito continued to stare and gape as Buu began to fly at him, unable to comprehend what the monster was doing. By the time he had realized that Buu was rocketing towards his open mouth it was far too late.

The tip of Majin Buu's head forced itself between Vegito's lips, forcing them to part wider and wider around Buu's thickening sludge. Vegito's jaw was locked in place now, held open as wide as it could go by the forceful torrent of Buu slime that was invading his body. The villain's shrieking howls died down as he forced himself down Vegito's throat, the helpless saiyan shiverring in disgust as he felt the gooey, heavy mass begin to fill his stomach. All the fusion could do was stand there as Buu poured himself inside, his body shaking from shock as he felt his belly filling more and more, growing tighter and tighter.

Soon the discomfort in his gut began to spread to other places inside his body as well as the liquified body of Majin Buu infiltrated every last inch of him. The warrior's back muscles began to tremble, then bulge, and finally bloat outwards as they inflated and filled with goo, rippling and bulging against one another as they competed for space. His arms followed suit, once thin limbs swelling horrifically with muscle in mere seconds until they thickened to the size of treetrunks. His legs similarly filled out as well, their transformation barely hidden by the saiyan's blue cloth pants.

Once loosely-fitting, his clothes now clung to his body, revealing the hideously massive muscles beneath as they stretched his clothes out. Vegito's pecs surged against his top, a sort of cleavage visible above his orange undershirt as thick nipples pushed visibly underneath both layers of fabric. The saiyan's backside quivered and shook as his glutes bloated massively, while on the opposite side the crotch of his pants tightened more and more to reveal the bulge that was growing with every gulp of Buu.

By the time the last of the pink ooze was snaking it's way into Vegito's mouth, the saiyan had become enormous. The male's body was almost a grotesque parody of its former self, muscles so freakishly bloated that they looked as though they had to compete for space on his overengorged body. As the tail end of Buu's liquified form wriggled past Vegito's lips with a slurp, the huge warrior let out a gasp, finally allowed to catch his breath.

Buu chuckled darkly to himself as he settled within his new host. His attack was a complete success so far, but this was only the beginning. He intended to make the fusion pay for making him look like a joke, and as Vegito looked over his monstrously massive muscles, he began to wonder just how he was going to get out of this...
