She had a bad feeling about this...
"Come here, come here~!" Roshi beckoned Bulma toward him. As Roshi looked at the girl who reluctantly stepped forward, it felt like another ounce of blood made its way to his groin. Kami, what an outfit~! Dressed in a black bunny outfit that perfectly accentuated her luscious figure, he couldn't help but leer at the cleavage of her ample chest, licking his lips. With each step, her knockers would bounce ever so slightly. Mai's seemed to be bigger due to her maturity, but these... they looked like they'd perfectly fill his hands. And they were so much bigger than Chi-Chi's! These were to be his compensation for putting out a measly fire? What a bargain!
"Wh- what is it?" Bulma asked, already dreading the answer. She tried to ignore his hungry gaze at her bosom. He wasn't exactly subtle... He is such a perv...
Despite the confidence he'd gained, Roshi was unable to utter his lewd request to the girl, beckoning Goku forward to tell Bulma of their deal in his stead. The young boy stepped forward and unabashedly pointed at her breasts. "Uhm... He wants to touch your chest."
"Eh?!" Bulma squealed, defiantly crossing her arms over her breasts. She knew it! She knew it couldn't be anything good with that old perv involved!
"If... If you don't let me touch your boobies, I won't put out the fire." Just like last time, Roshi had all the power. And like the blowjob last time, he would use that upper hand to get himself a good handful of Bulma's knockers.
Checkmate.
"Are you kidding me?!" Bulma yelled at him, advancing toward him until they were inches apart. With hatred filling her beautiful sapphire eyes, she grabbed his collar. "Why would I do something like that?!"
"But if I don't put out the fire, you can't get the Dragon Ball, right?"
Bulma looked at the old man with an intent to kill, but... she was forced to admit that he was right. Just like last time, she needed the old man to collect all Dragon Balls and make her wish. She gritted her teeth and instead began to look daggers at her monkey-tailed companion. Goku... you and your big mouth...!
"Hmmm... maybe I'll just go home now." It was the same trick Roshi had used the first time he persuaded Bulma. Well, if it ain't broke...
"F- fine!" Bulma once again agreed to one of the geezer's perverted requests. "However, I don't believe you can put out that fire, even if you are some legendary warrior. So I'll let you touch them only after you do it." It was partly true. In her scientific mind, there was no way an old man like him could put out that fire, but on the off chance that he could, she could buy herself some time to think up a plan to outsmart him.
"Okay!" Roshi agreed to the nubile teen's request. He put out his pinky, to make her swear on the sacred pinky promise. "Whoever breaks the promise swallows a thousand needles."
Bulma reluctantly tangled her pinky around his. He is so perverted!
With the deal finalized, the trio made their way back to the group with good news: Master Roshi would put out the fire!
"How about I put out the fire then?" Taking off his upper clothing, he revealed his lanky, frail body to the group. "Here I go!" He flexed his muscles – or lack thereof – and eyed Bulma with a grin. "Sexy, ain't I? "
"Yeah, yeah..." Bulma hesitantly played along. There was no way this old perv could put out a fire like that, she figured as she watched the old man gawkily climb one of the broken walls around the area for a higher ground. Just when he finally managed to find his footing, he almost slipped again. Bulma shook her head. There was no way he could do it. It seemed her chest was safe. Although... maybe just in case... her eyes rested on Oolong, a sly smile twirling her lips as an idea formed in her head.
With Roshi finally atop of the crumbled wall, he sighed. "Well, here goes." Taking a fighting stance, he gathered his energy and... "HAH!" In a trice, all of the old hermit's muscles engorged massively; shoulders, arms, pecs, stomach, legs... They all grew into boulders of steel!
The entire group was flabbergasted at the sight! Chi-Chi looked at the old man with admiration. So this was Master Roshi's true form! Even Bulma had to admit he looked impressive. Of course, the sudden growth of his muscles came with a prize. His trousers and underwear, made for his lanky legs and hips, were not able to contain the sudden increase in size, and before any of the group could close their eyes, they ripped apart to reveal Roshi's last muscle to the group. Ever since his eyes landed on Bulma, Roshi's prick had stood erect, and now his nine-inch cock was out in the open for all to see. Even with his entire body bulked up, it still looked massive.
Oolong cursed his luck and closed his eyes. Goku had little to no reaction, more shocked by the increase in the old man 's muscle mass than by his unveiling.
Bulma, however, couldn't help but eye the piece of meat with awe. It was without a doubt still the biggest she'd ever seen. Before she could help herself, she could recall the taste of his prick between her lips when she sucked him off for the Dragon Ball.
"Gyaa!" Chi-Chi shrieked as she saw a man's genitals for the first time. She tried to look away, but her sight was glued to the massive prick. It seemed so enormous. Were... were all penises so big? Her lips parted in awe, her eyes engorged, fascinated at the sight. Though she wanted to, she just couldn't look away!
Roshi, it seemed, either didn't care much for his sudden exposal or pretended not to mind, for he gathered his hands together, and began to utter, "Ka! Me! Ha! Me! Haa!" With his final "Haa!" he released a massive amount of blue energy from his hands, firing it straight at the castle. All bystanders were perplexed by the old man's incredible strength.
"Phew..." As the Kamehameha subsided, so did Master Roshi's buff state. All that remained was his lanky form, even his prick had withered into its soft state, though for how long was questionable. "Looks like the fire went out."
"Uhm... M- Master Roshi,'' The Ox-King began, "You... you put out the fire, but... T- the mountain and my castle..."
"I- it's all gone." Bulma screamed in astonishment. It had all been demolished! Just... just how strong was this old man? Even knowing about his hopeless perverseness, Bulma couldn't help but revere him, even if only a little.
"Looks like I got a bit too excited." Roshi hollered, laughing sheepishly. And speaking of excitement, the real exciting prospect was in hands reach, he thought, leering at Bulma behind his shades with carnal intent. Oh yes, the bunny girl was about to be his prize!
