Goku and Chichi had reached the Turtle Hermit's little island home. They had been hoping to get the Bango Fan to put out the fire engulfing the mountain where Chichi and her dad lived, but evidently Roshi had accidentally thrown the fan out, leaving them with something of a dilemma. Roshi could more than settle the issue himself, but the main hurdle in the way of that was that he couldn't be asked.
"Please Mr. Turtle hermit man, we need your help! My dad was your student, don't you care about us?" Chichi questioned desperately. Roshi nodded, "Of course I do, but if I'm gonna go all the way out there to deal with a problem you got yourselves into, I expect to get something in return, and I expect to get it before we go. You understand? Not sure what you expect to give though, that girl of yours was your best bargaining chip and you left her behind." Roshi chuckled in amusement at this.C
hichi didn't understand this, then Goku explained how Bulma has accidentally flashed Roshi, showing him her entire naked body instead of only showing him her panties like she had meant to. It had been her fault for not realizing really. Goku had been able to figure logically that Roshi wanted to fuck Bulma, but even that was only a guess on his part. Even with knowledge of sexual matters, the C-boy was still a few fighters short of a tournament in terms of the brains understood this though, and knew that she needed to do anything to get him to come over and help them. "W-what if we put on a little show for you here?" Chichi offered. Roshi raised an eyebrow, "What kinda show?" He questioned. "You know," Chichi said, reaching over so her hand ground against Goku's crotch, "A show~ you can watch us do it, then you can come help us out."
"Any why would I want to watch you two?" Roshi questioned. Chichi whispered to Goku, and they both nodded, dropping their bottoms and showing that they were a futa and cunt boy respectively. Roshi's jaw dropped as he saw this, and he couldn't help but get a little perverse excitement from the thought of watching the two of them fucking. "So, what do you say~?" Chichi asked with a smile, her bright red blush showing her embarrassment of the situation.
Roshi paused for a moment, then nodded. "Alright, but you had better make it good. If I'm not satisfied I'm staying put." Chichi nodded, smiling excitedly as she pulled Goku closed and kissed him. Goku kissed her back, the two starting to make out heatedly as Chichi's member started to get stiff. Chichi reached around Goku, smacking his ass before turning him around so Roshi could see his pussy as her member began to push inside of him slowly.
Roshi's member grew stiff in his shorts, and he figured that if they didn't mind putting on the show, they wouldn't mind him really enjoying it. He undid his pants and began to stroke himself to the sight as Goku and Chichi moved their hips together slowly, working Chichi's cock into him gently at first, until Chichi realized that Roshi might not want to see it slow and passionate, as much as Chichi wanted her first time with her future husband (she hadn't told them that they would be married, but she would later when he was ready) to be special, she figured there was nothing for it.
Chichi thrust harder into him, making Goku grunt at the sudden change in pace. He didn't mind, his tail curled around Chichi's waist affectionately to encourage her to keep going harder. She obliged, pulling Goku's hips down against her as she thrust up harder, forcing her cock deeper into his tight, wet cunt, making Goku moan louder with her as Roshi continued to jerk himself to the show, getting more into it as he watched. It might take him awhile to get going, but once he did, he was several dozens times better than a normal man, his member eleven inches long at full hardness without even using any ki to enhance himself.
He watched them continue to fuck, his lust building as he watched them, deciding that he needed a warm hole to get off on, his hand not providing enough pleasure, even with the viewing material. Chichi and Goku seemed to have forgotten they were putting on a show, Goku now on his fours with Chichi slamming her entire cock into his pussy as hard as she could with each thrust.
He moved over towards them, getting behind Chichi without her noticing him. He watched her hips pump hard into the money tailed C-boy, debating which hole to go for. She was undoubtable a virgin in both, but taking her pussy would cause too much alarm with her father, and lacked deniability when it came right down to it. 'Ass it is.' Roshi thought, lining his cock up to Chichi's virgin asshole.
Chichi screamed in surprise and pain when she felt Roshi's cock penetrate her ass, his enhanced strength letting him force several inches of his cock into her tight ass, making it stretch apart hard as the force of the thrust pushed her own cock deeper into Goku. Chichi came instantly, feeling like her ass was about to be ripped open as Roshi held her hips, drilling her ass, the movements causing her to continue railing Goku.
Goku didn't notice anything wrong, moaning and encouraging Chichi to keep going, taking her cum as she hit climax after climax from the overwhelming floods of pain and pleasure brought on by every thrust from Roshi into her poor abused asshole. Goku groaned, tensing up after Chichi's fourth orgasm, the constant filling of cum from her pushing him into his own finished off a few minutes later, letting out something like a growl as he unloaded a massive flood of burning hot seed deep into Chichi's ass, causing her to cum one last time into Goku's already overfull pussy. They all panted, Chichi practically unconscious by this point. But Roshi found this pretty decent payment.
