Oolong did not seem happy to have joined Goku and Bulma's little adventure. Frankly Bulma didn't like it either, both because Oolong was most definitely a pervert, and shamelessly so, and because his presence meant that she and Goku had to be discreet about their fun, where as before they could fuck like wild monkeys when and wherever they chose.
Goku's skill with his tongue had only gotten better with practice, and he had been learning many new tricks thanks to his fun with Bulma. But Oolong being there ruined it, and now they could only be alone and have fun together at night when they could sneak away from the shapeshifting pig.
Goku still didn't fully understand why exactly this was. He asked Bulma a few times why they didn't just tell Oolong about their fun, maybe he could even join them for it, but Bulma seemed repulsed by the idea. Goku didn't see why, but then again, Bulma had needed to explain the difference between boys and girls to him, as well as how exactly he was different from other boys, so Bulma didn't exactly trust his judgement on stuff like this.
Eventually though, Goku decided to ask Oolong about something else he had been confused about. Bulma was away at the time, scouting ahead to try and get supplies from the nearest town while Oolong and Goku guarded little house she'd set up with her Dinacap.
"Oolong," Goku asked, "Why exactly did you want to take away all the girls from that town?" "You really need to ask?" Oolong questioned, though after a few days with the kid, Oolong wasn't too surprised. Goku nodded, "Should I know already?"
"Well Goku, most guys want girls around for when they get certain needs, you'll probably figure that out if and when you ever get to that age." Oolong chuckled. Goku tilted his head, "What, you mean like sex?" He questioned, having learned the word already from Bulma. Oolong's jaw dropped, "Wait, so you do already know about that?"
Goku nodded, "Yeah, it's what me and Bulma always do. Not so much since you joined us though, she doesn't like you being around when we do it." Goku shrugged as Oolong began to question all reality around him.
'How the hell did this kid get someone like Bulma in the sack?' Oolong questioned, though the realization that Goku, unintelligible as he was, might be confusing words and saying the wrong thing. Maybe he didn't actually mean they were having sex, and Oolong was just misunderstanding.
"So, when you say sex, you mean that you, you know.." Oolong did his best to describe sex, as he understood it, to Goku. goku shook his head, Oolong sighing in relief, figuring that Goku had confused the word sex for something else. "So what is it that you and Bulma do?" He asked, wondering what else Bulma and Goku could only do when he wasn't around.
"Usually we just use our tongue to lick each other here," Goku said, pointing between his legs, "But Bulma bought a few of these weird toys to take it even more fun." Oolong paused, staring at the boy. He couldn't still be misunderstanding, could he?
"So wait, you mean to tell me you've got Bulma sucking you off?!" Oolong questioned. Again, Goku shook his head, though now he was starting to think Oolong was the dumb one, and lowered his pants to demonstrate as he explained, "No, there's nothing for her to suck. She licks."
Oolong's eyes widened at the sight and the realization that Goku was a cunt boy. Suddenly the last few minutes, and the last few days, made a lot more sense to him. "You..you and Bulma.." was all he managed to get out, Goku nodding, "All the time. She doesn't want you to join though, she said no when I asked."
"You..wanted me to join?" Oolong asked, Goku nodded, "Sure, I thought I'd be fun, but Bulma said no." Oolong was quiet for a moment before saying, "Well...Bulma isn't here now is she?"
Oolong hadn't gotten off in way too long, and by this point he was desperate. Here was a C-boy practically offering himself up to him, how was Oolong supposed to refuse? 'Besides, it isn't gay, he's a C-boy', he rationalized to himself, willfully disregarding the fact that cunt boys were still male.
Goku smiled, "You wanna?" He asked, seemingly excited. Oolong nodded, "But it'll probably be different with me than with Bulma." Goku nodded, "I know, Bulma showed me how guys do it with her toys." Goku removed his pants and laid down on his back.
Oolong frantically removed his own pants, getting between Goku's legs and lining up his rapidly stiffening member to Goku's pussy. He gripped the boy's hips, and Goku looked surprised at Oolong's member, "Woah, it's bigger than Bulma's toy."
Bulma, not wanting to hurt Goku, had only ever used a four incher on him, so Oolong's six inches seemed decently huge to him. With the nice little ego boost fueling him, Oolong thrust forward, gasping out at how tight Goku was.
Goku moaned, his tail wrapping around Oolong's waist as they both began to move their hips, Oolong thrusting into Goku steadily as he fought off the climax that had nearly taken him the moment he'd thrust in. he'd gone awhile with no fun, and Goku's willingness made it even better than the girl's he had stolen away before.
"C-could you go faster Oolong?" Goku asked, Oolong not needing to be told twice as he picked up the pace, jumping harder and faster into him, Goku moaned as his pussy was stretched out to accommodate Oolong's member.
They only lasted a few minutes though, both cumming shortly after they reached the ten minute mark, Goku cried out louder though at the feeling of Oolong's cum pumping into him, an unfamiliar and oddly pleasing feeling that made him twice as glad he'd done this.
Oolong pulled out, panting gently. He began to moan again when Goku shifted around and licked his tip, "Bulma always tells me to clean off the toy when she's done using it on me," Goku said, thinking that the same rule applied here. He pushed his head forward, taking Oolong's member into his mouth and sucking on it sloppily, his tongue swirling around Oolong's length as he bobbed his head down it.
Oolong came shortly after Goku reached the base, groaning as he grabbed the boy's head and unloaded hot seed into his mouth and throat. "Fuck that was good~" Oolong groaned, unaware that Bulma was behind him, preparing to swing the butt of her gun down onto his head, as she assumed he was taking advantage of Goku.
