The tension eased between Bulma and Vegeta reasonably quickly. Enough for Vegeta to fuck his way back into sleeping in their bed again.

"What are you doing?" Vegeta had barely just finished making her come, when she grabbed her phone from the nightstand.

She opened up Pod, a CC owned dating app, "I wanted to show you some prospects." She said, patting the spot next to her at the top of the bed.

Right now? He hadn't even wiped her come off his chin. He resigned, lying next to her and taking her phone. She had over twenty new messages in her inbox.

"Who's Lingerie33?"

"That's me." She said.

"You're not 33."

"So?"

Vegeta scrolled through the messages, deleting them based on their looks, their profiles and how they had started their conversations. He narrowed it down to about three people.

"Okay, there's DoctorDaddy728. He's in the medical field and he has a decent profile." Vegeta explained, swiping though the guys images, "Also his first message was lame, but better than a simple 'hey'."

"What did he say?"

"Some crap about letting you see his PhD."

Bulma groaned and giggled into Vegeta's shoulder.

"Then there's Soya. 42, apparently a physical trainer, likes to hike and work out. Losing his hair."

"Hmm, yeah." Bulma smiled at the photos, "Maybe?"

"And then, there's Denim755. He's a model and younger." Vegeta said with a skeptical smile, "If he's a real person, that is."

"Oh, he's really pretty." She said, and then after a moment of pondering, "Okay, I'll message them all!"

Vegeta snorted and let her take her phone back. "You had any thoughts about what you want?" Bulma asked, her thumbs tapping away.

"Nope." He replied, looking up at the ceiling, "I told you my requirements. Maybe that gym rat will whip you into shape."

"Okay, but I don't want you to get jealous." Bulma said, and then her phone beeped. "Denim755 wants to get to know me." She announced with a giggle and then gasped, "He's only 2 years older than Gohan!"

Vegeta turned on his side to watch the exchange. "Sounds like a time waster. Ask for a selfie."

Goku pushed his turnip mash around his plate, listening to Gohan update his mother on his latest research project. Usually in these boring moments, he'd make faces at Pan across the table, or share an eye roll with an equally bored Videl, but something was on his mind.

Contrary to popular belief, Goku had complex thoughts and emotions. The traumatic brain injury hadn't made him a complet idiot, it only really altered his personality. He was smart enough to strategize in a fight, to be spontaneous, and to save the world a few times doing so.

Sure he loved the simple things in life - napping by the river with a fishing line set up, bathing in the tub, fighting someone... and his super fast metabolism made him appreciate food a bit too much.

He could tell when people made fun of him, too, or thought he was a simpleton. Sometimes, he even made jokes or tried to be sarcastic. Sometimes his quips fell flat. He loved a good pun. He loved playing with his kids and joking around with them.

Son Goku was not stupid, and sometimes he thought too much. Like right now.

Bulma wanted to open her marriage.

Normally, this was not the kind of thing he put much thought about. He was really surprised when Future Trunks told him that he was the child of his best friend and best rival. He couldn't imagine how it happened.

Did Vegeta get tricked into marrying Bulma?

It was something he got over. He wasn't even that mad about being forced into a relationship, once he got used to her company. In the end, he fell in love with her, and wanted children with her.

And they fucked. A lot.

It took Chi-Chi a while to work up the courage to ask for sex. At first she kind of... Posed awkwardly on the end of the bed hoping she'd ravish him, but Goku was too oblivious. She got titchy and frustrated and ended up yelling about him not doing his husbandly duties.

Nine months later Gohan was born.

It took them a while to courage to do it again, since Goku got it in his head that sex made babies. She eventually dragged him to a doctor and had them explain about contraceptives and safe sex.

Then they fucked. Constantly. Right up Gohan started kindergarten, and then, when he proved to be a genius, Chi-Chi had another passion, so the sex kind of waned to an eventual halt.

Then Radditz happened. Goku died and didn't come back for a year. And then he came back to fight Vegeta and Nappa, broke all his bones and went to Namek when he was better. He the trained on Yardrat for another two years, and came back, only to train for another three years. And he was told he was going to have heart problems.

During this time, Chi-Chi and Goku didn't really fuck. For one, Chi-Chi had barely seen him in 4 years, and was pissed off about the whole thing. The prospect of heart failure and the world possibly ending by androids want exactly a turn on. Needless to say, there was tension in the Son house.

Right before the Cell Games, Goku and Gohan, in Super Saiyan form, returned home for a week. One morning, Chi-Chi took the hover car out and came back with some interesting purchases, and kicked Gohan out. It seems that while Goku was absent from her life, she had spent some time reading, mostly trashy romance novels. Once she'd run out of those, Bulma hooked her up with some steamier ones and...

Well, let's just say Chi-Chi wasn't into vanilla any more. They had to keep giving Gohan errands to get him out of the house.

Of course, all good things must come to and end, and Goku died for another 7 years. Chi-Chi, convinced her husband was going to gone forever, voided the marriage. She don't move on, focusing on her raising her kids right instead. But she definitely thought about it, she told him one day, in a moment of vulnerability.

When he came back to fight Buu, and promised to stay, they quietly remarried, properly, with no tricks. They had four blissful years of sex and farm work.

Of course, Chi-Chi's body started getting older. With aches and pains, they found they weren't doing it as much as they were used to. Not in the traditional sense, anyways. She still tied him up.

And now, both of them pushing fifty and Goku still having the body and libido of a twenty year old, Bulma and Vegeta were opening their marriage.

While Goku didn't harbour romantic feelings towards either of his closest friends, he had to admit that they were both very attractive people and he would definitely do the sex with both of them. Vegeta even more so, because he was really strong and that was Goku's biggest turn on. He'd had to tuck his thing into his waistband many times during a fight, not just with Vegeta, but many of the people he'd fought. He supposed he fancied strong, muscular people. Moreso strong, muscular people who didn't want to destroy his home.

Only one other person knew about Goku's apparently bisexuality, and that was Krillin, years and years ago. His best friend joked about him getting turned on when he got excited about fighting and Goku didn't deny it.

"Wait, that's kind of... Y'know... gay." Krillin, still young and single (and bald) had once remarked.

"Huh? What's that?" Goku stopped doing his kata and looked over to his friend, who was resting.

"Gay. Liking guys. Or getting turned on by them."

Goku frowned. "Is 'gay' a bad thing?" He said, shrugging and starting the pattern again.

"Well, uh... No..." Krillin said, a bit uncomfortable, "But you've got a wife!"

"Yeah?"

Flustered, "Wait, so you like guys and girls?"

"...yeah?"

"I mean, get turned on by, not just friends."

Goku stopped again and thought about it. "I like... strength. I get... excited when I fight a strong person."

"Um? Like who?"

Goku thought about his last greatest fight, in the 23rd World Martial Arts Tournament. "Piccolo Jr." He said and smiled, thinking fondly about his new nemesis, excited to fight him again.

Krillin nearly fell off his rock, "But... He's not even human?"

"He's human shaped, if you ignore the ears and antennas." Goku said, the beginnings of a blush dusting his cheeks.

"Goku! You're married! You can't be thinking that!" Krillin said.

"What's wrong with thinking it? Chi-Chi can't read my mind... Even though it sometimes seems like it." Goku grinned, scratching under his hair, "It's not like I'm gonna... do anything. Plus everything's fine with Chi-Chi." More than fine. Excellent even.

Krillin stared at him with a mix of horror and heavy skepticism. "O-okay. Wow. Just found out my best friend likes guys." He muttered.

"Don't you like guys?" Goku went to join him by the rock.

"No!" Krillin practically shrieked, a little too quickly, "I don't like guys! I like women! With big titties!"

"Huh. Is it wrong for me to like guys?"

Krillin sighed, "No, Goku. I just... think you should keep it to yourself. You're married to a woman. And you're not supposed to like anyone else."

And so, he tried to repress his feelings.

And now Bulma wanted to open her marriage.

Would Vegeta let her? Did he want to-

"Goku, sweetie, you've heardly touched your turnip mash. Is everything okay?"

Goku snapped back to reality, realising everyone was looking at him now. Not to lose face, he started shovelling cold mash into his mouth. "Mm... Yum." He forced himself to say.

Chi-Chi stared at him. Goku was hardly ever put off his food. Something must be wrong.

After dinner, while Gohan, Videl and Goten did the dishes, Chi-Chi pulled Goku aside. "What's wrong? You're moping."

There was no point in lying. She'd whip the truth out of him if he did. "Hey, uh, I was gonna bring it up later tonight, when we were alone," He started, leaning in to whisper, "It's about Bulma and Vegeta."

Chi-Chi gasped, "They're not separating, are they?"

"No! Well, uh..." Goku looked around, and nodded towards the bedroom. Once they were out of earshot, Goku spilled the beans in practically one breath.

Chi-Chi was stunned. "Hold on, let me see if I get this right... They're not breaking up, but they're going to open their marriage? And it wasn't Vegeta's idea? Because I always thought he was kind of a delinquent-"

"Could we open our marriage too?" Goku asked, taking her hands in his and begging with his eyes.

Chi-Chi didn't think she could be more surprised. "What?" She stepped back a bit, "You wanna... What?"

You could do that?

She shook her head, "Are you saying you want to cheat on me?"

"No! I mean, you're... Well, you're human, and you're getting on a bit-"

Chi-Chi had flames in her eyes. She locked the door. "Bend over and pull your gi down." She demanded in a half-whisper.

This wasn't an unfamiliar threat. This was how they sorted disputes sometimes.

Goku was lightning quick, obeying his mistress in a split second, his bare ass on display.

"You think I'm getting too old for you, huh?" She said, grabbing her hairbrush, the first thing that she had on hand.

"No, ma'am." Goku said with a gulp, cursing himself for saying something so stupid. "I'm sorry, I didn't mean to, uh..." He trailed off as be felt the cool wood of the back of the brush smoothe over his cheeks. He forgot what he was going to say for a moment.

"Didn't mean to what?" Chi-Chi growled, and when he didn't answer a millisecond later, she hit his ass with a resounding THWACK!

Goku gasped, "Insinuate! I didn't mean to Insinuate you were weak!"

Chi-Chi stopped, "But?" She prompted him, reaching out and raking her nails over the red spot she'd made.

Goku's cock was filling out between his legs. "But... You've been too tired and sore to do sex or play with me. We've been doing stuff less and less."

Chi-Chi paused and then gave him one last smack for good luck. Goku whimpered and pulled up his gi pants when she put the brush on the bed, signalling the punishment was over. "Its true." Chi-Chi said, sounding sad, "And it's not fair on you." She sat next to him on the bed. "I'd love to be younger again, but I'm also fine with being older and getting on with life. I'm just sad that I'm getting older and you're staying the same."

"Aw, Chi-Chi..." Goku said, sitting with her, wincing at the mild pain, "You know I'll always love you. Maybe we could use the dragon balls to make you younger."

Tempting. "I don't know. I'm very attached to the idea of retiring in a few years." She confessed, taking his hand.

They stared into each other's eyes. They had a kind of secret language too, through soft looks. He squeezed her hand gently. Things were uncertain right now.

"I'll think about it." Chi-Chi said, patting his thigh and going to stand, "I'm going to go get dessert ready."

"Uh, Chi-Chi..." Goku started, and then indicated to the huge tent in his loose gi, "Can I take care of it?"

Chi-Chi looked down, and then back up, "Hmm... No. But maybe I'll fuck you later." She touched his face and then winked, confirming her promise.

"Aww... Okay." Goku pouted playfully, watching her go. Guess he had to really focus on getting rid of his boner so he could have dessert. But the promise of doing sex really excited him! And dessert!

This was gonna take a while.
