An Older Model: Chapter 3 (Goku x Bulma)

"Where are we going again?"

"We told you, Goku! It's a surprise! Now c'mon!"

Chuckling, the blindfolded Saiyan allows Videl and Erasa to continue pulling him down the hallway. And it is indeed him allowing it. While both women are now full-blooded Saiyans thanks to Videl's wish, and even as their pregnancies have progressed, they've been training heavily to increase their power levels, there's no denying that Goku remains magnitudes stronger than either of them.

In fact, at this point he prefers staying in Super Saiyan Four at all times, with his tail rejuvenated and swishing back and forth behind him. His power was… it was off the charts, but all that did was make Videl and Erasa hornier for him, truth be told.

If he didn't want to move, he wouldn't move, no matter how hard they tried. But luckily, he's come to accept that Videl can be a little… silly sometimes. Now, eight months into her pregnancy and six months into Erasa's, they're finally reaching the point where neither of them can exactly keep up with Goku sexually any longer. And given the beast they've awakened in the Saiyan, this is a problem.

Luckily, a situation had presented itself and so here they were, dragging Goku down a hallway deep within Capsule Corp's residential area, where both the Brief Family and a lot of their workers lived. Arriving in front of a very special door, Videl can't help but grin, being more than a little excited as she giggles girlishly.

"We're here, Goku… ready for your surprise?"

"Heh, ready as I'll ever be."

Now, to be fair, they'd already been staying at Capsule Corp, even before this… solution to their problem. When Bulma Brief had found out that her old friend Goku was not only living alone in the wilderness but had also gotten two young ladies in the family way, she'd browbeat the powerful Saiyan into coming to stay at Capsule Corp, where the scientists could make sure there weren't any issues with Videl and Erasa's transformations and pregnancies.

So far, so good on that front. Meanwhile, the sudden proximity had given Videl an idea. Having dinner with the Brief Family almost every night for the past few months had allowed Videl to hear no end of stories about Bulma and Goku's time together. More than that, she'd gotten to watch as Goku's mere presence pissed Vegeta off so much that the shorter Saiyan eventually ran off after a blowout fight with Bulma.

All of it had resulted in a perfect storm, so to speak. And now here they were, making something that one might argue should have happened two decades and some change ago, a reality.

Pulling Goku into the bedroom beyond, Videl nods to Erasa, who closes and locks the door behind them. Then, she looks to the woman on the bed… who smiles and nods as well. With everyone on board, Videl reaches up and pulls Goku's blindfold off… revealing to the powerful Saiyan Warrior that Bulma Brief is laid out on her bed before him, clad in sexy, slutty cutout-style lingerie that exposes both her nipples and her crotch.

"B-Bulma?!"

When Goku rears back in surprise, both Videl and Erasa are there to grab hold of him. Neither of them are capable of keeping him from fleeing, but with their advanced pregnancies, he has to immediately stop struggling or risk hurting them.

"Goku! This is your surprise. Bulma WANTS this… and I think, deep down, you want it too!"

Goku blinks slowly at that, even as over on the bed, total MILF that she still is, Bulma Brief smiles and nods, groping one of her breasts and spreading her pussy lips apart with her fingers as she gives Goku bedroom eyes.

"She's right, Goku. This has been a long time coming. All those years ago… I settled for Vegeta because I thought I couldn't have you. Chi-Chi had gotten to you first, or so I thought, and my chance was lost to me. But now… now I can finally get what I want. And what I want is you."

Goku's jaw hangs open, but he doesn't look upset at least, so Videl takes that as a good sign. The Saiyan woman licks her lips as she whispers in her mate's ear, her eyes never leaving Bulma's smoking hot body.

"Erasa and I can't handle your urges for the next few months while we're giving birth and recovering. But Bulma can, once you knock her up and turn her into a Saiyan too. She wants it, Goku. You know how smart she is. She's run all the tests and made sure that the science behind my wish is safe. Now… she wants in."

Slowly, Goku begins to pull away from them, but he's not trying to run, he's trying to step forward. And so Videl lets him go and Erasa follows her lead, the two heavily pregnant women watching as Goku approaches the bed, staring at Bulma's gorgeous body laid out on the bed for him like a ritualistic sacrifice or offering or something.

"Really?"

There aren't many people that can catch Son Goku off guard, these days. But if anyone could, it would be the girl he traveled with all those years ago… or rather, it would be the woman that girl grew up to be. Smiling, swallowing thickly, her eyes slightly watery with emotion, Bulma just nods, continuing to offer up her beautiful MILF body.

Videl can hardly wait to see what she'll look like as a Saiyan to as Goku hesitates at the foot of the bed, she calls out to her mate.

"Just fuck her already, old man! None of us are getting any younger!"

Her cat call causes Goku to let out a startled laugh, and a moment later he's on top of Bulma. Folding her legs up her body, sliding his cock right into her waiting, slippery cunt, he growls lustfully and primally as he begins to fuck her right then and there. Bulma doesn't even get another word out before most of her disappears underneath the powerful Saiyan male's broad-shouldered body and rippling back muscles.

Videl exchanges a glance with Erasa, biting her lower lip as her hands begin to wander. Bulma's cries soon fill the air as Goku begins to really fuck her, taking her in a consummate mating press. He's going for it, he's really going for it, and Videl knows that soon enough, they're going to have another pregnant Saiyan woman on their hands.

… They could rebuild the Saiyan race like this, couldn't they? But Videl isn't sure she wants to do that. Certainly, she's not going to be the one to bring up the possibility to her mate. She knows she has to share him… but not with a thousand women. Heh, maybe she should have made her wish a little different, maybe she should have thought of it a bit more.

As it is, what's done is done, and hindsight is twenty-twenty. With her and Erasa out of commission, the primal, sexual beast that Son Goku has become NEEDs a source of satisfaction. Videl can only smile as he receives that from Bulma, pounding her into the bed, causing her to squeal and cry out for 'More! More! More!', begging cutely beneath him.

From what Videl can see as she touches herself openly to the view, Bulma experiences several explosive orgasms at the end of Goku's cock. After more than twenty years of ignoring their feelings for one another, the two are finally together at least. They're finally joined as one, their bodies molding together, albeit Bulma's body giving way more to Goku's as the powerful Saiyan fucks a baby into the human woman.

Speaking of which, it's not long before Goku throws his head back and groans, slamming his hips forward one more time and filling Bulma's womb with his seed. Right before Videl and Erasa's eyes, the same change they both went through happens to Bulma. The blue-haired scientist groans and shudders as her body shifts and transforms, gaining a toned nature that it simply didn't have before, growing a bit more muscular as well.

She's got nothing on Goku of course, but then, none of them expect to suddenly be able to defeat their mate. Their Saiyan Physiology allows them to keep up with him in bed, that's all… and heck, sometimes not even that.

Indeed, as Goku pulls out of Bulma and off of her, sitting back on the bed with a heavy thud, the blue-haired MILF is left a panting, moaning, sweaty mess as her legs flop out and she just lays there for a moment, recovering. Soon though, she raises her head and makes eye contact with Videl.

"You understated how rough it would be."

Videl just shrugs, smirking easily.

"If you're too tired, Erasa and I can use our mouths to handle Goku the rest of the way, I suppose~"

Bulma scowls and then a moment later, a triumphant look spreads across her face.

"That won't be necessary. I brought back up, just in case."

With a snap of her fingers, a door on the other side of the room opens up and two women who had clearly been pleasuring themselves while eavesdropping step inside. Videl's eyes nearly bug out of her skull when she sees who it is. Bulma, she'd known about… however, she'd not been aware that Bulma intended on bringing Bikini Brief and Tights Brief in on it as well.

Bulma's mother and older sister are wearing the same sort of revealing cutout-style lingerie as Bulma herself, meaning their big breasts and fat nipples, as well as their glistening, sopping wet cunts, are all on display as they saunter forward, having eyes only for Goku who stares back at them, nonplussed… but clearly interested from his twitching cock.

Despite being a Grandmother, Bikini Brief is… well, she's a total GILF. Despite being a baseline human, her body has held up spectacularly after all these years, even as her husband has aged more and more. Meanwhile, Tights is just hot in the same way Bulma is, plain and simple.

Frowning ever so slightly, Goku runs a hand through the back of his hair, his attention mostly focused on Bikini.

"… Does Dr. Brief know about this?"

Beaming, doing that eye smile thing she always does, the blonde matriarch of the Brief Family clasps her hands in front of her and nods.

"He does, actually. Alas, he's getting older. He's come to accept that he can no longer take care of my needs."

Videl's mouth drops open, even as Goku nods seriously… and moves forward. In no time at all, he's making out with both of the additional Brief women, even as they rub their bodies against his, hugging into his sides. Bulma watches with a victorious smirk from the side as the trio end up taking to the floor in no time at all.

While Tights continues to kiss Goku, running her hands up and down his impeccable pecs and chiseled body, Bikini ends up on her hands and knees, soon taking the Saiyan male's cock from behind. Deep and hard, Goku fucks her, not having any of the nervousness that he showed with Bulma. After all, while he's known Bikini and Tights Brief for about as long as Bulma, he hasn't really gotten as close to them as he did Bulma.

Perhaps that's why its easier for him to just let loose and fuck a GILF like Bikini doggystyle until she's squealing at the top of her lungs for him to pump another baby into her, for him to make her a Saiyan and a mother all over again, for him to give Bulma and Tights another sibling. Or perhaps Goku is simply too aroused to hold back at this point, perhaps he's too turned on to be embarrassed.

Either way, the end result is the same. The powerfully built man fucks Bikini Brief into the ground and ultimately cums inside of her, turning Bulma's mother into a Saiyan Female right there on the spot as he knocks her up with his ultra-virile cum.

As he finishes inside of Bikini, Tights pulls away from him, the youngest Brief woman slipping from Goku's grip and giving him a grin as he looks to her next.

"Catch me if you can, you Big Saiyan Hunk~"

Her playful tone is accompanied by her darting back as he reaches for her with painstaking slowness. Amused by the sudden roughhousing, Goku keeps his strength and speed down to a bare minimum, chasing Tights around the room for a brief time as Videl, Erasa, and the girl's sister and mother all watch on.

Of course, it's not long before he ends up pinning her to the wall and taking her right then and there anyways. After all, Goku is still Goku and Tights… Tights wants to be caught. And so, she cries out and wraps her arms and legs around Goku's powerfully built form as he begins to fuck her, his cock spearing into her smoking hot core.

All four of the other women in the room, all of them now Saiyans with the enhanced senses that come with that, watch as their mate turns the fifth into one of them. Goku fucks Tights relentlessly, albeit with the same care he's shown all his human lovers. But then, as soon as he's cum inside of her and turned her into a Saiyan, her impregnation obvious when its followed immediately after by her transformation, Goku doesn't pull out of her.

Instead, he peels her back off the wall, spins her around, and lifts her into the air as he steps back towards the group. Almost like he's showing off to them all, he proceeds to fuck Tights far harder and harsher than before, now that she's a Saiyan who can handle more of his strength and power. Tights, for her part, cries out and cums her little brains out, her eyes rolling up in her head as her hands clutch at Goku's impossibly powerful arms, gripping his biceps the entire time.

Videl and Erasa can't do much beyond watch on, given how pregnant they both are. Their bodies are in the later stages of motherhood now, and soon they'll both have a child from Goku's loins to take care of and raise. Bulma and Bikini, however, are still more than capable of action. Crawling off of the bed and floor respectively, they both sway their hips over to Goku, mother and daughter moving in unison so they can press their new chiseled bodies into his sides.

As he finishes with Tights, the other two Brief ladies are already egging him on to fuck one of them again. The MILF and GILF Saiyan women seem to have just as much of a sexual appetite as Goku does, and they're no quiet about it.

Needless to say, the rest of the night is just as raucous and raunchy and filled with sex as the beginning. And even if Videl hadn't intended to bring in the entire female side of the Brief Family when she invited Bulma to join their burgeoning harem… she can't bring herself to regret even one bit of it. Not any of it.
