Reason

"Have you completely lost your mind!?" exclaimed Bulma, digging into her still-sensitive crotch and trying to scoop out Vahn's semen as she whined, "I know I said to take responsibility, but that wasn't an invitation to blow your load inside me, you dolt! What if I get pregnant!? I'm way too young and beautiful to get saddled with a kid...!"

Shaking his head, Vahn pulled out a warm, moist towel and calmly stated, "I understand why you might be anxious, but it's fine. Even if we did it a thousand times, there's no risk of you getting pregnant unexpectedly. And besides, your panic aside, it felt really good, right...?"

"I mean...you're not wrong..." conceded Bulma, accepting the towel with a look of confusion and intrigue, using it to dab and gently wipe herself as she unhesitantly questioned, "So, what, you're sterile or something? If so, that sucks for the gene pool. I bet any babies you made would grow up to be cuties or hotties themselves."

After waiting several seconds and realizing that Bulma had no intention of cleaning him, Vahn reluctantly placed his dick away, doing his best not to grimace as he shook his head and explained, "It's more like a unique trait of my existence. Unless I choose to impregnate a girl and she wants to be impregnated, my semen will evaporate and disappear at the atomic level within twenty-four hours. I know it sounds outlandish, but you're welcome to have it tested in a lab. In the meantime, if we're going to continue this, I'm not going to use a condom, and I am going to cum inside you. It feels better for both of us."

"You're a lot pushier than I expected you to be..." muttered Bulma, not for one second believing Vahn's story regarding his disappearing semen. She did, however, have a ring of birth control pills on hand, so she would allow him to have his fun—at least for the time being.

Shrugging, Vahn argued, "You haven't exactly been behaving reasonably yourself. If I were a bad person or someone targetting you for your family and its riches, you'd be in a precarious position right now."

"As if...!" exclaimed Bulma, tossing the used towel at Vahn's face only for him to effortlessly evade it as she asserted, "I happen to be an excellent judge of character. After all, I've spent the past eighteen years being the target of unscrupulous old men and opportunistic boys who only viewed me as a shortcut to my father's bank account. You're too calm, and you're dressed way too well to have money as a concern."

"Fair enough," conceded Vahn, stoking Bulma's intrigue a second time as he extended his right hand, producing a pair of simple white panties as he felt it was too soon to gift her lace or a thong. Not because they wouldn't suit her, but because the panties she had been wearing before were very simple—cute even.

"Alright, how do you keep producing items out of thin air? Are you some kind of Magician...?" asked Bulma, turning around and taking a moment to don the soft, warm, and surprisingly comfortable cotton panties Vahn had presented her.

"Kind of," responded Vahn, revealing, "I can't use complex Magic, but I can fire off beams and such. I'll tell you more if we decide that whatever this is between us is long-term. Because I don't need a sugar mama, and as deserving as you are of all a person's love and affection, you can't be the most important person to me."

"Well, obviously," retorted Bulma, rolling her eyes and crossing her arms as she added, "As for what this is, it's as I said before. I just need you to help me stick it to the girls back at West City for a few months, and then you and your girlfriend can fly off back to wherever you came from. Truth be told, I spend most of my time in my lab and workshop, so I don't have time to play the doting girlfriend. You're my trophy boyfriend."

"Alright, then, what now...?" asked Vahn, adopting a relaxed smile that caused Bulma's brain to stall temporarily, sporting a dazed look before she averted her eyes, blushed, and meekly responded, "I guess we go look for Goku and your girlfriend. It's actually strange that they haven't caught up to us..."

"That's because I asked Grayfia to look after Goku and wait for us to return," revealed Vahn, approaching and taking advantage of Bulma's turned back to caress her warm and pillowy bottom, his middle finger caressing her slit as he lowered his voice to a growl and asked, "Now, do you want me to carry you back, or do I get to walk behind you and enjoy the view?"

"My legs are still weak thanks to a certain someone, so you have to carry me..." responded Bulma, her face flushing as she closed her eyes, a faint moan rising from her throat as she marveled at how much better it felt to have someone else touch her...

"Alright, then..." hummed Vahn, surprising Bulma quite a bit as, instead of picking her up in a bridal carry, he picked her up by her sides, compelling her to ask, "What are you doing?"

"Wrap your legs around me," said Vahn, explaining, "I'm going to carry you like a baby koala. That way, you get to hug me and kiss my face and neck while I get to caress your butt. Everyone wins."

"Okay...I get that..." responded Bulma, her face flushing bright as she did as she was told, wrapping her legs around Vahn as she muttered, "But it's kind of embarrassing..."

"Mhmm..." responded Vahn, supporting Bulma's butt with his left hand and forearm while using his right to draw her into embracing him, his voice low as he stroked her back and playfully reminded, "You gave me a glimpse of your cleavage and flashed me your panties within two minutes of our very first meeting...you can live with a bit of embarrassment..."

"Haha...real funny..." responded Bulma, sounding annoyed but still burying her face between Vahn's neck and shoulder, nuzzling and kissing him with her eyes closed tight when she felt them leaving the ground. The thought that Vahn could drop her, consigning her to fall to her death whenever he pleased, immediately popped into her head, but she quickly calmed down when he held her tightly and reassuringly whispered, "You're alright...I've got you..."

"Welcome back," said Grayfia, sporting a slightly narrow-eyed smile and standing with her hands folded neatly atop her lap as Goku sat nearby at a table, feasting on enough food to feed five people.

"Did you miss me...?" Vahn asked, giving Bulma's bottom a light smack as she initially refused to let him go.

"Alright, alright, I'm getting down..." grumbled Bulma, loosening her hold on Vahn's body as he guided her to her feet. Then, while fixing her skirt, she looked past Grayfia at where Goku was seated, her head tilted as she asked, "Goku? Where did you get all that food...?"

"Miss Grayfia gave it to me~!" responded Goku, happily exclaiming with food in his mouth as he subsequently asserted, "She's way more of a girl than you are, Bulma!"

"Says the boy who's only ever met two girls in his entire life..." retorted Bulma, crossing her arms and meeting Grayfia's gaze for the second time. She thought of putting her foot down and asserting that Vahn was hers, at least for the time being, but when she met the silver-haired woman's equally silver eyes and calmly smiling gaze, she felt something she didn't quite understand. It was difficult to explain, but she got the same feeling from Grayfia as she might while standing near an exposed, high-voltage, exceedingly lethal wire...

Easing the growing tensions, Vahn asked, "So, what now...?" in a casual, easy-going tone.

Tearing her gaze away from Grayfia and staring back at Vahn, Bulma immediately felt more relaxed, the tension in her body relaxing and a smile adorning her face as she answered, "Well, no matter what, I still want to try and collect the Dragon Balls. If they function as the legends and stories claim, it would be super bad if they fell into the wrong hands. The vault in my lab is a heck of a lot safer than some musty old tomb or ruin that any random joe-shmoe can stumble across."

"Then Grayfia and I will serve as your and Goku's temporary guardians," said Vahn, appending, "We can make the journey a lot more comfortable, but unless the situation becomes dire, we won't intervene."

"Then I guess it would be too much to ask you to fly me to the location of each Dragon Ball?" asked Bulma, exhaling faintly from her nose.

"Adventures are good for the soul," responded Vahn, his smile gaining a hint of mischievousness as he supplied a playful wink and added, "Let's enjoy our time together, slowly and leisurely."

Developing a prominent blush, Bulma averted her gaze from Vahn's and muttered, "Well, we can't all fit on my bike...so I guess we'll need to use something like this?"

Pulling out her case of DynoCapsules, Bulma tossed one of the smaller ones onto the ground a short distance away, exploding into a white and yellow cloud that dissipated to reveal a four-seated blue convertible with a somewhat boxy design and the number 21 on the side.

Spreading her hands and shrugging, Bulma explained, "It's not really made for the rural countryside like this, but it beats walking. Though, I doubt you walk all that much—considering you can fly and all."

"We'll ride along with you and Goku," stated Vahn, nodding. The thought of leaving Bulma and Goku to their own devices and simply teleporting to them when they were in need briefly crossed his mind, but he also knew from experience how tension steadily compounded over time. Heck, even the thought of sitting next to Grayfia for hours on end, holding hands and relaxedly enjoying the scenery, both conscious of what they would do the moment they had the opportunity, filled him with a fluttery tension...

With the sun gradually setting, causing the sky to dim a prominent shade of pink and orange, Bulma, feeling annoyed after spending hours sneaking glances at Vahn and Grayfia through her rear-view mirror, brought the car to an abrupt stop in a large, stone-strewn clearing on the edge of a forest. There, she pulled out the largest capsule currently on her, flinging it a fair distance since the resultant explosion encompassed an area of more than ten meters in diameter, clearing to reveal an off-white, domed house with two smaller partial-domes on its flanks, one serving as a kitchen based on the chimney sticking out of it and the other a bedroom.

"It might be a little cramped for four people, but it beats sleeping outside or on the ground..." remarked Bulma, casting a sidelong glance at Grayfia as she added, "Unfortunately, the sole bed inside only has enough space for two people, tops."

Smiling in amusement, Grayfia looked to Vahn, prompting him to nod and say, "Do it," in a curt, authoritative tone.

Leaving Bulma slack-jawed and Goku floundering, Grayfia created a silver Magic Circle more than a hundred meters in diameter, first flattening and reinforcing the ground before producing a six-story villa that could easily accommodate dozens of people with ten guest rooms, a master bedroom, two kitchens, multiple bathrooms, a large bath, and a rec area with a fully stocked bar, two bowling lanes, and a small arcade.

"Just who the heck are you people...?" questioned Bulma, the sense of superiority she had over Grayfia, the result of being an unprecedented genius and the daughter of the wealthiest man on the planet, evaporating instantly. There were a few military-grade capsules that could be used to erect a small fortress in an instant, but the structure produced by Grayfia was both larger and far more luxurious, making it clear that she and Vahn weren't everyday common people...

"We can talk more inside..." said Vahn, taking the opportunity to cup and squeeze Bulma's butt, causing her somewhat blanched face to regain its color along with a hint of ruddiness...
