She wants an upgrade.

"How about bigger boobs?" Megumin requested immediately.

"...I don't know... Putting melons like Darkness's on your slender body would just look weird..." Kazuma mused.

Megumin huffed. "Fine, then just make me go up a little bit!"

Kazuma considered, before saying, "Aqua, I wish Megumin's tits were as big as could reasonably be attractive to me on her."

"Just like a man to say that my breasts should meet their satisfaction. I suppose it was wrong of me to give you more credit," Megumin said as she noticed her breasts swell. They felt warm. But the heat ended a moment later which frustrated her. She looked at her breasts with a smile though. "I must say. For a perverted thief, your taste is acceptable."

"I'm an Adventurer, not a Thief class!" he grunted. "I just learned my first skills from a Thief!"

Megumin raised her eye at him. "Am I to assume your silence about pervert means you accept that part then?"

Aqua finishes one wine bottle and looks sad before she pops the top off the second one to top her glass off. "Master is quite the pervert isn't he. Hehe."

"...I look like a prude compared to... Well, that," he weakly gestured towards Darkness.

"The goddess of lust probably would blush if she saw Darkness," Megumin commented. "It's really not fair to compare anyone to her..."

Aqua put a finger to her lips. "Nah, they are about equals on this front I'd say," she said giggling.

"...what does the Goddess of Lust even look like?" Kazuma asked, not even bothering to hide his drooling as he let his imagination run wild.

Aqua smiled and placed a finger on Kazuma's shoulder. "You could find out! Just need to say the words!"

"I wish you had a picture of her right now!" Kazuma grinned, immediately taking her up on the offer.

A painting of the goddess appeared in Aqua's hands and she dropped the glass of wine. "Master! Why! Why pick the only boring way to see her? And why do it in a way I spilled the wine!" she set the picture down and sobbed.

"Like you don't have an unlimited supply, just clean it up," Kazuma rolled his eyes as he looked at the painting. "Besides, you were told a picture, not a whole ass painting. I also wasn't going to risk pissing off a Goddess by bringing her here on a whim!"

(I'll leave that particular Goddess's appearance to your guy's imagination. Any picture I could provide would probably just be disappointing compared to expectation anyway, XD.)

Aqua looked shocked as she grabbed a nearby rag. "You want me to clean it up the normal way!? Can't you just wish it clean!? Master! Why are you so mean to me?" She looked at Megumin who was checking herself out in the mirror and seemingly not paying attention. "...also, bullshit on the Goddess thing, you dragged me down to this world with you!"

"In my defense, you actively pissed me off before I did it," Kazuma replied. He then grinned. "Heh, I wish you had to wear a maid outfit as you clean," he smirked, wanting to both mess with her... and while he wouldn't admit it, he already understood that she enjoyed following his orders and granting his wishes, no matter how much she preferred otherwise. He was not above taking advantage of that.

"Master! That is not..." She snapped her fingers and the the outfit materialized. Her eyes rolled as she smiled and reached one hand down to her pussy to rub it. The other hand was rubbing the wine up. "I guess at least now if you do fuck me we get a bottle of wine out of it." She tried to act like that was what mattered.

"...I'm trying to decide whether to call you a jerk or a pervert that's giving her too much fun," Megumin noted to Kazuma.

"I think we both know you're just going to split the difference and call me both," Kazuma noted. Once Aqua finished, he told her, "Aqua, I want you to answer me honestly. Do you want me to fuck you like I did Darkness? Not even for the wine?"
