Hell yes.

"Can I get some help getting to the water actually?" Aqua asked cutely, flopping her tail for emphasis.

"Why? You can take human form at will, and the transformation should be smoother after the first time if Megumin and Darkness are any indication," Kazuma remarked, making both mentioned girls nod.

"I know, but I want to make my first time as a mermaid special," Aqua pouted.

"...fine, Darkness, yeet her in. Megumin, watch for alligators."

"Wait, yeEEEEEEET?" Aqua asked, before ending her sentence screaming comically as Darkness picked her up and threw her at the lake. SPLOOSH! Kazuma watched with some amusement as some bubbles came up from the water, and Ria was laughing herself sick at the entertainment value.

Kazuma stripped himself naked before wading back into the water as Aqua surfaced, giving him a pout. "Was that really necessary?" she asked.

"Not really, but it was amusing," he smirked, deepening her pout.

"You can be so mean Master," she huffed, crossing her arms, staying afloat with movements of her tail.

"Yeah? What else is new?" he quipped, before pulling her to him and giving her a kiss. She moaned, relaxing, and easily returning the kiss.
