She's jealous

"Not my fault that your body keep turning my cum inside you into water."

Kazuma: "Well you guys kept fucking with me, so I thought I would return the favour."
Aqua: "Am I not good enough?! Why do I have to be rejected by a virgin loser like you?! Huh??"
Kazuma: "I'm sorry. I lied about gender equality."

"Somebody please make a doujinshi that starts like that (fapfap)"
-A Doujin Artist

Megumin makes sense considering their relationship, Darkness as well due to Kazuma's inner nature, and I'll be surprise if Wiz, Chris, and Yunyun aren't around the corner. Kazuma may be attracted to Aqua's body, but she as a person is what keeps him from making a move.

Mistakes were made?

That would imply that Kazuma would be capable of tolerating Aqua's whining long enough to actually ejaculate inside of her.

While Darkness and Megumin aren't exactly models for potential mothers. There's no way in all of the underworlds, Aqua could pass for a mediocre mother.

Certainly not with her alcoholism and gambling for starters...

She's a goddess that actually cares for her followers. In the final episodes of the second season, Aqua show some nerve equivalent of a 'mama bear' usually has when her 'holy city' was in danger.

Either Aqua's only just then finding out that they're (more than six months) pregnant, or she's upset that Kazuma spent her booze money on Darkness' maternity armor.

That actually has some depressing implications if you dwell on it.
