Thrust in, but fuck slowly.

"...fuck it! Literally!" he finally thought, before thrusting all the way in with a single motion.

Darkness moaned, then she screamed in pleasure. "Master isn't even letting me hold him while he takes my first time. Like I am some inhuman fuck doll!" she yelled as she wiggled, her arms still behind her back, unable to move them from where Kazuma had ordered. She settled for wrapping her legs around his waist.

"...oh, that's right, I forgot about that," Kazuma chuckled, but didn't correct it, moaning as he began to fuck her slowly, pulling out, then thrusting back in.

"Ah! Master! Why did you slow down?!" Darkness squealed, bucking her hips into him.

He grunted a bit as he kept going. "I didn't, I'm just starting, and don't want to cum too soon," he smirked as he exercised all of his willpower to maintain his slow, teasing pace.

Darkness whimpered as her legs tightened around him. "You plan to make this suffering last even longer? Fine! Give it all you got! I am not so easily bested that I can't handle this much," she said as she leaned her head back and moaned again.

"Oh, you want me to up the stakes?" Kazuma asked, placing his hands on her boobs for stability as he continued to slowly pump into her. "...Aqua, I wish that whenever my dick is in Darkness, her tits become as sensitive as her vaginal walls, and her nipples as much as her clitoris..."

Aqua smirked as she snapped her fingers. "Done, yet another thing for-"

Darkness screamed at the top of her lungs as she pushed into hips into Kazuma. "Oh god, oh god, oh god!"

Her breathing became rapid as it became more like she was fucking Kazuma from underneath than him fucking her from up top. Her strength clear as she pushed his whole body up and down from her hips alone.

Aqua bit her lip. "Looks fun. She even interrupted me. How rude can you get," she said with a huff.

Kazuma was taken aback by Darkness's actions, but decided to speed up just a little bit, giving her breasts a squeeze, before leaning down to lick and suck on one of her nipples.

Darkness increased her pace as she continues to scream and moan in an increasingly breathless fashion..

"Okay Master. I'm sorry for... Oh, Eris. Master yes! Yes! I mean, please. I surrender. I surrender! Mercy! Mercy! I can't take anymore! I'm going.... oh God! Oh fuck me. Fuck me harder! Master please!"

Aqua giggled while watching. She was horny and slightly agitated. If she was expected to just watch quietly more in the future, she hoped that her master would have the decency to stock the shelves with wine or snacks. Or let her touch!

Kazuma gasped, beginning to pound into her, and lightly nibbled the nipple in her mouth as she arched her back, pressing the boob into his mouth.

Darkness felt Kazuma seed fill her insides. "I'm... I'm gonna orgasm!"

Kazuma leaned back and stopped groping Darkness's breasts. She collapsed onto her arms. "Seems I came first." He slowly pulled out of her, looking pleased with himself.

Darkness just laid limp. "Kazuma went inside. I'm holding his seed. I'm gonna get pregnant~. Hehehe..."

Kazuma stiffened, then looked at Aqua, concerned with the incompetent goddess's previous wish granting.

Aqua blinked, not getting Kazuma's look, before realization dawned. "Oi, you actually think I'd screw up such an important wish?" she demanded.

"...yes," Kazuma answered bluntly.

"Her brains are practically mush right now, you think she remembers that she can't get pregnant!?" she threw her hands up in exasperation.

"Supposedly," Kazuma snorted.

"I don't have to listen to this!" Aqua shouted as she tried to float off towards her room.
