Sleep on it, then get a pleasant surprise in the morning.

"You know what, I think I'll decide on that in the morning," he decided. "Choosing to pursue a harem... That's not a decision to be taken lightly... And no using the Note to make me do it!" he added, seeing her thinking about it.

"Alright!" she nodded, her disappointment at that route being closed off drowned out by her happiness to receive an order to follow.

"Come into the bed with me, I'm too lazy to return to my own room right now," he added, getting up and stripping down to his underwear.

"Yes Master!" she agreed. They laid together in bed, and soon drifted off.

...

Kazuma moaned as he slowly came to in the morning. He blearily registered a pleasant sensation down in his crotch, and looked down to see Darkness had woken up ahead of him, and was currently bobbing her head up and down on his shaft, having pulled down his boxers. She looked up to see he was awake, and pulled off his dick, fondling his balls with one hand while stroking his shaft with the other. "Good morning Master," she smiled at him.

"Morning, slut," he grinned. "I don't believe I told you to do that."

"Do you want me to stop?" she asked, pausing and staring attentively.

"Now I didn't say that," he smirked, laying back. "I was just noting your excellent initiative." She grinned and licked along his shaft, before engulfing it once more. He continued to think as he laid back, enjoying the blowjob. Go for a harem, or stick with just Darkness?
