An explanation and then bed.

As Darkness recovered, Kazuma showed Megumin the Sex Note, and explained how it worked. How Darkness had gotten it first, used it on him, then gave it to him. "...so you used it on me then?" Megumin blushed. "...that explains all the spacing out..."

"Yeah, and what I did to Darkness was rob her of her sense of pleasure and pain temporarily. Instead of feeling it as it was given, it accumulated, and was released with a single finger snap," he replied.

"That's hot..." Megumin remarked, before pouting. "Did you have to prank me like that though?"

"Well, it resulted in you putting a lot of effort into it, and made Darkness cum pretty damn hard, so yes," Kazuma remarked.

"You're so good to me Master..." Darkness cooed half deliriously.

"...you have a point," Megumin admitted with a smile. "So... What will we do now?"

"I think we can head to bed now," Kazuma yawned, stretching. "It's been quite an eventful day..."

"Yes, yes it has been," Megumin nodded. They crawled into bed, and Darkness snuggled into his left side, Megumin into his right, and he wrapped an arm around both of them.

"Good night girls," he grinned.

"Goodnight Master!" they chorused, before all three of them drifted off to sleep.
