Orgasm on command.

"I'm just going to give you a special feature," Kazuma replied. "Darkness already has her pain and pleasure build up one, but I think with you, I can go with a much quicker form of pleasure... With a nice follow up too." With that, he started to write, "Whenever Kazuma Sato snaps his fingers and says, "Kaboom" to Megumin, she will immediately have an intense orgasm, regardless of her current stimulation level. However, instead of satisfying her, every time she orgasms this way, she will be left very horny and fully reenergized for some more fun."

Megumin watched him curiously, and asked, "So... What did you write?"

He simply grinned as he looked up. "Let's show you, shall we?" He snapped his fingers. "Kaboom."

Her eyes immediately widened and rolled up as she spasmed. "Mmmm! Oh god, oh god, what is this?" she cried out as she bucked her hips on air, her pussy twitching. After half a minute, she relaxed, and panted a bit, before looking at Kazuma lustfully. "Holy crap... That was awesome! Do it again!" she requested, horny from it as written.

"Okay," he smirked, repeating it, and watching as she again squirmed from the instant orgasm.

"Wow, that's so hot... You got her completely helpless under all that pleasure!" Darkness giggled.

Megumin recovered again, and gave Kazuma another look brimming with lust... "I'm still not satisfied," she noted, fingering her own pussy.

"It's not supposed to. It's a orgasm meant to prime you for so much more fun," Kazuma replied as she stripped himself down.
