Make Mika his.

"Did you enjoy that?" he asked her after rolling off of her.

"Yeah..." she panted.

"Would you want to do it some more?"

"...I wouldn't be opposed... So long as you didn't knock me up or get me sick or just didn't interfere with my life as a whole..." she admitted.

Touya nodded, and grabbed the Sex Note from under his pillow, and proceeded to write in it, "Mika will become completely obedient to Mochizuki Touya in matters of sex. She will become completely submissive to him and love following his orders. Any inhibitions she might have had will not apply to sex with Touya. This will only apply for sexual activities, including initiating them."

Touya then considered for a moment, and wrote, "Mochizuki Touya will lose his refractory period, and shortly after each ejaculation, will produce enough sperm to go another round until he himself decides to call it quits."

"What are you doing?" she asked him curiously.

"Oh, just writing in a magic notebook that allows me to initiate any kind of sexual scenario I want, within some limits."

"Oh? Is that what you did?" she asked as his first entry took hold, and she walked over to him, curious, but not upset, finding this whole situation immensely arousing.

"Yeah, do you regret it?" he smirked.

She considered for a moment, before shaking her head. "No... It feels too good, I don't want you to stop..."

"Good to hear," he smiled, taking her arm. "How about we go another round?"

She blushed, and nodded. "What would you like this time?" she asked, no longer feeling embarrassed, and realizing she was ready to do whatever he asked.
