完璧生徒会長の秘密の性癖～高嶺の花の彼女をＭ女に開花させてやる～（Kanpeki Seitokaichou no Himitsu no Seiheki ~Takane no Hana no Kanojo o M-jo ni Kaika Saseteyaru~）

“I like you! Please go out with me!”

Standing right in front of him was Sorayume Sae, the student council president and the most beautiful girl in the school—so stunning that no amount of praise could do her justice.
Well, this is it. I’m done for, he thought… but to his surprise, she said yes!
And the very next day, they were off on a date to the amusement park!

(Sae’s my girlfriend now. So, of course, it’s only natural that we’d…!)

Drawn in by her mesmerizing lips, Hiromu leaned closer, his face inching toward hers.
But then…

“We’ve only just started dating, you know.
These kinds of things should happen after we’ve spent more time together, gotten to know each other better, and built a proper connection. So, let’s take it slow, okay?”

Or so she said, but somehow, they ended up at a hotel anyway…

“Listen, we’ve only been dating for one day.”
“Time doesn’t matter. It’s about how we feel, right?”
“W-well, yes, feelings are important. Fine, I’ll admit—even if it’s just one day after starting to date, physical intimacy can happen. But… but this?! What on earth is this supposed to be?!”

There was nothing strange about the situation.
Using a rope he found lying around, he’d tied up the beautiful girl, creating the most adorable and risqué sight he’d ever dreamed of.

“You’re tied up with rope, emphasizing your chest and other… important areas. It’s the perfect look. What’s wrong with it?”
“That’s the problem! Who in the world ties someone up with rope the moment they step into a hotel?!”

And so, the two of them continued on their… unique path.
