My Introvert Boyfriend Wants to Please Me

My boyfriend, who moved to Tokyo as he got into my university, looks handsome but extremely "introverted."

He can't order coffee alone or talk to my friends properly.

However, he only talks a lot with me so I can't get enough of this feeling of being special!
There's no need to worry about being cheated on. Long live introverts!

But the masochist within me hopes that... he would dominate me during sex.
One day, my boyfriend found out about my inner desires.
I thought he'd get creeped out, but...

"Would you like to try it?"
"S-Suck it! How about that?"

At first, he teased me while blushing and looking somewhat embarrassed.
But gradually, the dark flame within his eyes grew more passionate.
His hidden sadistic tendencies slowly blossomed.

Even though usually he's so gentle and shy that he can't even enter a café by himself, the more times we did it, the more he satisfied my preferences...
