恥じ真理

剧情简介

Me and my little sister Mari talked about things together, even very secret things.

I was still surprised when she brought up sex.

What happened, little sister?
Of course she's at that age.
But, to ask me... me!? For advice? What should I do?

"Just let me do it with you," she said with a bashful face. "Teach me the real thing!"

Mari was being so forceful.
It was so unlike her. I was so turned on.
