Gisou Kekkon - Honban H Nante Kiitenai!

It's a fake engagement.. or at least it should have been! I never thought I'd actually have to have sex! But he takes care of all the most private corners of my amateur body, and makes me cum over and over!! So I can refuse the arranged marriage offer my parents gave me, I asked my secretary to act like my fiance. But then, he said: "We're engaged, so having sex is the obvious thing to do, right?" and he started coming after my body!!.
