Film Introduction

My girlfriend, who lives with me, had to leave for a business trip out of town. Whether she knew my girlfriend was away or not, my younger sister Mitsuki showed up at our place. She's nothing like her; a total gal. Unable to resist the temptation of this little sister, I kept going all the way, to the point where I'm worried she might have gotten pregnant.
