Emiru, obviously!

[Author's note: I'm a different Author from the one who started this branch, and have chosen "Ken Aizawa" as the MC's canonical name to make things fit better.]

Your eyes widen in horror as the door swings open. At the entrance stands Emiru, her hair done up into a bun, dressed in nothing more than a bath towel around her torso. Time seems to freeze for a moment as your eyes take in her nearly naked form. Her doll like eyes. Her perfect skin. Her legs that run up to where the towel enticingly hides their origin.

Mrs. Fukada was right. Maybe you did have yellow fever.

"Um...Aizawa-san?" Emiru's voice cut through your fantasy, snapping you back to the real world, and the absolute hell you're about to enter.

"A-AHH! U-Um...E-Emiru-san! It's-It's not what it looks like!" As the words leave your mouth, you mentally facepalm. 'Not what it looks like'? What am I, in some sort of ecchi anime series?

As the two of you stare at each other, you come to realise Emiru hasn't reacted to your compromising position. You expected her to scream, or slam the door, or at the very least yell "PERVERT!", but nothing of the sort happens.

"So...uh, what are you doing here?" You awkwardly ask, trying to break the uncomfortable silence.

Emiru shifts slightly and averts her eyes. "Mother wanted me to help you with your bath...and your yellow fever."

'Yellow Fever'...that's the second time you've heard that, even though you have no idea what it means. The first was from Mrs. Fukada, and when she said it, she-

Your thoughts are cut short at what happens next. Emiru shuts the door behind her, then approaches you in the bath. It can't be more than two meters (Japanese are so space efficient!), but it's enough time for her to reach up to where her towel is, and with a simple tug, drops it in a single fluid motion.

Your jaw drops. You fight the urge to pinch yourself. Standing in front of you was Emiru Fukada, daughter of your hospitable host family in the land of your dreams (well, your weeb dreams anyway), in all of her naked glory. You've watched porn in the past, of course; many of them featuring various JAVs or other asian actresses, but the experience of seeing an actual naked girl in front of you, in the flesh, for your eyes only turns you on harder than any porn video you've seen up until now.

Emiru doesn't quite have the bust that her mother does, but they still looked like a nice handful that fit her petite frame. Combined with a taut stomach and smooth thighs leading to a cleanly shaven groin easily made her fit all the characteristics that you fantasized in your dream girl.

"Um...what would you like me to do, Aizawa-san?" Emiru spoke tentatively. You realise you were so distracted at taking in her looks that you didn't even notice that she was now kneeling at your feet. Was she...offering herself? Staring at her naked was one thing, but could you really take advantage of her like this?
