Naive Girl "Mimidoshima" (lit.: ear year increase) refers to a girl or woman whose knowledge of sex is mostly theoretical, not first-hand. She has heard about things she hasn't experienced, hence "her ears are older than herself".

I'm an American! I've had as much sex as I wanted! You gasp "Oh yes, oh yes!", right!? Don't make fun of me because I don't speak English, okay!?

V-vibes!? L-let's see... I'll use thr-... five!!!! I guess I'm using five at once!

Rather than having sex while looking at a beautiful night view, I think having sex in a "Magic Mirror Number" better!! Err, uhm, normal people don't have sex in "Magic Mirror Numbers", you say? "マジックミラー号" or "MM号" (Magic Mirror gou, MM gou) are an invention by the Japanese AV production company Soft On Demand. It refers to a truck with one way mirrors, which can be seen through from the inside but not the outside. This allows the people inside to perform acts of pseudo-exhibitionism in a legal way. If it gets dark outside, curtains have to be drawn on the inside, as it becomes possible to see through the one way mirror.
