Gee...I would like to see this in English translated form if I can't do alone...
So I tried to translate the first six pages using google translator. I don't speak Japanese, so I just copied the symbols by hand and I hope I got them right. Also, as elee pointed out, quite a few of them are covered or really hard to see. If that happened, I added ***.
Anyway, here they are:
Page 1:
Big letters on the left: "The best moment. Supreme pleasure"
Page 2:
Letters on the right: "A shocking shot! Is Kimura's intention true?"
Speech balloon on the left: "Stand up in front of a mirror ***"
Letters on the wall: "Kimura Gym"
Page 3:
Upper balloon: "Seeing your figure."
Lower balloon: "The traps. The pecs (I'm guessing here, could also be some other muscle) and other muscles are one. Your body is an exquisite show. (This is a bit vague since I'm missing two kanji in the middle.)
Page 4:
Upper panel, right balloon: "This body. It's so hard."
left balloon: "I'm just an ordinary girl that wants to be normal."
Middle row, right balloon: (He says "Stew", but I guess it is meant to say "Bullshit.")
left balloon: "Touch it with your hands!"
Lower row: "How can you not feel it?"
Page 5:
Upper row: I can't make that out.
Middle row: "*** I breathe through my exhausted skin."
Lower row: "Careful ... It's beautiful."
Page 6:
Top row: "Mizukoshi Eri, you are the chosen one!"
Lower row: "I want this person who is watching me, but this body is mine."
"I am beautiful in this place ***"
Maybe I'll try some more later.
