First page wasn't in the raw you sent me, but eh, whatever.
I've not retranslated all the bubbles, because most of them are pretty OK. I will do them if you ask me to, though. Also tell me if you want any sound effects.
Page 3, bubble 2: Do you… prefer them big?
(Reasoning: She does not directly refer to them.)
Page 6, bubble 2: I've always feared… that they might be too big… // Is my chest… to your liking…?
Page 7:
Whoah!
I've never really seen one before, but
this is clearly a big one… right‽
(Reasoning: “amari” here means, from what I can gather, that she knows what they're supposed to look like but hasn't seen any in person. I think “really” covers that quite nicely.)
Still, I can't show fear since I'm older…!
Oh… that's stunning. // Right!
Page 8:
How about… this?
This… is what they call a boob job, right?
Is that's how it's done??
Ah… Tsuruse-san, this—oh yessss
(“Yabai” is basically a moan here, methinks.)
Oh yeah, he likes it! // How cute! ♥
