I really think this is MTL since you didn't TL any of the floating text or SFX but I could be wrong who knows.

pg 3.

I wish Seia-san is also here but she still recovering > I wish Seia-san was here as well but she's still recovering.

Sensei? What happen with you down here? > Sensei? What happened to you down here/ Sensei? What's happening with you down here?

Nothing, It's just I can see Mika's chest and armpit just now > Nothing, it's just I saw Mika's chest and armpits just now

pg 8.

I will make you feel good as much as you want. > I'll make you feel as good as you want (this sentence still sucks but at least it's grammatically correct now)

pg. 16

When Sensei spoil me like this. > When Sensei spoils me like this...

I want to do something back for Sensei... > I want to give something back for Sensei.../It makes me want to do something for him...

Sensei should also feels good as me > Sensei should also feel as good as me/as I am

pg 18.

Sensei, does my pussy make you feels good? > Sensei, does my pussy make you feel good?

pg 22.

Mika, it's enough... > Mika, that's enough...

pg 24.

Consider the poor typesetting and the occasionally weird wording, it's safe to assume that OP has done this book an injustice.

It's just that neither language are actually my first language. So I'm pretty much still learning both english and japanese but that's really nice of you to correct it. Regarding the floating text and SFX, this is my first stuff so I'm not on that level yet to clean them up all by myself.

@Zenith801

I think this goes without saying but, if you're not proficient in both the language you're translating into and the language you're translating from, you should not be translating.
