Thank you again and sorry for the late reply! Fixing the typos is a no-brainer, but here's what I think of the other things you mentioned.
A.And it was inevitable. I cum. I just cum unsightly.
B.And it was inevitable. I came.
I came so shamefully.
A.I get horny right away and tonight too, (context?)
B.As expected, he's way more skilled now
since it's his second time doing this.
I get horny right away and, tonight too,
when Ike-san milks me with his whole body,
I orgasm while spilling milk out
A.[Cow]
B.[cow] *If that's what you meant, neither has heard a cow before and the [] are there to empathize the word.
A.spilled out his grudges(?)
B.spilled out his... grudges? *It was like A in Japanese, she's just stating what he did while questioning if what he did was just because of his grudges towards her. B works(?) too.
A.Being roughly fucked from behind feels
especially "I'm being used like an object"
and it's so amazing.
B.Being roughly fucked from behind feels
particularly "I'm being used like an object"
and it makes me so ecstatic.
C.Being roughly fucked from behind feels
like I'm being used like as an object and
it's so amazing.
D.Being roughly fucked from behind makes me
feel like I'm being used like an object and
it makes me so ecstatic. *I like D the most but, if you think it's terrible then feel free to let me know!
A.beat the cock...
B.beat the cock... *It's a meme/joke. There's just this joke of saying "can't beat the cock" since it's a saying, staple in Japanese adult games/doujins, when girls just can't win against it resulting them or other people saying that "Yup, no one can beat the cock" or "I couldn't beat the cock..." or "I couldn't win against the cock..." and so on. In Japanese he does say "she can't even beat cock", but there's no plural for it so it's either "can't even beat a cock" or "can't even beat cocks" and it uses the specific phrase that's used for "can't beat the cock" so I decided to go with that. If you still think it's silly/wrong then I guess I could change it.
If I missed anything please let me know and I'll reply back!
Congrats on finishing the game and I'm glad to hear you enjoyed it! Yeah, when I saw the game the first time I fell in love with the art style instantly. I just HAD TO make this the first game I publish. Thank you and I hope everyone will enjoy it as much as you did! Thank you very much for all the help again, feel free to ask me if there's anything on your mind, cheers!
