A fairly straight forward translation. As usual, I try to stick to the original story as much as my knowledge allows me.

Update 1: All pages are up now. I might rewrite it later or change fonts.

Note: There seems to be no real connection between the scenes, or just lazy work by the author.

for example:
1) On page 14 Servel asks if she can drop the honorifics (-kun in this case), but on the paizuri scene (page 16, she says it again.
2) Again, on page 14 and 16, the first 2 sentences are exactly the same (copy-paste by the author, might be the reason why the honorifics returns after page 14?)
3) After page 20, it seems like "Penis-kun" had run away, because Serval starts talking about "where did you go yesterday?". There's no clear indication in the CG about this.

I might when done make a few changes to make it more streamline

Penis-kun too OP.

So, his name is "Penis-Kun" and his animal type is a "Sex-Friend".
I'll be sure to ask for information about them at my local zoo.
