Okay so it's my first translation on Danbooru. I've been doing some doujinshi translation, but I'm no english native so terms like urethra might seem weird but it is the exact translation for　尿道. Feel free to correct it to more common english if you need to.

I enjoy doing these, will check the translation request tag for pending translations.

Well as an English native I'd have to say that in regards to porn the vocabulary used tends to be more base. So rather than "urethra" I'd think that "cock" would be more appropriate in this situation.
