I was looking for doujins in Spanish I could translate to English and I found this one. So I decided to translate it, but I realized that the original language was actually in Japanese a little too late. Oh No, I don't know Japanese. That means I unfortunately cannot confirm the validity of the Spanish translation when compared to the original. I simply translated the Spanish version to English. Therefore if people could be so kind as to help point out any things I got wrong, I'll fix it ASAP.
Skimmed it and found some minor grammar goofs so far, not sure how to contact you to send you what needs to be fixed, though. Will do a more thorough reading tomorrow.
