I didn't manage to find author and original title. Translated SFX, but wasn't too sure about 2 or 3. If anybody has higher quality images or the missing info, let me know...
The original author was a japanese artist by the name of Karimuru, who can be found with that name on most sites. Was a great artist for giant fit girls and futanari many years ago but hasn't posted anything in as long sadly.
Incidently, if you're translating oldies but goodies now, any chance of checking out HIK Giga Mite 2? Can find that on this site as well.
