As you can see from this archived snapshot of the site, there were progress reports, graphics, and animations signifying that an earnest effort for a sequel was taking shape. Unfortunately, most folks believe that the developer, Pixel Factory, had to cease work on the project as adult gaming projects such as this were violating several laws in PF's home country
at the time. Porn is a no-no. Since then, if I recall correctly, the only other time PF popped up in the past couple of years was when someone tried to steal their work and profit it off on Steam. Of course, Steam rightly removed it. Thus, the answer to your question is, "yes", a sequel was planned and much of the work already completed, but also "no" as it will never be completed as Pixel Factory was forcibly dispersed. It is what it is.
