So far, this is fantastic!  The story is interesting and the characters are compelling.  The sex scenes are well done and fun, and the relationship developments that drive them are very arousing. 

Here are my "complaints", minor though they may be.  First, I think that the option to make a couple of the women SUPER voluptuous or more modest, should be reversible.  The fact the option exists shows that the dev has created graphics for both versions.  Second, while I love big breasts, I think some of these women may cross into the realm of "too much of a good thing".
