I like the game a lot so far. Personally I prefer dickgirls to have balls rather than vaginas, but not enough to stop me from supporting this. The renders look good and the girls are hot. Although I think that the girl's dicks being quite so big is a bit silly, they do at least recognise that they are monsters; some games I've seen have girls treat dicks like that as normal.
I'm not sure who I prefer more, "Mom" or "Aunt" (don't they have names?) - Mom is extremely beautiful, but Aunt is such a dirty slut. Maybe Mom because that fingering scene with her screaming in ecstasy on the massage table is something else. Once the Summoner has learned the special fingering technique, it would be nice to be able to use it on others.
One other thing I'd like to see would be some expansion on the existing timeslots. For example even after you've finished Mom's quest line, it seems a bit odd for her to be so freaked out in the kitchen, and after Sister and Delyla are the Summoner's little bitches, peeping on Sister in the shower or the sauna probably shouldn't be a problem. Also nice would be adding the option to choose between blowjobs or fucking in the living room.
There are also a few bugs to report, as others have mentioned the instant arousal on self is only usable once. Not once per day, just once. And the quest logs for Sister and Aunt don't say "End of Content" or give a hint. Also after each visit from Enlil I notice that the UI with the time, who's in which room, etc. doesn't update until you move to another room.
