I enjoyed the hell out of this game. Haven't laughed like that in a while. The only other AVN which managed to make me laugh this hard was Eternum. I also loved the characters, especially Vineeta and Noelle. Though, I have a minor, personal problem with not the lack of penetrative sex itself, but the way it was presented/executed.
The lack of penetrative sex is honestly beginning to come off as weird at this point. I don't even get why someone would want this as an author. Things like being constantly interrupted and it being played off as a joke is the shit you see in media that CAN'T show sex scenes. Oh, and it's never funny. Like at all. It's the same kind of humor as constant interrupted confessions that the author plays off as a joke.
I genuinely wouldn't mind not having penetrative sex till a certain point, or at all, even. It's the interrupted scenes that annoy me. For example, the scene with Grace at the party felt completely natural to me, because we were given an actual reason for it, not an annoying interruption. The interrupted scene with Stella was just annoying, but the one with Miya already felt forced.
Though, again, not sure why as an author of an AVN you'd even want to put off penetrative sex scenes until a certain point this far into the game. The only reasonable explanation I see is that sex somehow makes Gary awaken more or some shit like that, which really would be tied to the plot progression.
