It's obvious a lot of effort has gone into this, and despite the bugs and glitches (which are understandable considering the game is pretty new) it has the makings of an amazing game! I'm really looking forward to seeing future updates to this!
It'd also be nice to see a few things, such as the ability to see the player's torso rather than simply a disembodied penis. And to have the girls react to having their breasts/genitals touched. Maybe an option for cunnilingus? Whatever you decide to do with the game in future, I'm sure it'll be great. ^^
