Sorry for criticism, but here we go:
The world feels too empty and artificial (I am guessing due to money/time constraints). The women behaviour seems too improbable and robotic. The constant panty shots also somewhat distract from story (that's probably more of a problem for me rather than everyone).
Please, add more non sexual interactions in the world. Otherwise it almost feels post-apocaliptic. We exist in the liminal space, where there are only a handful of women and one weird "friend" that we spent no time learning about, but for some reason he throws us a party.
