There's a thighjob and a titjob from Diane, that you get to by clicking "Flirt with Diane" several times and that's it.
It's especially annoying since when you promise sex scenes, you should give, you know, SEX SCENES.
The dev also has like no real schedule (he keeps to the line of "update every two weeks" but he has never made that target), and he is doing the typical "build so slow that it'll be abandoned before vaginal sex even comes up in conversation" content updates. Seriously, this has been up on this site for approaching 2 years. It's shabby.
