I liked this game, I did.
But as the game has gone on, the effort on the Dev's part to get his russian translated properly has just disappeared and the gigantic file size makes downloading the updates a chore. Not to mention the forced change into an NTR game just so you can advance to plot where Mark would allow his little sister to be abused, which is something the character's back story suggests he'd rather die than let happen.
Also that your sister is apparently brain dead and keeps going back to that habit no matter how many times she's almost mouth raped on the bed. You'd think it happening twice would be enough for her realize "Maybe I shouldn't be doing those things again."
I just can't keep playing this one. It's getting absurd now. It started out great, guy gets dream job with shady dude. Uses time and energy trying to corrupt his daughter and turn his wife against him in order to eventually get rid of him. What it's turned into is you dragging your sister into a horrible situation and doing anything desperately to escape it.
When the game is completed, and the file size is no longer approaching 8 gigs, then sure.
