I would recommend it for the sex scenes, they are very good and there are a lot of them, and they have all of the different bases well covered. It's definitely 18+ only. It's fair to say that about 3/4 of the game is rape and pretty hardcore sex scenes, including some very specific fetish stuff that not everybody can stomach.
If you are not into the rape/sex/fetish stuff, and you just want to play through a plot heavy vn that, then I wouldn't recommend this. If you take away all of the sex scenes, this vn is below average. Instead I would recommend "Kara no Shoujo" for 18+ vn, or "Narcissu" if you are under 18.
