This is a hard one to rate. I wanted to give it 1 star for the content-- There's really nothing here. It's like 6 stations: Couch (for seated cowgirl), The chair and the kitty cage (both for blowjobs), the stockade (for doggy), the X-Cross or the chains for toys and sadism, and that's about it.
What is there is extremely well done, though, with an eye on user experience. Even adjusting your height or turning around is done well, with the view shrinking to a pin-sized hole for the duration of the move to keep you from getting motion sick, a solution similar titles haven't bothered with. The animations are nice and the amount of customization available is impressive, if only superficial and ineffective (you always have the same face and body).
At the end of the day though, this isn't a game, it's a collection of sex poses like Fallen Doll or Sexbot Quality Assurance Simulator, except those have a lot more content and physics, respectively, and art styles that I can actually get off to instead of stick figure anime girl with bolt on tits, no lips, eyes taking up half the surface area of her head, making injured cat noises over and over. Some people are into that, I guess, but to each their own.
