It's a great game. Two things would make it almost perfect. If they add more sex positions (more cowgirl, etc.) with different camera views for each girl, and SOUND EFFECTS(Specifically women moaning and orgasm sounds)please! That would make it 20/10. I would pay for that!
I love the music in this game, however I will admit more sound could really bring it up a notch and make it more immersive, but the story lines and game-play for me are what make this game so unique among it's peers. That being said, I wouldn't mind leaving it downloading overnight if that's the trade off, it would bring back memories of times passed. But your game is already 20/10 for me regardless ;)
