Linear and very short.
You basically just have to click on and on until a little bit of stuff happens.

This is a good game, while some of the preview images are not in the actual game and the only sex scene is 1 blow job scene, the orgy scene at the end has nothing in it just an image of the before and just references to it after no images, no nothing of the actual orgy. But it is still a very enjoyable experience.
