XStoryPlayer is a 3D-Adultgame where you need to interact with the girls to get them to have sex with you.
It's a very interesting game which enables you to play certain stories with different girls. Currently there are two stories in the full version of the game but there are still more being developed. On the mainsite of the producers you will either be able to buy the full game for 9 dollars (around 7.50 Euro) or download a demo with a short playable chapter of one of the stories in the full version. Since I have no idea how to link things I will just post the name of the site: http://www.xmoonproductions.com/
Since it's a small team which is working on the game they still need support.
If you want to read a more proffessional introduction to the game please go in this site: http://offbeatr.com
and search for XStoryPlayer 9.9 in the Project Status section on the right side.
