Here is the Sex Scene from The Witcher 2 for Ves in case you missed it. I think depending on the decisions you make you might not get to hook up with her, either way here it is in full 1080p HD:
******To get this scene you have to take part in the fights at the Kadweni camp, as you progress through the fights Ves will challenge you. After you beat her go talk to her at her tent which is on the outside of the compound and to the right. It's near the river and by the group of guys who you can fight with for sport.
