Gaming (Manhunt 2) most horrific sex scenes

Whatever your opinion about sex in videogames, the simple fact is this: games won't really be taken seriously as an art form until they can get certain things right, and one of those things is sex.

The results of their endless efforts tend to range from mildly off putting to outright mortifying, with varying levels of ugliness and hilarity in between.
