Before we go any further, we're going to wager that, due to the jiggling booty on display, the repeated grunts of satisfaction, the dripping bodily fluids and the attire inappropriate for most tennis courts, this ad for Top Spin 4 could be categorized as NSFW.

It could also be argued that this commercial, featuring Serena Williams ("the world's sexiest tennis player") and Rileah Vanderbilt ("the world's sexiest tennis gamer") is pushing the boundaries of good taste for a video game about professional tennis. But maybe this is what it takes to get people (or just horny dudes) to notice 2K Sports' latest Top Spin game, a title that's not known for its titillation, sweaty cleavage and spurts of flame.

Though it may be informative. Did you know that Top Spin 4 has PlayStation Move support? And that we've apparently crowned the world's sexiest tennis gamer at some point?
