Yeah I don't if the Kinect is really right for the way he's implying which involves taking your pants off... or if any video games is right for that. First off, the big downside is that to play kinect you have to be standing up, kind of hard to imitate a variety of sex moves doing that apart from the traditional pelvic thrust which can get tiring. Now it will work great for the Japanese 'Rapelay' type games where the controls are more centered on your hands, which I'm sure we'll be seeing humorous reviews of soon enough. But again, taking your pants off? I don't see it...
On the other hand, wouldn't the Wii-mote or Move work a little better for this? You have two controls to immitate hand movement, not as precise as the Kinect but it still works. Then more importantly it would be easier and far less strenious to use the buttons & analogue sticks to move your on screen avatar into various positions, then with the right hand (and especially on the Move) you have a perfectly good dildo like object for thrusting, and the left hand analogue stick can be used for tongue control. For the former rather than relying on any sort of personal physicality or endurence like the proposed Kinect games would require the mechanics behind the thrusting would be handled by the game and resemble a Zelda fishing mini game. Go to strong & fast you snap your line, too slow the fish loses interest and swims away, so you have to find that controlled sweet spot to maintain your control and reel that fishy in!
Personally I always thought it would be hilarious if a company like Rockstar switched from an ultra violent game like Manhunt to a hilarious sex game like Manwhore. Where you play a man who has to whore himself out to women, with RPG elements where you have to start low on the chain and gain reputation, experience points for attribute increases, and of course cash for grooming, bling, various natural (or not)growth enhancements products, etc, working your way up the ladder until you reach the elusive high class super models clientele.
