Because there is literally no upper limit to Japanese perversion, this is a video demonstration of a pair of motion-controlled anime boobs. Using a Leap Motion gesture input device, a user can sadly jiggle boobs to their heart's content. You don't actually get to feel any cleavage though, just jostle it around with air gestures. That's sad. They don't even move like real boobs either, they react like rubber. I'm not saying whoever developed the program hasn't experienced the real thing before, but I wouldn't be surprised to find out the nipples under that bikini top are actually smiley faces.
Keep going for the probably NSFW video.
Thanks to TBTMH, who agrees that when it comes to snuggling, nothing beats a nice pair of titties to curl up beside.
