We asked Gemma to perform as many movements as she could in which her boobs would get jiggled, bounced, swung and so on, you get the idea. Here's the output of her creativity. She starts off on her back and we spend time looking at her playing with her boobs, she then sits up and performs more boob bouncing and then we get some hanging boobs as Gemma leans over. Marvellous. Slow motion? Oh yes, there's slow motion too!
