Most of my boobs bouncing and jumping videos are about exercise, so I'm usually standing up. I decided to make a video of boob bouncing and shaking that is only in the lying on my back position. This video is based on an idea for a custom masturbation video that didn't quite work the way I wanted it to. But this turned out way more epic than the masturbation video would have, I think. If you were waiting to see how my boobs move when I am lying on my back, here it is. Short intro in Spanish, then just lots of movement in various positions. Every position has regular speed, and various speeds of slow motion so you can see all the details.
