Tummy movement and distention (for the ladies)

Hello to all the beautiful ladies, I am curious about the female experience of having large and deep penetrations which cause visible movements in your tummy. I have seen videos of men with large dicks, or large toys, create ripples in the belly. If any of you ladies have experienced this, does it add or detract from the experience? Are the feeling pleasurable? As an illustration of what I am referring to, I have attached a link to a video demonstrating what I am referring to. Thanks

I don't pretend my contribution is very pertinent because I never experienced very wide and deep penetrations, but the video is quite explicit. Maybe the riddles of the belly are just the consequences of the strong vaginal contractions during this intensive penetration by this machine. When the vaginal contractions get very intense and un-controlable, the reached orgasm is often very nice and all the female body can be shaked.
