Oh the fun that would be had on that...! But being serious for a moment, it looks like it would rattle your brain too hard. Yikes.
Mmmhmm sex would be amazing on this, cause a girl wouldn't need to have the bouncing motion down because the bed would take care of it . *cough* *cough* But yeah anyways...now that I've broken every rule there is on appropriateness....I'm sure he's developed chronic neck and back pains, as well as concussions from that thing. It's crazy.
