Dont get it!! Why would you want gorgeous big breasted women at the right height and angle for maximum cleavage to do that? WHY?
Sorry I have to go now and do my daily check in to the mental asylum! LOL!
One suggestion though.. I think the tubes should be made from clear perspex and a camers inside looking up!!

The babes have to be rubbed sown in baby oil and wear sting bikinis/g-strings!
What a show that would be!
