I was thinking if there was a item that could let you carry as much ball sack mass so you don't have to be immoble, but it has to be worn to use it... and if you want to have cum ocean fill testicals, and still be able to move, then this is the thing for you, aswell as a dick growth item. This would also add seens as well, because since you are so heavy and cant move while with all that mass, the partner will have to do all the work(or the item you have forces the person with sex or a blowjob
), and in the end they are covered in a cum lake, or there womb is so large they could be imoble until the cum flows out or gives birth to somthing
