All tied up or have someone else in this position?  These bags are great for long-term play, especially when someone really needs to relieve themselves.   These bags also are very helpful when extra electrical power or intense pulsating is applied to the ass or cock and one just naturally relieves themselves without any control.  No mess is a good thing!  You know what we mean.  :) 

These bags are heavy duty with a one-way intake valve and a quick twist valve on the bottom for easy disposal of fluids. A quick trip to most home improvement stores will allow you to purchase a small roll of rubber or vinyl tubing to make the connection to the top of the bag.  Since we all have are methods of securing things over the head and head or shaft of the cock, we will leave that task to the DIY minds.  A heavy condom or external catheter works nicely too.  

The elastic latex free straps have adjustable buttons that can be removed and re-inserted anywhere you want along the elastic strap for a good comfortable secure fit.  Liquid capacity is 600ml or right at 20 ounces.
