Ama Rio Explodes a "Giant Willie" Hot Water Bottle (MP4 - 720p)

Description: People send the lab all sorts of unusual things to test.  occasionally that includes a hot water bottle with anatomical features.  while we've had them with breasts before, we believe this is our first "willie."  it's british, which means it's made of some very thick rubber.  while ama is exceptionally strong, she does not have enough puff to expand this thing, so she turns to the foot pumps.  after a while, it's thickness makes everyone quite nervous, and leads us to improvise some protection by throwing a lab coat over it.  fortunately, no harm is done, except to some fittings that sacrifice themselves for science.
