My BDSM Milking

I confess to Gerry that my nipples have started leaking milk and he gets very mysterious indeed.  He tells me to meet him at an address the very next day and not to tell his girlfriend anything.

When I arrive I'm presented with a strange system of apparatus.  Gerry wants my milk and I want to give it to him.  Strap me in and take it from me, Gerry!  I'll do anything!
