I think I may have invented something new.   It stared out as a bondage device but I do think it is helping to enlarge my breasts!

I have always been handy and creative. Years ago I built a couple basic
breast clamps that I use from time to time but lately I have been
working in the shop and visiting the hardware store to build a different
kind of breast bondage device. This device does 3 functions, breast
clamp, breast nipple suction and breast nipple pulling, all at the same
time, if you want all three, or separately.

The frame is made of soldered copper pipe with the bottom and top
hinging around a common pipe located about 9 inches away from the body.
The top and bottom pipes are connected together with a single threaded
rod with a tightening knob, located in the middle. From this common
pipe, two vacuum operated two inch nipple cups are connected by threaded
rods. Each cup rod has a tightening knob. The knobs were found to be
easier to operate than wing nuts. Vacuum is supplied by a small hand
operated vacuum pump.

Here is the completed device.
