Pump up your Uterus with an Air Compressor
 

Pump up your Uterus with an Air Compressor.

All you need is a piece of rubber to tightly fit into the uterus opening
and seal around the air hose. The tighter the seal, the more pressure
you can apply.

Once the uterus has held 100psi for at least 10 minutes, it's ready for
any man's penis to provide sexual intercourse.
