Water pump

The WaterPump : originated from the outskirts of Toronto

It's when woman laying on her back holding her black King's ankles while he holds her ankles back. The second black king will then slide inside her and each pump of her ankles will allow the second king to reach the depths of pleasure she did not know was possible - hence the waterpump.

Breast Pump

When you meet a woman for the first time and she has massive jugs but once she produces offspring her output is about one milliliter. You cry while watching the breast pump producing the same amount of milk as male ejaculate. This, of course, forces the man to spend immense amounts of money on formula.
Yo, I knocked this chick up with 36d’s thinking I wouldn’t have to spend money on formula. We tried the breast pump but with limited success.

Bro, that sucks. Should have made the baby with her mother. Heard she’s a real milk machine.
