Colonial water pump 

When you meet someone special that is a half arm amputee. He/she grabs your penis with their good arm and you crank the "nub" pumping it, up and down like a an old fashioned water pump. The stroke is depending on what speed you want them to go

**Works the most efficiently when you are face to face

Bro, she gave me a colonial water pump last night and it was awesome
