Canal Bank 

When a woman collects or "banks" the semen from multiple men in her vagina or "canal" in order to increase her chances of getting pregnant.

Tracy's having another baby. Apparently she "canal banked" the local football team after they beat Rovers in the derby match a couple of months ago.

the carnal reserve bank 

Analogous to the federal reserve bank except for the spank bank. The carnal reserve bank is the central location in the brain where all pornographic,erotic and sexy images,scenarios and fantasies are stored for spanking stimulation.Where as the spank bank stores recent and favorite images,the carnal reserve bank keeps older or less frequently used images.

I got tired of whacking off to the same old fantasy so I summoned up some different material from the carnal reserve bank.
