Mobile Sperm Bank 

A Mobile Sperm Bank is a garden variety type setup, whilst essentially female, that appears to be hoarding male ejaculate. It is unclear what happens to the loads after entering and whether they are offered as artificial insemination
solutions for infertile men or if it is frozen to later be carved and whoreshipped at the MBSs birthdays and other ceremonies of whoreship

Bro, I know it was short lived but we were in love, man! Turns out she's a serial cheat. I didn't even know they had mobile sperm banks! This will be handy through this pandemic.
