sperm bank 

A fun place to go to when you're broke and/or need to get off. They let you borrow their free porn so that you can rub one out into a cup, AND you get paid! Make sure you don't get a magazine that has "water damage"

You get $50 per visit, but the thing is you have to go at least once a week and go through a pretty thorough screening process. And after 20 or so successful ejaculates, you get $60 per visit.

Getting paid to jerk off. What a deal! Sign me up.

Personal Sperm Bank 

Any person, male or female, gay or straight, who allows men to cum inside them without properly cleaning between sexual encounters. This allows for more than one person's sperm to be inside them at the same time.

"I screwed that blonde chic last night but her pussy felt all wet and sloppy."
"That's cuz I fucked her just before you did and she still had my cum inside her when you tapped it. Dude, you were fucking a personal sperm bank!"
