Sperm bank robber 

An individual who seduces you, (generally female) and begins having intercourse with you only to make you release your semen, which they promptly steal to either sell or donate it.

Last night, when I was coming home from the bar, I swear this lady was a sperm bank robber, luckily, I didn't fall for it...
