The RustyCrustacean is a sexual act where; a female lays on her back and her partner puts their thumb inside the vagina and four remaining fingers inside the anus of the female. Then, the partner squeezes their fingers together (reenacting the movement a crustacean's claws make when closing) causing fluctuation of the vaginal and anal region of the female. Maximum pleasure is promised if performed correctly.
I contracted a case of the crotch crustaceans from the trousers I purchased at the Salvation ArmyThrift Store. Of course the old lady just ain't buying it...
when you have sex and your intercourse partner cums on you're vaginal area and you forget to clean up and it dries up and stays on your vagina and it hardens into a crust
