Rusty Vending Machine 

When a guy finger fucks a girl 8 times as if he was inserting quarters in her, then he pushes on her nipples while he reaches around and sticks his fist in her ass as if he was getting his snack.

Lets go over to Audrey's house. I heard from many guys that she likes the Rusty Vending Machine.

rusty sewing machine 

The opposite of a rusty trombone. Internationally hand signalled by pointing your index finger toward a fictional v-hole while feigning to lick an imaginary fecally stained sphincter.

The other night when my girl came over, instead of getting a rusty trombone I thought I'd do something nice for her. I told her to use the Kamode but not to wipe. Tonight was going to be her special night. The night of the rusty sewing machine.
