The Last Unicorn

A man, or woman secures a dildo to his/her forehead. This dildo is then forced into the woman's vagina, until orgasm.

It is customary for the "unicorn" to nay like a unicorn and kick with the back legs.

"I performed the Last Unicorn on Jill last night, and I wasn't the only one naying."
