You dig up one of your girlfriends dead relatives (or alive), chop them up, put it in her pussy and fuck her. Then, have her guess who the relative was and which body part was used.
My girlfriend was happy to see her dead mom again, until I did The Relative Surprise. Now her mom will forever be with her.
