cookie monster 

The act of penetrating your female partner's rectum with your thumb and inserting your other four fingers into her vagina. Move your thumb and fingers as you would a sock puppet, thus creating a cookie eating monster. (Voices are encouraged for maximum arousal.)

My girlfriend likes to role play, so I suggested Sesame Street. I rolled her onto her stomach and gave her the cookie monster until she squealed like Ms. Piggy.
