look up any word, like mexican microwave:
Mittening can be defined as a sexual act between two consenting partners where the female's body serves as a mitten for their partners hand.
Mittening: One partner, who can be deemed as the "receiver" and must be female, remains calm while the other partner inserts their four fingers into her vagina. The thumb must be left free. Lubrication is often needed. Once all four fingers have been inserted, the thumb is inserted into the anus of the female, again lubrication is often needed. This then creates a "mitten" for the hand.
