Dog Fisting

When engaging in sexual intercourse you use your hand and mimic a dog as if doing a shadow puppet. Then proceed to insert your middle and ring finger in the vagina and your pinky and your partner's anus with a back and forth motion like you're hitting a punching bag.

(for enhanced experience you can imitate the barking/howl of a dog. While opening and closing its mouth with your hand)
