A Dutch sexual act.

This act requires a male dog. While doing a girl from behind show your dog some dog porn to get his little wiener erect. To make his wiener warm and juicy, pour some Dutch molten cheese over his cock. Now it is time for the great trick. So while you are still smashing this girl, smoothly replace your cock with your dog's wet, cheesy cock. While your dog is fucking your girl, silently walk into your girl's view. She will be very surprised and looks behind her and sees the dog. Then you scream: DERPCHEESE! And you run out of the room.
Friend: Yo did you slam that girl yesterday night.

Me: Yeah bro but I was not digging the sex so I performed the Derpcheese on here.
Friend: No shit?
