Black Hole Whack-A-Mole
When you have dodo coming out of your bumhole and you play around with it a little so you squeeze it back in (like how a black hole sucks things in), then rebirthing it back out, then in, then out, etc. This repetitive movement is of similar fashion to the moles in the game Whack-A-Mole
I like to perform the Black Hole Whack-a-Mole technique because it feels as if someone penetrated me with their massive cock in my anus
