A sexual act where a man and a woman have sex while they are both being anally probed (i.e. fingered, fisted, etc.). Because of the difficulties in reaching to perform it, this would usually be done in a threesome/foursome/gangbang scenario.
When a bodybuilder anally fists two petite women and moves them around like puppets with one bashing the other with a large dildo shouting ‘that’s the wayto do it’
