Between two persons with male genitalia. One wears a strap-on backwards and fucks the recieving participant's ass by having said participant doing a head stand with hips and knees bent 90° in a sitting position. The participant with strap on, stands up and sits down on the chair structure formed by the recieving participant, inserting the strap on into the recieving participants asshole.
