Reverse Pegging

Reverse pegging is a sexual act in which a man wears a strap-on harness to penetrate a woman sexually (vaginally or anally). His penis is not used for this act and may be confined in a penis cage or may simply not be used.

The opposite of pegging: you put a fleshlight inside your girlfriends asshole and then proceed to fuck it

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.
