rusty horse

When a man sticks his head up another man's ass and they pretend to be a centaur.
The man on top can shoot a bow and arrow, but it's optional.

Centaurs are beautiful creatures, but rusty horses are more majestic.

The other day I went to the rodeo and rusty horsed in the stables with my partner, luckily he didn't bring his bow and arrow this time.

When you and your girl do anal without proper preparation and on the pullout there's poop left over on your dick.
