The slave is on a high bench, ready for to be ridden by Jane and Hanna.
With a shout "lets ride to mexico" Jane mounts his face like a horse and animate Hanna to mount his body the same way.
The two make riding moves, humping and dropping their asses on the poor slave.
In the half Jane leaves the scene and Hanna rides alone, easier for the slave?...
no way, newcomer Hanna shows with ridingmoves and repeatly buttdrops on the face, throat and body, that one women's weight can be enough for squashing him good.
To the end Jane comes back and they finish him again with a double face-and bodyride.
