To claim this quest:
Ari is always devising new, devious ways to build machines for penetrative purposes, but a classic favorite is what is commonly known as a fucking machine. There are many kinds of these machines with different features, but ultimately it involves a machine with a phallus on a piston that moves back and forth, usually granting some control over speed, depth and angle. Ari’s machines are steam-powered, but you can probably find one that plugs into the wall or is battery powered. Another great variation involves some form of restraint, keeping the recipient nice and still for maximum control. Play with a machine like this and you can claim this quest.
