To claim this quest:
Part of a series of machines that work with just the power of your own muscles, the rocker style fucking machine is another favorite of Ari’s. A phallus is affixed to a seat that drives the phallus up and down as the machine rocks forward and back. The mechanics are simple, but effective, and an analog device like this can be a little easier to get your hands on than a full scale fucking machine. Play with a rocking machine to claim this quest.
