Fucking machines are great––but the heavy-duty models can cost a fortune, weigh a ton, and take up a lot of real estate in even the most ample bedroom (or dungeon). Enter The Power Box. It may look like a mild-mannered toolbox, but this affordable sex engine is both portable and potent, powered by a 4.5-amp motor that allows for slow (40 rpms) and fast (80 rpms) speeds. Just slap a Vac-U-Lock dong (sold separately) on the end of the .5-inch diameter steel shaft, plug it in, and plow away. Weighing in at about 10 pounds and with a stroke length that can be adjusted to 2, 4 and 6 inches, the unit can be packed up neatly and discreetly when playtime is over. One word of caution: When your neighbor comes to borrow your wrench set, be sure to hand over the right toolbox.
