Devious device instruction manual (pt. 1) (Patreon)

Hmm..? What is this you found? It seems to be an old instruction manual / advertisement for a device that appears to be... Rather interesting. 

The manual is worn-down and yellowed but you can still make out what it says. You become immediately intrigued by what this devious yet instantly arousing concept is. The manual was slipped in between a dirty magazine that your co-worker was about to throw out with other kinky media ranging from magazines to old VHSs. Did they notice it being there? Surely not.

Intrigued by this old relic, you decide to go back to see the stash your co-worker left in the dumpster behind the office building you both work at.
