I heard a firsthand story about a woman who ended up in a friends-with-benefits kind of relationship with an older man she met while working part-time at a convenience store. They often talked during shifts, and gradually grew closer. One day, he gave her a remotely controllable vibrator and told her to insert it, then continue working her four-hour shift. Even while she was operating the cash register, he would operate the switch, clearly enjoying himself, while she found the experience extremely difficult. The erotic experience during work was incredibly real and shocking.
