Flashing (and sometimes more) is one of KK's favorite ways to alleviate boredom on long road trips. Our first experience beyond just flashing was about three years after we started doing the hot wife thing. We ended up in the parking lot of a Pilot truck stop; KK got banged in the sleeper cab of a rig, followed by a wild MFM threesome in one of the facility's shower rooms.
This started out as KK joking around, when I dared her to flash her tits to a trucker. The game escalated, from tit exposure to full-on nude masturbation, with KK splayed out, finger-banging herself into oblivion.
