TMZ obtained surveillance video of nudey-dudey exploits around the Erotic Heritage Museum - which was featuring an homage to kink on Valentines Day and after finding a spot to hide in until closing time, the couple went on an after-hours room-by-room sex spree.
The house lights go down and the banging began in earnest. The couple didnt hold back as they moved around but they didnt realize security was watching.
Dr. Victoria, who heads up the museum, tells us security alerted staff members who returned to bust the exhibitionists (geddit?) Their half naked run of shame was possibly the best part.
