I'm thinking of writing a story where 2 or more couples on a vacation rent a mansion and hides one of their own bound and gagged. After being rescued, the captive says their prowler was masked. So as the weekend goes, someone in the group is capturing, binding, and gagging them. Here's the think: it's all a kinky sex game. The Prowler is trying to capture everyone.
I've been debating various gimmicks.
-Maybe the Prowler is a couple who aren't in the main party.
-There is locking bondage furniture in the main hall that the Prowler is trying to get the captives to and there are keys hidden around the mansion.
-Each capture costs the captive an article of clothing. Naked captives are displayed in the locking furniture.
-Perhaps they start out drugged and awake to find themselves wearing locking bottom harnesses with vibrating sex toys inserted into them set to a three hour timer with keys to their harnesses hidden.
Thoughts?
