This is a story in the Collar Club.
Doreen has hidden a fantasy from her Master. After finding out about it he plans to teach her a lesson on hiding stuff from him.
A Future Sex Tech story This is a wacked out story, for sure. Not exactly like my usual stuff, but there's lots of BDSM. It's set in the Future Sex Tech universe after the fall of the CCCP (Conservative Christian Coalition Party). Fun with technology and biosculpting.
You're a young man coerced into sex with a forty-something convenience store clerk only to discover she's your tightly wound middle-class mother's volatile, hard-living ex-girlfriend. You are a sex toy they're using to torment each other.
