Interesting you brought that up, a few weeks ago one of my shapely neighbors was having a colonoscopy done and that scenario did cross my mind. That is statutory rape but I wouldn't doubt it's happened.

I do remember Veronica Hart doing a scene resembling that many years ago. She was in a dental chair under anesthesia - the nurse spread her legs and started eating her out while the dentist jammed his cock in her mouth. In retrospect it was a perverted scene but fairly mild compared to what's out there today. Never forgot it though and I often wondered how Veronica rationalized the scene to
her two sons. This aged whore is always railing on about how depraved and cheapened the porn biz is now.
