Free Tingler Number Three

This is the Tinglerst Tingler of the free Tinglers that Chuck is offering for free during the COVID 19 pandemic. In it, our plucky research doctor protagonist journeys to what he believes to be a vampire infested castle to learn what he can do to help prevent the spread of the Trotter disease currently running rampant1. There he discovers two vampire unicorns, learns how to cough into his elbow to prevent the spread of disease carrying droplets, and has a night of explicit sex.
