In the horny imaginations of Harry Potter super-fans, Professor Snape is a BDSM sex god and Hermione Granger is a squirter. So say Potterotica hosts Allie LeFevere, Lyndsay Rush, and Danny Chapman, who explore the mind-bending universe of Harry Potter erotica every week— complete with dramatic readings. They explain which magic spells are the best for sex; why nobody fantasizes about Ron Weasley; and how a tech-savvy grandmother became the steamiest Potterotica writer on the web.
