Sabrina was fully aware that she could be used for "practical demonstrations" when she signed up as a model for Human Sexuality Class. She didn't expect to be getting so excited about it though… For a start, there was another model called George and the demonstrations very much involved him too. What started as a job was quickly becoming the hottest adventure of her life. Are you ready for a filthy, fun (and possibly even weirdly educational) adventure through the male and female orgasms, anal sex, squirting, threesomes and more. — In addition to the main novella, this book also includes a bonus short story called Research Assignment, set in the same cinematic universe, that was previously published by Max Delany.
