In the first lesson, the girl is instructed in the use of enemas as preparation for anal sex. An enema is administered, and the girl is shown how to prepare and self-administer one in readiness for anal use by a Dominant. She is then fucked anally. In a second lesson, the girl must perform her own enema in preparation. She is then used anally. After the Dominant has cum in her ass, she must clean his cock orally ("ass-to-mouth") to learn the importance of having prepared properly. A girl may apply for an exemption to this class, if it violates a Hard Limit.
