In Lady Blackdiamoond’s Sissy Academy, the devoted man is taught everything necessary to become a fully developed sissy. The fifth part focuses on the sissy’s fuckhole, as she must be easily accessible for every cock size. Since Lady Blackdiamoond is already wearing her strap-on, she immediately gets to work and thoroughly fucks the sissy with pleasure. The little doll moans under the hard thrusts of her Mistress, and the cocks grow bigger and bigger. As a sample of what is to come, the sissy is first given a proper deepthroat, before they disappear once again into her tight fuckhole.
