Ava Little, a stunning and submissive shemale, finds herself in the capable hands of a kinky doctor at Assylum. As a new patient, she's prescribed an intense course of anal training, designed to prepare her for the most rigorous of pleasures. The doctor, a stern and dominant figure, uses his medical expertise to push Ava's limits, gagging her with his thick cock while she dutifully takes his hard, rough anal fucking like the good little doll she's been programmed to be. The training is brutal, but Ava's appetite for degradation grows with each punishing thrust.
