Casey V. is here for a routine check up with Dr. Lux Lives. Little does Casey know though, is that Dr. Lives is interested in trying new...experimental procedures. She locks Casey into her medical chair and tells them about how disgusting their penis is. Casey is frightened and confused - this isn't what they came in for! Dr. Lives won't be persuaded though...she knocks Casey out...who then awakens as Cupcake. Cupcake, formerly Casey, is livid to find her penis gone but soon marvels at her breasts and sensitive pussy as Dr. Lives guides her in exploring her new body....
