Os Capiroto's surgical suite becomes a stage for the most intimate of performances. A brother and sister, under his knife, wake up in each other's bodies, their identities swapped. Confusion turns to curiosity as they explore their new forms. The sister, now endowed with her brother's cock, strokes it, feeling its power. The brother, with his sister's pussy, rubs it, feeling its wetness. As they come together, their lust overpowers their shock, and they fuck, their bodies merging in a symphony of taboo desire.
