This small erotic masterpiece by the great Peruvian author tells the story of the sensual and beautiful Dona Lukrezia, the forty-year-old stepmother; of Don Rigoberto, the father and husband and imaginative lover of Lukrezia; and of Alfonsito, the unsettling little son who shows an alarming attachment to his stepmother, causing everything to flow and waver through his angelic presence in a house where desires and yearnings seem to know no bounds.
