Lollipop!

While still a child, Lollipop falls in love with her orphaned cousin Silvio, who has been raised as a member of the family by her father, Dr. Arnaldo, a highly respected government official. Years pass, and to Lollipop's dismay, Silvio becomes engaged to her cousin Leticia. During the engagement party, the enraged Lollipop seduces Silvio, and sometime later, she reveals to Leticia that she is pregnant as a result of the encounter.
