Married couple get divorced so their girlfriend doesn't get jealous

Cristina and Benno Kaiser were happily divorced after 12 years of marriage. Even though they are together, they are no longer a couple. They are a trio. They both have the same girlfriend, 21-year-old Sierra Kuntz, who they met working at a reptile pet store at the local mall in Nevada. Sierra plans to marry either Cristina or Benno.
