A couple with three kids that had been married for more than 10 years is getting a divorce so that one of them can marry their mutual girlfriend and add her as a legal guardian for their kids.
Cristina and Benno Kaiser tell the strange-as-ever BarcroftTV that their relationship with a 21-year-old woman they met at a pet store in Vegas, Sierra Kuntz, is permanent.

“Cristina and I decided this was something that needed to be done in order for Sierra to understand the depth of how much we love her and want her to be part of our family,” Benno said. “She is going to be legally considered a parent to the children and, more importantly, it will show her that this is not a temporary thing, we both love her and it’s something that’s meant to be permanent.”
The Kaisers have three kids: 11-year-old Isaiah, 7-year-old Rebecca and 6-year-old Brianna.
Cristina Kaiser said the her bisexuality led her to suggest an open marriage to her husband. Soon after, Cristina offered Sierra her number at the pet store while her husband was there.

Sierra Kuntz said she was hesitant at first because she “worried that I would be disposable and that this was a phase they were going through.”
Now they all live under the same roof.
Benno said the three have a threesome every night, to some degree. He said it’s “busy.”
“We share a bed together, we share everything together, so since we met Sierra we have not had a night that we don’t all involve each other in some sort of sexual activity,” he said. “It’s busy. There are lots of hands everywhere. The beauty of what we do is that we can have a very active sexual life and it’s completely safe and it’s with people that we love.”
The Kaisers say their kids are on board with it, with the kids calling Sierra “mommy Sara.”

“We had talked to our children before this and let them know we wanted to adopt someone and bring somebody into our relationship. Our children have been very supportive of this. They have understood,” Benno said.
Sierra says that there are zero problems with jealousy.

“I’m not jealous that the children are not biologically related to me at all. Just because I didn’t birth them doesn’t mean I can’t love them and they can’t love me. That doesn’t hinder my love at all for them,” she said. “There is really not jealousy in our relationship. Sometimes we have a hard time communicating because there are three people instead of two, but we always work through it.”
Which Kaiser will marry Kuntz has yet to be decided. The divorce will go through later this year.
