The teenager has been dating her 39-year-old dad for two years, after going for 12 years without seeing him.
"He spoiled me rotten"
Speaking with New York magazine The Science Of Us, she explained that her parents had her when they were teenagers after conceiving her on their prom night.
Their relationship didn't work out and, while her dad wasn't around when she was born, he did play a part in her life until she was 5-years-old.
She explained: "He spoiled me rotten.
"We'd sit in the yard blowing bubbles together, and he took me to the zoo where he bought me a stuffed animal that I kept until I was 16."
Her dad emailed to get back in touch when she was 15-years-old and the pair began to message each other back and forth for two years.
When she finally met up with him in person, she was 17-years-old - and was shocked by her feelings towards him.
She explained: "It was so weird and confusing. I was seeing my dad for the first time in forever but it was also like, He's so good-looking! And then I was like, What the hell are you thinking? What is wrong with you?
"I saw him as my dad but then also part of me was like, I'm meeting this guy who I have been talking to over the internet and really connecting with and I find him attractive."
"What the hell are you thinking? What is wrong with you?"
She stayed at her dad's house for several days and, while he began by sleeping on the couch as she slept on the floor, over the next few nights he wound up lying on the floor with her.
And then, one night, they finally gave in to their feelings.
"We discussed whether it was wrong and then we kissed. And then we made out, and then we made love for the first time," she said.
"That was when I lost my virginity."
The teen continued: "I told him I wanted him to be the first person I made love to.
"It was insanely sensual. It lasted for about an hour and there was a lot of foreplay. We both had orgasms.
"We are so similar so it's so easy to sexually please each other."
Apparently her father's (now ex) girlfriend heard them making love through the bedroom floor, but was able to get past that and now they are "like a little family".
"We are so similar so it's so easy to sexually please each other"
The teen plans to marry her father at an alternative wedding, with a black and purple colour scheme, and is planning on having children with him.
She said: "Everybody thinks that kids born in incestuous relationships will definitely have genetic problems, but that's not true.
"That happens when there's years of inbreeding, like with the royal family."
She finished: "Incest has been around as long as humans have. Everybody just needs to deal with it as long as nobody is getting hurt or getting pressured or forced."
