Tyler And Berkley, Amateur Porn Stars Record Sex To Support Their Child

"I wanna be able to live a comfortable, happy life -- porn's givin it, so I'm gonna take it," says Tyler, 24, who did not want his last name revealed. He and his girlfriend Berkley, 21, make about $1,000 a week posting live sessions of them having sex online. Before they began recording sex for money, the couple had difficulty making ends meet.

Sometimes, though, they're interrupted by a baby monitor.

The couple says they need the cash that porn provides to support their 20-month-old daughter, to be responsible parents. "Our America With Lisa Ling," premieres Sunday night spotlighting Tyler, Berkley and their life in the amateur porn industry as parents. In a sneak peek of the show, Tyler tells Lisa Ling that if they hear a rustling through their baby monitor they will "sign out, go tend to her and usually come right back to work."

Though Tyler says that they just want to be a normal family, Ling raises the question "Is raising their daughter in the shadow of amateur porn truly normal?"

They hope that by the time their daughter is old enough to understand -- or wonder -- what her parents do for a living, that they won't be doing it anymore. At least not "seriously." Tyler's goal is to make enough money so that he can go to college, or learn a trade, so that they won't have to rely on porn for income.

CORRECTION: An earlier version of this article said that Tyler spoke to "Nightline." The couple's interview will air on "Our America With Lisa Ling" on Sunday October 16.
