In the clips, she dresses in sexy clothing and dirty talks towards the camera.
"I'm proper English, I'm a heavy tea drinker, and I'm clumsy," Olivia said
"They love my accent here in the USA. Fans are always asking for custom videos of me, just talking."
And added: "What can I say, the yank perverts can't get enough – maybe one day I'll branch out into audio stories."
Her family in the UK are on board with Olivia's choice of profession – so much so that her mum wants some of the action, too.
She said: "Family and friends love what I do – especially my female family members.
And admitted: "They want to get involved too! My mum is most supportive of all … we're talking about starting a mum-and-daughter fan page."
While she's content doing what she's doing for now, Olivia hasn't ruled out going mainstream in the future.
She said: "For now, I like working for myself, but I wouldn't rule out mainstream erotic films. I just don't want to grow old gracefully – like, at all!"
Despite her success with men, Olivia, a self-described "freak in the sheets", is currently single – and is happy.
She describes herself as "busty, curvy and curly" and "a true, juicy burst of tropical delight".
But the "downside of being a hot girl", she said, is that blokes "just want to have sex right away".
She enjoys getting to know them first over dinner.
