Jayna Oso was born in Malaysia and moved to Hawaii where she did most of her growing up. She settled eventually near Los Angeles, California and at 20 was working as a stripper. She was approached by a man in the club one evening who asked her if she had ever considered working in the porn business. She was curious about it and decided to give it a try and so began her career in adult movies.
One of her very first movie performances was for West Coast Productions and was called "Cute Exotic Girls 5" and was directed by Bubba G. in 2002. She appears in scene two and performs a hot blowjob and fuck scene, including even anal sex, capped with a facialcumshot like so many scenes are. Another early film was "There's Something About Jack 20" starring Jack Napier. It's one of her first interracial movies and she performs in scene two again but this time it's a threesome with female costar Honey Bunny and Jack.
Jayna says in an interview that once the camera starts rolling she just transforms into a pornstar who wants to fuck. She admits to having always loved the feeling of being naked and adding sex and cameras just makes it too hot to resist for her. She took home several awards during her career including the XRCO Superslut award in 2004. Her AVN award nominations for that year include Best Three-Way Sex Scene for the movie "The Voyeur 24", and Most Outrageous Sex Scene for her performance in the movie "Lewd Conduct 17." The following year saw her rake in several more nominations in the categories of Best Anal Sex Scene, Best Oral Sex Scene, Best Three-Way Sex Scene and finally Female Performer of the Year.
Jayna Oso is said to have retired from the adult movie industry in 2012 though she does perform in several compilation films that year, and one new release as well. Her fans hope it's just a short break and that Jayna gets back to performing in more hot adult movies before too much longer.
