Jayna Oso is a lean, luscious little lust bunny with ravenous sexual appetites that quickly got Jayna lots of attention from fans and adult movie makers alike. Jayna was born in Hawaii, She is the daughter of Asian and Irish parents, and she blossomed into a slender sex machine whose natural charm and winning smile never fail to allure and delight.

She quickly earned a reputation as a do-anything little strumpet who always brought her 'A' game to the table. Among Oso's best flicks is 'Full Anal Access,' which finds her in a searing session with Lex Steele, Erik Everhard and Michael S. , three of porn's most accomplished and hard-charging studs.
