Jacky O

German adult model Jacky O was born in Berlin, where she also got her start in the industry. She began her career in 2008 at around 23 years old and was active for four years, until 2012. During that time, she became known for her natural, unenhanced figure, which she complemented with pierced nipples. Her blonde hair and blue eyes (implied) added to her look, while her measurements of 36–28–34 and a 36DD bra cup size made her stand out.

Jacky's performances included solo work featuring full nudity, masturbation, and dildo scenes. She embraced her chubby body type, which contrasted with the more athletic builds common in the industry. At 5'7" and 152 lbs, she brought a relatable, curvy presence to her work. Since retiring in 2012, she has maintained a private life, leaving fans with a catalog of her earlier performances.
