She probably was at her peak in the Taboo series. The voyeur scene where she washes, creams her body and dresses in lingerie is probably one of the most erotic scenes in all porn because of her exquisite body and natural eroticism. I have wanked myself dry for decades over that scene.
Kay Parker could have gone on and on in the business, but had the good sense to retire while still at the peak of her eroticism and never returned to performing. She was the most voluptuous porn star of all time with a natural eroticism and genuine sex appetite.
What a lousy way for Kay Parker's porn career to end: The scene with boring Billy Dee & an impotent R Bolla is from her last movie, "Lorelei". She's as fabulous as ever, but what a couple of limp dicks they gave her to work with!
