The Estancia Series by Jonas

Back in the 1990's I purchased a series of BDSM novels called the 'The Estancia' written by Jonas and illustrated by Pan. The series comprised four titles, 'Estancia One to Estanica Three' and 'Slave Training at the Estancia'. It was a very well written tale about the subjugation of women and their training to become pleasure slaves for the benefit of their owners.

The series was published by Olympia Press and I wonder if anyone has seen or read any subsequent works by the author.
