My initial idea was to paint an old style Flemish portrait, but with a ballgag. The idea then evolved into painting a Voortrekker girl ('meisie'), with a ballgag. The suggestions and innuendos in this work are many, and I'll let you come up with those.
Ps: I visited five sex shops to no avail, and ultimately had to buy the ball gag online. I find this very strange, as I live in Cape Town.
Pps: Many thanks to the model. You know who you are.
