British porn network Television X has made quite a few porn parodies, often targetting British subjects. Among their most recent and most risky endeavors is The Iron Lady Garden, introduced in this SFW YouTube trailer.
That’s Brit MILF pornstar Rebecca More as Not Margaret Thatcher, or Not Meryl Streep depending on how you look at it.
Television X titles generally appear first on their own website and TV channel, then later make it to DVD and VoD. We’re still waiting for The Iron Lady Garden to become available on this side of the pond.
