This series, which has the possessive "Gia Darling's..." credit in the title but Third World Media hack Ed Hunter claiming director status instead, is standard TS action, but volume 9 offers some extras that make it a stand-out.
Primary thrill, at least for me, was seeing a beautiful and highly talented mainstream porn actress Renata Black thrust into the action in a threesome with the usual limp-wristed stud and an imposing big-dicked trans-female.
In addition, the lengthy program includes plenty of pegging and even a bit of kinky CBT action in one scene.
