As the name promises, pendulous mammaries abound, put into entertaining context in this yarn about an all-female tribe blessed with a stone that augments breast size.

Four male explorers with their eyes on that prize encounter the Mamazons engaged in a Sapphic orgy orchestrated by their queen. Naturally, the tables are turned and the men end up behind bamboo bars, their manhood eyed hungrily by their curious, concupiscent captors. One by one (sometimes two by two), they become playthings as the tribe explores its new heterosexual horizons.

Overall, the production hits just the right ratio of plot to porn, and the sturdy female stars carry their ample racks with grace. These Mamazons supply a spirit of adventure that melds with the attractive outdoor sets and jungle soundtrack—particularly Alexis Silver as the imperious, regal queen.
