Shot on location in some cheap Brazilian hotel, Boo-Yow 10 is all about South American slit. This is good, as 1) Brazilians have more than their fair share of booty, and 2) the performers glisten with tropical sweat. Sorry to say, the action equals neither the heat of the climate nor the scorching potential. Though the girls of all five scenes are young and hot, only two scenes really get rocking. It's the tight and tanned number in the last scene - a threesome - that's a real firecracker.

The whole production is a bit ghetto. The camera tends to sit only in one place, while the girls are also eerily silent. (No groans or grunts-nothing.) One gets the impression that they're suffering through the session rather than getting off. The exception is again the aforementioned ménage a trois. That screamer saves the whole tape.
