Mousy biology professor Rainahh has developed an aphrodisiac for endangered species that is much more effective than she thought. Not a very original premise, but director Horny Henry has used it to frame five first-rate sex scenes, all with anal action, as advertised.

The scenes are all well shot and well-edited, and the performers frequently lose themselves in pleasure. In order to test the drug, Rainahh heads down to the local pub and takes on Ian Daniels and Guy DiSilva in a very hot d.p. Randi Storm and Brian Surewood work well together, as do Kyle Stone and Rainahh in the finisher.

There's not a bad scene in the lot. Recommended.
