The Men-Slaves of Cydonia

Commander Corry has managed to retrieve a vital piece of microtape from a space criminal named Johnson, when he, his prisoner and his wounded cadet, Happy, are captured by a tribe of beautiful Venusian amazons. The women have no use for males except as slaves and, when Corry refuses the office of slavemaster, the criminal, Johnson, is only too glad to accept. He uses his new-found freedom to abduct Happy to force Corry to tell him where he's hidden the microtape.
