Tammy Underwood, assistant of renowned cryptozoologist Dr. Benson Wackerly, has been left alone in the lab with orders to keep an eye on a strange new monster they’ve captured. It seems like an easy enough job…till the monster enters a state of intense arousal that looks likely to prove fatal if the massive, incredibly well-hung creature can’t find a female to mate with. With no way to contact her boss, and unable to watch the poor thing suffer, young Tammy decides to offer it the only female available: herself.
