When a graduate student volunteers for a clinical trial, she soon discovers the study is all about arousal—hers, to be exact, in the most intimate of settings. When she can't help but fantasize about the gorgeous female scientist, every lustful twinge shows up on the record. Three stories in one—from the first encounter to the explosive final experiment. Previously published in Change of Pace: Erotic Interludes (Bold Strokes Books, 2004); republished in Radical Encounters (Bold Strokes Books, 2009).
