Meet Rini, a bisexual Asian researcher with a passion for creepy crawlies of all descriptions, and Rini works with Carol, a blonde who isn't quite as enthusiastic about the subjects of their study... in fact most of them give her the shudders! So imagine how she reacts when a leech attaches itself to her breast, but Rini isn't repulsed, she is turned on to watch it feeding, so much so that she begins to develop a kinky and very taboo plan!
