(This was originally filmed as a custom video) Fiona wakes up in a strange, laboratory-like room. She is alone and strapped to a table, with her wrists and ankles restrained tightly. As she groggily becomes aware of her surroundings and realises she is trapped, panic begins to set in. Just as she notices a camera placed directly above her, a robotic voice informs her that she is test subject 319 in an experiment. Fiona struggles violently against the restraints as the voice continues; 'Protocol: Variability in sexual stimulation'. Fiona watches in horror one stimulating machine is attached to her clit, and another inserted inside her. She is then subjected to a repeating process of stimulation to the point of almost orgasm, followed immediately by intense and violent electric shocks. She is barely given time to recover before the sexual stimulation starts again each round, and the intensity of both the stimulation and the shocks only get stronger each time. By the time Fiona is finally granted an orgasm she is a whimpering, broken mess - and after finally cumming extremely hard, all she can do is lay there, twitching and moaning!
