Chapter 2 - testing

She looks at Alma, her eyes filled with a combination of fear, need, and dread. "I know," says Alma, "you don't have to ask. When I've finished calibrating I'll begin the test with full penetration, and since you're cooperating I'll make sure you're satisfied. It will be the last time you cum from sexual stimulation. I've got you pretty tightly dialed in, and I can tell you, you're going to LOVE chocolate ice cream when I'm done with you!"

Gina's panting body pauses for a moment in panic, her conscious mind for a few seconds managing to exert control again over her body and mind. She feels her will to resist slipping away, her body and mind beginning to embrace the tendrils of stimulation and measurement of the relentless computer. She is aware that the effort of denying the automated machine the ability to play her sexual responses like a musical instrument takes all of her focused attention. Her sweat covered body and the animal parts of her brain beg her to stop resisting, to allow herself to enjoy the most intensely pleasurable sensations she has ever felt.

Suddenly, it is over, and Gina collapses, her willpower overcome by a desperate for more stimulation, her body in a frenzy of sexual need. "Don't worry Gina," whispers Alma, as she removes the vaginal stimulator from Gina's wet and swollen pussy, "you'll get what you need." Gina trembles with shame and need as Alma removes the belt from her waist, allowing her some room to flex her hips. She produces a large ribbed dildo from under the table, mounting it on a mechanical armature, and positions it against Gina's swollen vulva. As Gina instinctively moves her body forward, pushing her hips against the dildo, she feels its pressure at the tight opening to her vagina. As she pushes frantically against it, her restrained body unable to cause it to penetrate her, it begin to oscillate rapidly, transmitting electrifying vibrations into Gina's hungry sex. Frustrated, she shifts her body as much as she can, her wrist restraints painfully tight, bucking wildly, but unable to penetrate herself with the vibrating cock. The tip of the cock presses tantalizingly against the opening to Gina's vagina, and aching with need she looks at Alma with humiliation and desperation in her eyes. Alma nods, smiling, and releases Gina's wrist restraints.

Shocked to feel her hands free, Gina thinks momentarily of trying to release herself from the table, pull the wires and stimulators from her body, and overpower Alma, but in an instant she knows that she will not, the arousal and need in her body is too great for her to do anything but obey her most primal urges, and she props her body slightly, pushing herself forward as she throws her head back in ecstasy and satisfaction. She bends her knees, her buttocks moving forward on the table, her hips bringing her vulva forward, impaling her slowly on the vibrating penis.

Alma steps back, smiling as she glances at the computer console for confirmation of what she can already see. Gina's conscious mind is completely helpless, her body surrendered to its most basic primitive stimulus and response. Her upper body, no longer physically restrained, is propping herself up by her wrists and arms, her hips elevated just enough to be able to buck backwards and forwards, ***ing herself on the vibrating artificial cock. No longer needing encouragement, Gina is panting and moaning with the stimulation on her clitoris, the strong massage on her breasts, and the sense of fullness in her dilated pussy.

Alma recognizes that the end is near as Gina's vocalizations become louder and more intense - crying out for release from the crescendo of sexual stimulation, more intense than anything she has ever experienced before. She begins to cry out incoherently.

"Please! Please!" She shouts. "I'm so close! Please let me cum, I need it so badly - please! That is so good! I've never felt like this! OH! OH NO! Oh I'm cuming!" Gina's body thrashes on the table as she thrusts wildly on the vibrating cock, her spine arched in tense pleasure, then, in a final spasm of need she pushes with all her might, forcing her clitoris against the powerful vibrator, fits of muscle contractions wracking her body as she flops and tenses on the table in an orgasm that shakes her body leaving her screaming in pleasure.

As Gina lays panting in recovery, her eyes closed, Alma approaches her with a small face mask, placing the mask over her mouth and nose. As Gina pants and moans Alma is not even sure she notices that she is breathing in a powerful anesthetic. In seconds, Gina is deeply unconscious, and, with the information on her responses that Alma has collected, ready for her neurosurgery.
