onto the table. He attached sensors to her chest and neck to monitor her temperature, heart rate and blood pressure. She leaned back but, when he moved to stand between the stirrups, her legs instinctively clamped closed. He waited patiently until she summoned the courage to lift one leg and place her foot in the metal support.
She froze when his gaze went straight to her pussy, but his academic mask was firmly in place. Suddenly, Tressa realised why she was so hesitant. He’d gotten her horny. With all his seeming disinterest and absent-minded touches, he’d aroused her.
It didn’t make her feel any better. Now, she was embarrassed that he’d see.
When she didn’t move, he caught her other ankle and shifted her into position. Vulnerability made her squeeze her eyes closed. Her pussy was bare and fully visible, but this man wasn’t her doctor or her lover.
‘Slide down closer to the edge of the table,’ he instructed.
The move forced her legs wider open, but even that didn’t meet with his approval. He adjusted the stirrups until her knees were spread and her hips were tilted. The position made her defenceless, and her heart began pounding like a big bass drum.
‘I need to touch you now,’ he said. ‘Please relax.’
It was impossible to relax as his hands settled on her inner thighs. Her muscles tightened almost painfully, yet he paid no attention to her resistance. Using his thumbs, he smoothed out the lips of her pussy. ‘You’re wet. Have you been excited sexually earlier today or are you becoming aroused?’
Her breaths were coming hard. He was looking right into the depths of her, yet Marco unwillingly came to mind. ‘Both,’ she said in a strained voice.
He slid a finger into her. She was unprepared for the penetration, and the muscles of her lower back contracted reflexively. ‘Ooooh,’ she moaned as her feet pressed hard against the stirrups.
‘That’s good.’ The professor removed his finger and wiped it on a towel. ‘You need to be aroused for the experiment to be effective. It will reduce the amount of lubricant I have to use.’
Tressa’s fingers curled into the paper sheet beneath her. Arousal was one thing, but she was fighting to keep it under control. For some reason, she felt she needed to stay at his level, which was purely observatory and analytical.
‘I have one more measurement to take before we begin the actual test,’ Walton said as he tinkered around his desk. ‘I should warn you that you may experience some discomfort.’
Her eyes widened when she saw him pick up a long cylindrical object. ‘What is that?’
‘I need to measure your vagina. Today’s designers have come up with a wide array of orgasmic manipulators, but I wouldn’t want to hurt you. The measurements will help me choose the most appropriate device for your pleasure.’
‘Oh.’ The air seeped out of her lungs. His clinical language reinforced her need to stay controlled, but as she looked at the tool, she didn’t know if she could stay objective. ‘How does it work?’
He showed her the markings. ‘This will measure the length that you are comfortable taking.’
He showed her a switch at the base of the instrument. When pressed, the device expanded. ‘Obviously, this will determine the breadth. It can cause some discomfort, but our studies have shown that this can be a key factor for females to achieve orgasm.’
‘I understand,’ she said inanely. Size mattered.
Once again, the banal little man stepped between her legs. Her hips automatically tilted and he nodded with approval. He tested her wetness with a swipe of his finger and decided to avoid the lubricant entirely. She felt the blunt end of the tool press against her a moment before it was sliding into her.
The hard plastic went up, up, and up. ‘Oh! I didn’t … Oooooh!’
The smooth cylinder was touching her in places that had never been touched. She felt thoroughly impaled, and she squirmed until the professor placed a comforting hand on her tense thigh.
‘There are straps overhead if you need something to hold on to.’
Blindly, she reached upwards. Her fingers wrapped around the nylon straps, and the muscles in her arms flexed. With her legs splayed open, there wasn’t anywhere she could move. The hardness pushing into her made her want to move, though. Badly.
‘A little more … Yes, there.’ Walton leaned down and read the markings on the instrument sticking out of her opening. He picked up his pencil and carefully noted the measurement in his lab book. ‘Now this will be a little more intense.’
Tressa’s fingers turned white around the straps. God, she wanted to move. The professor, though, was still cool as a cucumber. ‘All right,’ she said with as much dignity as she could muster.
He flicked the switch, and the effects were devastating. She could feel the pressure increasing. It was as if a man’s cock was swelling inside her. Closing her eyes, she let herself enjoy the sensation. Almost immediately, Marco’s rugged face appeared.
She whimpered when her mind latched on to the fantasy and wouldn’t let go.
‘You’re doing well.’ The professor’s hand dropped onto her abdomen. With a firm touch, he tried to calm her.
She was too caught up in the erotic daydream to be soothed. Marco’s cock was deep inside her, and it was growing. Her hips surged off the table to take more of him.
‘Oh, my!’ Professor Walton tried to settle her, but she couldn’t stop writhing. Finally, he used his weight to pin her to the table and watched the diameter measurement increase. ‘Don’t fight it. Let yourself open. Yes, that will do fine.’
‘Move it,’ she begged. ‘Please, do me with it.’
‘Now, now. If you orgasm too soon, the experiment will be a failure.’
Tressa groaned as he reversed the motion of the tool and pulled it out of her. She felt empty. She needed something inside her. Her pussy was crying for it. ‘Professor, hurry.’
He seemed thrown by the sudden change in her demeanour. Drumming his fingers against his chin, he finally chose a strange-looking item from the nearby table. ‘I think this new manipulator will suit you. It’s an exciting innovation. The phallic module moves in a lateral fashion, thus simulating the thrusting motion of a man’s hips.’
She didn’t really care. She just wanted something, anything inside her.
‘With this option, an added feature is engaged. This doughnut-shaped structure will traverse the length of the phallus, giving added stimulation to the walls of your vagina.’
‘Please, Professor.’ All her carefully cultivated poise had left her. She was a woman dying to be screwed.
‘All right.’ The professor frowned as his carefully designed experiment threatened to go awry. ‘We’ll get started.’
Tressa felt no shyness when he assumed his position between the stirrups. Her hips lifted and her shoulders pressed hard against the table as she waited. The professor didn’t waste any time. He’d measured her carefully,
