The lab table against Mina Lasky's naked back offered her no relief.

Her breath rasped harshly. She sucked in each chest-full of cold air, pulling it in until she thought her lungs would burst, until they stung. It raced back through her body, up her dry throat, and escaped from parted lips. The cold touched her, but she was powerless to cover herself.

Her shoulder blades ached as the delicate bones jammed the unforgiving surface. Her legs had been spread wide, and even her tailbone had grown numb from the pressure of the cool table. But they were secondary concerns. She writhed and shivered more from anticipation than from cold or discomfort.

God, would they begin soon?

Behind the blindfold, she blinked against the black satin fabric as though she could stare through it, capture the light and watch them as they watched her.

Mina licked her lips. "Please," she begged.

"This is part of the experience you agreed to. Are you asking to be freed?"

Dr. Derek Link's velvety voice soothed her. Under normal circumstances, it lit her blood with lust.

Every year for his advanced class, Human Physiology: The Sexual Being, he asked for volunteers. He promised their satisfaction in return for the use of their bodies as scientific vessels. And Mina had always wished she had the courage to sign up for the lab experiment.

This time, she'd done it.

If it meant having the hungry gaze of Derek Link on her body, meant having him satisfy her burning fantasy to fuck him wiped from her mind, she'd do just about anything.

With her eyes covered and her face obscured, no one but Dr. Link knew the identity of their experiment subject. Good thing, too, because her credibility in the University would be a flash in the pan if the students knew who was really on their lab table. No one expected the reserved Chemistry doctor to bare her body for all to see, or allow herself to be tied down for a class on the sexual stimulation of the female organism.

It sounded so technical, but the reality was she hadn't been able to get past the way their eyes met when she passed Dr. Link in the hall, or the way his long fingers wrapped around the lecture podium. It was in his thick wrists and corded arms, his jean-clad thighs and tight-ass walk. She needed only to hear the sound of his voice, like melted sex, to instantly moisten her panties with lust.

Science should have been her noble reason for signing up. In truth, it was her inability to think of anything other than what it would feel like to have his cock raging hard and sharp against her womb. She'd bet a year's salary he'd vibrate her clit with a well-aimed thrust, and if he so much as huffed near her pussy, she'd come.

"No," she breathed.

"We'll proceed at my leisure."

"I'm cold," she told him.

"I can see that," he answered, a chuckle warming his voice.

It was all she had to hang onto. The voice, more tangible than her own skin, was warm enough to make her wish he'd lay the honeyed tones over her bared body, easing the prick of winter's chill against her nipples and spread pussy.

The dryer her mouth got, the more wet the prolonged wait made her cunt. It seeped. It was foolish to think he didn't notice. The direction of his voice put him over her, between her widespread legs.

She'd lost track of time, and though she knew it wasn't only Dr. Link standing over her--she had signed the consent form for several others to witness her arousal--she heard none of their voices. Just their breath, nearly as ragged as her own, as she waited for the experiment to begin.

The wind picked up, biting into her flesh. Mina strained against the bonds that held her wrists together high above her head. She tried to bend her knees, to bring them together as the winter air all but froze the cream leaking from her hot pussy.

She moaned softly.

"Watch her. See what her body is doing. The mere occurrence of being restrained and vulnerable has excited her," Dr. Link said.

"Couldn't the nipple constriction be from the cold?" a nameless student asked.

"It could. But lean down and breathe warm air on it. Don't touch her in any other way."

She heard the shuffling, felt the presence of someone leaning close to her skin from the warmth that radiated off him. Hot breath bathed her right breast. Unbidden, she arched toward it.
