Robin had never said "no" to a challenge. Immediately presented with the firm hand of an experienced Dominant, she felt herself slipping into that hypnotic state of submission, where she would have been easily persuaded to act in any fashion that Adam ordered; for the moment, he was the Dominant, a teacher to her boyfriend and a Don Juan to her. Robin felt completely relaxed with her loss of control, and it was this final stage of limpness that caused her to feebly smile and moan a very gentle, almost inaudible, "Mmmhm..." She had barely noticed that she was naked by the time she came to it, and once hogtied and in a vulnerable state, felt incredibly weightless. She was deep in subspace, now that her boyfriend, her love, was watching her be humiliated by this cruel stranger; it was a fantasy come to life.
When Adam lifted her chin, Robin knew better than to look him directly in the eyes. She kept them lowered submissively, like a dog to its alpha, and moaned a gurgling, soft "Uhm!" until the crack of the whip landed on her butt. She flinched, crying out in pain and feeling a knot in her throat begin to form. Tears had begun forming, but the moment he put the first padlock onto the chain, she began crying openly; tears streamed down her face, barely easing the excrutiating pain of the padlocks to the clover clamps that pinched her nipples, feeling more like needles than rubber-tipped clamps.
"Uhh, err... Mercy!" she begged, taking care to articulate the last word as much as possible, less so with the "Please, Sir!" preceeding it. She was ever so close to calling red, but the endorphins rushing through her body left her with a higher pain tolerance than she had ever had before. The young woman had begun to sob, gagging on the ball in her mouth as she attempted to breathe through her mouth to lessen the sharp pain. Robin finally raised her chin to look at Adam, wide-eyed and helplessly, with her eyemakeup sketching black lines down her face from her tears.
Adam smirked. "Mercy, eh?" he mused, immediately lifting a padlock from the chain, tossing it aside and seeing Robin's immediate response of a gargled "Thank you". Though he was having ever so much fun torturing her, he also knew that she would have called "red" if she weren't too deeply into subspace. So, he removed the padlocks, leaving the clover clamps on her nipples- and to Robin, after feeling so much pain, the nipple clamps felt like nothing. He walked to behind her, undoing her legs so that she could stand, then stepping back about five feet. "Face the wall," grunted the man, and as she turned with much difficulty (her feet barely touched the ground, so she was left swinging just a bit), a loud snap in the air sounded and the tip of the bullwhip bit her on her back, leaving a fresh, scarlet mark and a cry of "Mmmphm!" from the whip's target. He stretched out his neck, then cracked his knuckles, aiming for the soft, vulnerable spot on the backs of her thighs, then swung again, hitting instead under her ass and just barely missing the lips of her pussy.
"Hear that, Tommy?" Adam jeered, raising his whip and cracking it again, lower on her back and dangerously close to her kidneys. "That's the sound your girlfriend makes when she's been pleasured by a real man." He laughed, setting aside his whip and walking to her, grabbing her by the throat and smacking her butt with his hand, firmly. Instead of pulling away, however, he slid his hand down to her womanhood and slid in a finger, checking for wetness; Robin was perfectly moist, and his fingers made wet sounds as he coaxed them between her labia, his middle finger thrusting inside of her before adding another finger. "You've been a very good pain slut for me," he groaned in her ear quietly. "But let's see how much you can take with your boyfriend watching."
Robin whimpered through the gag, long strands of drool forming around her pert lips and leaking onto her collarbones. "Mmank ooh er," she attempted, given the difficulty of saying "Thank you, Sir". She desperately wanted Thomas's gentleness after Adam's harshness, but she also wanted to please- wait... where /was/ Thomas?
