Chapter Three: Graduating Mary
Mary was standing on a small dais in the middle of the dimly lit room. She was wearing a pair of tight leather shorts, spiked heels, and a black leather collar around her neck, and nothing else. The nipples of her small firm tits were rock hard and stood straight out, her lips were moist and slightly parted as she breathed in and out through her mouth in short, excited breaths. Her long, black hair hung straight down her back, and her skin glowed with a golden undertone in the light of several small spotlights overhead that were angled down on her body. Along with the hair and exotic dark eyes, her skin tone was a legacy from her Vietnamese grandmother. The sultry look in those half-closed eyes spoke of profound sexual arousal. Occasionally the muscles in her buttocks would clench, and each time a shudder of pleasure ran through her firm, slender body. Every time this display would be followed by a tightening of the muscles in her thighs as she squirmed, trying to squeeze her long legs together to put some sorely needed pressure on her pussy, but for easily discernible reasons, she remained frustrated.
This obvious reason for her frustration was the restraints around her wrists and ankles. Padded but solid leather cuffs encircled her wrists, fine but equally solid steel chains running from the cuffs up to a pair of massive eyelet screws embedded in the solid oak beam that ran the length of the room. The 22-year old woman's legs were secured by similar leather manacles, bolted directly into the wooden dais on which she was standing. The net effect of this was that Mary was standing in a spread-eagle position, hands above her head and legs apart, incapable of any movement beyond squirming.
She had been standing like that for over two hours. The room was warm, so she wasn't cold, but her legs were tired and her arms had long since lost all feeling from being extended over her head for so long. Still, Mary wouldn't dream of complaining. Mistress had said that she would remain there until she came back, and Mistress' wish was Mary's command. She had no idea if Mistress had left the house on some errand or if she was still there, but that wasn't important. The only thing in Mary's mind was the sweet, throbbing ache between her legs and buttocks, and the fact that she knew that when Mistress returned, she would allow Mary release from her excitement. If, that was, she felt Mary had behaved herself in her absence.
Mary was squirming in silent frustration as the door to the room opened, and a woman stepped through. The newcomer was tall, with long blonde hair piled up on her head. Her eyes were a cold blue, her face finely chiselled with a patrician look, vaulted forehead and high cheekbones, a straight nose and full lips. She was dressed in what looked like a man's suit, with shirt, necktie, pants and a jacket, but clearly tailored to show off her spectacular figure to maximum effect. The woman had long legs, round hips, a firm arse and a pair of impressive breasts that strained against the jacket.
The blonde woman closed the door behind her, then walked across the floor towards Mary, her hips swaying provocatively. The look on Mary's face was hovering somewhere between adoration and downright worship.
"I'm back," the blonde said in a sultry voice. "Have you missed me, Mary?"
"Yes, Mistress," Mary moaned. Her breathing had quickened even more just by watching the other woman enter the room.
"That's good," Mistress murmured as she reached out and cupped Mary's face in one hand. Mary closed her eyes, savouring the caress while inhaling deeply of Mistress' scent. The blonde's other hand was rubbing Mary's belly, before moving further down across her leather-clad hip and around to cup one arsecheek. Stepping in close, Mistress pressed her body against Mary's and kissed her fully on the lips. Mary's mouth opened eagerly, and the two women's tongues engaged in a by now familiar dance.
Mary felt Mistress' large breasts press against hers, and whimpered into the other woman's mouth as she tried in vain to grind her hips against Mistress', but the blonde woman kept just enough distance between them that Mary couldn't reach her. She gave Mary's arse a last playful squeeze, then pulled her lips away.
"How is your bum doing, then?" Mistress asked.
"It's fine, Mistress," Mary murmured, looking down and blushing slightly.
"Let's have a look, shall we?" Mistress proposed.
Without waiting for a reply, she reached down to the fly of Mary's leather hot pants, opening it with experienced fingers. With the fly open, Mistress slipped a hand inside, palm up, and caressed Mary's dripping wet pussy. "Are you wet for me, sweetie?" she whispered in Mary's ear.
"Y... yes, Mis... Mistress," Mary panted, having obvious trouble with her voice. She was so excited that the feeling of Mistress' fingers on her pussy was very nearly enough to give her an orgasm. Mistress wiggled her hand deeper down inside the tight shorts, pushing a long finger up Mary's pussy. Mary gasped and ground her pussy against the groping hand, desperate for release, but Mistress smiled sweetly and withdrew first her finger and then her hand. Ignoring Mary's pleading eye, she held her hand up in front of her face, the extended finger wet with Mary's juices. Mistress held her finger close to Mary's lips, and the bound brunette stretched her neck and opened her mouth, eager to taste herself from Mistress' finger. The blonde held her finger just out of reach, and after teasing Mary for another second or two, she put the wet digit in her own mouth, sucking it clean. Mary whimpered in helpless arousal as Mistress slowly pulled her finger out of her mouth.
Then the tall blonde cupped Mary's breasts in her hands, kneading them gently, teasing the erect nipples by scratching her long nails over them. Mary moaned with pleasure, sagging in her restraints as her knees buckled. Mistress stepped close again, kissing her deeply as both her hands wandered around to Mary's back, trailing down until she slipped both hands inside Mary's shorts, cupping her buttocks. Using the back of her hands, Mistress pushed the tight leather garment down Mary's arse, over the swell of her taut buttocks and down to the top of her thighs.
Mistress' fingers slid between the cheeks of Mary's arse, moving downwards in the smooth, hairless crack.
And stopped as they touched a piece of metal between Mary's buttocks.
Mistress put her finger on the square piece of plastic and wiggled it gently around. Mary moaned in response, a plaintive, begging sound.
"Feels good, doesn't it?" Mistress whispered.
"Oh, yes, Mistress," Mary groaned. "Please... please..." She was almost sobbing.
Two days previously Mistress had inserted a butt plug in Mary's arse for the first time, and since then she'd been wearing one every waking hour. They'd started out small, barely larger than a finger, and had increased in size. The one she had in her now was nice and thick, and Mary could feel it shift slightly inside her with every step she took, every time she sat or stood or shifted her hips even slightly. The sensation was driving her crazy, keeping her in a state of perpetual arousal.
