Wish "Having fun?" asked Maria. A smile crept on her face as she looked down at her helpless captive, Susan. She was squirming around for all she was worth, getting herself worked up into a frenzy again. Dressed only in a white string bikini that Maria had picked out for her, the sight of her alternating between pressing her body against the bed and writhing around, a pleading look in her eyes, was a potent aphrodisiac. Susan's wrists and ankles were encased in cuffs that were joined together behind her back using a single padlock. The hogtie forced her to arch her back, as if she were proudly displaying her body for her lover. Her luscious lips were wrapped around a bright pink ball gag held in place by a padlocked head harness. Her hair was tied in pigtails, partly because of the harness, and partly so her hair didn't get in the way, but mainly because Maria thought it made her look irresistibly cute. Already puddles of her drool had formed in the various places she had managed to hold her head above the bed or rest it face-down. Susan cried out a muffled protest, a sort of whine that turned into helpless sobbing. Maria hadn't seen her this frustrated in weeks. She felt her labia tingling with arousal. Sitting down on the bed next to her helpless captive, Maria took off her spaghetti top, then unzipped her boots and slid off her miniskirt, leaving only her underwear - a sheer bra, thong, suspenders and stockings. Finally, she slid the thong off. Maria lay down on the bed next to Susan. Already she could smell the scent of her lover's arousal. "You don't mind me joining you, do you?" Susan let out another half-whine, half-sob. "It's just you look so tempting like that, you're getting me hot." Maria caressed her own body, leaving her captive alone. She slid her hands up and down herself until caressing turned into groping. She squeezed her breasts and clasped her crotch, increasing her desire further. Maria glanced at her lover. "Want a hand?" she asked, idly caressing Susan's body with her gentle touch, starting at her navel and ending with the subtle tickling of a spandex covered nipple. Susan nodded frantically as she hummed loudly through her gag. "Oh, that's right," said Maria, pretending to suddenly remember Susan's request to her the night before. "You said you wanted to be tied and teased, didn't you? Are you sure I can't change your mind?" Susan nodded frantically as she tried to move her body towards Maria's, squirming around as she inched herself closer and closer to her lover. She tried to convey how frustrated she was, but although her muffled noises made her burning desire clear enough, Maria was still playing dumb. "I guess not," said Maria. "After all, you were pretty specific about me not caving in and untying you no matter how frustrated you looked. And you do look pretty frustrated." She caressed her own labia, enjoying the sensation. "I'll just have some fun by myself then, hon," she informed Susan. "Try not to distract me, OK?" Maria licked her finger before plunging it deeply inside herself, exploring her most intimate region. She slid her finger out and in again, slowly building up her rhythm. It was no use, though - Susan had managed to crawl up to her, and had started nuzzling her cheek with her own. Sighing, Maria withdrew her finger, licked it clean, and slid off the bed. "I warned you," said Maria sternly. Susan looked up at her with puppy-dog eyes and whined pathetically, but it was too late. The damage had been done; Maria's flow had been disturbed. She walked over to their blanket box and retrieved a pair of nipple clamps. She knew how much Susan disliked them. Susan's eyes widened in horror as she saw Maria approaching her with the clamps. She shook her head frantically, humming short bursts of protest one after the other. "You should have thought of that before nuzzling up to me," suggested Maria as she untied Susan's top behind her back and neck. She watched it fall onto the bed as Susan writhed around, trying to wriggle away. Maria savoured the sight of her squirming lover for a while, partly to increase Susan's fear while she put off the inevitable, but mainly because she was getting her arousal back, watching her lover's breasts swaying back and forth. Once she'd grown tired of watching her partner squirming, Maria finally applied the clamps, carefully pinching one nipple at a time, gently releasing her grip on the clamp as it fastened around her naked, helpless breasts. Susan practically screamed into her gag. Maria had never seen her so alive. She playfully tugged at the chain before letting it fall onto her partner's chest. "If you can calm down long enough to let me masturbate in peace," Maria advised, "I'll take those nipple clamps off you once I've finished." She watched her partner taking great effort to control herself, her breathing gradually slowing down until her breasts were proudly thrust forwards with each deep breath. "That's better." Maria affectionately cupped one of Susan's breasts in her hand for a while. When she finally withdrew her hand, Susan only let out a faint whimper. This time, Maria wasn't interrupted by Susan. She slowly built her rhythm back up, taking her time. Looking at her helpless captive for inspiration, she started to rub her clit. She moved her finger slowly at first, in gentle little strokes, but soon built up her pace until her hand was a blur, and her breathing became short and erratic. Finally, she reached a loud and satisfying orgasm. After lying down contentedly for a minute, Maria jumped back off the bed and put her clothes back on before turning around to glance once more at her lover. She firmly groped Susan's breasts with both hands, savouring their feel, before gently releasing her nipples from the clamps. Susan briefly gasped in pain, or perhaps intense relief, with each one. "I'm going to watch TV for a bit now, hon," informed Maria as she strolled across the room to the door. Susan squirmed around frantically, making desperate muffled protests as she tried to turn around and face her lover. "Oh, you want to have some fun too?" asked Maria innocently. Susan nodded. Maria went back to the blanket box, and after a bit of rummaging around, walked back over to her captive. "Here you go." She threw one of Susan's vibrators onto the bed next to her. "If you try hard enough, you might even manage to use it for a while before I come back in half an hour or so." Susan tried to protest again, but she squirmed towards the vibrator, showing Maria her true desire. "Actually, make that about an hour," decided Maria. She ignored her lover's pleading moans as she strolled out of the room.
