  His thumb swiped over her clit, the perfect gentle, circling motion. Cali turned her head, pressing her face into her upper arm. Her breathing was heavy and hard as he thumbed her clit and hit her g-spot in sync.

  She focused on those soft feelings, letting the bondage fade to the background. She wasn’t ignoring the fact that she was helpless—after all, being bound, being helpless, was one of her kinks. But she ignored the exact method of her bondage—the humiliating exam table, her wantonly spread legs.

  For one blessed moment, in the darkness of her closed eyes, there was nothing but pleasure.

  Master Z withdrew his hand. She moaned in protest.

  And then tensed when she heard the clatter of the stool’s wheels as he resumed his seat between her legs.

  “As I said, I will do whatever I want to you.”

  Was he going to pretend that soft moment hadn’t just happened? Cali opened her eyes just enough to glance at him through her lashes. Had that been Master Z, or Zidan?

  She was an idiot for even thinking that way.

  Cali stared at the ceiling for a moment, then intentionally glanced down at herself. She was helpless and vulnerable, in the most lurid way possible. Now familiar embarrassment bit at her, heating her cheeks once more.

  Master Z picked up the dildo and shoved it into her pussy once more.

  This time when he showed off the toothbrush, she held her tongue though her leg and stomach muscles tensed.

  Master Z bent low, his dark head a foot from her pussy.

  The bristles of the toothbrush pressed against her clit. He was coming at it from the top—the toothbrush pressed against her clit hood. She could feel each bristle as a sharp, biting sensation. Already tensed muscles knotted tighter.

  He increased the pressure; she gritted her teeth to get through the pain.

  But it wasn’t pain…and it was. It was all those things, and none of them.

  “Your cunt likes this.” Master Z’s voice wouldn’t have been out of place in a doctor’s office.

  Cali’s embarrassment deepened once more to humiliation.

  “I’ll adjust the angle.”

  The toothbrush lifted for only a moment, and then it pressed against her clit. Coming from underneath, he went directly for her most sensitive flesh. The tips of the bristles bit into her, and her whole body jerked, the motion reflexive. His phone tumbled off her once more, but she didn’t notice.

  “Ass down.”

  Her butt hit the table.

  “You’re trying to close your knees. Spread them wider.”

  “Master Z, please, it’s…”

  “No, don’t stop talking. Tell me.”

  “It hurts.”

  “Just hurts?”

  She wanted to lie. She didn’t. “It doesn’t feel good, but I like it.”

  “Of course you do. Pretty slaves love having their clit tortured to please their master. Don’t they?”

  “Yes, Sir.”

  He removed the toothbrush only to put it back on her clit hood. He pressed down, and then started to rotate it in little circles.

  Cali screamed, and it wasn’t a scream of pain. He wasn’t scrubbing her skin with the toothbrush; rather he was massaging it with the circular motion while also stimulating her with the bite of the little stiff nylon bristles.

  And she spread her knees wide. Wide enough that her hips started to ache, begging him without words to hurt her, use her, more.

  “Your pussy is clenching nicely. A better response than when I used the probe on your clit.”

  Tears of embarrassment slid from the corners of her eyes, even as she strained towards him, wanting more.

  “I’m going to suggest your master apply nettles to your clit. They would burn when first applied, and then leave it swollen, sore, sensitive. I suspect that with an abused clit you’ll be not only perfectly obedient, but more accepting of degradation.”

  “No…” Cali sobbed. “I…I wouldn’t.”

  “Wouldn’t be obedient? I think you would. Wouldn’t like having nettles applied to your clit? Of course you wouldn’t. But it isn’t about what you enjoy, what you want, is it?”

  Cali couldn’t breathe. A spiky sharp feeling was forming low in her stomach. It was like an orgasm, but instead of smooth pleasure this was made of stimulation, embarrassment, and submission.

  “Master Z, I…”

  “Are you going to come from this, you slut?”

  Cali turned her face into her upper arm and nodded.

  “No. Look at me.”

  She didn’t want to, but he’d ordered her to. His gaze was dark with desire, but his lips were twisted in a smirk. He shoved the dildo, which had slid half out of her pussy, back into place, and the penetration was sweet and needed.

  “What kind of slut likes having her clit tortured with a toothbrush so much that she’s going to come from it? No. Look at me. I want you to feel this. See what you are.”

  “It’s too much,” she stammered, staring at his forehead, too embarrassed to meet his gaze.

  “It’s exactly enough. It’s what you need.” The smirk returned, and he kept working the toothbrush in small tight circles on her clit. “You need to be used. Played with. Spread wide, your pussy on display, not just for your master, but for anyone who wants a good look at this pretty cunt.”

  The orgasm grew, shards of pleasure lancing through her. She arched her back, keeping her hips and ass in place. Again and again he worked her clit. The pace relentless, as if he had all the time in the world to torment her.

  “You’re close to coming. I can see it in the way your pussy is clenching on the dildo.” Master Z’s neck was craned to the side, watching his phone screen which lay on the table beside her hip.

  “Yes, Sir.”

  “Tell me why you’re going to come from this.”

  “Because I’m…because I’m a masochist. A slut. A slave.” Instead of humiliation, she felt powerful and dirty in the best ways. “I need my pussy inspected and my clit tortured and—”

  The words froze in her throat as the orgasm exploded within her. Shards of sharp pleasure cut through her like shrapnel.

  Master Z dropped the toothbrush, his gloved finger swiping through her pussy up to her clit, circling it softly. Her orgasm stretched out, her body held at the pinnacle of pleasure by his gentle finger stroking her abused clit.

  Pleasure and pain from not just the physical but emotional impact of the scene created something she hadn’t felt since her first major BDSM scene.

  Zidan had been her top in that scene too.

  But nothing lasted forever, and the orgasm didn’t subside so much as crash down, like a massive wave breaking on the shore. She slumped back on the exam table, panting, shivering both in reaction and because a sheen of sweat covered her skin.

  Master Z rolled back, standing as he stripped off his gloves. Cali let her head thunk back, too tired to do more than wait for him to release her now that they were done.

  Instead, she heard a clinking sound. Before she could open her eyes to see what was making that noise, Master Z spoke.

  “Now for your ass.”

  Chapter 6

  Clear glass plugs, in graduated sizes, looked almost like objets d’art elegantly displayed on the metal tray. The smallest was no more than four inches from base to tip and only a bit thicker than a man’s finger at the widest part.

  From there they got bigger—not just taller, but wider. The neck of the largest one was three, or maybe even four, fingers thick. It was also ten inches long.

  Master Z picked the monster plug up, turning it so the light glinted off the smooth, slick surface. “Don’t worry, for this one I’ll turn you over on your knees.”

  “Thank you, Sir.” Habit was the source of that reply, because she was still shocked that the scene wasn’t done.

  He set the plug down, the base clinking against the metal.

  Air brushed her pussy—the room’s AC must have clicked on—and she shivered, which was
quickly followed by a residual pleasure spasm.

  Her clit was still throbbing, and her whole pussy felt swollen and tender.

  Master Z tapped two fingers on the tray near something she couldn’t quite see because of the angles. “I’ll also be testing your nipples.”

  “Master Z, I am…normally my master allows me breaks, after intense scenes.”

  He stared pointedly at her hands, waiting. No, damn it, she didn’t want to end the scene, but she wanted a minute to catch her breath, to work herself out of this intense, submissive, needy state.

  He smirked at her. “I am giving you a break…or at least your pretty cunt is getting a break.”

  Cali looked away, her jaw tight.

  “Ah, ah, ah.” He tapped the side of her face, her jaw. “Relax, slave. You have no right to grind your teeth and be mad at me for treating you like what you are.”

  Master Z’s thumb pressed against her lips. She opened her mouth, letting him shove his thumb inside, but didn’t suck or lick him.

  “You expect to be treated like a lover?” His voice was hard, cold. “You want time so you can give yourself a rest from thinking about the reality of being a slave… One who enjoys being used and abused.” Master Z reached up with his other hand and brushed his fingers over hers. The touch was gentle, almost questioning, and at odds with his words.

  He was reminding her that she had the option to use her safe word symbol.

  Cali curled her hands into fists, then spread her fingers wide, before relaxing them again.

  Unexpectedly, Master Z leaned down and kissed her hair.

  Then he slapped her breast, a sharp, punishing blow that startled a cry of pain from her.

  “Suck my thumb like it’s a cock,” he demanded. “I won’t allow this sullen passivity.”

  Cali closed her lips around him, her tongue swirling around the tip of his finger.

  “Better.”

  He palmed the breast he’d just slapped, kneading her with a firm touch that spoke of authority and dominion.

  “Are you sucking my finger because I ordered you to, or because you enjoy it? I think it started as one, but now…you enjoy sucking, don’t you?”

  Shame and arousal, both hot and thick, filled her. Cali nodded carefully.

  With a pop, he pulled his thumb from her mouth, rubbed his wet digit against the nipple he’d slapped, and stepped back.

  She was no longer thinking about breaks, or the fact that her legs were starting to ache. She would stay here, spread and open, for as long as he wanted. For as long as he was willing to keep and use her.

  Master Z sat between her legs, the now familiar sound of the wheels on concrete nearly drowning out the snap of him putting on a fresh set of gloves.

  Then he picked up the first plug and thumbed open a tube of lube.

  He rubbed the glossy lube over his index finger. “When was the last time you were used anally?”

  Her character—the beloved sex slave of a powerful man—would have answered yesterday, or even just that morning, since her master would use all her holes frequently.

  But for this question, she had to answer as herself. “Last month.”

  “And what did you take in your ass? Cock, plug?”

  “Anal beads. Smallish ones.”

  She didn’t know why she added anything about the size. It wasn’t like he was going to be gentle with her because of it. That thought made her pussy clench, and her still sensitive clit throb.

  Master Z chuckled, mirthless and just a little cruel. “Unfortunate, for you. But I promised your master I would test the limits of your ass, see exactly how big, and how thick, a plug you can take.”

  His index finger massaged her anus, little rubs and tiny amounts of pressure. She loved anal play because it did feel good. There were plenty of sensitive nerve endings on that puckered, soft ring of skin.

  The gentle massage made her relax back. She knew it wasn’t going to be pleasure, at least not this straightforward kind of pleasure, for long.

  “Your ass is lovely and sensitive, isn’t it?”

  “Yes, Sir.”

  “It’s going to hurt when I stretch you open, isn’t it?”

  She swallowed down the moan of longing. Oh how she wanted that pain. “Yes, Master Z.”

  “Good.”

  The cold tip of a plug nestled against her anus. Cali took shallow breaths and told herself to relax. She knew how to take something up the ass. Knew that tensing was the worst possible thing she could do. And yet her muscles tightened, her ass clenching closed.

  The first plug slid in, gentle and narrow. She relaxed as he settled it in place, breathing into the feeling of having her ass full.

  He left it there only a moment before withdrawing it more swiftly than was totally comfortable.

  Another plug took its place, and the tip felt wider than that of the last one, drawing the tension back into her muscles.

  “This plug is going in your ass, even if I have to force it.” His accent was deeper, richer, than it had been. “This one isn’t long, which means there isn’t much of a taper. It’s going to open you hard and fast. Even if you relax and accept it, it’s going to hurt.”

  Cali panted in fear-tinged desire.

  “I assure you if you make me force it, it will be worse.”

  “Y-yes, Sir.” Masochist that she was, part of her wanted to make him force it in, wanted to scream in pleasure-laced pain as he shoved it into her.

  “I want to use your ass, slave, and you’re making me work for it. I shouldn’t have to, should I?”

  “No, Sir.”

  “Because every one of your holes, every part of your body should be willing…eager, even…to be abused.”

  “Yes, Sir. I’m sorry.” Cali was nearly light-headed, she was so aroused by his words. The darkness in his voice.

  She relaxed her lower body, and when the pressure on her anus increased, she pushed out with her muscles. The tip of the plug jammed through the ring of muscle, into her, and she yelped.

  He hadn’t been lying when he said that it would hurt. It did, in the best possible way. It felt as blunt as if it were a cock pushing into her.

  She wished it was a cock. Wished it was Zidan’s cock.

  “Lovely.”

  Another shove opened her wider and Cali’s ass burned with pain, enough to make her pull at the manacles, chains clanking.

  “Hurt?” Master Z asked.

  “Yes, Sir.”

  “Good.” Another shove and the plug was in place, her sphincter closing around the neck.

  She felt full, and deeply submissive. Though anal among heterosexual couples was more common recently than it had been, it still carried a taboo. Anal plus bondage, plus his dark dominant words…it was almost a formula for how to make some women—or maybe it just worked on her—submissive.

  Master Z tugged the base of the plug, increasing the feeling of fullness. She fought her natural urge to try and expel it.

  “I’ll let you keep that in for a few minutes before I move up a size.”

  “Thank you, Sir.”

  He rumbled his approval at her words. “It’s a gift that I’m starting small and working my way up.” He stripped a lube-covered glove off one hand. “But I’ll need to find something to amuse myself while I wait.”

  Master Z spread the top of her labia, bending to look at her abused clit. Cali tensed, her pussy muscles tight.

  “Please, Sir,” she blurted out. “I’m afraid I’m so tender there that I wouldn’t be able to continue if you…”

  He glanced up, and her words trailed off. She dropped her gaze.

  “Topping from the bottom?” He clicked his tongue and then flicked her clit.

  Cali screamed through clenched teeth, her whole body throbbing in response to the intensity from that simple touch. When she could unclench her jaw, she said, “No, Sir. Not topping from the bottom. But… but as a slave, isn’t it my responsibility to communicate with my Master?”

 
Master Z laughed softly. “Too true. Very well. I will have to amuse myself elsewhere.”

  She wasn’t surprised to see the clamps he picked up from the tray, but she was surprised by the two short leather straps. Surprised because she didn’t know what he planned to do with them.

  His warm, soft mouth closed over one nipple, and it was the first time he’d used anything other than his hands on her bare skin. Cali arched her back, pressing her breast more firmly into his mouth, and he rewarded her with a gentle scrape of his teeth. This was pure pleasure, no pain to tint her enjoyment.

  He spent several minutes on that nipple, and when a particularly pleasurable swipe of his tongue made her body clench she felt the plug, that foreign and taboo stretching and fullness.

  “Lovely breasts,” he murmured against her skin. “You should be kept naked at all times, these pretty things always on display, and ready to be easily played with.”

  “I…I want that.” It wasn’t just the character she was playing who spoke.

  “I wouldn’t want to make your other nipple jealous.” With one last swipe of his tongue, he lifted his head.

  With brisk efficiency he grasped her nipple between two fingers, pulling gently, and then placed the clamp on the stretched skin. He adjusted the clamp, tightening it until she winced, then loosening it a bit.

  Master Z tapped the tip of her nipple with one finger. The clamp made an already vulnerable part of her anatomy more pronounced and accessible.

  He let the chain and second clamp dangle as he came around the exam table to her other side. Once more he sucked her nipple, laving it with his tongue, and using his teeth in only the most pleasurable of ways. Combined with the constant pressure from the clamp and the fullness from the plug, Cali was soon writhing under him—arching her back, rocking her hips forward and back.

  She managed to tilt her pelvis enough that the edge of the plug hit the exam table. Cali froze then did it again, the tiny motion enough to shift the plug inside her, which made all those sensitive nerve ending in her ass light up.
