Play Doctor: Dream Machine Part 18

Something inside her s.h.i.+fted. The artificial boundaries she'd drawn around her physical response dissolved.

Affection seeped into every nuance of their interaction. The circular current of their intimacy fed each other's desire, spiraling them both higher with every turn. Together, they became so much more than individuals.

"Whatever you need is what I want most."

With a feral, inhuman sound of longing, Kurt snagged the first carabineer dangling from a wire attached to one of the myriad leather loops encasing her body. He clipped it to a corresponding eyebolt, which had been welded onto the metal structure hanging above her head. Meticulously, he rechecked the security of the harness as he strung each cable until she imagined herself as a risque marionette.

When satisfied, he turned to her and asked, "Do you trust me?"

She nodded once.

A series of commands entered on the control panel initiated the rig's ascent. Slack disappeared from the wires. Spools gobbled the excess yardage until taut lines increased the pressure on her body as she struggled to maintain balance in her kneeling position.

"Relax. Let it take you."

Her legs unfolded beneath her when her upper body levitated from the ground. The motion of the s.h.i.+fting metal frame stretched her arms wide into Kurt's pre-programmed position. The pulleys retracted select cables until she resembled a T with her toes dangling inches off the cool, polished tile of the laboratory. Gravity sucked her against the padded restraints on her arms, around her rib cage and between her legs. The delicious pressure caused her to squirm, which triggered a lulling sway.

Though her bindings provided ample support, the air swirled across her exposed skin as she swung in shallow arcs. The instinctive fear skittering up her spine should have disconcerted her but it couldn't come close to overpowering the exhilaration saturating her. Her spirit soared like a crane cresting the Himalayas.

She squeezed her eyes shut against the overwhelming pleasure.

"Are you okay?" His immediate concern followed the gesture. "I won't let you fall."

"Oh, G.o.d. Yes." When she shuddered in the harness, it set off a tinkling of metal fasteners, transforming her into an erotic wind chime.

Lost in arousal, she basked in the glow of pleasure without a care for the outcome of the scenario. Nothing she did would alter what was about to happen because she couldn't change her nature. Or Kurt's.

The mechanism hummed as it elevated her. Her gradual ascent provided an opportunity to study every inch of his tensed body as it pa.s.sed before her eyes. The doctor observed the process, vigilant to test various wires and straps ensuring her comfortable safety. The motor paused. He stalked around her. His fingertips trailed across her skin, raising goose b.u.mps in their wake.

"Very nice." His hand dipped to pet the juncture of her thighs, tucked tight together. "But I want to see more of you."

He pressed another series of b.u.t.tons. Her wrists inclined as her legs separated until she hung in a flying X.

He stepped behind her.

"Turn your head to the right." She did as instructed but spun back after catching a glimpse of herself in the mirrored surface of the one-way gla.s.s on the opposite wall. The picture they made-her fair skin striped with dark leather, suspended in front of his imposing figure-blinded her with l.u.s.t. Kurt slapped her a.s.s hard enough to leave it stinging.

She wished he'd do it again.

"Focus. I want you to see what I see. Admire the play of light enhancing the lines and curves of your silhouette. You're spectacular." She peeked at the mirror but, instead of what he visualized, she only had eyes for him.

Rebecca's rapid, shallow breathing perpetuated the sway of her body in the harness. The motion drew his attention like a cat locked on a dangling string. His consumed stare inflated her confidence.

With one fingertip, he traced the furrow of her spine between the straps until it culminated in the cleft between her a.s.s cheeks. Her gasp reverberated through the examination room. Their eyes locked in the mirror- hers imploring, his possessive. Kurt rasped from behind her, "You've never had a man touch you here, have you, Becca?"

"Only you, Doctor." Her shy reply conflicted with her raging desire to experience his forbidden caress.

"We'll go as slow as I can manage, baby. We will do this, and you will like it. I promise." The smug a.s.surance held no boast. A virtuoso of the flesh, Kurt could strum her body until it sang.

She squirmed in a desperate attempt to apply friction to her aching core but, no matter how she thrashed, she couldn't squeeze her legs together or rub against the bonds hugging her inner thighs. The doctor chuckled at her futile effort as he circled her.

Once again situated before her, Kurt grasped her hips then tugged her closer until he could drag her nipple into the moist heat of his mouth. Instantly, it beaded beneath his ministrations. He flicked the sensitive tip with his tongue then nibbled it before releasing his hold on her waist.

The pressure on her breast increased tenfold. Only his teeth and lips fixed her at the shallow angle before her nipple slipped free from his light grip and she rocked away.

On the return arc, he seized her hips as he played with her other breast. She moaned when she watched his midnight hair brus.h.i.+ng her chest and his tongue glazing her pebbled nipple as he raised her. Then he sucked hard and let go. His teeth raked the plump flesh of her breast as she escaped once more.

He repeated the pattern, building a rhythm her body learned to antic.i.p.ate. The swinging motion mesmerized her. It gave her a moment to cool off before he boosted her higher again, each trip expanding his caresses to another exposed part of her body. Each touch was more intricate and inflammatory than the last.

When she expected his next wicked embrace, Kurt s.h.i.+fted. Reaching into his pocket, he selected a b.u.t.ton on the remote. The motor reengaged with a buzz. The wire attached to each leg cuff zipped through a pulley on the side of the suspension bar, drawing her appendages wider apart. Before she could adapt to the new position, she rose until her pelvis aligned with his.

"Enough playing, Becca. Time to get serious." Though he directed the words at her, she understood he'd scolded himself to stay on track. After all, she was helpless.

She heard the whiz of a cable unraveling a moment before she pitched forward. She shrieked, fearing she'd splatter on the floor in the next instant. Instead, Kurt steadied her with a broad hand on her shoulder, murmuring rea.s.surances.

Heart racing, she watched as the ground pivoted in front of her in a controlled descent. The cables connected to her upper arms and torso bands went slack while the lines attached to her thighs and knees contracted. As a result, she rotated forward. She stopped parallel to the yoga mat she'd kneeled on earlier as though she lounged on her stomach in bed, or flew like Superman. But spread-eagled.

Hip high, the position provided an excellent, up-close view of Kurt's impressive equipment. The flex and bob of his shaft in time to his pounding heartbeat fascinated her. She hardly noticed him placing a supporting headband rest around her forehead, taking the weight off her neck, because she couldn't focus on anything but his throbbing hard-on.

He stepped closer to attach the latest cord to the main support. While he concentrated on the task at hand, she snaked out her tongue then lapped at the bead of pre-come dripping down the head of his c.o.c.k.

Kurt's rock-hard thigh muscles quivered in front of her eyes. He slapped her a.s.s again, drawing a groan from the inner recesses of her chest. Her p.u.s.s.y flooded with arousal.

"Don't distract me, baby. I won't jeopardize your safety."

Though his serious tone attempted to squelch her rebellion, she couldn't help but test him. As soon as he rechecked his work, she strained her neck as far as she could to mouth his sac.

"Becca!" The chastis.e.m.e.nt came out as a rough moan. He couldn't restrain himself from thrusting his groin against her greedy lips for a few seconds before stealing her treat.

"Did you intentionally disobey me?" The rhetorical question highlighted the error of her self-indulgence.

But hadn't she expected him to punish her? Hoped for it? She made it easy for him.

"Yes."

He yanked the cables, spinning her ninety degrees until her hip came even with his front and her face pointed to his right. He gave her left cheek five rapid, stinging spanks. The crack of his hand against her a.s.s excited her as much as the tingling heat spreading across it. When he finished, his harsh breathing echoed in the room. She wished she could see his face instead of the corded muscles of his tense calves.

"Baby, if you want my hand on your a.s.s, all you have to do is ask. Do not disobey me again."

"Yes, Doctor." She grinned at the tremor in his voice, knowing he couldn't see. "Please, may I have more?"

His m.u.f.fled curse accompanied another s.h.i.+ft in her world as he spun her in the other direction then repeated the sharp slaps on her right cheek. She panted, recovering as he rubbed her a.s.s to ease the sting. The throbbing ache between her thighs prevented her from requesting additional punishment. He had to f.u.c.k her.

At her silence, he rearranged her to suit his purpose. His hands guided her legs into position, accompanied by the whir of motors. Her knees bent until her heels rested on the back of her thighs where Kurt banded them with yet another tie. He brought her arms together, folded so that her wrists rested at the base of her spine. The weight of her b.r.e.a.s.t.s swaying beneath her fanned the fire in her core.

Then, his touch vanished. He couldn't have gone far but, from this position, she couldn't find him. Her whimper became the only sound in the room. A moment of panic snuck in through the desire.

"Doctor?" Her question sounded like a distressed cry.

"Yes, baby?"

"Don't leave me. Please, touch me."

"I'm right here, sweetheart." His hand stroked her flank, rea.s.suring her. "Just stepped back to look at you for a minute. I can't believe you're real." He kept up a constant stream of insignificant ramblings as he retrieved the rolling tray with supplies he'd stashed out of Rebecca's line of sight.

Had he done that on purpose? What did he have on there?

She writhed in the bonds, attempting to steal a glimpse at the contents but couldn't manage it. Kurt dropped a restraining hand on the inside of her thigh mere inches below her p.u.s.s.y.

"You're soaked." Reverence saturated his tone. He must have bent closer because his breath teased her slick flesh. "You smell so hot, it makes me crazy. I have to taste you..."

The last of his words were m.u.f.fled as he sipped from her p.u.s.s.y.

"Oh, Kurt. Please." Pleasure arced across every nerve ending in her body.

"No, Becca. You can't come. Not until I give you permission. You're not hooked to any machines yet."

Pulling herself back from the razor edge of intense arousal, she panted, trying to squelch the electrifying sensations. Even as she registered the warmth and velvety glide of the doctor's tongue lapping the juices from her slit, she heard a latex glove snapping into place.

His gloved finger spread a cool glob of lubricant over her a.n.u.s. Shocked at the disparity in temperature, as well as the imminent possibility of penetration, she cried out.

"Tensing your body will make this hurt, baby. Relax." The lazy, seductive cadence inspired confidence.

Rebecca's muscles loosened up one by one.

Before she could frighten herself again, Kurt began to ma.s.sage her pucker with his gloved and lubricated finger as he bent forward to lick a path from the bottom of her swollen, dripping lips to her c.l.i.t. She bucked against the ecstasy. His finger nudged against her tight hole until the tip began to infiltrate a fraction of an inch at a time.

It felt forbidden, uncharted and so right to succ.u.mb to his penetration. In that moment, she realized she would surrender anything to Kurt. Not for the sake of the experiment, not for the resolution of her family crisis, not for the enrichment of her professional empathy but because she genuinely wanted to please him.

A strangled groan wrested from her constricted chest but she concentrated on the delight Kurt's tongue imparted as it rubbed a track down the edges of her slit before piercing inside then swirling around her c.l.i.t. On every pa.s.s, he withdrew his finger, spread additional lube across her back pa.s.sage, and then delved further inside as he distracted her from the burning discomfort by caressing her bud of nerves with his talented tongue.

When, at last, his knuckle pa.s.sed the final ring of muscle then plunged deep inside her, they both groaned.

Though she tried to relax, she was so turned on all her muscles clenched rhythmically. She gripped his finger.

"Please."

"No," he growled then bit the globe of her a.s.s. "d.a.m.n, baby. Your p.u.s.s.y is snug, but this is even tighter.

We need to do some more work here or I'm afraid I'll tear you when I f.u.c.k your virgin a.s.s."

Withdrawing the digit once more, he selected a tool from the tray. He showed it to her before going back to work. The flat leather base would fit the standard attachment he'd built into many of his inventions. For now, he clipped on a remote probe tool embedded in a thick d.i.l.d.o then pressed it inside the mouth of Rebecca's p.u.s.s.y with one hard stroke.

A wave of sparks radiated from the intrusion. She had to bite her lip to keep from coming right then. He'd instructed her to wait. But the bands wrapped around her body, the gentle swaying, and Kurt's touches pushed her closer and closer to o.r.g.a.s.m with every pa.s.sing second.

"Doctor, hurry. I can't wait much longer."

Kurt hooked the straps on the inserted device to clips in the bands encircling her waist. Now secured, the tool would measure her response without being ejected from her convulsing channel while he concentrated on preparing her a.s.s for his penetration.

Rebecca cried out when her inner muscles clenched around the implement but that alone couldn't satisfy her. The taboo pleasure zinging from his probing advances might push her over the edge when coupled with the instrument.

"I want you to wait, Becca. The probe is engaged now so I'll capture the data if you slip. But I want you to wait for my permission." She would do it. A large component of her satisfaction came from pleasing him.

"I'm going to stretch you now, baby. Open you up for my c.o.c.k." Kurt removed another apparatus from the tray. She watched him spread a generous coat of lube on the constricted ring. The device formed a ball with a dent running around the center like inverted rings around a planet. Beyond reasoning, she didn't venture to guess how he'd use it. "This is the smallest Stretcher I've made, but I think it's still going to be uncomfortable for you."

"Do it," she begged. "Please."

Instead, he knelt in front of her. Rebecca sensed the intensity of the doctor's attention through her closed eyelids. When she peeked from beneath heavy lids, Kurt captured her mouth in a blazing kiss. She matched his vigor and then some.

While engaged in the kiss, Kurt slid the Stretcher inside her a.s.s. The leading slope of the round gadget filled her, spreading her wider until the indentation ringing the sphere cradled her a.n.u.s. The bulges on either side trapped it in place.

He was right. The instrument felt huge, although she'd seen the modest size of the object when he'd cupped it in his palm. Her eyes rolled. She grunted at the burn in her a.s.s. She struggled against the bonds and the invasion.

G.o.d, if this is what the small intruder did to her, how would she ever take his c.o.c.k? She couldn't do it. The thought of disappointing him upset her, causing her to tense further.

Kurt grabbed a fistful of her hair, redirecting her focus back to him.

"Relax, baby." As waves of pain and pleasure collided in a cacophony of sensation, he nuzzled her neck, pus.h.i.+ng her over the edge from discomfort to arousal. The gentle vibrations of the objects embedded in her registered in her mind then began to enhance her stimulation. Stuffed, both her p.u.s.s.y and a.s.s clamped around his amazing inventions.

After a few moments, he smiled against her throat then raked her exposed pulse with the sharp edges of his teeth. He rubbed his c.o.c.k with the palm of one hand as though it hurt as much as she did.

"Good girl, Becca. How do you feel now?"

Words refused to coalesce in her usually articulate brain. All that would pa.s.s her lips was, "Mmm."

His contented laugh vibrated through her chest. Satisfaction layered on top of desire when she realized how much she pleased him.

"It's almost time, baby." Kurt clasped her shoulders then shoved. She spun around like the blades of a helicopter until she faced the opposite direction. Without hesitation, he clamped his mouth to her dripping folds, sucking her, licking her around the base of the probe. Her cries built in rapid succession as she neared the peak of her ardor.

She struggled to ignore the way her complete submission to his desires, as well as the devices embedded inside her, goaded her to come at once. A few more strokes of the doctor's tongue would make her fly over the edge.

As her weightless body strained toward release, Kurt tapped the device in her a.n.u.s to make an adjustment.

It flared, coaxing the ring of muscle further open.

Rebecca spiraled out of control. She twisted beneath his touch. Her heavy b.r.e.a.s.t.s rocked beneath her. Her overflowing p.u.s.s.y and a.s.s spasmed around the devious invasions. The ring in her a.n.u.s bulged further. The gradual expansion awarded her the chance to accommodate it and enjoy the sensation of being stretched.

She couldn't wait any longer.

"Kurt. Please. Now."

Instead of granting his permission for her release, he retreated, abandoning her on the cusp of a brilliant o.r.g.a.s.m.

"No!"

She watched him lunge to his feet in the mirror now in front of her. While she absorbed the shock of the loss, he pried the Stretcher from her then replaced it with the engorged, blunt head of his straining c.o.c.k. It seemed even bigger than before but she was so close to coming she reflexively squirmed closer. Or tried to.

"Take a deep breath," he commanded. Coating himself in her arousal and the abundant lubrication, Kurt notched his hard-on against her back pa.s.sage. He gripped the cables then used them to tug her onto his impaling flesh. The head of his d.i.c.k stretched her entrance. "When I tell you to, exhale and push out around me. We're going to do this. In one stroke. Just like you dreamed it. f.u.c.k, I don't think I'll last more than that in your tight, hot hole."
