Chapter 8
Of course T'Challa didn't stop then. Omegas were able to have multiple orgasms, and even though Erik was already whimpering from overstimulation, T'Challa continued to finger him open before proceeding to fuck Erik.
His desire temporarily sated, Erik lay pliant and breathless under T'Challa, squirming a little as T'Challa's cock slid into him, past the slick, loosened ring of muscles, until he was fully sheathed within Erik's ass.
Bast. T'Challa's cock was deliciously long and thick, so much better than his fingers. He fucked into Erik at just the right angle to hit Erik's prostate and have him seeing stars. T'Challa tightened his fingers into the side of Erik's hips and began to pound into his sore ass, drawing a little hiss from Erik on each inward thrust.
T'Challa wasn't being gentle this time, fucking Erik hard enough that each thrust of his groin against Erik's tender ass felt like he was being spanked all over again. But the rough treatment was exactly what the omega in him wanted, and Erik was writhing in pleasure as the alpha ground his cock deep into his body, setting off sparks of pain and pleasure inside and out.
Erik was already oversensitive from the spanking and his first orgasm, and he came again in an embarrassingly short amount of time, howling his muffled pleasure into the bedsheets as T'Challa cornrinued to fuck him ruthlessly through it. T'Challa finally knotted in him a moment later. His fingers dug into the side of Erik's hips again, keeping Erik firmly in place on his cock as his knot began to expand with bruising force, knocking the air out of Erik's lungs. Automatically, Erik clenched down as his insides rippled around T'Challa's knot, milking the come dry from his cock with each hard squeeze.
It took Erik a few moments to catch his breath again. Pleasantly sated and enjoying the feeling of being stuffed full of his alpha's cock, Erik offered no resistance as T'Challa shifted them so that he was sitting on the bed and Erik sitting on his lap. T'Challa's knot shifted within him with their movements, too tightly locked to slip out of his hole. It was a strange but not unpleasant sensation, but Erik inhaled sharply as his tender ass made contact with the tops of T'Challa's thighs.
He leaned back against T'Challa's chest, biting his lip as the knot adjusted within him with every movement. It was difficult to get comfortable when he was so aware of just how sore he was, inside and out.
T'Challa's lips brushed against the side of his cheek. Erik grumbled a little under his breath, but otherwise didn't protest.
"Are you going to behave now?" T'Challa murmured against his ear.
The message was clear: Behave, and be rewarded. Misbehave, and be punished.
Erik's ass throbbed with the reminder of the paddling. He shifted irritably in T'Challa's lap, but only succeeded in putting extra weight on a particularly tender spot. Erik sucked in a sharp breath at the sting, and the vibration from T'Challa's answering chuckle reverberated against his back.
--
Several weeks later
It wasn't that Erik had had a change of heart, exactly. It was simply…easier, not to oppose T'Challa at every turn. To go along with the flow and accept whatever his very indulgent, very attentive alpha offered. After all, it was only sex, Erik told himself. He had had plenty of fun meaningless sex before, and this was no different. That was all it was. Just very meaningless, very enjoyable sex with a handsome alpha. Any omega would be a fool to turn that down. And it wasn’t like he was submitting to T’Challa. He was just making use of the alpha, waiting for the right opportunity to stab T'Challa in the back when the time was right.
In the meantime, there was no reason why Erik couldn’t enjoy himself.
Darkness, velvety soft and black, settled over Erik’s eyes. A warm embrace of nothingness.
Erik blinked, but the black veil over his eyes blocked out his vision. He was almost, but not entirely blinded. Around the edges of the blindfold, he could see a thin strip of light, and part of the bridge of his own nose, but nothing significant at all of his surroundings.
He twisted, testing at his restraints - the silk ties around his wrists and ankles, binding him spread-eagled and face down to their bed, with his hips propped up by two pillows. The ties were made of silk thread with a vibranium weave, strong enough that even T’Challa would have difficulty breaking out of them, but soft enough that the material wouldn't cut painfully into his skin even if he struggled.
Erik shivered, then lay still. With the loss of the most important of his senses, he felt incredibly vulnerable. All the sensations in his body felt magnified a hundredfold - the whisper of silk against his skin; the scent of alpha arousal in the air, triggering an answering increase of slick in his hole; the heavy, even sound of T’Challa’s footsteps, moving around the room.
What was T’Challa doing?
Erik's breathing sped up as he sensed the alpha drawing close. He knew, intellectually, that he didn't have anything to fear, but being defensive was in Erik's nature. Instincts beaten into him throughout a lifetime of fending for himself were hard to shake. Erik reminded himself that it wasn’t like he had any choice about submitting to T’Challa, and somehow, that thought made him calm down, as fucked up as it was. The omega side of him loved nothing more than submitting to his alpha during sex.
The blindfold had been T'Challa's idea, and the restraints as well. Those were just the latest of the many, many sex toys that they were in the process of testing out. Erik had made only token protests about most of the toys - toys such as the high-tech vibrators (calibrated to automatically take into account and respond to Erik's bodily reactions), the butt plugs (molded in the exact shape of T’Challa’s knot), and the jewelled anal beads (one glance had told Erik that they probably cost more than an average person could earn in a year). All of which Erik had ended up vocally enjoying. Despite this, he had still been wary about letting T'Challa use the blindfold and the restraints. Those, he had protested vigorously. They represented a loss of control and autonomy that Erik was frankly terrified of, even if he was just to his guardian alpha.
But T'Challa had managed to talk him into it in the end.
Erik shuddered again. “T’Challa,” he called out. With his face pressed into the mattress, the word was muffled, but he was sure that T'Challa's herb-enhanced senses would have no difficulty picking it up. "What are you - ohhh."
Something came down on his ass, covering most of his right ass cheek. T’Challa’s palm. Erik jerked, then tensed as T'Challa began to stroke him, skimming his hand lightly over Erik's skin. With the loss of his sight, the sensation of that light touch felt shockingly intense, and goosebumps rose on Erik’s skin as his entire world narrowed down to the sensation of T'Challa's hand cupping and stroking at his ass.
Erik exhaled slowly, relaxing in his bonds as T'Challa continued to lazily pet and stroke him. The tips of T'Challa's perfectly manicured fingernails scraped against Erik's skin, sending a shudder up his spine. It felt good. Unconsciously, the beginnings of a purr began to rumble within Erik's chest. He stretched lazily across the bed, as much as the bonds would allow.
But nice wasn't what Erik wanted.
Impatiently, Erik shifted his legs further apart, arching his back to show off his ass in obscene invitation, thrusting his ass back into T'Challa's hand. Although he couldn't see, he knew without a doubt that T'Challa was smiling.
T'Challa's hand came down on his ass again, in a light slap this time. Erik gasped and tensed at the unexpected shock of stinging pain. It quickly faded into a tingling warmth that spread across the surface of his skin.
Another smack, light and playful, landed on his left ass cheek. Erik moaned, squirming in his bonds. The scent of omega arousal hung heavy in the air.
“Ready?”
Erik made a soft, wordless noise of assent. He was so ready.
But instead of the cock which Erik had been expecting, something large and unyielding pushed into his ass. Surprised, Erik tensed around it, even as his body reacted to the intrusion by instinctively producing more slick to ease the entry of the object.
It was much the same size and girth as T’Challa’s cock, except it was slightly colder than body temperature, and very obviously not organic. One of T’Challa’s new sex toys. Was it made of silicone? Or some sort of vibranium alloy? Erik couldn’t tell. The object was ridged along its length as well, and Erik whimpered at the foreign sensation of the bumps and ribs sliding against his inner walls. He flexed experimentally around it, clenching his ass as T’Challa thrust it ever deeper into him. Was this the dildo from yesterday? Somehow it didn’t feel the same.
T’Challa continued to push the toy into his ass, working it in with shallow thrusts, inch by inexorable inch. Erik's breath hitched as his hole stretched around the toy. He had never taken anything quite so long and irregularly shaped in his ass before. It felt strange, but not in an unpleasant way - just a completely foreign sensation that had the hairs on the back of his arms standing on end.
When the flared, thickened base of the toy finally hit his ass cheeks, Erik was panting hard from the effort of trying to relax around it. The dildo was at least several inches longer than T'Challa's cock, and T'Challa himself was already packing. Erik clenched around the intrusion again, and the ridges on the toy pressed oddly up against his inner walls in a way which made him feel like he was being massaged from the inside. He could feel every inch of it rubbing against his insides. Erik squirmed, frowning into the darkness.
T'Challa began to fuck the toy leisurely in and out of him, thrusting it in him at just the right angle to make it rub against his prostate. More slick gushed within him, around the toy, and Erik shifted his legs further apart, gasping as it forced his inner walls wider apart. T'Challa continued to work him loose with steady thrusts, occasionally twisting the toy in a way that made Erik yelp in a completely undignified manner.
But he was getting used to it now as his hole adjusted to accommodate the stretch. Erik wriggled against the restraints again, letting out a whine. “I thought you were going to fuck me,” he complained. "Not just a fucking toy."
T'Challa laughed. Then suddenly, the dildo in his ass began to vibrate.
Erik cried out in shock, tensing against the restraints. Every nerve in his body seemed to light up at once as if he had been shocked with an electric charge. Wave after wave of vibrations pulsed through him. They were irregular but surprisingly strong, shocking him in a completely unpredictable rhythm which made everything feel so much more intense.
Erik yelled, muffled, into the bedsheets. "What the fuck? - Oh, fuck!"
Without warning, T'Challa increased the vibration of the dildo, ratcheting it up yet another notch. Erik yowled, his fingers clenching his toes curling as he drummed his feet against the top of the mattress. The restraints didn't give, and squirming just made the broad, ridged end of the dildo rub up against his prostate, making him see stars. He whined, tears beginning to burn in the corners of his eyes.
"Keep that in you," T'Challa directed. "Or you'll regret it."
To emphasise his point, T’Challa slapped Erik on the ass, hard and low across his ass cheeks. His ass jiggled under the force of the spank and Erik jerked, instinctively clenching around the dildo. Tightening around the vibrating toy made pleasure flare within him again, hot and almost unbearably bright. The tingling ache left behind in the wake of that slap throbbed in time with the vibrations of the dildo in his ass.
T’Challa released his grip on the dildo. Without the force of his hand keeping it in, Erik’s instinctive reaction was to try and push out the intruding, vibrating object, but the fear of his alpha’s displeasure made him fight the urge down. Erik whimpered. Obediently, he tightened around the toy again, and the ensuing wave of vibrations stimulated a fresh wave of squirming that drove him ever closer to the edge. His cock was now rock hard and leaking against the bedsheets.
Oh, Bast. T’Challa was setting him up to fail. There was no way he could keep the dildo in for more than a few minutes without breaking down and begging T’Challa to take it out.
“How - for how long?” Erik managed to gasp out.
He could hear the smirk in T’Challa’s words. “Until I say it’s enough.”
Erik sobbed.
There was a spreading patch of dampness on the bed beneath his cock. His thighs were quivering and his muscles felt like jelly. His ass was a hot, aching burn of pain, sore inside and out, a sting which intensified each time he forced himself to clench down on the vibrating dildo. But the pain was a distant distraction. All of his attention was focused on keeping that damned toy within himself.
He wasn’t succeeding.
He had let the vibrator slide out of his ass twice already. Once when he had orgasmed so hard that he lost all conscious control over his muscles, and the second time when he had deliberately let it slip out when the stimulation from the vibrations had become too much to bear. Both times, T’Challa had made him regret it. Despite Erik's squirming, T’Challa had forced the dildo back into him,then spanked him so hard that Erik had been left breathless and whimpering. Each slap reverberated through his ass, intensifying the sensation caused by the vibrations until Erik was yowling and begging wordlessly for mercy.
Erik gritted his teeth as his body was wracked by a new wave of arrhythmic vibrations. He whined, a high-pitched needy sound, and clenched his hands into fists so tightly that his fingernails cut into the soft skin of his palms. He clenched down hard around it, whimpering as the ribs along the shaft nudged against the oversensitive walls of his channel.
The scent of alpha pheromones filled Erik’s nostrils, a familiar spicy musk that electrified his nerves.
T’Challa.
At some point in time, he must have entered the bedroom again while Erik had been too preoccupied with the vibrator to notice. Erik's body instinctively reacted to the presence of an aroused alpha nearby. His heart rate spiked and more slick gushed from between his legs, around the toy in his ass. A fresh wave of need wracked Erik’s body. He squirmed, lifting his hips and arching his back as he heard the sound of the alpha's footsteps approaching.
T'Challa was so close now. So very close.
A frisson of anticipation ran up Erik's spine. Erik panted against the sheets, shifting his hips so that he could get more friction on his cock to distract himself from the vibrations in his ass. He desperately wanted to rub himself off right now, but his hands were still bound. Despite the silk material, the restraints were beginning to chafe against his wrists, and holding the position was starting to feel uncomfortable. His biceps were already aching, and his thighs were shaking under the strain from keeping his internal muscles clenched while being restrained in a spread-eagle position.
A hand came down on the back of his head, caressing him lightly. The touch of T'Challa's hand against his heated skin was like water to a starving man in a desert, cool and soothing. Even though Erik knew that T'Challa was the source of his torment, he couldn't help but lean in towards the comforting touch, lifting his head as much as the restraints would allow to try and get closer to T'Challa.
T'Challa's hand moved lower, stroking small circles on his back this time. At the same time, a fresh wave of vibrations racked Erik's oversensitive body.
Erik cried out, tensing and jerking in the restraints. The smell of alpha arousal was overpowering now, driving him wild with lust. It was unbearable.
He couldn't take another orgasm. His dick was going to break. Erik groaned in frustration. “Enough,” he said, his voice hoarse and broken. He let out a frustrated hiss of air through clenched teeth. “Fuck. Just take it out, damn it."
Without warning, T'Challa spanked him hard on the ass. Erik yelled, clenching down hard around the toy, his ass quivering under the force of the slap and the relentless, irregular vibrations. A pitiful whine escaped his lips.
"Just one more thing," T'Challa purred. "You can take it, I know you can."
Blessedly, the vibrations finally stopped - T'Challa had turned off the vibrator at last. But Erik only had a moment’s reprieve before he suddenly sensed the base of it expanding within him, forcing his inner walls apart just like an alpha’s knot.
Erik's eyes widened behind the blindfold as the pressure within him built. He could feel every ridge and bump on the dildo brushing up against his inner walls.
Erik wriggled in discomfort. “It’s too big!” he protested.
“Breathe,” T’Challa said. “It’s not thatmuch bigger than a regular knot.”
That wasn’t exactly comforting. But T’Challa stroked Erik’s ass cheeks, fondling and soothing away the sting, and Erik tried desperately to do as he was told. His thighs trembled with the effort of trying to relax around the expanding dildo. The base of the toy was inflating much more slowly than a real alpha’s knot, and the consequence of it was that Erik could feel it expand within him but by bit, centimeter by centimeter, every bump along the shaft lighting up the nerves in his sore ass.
"Oh - oh fuck -" Erik moaned.
He quivered with the effort of forcing himself to breathe and take it in, trembling as his hole stretched around the slowly expanding base of the toy. It burned, right on the knife's edge of pain and pleasure, and he was a shaking, whimpering mess by the time the inflatable knot on the dildo finally reached its maximum expansion. It felt as if someone had forced a baseball up his ass. It was so big and solid. Erik squirmed in discomfort, his hole spasming around the fake knot as he tried to catch his breath.
"Good," T'Challa praised, his voice soft and approving. "I knew you could do it, love."
Erik turned his head blindly towards the source of the voice, seeking out comfort. His ass throbbed around the huge knot. He was at the limit of his endurance. All he wanted to do was collapse into a puddle of exhaustion and curl up next to T'Challa.
But -
"Five more minutes," T'Challa said decisively.
Erik's heart sank. "Five more minutes?"
T'Challa tapped his finger on the base of the toy, sending a jolt through Erik's ass as it shifted deeper into him. Erik bit down hard on his bottom lip, just barely managing to hold back a yelp. He whimpered, tears of discomfort burning in his eyes as his ass quivered around the enormous knot.
"T'Challa!" Erik protested.
T'Challa swatted him again, one slap against each ass cheek. This time, Erik did yelp out loud. Pain throbbed through his ass, flush at the surface of his sore, tender skin, reverberating through his over-stretched insides stuffed full of the huge toy.
"Five more minutes," T'Challa repeated.
Erik buried his head in his forearms and gritted his teeth, squeezing his eyes shut behind the blindfold.
