"Yes, sir," I honestly replied.

"Do you understand the role of a slut?" He questioned.

"I'll follow your every command, sir," I murmured, looking at him.

"Without any hesitation?" he inquired as he removed his socks, confident that I would be just as eager as he was.

"Yes, sir, to the best of my ability," I reassured.

"Then prove it," he said as he leaned in, seizing my collar chain and relocating it to my back.

I looked at him innocently, silently wondering what more I could do to demonstrate my willingness. So, with great uncertainty, I submissively offered, "How, sir?"

He reclined comfortably, crossed his left foot over his right leg confidently, and firmly directed, "Suck my entire foot; let's see that big mouth get to work."

I obeyed without hesitation, just as promised a few seconds ago and prepared to do whatever he would instruct me, no matter how degrading it may be. However, I was unaware that this was merely the initial phase of humiliation. Leaning forward, I parted my lips and began to suck on his toes.

This was the most embarrassing situation of my life, but I didn't waste time thinking about it. Instead, I began sucking his foot while maintaining eye contact and remaining on my knees. I took nearly half of his foot into my mouth and slowly sucked it as if it were a large and thick cock while holding it firmly in both hands.

Despite the discomfort from my position, which made my neck ache, and my knees go numb, I kept sucking for at least two minutes. Then, taking it out of my mouth, I sensually sucked on each toe as if they were various-sized cocks.

I was determined to prove my point as his devoted sexual slave, and I prayed that the end result would be me tasting his dick for the first time ever and hopefully getting fucked soon too.

I kept sucking his toes until, out of nowhere, he abruptly asked, "What are you feeling?"

I removed his foot from my mouth and proudly answered, "I am entirely devoted to serving you as your submissive, and you are my dominant."

"What about your husband, Boudi?" He asked, referencing my significant other and pressing me to confront my last vestige of resistance, making it clear that our relationship would be strictly confined to Incest.

I suddenly paused, abruptly returning to the present moment, and I couldn't help but think that since this evening, I hadn't once thought about my husband until now. Not once did I attempt to resist him by mentioning my marriage, not even when he was intimately touching me in the car, not even when I entered his bedroom with expectations of having sex, not even when I stripped naked, and even half an hour ago, as I crawled naked and stayed on all fours until he completed his cigar.

I couldn't stop pondering how my actions would impact my marriage and the inevitable moment when my husband would discover that I had become his brother's personal plaything.

All this was going on in my mind, and out of nowhere, he placed his foot on my breasts, gripping my nipples firmly between his thumb and index toe finger, applying intense pressure.

The intense pain made me nearly rise to my knees, and I had to bite my lower lip to stifle any potential screams. Leaning to the left, I clutched his foot with both hands, silently attempting to stop his actions without uttering a single word. Tears welled up in my eyes as he roared, "Did I instruct you to stop?"

"Ah, uuuuuuuuuuh, I apologize, I just lost focus," I explained, trying not to scream even though the pain was still coursing through my entire body, but he had no intentions of stopping.

"Why is that?" he asked me. Finally, leaving my nipple, he stood up.

"I'm sorry, Master," I said, using the word 'Master' for the first time. I tried to be more submissive before admitting, "I just felt guilty."

"Why?" He inquired, repeating the same question.

"Because of your brother," being the wife, I answered.

"And you want me to stop then?" he teased as if offering me an opportunity to reconsider.

However, I had ventured this far, unwilling to abandon the path I had chosen in order to salvage my marriage. I confirmed, "I want to be your slut."

"What exactly would that involve?" he inquired, confident that I would be just as eager as he was.

I replied, "Unconditional obedience."

"What does that imply?" he inquired, attempting to pull out all my emotions.

"Being your twenty-four-seven sexual submissive," I answered without hesitation.

"Now, undo my trousers," he paused, then instructed with a playful twist, "Using only your mouth."

I was completely surprised by his playful demands, and I teasingly nibbled my lip, looking at him with a mock expression of annoyance and a playful smile.

I stood up on my knees and kneeled closer to his waist. Before unfastening his pants, I needed to deal with his belt, so I started to extract it from the loops using my teeth, a fairly straightforward task, though I was uncertain about how to unbuckle it.

Fortunately, he had a ratchet belt, which allowed me to release the buckle with my teeth. Once I had accomplished that, I pulled the belt out from the other side, and it slid out effortlessly.

Now, the challenge was to unbutton his pants. I decided to use my tongue for the job, taking the button into my mouth and attempting to push it free with my tongue. It turned out to be quite a challenging task, even more so than sucking the cock of my brother-in-law.

I persevered for over two minutes but couldn't succeed. However, I didn't give up, continuing to try. Finally, he intervened and offered to help, saying, "Let me assist you."

I removed the button from my mouth, and he unfastened it. Then, it was my turn to handle the zipper, which I found to be relatively simple. I grasped the zipper pull with my teeth and smoothly slid it down, causing his pants to loosen. By this time, he had already unbuttoned his shirt.

"Could you please turn around, sir?" I requested.

He agreed, and I gripped the edge of his trouser with my teeth and tugged it downward. He also lent his hands to bring them down, and fortunately, the pant descended.

"Now pull down my underpants," he said, turning around.

This time I used my hands, almost hanging in front with the help of my knees. I grabbed the waistband of his underwear and sought his approval with a glance. He blinked affirmatively. With his silent consent, I proceeded to lower his underwear.

I maintained unbroken eye contact, and his dick popped up right in front of my face. It was in a semi-hard state, not exceptionally large, but rather an average size of about six inches or a little bigger. He then stepped out of his pants and asked me, "Enough?"

I answered with a simple smile, "More than enough, sir."

"Good, now get to work." He demanded.

I eagerly reached for his dick and gently enclosed it with both hands as his arousal gradually intensified, just as I had anticipated. Then I slowly started to stroke it, which made him moan, "Ohhh."

I smiled playfully up at him as I leaned forward and took his cock in my mouth. He quivered with pleasure as I swirled my tongue around his mushroom top, moaning, "Oh, my."

The feeling of teasing was amazing and surreal, and I couldn't help but giggle as soon as I took out his cock from my mouth.

"You tease," he said with a sly grin, but then he forcefully grabbed my hair and pushed me back to the floor, treating me as if I were just an object.

I found myself on my back, safely cushioned by the thick carpet, which spared me from any potential injury during the fall. Yet, the impact did leave a lingering ache in my waist.

Nevertheless, I swiftly sat back up on my knees, and I apologized immediately and stammered, "I-I-I am sorry; I just wanted to be playful."

"Hands on your back, whore," he commanded, disregarding my apology and using the word 'whore' for the first time.

He retrieved the chain from the floor and settled on the left couch, now positioned to face the door. This time, he extended his right leg onto my chest and warned me, "However, there will be consequences for such disrespectful behavior."

"Yes, Master," I nodded. The punishments could be painful, yet they also aroused me.

Before I could finish my word, he pinched my nipple in the same way, this time with even more force. The pain was excruciating, causing me to lean forward and struggle to breathe, but I obediently placed both of my hands behind my back, as instructed, and remained the epitome of submission, enduring the pain.

Fortunately, this time he showed some sort of mercy and didn't keep pressing for more than 10 seconds. But that was sufficient to bring tears to my eyes. Soon thereafter, my heart rate accelerated, and I experienced a peculiar physical exhilaration as he began to relax his grip on his toes.

"You can have your reward now." He stated, spreading his legs wide.

I already messed up with three blunders. The first was in the car when he was about to finger fuck me; the second was when my husband's name crossed my mind while I was sucking his foot; and the last was when I attempted to be playful and tease him instead of sucking his dick. I decided not to make the same mistake again.

Eager to put that dick in my mouth, I anxiously crawled forward, but then suddenly he stopped me once more by gently pressing his foot against my chest and saying, "Wait."

I immediately paused.

"Pull your tongue out," he ordered.

Without any hesitation, I took my tongue out of my mouth as far as I could, allowing myself to be treated like a well-trained dog.

"Do you want to suck your brother-in-law?" Samar asked, bringing up our sacred relationship just before committing incest. But I had already moved beyond such considerations.

"Desperately," I answered, my mouth watering looking at that dick.

"And you're willing to do anything for it, don't you, Boudi?" He asked again, using the word 'Boudi'.

"Anything," I answered honestly, as I felt his leg gliding slowly down from my navel.

"Even in front of your husband?" His leg is now touching my clit.

"Even when standing on a stage with thousands of people watching me," I declared, losing the last shred of dignity I had.

"Umm, why are you wet?" He asked, pushing his thumb toe inside my hot box.

"With the anticipation of sucking your cock, stroking it, taking it in my eager cunt, and then swallowing it," I answered, trying to be as blunt as possible.

"I see; beg for it then," he ordered.

The sensation was so wild, and the desperation of sucking his cock was at its peak, that I attempted to be open and honest and remove the boundaries, if there were any, at this point in time. So, I babbled, "Please allow your Boudi to suck your precious cock; make me your dirty little plaything, your fucking incest slut."

"Um, you may suck it now," he declared.

I wanted to become his preferred slut, surpassing his other partners. So, I quickly approached him and gently grasped his cock. Leaning in, I sensually traced my tongue along its length, from bottom to top, reminiscent of the way I had enjoyed an ice cream cone earlier that evening. I continued to lick every inch until it was completely covered in saliva.

While I was busy serving his cock and enjoying the moment, he was pushing his thumb toe inside my pussy and doing in and out from time to time, making me shiver and moan.

As his dick was all wet, I gently stroked it a few times to increase its firmness before taking it into my mouth. However, unexpectedly, he pressed his thumb-toe firmly on my pussy, causing me some discomfort. I quickly reacted by moving myself up to his thighs and keeping stroking for a few more minutes.

I couldn't hold back any longer, and with eager anticipation, I slowly and sensually took it into my mouth, gradually accommodating more and more of his dick, determined to take it all the way in.

Nevertheless, I couldn't keep it for long, as it was the thickest among those I had taken. I briefly withdrew, but inhaling deeply, I quickly resumed, closing my lips to cover my teeth. With a gentle and rhythmic motion, I began to suck up and down.

His dick started to grow and became stiffer in a matter of moments, pressing against the back of my throat, and it kept pushing deep. The soft moans escaping his lips enhanced my enthusiasm, and with every downward bob, I eagerly took more of his cock.

After a couple of minutes of thorough sucking, it slid over six inches. Keen to eventually take every single portion in my mouth, I did one decisive push, and his dick slid entirely in, making contact between his groin area and my upper lips.

Once it disappeared entirely within my mouth, he seized the back of my head and continued applying pressure. My blood vessels were on the verge of closure, causing me to choke. In desperation, I tapped his thighs, pleading for mercy and begging him to release his grip on my head, but he showed no intention of stopping.

Nearly a minute later, he abruptly pulled my hair, prompting me to remove his member from my mouth. Rising to my knees, I looked at him with a coy smile as my face glistened with saliva, some of which trickled down my chin.

I inhaled deeply, then gently rested both my hands on each of his thighs and softly expressed, "I can't believe that I just had my brother-in-law's cock in my mouth."

He too smiled back while looking at me in awe and replied, "And I can't believe I'm watching my sister-in-law sucking my cock."

"Your obedient twenty-four-seven slutty sister-in-law." While giving him my full description, I chuckled.

Before he could say anything, I leaned forward, and taking his dick in my hand, I started stroking it nice and slow.

He too smiled back, relishing my dirtiness and bubbliness as he gently slid his foot between my legs. His touch on my clit made me moan louder this time since my pussy was burning like fire, both wet and horny from the constant tease and small touches from time to time.

Recognizing this, he increased the speed and inquired, "Boudi, do you masturbate?"

Taken aback, I gasped. Clearly not wanting to answer that, I focused on stroking his cock and thoroughly sunk in the delight of the pleasure he was giving me with his leg. Nonetheless, he continued his endeavors to spare me from any awkwardness at that instant, and thus, he persisted, saying, "Oh, come on, Boudi, tell me."

Looking at him with my dilating pupils, I replied, "Uh, yes."

"And you were masturbating before I had reached your home, didn't you?" He was quite certain about that, as he kept rubbing his feet on my clit.

"Ahhh, yes," I replied with a simultaneous moan.

He abruptly stopped and instantly demanded, "I want you to fuck yourself," then added yet another twist, probably just wanting to see how slutty I could be. "You can't use your fingers or my leg."

I loved just how naughty the idea was, but I decided to outwit him as I slowly stood up. I had knelt for over two hours, and when I finally rose, my legs had gone numb, but I didn't care. I simply placed both of my hands on his shoulders and moved close to him. I straddled him by lowering myself onto his cock, leaning forward so my tits were in his face, and he too grabbed my ass.

"Hey!" Samar protested. "That is cheating."

"It's neither your toes nor my fingers," I remarked as I sat down, and almost his entire cock incredibly smoothly and effortlessly slid into my wet pussy.

"Fair enough," he chuckled. As I started riding his cock slowly, he demanded another wish, "But you can't cum without my permission."

"Ahh," I moaned as I felt his dick hitting my lower abdomen. But I couldn't feel the pain as my orgasm started to build within me. From the moment he started rubbing my clit with his feet and outburst at any moment, I announced, "I'm not going to last much longer."

"Umm, you seem to be quite experienced in this," he remarked, his groan mingling with the sound of my hips meeting his thighs in the room. He then asked, "When was the first time you had sex?"

"What!" I gasped in surprise at his weird question.

"Answer me," he insisted, holding onto my waist and assisting me in bouncing with the same rhythm on top of his dick.

"I was 23." Inhaling deeply, I answered while instinctively grasping his neck, seeking support to continue as my legs began to weaken.

"With whom?" he asked, and his breath started to get heavy.

"Please..." I begged, uncertain about how to respond. In this newly formed, honest relationship, I couldn't bring myself to tell a lie, nor could I reveal the dirtiest past. So, I initially hesitated for several minutes, resisting the urge to reveal my secrets, but in the end, I decided to trust the man I was serving as his plaything.

More than that, desperately wanting to cum, I finally confessed the darkest secret I had ever held. I whispered, "With my mother."

"You filthy lesbian mother fucker," he described.

"Please allow me to cum." I pleaded, disregarding his words, sensing that I was close to cum and could explode at any moment.

"Fine, you may cum on my count of twenty," he said as he paused, shifting his hand from my buttock to the crevice between them while I kept straddling his cock. Then he added, "But you must control yourself till then."

"Umm, you dirty boy..." knowing that I wouldn't last till ten, but rather than arguing with him, I begged, "Please start counting."

"Twenty." He began counting in reverse, and I noticed his hand steadily approaching my butthole, making me more uncomfortable.

"Nineteen." He counted after a second as I felt some part of his cock rubbing my clit.

Then he paused for two seconds, and I swiftly implored, "Don't stop, ahh, fuck, please don't stop, sir."

He immediately said, "Eighteen."

Certainly, I realized my pussy was releasing precum, and those extra fluids were making his dick slip deeper, and my bouncing speed automatically increased.

He took another long couple of seconds gap, and I couldn't help but express my frustration with a hint of annoyance and moans, "Uh, um, you're not counting, sir."

"Do not cum until I finish," he urged as he sensually traced his finger around my butthole entrance, poised to enter.

"Uh," I felt awkward as his finger was about to enter my asshole, then I complained, "But at this pace, I won't be able to hold on until fifteen."

Instead of counting, he asked, "Tell me five things you did with your mother during your incest playtime, and you may cum."

Out of nowhere, a vivid image of my mother popped into my mind. She was lifting a kitchen wiper, clad in an apron with its ties gracefully trailing behind her ass, while her ample bosoms were popping out, making them prominently on display. I couldn't help but reveal in the heat of the moment, "She did all household work throughout the day, dressed in nothing but an apron."
