The BDSM Contract I Signed on My Knees

The first time I entered Darío’s office, I already knew I wasn’t going to leave unchanged. Not because of the contract he had sent me beforehand, nor because of the rules written with an almost surgical coldness, but because of the way he made me wait standing beside the door while he finished arranging some papers without even looking at me.

The room smelled of leather, ink, and waxed wood. In the center stood a broad table, too clean, with a single open black folder and a silver pen resting on top. I was wearing a dark dress, sheer stockings, and a knot in my stomach that was neither pure fear nor pure desire, but something deeper, more dangerous.

“Close the door and kneel,” he said at last.

He didn’t raise his voice. He didn’t have to. The dry way he said it emptied my chest and brought me to the floor before I had time to think about it. I felt the cold tile beneath my knees and the immediate pressure of that position. He remained standing, immaculate, his pale shirt rolled up to his forearms and his gaze fixed on me as if he were already inspecting a newly acquired property.

“Read the last page again,” he ordered.

I took the folder in both hands. My signature was at the bottom, firm but slightly shaky. Above it, on several clauses, he had made marks in red. Schedules. Nutrition. Training. Corrections. Restrictions. Use of the body. Denial of orgasm. Availability. Verbal obedience. Silence outside designated hours. Everything was written with an obscene precision that squeezed me from within more tightly than if he had put a hand around my throat.

“Say it out loud,” he instructed.

I swallowed and obeyed.

“I accept surrendering control of my routines, my physical and sexual conduct, and the corrections necessary for my discipline.”

He took a step toward me.

“To whom?”

“To you.”

His expression didn’t change.

“No.”

I understood at once. I lowered my gaze, embarrassed by the mistake, and corrected myself:

“To you, Darío.”

“Better.”

I signed the final line while he watched me. The sound of the pen moving across the paper seemed more intimate to me than any kiss. When I finished, he took the folder, calmly reviewed every page, and put a copy into a transparent sleeve. Then he crouched in front of me for the first time. He didn’t touch me. He only held my chin between two fingers and made me look at him.

“You can still change your mind before it begins.”

I felt the pulse between my legs, dull and insistent.

“I don’t want to change my mind.”

“Then from now on, you obey without arguing, answer clearly, and take no pleasure without permission. If you don’t understand an order, ask. If you understand it, carry it out. Is that clear?”

“Yes, Darío.”

He released my chin and stood again. Then he hung the sleeve containing the contract around my neck with a black ribbon. The plastic rested against my sternum and, when I breathed, brushed the fabric of my bra. The gesture was simple, but it aroused me immediately. Wearing the contract over my breasts, almost like a badge, made everything more real than any fantasy I had masturbated to alone in my bed.

“Stand up. Undress until you’re left in your underwear.”

I rose slowly. My knees cracked a little, which made me feel clumsy and watched. I took off my dress and let it fall. I was left in a white bra and matching panties, far too simple for a scene like this. He made me turn without touching me, guiding me with his voice.

“Arms behind your back. Back straight. Legs apart.”

I obeyed. The air in the office clung to my thighs. Darío took a notebook and began to write. I didn’t know what he was recording, but the mere fact of being reduced to a list of observations made my pussy wet so quickly that I had to press my lips together to keep from moaning.

“Nipples hard with anticipation,” he murmured as he wrote. “Good response to visual control.”

The humiliation struck me with a sweet violence. He spoke about my body as if it were a file, and all I could think about was opening my legs wider.

“Turn around again.”

I did.

I heard the rustle of paper, the tip of the pen, his footsteps behind me. When he spoke, his voice sounded very close to the nape of my neck.

“I’m going to establish your first routines. You’ll wake when I tell you to, train as I tell you to, and give me daily reports if I ask for them. Your body is no use to me exhausted or capricious; it serves me disciplined. Understood?”

“Yes, Darío.”

“If I give you a position, you hold it. If I tell you to count, you count. If I order you to come, you come. If I order you to stay on the edge, you stay there even if your legs are trembling. Understood?”

My pulse pounded in my throat.

“Yes, Darío.”

“Good. On all fours beside the sofa.”

I went there with the contract bouncing against my chest. I positioned myself on the floor, resting on my hands and knees, and immediately felt the brutal vulnerability of that position. Darío opened a drawer and took out a broad black leather collar with a metal ring at the front. When he fastened it around my neck, he didn’t make it too tight, but the fit was enough to make me conscious of every breath.

Then he took my wrists and brought them behind my back. He tied them with a short strap, just enough to keep me from sitting up properly. My chest sank lower, my ass rose higher. A position designed to display me.

“Now the real evaluation begins,” he said.

He stood watching me for so long that it seemed endless. I could hear the distant hum of the air conditioner, my own inhalations, and the little tapping sound of the plastic contract brushing my skin. My ears burned. My sex burned. He still didn’t touch me.

“You’re getting wet all by yourself,” he finally remarked.

No part of me answered except for a tremor in my thighs.

“Answer me.”

“Yes, Darío.”

“That’s good. An honest body saves time.”

I felt his hand on the back of my neck, followed by a small cold device pressing against my nose and restricting the flow of air. It wasn’t entirely painful, but it was uncomfortable, demanding. Every breath became tight and controlled. He left me like that for several minutes, watching me. At first I thought only about not failing; then the effort began to descend through my belly and concentrate between my legs. The partial lack of air left me sensitive, alert, absurdly aroused.

“Don’t move,” he warned.

I remained still, gasping through my nearly closed nose and half-open mouth. A thread of saliva formed and fell to the floor. How humiliating. How badly I wanted to continue.

When he removed the device, I drew a deep breath as if I had just come out of the water. He gave me only a few seconds to recover before running his palm over my buttocks. It was a light, exploratory touch, and even so it made me arch my back.

“First offense,” he said coldly. “I didn’t ask you to react.”

“I’m sorry, Darío.”

“Sorry doesn’t correct anything. Punishment does.”

I heard him open another box. Then I felt him slide my panties down my thighs until they were caught around one knee. The air hit my wet pussy and my ass full on. I wanted to close myself out of sheer embarrassment, but I didn’t dare. He stroked one buttock and then the other with the tip of a braided leather instrument.

“Five to open you up. Count.”

The first smack tore a dry gasp from me. It burned like a precise, living line of fire, far more intensely than I had imagined. It took me a second to find my voice.

“One.”

The second landed across the other buttock. Higher. Hotter. The pain arrived with a jolt that traveled through my pussy and made it throb.

“Two.”

The third made me clench my teeth. The fourth left me trembling. By the fifth I was already breathing unevenly, tears in my eyes and my crotch scandalously soaked.

“Five,” I whispered.

Darío laid his open hand over the heat of my marked buttocks and stroked me slowly, as if checking the skin’s response.

“Very good. Your body learns quickly.”

He slipped two fingers between my legs without warning. He found my wet pussy and gave a brief, low laugh.

“Look at you. I hit you and you gush.”

I felt him part my lips with his fingers and brush me exactly where I was most sensitive. He didn’t penetrate me right away. He merely played around my clitoris, spreading my wetness and provoking little bursts of pleasure that forced me to bite my lip.

“Don’t come.”

He inserted one finger. Then two. They slid in easily, gliding through my own arousal. At first he moved them slowly, barely bending them inside me, exploring. Every caress left my belly tighter.

“Tell me what you feel.”

“That...” I had to draw breath. “That I want more.”

He kept moving his fingers, now deeper, rubbing me inside with cruel patience.

“I didn’t ask what you want. I asked what you feel.”

A moan escaped me before I could answer.

“I feel like I’m going to come if you keep doing that.”

He withdrew his fingers at that exact moment. The absence truly hurt. I let out a humiliating, needy whimper, and that only made him smile.

“That’s the idea.”

He wiped his wet fingers along my cheek and then over my lips.

“Taste your obedience.”

I opened my mouth. He pushed two fingers in until I could taste my own lubrication, salty and hot, with a faint metallic flavor from the tension. I sucked them without losing my position.

“Swallow.”

I obeyed.

“Again.”

He pushed them in once more and pressed my tongue down. I closed my lips and sucked slowly, feeling him watch me. When he withdrew them, saliva gleamed on my chin.

“From now on, your pleasure also passes through my mouth and my cock,” he said. “You won’t decide when, how much, or how.”

He unbuckled his belt. The sound of the metal made my entire body tense. He lowered the zipper and took out his cock, thick, still half-hard, heavy in his hand. He stood in front of my face and hooked two fingers into my collar to pull me closer.

“Mouth open. Tongue out. Don’t suck until I tell you to.”

I did it immediately. Shame had me burning, but it also emptied my head of everything except obedience. The tip of his cock brushed my tongue. It tasted of clean skin, of man, of a little contained sweat. He slid it across my mouth without entering fully, smearing me with saliva, tracing the outline of my lips as if he were using me to wet himself.

“That’s it,” he murmured. “Still.”

He pushed very slowly until only the tip entered my mouth. He withdrew. He came back in a little farther. I wanted to close my mouth, suck, do something, anything, but I remained motionless. The effort of not taking the initiative aroused me almost as much as having him over me.

“Now. Suck.”

I closed my lips around the head of his cock and knew at once that it was harder. I ran my tongue over it, slowly, obediently, and he let out a satisfied huff. He held my hair with one hand, without unnecessary violence, just to guide me. He went deeper. As far as my mouth received him without difficulty. He pulled out. Then pushed back in.

“Deeper.”

I obeyed. My throat tightened when he filled it a little more abruptly. I coughed faintly, and he pulled my hair back to correct me.

“Breathe through your nose. Relax.”

I tried. I lowered my shoulders. I opened my throat wider. His next thrust went in better. I sucked him hungrily, no longer able to conceal how aroused I was by feeling him grow fully hard in my mouth. Saliva ran down my chin and fell onto the plastic contract, wetting it. Seeing that out of the corner of my eye unleashed another spasm of desire.

He began setting the pace with his hips. It wasn’t brutal yet, but it was firm. He fucked my mouth slowly, pulling almost his entire cock out and putting it back in with a wet sound that filled the office. I drew air however I could between strokes, my throat opening wider, more submissive, more willing.

“That’s it. You serve me well like this.”

The words, rather than humiliating me, sank me into a strange calm. I was on my knees, tied up, my ass burning and my mouth full of his cock, and yet I felt exactly where I wanted to be.

Darío increased the pace. His thrusts grew longer, more decisive. The tip struck my throat and drew filthy, involuntary sounds from me. I felt saliva, tears, the pull in my hair, the pressure of the collar around my neck. Everything together. Everything mingled with the increasingly desperate heat between my legs.

Then he pulled his cock from my mouth and left me gasping, drooling, empty.

“Stand up,” he ordered.

It took me a second to react. He released my wrists and helped me rise. My legs were weak. The contract was still stuck to my damp chest. Darío turned me with my back to him and bent me over the table. My cheek pressed against the wood. One of his hands held the nape of my neck. The other spread my buttocks without consideration.

“I want to see whether you obey when you’re dying to come.”

He brought two fingers to my pussy again and shoved them in. I screamed. Not from pain, but from need. He fucked me with his hand rapidly, striking the inside of me exactly where I was already sensitive—far too sensitive. The wet sound of his fingers going in and out humiliated me because it told the truth better than any words could.

“Look at you,” he said beside my ear. “Gushing all over my table.”

“Yes, Darío,” I babbled.

With his other hand he caught my clitoris between two fingers and began rubbing it in short, precise circles while continuing to penetrate me with his hand. The combination was so intense that I had to spread my legs wider to keep from folding. My orgasm rose suddenly, fierce and immediate.

“Don’t come,” he said just as the spasm began to take me.

I tried to stop myself. I truly tried. I tightened my abdomen, held my breath, bit the wood of the table. But he kept rubbing, kept thrusting his fingers into me with that ruthless precision that seemed designed to take me exactly to the edge and leave me there in pieces.

“Please...”

His hand stopped.

“What?”

My cheeks burned.

“Please let me come.”

He pulled his fingers out and slapped me sharply on the pussy. The blow made my whole body shudder.

“Be grateful you asked. Denied.”

I let out a hoarse, frustrated, almost animal moan. Darío gripped my hip and spread my legs farther with his knee. Then I felt the head of his cock parting my lips, wet with my own arousal and with the saliva from my mouth.

“Now you’re going to take me. And you don’t move until I tell you to.”

He pushed slowly at first. The tip entered, thick, stretching me with a delicious mixture of pressure and relief. I had been on the edge for so long that feeling him enter was almost a good pain, a brutal release. When he was halfway in, he paused to make me endure it.

“Breathe.”

I obeyed, trembling.

He drove all the way in at once.

A clean cry escaped me. My pussy contracted around his cock with a force I hadn’t expected. Both my hands were dug into the edge of the table, my face turned to the side, my mouth open. He remained still for a few seconds, buried inside me, letting me feel how full I was, how open he had me.

“That’s how I wanted you,” he murmured. “Nice and occupied.”

He began fucking me with long, firm thrusts, unhurried. Each time he withdrew almost completely and then drove back in until he struck me deep inside, exactly where my body responded best. I received him with little spasms, soaking him more, squeezing him helplessly.

“Don’t come.”

The order, repeated, turned pleasure into a perfect torture. Because my body was already ready to climax. Every impact of his hips against my buttocks sent my orgasm up my spine. Every tug of the collar, every occasional slap on my burning ass, every insult murmured in my ear undid me further.

“What an obedient pussy you have when it’s held properly,” he said, burying himself to the hilt. “Squeeze for me.”

I squeezed. He released a deep growl and increased the pace. Then they were no longer slow thrusts but hard, powerful fucking, for real. The table creaked. The plastic contract struck the wood beneath my chest. My saliva fell in threads. I could barely hold myself up.

“Count,” he ordered.

“One,” I gasped when he drove all the way in.

“Louder.”

“One.”

The next thrust tore a filthy moan from me.

“Two.”

He fucked me like that while I counted, losing my voice and losing count, because at some point I no longer knew whether I was at eight or twelve; I only knew that his cock opened me, struck me, held me at the exact edge of coming and breaking apart at the same time.

Suddenly he pulled out completely. The emptiness was obscene. I barely had time to protest before he turned me around, sat me on the edge of the table, and spread my legs. I ended up facing him, still wearing my bra, the contract on my chest, my swollen pussy shining with wetness.

He looked at me for a second with a calm that drove me crazy.

“Look at me carefully.”

I did. His cock was hard, wet, glistening. He rubbed it directly between my lips, up and down, smearing me further without entering. I raised my hips out of sheer desperation.

“Still.”

He made me suffer for a few more seconds before penetrating me again. This time from the front, watching my face. He gripped me behind one thigh and opened me wider. He entered deep and began fucking me with a steady rhythm, brutally intimate. From that position I could feel him even more. His pelvis struck my clitoris now and then; every brush was a lash of pleasure.

“Tell me whose pussy this is.”

The answer came out broken.

“Yours, Darío.”

He thrust harder.

“Again.”

“It’s yours.”

He slid one hand between our bodies and began rubbing my clitoris without stopping his fucking. That was when I lost my breath completely. My orgasm returned like a huge black wave, impossible to stop.

“I... I can’t take it...”

“You can take whatever I say you can.”

His fingers moved faster. His cock kept striking me inside, deep and steady. I felt my whole body tense, my legs tremble, my belly closing around an inevitable spasm.

“Ask for it.”

“Let me come, please. Let me come. Please.”

He held my gaze while fucking me harder.

“Come.”

The orgasm split me in two.

It wasn’t gentle or pretty. It was violent, wet, uncontrolled. I came screaming his name, squeezing his cock with savage contractions, shaking from my thighs to my shoulders while he kept thrusting and stretching each spasm until it became almost unbearable. I felt myself truly soaking him, my pussy uselessly clenching around him.

“That’s it,” he growled. “Come all over.”

I was still trembling when he grabbed me by the nape and fucked me a few more times, hard and deep, until his breathing grew rougher. He moved my face slightly so he could look at me better just as he came. I felt him pulse inside me, once, again, several times, releasing his hot cum deep within while keeping his hips pressed against mine.

He remained like that for a few seconds, buried inside me, letting me feel everything: his weight, the heat between my legs, the slow leakage when he finally pulled out.

My chest was rising and falling ridiculously. My legs didn’t respond properly. He watched me breathe, wrecked over the table, and then ran two fingers along the inside of my thigh to gather the mixture beginning to trickle out.

“Look.”

He lifted his fingers before my eyes. My pussy throbbed again at the sight of them glistening.

“Open your mouth.”

I obeyed. He slipped them in slowly. They tasted of sex, of me, of him, of everything that had just happened. I sucked them until they were clean.

“Swallow.”

I swallowed.

Darío adjusted my bra, pulled my panties up to mid-thigh, and then lowered them again, just to remind me that he could do so whenever he wished. That small gesture of everyday possession affected me more deeply than his ejaculation.

“You’ve been evaluated today,” he said as he closed his notebook. “You responded well to pain, better to humiliation, and excellently to denial followed by permission. You have a tendency to beg when you’re on the edge. We’ll make a note of that.”

I laughed between gasps, too vulnerable to hold it back.

“Is that good?”

He wiped a dried tear from my cheek with his thumb.

“For me, yes.”

He helped me down from the table and forced me to kneel once more. I could still feel his cum inside me, heavy and warm, and the awareness of still having it dripping from my pussy filled me with almost unbearable embarrassment.

“Last order of the night,” he said. “You’ll get home, shower, and repeat the breathing pattern I’ll send you. You will not touch yourself. You will not come again. Tomorrow you’ll come prepared to train and to obey better than you did today. If you fail, we’ll correct it. If you comply, you’ll earn more.”

I lowered my head, feeling the contract brush against my damp chest.

“Yes, Darío.”

“Whose are you when you cross that door?”

I raised my gaze. My voice no longer trembled.

“Yours.”

He held my eyes for several seconds, satisfied, and then handed me my dress without a single extra caress, without decorative tenderness, without breaking the tone of what had begun there. I dressed slowly, my buttocks still burning, my pussy sensitive, and my mouth remembering the weight of his cock.

When I left the office, my body was disordered and my mind steeped in a fierce peace. For the first time in a long while, everything was exactly where it belonged: my legs still weak, my breathing still measured, and the contract hanging against my chest like a heavy, obscene promise. I didn’t feel that I had lost anything. Rather, I felt that at last someone had given a name, rules, and an owner to a hunger I had spent years pretending not to understand.
