My Stepmother’s Trans Partner Taught Me to Obey

The library in the house always smelled of old wood and secrets no one dared to name. That afternoon, though, what dominated the air was Marcela’s perfume. Jasmine and something colder underneath it, an elegance that, at twenty-six, still made me feel like the boy begging for her approval. My father had been in Singapore for half a year closing deals, and his absence had only made the void Marcela filled with quiet, total authority even larger.

—Sit down, Damián —she said without lifting her eyes from a stack of papers.

Her voice was silk with an edge. It wasn’t an invitation. I sat in the leather armchair in front of the mahogany desk. She wore a dark dress that hugged curves I had learned to glance at since adolescence, with a mixture of guilt and desire I had never managed to extinguish. She wasn’t my mother. She was the woman who had married my father when I was sixteen, and that, in theory, should have been enough to protect me from wanting her. It wasn’t.

—I’ve heard stories about your distractions —she went on, setting the documents aside and pinning me with green eyes that never forgave weakness—. You think that because your father isn’t here you can squander the family name on one-night adventures. I didn’t raise you to be an ordinary man, Damián. I raised you for this house.

Before I could stammer out an apology, the door opened.

Renata came in. If Marcela was ice, she was red-hot metal. A trans woman of a beauty that didn’t seem real, nearing forty, tall, with heels that clicked over the parquet like a sentence being carried out. Her body combined full curves with firm shoulders, all wrapped in a burgundy tailored suit that screamed power. She was Marcela’s business partner, but the way they looked at each other when she entered suggested a pact much older and much darker.

—Is this the pup you were talking about? —Renata asked, circling my chair.

I felt her gloved hand brush the back of my neck. The contact raised gooseflesh all over my skin. Her voice was a deep contralto that seemed to claim my body before touching it.

—It is —Marcela replied, standing to take her place beside me—. He has the vigor of youth, but no direction. He thinks he’s a man because he has strength in his arms. He doesn’t know what it is to truly surrender.

Renata stopped in front of me. She lifted my chin with two fingers wrapped in fine leather. Her face was a hand’s breadth from mine, and I could smell her perfume: sweet tobacco and amber.

—You have beautiful eyes —she murmured, raking her gaze over me until I felt naked—. And a body that’s begging to be shaped. Marcela and I decided your education was left unfinished. Your father taught you to inherit. We’re going to teach you how to belong.

I should have left then and there. I didn’t.

—Today your reeducation begins —Marcela pronounced, resting a firm hand on my shoulder—. You’re going to discover that the greatest pleasure for a man of your bloodline is not giving orders. It’s being the surface others write their will upon.

***

The walk from the library to the house’s private wing was a slow procession. I walked between them, feeling their presences like a field you couldn’t step out of. Marcela, on my right, kept a possessive hand on my arm. Renata, on my left, let the fabric of her suit brush my shoulder at every step, reminding me of her height and strength.

Marcela’s room looked less like a mother’s bedroom than a queen’s chamber. Heavy velvet curtains shut the world out. The jasmine now mixed with something harsher: the smell of leather Renata began pulling from a designer briefcase.

—Take off your shirt —ordered Marcela, sitting in a high-backed chair and crossing her legs with an elegance that stole my breath.

My fingers trembled at every button. When the garment hit the floor, Renata came up behind me. I felt her body, taller than mine, pressing against my back. Her hands traveled over my shoulders and down my chest, testing the resistance of my skin. One of her gloved fingers found my right nipple and pinched it without warning until a gasp tore out of me. The other hand slid flat to my belt, followed the line of the fabric, and squeezed my already-hard cock through my pants, weighing it like merchandise.

—An excellent physique —she told Marcela, speaking into my ear as she kept squeezing—. Shame it’s been wasted on nonsense. We’re going to give it purpose. And look at this, Marcela: he got hard from just a nipple pinch. This pup has the body of a fucking slut before he even knows it.

She looped a black leather collar around my neck and tightened it just enough that every time I swallowed I was reminded who held the control. The click of the buckle sounded like a cell door closing.

—On your knees, in front of her —Renata said, pushing my shoulders down.

I dropped before my stepmother. From the floor she looked like an ancient figure, untouchable. Marcela caressed my cheek with a tenderness that hurt before closing her hand over my jaw and forcing me to look at her.

—Look at yourself. You’re trembling with fear and desire at the same time —she whispered—. Your father built all this on other people’s will. I’m going to build my pleasure on yours.

Renata undid her suit and revealed black lace lingerie that contained a powerful, sculptural body charged with an energy that made me feel tiny. The lace bra barely held two large, firm breasts, and beneath the lace panties the unmistakable weight of a sleeping cock was outlined against her thigh. Every trace of conventional masculinity was eclipsed by her, and yet that bulge, hidden and obvious at the same time, was the most obscene promise of everything that was about to come.

—Today you learn that a body like mine and the authority of a woman like her are the only two laws you’re going to obey —she said, opening a small bottle of oil—. Strip completely. I want Marcela to see how her pup surrenders.

***

I stripped off the rest of my clothes under their cold gazes. I was exposed completely, my arousal betraying me without mercy: my cock was pointed at the ceiling, swollen, with a thick drop of pre-cum hanging from the head. On my knees between the woman who knew all my secrets and the one promising to push every limit, I felt something ancient break inside me, and I didn’t want it repaired.

Marcela leaned in, collected that drop with the tip of her thumb, and placed it on my lips without a word. I licked it because I knew that was what was expected. She smiled.

—Suck your own juice off your lip, Damián. It’s the first of many humiliating things you’re going to swallow tonight.

Renata lowered one hand and grabbed my entire cock with her gloved palm. The cold leather against hot flesh drew a moan from me so sharp I was ashamed.

—Listen to him —she murmured, stroking me up and down with calculated slowness—. He’s already on the verge of cumming and we haven’t even started. We’re going to have to teach him to last, Marcela, or this will be a waste.

She pinched just below the head with two fingers and cut off the flow at once. My whole body jolted in a false discharge, a denied orgasm that tore a sob from me. She left me there, throbbing, not cumming, my balls clenched and a dull burn in my lower belly.

—Face down, on the rug —ordered Marcela, rising with a short riding crop in her hand.

The cold Persian wool against my chest was a violent contrast to the heat rising inside me. My cock, crushed against the wool, throbbed with every breath. I heard the hiss of the crop before I felt the sharp, precise blow across my hip. The pain was an electric spark that made me arch my back, but Renata’s heel came down on my neck and forced me back to the floor.

—We told you not to move —she murmured—. Every gesture without permission gets paid for. Here your body is an extension of what we want.

Renata knelt between my legs and poured the oil between my ass cheeks. The warm liquid slid slowly down to my hole and kept dripping to my perineum and balls. Her hands were large, warm, firm. She began massaging my cheeks, parting them with her thumbs so my ass was opened and exposed to Marcela’s gaze.

—Look what a tight hole your stepson has —she told Marcela, while one thumb began rubbing the clenched fold—. Pink, virgin, unused. What a shame for an ass like this to have gone to waste for so many years.

—Open it slowly —Marcela replied—. I want to see his face when he understands what it’s really for.

Renata’s thumb began to enter. At first it was only the tip, circling, loosening the muscle. I clenched my teeth against the rug, between shame and a strange surge of pleasure crawling up my back. When the finger slid all the way in, I dug my nails into my palms. It was a sensation of total invasion, and the humiliation of being opened like that, in my own house, by my father’s partner, made it unbearable and delicious all at once.

—Look at him, Marcela —she said, curling the finger inside me until she found a spot that made me howl into the wool—. Look how his heir’s pride falls apart the second he feels real command. His ass is moving on its own already, begging for more.

—Delicious —Marcela replied, leaning down to stroke my hair—. Damián, this pleasure, the pleasure of being taken, is the only one we’re going to allow you from now on. Your strength is yours. Your submission is ours.

Renata pulled out her thumb and added two fingers, index and middle, sinking them to the knuckles. She scissored them open, stretching me, then started pumping in a cadence that made me lose track of where I was. Each thrust drew a moan from me, deeper and more animal each time. My erection, flattened against the rug, rubbed helplessly against the wool, and I knew that if this kept up I’d cum on the floor like a teenager.

—Don’t even think about leaving a stain on my rug —Marcela warned, as if reading my thoughts. She crouched, slid a hand under my hip and lifted my cheeks to separate me from the floor—. If you’re going to cum, you’ll cum when I say so. Not a second before.

Renata added a third finger. The stretch drew a long groan from me. She moved her fingers deep, setting a slow rhythm, stopping whenever she felt me getting close to the edge. She was training me, opening me like someone preparing a mold for what would come next.

***

—On all fours —ordered Renata, yanking her fingers out and leaving me with a hollow ache that made me pant.

I obeyed, trembling. My ass pulsed, open, begging to be filled. Marcela knelt before me, at the level of my face, and held my cheeks in both hands.

—Don’t close your eyes —she said—. I want you to see in my gaze the exact moment you stop being the house’s son and become ours.

Behind me I heard the briefcase open and a metallic sound. Renata was in no hurry. I felt the cold of polished steel rest against my freshly worked hole, and the thermal contrast tore a moan from me. It was a metal dildo, heavy, with a thick head that made itself known the moment it was pressed against me. I tried to pull away, but Marcela dug her nails into my cheeks.

—Don’t even think about it —she whispered, deadly—. You’re in my room, under the command of my best ally, surrendering what you should never have surrendered. Enjoy the fall.

Renata pushed with ruthless firmness. The metal invaded me slowly, stretching every fiber while my eyes stayed locked on my stepmother’s. I felt the head force its way in, felt the cold moving through me, felt the air leave me in a long moan. Seeing her satisfied while Renata claimed me was the final blow to what little will I had left.

—That’s it. Moan for us —Renata murmured, moving in a slow, deep rhythm, pulling the metal cock almost all the way out and driving it back in with a clean thrust—. Feel the steel marking you. Feel the strength of a woman who knows exactly how to break a man like you.

Each thrust pushed me forward, almost until I brushed Marcela’s lips, and she never backed away. She made me open my mouth and pushed two fingers between my teeth, forcing me to suck them to the rhythm of Renata fucking me with the metal. Saliva dripped down my chin. She enjoyed my degradation, seeing the heir to the fortune reduced to a trembling, obedient mass sucking fingers on one side and taking steel on the other.

—You’re ours —she told me in my ear—. Your father will never know his greatest treasure belongs to us. You’re the dirtiest secret in this house, and you’re going to learn to love every second.

Renata sped up with the metal dildo. She buried it deep, twisted it inside me, slammed it against my prostate again and again until my whole body shook and a steady thread of clear fluid leaked from the tip of my cock. A small puddle formed on the rug between my knees. I couldn’t close my mouth, couldn’t close my eyes, couldn’t stop the moans.

***

Pleasure and pain had intertwined until I could no longer separate them. Renata ripped the toy out, making me scream, and forced me to sit back on my heels. My ass stayed open, throbbing, empty. She removed her lingerie and stood completely exposed: an imposing silhouette, a woman who filled the room with her very presence. And there, between her thighs, there was no longer any concealed bulge, but a thick, erect cock hanging heavy, dark, veins standing out and the head shining.

—Marcela thinks you need humility —she said, stepping toward me and grabbing her shaft in her hand to bring it up to my face—. I think you need to understand who your true owner is. Open your mouth.

I opened it. She didn’t wait. She shoved her cock all the way in with a single thrust, not giving me time to breathe. I felt the head hit the back of my throat and the gag reflex rose at once. She grabbed my hair with both hands and started moving my head to her rhythm, fucking my mouth like it was just another cunt.

—That’s it, pup. Swallow my cock. It’s the only thing that mouth of yours, rich boy, is good for.

Marcela positioned herself behind me. The crop came down on my back every time my rhythm faltered, burning lines that contrasted with the heat in front of me. Each lash made me moan around Renata’s cock, and each moan vibrated around her shaft and made her growl with pleasure.

—More devotion —Marcela demanded, the crack of the crop underscoring the order—. You’re sucking the cock of a queen. Do it like your life depends on it, because your pleasure certainly does. Tongue out for her balls, Damián. Lick them one by one. Let her know you adore them.

Renata yanked her cock out of my mouth and smashed my face against her balls. I stuck my tongue out as ordered and licked them, sucked them, adored them with my whole tongue, while she jerked herself above my forehead and let a trickle of spit and pre-cum fall into my hair.

—Look at his face —Renata panted, burying her fingers in my hair—. There’s nothing left of the arrogant boy who walked into the library. All that’s left is this toy drooling over my balls.

—Exactly what I wanted —Marcela replied, dropping the crop to stroke the marks she herself had left—. A blank canvas to write our rules on. Pain is only the wrapping on the gift, Damián.

Renata shoved her cock back into my mouth and rammed it down my throat again. This time she held it there, choking me, until tears ran down my cheeks and a thick line of spit escaped the corners of my mouth.

—Swallow —she ordered—. Swallow around my cock, with your throat. Milk it the way you need to learn to do.

***

—On your back —ordered Renata—. I want you to watch us while we decide who pushes you to the limit tonight.

I lay down. The position was the most vulnerable: legs spread, ass still open from what had come before, cock erect and pointing toward my own navel, my whole body offered up to the two women presiding over my ruin. Standing over me, they looked like two figures out of a dream I had never asked to have.

Marcela took off her dress and revealed a body over fifty that defied any standard, firm and wise in every curve. Her breasts hung full, nipples dark and hard. Her cunt, shaved and shining, was already swollen and wet. She straddled my shoulders, knees on either side of my head, and lowered herself slowly until her pussy hovered an inch from my mouth.

—Stick out your tongue, Damián. Eat your father’s woman. Eat me like the dirty boy you always were beneath the surname.

I stuck out my tongue and buried it between her lips. The taste hit me, dense, salty, feminine, and tore a groan from me of pure animal desire. I found her clit with the tip of my tongue and started licking it in circles while she braced both hands on the headboard and ground herself against my face without the slightest gentleness.

—That’s it, deeper. Take it all. Fuck me with your tongue, pup. That mouth belongs to me from today on.

Renata adjusted nothing at her waist; she didn’t need a harness, and she positioned herself between my thighs with her own cock in her hand, hard and slick with oil. She lifted my legs until they rested on her shoulders and looked down at me with a cruel smile.

—Think you can handle both of us? —she asked, pressing the head against my hole—. Think this little heir’s ass can take a real cock?

The first thrust had no subtlety. It entered me with such force that my body arched, but Marcela’s weight kept me anchored to the bed. Renata’s cock-head opened me despite the oil and the fingers and the metal before it; I felt a brief burn, followed by a hot, living fullness very different from steel. I screamed against Marcela’s cunt and the scream reached her as a vibration that made her push harder against my face.

—Take it all —Renata whispered, sinking to the root in one short shove—. All my cock inside you. Like this. Now you’re really ours.

It was total saturation: my mouth occupied by my stepmother’s taste, my ass claimed by Renata’s cock, and both women’s hands moving over me without rest. I was betraying my father with the two people I trusted most, and the vertigo of that betrayal made me shake to the bone.

—Harder —Marcela ordered, shifting just enough to look—. Break him. I want every time he closes his eyes, he sees this moment.

Renata sped up. Her thrusts were deep, rhythmic, brutal, and her body slammed into mine with a wet slap that echoed through the silent room. Her balls struck my perineum with every downstroke, and with each hit she tore a sharper moan from me. I was the link between them, the object that allowed their complicity to reach a point neither would have achieved alone. Marcela lowered herself back onto my face, ground her cunt against my mouth, and now also slipped a finger into the corner of my lips to keep me more open.

—Marcela! —I moaned, but she covered my mouth with her gloved hand.

—Don’t call her like a son —Renata growled in my ear, never stopping her fucking—. Call her your owner.

—My owner —I repeated like a prayer, my voice broken, against the wet cunt sinking into my face—. My owner, my owner, my owner.

Marcela came over my mouth without warning. I felt the tremor run through her from the thighs up, felt her cunt clench against my lips, felt the warm rush run down my chin and my neck. She stayed there a few seconds, breathing hard, marking my face with her pleasure, before slowly getting off.

***

My senses started to fail. The burn on my back, the pressure of Renata’s cock still moving inside me, the recent weight of Marcela on my chest, the taste of cunt on my tongue, all of it formed a whirlwind that ripped away my sense of time. Then Renata stopped abruptly and withdrew, leaving me open, throbbing, my hole already loose and hungry. Marcela stood up, recovering that sovereign verticality that intimidated me so much.

—Look at his face —she said—. He’s about to break, and his body still wants an exit. We’re not going to give him one so easily.

Renata took a small steel cage from the briefcase. Before I could protest, she enclosed my cock and balls inside it with a deftness that betrayed how many times they had done this before. I felt it squeezing me, still hard, against the cold bars, and I knew I wouldn’t even be able to grow any further without pain. The click of the lock was the sound of my sentence.

—From now on, your orgasm doesn’t belong to you —she declared, tucking the key into Marcela’s cleavage—. You’ll only get out of that when you’ve served us to the point of exhaustion.

They forced me to kneel again. The frustration of feeling desire burning in me with no way out, my cock trying to get harder inside the metal and only finding pain, pushed me into utter desperation.

—You’re going to watch us enjoy each other —Marcela pronounced—. You’re going to be the spectator of the two women who own you. And if you dare touch that steel, what happened today will seem like child’s play.

I watched them give themselves over. Marcela lay on her back on the bed and Renata climbed on top of her. She spread her thighs and buried her cock in Marcela’s cunt with a single blow, drawing a long gasp from her. She rode her there, in front of me, with a force and technique that made me understand why they were partners in everything. Marcela grabbed her ass and pushed her deeper. Renata bit her nipples, licked her neck, whispered obscenities in her ear. Their bodies rocked in perfect rhythm, sweaty, golden in the lamplight, and the slap of skin against skin filled the room.

—Look at me, Damián —Marcela said without stopping beneath Renata—. Look at who’s fucking me. Look at what your father never gives me. Look at how I enjoy her.

I, caged, burned without being able to do anything. My cock throbbed inside the metal in a useless attempt to react. Tears fell from me out of sheer frustration while I watched them cum, first Marcela with a deep cry, then Renata with an animal growl that emptied her whole body inside my stepmother’s cunt. I was a spectator in my own sanctuary, reduced to nothing, watching them celebrate their domination with semen running down the inside of Marcela’s thigh.

—Come here —she called me, opening her legs—. Come clean what Renata just left inside me. That’s your reward for holding out, pup. That, and nothing else.

I crawled over. I buried my face between her thighs and stuck out my tongue. I licked Renata’s warm semen straight from my stepmother’s cunt, swallowing what fell into my mouth, tasting the mix of both of them and her sweat. Marcela held my head with both hands and forced me to lick every last trace. Renata, kneeling beside us, gave my reddened ass soft pats.

—Good boy. Drink it all. That’s how you learn.

***

After a time I couldn’t measure, Renata drew away from her and fixed on me eyes charged with dark electricity.

—He’s had enough torture —she said—. The pup knows his place. It’s time to let him break all the way.

Marcela nodded with a smile I won’t forget. She took the key from her cleavage and handed it over with a ceremonial gesture. Renata knelt in front of me and, with a slowness that made me sob, opened the lock. She removed the metal slowly, piece by piece, and my cock sprang free, swollen, purple, throbbing with every pulse of my heart. The release was almost as intense as an orgasm, but they still didn’t let me move.

—You’re not cumming on your own —Marcela declared, standing behind me and holding my arms back—. You’ll do it while Renata claims you one last time and I remind you of the only truth in your life: that you’re ours.

They made me kneel with my chest down, ass raised and arms held behind my back by Marcela’s firm hands. Renata positioned herself behind me. She pressed the head against my hole and this time there was no oil or preparation: she entered with the savage urgency of her own body, and though my ass was already taking her, the position and force made me howl into the rug.

—Scream all you want —she panted, gripping my hips—. This house belongs to your stepmother, and she chose for you to scream for us.

She started fucking me with devastating rhythm. The head of her cock slammed into my prostate every two thrusts and made me see lights. My cock, free for the first time in hours, swung between my thighs, dripping nonstop, with no one touching it yet. Marcela released one arm, reached under my body, and finally grabbed it. She began jerking me off with a slow, precise technique only years can give, synchronizing every movement of her fist with Renata’s thrusts.

—Feel it, Damián. Feel how my hand works in the same rhythm her cock fills you with. Feel that you don’t even cum for yourself. You cum when and how we decide.

The betrayal of my father, the surrender to the trans woman who had conquered me, my tongue still stained with another man’s semen, my hole already claimed, my stepmother’s expert hand pumping my cock, all of it collided into one unbearable point. I felt the orgasm rise from the soles of my feet, a shudder I had never felt in my life.

—Now —Renata shouted, driving the pace to the impossible, burying her cock to the root again and again—. Cum for us! Feel who your owners are!

I screamed. It was a tearing scream that rang through the house’s walls, the end of my old identity. My cum came out in long, thick jets over Marcela’s hand and the rug beneath me. At the same time I felt Renata cum inside me, with a growl that vibrated in her chest and with her cock throbbing against the walls of my ass as she filled me with a wet heat that stayed inside me even after she pulled out. Marcela lifted my hand to my mouth, soaked with my own seed, and forced me to lick it all.

—Swallow —she whispered—. Your semen belongs to us too. Nothing of you is lost. Nothing of you is yours.

The climax left me empty, trembling in their hands. As I collapsed, I felt Marcela’s lips at my ear and Renata’s arms holding me, with my cock still limp and dripping between my thighs.

—Welcome to the family —she whispered—. The most valuable inheritance is the one paid for with your will.

I lay in silence on the rug that had witnessed my transformation, my mouth tasting of cunt and semen, my ass open and dripping, my cock defeated against my thigh, and the crop marks burning softly on my back. I was no longer an heir. I was a devotee, claimed by one woman’s maturity and the other’s power. And I knew, as the morning sun began filtering through the curtains, that I would never again want to be free.
