The Day My Uncle Marcos Learned to Obey Me

Uncle Marcos was my father’s best friend, or so I had always been told. I live alone with Dad ever since my mother left, so many years ago that I can barely remember her. My father works almost all the time, so I grew up with a freedom most girls my age would envy.

That morning, over lunch, Dad told me Marcos was coming to visit us. He had returned from Spain after years away and wanted to stop by and say hello. I wasn’t thinking much about him, but something in my chest flared when I heard his name.

Marcos had always treated me with a tenderness my father didn’t know how to give me. And in the last few years, every time I remembered him, I realized something new: he was handsome. Very handsome. He trains almost every day, so he has a firm body, tanned skin, hard features, and a beard that’s always perfectly trimmed.

When there were a couple of hours left until he arrived, I took a long bath. I put on just a little makeup, going for that effect of not having made any effort, as if his visit didn’t matter to me. I wore very short shorts and a loose blouse, with no bra underneath. I knew it was wrong. I knew he would never do anything. But I wanted him to notice that, with my eighteenth birthday just behind me, I had become a woman.

Let him see how my body has grown. Let his mouth go dry and let him not know why.

At last the doorbell rang. I dabbed a few drops of perfume on my neck and waited for him to come in with my father.

“Uncleee!” I shouted, running to throw myself into his arms.

“Reni!” he answered. My name is Renata, but since I was a little girl he’s called me Reni.

He lifted me off the floor and spun me around in the air. I felt my tits squash against his hard pecs, my already hard nipples rubbing the fabric, and a shiver ran down my spine all the way to my cunt, which suddenly went wet.

“Look at you, how big and beautiful you’ve gotten. You’re a real woman now.”

“Thanks. You look just the same as always, Uncle. Want something to drink?”

“A glass of water, please.”

He sat on the sofa to chat with my father. When I came back with the glass, I caught him turning his head toward me, sliding his gaze down my legs before quickly returning to the conversation, like a child caught stealing candy. I felt a stab of triumph in my stomach. I handed him the water and sat down to listen.

He said he had been away for years for work, but this time he was staying in the city indefinitely. He already had a furnished apartment all to himself. While he spoke with my father, I saw him looking for me with his eyes every so often, as if he wanted to watch me and knew he shouldn’t.

Then Dad’s phone rang. An emergency at work: only something serious would make him leave on a weekend.

“I have to go sort something out, I’ll be right back,” he said, already on his feet.

“Should we just see each other another day?” Marcos offered, and the mere idea disappointed me.

“No, man, half an hour at most. Can you wait?”

“No problem, I’ve got the day off,” he replied, and inside I celebrated.

“Perfect. Reni, tell your uncle how things are going at university. When I get back, the three of us will go out to eat.”

“Sure, Daddy.”

The door closed. And suddenly I had him all to myself.

***

“So how are things going with your studies, Reni?” he asked, leaning back on the sofa.

“Very well, I have the best grades in the program.”

“I’m glad to hear that.”

“I think my only problem is with boys,” I let slip, playing with the hem of my shorts.

“What’s wrong, are you looking for a boyfriend?”

“No, Uncle. It’s just that sometimes they get pushy, they bother me, and I don’t know how to make them stop.”

“Have you talked to anyone at the university?”

“Yes, but they don’t do anything. And since I don’t know how to fight or defend myself, I can’t get rid of them.”

I saw his jaw tighten. Exactly what I wanted.

“Look, I practiced martial arts for many years. I could teach you a few things.”

“Yes! Please, that would help me so much.”

My plan was working perfectly. I wanted everything to turn physical between us, and he was serving it up to me on a platter. He started showing me how to strike, how to dodge, a few holds and how to break free from them. I loved it when he pinned me so I’d have to get free: his hands held me, his fingers brushed my tits by accident, and I pretended to concentrate on the technique.

“This is going to help me a lot, Uncle. But what do I do if the other person is much stronger than me?”

“Then you go for the weak points.”

“Which are, exactly?”

“The neck, the eyes, the ears… and well, you know, down there.”

“Down there?” I asked, opening my eyes wide, pretending to be innocent. He shifted, uncomfortable.

“Yes, Reni. You know. The testicles.”

“Oh, right,” I said, biting my lip so I wouldn’t laugh. “And does that really work?”

“It works. It’s the most effective thing there is.”

“I tried it once and it didn’t work for me. Do you think you could teach me to do it properly?”

I could tell he was nervous, but he agreed anyway. He showed me how to throw a front kick and practiced with me, marking the movement slowly.

“Can I kick you so I can see if I’m doing it right?”

“Ha, you’re crazy, Reni. You’ll leave me without descendants.”

“Aww, come on, Uncle. I’m not going to hit you hard, I just want to make sure I’m aiming right.”

“I don’t think that’s a good idea.”

“Pleeease,” I said, putting on a sad little face, eyes big, lower lip pushed out. I had him.

“All right. But gently, okay?”

He stayed standing, with his hands clasped behind his back. I gave him a tap so light it barely brushed his crotch, just enough to feel the bulge. It was electric.

“There, good technique.”

“No! It isn’t working right, your jeans are too hard, they won’t let me kick the way I want to.”

“You don’t expect me to take them off.”

“...”

“I’m not taking them off, Reni. What if your dad comes back? He’d think all kinds of things.”

“Dad takes forever, his office is way over there. And besides, there’s nothing wrong with this, you’re teaching me how to defend myself!”

“I don’t know…”

“We won’t tell anyone. Please, Uncle. It’s been so long since I saw you, I missed you so much. Are you really going to refuse your favorite niece this?” I finished with the same little sad face.

The blackmail worked. He let out a sigh of defeat and started pulling his pants down. His white underwear framed a shape that left me breathless. He wasn’t aroused, and yet it was imposing: it looked as if the fabric could barely contain that thick, pendulous cock, outlined to one side, with the heavy bulge of his balls right beneath.

“Okay, do it, Reni. Same as before.”

“Here I go. But kneel down, please, you’re too tall.”

“No boy is going to kneel so you can kick him.”

“I know, but no boy is as tall as you. The guys my age are about my height. I just want to practice the motion.”

“Fine, but do it already.”

Having that huge man kneeling in front of me was a delicious feeling. It was so easy to convince him to do anything I wanted. I got into position.

“One…” —I barely brushed his bulge with the tip of my foot. He was glancing toward the door out of the corner of his eye, uneasy.

“Two…” —I repeated, this time lifting the bulge a little with the instep, watching him sway when I pulled my foot back.

“Three!” —I threw the kick with all my strength. I felt the impact dead on, the jolt of his balls inside the fabric. Marcos doubled over, grabbed his crotch, and fell onto his side on the floor.

“Ow, Reni! You hit me so hard!”

I couldn’t believe it. One blow had been enough to drop that strong man. I felt a tingle between my legs, a throb in my clit, a rush of power and desire that soaked my panties. I wanted to slip my hand under my shorts and rub myself right there, but I settled for bringing my hands to my chest and pretending to be horrified.

“Sorry, Uncle! I didn’t mean to, it was an accident,” I said, kneeling beside him.

“It’s okay, Reni, I know you didn’t mean to.”

“Let me see if you’re all right.” —I laid my open hand over his, which was shielding his genitals.

“I’m fine… it hurts, but it’ll pass,” he said, his voice tight.

“Let me rub it at least, I feel guilty.” With my other hand I gently moved his away and placed my palm directly over his crotch.

He froze. He wouldn’t take his eyes off my hand, breathing hard while I pretended to soothe his pain. Under the fabric I felt the cock starting to swell again, filling out slowly, growing heavier against my palm. But I could no longer pretend. I wanted to feel it for real.

***

I closed my hand and started to play, slowly, watching his breathing speed up. I squeezed his balls over the fabric, moved them inside the soft pouch of his briefs, and with my fingers ran along the full length of the cock growing and growing under my hand.

“Does that feel good, Uncle?”

“Yes… but don’t squeeze so hard, please.”

“Like this? —I asked, clenching my fist tightly around his balls.

“Don’t do that, Reni!”

“Sorry, Uncle, don’t be mad. I thought it didn’t hurt anymore and I was just playing,” I said in the sweetest, saddest tone I could manage.

“I’m not mad. You just startled me.”

“I’m going to take this off so I can massage you properly and make you feel better,” I announced, tugging down his underwear.

“No, Reni!” he reacted, grabbing my wrist.

“Let me heal you, don’t be stubborn,” I insisted, squeezing his balls again over the fabric.

He gave a groan and, defeated, let me finish. I flung the garment onto the sofa and uncovered him: the cock sprang free, fully erect, thick, with veins running along the shaft and the head swollen and shiny, already damp with pre-cum at the tip. Below, the heavy balls hung taut, red from the rough handling. A beautiful sight, now entirely at my disposal.

I wrapped my hand around the base and started to pump slowly, up and down, feeling the skin slide over the hard shaft. With my thumb I spread the drop beading at the tip, and he let out a hoarse moan, biting his lip. I alternated caresses along his length, firm squeezes at the base, gentle fingers circling his balls and weighing them in my palm. He kept glancing toward the door, tense with the fear that my father might return, but pleasure was winning over him: his breath came in ragged bursts, his abs tightened every time I slid my fist over his glans.

“Reni… no… this isn’t right…”

“Shhh,” I said, putting a finger to his lips without stopping the handjob. “You’re teaching me. That’s all.”

When I felt him completely surrendered, I pulled off his T-shirt. He no longer resisted. I ran my tongue along his neck, bit his earlobe, lowered my mouth down his chest to one of his nipples and sucked it while I kept pumping his cock with my hand. He shuddered all over. It was time to raise the stakes.

“Uncle, I want to keep practicing. Pretend you’re touching me and I’m defending myself.”

“Mmm, I don’t know, your father shouldn’t be long.”

“It’ll be quick. You said you’d help me. I’ll turn around and you start from behind.”

I turned my back to him. Naked, he placed one hand on the small of my back and slid it upward until it circled my waist. He put the other hand on me and held me at the sides. Feeling those strong hands taking possession of me was sublime. Slowly they moved down to my ass, first timidly, along the sides, until his breathing grew heavy and he started squeezing hard, sinking his fingers into the flesh of my cheeks over the shorts.

I was supposed to “defend myself,” but I didn’t want it to ever end. He pressed closer to me. His hands moved up and covered my tits. With no bra on, I felt every one of his fingers through the thin fabric, how he pinched my already hard nipples until it tore a gasp from me, and his cock driving between my ass cheeks, pushing against the shorts. I had never been so aroused in my life. My cunt was dripping, I could feel my panties glued to me, soaked through.

Marcos pressed his lips to the nape of my neck, licked my skin, and slid one hand down my belly. I let him. He slipped it inside my shorts, moved the waistband of my panties aside, and found me flooding. He gave a groan in my ear when his fingers sank into my wet cunt.

“God, Reni, you’re soaked,” he murmured, his voice rough.

“All for you, Uncle,” I answered, pushing my ass back to rub his cock between my cheeks.

His fingers started playing inside me: two of them, slipping in at once, while his thumb found my clit and pressed it in slow circles. My knees nearly gave out. I braced myself on his forearms while he finger-fucked me, deeper and deeper, curling his fingers inside me and scraping that spot that made me see lights.

I couldn’t take it. I turned around, took his face in my hands, and made him bend down so I could kiss him. I felt a mix of love and desire burning me from the inside. He squeezed my ass again while our tongues searched for each other, tangled hungrily, while I bit his lip and sucked his saliva. I took one hand to his balls and started massaging them, weighing them, barely squeezing; with the other I grabbed his cock and jerked him slowly, feeling it throb in my fist. He was getting hotter and hotter, pushing his hips against my hand, asking for more.

I shoved him away and knelt in front of him. It was at face level, pointing at me, hard, thick, with that vein pulsing along the shaft. I stuck out my tongue and licked the head from bottom to top, tasting the salty fluid that was leaking out of him. Marcos let out a muffled “fuck” and buried his fingers in my hair. I ran my tongue all the way along his length, from the balls to the tip, soaking it with saliva, and then I took the whole thing into my mouth. As much as I could. His cock reached the back of my throat and made my eyes water. I started sucking him hungrily, moving my head up and down, lips tight around the shaft, sucking his glans when I got to the top with a wet sound. Saliva dripped down my chin, wetting his balls. With my free hand I squeezed them, tugged them gently, while with the other I pumped the base of his cock in time with my mouth.

“Reni… not like that… I’m going to come…”

Exactly what I wanted to hear him say. I pulled his cock out of my mouth with a pop, kept pumping him with my fist, and flashed him a wicked smile from below. Then I moved away for a second and, without warning, slammed my knee hard into his crotch, right into his swollen balls. He dropped to his knees, sliding his hands down my legs while he fought for breath, his cock still hard, throbbing between his thighs.

“Kiss them,” I ordered.

He didn’t hesitate. He started kissing my thighs while I played with his erection using my foot, flattening it against his stomach, brushing his balls with my toes. He was in a trance: I had an imposing man kneeling there, kissing my legs, obeying every word. And at the slightest sign of rebellion, one hit down there was enough to put him back in his place.

“Higher, Uncle. Take off my shorts.”

He pulled them down along with my panties, soaked through, and left them at my ankles. I stayed in my blouse, my cunt exposed at the level of his face. He stared at my trimmed pubic hair, my swollen, shiny lips, and a moan escaped him.

“Eat me out,” I ordered, and I shoved his face between my legs.

Marcos drove his tongue into me without hesitation. He ran it from top to bottom, from perineum to clit, long, broad, slowly, tasting me. He pried my lips apart with his thumbs and buried himself there, sucking me, licking me inside, pushing his tongue into my wet cunt until my knees went weak. Then he went up to my clit and swallowed it, sucking it with his lips, teasing the tip of his tongue while two of his fingers went in and out of me. I grabbed his hair, pushed his face against my cunt, rubbed myself against his beard, against his mouth. The trimmed beard scraped my lips in a delicious way, leaving my skin red and sensitive.

“Like that, Uncle, like that, don’t stop…”

He didn’t stop. He sucked and devoured me as if his life depended on it, and I felt everything building in my belly, the pressure growing, pulling from the inside. I dug my nails into his scalp and came all over his mouth, climaxing in spasms, squeezing his face with my thighs while I poured onto his tongue. He swallowed, licked me clean, never letting go of me, while I trembled over him.

I couldn’t hold back any longer and threw myself on top of him. Marcos fell onto his back, propped against the sofa, and we kissed desperately. I could taste myself in his mouth, salty and mine. I rubbed my soaked cunt against his erection, sliding up and down the whole shaft, wetting it completely with my fluids, until I grabbed his cock with my hand, settled myself over the glans, and lowered myself slowly, spearing myself on him.

A muffled cry escaped me. He filled me completely, every centimeter opening me from the inside, until I was seated with his cock buried all the way in. Marcos groaned and dug his hands into my hips, trembling.

“Fuck, Reni, you’re so tight…”

I started moving, up and down on him, riding him slowly at first, feeling his cock slide out and in again, wet with me. I braced my hands on his chest and sped up, bouncing my ass against his thighs, my tits jostling inside my blouse. He tore the blouse off over my head and caught my nipples with his mouth, sucking them, barely biting them, while I rode him furiously. The sound of our skin slapping together, the squelching of my wet cunt swallowing his cock, my own moans that I no longer controlled: it all filled the living room. I ground myself against him, out of my mind, feeling him slam into my depths with every downward motion, until pleasure exploded again in an intense orgasm that left me limp and trembling in his lap.

***

I felt like I was in heaven, but I didn’t want to leave him half-finished. I got off him, still shaking, and sat on his abdomen, with my back to his face, facing his feet. My cock was left behind me, hard, pointing at the ceiling, shiny with my juices. I leaned forward, grabbed it with both hands, and started jerking him off, alternating it with the occasional sudden slap on his swollen testicles. He took me by the waist and squeezed my ass, pried it open with his thumbs to look at my exposed cunt and ass, his tongue slipping out to lick me from below. With every slap to the balls he shuddered and moaned, digging his fingers into my skin.

I ran my fist firmly along the shaft, up and down, twisting my wrist when I got to the glans and spreading over the tip the mix of saliva and fluids that coated it completely. Now and then I bent down to lick the head, to take it into my mouth for a moment, and then I went back to pumping it. When I lowered my free hand, I caught his balls and tugged them, squeezed them just as my fist slid up his cock. Marcos writhed beneath me, gasping, his hips pushing upward, seeking my hand.

“Reni… I’m going to…”

“Come, Uncle. Come for me.”

I gave his balls a sharp slap just as I squeezed the glans, and he exploded. After a few seconds his muscles suddenly tensed. I felt him harden even more in my fist, hold his breath, and finally let go. The first rope of semen shot out, thick, and landed on my hands, on my belly. More followed, hot spurts gushing out and soaking his cock, his balls, my fingers. I slowly eased the pace, milking him, drawing out the last drop, feeling him keep jerking every time I ran my fist over his sensitive glans. I brought a finger to my mouth and licked it: thick, salty, warm. I smiled over my shoulder while licking my lips. Marcos moaned at the sight and sank back, still beneath my body.

Then he did something that surprised me. He pulled me back, wrapped his arms around my stomach from behind, and rested his head on my back. I crossed my arms over his. He lifted his face and kissed my neck, slowly, tenderly. We stayed like that for a long while, in silence, with his cock softening slowly against my lower back, still sticky.

But both of us knew my father could return at any moment. We straightened up. Marcos looked for his underwear, and I, quicker, sat on the sofa and took it before he could.

“I want us to practice again another day, at your apartment,” I said, holding the garment out of his reach.

“I love you, Reni, but I think that’s a very bad idea.”

That answer annoyed me. I reached out, grabbed his still-sensitive balls, and pulled slowly toward me. He leaned in immediately, trying to make me let go.

“I want you to stop being so scared and so disobedient,” I said calmly, squeezing them a little harder. “Nothing is going to happen, nobody will find out. I’m eighteen years old, I’m an adult now. There’s nothing to fear.”

“But you’re my niece…” he protested, and I squeezed a little harder.

“…”

“All right,” he gave in at last, his voice breaking.

Only then did I give him back his clothes. He got dressed, went to get paper to clean the floor, and when we were done we sat in the living room talking as if nothing had happened, so my father wouldn’t notice absolutely anything when he got back.

I was already thinking about the next lesson.
