What Happened on the Rooftop with My Brother’s Friend

I was never the kind of girl who throws herself at the first man who smiles at her. I say that honestly, because what I’m about to tell still feels unbelievable even to me. I was twenty-six and living a pretty quiet life: work, home, Sundays with the family. But that night something inside me came loose, like a knot I’d been tightening for months without even noticing.

It all started when my older brother invited his best friend to stay at our house for a few days. His name was Tobías, and he was dealing with some complicated paperwork, so he needed a place to sleep in the meantime. I’d known him forever, or so I thought. What I hadn’t wanted to admit was the way he’d been looking at me for a while.

It was a different kind of look. A half-smile and eyes that took all of me in without the slightest pretense, as if he knew something I still didn’t dare know about myself. I pretended not to notice. I’d walk down the hallway in my house clothes and feel his attention go straight to my ass, to my tits outlined under my braless T-shirt, lingering longer than was decent.

It’s nothing, I told myself. He’s my brother’s friend. Absolutely nothing is going on.

But something was going on. And that night in particular, the heat made everything impossible to deny.

***

The air conditioner had broken two days earlier and the whole house was like an oven. It smelled like summer trapped indoors, like sweat and something else I wasn’t brave enough to name. My brother fell asleep early after a couple of beers in front of the TV, and I stayed tossing and turning in bed, unable to get a single minute of sleep. The sheet stuck to my skin. Every minute dragged on forever. More than once that week I’d slipped a hand between my legs thinking about him, rubbing my swollen clit until I came biting the pillow, and even so, the next day I’d run into him in the hallway and get wet all over again as if nothing had happened.

In the end I gave up. I got up, tied my hair into a loose bun, and went up to the rooftop looking for a little air. Up there, at least, there was a warm breeze, and the city looked calm, with scattered lights and a silence that felt strange for that hour. I leaned on the railing and took a deep breath, trying to sort out everything I was feeling.

Then I heard footsteps. Heavy, slow, coming up the cement stairs. I didn’t need to turn around to know it was him. I knew it in my body before I knew it in my head, by the way the skin on my arms prickled and by how, without him touching me yet, I was already feeling my cunt throb beneath the thin fabric of my shorts.

Tobías appeared in the doorway without a shirt, wearing sports shorts and his chest still shining from the heat. He stopped for a second, looking at me from the frame, and then he spoke in a rougher voice than usual.

—Can’t sleep? —he asked.

I turned slowly, my back against the railing, and looked him straight in the eyes. I didn’t look away the way I usually did. That night, for some reason, I decided to hold his gaze. And I dropped my eyes on purpose, for one second, to the bulge clearly visible under his athletic shorts. When I looked back up, he already knew I’d seen it.

—It’s the heat —I said—. And other things.

I saw his jaw tighten. He took two slow steps closer, as if giving me time to run. I didn’t run. I stayed there, my heart in my throat and a current running down my belly to burrow between my legs, soaking my panties all at once.

***

I couldn’t say who moved first. Suddenly he was inches away, his heat mixing with mine, his breathing brushing my forehead. He put a hand on my waist, barely, like a question. I answered by leaning toward him and grabbing him right over his shorts. He was rock hard. A low groan escaped him when I squeezed his cock with my open palm.

—I’ve been imagining this moment for a long time —he murmured against my ear—. Every fucking night, you know? Every night I jerk off thinking about the way you move around the house, about your tits when you come down to the kitchen without a bra, about what I’d do to you if you let me.

I felt his mouth on my neck, soft at first, then hungrier. He sucked on my skin until I moaned, bit the curve of my shoulder, moved up to my ear and licked it slowly, and every kiss pulled a sigh from me that I no longer bothered to hide. His hands slid up my back, yanked my T-shirt off in one motion, and came back down. He grabbed my tits with both hands, not gently, pressing them into his palms and pinching my nipples until they went hard as stones. He tore a moan from me that echoed into the rooftop silence.

—Hush, baby —he whispered, smiling against my mouth—. You’re going to wake your brother.

He turned me carefully and pressed me against him. I felt how turned on he was through the thin fabric of his shorts, his hard cock digging into the small of my back, rigid and pulsing like it had a life of its own. He held me firmly, one hand on my hip and the other sliding up my stomach to close around a breast again, and I tipped my head back, resting it on his shoulder, rubbing my ass against his cock in slow circles.

The other hand went lower. He shoved his fingers under my shorts and panties in one tug, and when he found how soaked I was he let out a rough laugh against my ear.

—Look at you. You’re leaking, slut.

He spread my lips with two fingers and rubbed my clit in circles exactly the way I needed, while his other hand kept squeezing my breast. I arched against him, opening my legs wider, offering it all to him.

—Tell me to stop —he said, voice broken, sinking two fingers all the way into my pussy in one thrust—. Say it and I’ll stop right now.

—I don’t want you to stop. Don’t stop, please, don’t stop.

That was all he needed to hear.

He turned me again and finally kissed me on the mouth, a long, deep kiss, tongue seeking mine while his fingers kept moving inside me, in and out, getting completely soaked. I dug my nails into his back, pulled him closer, feeling how my whole body wanted more than my mind dared ask for. Every time he curled his fingers he hit a spot that sent stars flashing in my vision, and his thumb kept circling my clit until I thought my knees were going to give out.

—I’m going to come —I panted against his mouth—. Like this, like this, don’t stop…

—Come for me —he told me, speeding up his wrist—. Let me feel it in my hand.

I came right there, clenching around his fingers in long spasms, biting his shoulder so I wouldn’t scream. He didn’t stop until my thighs were trembling and I begged him to ease up. He pulled his soaked fingers out, brought them to his mouth without taking his eyes off me, and sucked them one by one.

—Delicious —he murmured—. Now it’s your turn.

I ran my hands over his chest, over his firm stomach, down to the waistband of his shorts. I looked at him one last time, searching for confirmation in his eyes, and I yanked down his shorts and boxer briefs together. His cock sprang out, hard, thick, the tip already shining with fluid, and seeing it like that finished setting me on fire. It was bigger than I’d imagined during all those nights locked in my room touching myself while thinking about him.

I knelt on the still-warm rooftop floor. I didn’t care about anything: not the cement under my knees, not the risk, not what we were doing. I took him in my hand, squeezed him at the base, and gave him a long lick from his balls to the tip. He shuddered all over and let out a low curse. I licked his head in circles, savoring the salty taste of the fluid beading there, and then I took him all the way into my mouth until the tip hit the back of my throat.

—Fuck —he moaned, burying his fingers in my hair without forcing it—. Like that. Just like that, suck my dick like that.

I took my time. I worked my mouth up and down with rhythm, tightening my lips around him, helping with my hand at the base to follow every movement. I used my other hand on his balls, stroking them gently, and he had to brace himself against the railing because his legs were weakening. I pulled off him for a second to lick him all over the side, to suck the head like it was candy, to spit on him and take him back into my mouth until my eyes filled with tears.

—Look at me —I asked, taking him out for a moment and jerking him against my open mouth—. Look at me sucking your dick.

I looked up from below and saw on his face a mix of pleasure and disbelief, as if he couldn’t believe this was happening either. He moved his hips, started fucking my mouth slowly, gripping my hair with both hands, and I let him, relaxing my throat and letting him sink in as far as he wanted. Saliva dripped down my chin, down my tits, and I didn’t give a damn.

When he felt he was about to come, he pulled out of my mouth almost violently and lifted me by the arms with a tenderness I hadn’t expected. He kissed me again, this time slower, tasting himself on my lips, and led me to the side wall of the rooftop, the one that faced the darkness of the courtyard.

***

He stripped off what little clothing I had left with a patience that drove me crazy, one piece at a time, pausing to kiss every inch he uncovered. When I was finally naked against the still-warm wall, his hands explored all of me, and his mouth followed the same path. He sucked my nipples one by one, barely biting them, slid down my stomach, and knelt in front of me.

He lifted one leg over his shoulder and buried his face between my thighs without warning. His tongue slammed into my pussy, long and broad, licking me from bottom to top, sucking my lips, penetrating me whole. I grabbed his hair with both hands and started moving against his mouth, unable to control myself, while he licked me like he’d had years of delayed thirst.

—You’re delicious —he moaned against me, and the vibration ran up my whole spine—. You’re all wet for me.

He pushed two fingers into me again while he sucked my clit, moving them fast, searching for that spot inside that made me lose my mind. I was about to come again when he stopped, stood up, and wiped his mouth with the back of his hand.

—Don’t you dare finish yet —he told me—. You’re going to finish with my cock inside you.

—I’m going to make you forget the world exists —he said, and it wasn’t a threat, it was a promise.

He held up one leg, settled against me, and drove his cock in slowly, looking me in the eyes the whole time. I felt how he opened me, how he filled me centimeter by centimeter, how my cunt throbbed tight around him, adjusting to the thickness, and I let out a cry I had to smother against his shoulder so I wouldn’t wake half the house.

—So tight, you slut —he panted against my ear—. You were made for my cock.

He started moving in rhythm, not rushing at first, pulling almost all the way out and then driving back in to the hilt, holding me firmly against the wall. Every thrust tore a new moan from me, deeper than the one before. I dug my heels into his lower back, pulled him in, asked for more without words, only with my body. And he sped up. He started fucking me harder, slamming into me in a way that made the wet sound of our bodies colliding audible in the rooftop silence.

—Don’t be quiet —he said in my ear—. I want to hear you. Tell me how I’m fucking you.

—You’re fucking me so good —I moaned, barely recognizing my own voice—. Fuck me, don’t stop, like that, harder…

And I didn’t stay quiet. I let out everything I’d been holding in for months, all the repressed desire from the hallways and the pretending glances. He answered every sound I made by speeding up, sinking deeper, kissing my mouth, my neck, my shoulders, biting my nipples without stopping his thrusts.

He pulled me away from the wall, turned me around, and made me put my hands on the railing. He spread my legs with a little kick and shoved into me from behind in one hard thrust, gripping my hips with both hands. I lowered my head, arched my back, and offered him my ass whole so he could do whatever he wanted.

—This is how I wanted you —he growled, smacking my ass hard enough to make me jump—. On all fours. Like a bitch.

He drove into me again and again, faster and faster, deeper and deeper each time. I stared at the city lights below while my brother’s friend wrecked my pussy against the railing, and I couldn’t believe how good it felt. He grabbed my hair, tugged gently, and bent me back a little so he could kiss me sideways on the mouth without stopping his thrusts.

***

At some point he lowered me to the ground, onto an old towel that had been left hanging on the railing, and we kept seeking each other there, between the breeze and the city lights. I got on top of him, sank his cock into me slowly, sat down until he hit bottom, and set my own rhythm, bracing my hands on his chest while he held my hips and looked at me with an intensity that undid me.

I rode his cock the way I’d wanted to for months, going all the way up and down, then moving in circles, squeezing him inside me every time I reached the bottom. He watched my tits bounce and licked his lips. He took my hands to my breasts, made me squeeze them myself, and then asked me to put my fingers in my mouth and suck them. I did everything he said. I felt like a slut and I loved it.

—You’re going to drive me crazy —he panted, slapping my ass every time I dropped onto him—. You have no idea. Move, like that, move that ass for me.

He sat up suddenly, ending up with me on top of him, and grabbed my waist to thrust up into me while he bit my nipples. I wrapped my arms around his head, pressing them against my face, and felt everything gathering at the center of my body, a wave growing and growing until I couldn’t hold it back anymore.

—I’m going to come —I moaned in his ear, moving faster and faster—. I’m going, I’m going…

—Come on top of me —he growled—. Soak my cock.

I leaned forward, kissed him, and let him take me there. The orgasm shook me from head to toe, and my legs trembled in a way I’d never felt before. My pussy closed around him in waves, squeezing him so hard he let out a long curse against my neck.

He pulled me off him in a hurry, laid me on my back on the towel, and knelt between my legs, jerking himself off quickly with one hand over my stomach.

—Where? —he panted—. Tell me where.

—On my tits —I begged, grabbing them and pressing them together for him—. Come on my tits.

It took only a few more seconds. He came with a rough groan, and I felt the hot spurts falling over my breasts, over my neck, one even reaching my chin. He stayed there, breathing hard, looking at me drenched in his cum, and then he leaned down to kiss me without caring about anything.

We stayed like that for a long while, breathless, stuck together by sweat and by what he’d left on me. All you could hear was our breathing and, far off, some dog barking.

***

We went back down almost half an hour later, in silence, each of us separately so we wouldn’t make noise. I got into the shower with my legs still weak and my whole body buzzing, trying to understand what had just happened and why I didn’t feel even a speck of guilt. Under the hot water I ran my fingers between my legs and my clit was still trembling with sensitivity.

Tobías went to sleep in the guest room as if nothing had happened. But the next morning, at breakfast, when my brother was telling some story without noticing anything, he and I exchanged a look over our coffee cups. A look that said everything.

Since that night, every time he comes over we know exactly how it’s going to end. On the rooftop, in the kitchen when everyone’s asleep with my ass on the counter while he’s fucking me with his hand over my mouth, in the bathroom with the shower running so no one can hear my moans, in any corner where nobody can see us. We plan it with glances, with little accidental brushes as we pass each other, with that kind of complicity that only exists between two people who share a secret.

My brother still doesn’t know that his best friend fucks his sister whenever he can. And even though I know that someday I’ll have to decide what to do with this story, for now I’d rather stay quiet.

Because the truth, and this is my most honest confession, is that I don’t plan to stop.
