My First Anal Experience After the Gym

I'm going to tell this because it still surprises me to remember how much that afternoon changed the way I enjoyed sex. Until then, I thought I knew my body, my limits, and my desires well. I was wrong. My boyfriend, Mateo, already knew how to turn me on, but that day he found a door I myself had kept closed out of fear, shame, and sheer ignorance.

We were both adults, past thirty, with an intense and very physical relationship. We saw each other almost every day, and whenever we were alone, it was hard for us not to end up naked somewhere in the house. I had always been horny with him, one of those women who don't need to pretend when they're touched properly. Mateo was patient when it came to arousing me, and shameless enough to whisper dirty things in my ear until he made me lose my composure.

My body had always attracted attention because of my hips and my ass. I don't say that to brag; at first, it embarrassed me terribly. I could put on a long T-shirt, walk quickly, and look straight ahead, but I still felt people's eyes fixed on me whenever I crossed the street or entered a place. Mateo noticed it from the beginning. At first, he would get serious whenever some man kept staring. Then he started getting turned on by it.

That change in him confused me. He would take my hand more firmly, press me against his body, and then, when we were alone, tell me that he loved seeing other men make fools of themselves over my ass, knowing that he was the one who had me in bed. I laughed, but inside, the idea started to turn me on. It made me feel watched, desired, and, at the same time, protected by the brazen possessiveness he displayed.

That Saturday we went to the gym in the middle of the afternoon. It was hot, and I was wearing very tight athletic shorts, a simple top, and a large T-shirt over them. Before we left home, Mateo looked me up and down and asked me to take off my T-shirt. I told him no, that it showed everything. He came closer, grabbed me by the waist, and kissed me slowly.

—I want to see you work out like that —he said against my mouth—. I want everyone to look at what I'm going to touch afterward.

I felt a wave of heat in my chest. I was embarrassed, but hearing that sentence also made me wet. In the end I left wearing the clinging shorts and the top, pretending to be confident while every step made me aware of my ass moving beneath the fabric. On the way, several men stared without even trying to hide it. I lowered my eyes, but Mateo smiled with a calmness that made me nervous.

At the gym we split up to do our routines. I had legs and glutes that day, exactly the worst thing if I wanted to go unnoticed. Every squat made me feel the shorts stretching against my skin, and whenever I bent over to pick up a dumbbell, I noticed eyes around me. Mateo was working out a few yards away, but every so often he stopped to watch me. He said nothing. He only looked at me as if he were already imagining what he was going to do to me.

When he finished his set, he came over to leave a towel beside me. He brushed my back with his fingers and leaned in to speak into my ear.

—Dressed like that, I'm going to take care of you when we leave.

I laughed nervously, but the laugh came out weak. My thighs were tired, my skin was hot from exercising, and an uncomfortable dampness was growing between my legs. It wasn't just sweat. The way Mateo looked at me, the idea that other people were looking at me too, and the fear of being discovered had me more aroused than I wanted to admit.

We finished our routine and went down to the underground parking garage. The elevator was empty. As soon as the doors closed, Mateo pressed me against the metal wall and kissed me with an intensity that stole my breath. His hands went straight to my buttocks, squeezing them over my shorts, and he gave me a sharp slap that made me let out a moan.

—Not here —I murmured, looking at the floor indicator.

—Then hold out until we get to the car —he replied, squeezing my ass harder.

We got out trying to walk normally, but I was already trembling. The parking garage was almost empty, with yellow lights and concrete columns that left areas of shadow. Mateo opened the car door, let me get in, and sat behind the wheel. For a few seconds he didn't start the engine. He just kept looking at me, breathing heavily.

—I can't stand seeing you like this —he said—. Come here and suck my cock.

I leaned toward him without thinking too much. I pulled down his athletic shorts and took out his cock, hard and hot, with that familiar ease that always lit me up. I took it in my hand and ran my tongue over the tip slowly, tasting the salty flavor already on it. Mateo let his head fall back against the seat and tangled his fingers in my hair.

—Take off your top —he ordered—. I want to see your tits while you suck me.

I took it off as best I could inside the car. My tits were free, heavy with the heat, my nipples hard from arousal and the cold air of the garage. He pinched them, gently at first and then harder, until I moaned with his cock in my mouth. I liked feeling so exposed, half-hidden behind the dark windows and, at the same time, knowing that all it would take was a distracted security guard to ruin everything.

I sucked him eagerly. I moved my mouth up and down his cock, wetting it with saliva, taking it as far as I could without choking. When I focused on the head, he clenched his teeth and told me dirty things that made me soak my shorts even more. I ran my tongue underneath it, over the vein that drove him crazy, and then masturbated him while licking the tip with quick movements.

—That's it, my love —he growled—. What a delicious mouth you have.

I wanted to keep going, but the heat inside the car became unbearable. I looked toward the windshield, afraid of seeing someone walk by. Mateo grabbed me by the nape and pulled me up to kiss me, tasting himself in my mouth. Then he pointed toward the back seats.

—Get in the back.

I obeyed, my legs weak. I moved awkwardly between the seats, my top lying on the floor and my tits bare. Mateo reclined the front seats to make more room and climbed in behind me. As soon as he arrived, he laid me on my back and latched onto my breasts. He sucked my nipples hungrily, lightly bit them, let them go to look at them, and then went back to devouring them as if he couldn't decide on just one.

His hand moved down between my legs. At first he touched me over my shorts, rubbing the fabric against my cunt. The Lycra was soaked, clinging to my lips, and every pressure of his fingers drew a louder moan from me. I told him to lower his voice, that they might hear us, but he covered my mouth with his hand and moved his fingers more boldly.

—You love letting them hear you —he said—. You're dripping.

I couldn't deny it. My body was responding on its own. I spread my legs wider and began moving my hips against his hand, seeking more pressure. He rubbed my clitoris through the wet fabric in firm circles while I licked the palm that was still covering part of my mouth. Shame mixed with brutal arousal. I felt dirty in the best possible way, trapped in the back seat, naked from the waist up, with my boyfriend touching me as if the outside world didn't exist.

—Don't take off your shorts —he suddenly said—. Turn around.

I got on all fours on the seat, bracing my hands against the backrest and sticking my ass out toward him. I felt Mateo go still for a second as he looked at me. Then he grabbed my buttocks and spread them over the Lycra, breathing heavily. The fabric was wedged between my lips and outlined every curve. He pulled one side of the shorts so hard that the seam gave a little, enough to move them aside and expose my cunt.

He pushed two fingers inside without any further warning. I was so wet that they slipped in easily, all the way, and I moaned against the seat. He opened me with slow movements, sliding his fingers in and out while squeezing one cheek with his other hand. I pushed backward, asking him with my body not to stop. The wet sound of his fingers entering my cunt filled the car.

—I want your cock —I told him, my voice broken—. Fuck me now.

But Mateo didn't listen. He took his fingers out of my cunt, ran them through my slit, and began moving upward toward my ass. I tensed immediately.

—What are you doing?

—Just one finger —he replied in a low voice—. Let me feel you there.

I'd never done it before. I was afraid of the pain, the strange sensation, of losing control. But I was so aroused that I didn't want to stop him. I lowered one hand to my clitoris and began touching myself while he wet my asshole with my own fluids. The first pressure felt strange and closed off, as if my body were reflexively saying no. Then I took a deep breath, clenched my teeth, and let him continue.

—Slower —I asked.

Mateo pushed carefully but insistently until the fingertip entered. I let out a whimper that was neither pure pain nor pure pleasure, but surprise. The sensation was unlike anything else. It filled me in a forbidden, intimate, excessively direct way. He inserted his finger little by little, barely rotating it, and I rubbed my clitoris faster to help my body open.

—That's it, little bitch —he said—. Stick your ass out farther for me.

That phrase aroused me. I arched my back, opened my legs wider, and pushed backward. The finger went all the way in. Mateo began moving it slowly, in and out, while his other hand touched my open cunt. I was so wet that I soaked his fingers. The contrast drove me crazy: my clitoris beneath my hand, his finger in my ass, his dirty words pressed against my ear.

Then he added another finger. That was when I felt strong pressure, a stretching that made me bite the backrest so I wouldn't scream. He didn't stop completely, but slowed down, letting my body give way. When both fingers were inside me, I began moving myself against them. It wasn't only fear anymore. It was desire. A dark, new desire that burned from my belly down through my legs.

—Do you want me to fuck your ass? —he asked.

My face was against the seat, my tits flattened, and my fingers were soaked from touching myself. I was embarrassed to say it, but I did.

—Yes. I want you to fuck my ass.

Mateo pulled out his fingers and positioned himself behind me. I felt his cock sliding between my buttocks, hard and wet with saliva and my fluids. He rubbed the head against my open asshole without entering yet, making me tremble every time he pressed. I spread my own cheeks with my hands to give him a better entrance.

—Look at me opening myself for you —I murmured, surprised to hear myself sounding so obscene.

He pushed slowly. The tip entered just a little, and my body closed around him. It burned. Not unbearably, but intensely, fully, animalistically. I stayed still, breathing quickly, while he held my hips. Then he advanced a little farther. I felt him stretching me, felt my ass adapting inch by inch, and a long moan escaped my throat.

—You're so tight —Mateo said—. You're going to drive me crazy.

When he was halfway in, I began touching my clitoris again. That changed everything. The pain mixed with pleasure, pleasure with pressure, and suddenly I wanted more. I pushed backward, silently asking him to finish sliding it inside me. Mateo obeyed. He entered all the way with a slow, firm movement, and I screamed into the seat.

He stayed still for a few seconds, completely buried in my ass. I could feel every pulse of his cock inside me, a hot, deep presence that left me breathless. Then he began to move. At first slowly, sliding in and out carefully, listening to my moans and watching my body get used to him. Then, when he heard me say “more,” he lost patience.

He gripped my hips tightly and began fucking my ass with longer thrusts. The car moved slightly. My knees slipped on the seat, my tits struck the backrest, and my hand never stopped rubbing my clitoris. Every time his cock entered, I felt a deep shock travel up my spine. It was too much, and even so I wanted him not to stop.

—That's it, love, that's it —I moaned—. Don't stop.

Mateo slapped my buttock hard, and the blow made my ass tighten around him. I heard him curse under his breath. He bent me farther forward, almost crushing me against the seat, and changed the angle. Then the sensation became more intense. Every thrust pushed me toward my own hand, and my swollen, sensitive clitoris responded with rapid jolts.

I no longer thought about the parking garage, the guards, or the shame. There was only his cock entering my ass, my wet cunt, my body opened in a way I had never allowed. I came like that, with a sharp convulsion, gritting my teeth and trembling from my legs upward. The orgasm took me by surprise, stronger than I expected, and I had to cover my mouth so I wouldn't scream too loudly.

—I'm coming —I babbled—. Keep going, keep going.

He kept going. He fucked me faster while my ass throbbed around his cock. I was still in the middle of my orgasm when I felt his rhythm become uneven. He held me with both hands, digging his fingers into my waist, and thrust all the way in once, twice, three times. Then he stayed pressed against me, growling my name, his body tense and his breathing ragged.

We stayed like that for a few seconds, sweaty and silent, trying to return to the world. When he pulled out of me, I felt a strange emptiness and a sensitivity that made me close my eyes. Mateo helped me sit up and kissed me with a tenderness that contrasted with everything we'd just done. My hair was disheveled, my shorts were torn, my tits were exposed, and I wore a stupid smile I couldn't wipe away.

—Are you all right? —he asked, stroking my cheek.

—I'm better than all right —I replied, still breathing heavily.

I got dressed as best I could before anyone passed near the car. The long T-shirt covered me again, although inside I could still feel every inch of what had happened. We left the parking garage without saying much. Mateo drove with one hand on the wheel and the other resting on my thigh. I looked out the window, red with embarrassment and satisfied desire.

That was my first time anal. It wasn't perfect, planned, or clean like those orderly fantasies one imagines when one thinks too much. It was hot, clumsy, intense, and deeply ours. From then on, I understood that some doors of the body open only when desire outweighs fear. And that afternoon, in the back seat of a car, I let Mateo open one that I never completely closed again.
