I Stripped for Him Without Him Knowing They Were Watching Us

Almost two weeks passed after that afternoon I told you about in the previous story. By then I had already met Camila in person, and the connection between us had grown faster than I expected. We went out alone a couple of times, talked for hours, and, between laughter and red wine, ended up sharing more than one long kiss at the table of some neighborhood bar.

Camila had this habit of proposing games. Little challenges we threw at each other to push our limits bit by bit, a key that opened doors neither of us dared to touch alone. That week she threw me hers: she wanted me to show my body to Sebastián, the guy at the gym who had been dropping hints at me for months. From the way he looked at me whenever we crossed paths in the weights area, you didn’t need to be especially sharp to know he was into me.

—This is the perfect opportunity —Camila told me—. You tell the story afterward, you write it, and, above all, you enjoy it. Because you like feeling that other people’s gaze on you more and more, don’t you? Or are you going to deny it to me?

I didn’t deny it. I told her I accepted the challenge.

A few days earlier I had mentioned to Sebastián that I’d be away for the weekend. Mateo and I had that Friday off and had promised ourselves two nights by the sea, at a quiet little hotel on the coast. Camila couldn’t come, so it would just be the two of us. What mattered for the challenge was the excuse. I asked Sebastián to help me choose a couple of swimsuits. I framed it as a joke between friends, but his eyes lit up. We agreed to stop by a shop when we left the gym the next day.

When we were standing in front of the counter, we took out several styles. The idea was that I’d buy two: one with a thong cut, daring for the first afternoon, and another, more discreet bikini, in case the mood changed on the second day. He always leaned toward the smallest ones and I chose the conservative ones. I went into the fitting room with the two finalists and, after paying, asked him to take me home.

—I’ll buy you a protein shake —I told him—. I know you’re out of yours.

He didn’t think twice.

We arrived at an empty apartment. Mateo was at Camila’s place; I knew because she had texted me half an hour earlier. It was exactly the moment I had planned. I propped the phone behind a thick book on the living room shelf, at an angle that covered the whole room, and started a video call with Camila. She answered on the first ring. Sebastián didn’t notice a thing. I asked him to prepare the two glasses in the kitchen while I went upstairs to try on the thong.

I stripped quickly in my room, my heart racing. I tied the bra strings around my neck and adjusted the red thong in front of the mirror. It wasn’t a string: it was something in between, smooth fabric that left most of my ass exposed but covered just enough in front. The top was two small cups held up by thin straps. I liked what I saw in the reflection. It wasn’t vulgar, it was sexy, and I knew right away it would be my favorite for the first beach afternoon.

Here we go, I thought, and went downstairs with the other swimsuit in my hand and a tight knot in my stomach.

Sebastián was waiting at the bottom of the stairs with both glasses raised. When he saw me appear, he visibly jolted. His eyes opened wide, he swallowed, and let out a line that was part admiration, part cheek.

—It fits you perfectly. You’ve lost weight, it looks gorgeous on you. This is definitely the one you have to wear.

I turned slowly. Not just so he could appreciate it: mostly so Camila and Mateo could see me clearly from the hidden phone. I felt his gaze glued to my legs, to the low curve of my back, to the soft marks the fabric left on my hips. I managed to make out the bulge beginning to show in his tracksuit pants, that thick swelling pushing forward that he was trying to hide by positioning the glass at crotch level.

—Too bad I can’t fit myself in your suitcase and go with you —he joked.

We laughed. Then he lowered his voice, as if he were about to give me serious advice.

—Just one thing: if you don’t want to show too much, you’ll have to be careful. Your nipples show through.

I looked down. It was true. The thin fabric clung to me and there was no way to hide it. I shrugged.

—It’s cold in here. It’ll be hot on the beach, you won’t notice.

—But I know you —he said, almost in a whisper—. And they’re hard.

—Well, you’re not going to tell anyone, are you?

I laughed, feeling the heat rise in my ears. He shook his head, promising discretion with a smile that said the exact opposite. Then he tossed out another joke to break the tension and asked me to try on the other style.

***

He was at the edge of the kitchen and I was in the living room. Barely three meters separated us. My bedroom was upstairs, so I decided to try it on right there.

—I’ll change here so I don’t have to go back upstairs.

—Whatever you want, it’s your house.

Sebastián came closer with the glasses in hand and sat on the sofa, right in front of me. I turned my back to him at first, as a fake gesture of modesty, and took off the bra. Then I let the thong fall to the floor, dragging it slowly down my thighs until it lay there like a little red puddle on the carpet. I turned to him completely naked, holding his gaze for a second longer than necessary. The room filled with a thick silence. I felt his eyes travel all over me, without even pretending, swallowing hard every time they dropped from my tits to the dark triangle between my legs. I knew that on the other side of the phone Camila was holding her breath, and probably already had her hand between Mateo’s thighs.

—I always thought you’d be completely shaved —he said, with a crooked smile, unable to tear his eyes off my cunt.

I burst out laughing and shook my head. I opened my legs a little, just enough for him to see how the hair parted in two and let the pink lips show through, already a little shiny with moisture.

—I like my hair. It has its charm. And some people like how the tongue sticks to it, you know?

A low, almost rough gasp slipped from him. I watched his cock swell against the fabric of his pants, a thick, well-defined bulge, the tip pushing upward. He shifted on the sofa, squeezing his thighs together, and his cock moved on its own under his clothes.

—I prefer it clean —he managed to say—. But it’s your body, you make the rules. And with that view, you can make whatever rules you want.

While he kept talking, I accidentally pinched one nipple between two fingers, as if adjusting it, and he bit his lower lip. Then I slid the black bikini bottoms down my legs and pulled them up slowly, giving him time to take it all in: the thighs, the curve of my ass when I bent over, the nipples hanging when I leaned forward. I stood up, adjusted the fabric on my hips, and put on the top. When I faced him again, he locked his gaze back on my chest.

—You were right about the cold —he said—. They’re hard again.

—Don’t tell me, I already know.

I adjusted my bra and the two of us gave our verdict: the red one won for the first afternoon. The black bikini would be for the second. Case closed.

—I’m going upstairs to change. Can you bring my glass up?

He nodded and followed behind me upstairs. I felt his eyes on my ass the whole way, like a hot hand that never quite managed to touch me. I swayed my hips a little extra, knowing that with every step his cock was shifting under his pants. We went into the room and, without any further preamble, I took everything off. I ended up naked in front of him once more, standing still, waiting for him to react. He remained there with the glass extended, but his other hand went on its own to the bulge and adjusted it up and down, as if it were heavy. I took the glass with both hands and started drinking. The shake was ice cold and I felt my skin rise in goosebumps all over. My nipples hardened even more, turned long and red, pointing at him like two stiff fingers.

—You have very pretty nipples —he said, not looking away—. I’d be watering at the mouth sucking on them.

—Shut up —I answered, playing along, but without covering myself.

I held his gaze while I ran a cube of cold milk over one nipple until it got so hard it started to hurt. Then I brought my finger to my mouth and sucked it slowly, tasting it. He blew out air through his nose, almost a snort. I saw him press his cock with his palm, barely bothering to hide it. It was hard, thick, curved upward inside his pants, so tense that even the head was outlined against the fabric.

—You’re killing me —he murmured.

—Hold on a little. You’re not dying yet.

I left the glass half-finished and covered myself with a black blouse, no bra. The thin fabric clung to my body and left the tips outlined, two dark bumps that said everything. I put on a comfortable pair of panties and soft lounge pants. Sebastián ran his eyes over me again, this time more slowly.

—It would be nice if some friend came on the trip —I teased him while I finished the shake—. If Mateo gets bored of me, at least I’d have someone to drink a beer with on the shore.

He got the hint right away.

—If you want, I’ll pay my own way and go. Hotel separate, all out of my own pocket. I just need you to let Mateo know and that’s it.

—I’ll think about it. Mateo’s easygoing, it won’t bother him.

We left the room and, while I walked him to the door, he repeated the offer. I assured him I’d mention it to my boyfriend, even though I knew perfectly well Mateo was hearing every word through the hidden phone in the living room.

***

When we got to the street, Sebastián stopped before getting into the car.

—Why did you do that? —he asked me, not accusing, but not hiding it either.

—It’s nothing bad —I replied, shrugging—. I trust you, I consider you a friend. Nothing happens between friends.

—So I shouldn’t read anything into it?

—No. I just wanted you to trust me too. That’s all.

He seemed calmer. He leaned in to give me a quick kiss on the cheek and, just at that instant, I felt him gently squeeze one nipple through the blouse with two fingers. Then he lowered his hand and brushed the other one, pinching it just enough to draw a gasp from me I couldn’t quite hide.

—Why do men always do the same thing? —I blurted out, laughing almost against my will, with my legs pressed tight together.

—I wasn’t going to leave empty-handed. And if it helps, I’m going home with a rock-hard cock. I’m going to have to jerk off as soon as I get home, thinking about you.

—Then think carefully. And don’t forget a single detail.

He got into the car and drove off. I went back into the house breathing hard, shoved the door shut, and ran to get the phone. The camera was still on. Camila and Mateo were definitely not being quiet. The screen showed them on the bed, her on top of him, tits out and her mane falling over her face. Mateo was holding her by the hips and guiding her slowly, with that same slow, sure confidence he uses when he fucks me and there are no witnesses. You could see his cock going in and out of Camila’s cunt, wet, shiny, with my friend’s lips stretched around the shaft every time she sank all the way down.

—Oh, you feel so good —Camila moaned, pressing her tits against his chest—. You fill me up, Mateo, you fill me completely.

—Ride me harder —he growled, slapping one ass cheek—. Like that, riding me like a bitch.

Camila obeyed. She leaned forward, bracing her hands on his chest, and started moving up and down with more fury. Her tits bounced, her ass slapped against Mateo’s thighs, and every thrust made a wet sound that came through the speaker crystal clear. He dug his fingers into her hips and drove her down, spearing her to the hilt. You could see Camila’s wet pussy glisten each time she rose, Mateo’s cock sliding out almost all the way before plunging back into her.

I ran upstairs with the phone clenched in my hand, already soaking my panties. I threw myself onto the bed, yanked off the lounge pants and underwear in one pull, spread my legs and brought two fingers to my cunt. I was so wet they slid in on their own. I rubbed my clit in circles, pressing hard, watching Camila come on Mateo, with those sharp little moans she makes when she can’t take it anymore.

—Oh, I’m coming, I’m coming, I’m coming —she squealed on the screen, arched, with her nipples standing up.

I shoved two fingers inside and started pumping myself at the same rhythm she was riding my boyfriend. I imagined Sebastián’s cock, how hard it would have been under his pants, how he would have put it in if I’d gone one step further. I imagined his hands squeezing my tits, his mouth sucking my cold nipples, his cock entering me from behind while I licked Camila’s tits. I pushed in a third finger, thrusting hard, feeling my cunt tighten around them and the liquid slip down my thighs onto the sheets.

On the screen, Mateo grabbed Camila by the hair and flipped her onto her back. He got on top of her, spread her legs wide and drove into her with one brutal thrust. Camila let out a deep cry. He started fucking her at a savage pace, hammering her pussy with every shove, his balls slapping her ass, the bed creaking. I rubbed my clit faster, palm open, while with my other hand I pinched each nipple in turn. I could see Mateo’s taut back, his ass tightening every time he sank into Camila, and her nails dug into his shoulder blades.

—Put it all in me, fuck me, fuck me, don’t stop —Camila begged him, biting her lips—. Let her see you, let her see everything.

When she sped up, pushing her hips against his, Mateo let out a rough groan, buried himself all the way in and I knew he was coming inside my friend. His ass clenched, his thighs tensed, and she let out another long moan when she felt him fill her. I came almost at the same time, biting my arm so I wouldn’t scream, my legs shaking and my cunt spilling a warm stream over the sheets. I stayed there panting, with my fingers still inside, squeezing myself slowly to stretch out the last spasms.

And I was still tasting the afternoon in my mouth, I thought, with the pinched nipple still burning and Sebastián’s scent stuck in my memory.

When they were done, Camila brushed her hair back, smiling, her tits still flushed red and a thick thread of semen running down the inside of her thigh. She moved closer to the camera and pointed at me.

—Challenge accomplished, my love. And let me tell you, you’re good enough to eat. I came while watching you too, not just because of Mateo.

Mateo, still with a rough voice, came up to the phone. His cock was halfway soft, shiny, with white residue on the tip.

—We’ll see each other at the office tomorrow. And you’d better tell Sebastián yes, that he should come on the trip. I’ll take care of the rest. I like the idea of watching you while another guy puts it in you.

Camila gave him an affectionate elbow to the ribs, slid two fingers between her legs and brought them to her mouth, sucking them while keeping her eyes fixed on the camera.

—I wish I could go too. But since that’s not possible, make the most of it. I’m giving you permission to set up a threesome with the two of them —she said, laughing—. Or do I need to ask you in writing? I want photos, I want videos, I want you to tell me what it feels like to have both of them on you at the same time, one in front and one behind.

I let out a nervous laugh, still sticky between my legs. I ended the call, but the idea kept spinning in my head like a trapped fly: Sebastián with his cock out, Mateo watching me, both of their hands on me at the same time. I stroked the wet sheets, still feeling the weight of the afternoon on my body, the memory of those two invisible pairs of eyes, the discreet pinch at the door, and that thick bulge in Sebastián’s pants when he looked at me naked.

Maybe, with thirty-five about to hit, it was finally time for my first threesome.
