I Spied on My Girlfriend While She Initiated the Apprentice

Gonzalo and I had built a strange friendship, made up of favors that never quite got settled. I owed him money, quite a lot of it, and he collected in his own way: he came by my girlfriend almost every week, and Nadia, far from complaining, seemed more and more involved in the whole thing. I told myself it was because of the debts. I was only half lying, and we both knew it.

One afternoon he called me to the workshop with that smile of his, the smile of a man who already has everything decided.

—I’ve got an idea —he said—. I want to get Tomás into this.

Tomás was his helper. A big kid, slow to talk, painfully shy, who stumbled over his words and looked down when anyone greeted him. He was nineteen and, according to Gonzalo, had never been with a woman.

—Not a chance —I said—. Nadia isn’t merchandise.

—Nobody said she was. But the kid adores her. His eyes almost fall out every time he sees her come around here. And he’s never touched anyone. I want his first time to be with someone who’ll treat him well.

And that, of course, was his call.

—Find someone else.

—It’s not the same. Nadia has something. Besides, I’ll put up the money. You name the number.

I told him I’d talk to her, more to buy time than anything else. Gonzalo laughed.

—I already talked to her. She’s in.

—You’re quick.

—There’s a reason I have what I have. I don’t sleep, darling.

That night I talked it over with Nadia, convinced she’d side with me. I was wrong.

—He already told me —she said, without looking up from her phone—. Poor Tomás, I feel sorry for him.

—I don’t think it’s right. It’s different.

—Different from Gonzalo? Why? —She put the phone down and pinned me with her eyes—. You like it when he watches me. You like it when they fuck me and you watch them split my cunt open. Don’t come at me with morals now.

—It’s just that the kid is… innocent. He’s never fucked anyone.

—He’s nineteen. And he has every right to put his dick somewhere at least once in his life. —She leaned closer and lowered her voice—. Besides, don’t tell me you can’t imagine the scene. The poor virgin asshole sucking on my tits while you watch. Just thinking about it gets you hard. Your cock’s already standing at attention.

She put her hand between my legs and confirmed, with a smile, that I couldn’t deny anything. She squeezed the bulge over my jeans, feeling how it hardened in her palm, and ran her tongue along my earlobe.

—You son of a bitch —she murmured, delighted—. You’re already seeing it in your head. You’re already fucking it in your mind. Me fucking him and you fucking the scene.

I didn’t say anything else. I turned away with my face burning, and heard her laughing behind me.

***

I gave in, as I always gave in, but I set one condition: I was going to be there. We agreed to do it in the back room of Gonzalo’s place, on an old platform he’d added a mattress to, with a crooked floodlight aimed straight at the center. Everything else stayed in shadow. From there, sitting in a chair against the wall, I’d be able to see without being seen.

The next day, Nadia arrived dressed for the occasion. A short slip, her panties, bare feet, her hair loose, and soft makeup that lit up her face. She was beautiful, and that direct light on the platform made her look almost unreal.

When Tomás came in and saw her, his eyes lit up. He knew what was going to happen, and he trembled like a boy faced with a gift too big for him.

—Come here —she said, patting the mattress—. Get up here, easy.

He obeyed clumsily. Nadia hugged him, gave him a long kiss on the cheek, and spoke to him in a low voice while he answered in monosyllables, glancing at me sidelong as if he feared I’d throw him out with a shout.

—Don’t look over there —she said, turning his face with a finger—. Look at me. It’s only me. Today you’re going to be my little stud.

She stripped him until he was left in his underwear. She ran her hands over his chest, slowly, and asked him in his ear what he wanted to do.

—I don’t know —he said.

—Shy, are you? Say it softly. Want me to suck you off? Want to put your dick in my mouth? In my cunt? Tell me.

He murmured something I couldn’t make out, but I saw the bulge growing inside his underwear, taking shape in a way that even impressed me from my corner. Nadia smiled.

—You want me to do it then? Want me to guide you?

—Yes, yes, yes.

***

She raised her arms and let him pull her slip up. When her breasts came into view, Tomás stared at them with his mouth slightly open, his cheeks flushed. Nadia had firm tits, her nipples already hard, pointing up under the floodlight.

—You like my tits? —she asked, cupping them from below and offering them to him.

—A lot. A lot.

—Want to touch them? Go on, touch them. They’re yours for today.

He touched them only lightly, with his fingertips, as if afraid of breaking something. There was no doubt it was his first time. He looked like a kid with the toy he’d waited his whole life for. Nadia took his hands and pressed them herself against her breasts, forcing his fingers into her flesh, teaching him how to grope her without fear.

—Like this, harder. You won’t break me. Squeeze my nipples. Yes, like that. Now suck them for me.

From the darkness, I couldn’t stop watching. I was surprised by the way Nadia moved: all that sensuality put at the service of someone who barely understood what was happening to him. She stroked his nipples, pinched them gently, and every so often turned her head toward where I was, knowing the light showed her completely while erasing me. I already had my hand down between my legs, squeezing my cock over my pants, feeling it pulse with every one of her gestures.

—All right —she said in a playful voice I wasn’t expecting—. Now we’re going to give the baby his little tit, and then we’ll bathe him.

Tomás transformed at those words. She tucked him against her chest like a child, and he latched on with clumsy, desperate hunger that she had to stop with her hand until he calmed down. The boy closed his eyes. His whole face changed, softened into a calm I’d never seen before. He sucked avidly, tugging at the nipple, drooling over it, breathing hard.

How can he accept this, I thought. And why has she got me nailed to the chair with my cock out.

I’d lowered my zipper. I had it in my hand, hard, wet at the tip, and I was stroking it slowly so I wouldn’t come too fast.

—Let’s give the other one, so you don’t stay hungry —Nadia said, switching breasts.

He went harder on the other breast, nipping at the nipple, and she let out a moan halfway between pleasure and annoyance. She stroked the back of his neck while he kept suckling, and with her other hand she slid down his belly to the elastic of his underwear.

***

—My baby’s had his milk already —she said a while later, gently separating him from her, his nipple shining with saliva—. Now let’s change him.

She sat down on the floor and rested Tomás’s head in her lap. She pulled his underwear down, and all at once a thick, long cock was visible, already awake, pointing at the ceiling. I saw Nadia’s face change. She looked at him in surprise, then toward my corner with a look of astonishment that needed no words. The kid’s dick was almost twice the size of mine, thick as a doll’s arm, veins standing out and his balls swollen beneath it.

Nature is strange, I thought. What it didn’t give on one side, it gave on the other.

—I didn’t imagine it like this —she said, almost to herself, wrapping her hand around it and realizing she couldn’t even close her fingers around it—. Look at the size of this thing. You’re an animal, Tomás.

She started jerking him off slowly, sliding her fist up and down, watching the tip turn purple. She squeezed his balls with her other hand, weighing them, and heard him moan for the first time.

She laid him back on the mattress and, without holding back, started kissing him. She worked her way down his chest, his stomach, until she reached that huge dick. She took it in both hands and ran her tongue from his balls to the tip, one slow lick that left a trail of saliva shining under the light. Then she took it into her mouth. At first only the head, sucking hard, cheeks hollowed. Then she went farther and farther down, helping herself with her hand on what wouldn’t fit, until I could hear her moaning around the boy’s flesh. She was choking on it, pulling the cock out all slobbery, spitting on it, and taking it back in until it hit the back of her throat.

I watched her give herself over with an eagerness that had little to do with the favor she was supposedly doing me. That mouth, those shining eyes, the way she sucked him off while glancing at me sidelong, were not the mouth, eyes, or gestures of someone fulfilling an obligation. She sucked each ball one by one, dragged them over her lips, and went back to the cock hungrier than before. I was jerking myself in the chair, hypnotized, my pants down around my thighs.

The boy, who had never felt anything like it, lasted only a few more seconds. He started shaking all over, his legs tensing, and he emptied her mouth with one hard pull. Nadia didn’t manage to swallow it all: part spilled over her lips, part landed on her tits, and another jet painted her neck and chin, white and thick under the floodlight. Tomás reacted in alarm, almost ashamed, trying to pull away. Nadia grabbed his arm and held him, her mouth still full, swallowing little by little.

—Easy, easy, my little one —she told him, pulling him back against her chest and smearing her face with his own cum—. Looks like you’re a real man. It all came out at once. Happens to anyone.

When he tried to wipe off what was left on him, she stopped his hand.

—Leave it. I want to taste more.

She took what was leaking between her breasts with a finger, brought it to her mouth, tasted it, and, looking toward my side, said:

—Delicious. Thick. Way tastier than yours.

She said it for me. I knew it. And I knew too, with a mix of fury and arousal that dried my throat, that I wasn’t going to sleep well that night.

***

She curled up against him, keeping him nestled at her breast while she stroked his cock slowly, unhurried, not letting it soften, until she felt it harden again between her fingers. I was hard as a rock, my nails dug into my thighs, my cock still out and dripping pre-cum.

—Look how fast you get hard again —she whispered, amazed—. You’re a machine, baby. Want to keep going?

—Yes, yes, yes.

—Want to get to know mommy’s little thing? I saw yours. That’s how people become friends, don’t you think?

He nodded eagerly while she removed the last garment. She spread her legs in front of him, showing him her shaved cunt, wet and shiny, the lips swollen and parted. When he saw her sex, Tomás froze, looking like someone discovering something he hadn’t known existed. He touched it only lightly with the tip of his index finger, tracing the slit from top to bottom. Then he slid one finger in, clumsily, and I noticed Nadia really flinch this time, not pretending, throwing her head back.

—Oh, like that, oh… —she panted—. Move it. Take it out and put it in. Yes, like that, baby.

She took his hand and taught him the rhythm, guiding his finger, then two, inside her. Her cunt was pouring, making a wet sound each time he fingered her, and Nadia started moaning openly, mouth open and eyes half-closed.

—Enough —she said suddenly, pulling his hand away—. I want you inside me. Now. Put it all in.

She made him lie on his back. She climbed on top of him slowly, resting the tip of that enormous cock at her entrance, and lowered herself little by little, biting her lip, controlling every centimeter, not letting him enter all the way, setting the pace herself. I saw her grimace when half of it was already inside, take a deep breath, and keep lowering herself until she sat all the way down on him, the cock buried to the balls. She stayed still for a second, adjusting, and then started riding him.

She rode him slowly at first, watching the boy’s face, his hands awkwardly planted on her hips and his mouth open in disbelief. Then she picked up speed. She lifted herself until only the tip stayed inside and came back down hard, the cheeks of her ass slapping against the boy’s thighs. Her tits bounced, her hair stuck to her sweaty forehead, and her mouth wouldn’t stop.

—Fuck me. What a huge cock you’ve got. You’re filling me up completely. You’re splitting me in two, Tomás. You’re ripping my cunt apart.

From my corner, the scene was tearing me in two. On one side, jealousy, that animal climbing into my throat. On the other, I couldn’t stop watching Nadia’s arched back, her hips rising and falling, the real pleasure written on her face each time she sank a little deeper, the boy’s cock disappearing all the way inside her and coming out shining with wetness.

***

At one point the boy, driven by something stronger than his shyness, grabbed her by the waist with both hands and forced her down, pinning her against his pelvis. Nadia let out a cry, half pain, half surprise, and he started moving her without restraint, lifting and lowering her by force, as if he were only now understanding what his body was for. He thrust from below with his hips, battering her with all the force of that cock, and she could only let him do it, moaning sharper and sharper.

—Oh, no, not like that, slower, slowe—oh, fuck, yes, like that, like that, fuck me like that, break me.

I got up from the chair to stop him, but Gonzalo appeared out of nowhere and put a hand on my chest.

—Easy, Damián. If you stop him, there’s no money. Look at her. Look how much she likes it.

I stayed still. Fury and arousal boiled together in me, impossible to separate. Nadia had rested her hands on the boy’s chest and was no longer controlling anything. He was impaling her from below, over and over, the wet sound of flesh slamming against flesh filling the back room. When Tomás finished, he did it with a rough grunt, gripping her waist so hard he left his fingerprints on her, emptying himself all the way inside her. They both collapsed on the platform, gasping, shining with sweat under the floodlight, a thread of cum and slick running down Nadia’s thigh.

I thought it was over. I was wrong again. Before I could get close, I saw her get on all fours, ass lifted toward the boy, offering herself. Tomás’s cock was still half-hard, shining with what he’d left inside her, and within seconds it had gone stone hard again. He grabbed her hips and entered her from behind in one single push, burying it to the hilt. This time she wasn’t pretending anything. She let out a scream that echoed through the whole back room.

—Oh, fuck your mother, yes, fuck me, come on, harder, tear me up.

Her cries filled the back room, her face was transformed, her hair falling into her eyes, her mouth drooling onto the mattress, and I, standing in the shadows with my cock in my hand, was the only witness to how much she liked it. I could see her tits hanging and swaying with every thrust, her ass reddened by the boy’s pelvis pounding into it, his cock entering and leaving her shiny, leaving my wife’s cunt open and dripping.

The scene had a filthy charge I didn’t dare name: that big, clumsy body wrapping around hers, that newly discovered strength going in and out without measuring anything, both skins slapping in rhythm. Tomás looked possessed, beside himself, one hand in her hair, yanking her upward, arching her back, while with the other he held her by the hip and used her however he wanted. Nadia let herself be carried along, biting her arm so she wouldn’t scream louder, until he came again, shooting his load inside with a roar, and collapsed on top of her, exhausted, crushing her against the mattress.

I came into my hand, unable to hold it any longer, biting my lips so they wouldn’t hear me, splattering my fingers and my pants while I watched her lick her lips and smile at me from the platform, her face still pressed against the mattress and the boy’s cum running down her thighs.

***

I climbed onto the platform in a daze. Nadia calmed me with a gesture, told me it was fine and hugged me, still breathless, sweating, the smell of sex clinging to her skin. Only one thing about Tomás caught my attention: how, the moment he possessed her, his meek face turned into that of a rutting animal, ready to attack anyone who tried to take his female away.

Gonzalo came over rubbing his hands together.

—Damián, we have to turn this into a show. We’ll make a fortune.

—No. It’s over. We’re leaving.

I waited for Nadia to get dressed, her cunt still dripping inside her panties, and took her by the arm. In the car I told her this was enough already, that we had to put an end to the whole thing. She looked at me with a calm that chilled me.

—Let me make one thing clear. You got me into this to cover your debts. You agreed to it happening, and you like the money. And don’t tell me you don’t get turned on watching me, because I know you. I saw the stain on your pants, idiot. You came watching me. I get turned on when you watch. That’s why I look for you afterward.

—Yes, but…

—Fine. I’ll stop. But if the money problems come back, you deal with them yourself.

I didn’t know what to say. I don’t know whether her decision made me happy or scared me. The only certainty is that that night, in the dark of our room, neither of us could stop thinking about what we’d seen. And I suspected, with a strange mix of relief and vertigo, that sooner or later we’d go back to that back room, to that direct light, to that chair against the wall from which I watched what I shouldn’t, and yet didn’t want to stop watching.
