Threesome with My Professor and a Classmate

I don't usually tell these kinds of stories, but that afternoon stayed etched in my mind because of how well it turned out and how far we decided to go. It all began with private tutoring sessions from Mara, an adult literature professor who was known for being strict, elegant, and far too sure of herself. I was barely passing another subject, and a classmate, Lucía, convinced me to ask her for help because she'd already been to her office more than once.

The help soon became mixed up with something else. Mara wasn't a shy woman, and the way she spoke slowly, corrected me up close, and rested a hand on my shoulder as if she knew perfectly well what effect it had on me turned me on. The first time she masturbated me under the table, I understood that she didn't want mere gratitude; she wanted control.

That was what started to bother me. I liked fucking her, yes, and it really turned me on to see her spread her legs with the attitude of a woman who knew how to give orders. But every encounter ended the same way: she decided the pace, the position, when I could touch her and when I had to stay still. After several afternoons like that, I wanted to turn the tables.

Lucía was the first person I told. She was an adult too, went to the tutoring sessions for another reason, and had already flirted with Mara in front of me without hiding it very much. One afternoon, on the way out, she told me that the professor had kissed her against a bookcase and that she still couldn't stop thinking about her tongue. That's when I knew something bigger could happen.

The third was Bruno, a friend of mine with an innocent face and the soul of a son of a bitch. When I told him I had something going on with a professor and a classmate, he laughed like a bastard and asked for details. I gave him almost all of them. I explained that Mara swallowed my cock as if it were a prize for herself, that Lucía got wet just from hearing her moan, and that I was tired of obeying.

—I want you to come in at exactly the right moment —I told him that afternoon, sitting in a bar downtown—. Catch her almost naked with her phone in her hand. You don't even have to show anything to anyone; as long as she thinks you can, that'll be enough.

Bruno raised his eyebrows, amused.

—And afterward?

—Then you fuck her if you feel like it. But really. No just watching.

He took a drink and let out a low laugh.

—Damn, now I'm interested.

I spent the rest of the week thinking about the scene. In the shower, I imagined it with such clarity that it made my cock hard in seconds: Mara kneeling, Lucía with her legs spread on the table, Bruno coming in with that thug's grin, and me finally taking the situation wherever I wanted. I came that morning before leaving home, squeezing my cock with my soapy hand while fantasizing about Mara's ass trembling beneath thrusts she wouldn't be controlling.

I went to the office a little early. I'd put on comfortable clothes and wasn't even wearing underwear because I wanted to get naked quickly. When I entered, I saw a couple of metal trays full of folders on a side cabinet; they were heavy enough to make a hell of a racket if I knocked them over. I smiled. I already had the signal.

Mara arrived a few minutes later. She was wearing a dark skirt, a fitted blouse, and that clean perfume that always made me want to bury my face between her tits. Her hair was tied back, her expression calm, and she had the confidence of someone who believed she owned the territory.

—You're on time today —she said, closing the door behind her.

—I didn't want to miss my reward.

She smiled with soft malice. Lucía appeared right afterward, greeted us naturally, and sat on the edge of the large office table. We all already knew that meeting had nothing academic about it.

—I promised you a reward if you improved —Mara said, approaching Lucía first—. And I like to keep my promises.

She kissed her unhurriedly. Lucía responded by opening her mouth to her tongue and grabbing her ass over the skirt. I watched them for a few seconds, feeling my cock harden instantly. Mara shot me a sidelong glance, as if she wanted to remind me that she was still in charge even while kissing someone else.

She came over to me and rubbed my bulge through my trousers. She did it expertly, moving her hand exactly where I felt the most tension. I breathed out through my nose, restraining myself. Lucía was already unbuttoning Mara's blouse, and when the fabric opened, her full, firm tits appeared, held by a simple bra that didn't stay on for even half a minute.

—Sit down —Mara ordered.

She said it in that tone that used to turn me on completely. I sat in a chair in front of her. She knelt, yanked down my trousers, and pulled out my hard, heavy cock, already wet at the tip. Lucía positioned herself behind Mara, lifted her skirt, and moved her underwear aside. Seeing the professor with her pussy exposed and my classmate putting her hand between her legs pushed me to the limit.

Mara licked my glans slowly, looking up at me. She knew how to suck like a specialist: first her tongue around the tip, then her mouth sliding down little by little, squeezing just enough, leaving plenty of saliva so that every pass made me tremble. I grabbed her hair reflexively, but she immediately pushed my hand away and fixed me with her eyes.

—No. I'm in charge here.

That was the last thing she said before everything changed.

Lucía had already put two fingers inside her pussy and pulled them out dripping. Then she lowered her head and began eating her from behind, spreading her buttocks with her hands and burying her tongue between her wet lips. Mara let out a short moan without taking my cock from her mouth. I watched her gag halfway while Lucía licked her, and it was a brutal spectacle: one sucking me, the other making her moan, and me about to trigger what we'd prepared.

I pushed the metal trays with my foot.

The crash against the floor was sharp, loud, impossible to ignore. Mara raised her head in alarm. Lucía straightened up. And in that second the door burst open.

Bruno came in with his phone in his hand, recording. He closed the door with his foot and smiled when he saw the scene: the professor on her knees, her blouse open, her skirt raised, my cock out, and Lucía's mouth glistening with wetness.

—Well, well —he said—. What a complete lesson.

Mara stood up abruptly, red with rage.

—Turn that off right now.

—Are you sure? —Bruno lifted the phone a little higher—. Because it would only take a minute for this to spread everywhere.

Lucía said nothing. She looked at me. I held Mara's gaze, and for the first time I saw her hesitate. She didn't lose her arrogance, but I could see her calculating, the speed with which she understood that she wouldn't be the only one deciding that afternoon.

—What do you want? —she asked at last.

Bruno approached slowly, put away the phone without stopping his smile, and pulled out his cock in front of her. It was already half hard.

—To start with, I want you to use that mouth on me.

Mara looked at me with a mixture of fury and arousal that heated me even more. She knew perfectly well that this wasn't accidental. She could have shouted, walked out, or slapped all of us. Instead, she took a deep breath, knelt again, and opened her mouth for Bruno.

That was when the afternoon really began.

While she swallowed my friend's cock, I lifted Lucía and sat her on the table. I opened her legs and found her pussy already soaked. Her lips were swollen, her clitoris hard, and she had a filthy look that asked me for more without speaking. I ran my tongue from bottom to top, from her entrance to her clitoris, and she let out a long moan, throwing her head back.

—Don't stop —she said—. Eat me properly.

I grabbed her thighs and did it without rushing, sucking her clitoris, licking her entrance, alternating with two fingers inside her that came out wet and went back in deeper. Lucía writhed on the wood, pushing my face with her pelvis. When I moved lower and ran my tongue over her ass, she spread her legs even farther and let out a hoarse moan.

—There, you bastard... just like that.

I ate her ass for a while, burying my tongue while I rubbed her pussy with my hand. I felt her tense. I went back up to her clitoris and she came on my face, trembling and gripping my hair hard. She soaked my mouth and chin, and I kept licking until she began begging me to ease up because she couldn't take any more.

Behind me, Bruno was already fucking Mara's mouth shamelessly. He had her hair gathered in one hand and was pushing himself down her throat, pulling out covered in saliva. Mara tried to maintain control by bracing her hands on his thighs, but every thrust left a wet, obscene sound that filled the office.

—Look at me —Bruno told her—. That's it. Suck it properly.

I climbed onto the table, and Lucía knelt between my legs. She sucked my cock eagerly, without putting on an act, like a genuinely horny woman. She went down as far as she could, swallowed, came back up, and licked my frenulum precisely. My cock was throbbing so hard that I had to hold her head for a second to make her stop, because if she kept going I'd come right there.

Mara pulled away, coughing a little, with her mascara barely smudged and her mouth shining. She turned toward us, and I saw her expression change: she was still angry, yes, but she was also incredibly turned on. Her legs were pressed together, and her pussy was wetting the insides of her thighs.

—Now it's your turn —I told her.

I put her on all fours on the office carpet. I lifted her skirt all the way, moved aside her underwear, and saw her pussy open and wet, begging for cock. I ran my hand over her buttocks and shoved two fingers inside her. Mara moaned, lowered her head, and pushed back.

—More —she said through clenched teeth—. Don't leave me like this.

Lucía lay on her back beside her and brought two fingers to her pussy, watching us as she slowly pushed them in and pulled them out. Bruno positioned himself in front of Mara so she could suck him again. I took advantage of that moment to slam my cock into her pussy with one hard thrust.

Mara screamed with her mouth occupied. I drove into her all the way at once and stayed still for a second, enjoying how tightly she squeezed me inside. She was hot, slippery, and very open with arousal. I began moving slowly, setting the pace myself and holding her hips.

—You don't command anything like this —I whispered in her ear—. Today we're fucking you.

Her answer was to push her ass backward, asking me for more. I sped up. Every thrust made a wet, thick sound, and her pussy milked my cock as if it wanted to wring me dry. Bruno kept putting himself in her mouth, alternating with rough caresses on her cheeks, while Lucía had moved closer to kiss one of her tits, biting her nipple as I fucked her.

The scene became a delicious chaos of hands, saliva, and moans. Lucía got underneath Mara, between her legs, and began licking her clitoris while I penetrated her. I felt the pussy contract around my cock and the professor's legs tremble. Bruno forced her to swallow him again just as she began to come.

Mara had a brutal orgasm. She went rigid, then her arms buckled and she nearly fell to the floor. Her wetness splashed my balls and the carpet. I didn't stop. I kept fucking her while she came, harder each time, taking advantage of how sensitive she was to pull even filthier moans from her.

—Fuck... yes... yes... like that... —she stammered when Bruno released her mouth.

I pulled out for a moment and smacked her ass. Then I pushed two fingers, lubricated with her own fluids, into her anus, first one and then the other. Mara tensed, but she didn't pull away. On the contrary, she spread her legs wider and rested her forehead on the floor.

—Slowly at first —she murmured, almost panting.

Lucía smiled when she heard her. She came closer and spat between Mara's buttocks before inserting another finger to open her a little. Seeing my classmate prepare the professor's ass gave me a direct jolt in the stomach. I grabbed Lucía's hair, kissed her with saliva and the taste of pussy, and then focused on Mara again.

I put it back in her pussy while Lucía continued playing with her ass. I could feel exactly how her fingers moved on the other side, how she moaned at the double sensation, how she opened even wider. Then I pulled away and looked at Bruno.

—Your turn back there.

Bruno didn't hesitate. He spat on his cock, positioned himself behind Mara, and pressed the tip against her anus, already opened by Lucía's fingers. The first entry was slow and tense. Mara gritted her teeth and let out a deep groan, half pain, half pleasure. Bruno stayed still for a second, letting her get used to him.

—Fuck, what an ass —he said, gripping her hips.

I lifted Mara's face so she would look at me, and while Bruno began moving in and out of her ass with short thrusts, I pushed my cock back into her pussy. That was when she completely lost her composure. The breath left her, a hoarse cry escaped her, and she began moving the hips trapped between the two rhythms.

We fucked her like that for quite a while. Me in front, in her pussy; Bruno behind, in her ass. Lucía at her side, kissing her mouth whenever she could, sucking her nipples, rubbing her own pussy with two fingers as she watched us. The office smelled of sex, sweat, and ruined perfume. The impacts of our pelvises against Mara's body echoed off the walls.

—Harder —she finally begged—. Don't treat me gently.

That was what I wanted to hear. I squeezed her hips and began thrusting her with genuine force, sinking all the way in and pulling almost completely out before driving myself into her again. Bruno did the same from behind, using her without mercy. Mara moaned without restraint, saliva running down her chin and her tits swaying with every blow.

Lucía positioned herself in front of her and put two fingers in Mara's mouth. Mara sucked them without stopping receiving cock from the front and back. It was such an obscene image that I almost came just from seeing it. I held back, biting air, and kept pounding her.

After a few minutes I pulled my cock from Mara's pussy and dragged Lucía down to the floor. I laid her on her back, lifted her legs, and thrust into her. She was so wet that I almost slipped inside. She let out a muffled laugh that immediately turned into a moan when I began fucking her at a quick, continuous pace, taking advantage of how aroused she'd already been.

—Like that, like that... don't stop —she told me—. Fuck me hard.

I grabbed her hips and devoted myself to driving into her all the way. Her pussy squeezed me like crazy. Every time I pulled out, she left my cock covered in glistening fluid, and every time I went back in, I drew a new moan from her. Lucía wrapped her legs around me and scratched my back, pulling me closer. I lowered my hand and rubbed her clitoris while penetrating her, and that sent her to the edge immediately.

Behind us, Bruno continued with Mara. He laid her completely facedown and brought her legs a little closer together so he could fuck her ass with more pressure. She moaned against the carpet, one hand beneath her body and the other gripping a chair leg. Every so often she lifted her head to look at Lucía and me while I pounded her with my cock on the floor.

Lucía came first. Her stomach tightened, she squeezed me with her legs, and she lay trembling beneath me while I gave her a few more thrusts. I couldn't hold out much longer afterward. I came inside her pussy with a deep shudder, exhaling sharply and letting myself collapse on her body for a second.

But the afternoon wasn't over.

We separated, panting. Lucía, still breathless, knelt beside Mara and began masturbating her from the front while Bruno fucked her from behind. I approached the professor, put two fingers in her mouth, and told her to suck them. She obeyed without moving her ass away from the thrusts. Then I slid those same fingers over her clitoris and felt her wet again.

—You like being used by everyone, don't you? —I said to her.

She didn't answer with words. She pushed against Lucía's hand, Bruno's cock, and my fingers all at once. Her entire body was saying yes.

Bruno came in her ass shortly afterward, with several sharp thrusts and a low grunt. He stayed motionless for a moment, buried to the hilt, then slowly pulled out. Some of his come trickled between her buttocks. Lucía, without the slightest disgust, ran two fingers through it and showed them to Mara before putting them back in her mouth. The professor sucked them with her eyes half closed.

My cock was already hard again. The quick recovery of that age had its advantages, and seeing the spectacle got me hard without any effort. I made Mara turn around and sat her in a chair. Lucía crouched between her legs to eat her pussy again while I approached from the front with my cock in my hand.

Mara opened her mouth on her own this time. She sucked me with more hunger than at the beginning, as if, after everything, no trace of pride remained, only desire. I pushed her head gently at first and then with more authority, setting the pace for her. Lucía kept licking her clitoris and working her tongue inside her, so Mara moaned with my cock in her mouth, the sound vibrating against my glans.

I didn't last long like that. I pulled out, ran my cock over her face a couple of times, and came over her open mouth and chin, leaving my cum on her lips. She closed her eyes, breathed deeply, and cleaned herself with her fingers before slowly sucking them. Watching her do it left me empty and satisfied.

All four of us lay scattered around the office, catching our breath. The afternoon light had almost disappeared, and only the desk lamp remained on. Mara rearranged her blouse without much haste, though her skirt was still crooked and her face looked as if she'd been fucked in every possible way.

—You were bastards —she said at last, looking first at me and then at Bruno.

—Yes —I answered—. But it doesn't look like you had a bad time.

Lucía gave a short laugh and rested her head on my shoulder. Bruno shrugged, satisfied like a well-fed animal. Mara watched us for a few seconds and finally smiled with a mixture of exhaustion and brazenness.

—Next time —she said— don't put on a show. Just call me.

The three of us looked at each other and laughed. The best part wasn't merely getting our revenge on her in our own way; it was discovering that beneath all that need for control, Mara got just as turned on as we did by losing it for an entire afternoon.

By the time we left the building, it was already night. I still carried the scent of all three of them on my skin, my cock was half-sensitive, and I had the feeling that I'd crossed a line I had no intention of returning from. And I knew, without needing to say it, that office was going to be too small for everything we still had left to do.
