Dinner with Our Professor Ended in a Threesome

Lucía and Diego left the shopping mall with their hearts racing. They’d been walking around the parking lot for half an hour without speaking, the car keys still in Diego’s hand, both of them brooding over the chance encounter that had just happened.

—Did you see the way he looked at you, Lucía? —Diego finally said, with a crooked smile—. Those deep eyes are just the same. He hasn’t changed a bit. He stripped you right there, between the perfume counter and the escalator.

Lucía bit her lower lip. It was a small gesture, almost imperceptible, but Diego already knew it: it meant she was more nervous than she admitted. Esteban Aldana had been her professor in her master’s program three years earlier, and ever since then he sometimes appeared in their bed talk, like a shared ghost neither of them quite dared to name.

—Diego, are you sure about inviting him to dinner? —she asked quietly—. It’s one thing to fantasize when you’ve got your hand between my legs at three in the morning, and something very different to have him in our house. What if he figures it out? What if he judges us?

Diego stopped beneath the shade of a tree and took her hand. He looked at her with that blend of tenderness and mischief that always managed to calm her.

—My love, we’re not going to tell him everything the second he walks in. We’ll have dinner, talk, see how it flows. If something happens, it happens. If not, it was a good night with an old friend. You yourself have said it a hundred times: Esteban has that voice that melts you. And you get wet every time we mention him, don’t deny it.

Lucía laughed softly, feeling the heat rise up her neck and between her thighs too. Yes, she had said it. She had repeated it in long late nights, after Diego had emptied her cunt of saliva and semen, while he stroked her back and encouraged her to put into words what she had never dared confess in daylight. “I pictured him fucking me against the whiteboard,” she had whispered once, with her mouth still full of her husband’s cock. And Diego, instead of being offended, had gotten hard again.

The week vanished in a whirlwind. Messages during university hours: “I thought of him today during the eleven o’clock class, did you?”, and a photo of her panties stained inside the professors’ restroom. Replies with emojis, promises of long nights, culinary plans, and a photo of Diego with his cock out of his pants in the office cubicle. By Friday, Lucía had tried on four dresses before settling on a black one, fitted but discreet, with no panties underneath. Diego chose a generous cabernet and some candles they’d been saving since their anniversary.

At nine, the doorbell rang. Esteban came in with a bottle in his hand and the same smile from three years ago.

***

Dinner began like a conversation between former classmates. Stories from the master’s program, whatever happened to so-and-so, where this one had ended up, how the faculty was doing. Esteban answered with his usual elegance, but Lucía soon noticed that his small dark eyes lingered on her a second longer than necessary, especially on the line of her neckline, where her nipples were already beginning to press against the fabric.

When she leaned in to pour him more wine, her hand brushed the professor’s forearm. It was a tiny touch, but Esteban didn’t pull away. Diego, seated at the other end of the table, caught every detail: the guest’s knee against his wife’s, Esteban’s finger lingering on the rim of his glass, the way she inhaled before speaking. He also noticed, because he knew her by heart, how Lucía pressed her thighs together beneath the tablecloth.

When Lucía stood up to take the plates to the kitchen, Esteban followed the contour of her hips and that round ass the black dress drew without mercy. Diego noticed. Esteban noticed that Diego had noticed. The professor lowered his eyes to his plate and his face colored with a blush they had never seen, not even in the most difficult oral exams.

—Sorry, Diego —he murmured—. I didn’t mean to be that obvious.

Diego let out a low laugh and lifted his glass.

—Relax, Esteban. Lucía has that effect. I know because it happens to me every day. And I’ll confess something: I love seeing you look at her like that.

***

The wine flowed. The lights dimmed. They moved to the sofa with fresh glasses. Lucía sat between the two men and felt the warmth of both bodies through the fabric of her dress. The conversation turned to Esteban’s years in Lisbon.

—I had a partner there for two years —he said, with the glass resting on his knee—. An open relationship, no strings attached. I learned desire doesn’t fit into small molds. Each of us would bring someone home and the other would watch, or participate, or go for a walk. It was… freeing. The first time I saw my girlfriend with another man’s cock in her mouth, I almost came just looking at her.

Diego and Lucía looked at each other. One of those looks of theirs, the kind they had been practicing for two years.

—We’ve explored something like that, Professor —Diego said, never taking his eyes off his wife—. Lucía is curious. I like seeing her curious. I like watching them eat her out and her letting them.

Esteban understood everything in that instant. He understood the way someone who has taught for twenty years understands: without a jolt, without needing any extra explanation. His hand came to rest on Lucía’s knee and climbed three centimeters with calculated slowness. Then five more. His warm palm pushed the dress fabric upward until her naked thigh was exposed. His fingers kept rising until they brushed the most intimate skin and found her without any barrier of cloth.

—No panties —he murmured, with a half smile—. You came prepared.

—How far? —he asked then, looking her in the eyes.

Lucía swallowed. Diego was watching her from the far end of the sofa, waiting for her answer, one hand resting casually on the bulge marking his pants.

—As far as the three of us want —she said, and held the professor’s gaze while opening her legs a little wider so his hand could settle in place.

***

Esteban leaned in and kissed her. Without hurry, as if he were reading the first page of a new book. Lucía answered by tangling her fingers in his nape and, without breaking away, stretched her other hand back, searching for Diego. Her husband laced his fingers with hers and kissed her bare shoulder. At the same time, the professor’s fingers sank into Lucía’s soaked folds and she opened with a moan against his mouth.

—Shit, you’re so wet —Esteban whispered, and drove two fingers inside in a single thrust.

—Let yourself go, my love —Diego whispered in her ear—. This is what we’ve talked about so many times. Let him fuck you. Let him use you. I’ll watch.

Esteban’s hands found the dress zipper and pulled it down slowly. Lucía’s breasts sprang free, her nipples already hard as stones. The professor wasted no time: he bent down and took one whole nipple into his mouth, sucking until she arched, while he kept finger-fucking her with a slow, deep rhythm. Lucía felt the cool air on her back, the weight of two gazes on her, the shiver of knowing she was being watched by her husband and finger-fucked by her former professor at the same time. Diego, never taking his eyes off her, unfastened his pants and pulled out his cock, starting to stroke it slowly.

Esteban knelt in front of her on the rug. He parted her knees with a delicacy that contrasted with the intensity of his eyes. He pushed her until she was lying on her back, her legs hanging over the edge of the sofa and her cunt open at face height. Diego came up behind, sat on the armrest, and offered his wife a front-row view of his hard cock, two centimeters from her lips.

—Open your mouth —he ordered, and Lucía obeyed.

The professor’s mouth descended along Lucía’s inner thigh with academic patience, as if every inch of skin deserved its own lesson. He bit the inside of her thigh, licked the fold of her groin, breathed against the swollen cunt without quite touching it. When he finally dragged his tongue from her entrance all the way to her clit, Lucía gave a strangled cry with Diego’s cock crossing her lips.

—God… —escaped her when she could speak, strings of saliva hanging from her mouth.

Esteban held her by the hips and kept her there, licking slowly, alternating a flat tongue over her whole sex with precise circles on the bud, then adding the pressure of his thumb while he penetrated her with two fingers curved upward, searching for the spot only Diego had found before. Lucía buried her fingers in his hair and spoke to him in whispers she didn’t even recognize as her own. Diego, above, slid his cock in and out of her mouth at an unhurried pace, letting her catch her breath whenever he felt her on the verge of losing the thread.

—Suck it slower, my love —Diego murmured, brushing the hair off her forehead—. And look at me while he finishes you.

Lucía opened her eyes and locked them on her husband’s when the first wave swept through her from head to toe. Esteban’s tongue didn’t stop while she came; on the contrary, he sped up, sucking her clit with closed lips until she convulsed, Diego’s cock still halfway down her throat. She felt her cunt clamp again and again around the professor’s fingers, and a hot stream soak Esteban’s thighs and chin.

—She came like a bitch —Diego said, satisfied, pulling his cock out of her mouth with a little wet pop—. Look at her.

Esteban lifted his face, mouth and chin shining. He smiled without wiping himself clean.

—Delicious —he said, and lowered his head again to lick up everything she had spilled.

***

What came after was a dance none of them had rehearsed. Esteban undressed slowly. When his cock sprang free of his pants, Lucía licked her lips without realizing it: it was thick, slightly curved upward, with prominent veins and a glans shining from how turned on he was. Diego handed her a condom without a word and leaned back in the chair again, his own cock out, playing the role they had silently agreed on. Before Esteban could put it on, however, Lucía dropped to her knees on the rug.

—Wait. First I want to taste it.

She grabbed his cock with both hands and took it into her mouth without further preamble. Esteban let out a guttural groan he would never have let out in class. Lucía sucked him hungrily, all the way to the base, until her eyes filled with tears and the professor felt her throat tightening around his glans. She pulled it out with a wet pop and licked his balls one by one, looking up at him with smeared makeup and hungry eyes. Diego, from the chair, stroked himself slowly, not coming yet, enjoying the show.

—Put the condom on —Lucía ordered at last, standing up—. Now it’s your turn to hold on.

She pushed the professor onto his back against the cushions and sat astride him, holding his wrists above his head. She lowered herself slowly, eyes closed and mouth open, until she felt the professor’s cock opening her cunt centimeter by centimeter. When she had all of him inside, she stayed still for a few seconds, savoring the filling.

—Now it’s my turn —she said.

Esteban, who had come into the room like a hunter, suddenly found himself on the other side of the table, pinned by the wrists of a woman who barely weighed anything and yet had him nailed to the sofa. Lucía moved with cruel slowness, dropping only to rise again, clenching around him, squeezing him with her inner muscles as if she wanted to milk him. Every time he tried to lift his hips, she bit his lip and forced him to stay still.

—Don’t move —she ordered—. I’m the one fucking.

She tore moans from him he would never have let slip in class. Diego smiled from the chair, one hand on his own cock and his eyes fixed on his wife. He watched Lucía’s ass rising and falling, how her cunt stretched around the professor’s dick each time she sank down, how her breasts bounced with every thrust. He stroked his cock calmly, with no urgency, enjoying seeing his wife fuck another man as if she owned the world.

—Give in —Lucía whispered to the professor, tightening again.

—I give in —he answered, his voice broken.

—Come for me. Now.

When Esteban exploded, he did it beneath her, trembling, head thrown back, neck tendons standing out. Lucía felt the spasms of his cock inside the condom, one after another, and kept moving slowly to wring out the last drop. She leaned down and kissed his sweaty forehead, almost tenderly, before seeking Diego with her eyes. Her husband gave her the complicit smile of someone who had just seen a work he knew by heart but had never seen performed onstage. His cock still rigid in his hand.

—Come here —Lucía told her husband, still not climbing off the professor—. Finish in my mouth.

Diego stood, crossed the few steps between them, and slid his cock between the lips of his wife, still seated on top of Esteban. Three or four thrusts were enough. He came with a growl, filling her mouth with thick semen, while Esteban watched from below, still inside her, as Lucía swallowed without losing a drop and then smiled at him with shining lips.

***

Later, already in bed, Esteban propped himself up on one elbow. His hand rested on Lucía’s hip, kneading it slowly, slipping now and then toward the curve of her ass. He looked at Diego with the same frankness with which he used to grade exams years ago.

—If you’ll allow it, I’d like to keep going with her for a while. Alone. I don’t want to abuse the night, just prolong it. I’m still hungry.

Diego looked at Lucía. Lucía returned the look with a barely hinted smile and a distracted finger stroking the professor’s sleepy cock over the sheet, feeling it come back to life.

—Go to the guest room, my love —she said—. Rest. Or imagine. You know I’ll tell you everything after. In detail. Like always.

Diego got up, kissed her lips, ran a hand through her hair, pinched a still-sensitive nipple, and gave Esteban a pat on the shoulder as he left. He closed the door quietly. The house fell silent except for the air conditioner, and Lucía turned to the professor with shining eyes.

Esteban wasted no time. He pushed her face-down onto the pillows, lifted her hips, and spread her cheeks with both hands. He ran his tongue from her clit to the other hole, back and forth, long hungry licks that made her moan into the sheet. Then he entered her in one go, all the way in, holding her wrists against the bed. They fucked like that for an eternity, in silence, hearing only the wet sounds of bodies and the air conditioner. When he turned her onto her back and put her legs over his shoulders, Lucía dug her heels into his back and begged for harder, deeper, faster, shamelessly, her voice hoarse. She came twice more before the professor spilled inside the condom with a muffled roar against her neck.

Through the wall, in the guest room, Diego listened with his eyes closed and one hand busy, smiling.

***

The next morning, sunlight came in bands through the curtains. Diego appeared with a tray: coffee, fruit, toast. Esteban, rumpled and still half asleep, sat up against the headboard and accepted the cup with a grateful gesture. Beneath the sheet, Lucía still had her hand wrapped around the professor’s cock.

—You’re a dangerously impeccable host —Esteban said.

Lucía laughed, biting into a strawberry. They spent half an hour talking about the night, what had worked, what each of them had felt. Diego was strict about those conversations; he called them the “next-day debrief” and they never skipped them. Lucía described, without filters, how she had come three times, how he had taken her from behind, how hard he had gotten again without a break. Diego listened while biting into toast, the other hand calmly beneath the sheet, stroking himself slowly.

When Esteban got up to shower, Diego looked at Lucía and winked.

—Go on. I’ll clean up.

She slid out of bed and followed the professor into the bathroom. Steam was already beginning to fog the mirror. Esteban turned under the spray and held out his hand.

—Come.

Lucía let her lingerie fall and stepped in. Their bodies met under the hot water, soap sliding between fingers. Esteban kissed her for a long time, stroked her back, went down to her buttocks and lingered there, kneading them, parting them, letting the hot water run down her crack. Lucía felt the professor’s cock harden again against her belly.

—I want one more thing before I leave —he said against her ear—. I want to come in from behind. If you’ll let me.

Lucía looked at him with that feline mischief Diego knew so well.

—Yes. But take your time. No hurry.

Esteban nodded. He was patient. He turned her slowly, pressed her against the tiles with open hands on the wall, arched her back by gently tugging her hips backward. He knelt behind her under the water and spread her ass with both hands. The professor’s hot tongue went right there, one long shameless lick over the tight hole. Lucía shuddered with her forehead against the tile, a moan escaping between her teeth. Esteban licked her for minutes, sucking, pushing his tongue a little deeper each time, while with two fingers he worked her cunt from the front to make her even wetter.

He stood up again. His soapy fingers traced circles first around the hole, then pressed slowly until one sank in, then gave way to another finger, working them in and out to prepare her, while his other hand kept her stimulated in front, pinching her clit with his thumb, so her body would surrender out of pleasure and not effort. Lucía leaned against the tiles, forehead on her arm, panting under the hot water.

—Like that —she whispered—. Slowly. A little more.

—Ready?

—Already.

When he entered, he did it centimeter by centimeter. Lucía clenched her teeth at the first invasion, feeling the head opening her ring, forcing her slowly. Esteban stayed still, breathing against her nape, giving her time. Then he pushed a little more. A little more. Until he felt her open fully around him and let out a long, surrendering moan.

—All the way in —he murmured, and Lucía pushed back once she was ready, taking control again like the night before.

Esteban held her by the hips and followed the rhythm she imposed, first slow, almost devout, each thrust a breath, and then faster, letting himself go as she asked him to with her voice and her ass. With one hand the professor found her nipples, with the other he squeezed her clit between his fingers. Lucía came with a strangled cry, her whole body tightening around the cock filling her ass, and that pressure was too much for Esteban, who spilled inside the condom with a rough groan. They finished together, foreheads pressed to the tiles, water falling over both of them, trembling.

***

Noon found them in a seafood restaurant near the sea. Diego had reserved a secluded table, in a corner half hidden by potted palms. They ordered cold beers and a spicy ceviche that burned like a private joke.

Esteban lifted his bottle.

—To unforgettable nights and refreshing mornings.

Lucía laughed, nearly spitting out a bit of shrimp. Diego toasted too, pretending to pout.

—Jealous me? Please. Last night I fell asleep listening to the moans through the wall, with my hand busy. It was a master class, Professor. Did you teach her the G spot or go straight to the doctorate?

—Doctorate —Esteban replied with mock solemnity—. With honors. And an anal thesis this morning, for the record.

Lucía nearly choked on her beer. She tossed a slice of lime at both of them.

—If you keep this up, we’re going to need the most secluded table in the place. Or just a hotel. You’re already getting my panties wet again.

—Let’s not rule out the hotel —Esteban said, and held her gaze over the rim of his beer while his hand slid beneath the tablecloth to the inside of her thigh.

The laughter continued between spicy dishes, Diego’s hand resting on his wife’s knee, Esteban’s hand idly climbing her thigh from the other side, the two meeting in the center over her swollen, still sensitive cunt, with no panties beneath her summer dress. Three bodies, one shared secret, and an implied promise that this had not been an ending.

***

On the way home, in the car with the air conditioning on full blast, Lucía turned her head toward her husband. She had that light in her eyes Diego knew: the one from late-night confessions, the one from fantasies that always ended with them fucking on the nearest piece of furniture.

—I enjoyed all of it —she said, resting her hand on Diego’s bulge—. The dinner. The night. The shower. But especially lunch. Those filthy comments turned me on all over again. I still have his semen inside me. It’s leaking through my panties while I’m talking to you.

Diego tightened his grip on the wheel and smiled without taking his eyes off the road, feeling his wife’s hand opening his fly.

—I know. Me too. Can you imagine if all this had happened during the master’s program? You walking into his office with that skirt you had, pretending to have doubts about the exam. Him locking the door. Putting you on your knees in front of the desk. Shoving his cock in your mouth while he asked if you’d studied. Me waiting outside the building, knowing everything. Watching you come out with red knees and a stain at the corner of your lips.

Lucía closed her eyes for a second while her hand closed around her husband’s hard cock.

—Keep going.

—Not now —Diego said, turning into the garage entrance—. Now, as soon as we park.

He turned off the engine. He cornered her against the seat before she even finished undoing her belt. He yanked her dress up, spread her legs, and buried his face between her thighs right there in the passenger seat, licking the professor-filled cunt with an appetite Lucía had never seen in him. Then he climbed on top of her at an impossible angle, the steering wheel digging into his back, and rammed into her. She dug her nails into his nape and bit his lip until it bled.

The entire afternoon slipped away: first against the hot hood of the car in the dim garage, then up the stairs half naked, then against the kitchen table and finally in the rumpled bed of the master bedroom. Reliving in their own bodies, in every hole, in every new moan, in every position borrowed from memory, what they had lived the night before between the three of them.
