The four of us had settled everything during a night of wine and a conversation that went on far too long, just among ourselves. A throuple turning into a foursome, later sealed with that one rule that made the blood boil: total fidelity within the circle. No one brought anyone in from the outside.
It was Friday. Marina arrived first, still smelling of her work perfume, but already kicking off her heels at the door. She looked at me and smiled in that way that said, “I want everything tonight.” She kissed my mouth slowly, her hot tongue exploring, while her hands already slid under my t-shirt, squeezing my breasts as if they had belonged to her for years.
From the sofa, Lucas and Theo watched, calm, glasses in hand. Lucas, my boyfriend since forever, was the quietest of the four, but the one who liked to control the rhythm the most. Theo, the youngest, tattooed, with that crooked smile that made Marina wet just by looking at him. They kissed too, without haste, mouths meeting while Marina pushed me against the living room wall.
“You two… come here,” she called, her voice husky. “I want to feel everyone at the same time.”
Lucas stood up first. He came up behind me, his large hands wrapping around my waist, his hard cock already brushing against my butt over my shorts. Theo approached Marina, kissing her neck while unzipping her skirt. The clothes hit the floor in seconds. Marina was naked, her dark skin glowing, breasts firm, her pussy visibly wet, lips swollen with lust.
And then everything exploded.
Marina knelt down first. She pulled Theo’s cock out—thick, with prominent veins—and began to suck slowly, looking at me while she did it. I knelt beside her, licking the base of his shaft along with her, our tongues touching halfway, salty with pre-cum. Lucas came behind her, fingers spreading her legs, two fingers entering her slick pussy at once. Marina moaned with her mouth full, the vibration traveling up Theo’s cock.
“Fuck… yes… fuck her with your fingers while we suck him,” I said, my voice trembling with heat.
Lucas obeyed, thrusting his fingers rhythmically, the wet sound filling the room. Theo held both of our hair, guiding our mouths. “Look at them… look at how Marina grips Lucas’s fingers… she’s dripping.”
Marina came first, fast and hard, her body shaking, moaning loudly around Theo’s cock. The fluid ran down Lucas’s fingers, dripping onto the floor. She turned, kissing Lucas with the taste of herself in his mouth, then pulled me on top of her on the rug.
“I want both of you inside me at the same time,” she whispered to me and Theo.
Theo lay on his back. Marina climbed onto him, fitting his cock in slowly, letting out a long moan as she slid down to the base. I positioned myself in front, riding his face in reverse, my pussy rubbing against his hot mouth. Lucas stood to the side, cock in hand, masturbating slowly as he watched. Marina leaned forward, sucking my clitoris while she moved up and down on Theo’s cock. I felt her tongue circling, hot and hungry, and Theo’s mouth devouring me from below.
Lucas moved closer. “Open up more for me, love,” he said to Marina.
She arched her back, pushing her butt up. Lucas spat on his hand, rubbed it on his cock, and entered her pussy slowly alongside Theo—double, stretching, filling. Marina screamed with a pleasure mixed with a good kind of pain, her whole body shaking. “Holy shit… this is it… two cocks in my pussy… fuck deeper…”
I came in Theo’s mouth watching that: Marina being stretched by both of them, moaning hoarsely, nails dug into Theo’s thighs. My body convulsed, liquid running onto his face, and he licked it all up, grunting.
Then we swapped. Lucas took me from behind, thrusting hard while I sucked Marina, who was sitting on Theo’s face again. Theo came first, filling her pussy, cum leaking out when he pulled away. Marina turned around, spreading her legs for me: “Clean it, Sofia… eat his cum out of me while Lucas fucks you.”
I shoved my tongue in, licking the saltiness mixed with her sweet taste, feeling Lucas drive deep into me with every lick. Theo recovered quickly, coming behind Lucas, lubricated fingers entering his ass slowly—Lucas loved that, moaning loudly, his cock pulsing harder inside me.
Marina came again in my mouth, squeezing my head between her thighs. Lucas couldn’t hold back: he thrust deep and came inside me, filling everything. Theo pulled his fingers out, masturbated quickly, and came on Lucas’s back, hot cum running down.
We all collapsed on the rug, sweaty, breathless, bodies glued together. Marina laughed softly, kissing my messy mouth: “This… just the four of us. Always like this. No one else gets in.”
Lucas draped his arm over everyone, his voice deep: “Polyfidelity isn’t just a rule. It’s desire. It’s knowing that all this fire stays here… only here.”
Theo added, hand on Marina’s chest: “And tomorrow we do it again. And the day after. Until we get tired… or we never get tired.”
I smiled, my pussy still throbbing, feeling the cum from both of them slowly running down my thighs. Nothing in the world made me wetter than knowing that pleasure was exclusive. Ours. Closed. Multiplied by four.
