"Come over this afternoon, I need your help organizing a surprise for Mattéo's birthday. You're the best at this kind of thing ;)"

That was the message Emma had received from her sister-in-law that morning. Emma really liked Zoé, Nathan's "attachiante" (It's a French expression to say that someone is endearing and annoying at the same time) little sister, with whom she spent a lot of time and with whom she had become a true friend over the years.

After a difficult breakup, and a considerable number of guys who had passed through her bed, she seemed to have finally found love again in Mattéo. A bit too macho for Emma, ​​but hey, she wasn't the one living with him.

Emma arrived cheerful and smiling in front of Zoé's building and enthusiastically pressed the intercom button.

"Come up and go straight in, I'll leave the door open for you."

Emma went up to the third floor and found the door ajar as she'd been told. She went in, took off her shoes to feel the parquet floor beneath her bare feet, and closed the door.

"Zoé?" Emma asked. Receiving no answer, she entered this place she knew so well and headed towards the living room. She had barely stepped through the door when she froze, breathless.

In the living room, Mattéo stood, his muscular, imposing body completely naked.

Kneeling before him, only Zoé's head moved, the wet, intimate sounds leaving little doubt as to what she was doing.

Emma went pale. "Oh my God…" she murmured, unable to look away.

Zoé continued without pausing, gently hollowing her cheeks. Mattéo fixed his blue-gray eyes on Emma's, a macho, arrogant smile on his lips.

"I... I'm sorry, I'm going to…" Emma stammered.

"Shut up," Mattéo said simply, his voice low, calm, but firm.

He placed his enormous hand on his girlfriend's head to dictate the pace. Zoé seemed to be sucking with more focus, but Mattéo didn't take his eyes off Emma, ​​most likely imagining the redhead on her knees at his mercy. The raw desire she perceived in his eyes made her feel a mixture of unease and excitement.

"I'm leaving... I'm leaving you guys," Emma stammered, without much conviction.

"No. Stay," ordered Matteo as he thrust his hips hard into Zoé's mouth. His voice was calm but authoritative.

The sight unfolding before Emma was unbearably erotic, unleashing all the demons she desperately tried to keep locked away.

Only a few minutes passed before Matteo began to groan deeply, firmly holding Zoé's head and staring at Emma. She remained pressed against him until the very last drop, trembling with small spasms that Zoé seemed to accept with pleasure and devotion.

As Mattéo gradually loosened his grip, Zoé slowly pulled her head back from her boyfriend's crotch and rose with feline grace before turning to Emma, ​​her lips sealed. She approached slowly under Mattéo's watchful gaze. Her sister-in-law stopped just inches away. She then tenderly cupped Emma's face in her hands and drew her face closer to kiss her.

Instinctively, Emma took a step back, her heart pounding. She had always had a soft spot for Zoé but she never dared to go any further on the subject.

Zoé remained perfectly still, her face close to hers. A gentle, patient smile stretched across her lips. Then, without a word, she slowly opened her mouth. A phenomenal amount of thick, white semen coated her tongue, almost overflowing her mouth. The liquid glistened, viscous, and still warm. Emma held her breath, both horrified and fascinated (excited?).

She slowly closed her mouth, swallowed a tiny sip to tease her, then approached with calculated gentleness. She half-closed her eyes, a smile still playing on her lips. One of her hands slid delicately around Emma's waist, drawing her close. The other hand rested in her auburn hair, gently gliding through the strands.

At the first touch of Zoé's lips, a violent shiver ran through Emma's body. This touch, so soft, so intimate, instantly awakened the weakness she had always felt for the blonde. Emma remained motionless. Her eyelids slowly closed and she surrendered.

As soon as their lips truly touched, Zoé began to gently force her way inside with her tongue. The kiss began almost timidly: her tongue brushed against Emma's, slowly and sensually pushing a first wave of warm sperm into her mouth.

Then passion took over. Zoé deepened the kiss with growing eagerness, her tongue entwining with Emma's, forcing its way in, transferring more and more semen in a wet, obscene exchange. Her delicate hand tightened in Emma's hair, pulling harder while her other hand, resting on her waist, pressed her against her body.

Thick strands of semen mixed with their saliva trickled from the corners of their mouths.

Zoé broke the kiss slightly, just enough to whisper against Emma's trembling lips, her voice soft:

"I've been waiting for this moment for a long time... ever since that night when your tongue loosened after a few shots of tequila. At first, you said the taste of semen didn't bother you... and then you finally admitted it obsessed you. That you thought about it often."

Emma went pale instantly. Her eyes widened in terror. She had vague memories of that evening, blurry and embarrassing fragments. She had long hoped she had imagined it all, invented those humiliating confessions. And she had been reassured to see that Zoé behaved exactly as usual in the days that followed… until today.

Zoé smiled against her mouth.

"You hoped I’d forgotten, huh?" she murmured, sliding her tongue between Emma’s lips again, playing with the semen that was still present on their lips. "But I haven’t forgotten anything. And today, I’m proposing a win-win arrangement."

She resumed the kiss with more passion, her hand gripping Emma’s hair tighter, forcing the redhead to play with the hot, degrading mixture while white streaks continued to trickle down her chin.

Mattéo slowly approached until he was only a meter away from the two girls, still completely naked. His cock, now completely hard again, stood proudly erect, thick and veined, still glistening with Zoé's saliva and the remnants of his first orgasm.

Zoé finally stopped, but she kept her face pressed close to Emma's, their noses brushing against each other, their hot, ragged breaths mingling. A glistening trail of semen still connected their swollen lips.

"Do you like it?" Zoé murmured in a low, provocative voice, her eyes shining with excitement.

Mattéo replied without hesitation, his voice hoarse and deep, never taking his eyes off Emma: "Yes."

Zoé smiled, satisfied. She gently stroked Emma's cheek with her fingertips before adding, "And it's time for your present..."

With a firm but controlled movement, she pressed down on Emma's shoulders, forcing her down. Emma hesitated for a fraction of a second, her heart pounding, but she didn't resist for long. Her knees bent, and she found herself on her knees on the rug, her face level with Matteo's imposing cock.

Zoé didn't waste a second. She slipped her hand into Emma's red hair, gripping a tight handful as if holding a mane. Then, with almost arrogant confidence, she guided her friend's head forward. Matteo's thick cock first brushed against Emma's lips. Zoé pressed a little harder, gently but firmly forcing Emma's mouth open. The thick head slid between her lips, stretching her mouth as Zoé began a slow, steady motion, as if she were jerking off her boyfriend with her sister-in-law's mouth.

“That’s it… take it,” Zoé murmured warmly close to Emma’s ear, without letting go of her hair.

She guided Emma’s head up and down Matteo’s sex with a precise rhythm, pushing a little deeper with each stroke. Emma’s saliva was already flowing freely along the thick shaft. Matteo groaned with pleasure, his abdominal muscles contracting.

Zoé quickened the pace slightly, pushing Emma's mouth a little deeper onto her boyfriend's thick cock.

"Deeper, Emma... be a good girl," she breathed with a dominant smile, firmly maintaining the rhythm. Mattéo's breathing became heavier, his hand resting on Zoé's head in approval, but his gaze remained fixed on his cock, which seemed to disappear further and further between the lips of the redhead kneeling before him.

"But isn't she engaged or something?" Mattéo whispered.

Zoé sneered, an arrogant smile on her lips, while still firmly gripping Emma's red hair.

"Why? Are you planning to marry her?"

Matteo clenched his jaw.

"No, but... it's about your brother."

Zoé then pushed Emma's head a little further onto Matteo's large cock, pushing several more centimeters into her mouth. Emma let out a muffled moan, her eyes moist, as her throat tightened around the head.

"And you expect me to believe that you're not turned on by fucking the mouth of my brother's fiancée?" Zoé retorted in a mocking and excited voice, "Especially since you can't stand him..."

She held Emma down for a few more seconds before letting her catch her breath, a long string of saliva connecting the redhead's lips to Matteo's glistening cock.

"You know what...", Zoé continued, her eyes shining, "Go ahead and have fun. Fuck her mouth."

Matteo didn't hesitate for a second. He grabbed Emma's hair with both hands, his large palms almost completely enveloping her head. With a powerful, controlled thrust, he began to fuck her mouth. His thick cock slid in and out between her stretched lips, hitting the back of her throat with each stroke. Wet, obscene sounds filled the living room, saliva dripping down Emma's chin and onto her top. Emma was now moaning around him, completely lost in the lust of the moment, tears welling in her eyes, but she didn't pull away. On the contrary, it even seemed as if her head moved forward of its own accord. She was in a state of rare arousal, the animalistic situation reminding her of that event that had opened her Pandora's box and revealed to her the unknown pleasures of submission.

Zoé, aroused by the scene, sat down in the nearby armchair, one restless hand slipping between her pants and her burning skin as she watched her boyfriend take control.

"That's good... fuck her harder," she murmured. Matteo groaned with pleasure and ordered in a low, authoritative voice, "Get on your knees and help her."

Zoé chuckled while continuing to enjoy herself, "No, it's your birthday, my love, I'll let you enjoy it alone."

Matteo quickened his pace, now fucking Emma's mouth more forcefully. His thick cock plunged deep into her throat with each thrust, his wet balls slapping against the redhead's chin. Tears streamed down Emma's cheeks, saliva dripping onto her breasts as she struggled to breathe between brutal strokes.

Zoé stood up and slid behind Emma, ​​pressing her voluptuous body against her friend's back. Her firm breasts pressed against Emma's shoulder blades as she wrapped her arms around her.

"Look at this little slut...", Zoé growled in Emma's ear, her voice low and venomous. "My brother's fiancée on her knees, her throat full of my boyfriend's cock. Nathan would be so proud..."

With one hand, she grabbed Emma's breast through her top, roughly kneading it and pinching the already hard nipple between her fingers. With the other, she slipped without hesitation under Emma's waistband, inserting her fingers into her panties. She immediately found her friend's wet entrance and began to caress it with quick, firm, circular motions, rubbing her swollen clitoris.

Emma moaned violently around Matteo's cock, the sound muffled and vibrated by the large shaft that filled her mouth.

Zoé slowly licked Emma's neck, then sank her teeth into her soft skin, sucking and nibbling while her fingers moved faster and faster inside her panties.

"You're soaking wet, Emma..." Zoé sneered in her ear. "You've always dreamed of getting pounded by a real man while your fiancé plays his video games, haven't you? Show me."

Mattéo, meanwhile, was completely letting loose. He held Emma's head in both hands like an object, fucking her mercilessly. His thick cock went in and out of her throat in brutal, deep movements, making her cheeks swell with each thrust. Obscene, liquid noises echoed in the living room: violent gurgles, smacking skin, spurting saliva.

"Damn, that slut, I can feel her sucking me in now..." Mattéo groaned through his teeth, the veins in his neck bulging.

Zoé quickened her fingers inside Emma's panties, now pushing two fingers deep into her wet core while continuing to pinch her nipple.

"Do you hear that?" she murmured, licking Emma's earlobe. "He's calling you a slut and you're getting even wetter. Come on, let it all out, come, my beauty, you need it. I can feel it."

The intensity was at its peak. Emma trembled between them, sandwiched between Matteo's muscular body as he brutally pounded her orally and Zoé's sensual body as she caressed and dominated her from behind.

Emma exploded.

Her body arched abruptly between them. A long, muffled cry vibrated around Matteo's cock as a violent orgasm washed over her. Her sex contracted fiercely around Zoe's fingers. She trembled, her legs weak, her eyes rolling back, wracked by uncontrollable spasms. Zoé sneered maliciously as she continued to finger her throughout the orgasm.

Matteo felt the vibrations of Emma's cries around his cock and lost control. He thrust his pulsing hardness deep into the redhead's throat and came with an animalistic groan.

"Take it all, bitch!"

Powerful, copious jets of hot semen gushed directly into her throat. He continued to thrust brutally, emptying every last drop into Emma's mouth, forcing his thick semen down into her stomach. He remained deeply embedded for long seconds, his balls clenched against her chin.

When he finally withdrew slowly, Emma collapsed onto all fours, trying to catch her breath. She coughed weakly, breathless, her chin and upper body completely soaked, her eyes glazed after the intense orgasm she had just experienced.

Zoé removed her fingers from Emma's panties, brought them to her own mouth and slowly licked them with a triumphant smile.

Emma was still panting, her chin and lips covered in a thick mixture of saliva and semen. Her eyes were glassy, ​​her body still trembling from the spasms of the orgasm Zoé had just wrested from her.

"Thank you for the birthday present, baby," Mattéo murmured in a hoarse voice. "It was the best I've ever had."

Zoé gave her a knowing wink before gracefully crouching down in front of Emma. She slipped two fingers under her chin and gently lifted her face, gazing into her eyes. Then she placed a tender, almost loving kiss on her lips.

"Thank you, my dear..." she murmured against his lips, her voice soft and velvety. "I hope you enjoyed the taste of my man. Maybe I'll let you taste him again sometime... who knows?"

Emma was lost in a thick fog of pleasure and shame, unable to respond.

Mattéo, for his part, hadn't lost his erection. Seeing Emma on all fours only heightened his excitement. He knelt behind her, placed his large hands on her hips, and with a sharp thrust, pulled her buttocks against him, eliciting a small cry of surprise from her. His hard, still-glowing length pressed against the crease of her buttocks through her jeans, leaving a wet and obscene mark.

“Wait…” Zoé interjected with a mischievous little smile, still gripping Emma’s chin. “Your present was just a blowjob. Nothing more.”

Mattéo groaned, a hint of frustration visible on his face, while firmly holding Emma's hips.

“Not today, at least,” Zoé added in a slightly purring voice. She slowly stood up, giving Mattéo a look full of lust. “Seeing you so animalistic with her turned me on like crazy. Come on… fuck me now.”

While talking, she began to remove her clothes, revealing a set of refined black lingerie that he adored: a balconette bra in fine lace that perfectly accentuated her generous breasts, and a matching thong that highlighted her round hips and firm buttocks.

She approached him and added, almost in a whisper:

"If you make me come at least twice... You'll have Emma all night. No limitation this time."

This promise finally convinced Matteo. His gaze left Emma's body and settled on Zoé with obvious hunger. Without another look to the redhead, still on all fours, they headed towards the bedroom. The door slammed behind them.

Emma remained alone in the middle of the living room, still on all fours, her body trembling. Her face glistened with sweat, saliva, and semen. Her red hair clung to her cheeks, and her vagina throbbed, wet and empty. She still couldn't grasp what had just happened. If Zoé hadn't stopped Mattéo… she wasn't even sure she would have protested. In fact, she probably would have begged him.

Obscene noises were already reaching her from the room: Zoé's increasingly loud moans, the regular and powerful slapping of skin against skin, and Mattéo's deep grunts.

Emma closed her eyes. Her trembling hand slid down between her thighs. Her fingers found her hypersensitive, dripping sex. She began to caress herself, slowly at first, then faster and faster, rubbing her swollen clitoris while inserting two fingers inside herself.

Zoé's cries grew louder and louder, "Yes! Harder!"

Emma sped up, involuntarily imagining the scene unfolding behind the door. Her body was on fire. She pinched her nipple with one hand while violently fingering herself with the other.

A few minutes later, a long, high-pitched scream from Zoé echoed through the apartment.

That was the trigger.

Emma exploded in a violent, solitary orgasm. Her body arched abruptly, her thighs trembled as she came hard, her fingers dripping with her own juices. A hoarse, ashamed moan escaped her throat as waves of pleasure washed over her.

She then lay panting on the rug, her body covered in fluids, her mind completely blank, still listening to the muffled sounds of Zoé and Mattéo still making love in the bedroom.
