There was no denying that Slytherins loved to gossip– you had even found yourself engaged in a rumor or two. However, when it came to your boyfriend having the hots for his best friend, you were taken by complete surprise. You had even yelled at Millicent for implying such a thing. They didn't like each other like that, they couldn't... could they?
At first, you dismissed it. They were best friends, always together, always in sync. But then you started noticing things. The way Theo’s gaze lingered a little too long when Mattheo wasn’t looking. How Mattheo’s smirk softened whenever Theo was near. The fleeting touches, the stolen glances.
And then came that night.
It started as a joke. A drunk night in the Slytherin common room. The rest of the gang were out at Hogsmeade, but the three of you stayed back. You were sprawled out on the couch, Theo sitting beside you, Mattheo lounging across from you both, his usual cocky grin in place.
Someone, maybe it was you, maybe it was Mattheo, you can't remember, threw the idea into the air like a careless spark.
“What if all three of us… you know?”
The air shifted instantly. Theo went still. Mattheo’s smirk deepened, but his eyes gleamed with something darker.
You expected laughter, maybe teasing. But instead, there was silence. A charged, heavy silence that made your stomach tighten. Then Mattheo leaned forward, elbows on his knees, eyes locked onto yours.
“Would that be a problem for you?” he asked, his voice lower than usual, almost testing.
Theo exhaled slowly, dragging a hand through his hair. His jaw was tight, his throat bobbing with something unsaid.
And that’s when it clicked. The rumors weren’t just rumors.
You looked between them—Theo, who suddenly wouldn’t meet your eyes, and Mattheo, whose smirk was still there but softer now, like he was waiting for your confirmation.
You had no idea what you’d just stepped into. But you were about to find out.
Now you’re on your knees infront of Theo, nothing new, except now you’re accompanied by his best friend.
Matty takes the lead, his warm hand wrapping around Theo’s cock. He looks at you, a wicked grin on his lips. “I know how much you like to suck him off,” he states before gesturing towards Theo. That bastard must have been talking about you. Oh well, it didn't matter now.
You lick your lips as you lean forward, sliding your tongue along the tip of Theo’s cock as Mattheo continues stroking him. You wrap your lips around his tip, tasting a bead of precum that forms at the head. Matty guides your movements gently, slowly fucking your mouth with Theo's cock. Your throat relaxes as Matty controls his pace, saliva pooling out of your mouth, dripping down your chin.
Theo’s eyes flutter shut as a loud groan erupts from his chest, pushing himself further down your throat, causing you to gag. Matty leans into you, whispering, “do you want me to take over?”
Your heart races and wetness pools at your core as his words register. Nodding, you pull back, leaving Theo slick with your spit.
Matty smirks at you, “such a good girl,” before taking Theo’s cock deep into his own mouth. His cheeks hollow out as he begins to suck hard, earning a ragged moan from your boyfriend.
Theo is whimpering as Matty bobs his head, his curls bouncing up and down, you use your free hand to tug at Theo's balls.
Without any warning to Theo, Matty pulls away; a string of saliva connecting the two of them.
"I want to watch you fuck her" Matty tells Theo and you smile at him, wiping the corner of your mouth with your thumb as you sit back on your heels.
"I guess we should give our boy what he wants,” you purr and Theo helps you to your feet, his gaze filled with lust. He takes charge, guiding you toward his bed with Matty close behind. With a gentle push, Theo lays you down, your body sinking into the soft mattres before hiking your skirt up and ripping your panties off.
"Spread those pretty legs for us," Mattheo commands, his voice hoarse with desire. Theo grips your ankles, pulling your thighs apart until you're fully exposed to them both.
Theo leans between your open thighs, pressing his throbbing cock against your slit.
"So wet already, you like watching him suck me off, huh? Such a dirty girl," he groans, grinding against you, your arousal coating his shaft.
Theo guides his hardness along your entrance, teasing you with a few slow strokes. Then, with one fluid motion, he plunges into you, making you gasp as your body stretches to accommodate him.
Mattheo stands next to you in the bed, pumping his cock in his hand vigorously. Your gaze shifts towards Matty,, his grip tight and fast as he tugs himself. Theo slams into you hard, pushing you further onto the bed.
“Good boy," Matty moans and your eyes widen, “fuck her just like that.”
Mattheo's breathing hitches as he watches Theo slide in and out of you. The wet sounds of his skin slapping against yours fills the room, punctuated by your occasional whimpers of pleasure.
Theo's thrusts become more urgent, driven by an intense need to fill you completely. "Your pussy feels amazing wrapped around my cock," he groans, his pace quickening.
As Theo pounds into you, Matty leans down and claims your lips with his own. Your mouths mash together, teeth clashing briefly as you moan into each one another.
"Fuck, I'm about to cum,” Theo grunts.
"Cum inside her," Mattheo groans.
As if the sound of Mattheo's voice turns him on, Theo lets out a final guttural groan as he spills into you, his pulsating cock shooting load after load deep inside your pussy.
As hefinishes, his cock twitching within you, Mattheo wastes no time to push him out of the way. Kneeling before you, he hooks your leg over his shoulder, revealing the hot, sticky mess between your thighs. He dives in, his tongue lapping eagerly at your slippery folds, collecting the combination of your juices and his best friend's seed.
Mattheo's tongue flicks wildly, painting your inflamed clit with Theo's hot cum as he hungrily devours the remnants of your release.
As Mattheo feasts on your swollen pussy, you feel another orgasm coiling inside you.
Your fingers tangle in his hair, gripping it tightly as he licks you. Your hips buck uncontrollably as Mattheo sucks at your clit, his expert tongue sending waves of pleasure coursing through your body. You cry out, "Oh god, don't stop!"
The coil within you snaps and Mattheo pauses mid-lick, his eyes widening as he feels the sudden flood between your legs. The force of your orgasm sends warm liquid spurting across his cheek, wetting his face and filling his mouth.
Theo chuckles in awe, you watch him carefully as he gets himself dressed.
“See what a good girl she is?” He asks Mattheo— who is speechless, wiping your cum from his chin.
