“Well I’ll just go and fuck somebody you care about then!” Theo screams, his cheeks flushed. He’s so angry he could burst. He wants to do something reckless. Stupid.
“Oh yeah? Who?”
He thinks about what would hurt Harry the most and the answer is blindingly obvious. The man in question’s footsteps tread heavily down the corridor, surely coming to enquire about the noise. A large hand, tattooed and calloused, pushes the door open.
“What’s going on?” Sirius asks with only a transparent white linen shirt covering his lightly toned chest. Slacks made from a soft grey cotton cover long legs. Theo takes him in from head to foot. He’s always found the man to be temptingly fuckable but since he’s Harry’s godfather, Theo has always kept his distance. Now, however… Now he couldn’t give two fucks. Shagging Sirius would make Harry understand the pain he’s caused him by fucking Draco and he hopes it burns something wicked.
“Harry was just trying to explain that it’s okay that he cheated on me.”
Sirius’ nothing-can-bother-me face falls into one of disappointment. And Theo’s breath hitches when that then turns into anger.
“You did what?”
Harry shrugs, a lump in his throat.
“No, go on,” Sirius prompts, “Defend yourself as you were to Theo. I’d like to hear it.”
Theo wants to smile especially when Sirius snakes his arm around his shoulders, pulling him close into his side as though in protection.
“I was only saying that I was drunk!”
“And that’s a good enough reason to hurt the man you’re supposed to love? How would you feel if Theo slept with someone you’re sensitive about? That’s his best friend.”
“Draco can make his own decisions,” Harry grumbles. “Theo would never do such a thing. He loves me.”
Theo’s blood boils, his temper is bubbling to the surface, his hands feel empty of touch, he wants to throw something, hurt something, and he knows the only way how. He pulls down on Sirius’ open shirt and kisses him once.
“Theo, what the fuck?!” Harry yells, stepping closer.
The greying man blinks twice, turns to face Harry, sees the anger in his eyes, and nods at Theo.
“Do you know what you’re doing?” He asks, a cracked and husky grumble to his voice, affected by lust, driving Theo mad.
“I was hoping you would but I’m sure about this.”
“Good,” Sirius drawls and hoists Theo over his shoulder to drop him on the end of Harry’s bed.
“Sirius…” Harry’s tone becomes firmer.
“Sit down, little boy,” Sirius snaps, flicking his wand to push Harry back into an armchair facing the bed. Ropes tie over his arms, his thighs, his ankles and Theo laughs before he sees the power in Sirius’ eyes.
“Let me treat you right,” he whispers, placing a gentle kiss on Theo’s lips, snapping his fingers to remove Theo’s clothes. Under Sirius’ stormy eyes, he feels desired. Theo feels strong even as he prepares to submit everything to this man protecting him. He tells him to lower his face to the bed, to lift up his gorgeous hips because Daddy is hungry for a taste and Sirius’ tongue is unmatched for skill. So greedy and so generous. Theo writhes as that tongue licks him from tip to base and higher, wetting his ‘perfect’ hole.
“Stop this right now,” Harry struggles.
“Did my cousin taste as fucking delicious as my boy?” Sirius growls, placing two large hands on Theo’s cheeks, kissing along his spine. Never has Theo been loved like this or had so much time spent on readying him to receive.
“I’m your boy?” Theo whimpers, turning over his shoulder to see affection in otherwise dangerous eyes.
“Of course you are. Look at you. So good for me. For Daddy. I’ll look after you.”
Theo nods, accepting Sirius’ kiss, loving the way Harry’s lip curls like that, like he can do anything to stop this.
“What would you like me to do next?” Sirius asks, softly stroking Theo’s length.
A fiery soul isn’t only a Gryffindor quality, Theo thinks as his gaze burns hot into his former lover.
“Fuck me so hard that Harry regrets it. Every fucking second.”
Sirius lets out a cock-pulsing chuckle from the bad of his throat. So ready, such a man in comparison to Harry.
“It’ll hurt,” he explains, sliding his calloused palm along Theo’s smooth back. He grins, his chest heaving, thoughts of Draco and Harry hot and heavy spurring him on.
“Good.”
With that, Sirius teaches his god-son a lesson, pounding into his ex-lover with abandon.
“Gods, Harry,” he pants. “How can anybody feel better than this good boy? You’ll miss this. You’ll miss the way he worships you with his eyes. They’re mine now. He’s mine. I’m keeping him. My cousin better have been worth it.”
Theo keens, arching his back, feeling every inch of the man claiming him, turning his legs to liquid, making him see that he had been wasting his time with Harry anyway. That Draco can have his sloppy seconds because he’s found something better. He’s found a man who can take care of him, knowing instinctively what he needs, who reads his face, reads his body like he wrote the fucking script for how it functions. Sirius spits into his palm and brings Theo off with a hand right around his length and his cock buried deep.
Theo’s release comes in waves, the first that it ever has, and ruins Harry’s bedsheets in spectacular fashion, and Theo hopes his cheating backstabbing ex remembers this every fucking time he lays his head down to sleep. Theo will, of course. Because he’ll be laying his own on Sirius’ chest, claiming something that Harry has never had.
A daddy of his own.
