Teddy bends to lick into James’s already parted lips, probably unintentionally pushing his cock in a tiny bit more. James groans into his mouth. Teddy then whispers against his lips, “I saw you watching him again last night.”

A searing heat flares up James’s spine. His eyes widen before he can turn his face away, but turn he does. “Teddy, no…”

“It’s true, though.” Teddy strokes a strand of hair off James’s face. “Merlin, even your freckles are blushing.” He says this smiling, enamoured. Teddy settles his hips in the cradle of James’s pelvis and murmurs in his ear, “It’s okay.”

“It’s absolutely not okay.”

“Is with me,” Teddy smirks, beginning to rut inside him again, building to a slow rhythm. “Pretty sure it is with him, too.”

“Merlin, Ted.”

“Will this be easier if you don’t have to look at me?”

At James’s small, guilty nod, Teddy pulls out. He flips James over onto his stomach. Tender hands massage his buttocks, and James makes a desperate sound into the pillow—before he’s jerked up onto his knees, and Teddy lines his cock up and pushes back inside.

“You watched him dancing with that bloke and his girlfriend,” Teddy says, easing in and out, cock slipping easily through the abundant lube. “I saw how jealous you got, his body between them, the three of them writhing.”

“Bloody hell, I don’t want to relive it,” James growls.

“I know. I’m sorry.” Teddy’s strong hands smooth up his back. “He doesn’t feel about them the way he feels about you, though. How could he?” Then he says those fateful word, his cock punctuating them, shoving it all into James at once: “You’re his brother.”

James tenses, and Teddy groans as his arse tightens down. “You feel so fucking good, Jamie. I wonder how he’d feel… sliding his cock in alongside mine.”

“Ohhh,” James cries, burying his mortified face. And yet his cock hasn’t flagged. In fact, it’s leaking a stream now.

“You know he’ll do it. He was looking at you too. He always looks at you.”

A sickening sort of hope fills James’s chest at that. He doesn’t want to ask if what Teddy says is true… If Albus watches James like James knows he watches Al. If it could possibly mean the same thing even if he does.

Teddy fucks him steadily, and James can feel his boyfriend’s magic gather… feels the swish of the wand that fits itself to Teddy’s hand. Teddy’s Patronus.

“Oh god, Teddy, please,” James begs.

“Do you trust me not to hurt you?” Teddy asks. He’s pulled out, and he’s rubbing the head of his dick around James’s loose rim, sending tendrils of lust straight into James’s stiff cock.

“You know I do,” James groans.

“Look how stretched open you are,” Teddy muses. “I want to see you stretched even wider, Jamie.”

James buries his face again, widening his knees. He wants it so bad he’ll soon beg; he knows himself.

“What do you want?”

“I want you to fuck me.”

“I know, honey. What else?”

“I want you, Teddy, please.”

“And?”

James loses his breath; he can’t speak.

Teddy inserts the head of his cock. “Tell me, Jamie.”

“I want…”

“Yeah?”

“I want… him.”

Teddy exhales, and James can sense him restraining his own desire, even as he drives his cock in slowly. “Say his name.”

“I want him,” James says again, the simultaneous shame and desire coursing through him in waves. “I want Al,” he finally gets out. “I want Albus.”

The soft gasp from the doorway douses James in icy fear, followed closely by licks of flame. He turns his head and sees Albus standing there, his eyes widened, cheeks pink. Albus’s gaze takes in the scene: his brother on his knees, taking Teddy’s cock from behind. James presses his eyes into his arm, trying to blot it all out, his little brother’s stunned expression, his own naked body, every part of him visible, the words he’s just said, the light in the room.

“I got your Patronus,” Al says in a daze.

Then James hears Albus’s steps—not leaving the room but entering.
