Summary
Newt is stalling. He can admit that to himself. He never intended to stay in New York this long, but he keeps happening upon reasons not to leave. It’s so easy to find excuses to come upon Graves in hallways, to arrange little meetings and opportunities to deliver reports, and he tells himself its necessary, but it isn’t. Not for any worthwhile purpose, at least. Each time that Graves’ fingers end up in his mouth the need gets a little stronger, and on a bodily level, it does feel necessary.

Summary
Gellert is always purposeful in the modifications he makes. Getting it just right is important to him, and everything is tailored to fit the pet in question. In particular he enjoys accentuating whatever parts of their personality they fear or dislike the most, transforming them until that’s the only thing left.
Percival was deeply uncomfortable with the softer, caring side of himself. Theseus struggled with his impulsiveness and baser desires. Newt feared being trapped and caged. Credence loathed the helpless submission he’d been forced into his whole life. Tina is caught between her compassion and her ambition.
Each piercing Gellert gives them works inexorably, irresistibly, until all that's left is a collection of lewd playthings.

Summary
“My boy,” Graves greets him, and Credence needs only the slightest indication that he’s welcome before he steps into Graves’ arms.
The kiss is just unsettling enough for Credence to take notice. Graves is leaving him room to participate rather than simply claiming him, and it takes Credence a moment to adjust to his expectations. Graves seems pleased enough with the effort though, and Credence is just glad to have him home. Graves pulls back, taking Credence’s cheek in his palm and looking him up and down.
“Tell me, what is your favorite of the things I do to you?”
There’s no doubt, Credence doesn’t even stop to consider. “When you fuck my cock, sir.”

Summary
“You and I, we need to have a little chat.” Grindelwald picks up the end of the chain and wraps it around his fist, tugging just hard enough to ensure Credence’s total attention. “Look at me.” Credence raises his eyes to meet Grindelwald’s, and there’s an intensity to his gaze which is unnerving. Grindelwald usually looks past him, as though he were a piece of furniture he’s grown accustomed to seeing. Now, however, his full focus has come to bear on him. There’s a pull to his gaze, like Grindelwald has his own inexorable gravity, and Credence is starting to feel its tug.

Summary
It wasn’t until that evening, curled up in the surprisingly comfortable nest he had made with the mattress and blankets on the combined space of the trunk and the folded-down backseat, that he allowed himself to open the magazine and get a better idea of how much trouble he was in.
Jason Thompson, son of OmegAid founder John Thompson, has helped countless alphas find and rehabilitate their wayward omegas. Now the 28-year-old alpha will be utilizing the company’s resources to rescue his own omega: On Sunday, August 11, Thompson caught his bondmate’s scent outside a café while on a business trip to Baton Rouge. He tracked the scent to a nearby apartment complex, but by the time he managed to gain access to the inside of the building, the unit his nose led him to was empty, with clear signs of having been abandoned in a hurry.
—
Remy was a modern, working omega who knew exactly what he wanted his future to look like. But when his destined bondmate, the traditionalist alpha heir to an omega "rehabilitation" company, suddenly appeared outside of his home, he had no choice but to go on the run for any chance at keeping his freedom.- Language:
