Summary
“Look at me, dear.” Qifrey’s voice is soft, a contrast to the fingers digging into Olruggio’s cheeks, keeping his head tilted up to face Qifrey. Their breaths mingling in the air between them, heat and sweat sticking to skin. “Good boy.”

Summary
"Qifrey," he murmured, his voice barely more than a whisper. Qifrey's restraint was wearing thin. With every second spent in this cramped room, with every minute he spent avoiding his hunger, with every day he'd fought to keep his eyes, hands, and feelings to himself. He looked up and met the fire in Olruggio's gaze. "Tell me if I'm misunderstanding."
Or,
Qifrey is a vampire and Olruggio offers him blood.Bookmarked by The_Klein_Invariant

Summary
“My feet are really aching on this floor,” Qifrey says, sighing a bit overdramatically, just for the sake of it. “There’s no rug in here or anything. And they get cold.”
“Oh,” Olly looks confused. “Do you want me to bring you—”
Qifrey cuts him off again, tipping his bearded chin up with a hand. He brushes the pad of his thumb across Olly’s bottom lip, pressing it down to see a hint of the pink inside. “Will you be my footrest, while I work?”
