Toxic
Severus is leaving after this year, graduating Hogwarts. Regulus knows he should end it, should learn to resist the toxic addiction that is Severus, but he never quite gathers the courage when Severus's black eyes are gazing into his with that wide-eyed, rapt attention that makes him feel like the most important thing in the world. And Severus is always staring at him.
It's almost as if he knows what Regulus is thinking, sometimes. He stares, and then somehow knows exactly what Regulus wants him to do. He seems to get off on giving Regulus the perfect shag, and this is a little weird to be thinking about when Regulus is spread-eagled on the floor of the dungeon room, writhing in agony and pleasure, while Severus lingers somewhere near his groin and does ungodly things with that tongue of his.
Severus stretches his arms out without looking up and takes Regulus's hands, giving him something to hold on to as he arches his back and cries out. The feeling of bliss passes, and he's left with a deep satisfaction that somehow isn't as satisfying as it used to be, because he knows Severus is leaving.
Regulus is still stretched out on the floor, unmoving, as Severus gathers his robes up off the cold stone. He watches while Severus dresses and shakes out the wrinkles and dust.
"Aren't you cold?" The words are spoken while Severus has his back turned. It takes Regulus a moment to realize Severus is actually talking to him.
"Not really," he says truthfully. He's still feeling the heat from Severus's ministrations and trembling with exertion.
"You will be, soon. You have to take care of yourself, Regulus." Severus is still facing the other way, smoothing out his robes. "I won't be here much longer to do it for you."
"Is that what you call it? Taking care of me?" Regulus's voice comes out oddly, like he's being strangled. He's not sure if he's going to laugh or cry.
Severus turns around and collects the pile of Regulus's clothes. "Here," he says, and he drops them on top of the younger boy. "I'm taking down the warming charms."
"The – what?" Regulus sits up, staring at him. "What warming charms? The floor is always cold."
"In the air, circulating from the ceiling. You take forever to dress." Severus pulls out his wand and makes several sweeping motions. Suddenly the air feels a lot colder, and Regulus shivers. "Get dressed, Reg. I'll see you later."
It's the first time Severus has used his nickname. Regulus watches him leave and realizes he left the cleaning charms on the floor.
