Black Butler, Sebastian/Ciel, marks
Ciel bites down on Sebastian's gloved hand as Sebastian's cock pushes oil-slick and hot into him. He wants to rip the glove off, to taste Sebastian, but Sebastian is gagging him with that hand, bending low over him as he pulls Ciel's hips back, and all Ciel can do is scrabble at the bedding and bite down hard on the cloth. It tastes like flour, like nothing, and Sebastian is moving in him. It shouldn't feel so good, he shouldn't enjoy being spread open and helpless underneath Sebastian.
But it's Sebastian, who won't hurt him, and who's doing nothing but wring pleasure from Ciel with a soft glove around his cock as he fucks him, despite Ciel's teeth deep in his hand. His rhythm is slow and deep, unhurried, and when Ciel comes with a low, strangled noise low in his throat, Sebastian is still moving.
When Sebastian finally comes and pulls out, Ciel is trembling, all over. He can't control it; it's Sebastian's fault for making him feel this way, for making him raw and weak. He scowls and turns on his side with far too much effort to tug at Sebastian's glove-- he can see blood in his teethmarks, but when he pulls the glove off, Sebastian's skin is whole and unblemished, and the only mark on him is the contract symbol.
"You're mine," Ciel says, and he grabs that hand to pull it towards him as he closes his eyes. When he presses it to his chest, where his heart's starting to slow down, he can feel Sebastian like electricity in his veins, and the sensation lulls him into sleep.
