Blaine drew in a sharp breath at the feel of Kurt's fingers pressing inside of him. Kurt had loosened him quite a bit with his tongue, but it wasn't really the same, and the feel of his fingers stretching him was both shocking, and rather glorious. After the initial stretch, Blaine sighed with pleasure, pressing down against Kurt's fingers for more.
"So good, baby," he murmured, eyes drifting closed as he relaxed with Kurt's touch, anticipating the moment Kurt would press his cock inside.
