Blaine's entire body shuddered at the gentle feel of Kurt's lips pressing there, only to change to the feel of broad strokes of his tongue, wet and warm. He was quickly turning into a quivering mess, fingers tightening in Kurt's hair, toes curling into the bedsheets, as he tried very, very hard not to move his hips too much in need.
Worst still was the desire to moan. He bit his lip hard to keep his sounds muffled, the metallic taste of blood spreading over his tongue. But god, it felt so good, and everything Kurt was doing was amazing.
