Blaine continued to pay special attention to Kurt's balls for a long moment, lapping at them with his tongue before lifting them in his hand, rolling them between his fingers as he slid further, nudging at Kurt's thighs with his shoulders. He licked a quick, playful stripe down Kurt's perineum, blowing air over the skin lightly and then paused, closing his eyes and just breathing in the musky scent of Kurt all around him, heightened from their previous exertions.
Tongue darting out in soft, teasing swipes, Blaine moved down the cleft of Kurt's ass, barely brushing over the puckered skin around his entrance, moving his head instead to press a kiss at the edge of a perfectly rounded cheek.
