Direction in this area wasn't something Clint needed, not at all, but he was more than capable of following it, especially at the lady's request.
Kate's wandering hands were enough to leave cool tingles in their wake, the muscles of his abdomen clenching a little under the light exploration before she offered a fun starting point for what she wanted.
He didn't start at her collarbone, not really. Lowering to kiss along the smooth, warm slope of her shoulder down to her collarbone, teeth dragging just a little on the sharp bones before open mouthed kisses were trailed down the sharp line to the base of her throat and then up along the other collar.
Clint kept an open hand around Kate's waist, pulling her in tight to his lower body, his stomach mostly resting between her thighs while his mouth went on his intimate explorations.
