Kate drags a slow line of kisses higher and higher on Beckett's thigh, nuzzling and nipping at the sensitive skin, the actions as careful as they are taunting.

Feeling Beckett shiver, she licks at the crease of Beckett's thigh in response, her tongue running over silky skin and the edge of Beckett's underwear.

Mouth hovering over Beckett's hip, her hand dips lower between Beckett's legs, the pads of her fingers ghosting down Beckett's center. Lifting her eyes to look at Beckett and Bill, a half-smile tugs at her lips as she circles Beckett's clit through the thin material, movements molasses-slow and butterfly-light.
