Her eyes close, lashes fluttering against her cheeks when Kate does something down there with her mouth again - whatever it is, it's more than just okay, and Beckett moans a little louder at the press of a finger, slipping inside her with no trouble at all.

The sound gets cut off, lost against Bill's mouth when he yanks her in for a kiss, and her fingers grasp his hip, then move inward, the heel of her hand pressing forward against his erection through the fabric of his boxers.

Her other hand finds a place at the back of Kate's head, combing through her hair and then gripping once as she rolls her hips forward, silently needing more.
