The way he looks up at her and the sounds he's making increase her pleasure tenfold and her own whimpers join with his. She bites her lip and concentrates on what's making her feel good and what's hopefully making him feel good.

"Sherlock," she whispers as her hips grind against his. She's chasing another orgasm, can feel the ache become urgent.
