Oh, fucking hell. His mouth was so good it was almost making Chas' body feel weak, which made it a really good thing that she was pinned between him and the wall. The pain from his teeth mingled with the pleasure she was getting, encouraging her noises to grow even louder. She made use of the surface against her back, riding him as she angled her hips to create even more friction between them.
Her head fell to his shoulder, not to muffle her sounds but so that her teeth could bite sharply into his skin. Not quite hard enough to draw blood, but very close, and oh hell was she tempted. As she bit him, her hands gripped at his back, nails digging deep into his skin even as her heels dug into his arse, pulling him deep and hard inside her.
