Chas was taking the biting and scratching thing farther than Kevin had experienced before, but he couldn't say that he minded. Breaking his skin got a little cry from him, but he muffled it against her throat, and combined with the way she was tightening around him, he barely felt the real sting of pain.
He was close, tensing in the double circle of her arms and legs, biting down just as hard on her throat and growling a little as he worried at the skin, fingers curling into her skin at the same time as his toes curled into the floor. He was getting rougher as he got closer, wanting to bring her over the edge with him, but his release hit before he could do much to hold it back, and he gave a muffled groan of her name against her skin.
