It felt so good to have him use her this way – and looking up, she saw him struggling to maintain his composure. That she was the cause for his fracturing self-control was both arousing and unbelievably flattering. His dark eyes met hers and then he thrust rapidly, filling her throat to the hilt with every thrust, clasping her hair to hold her head in place as he fucked her throat with abandon. She did her best to apply suction or use her tongue, but at this pace (and with her wrists restrained) the best she could truly hope for was not to choke. With a groan, he came, spilling his seed down her throat. She coughed in surprise and then swallowed down what she could, tonguing his head and shaft lightly as he withdrew.
