Phone sex with Sherlock has definitely been one of her past fantasies. Even under normal circumstances his voice can make her mouth go dry. Having him use that voice to tell her how he would perform oral sex on her is even better than she could have ever imagined.

"I want your mouth so bad," she breathes out, her hips moving with the hand in her knickers and the other coming up to massage her breast.
