Making note of every time his breath hitched in his throat, or he made a noise louder then the others, or any kind of sign that she was hitting the right spot, she continued the further exploration of him. A small smile spread over her face when he jumped up and he twitched underneath her. Knowing that if she started this, it wasn't going to take him long, she made a decision and decided to tease him a bit. Not that she wanted him to beg or anything, she just wanted him to enjoy it. With her hands sliding over his hips, she moved all the way back so that she could run her tongue along the length of him, lapping in slow, long licks, but avoiding the head for a moment. Then finally her tongue swirled around the tip of his cock, licking up the precum and then wrapped her lips around him and slowly slid him into her mouth.
