Stefan couldn't help but grin when he saw her features begin to shift. She was still so new, she couldn't hold back the vampire in her at times like this. It was strangely sweet and endearing and it only made him want her more. He lowered his head once again, not too fast so she didn't end up ripping his hair out, his mouth replacing his thumb once again on her clit. After a moment of suckling, harder than he had been doing before, he pulled his hand away from her altogether so he could run his tongue down her wet folds before slipping it inside her, as deep as he could, shutting his eyes as he savoured the taste of her. He bobbed his head back and forth a few times, fucking her lazily with his tongue, before he pulled out and resumed his oral assault on her clit, replacing his tongue with two skilled fingers instead of one. He could feel his cock, hard against his stomach, between him and the couch. It felt as though it were throbbing with the borrowed blood in his veins, he was so turned on. But he wanted her to come before he let himself have her. This was about her, not him. That was the way he liked it.
