He wasn't planning on stopping any time soon, not until he's kissed, licked, or sucked on every part of her body. (Biting doesn't factor. Too violent. Perhaps she can tell he's holding back just a bit.)

He moves down her body slowly, then back up again, making prolonged stops at parts of her that are especially sensitive. He's at her lips again when he's through, kissing her with far more confidence than he ever had during their previous kisses. He realizes it's an expression of possession. He suddenly pulls away, trying to cover up his sudden discomfort by burying kisses into her neck.
