Elena Gilbert loves Damon Salvatore's kisses, because it's not just her lips he kisses.
Elena's read smut before, obviously if those romance books with the covers that depict a woman clutching a half naked man with Fabio-long hair by the biceps under (hidden) her bed mean anything, so she'd read the phrase "kissed every inch of her body" more than enough times to know what it looked like. But until Damon, Elena didn't really know what it felt like.
(Because Damon kisses her everywhere.)
He kissed up her neck, not leaving any skin untouched by those lips of his. He kissed her on the ear (which makes a really weird suction sound and tickles like hell, but in the good way, not the kind that makes the tickle monster get hit my a pillow a million and one times) and on the sensitive skin behind it; he kissed her on the back, from the scar right above her ass to the nape of her neck when they got experimental and he kissed her fingers when she kissed his head (both of them). He kissed her breasts, her clavicle, her collarbone, her eyelids, her cheekbones, every single inch of her skin that he could reach with his mouth as he thrust in and out slowwwwwwly when they spent their first night together. And when he and his dark messy mop of hair traveled south his mouth left a wet trail from her belly-button, to her thighs, to her v, and all the way to her sweet spot.
But it's not just when they're having sex does Damon kiss her.
He looks for every excuse to kiss any inch of her available to him in that moment. A scarf, her lips. A ring, her fingers. Seeing her again, her hand. Tomato sauce, her cheek. Sometimes there isn't an excuse, and Damon will just kiss her because he feels like it.
There are times (and these are Elena's favorites, because these are the ones they're most practiced at giving each other) when the kisses don't even involve either of their lips, when labia oris aren't even in the equation.
When they're on opposite sides of the room and their eyes lock and the adoration is so obsolete that it couldn't be anything but a kiss. (Not having eye-sex, which Elena admits is much more frequent than the eye-kisses, but they exist all the same.) When they're simply talking to each other the way that they do and every single one of his words kisses her soul. Elena's not quite sure how it's possible, but Elena is quite sure Damon can kiss her in every single way possible, lips or not.
One lazy day, when their world is gray and drenched in rain and for the life of them neither of them can get up from their position of being wrapped up in each other under Elena's sheets, she asks him about it.
Damon says that he learned it when he was a human as a sort of flirtation, because kissing desirable young ladies who he wasn't promised to was such a scandal that he'd get a slap if he didn't resort to such a form of seduction.
His story is believable, and a true story because Damon doesn't lie to her she knows that much, but Elena suspects that it's just a Damon thing. Because as Damon told her, he taught Stefan how to do it too, so why didn't Stefan ever use it on her? (Elena ignored the tiny voice in her head that told her that Stefan didn't want to connect Elena with Damon in anyway. That football was one thing, but using Damon's tricks on his girlfriend simply wouldn't do.)
Damon's kisses, whether they involve lips or not it doesn't particularly matter because his kisses are hers, are one of the more public benefits of being Damon Salvatore's love.
