Since MOST of you have read this series I decided to do a side by side of both Jace and Wills perspectives of their first kisses with Tessa(for Will) and Clary(for Jace). 
 Here you go: 
 "'You know, when most girls say they want a big rock, they don't mean, you know, literally a big rock.'" 
 He smiles without meaning to. Which is unusual in and of itself; usually only Alec or Isabelle can startle laughter out of him. He had known Clary was brave the first time he'd met her -- walking into that room after Isabelle, unarmed and unprepared, took the kind of guts he didn't associate with mundanes -- but the fact that she made him laugh still surprised him." 
 -Jace, City of Bones 
 "'You never laugh,'" she was saying. "'You behave as if everything is funny to you, but you never laugh. Sometimes you smile when you think no one is paying attention.'" 
 He wanted to close his eyes. Her words went through him like the clean slice of a seraph blade, lighting his nerves on fire. He'd had no idea she had observed him so closely, or so accurately. "You," he replied. "You make me laugh. From the moment you hit me with that bottle. Not to mention the way that you always correct me. With that funny look on your face when you do it. And the way you shouted at Gabriel Lightwood. And even the way you talked back to de Quincey. You make me . . .'" 
 -Will Herondale, Clockwork Angel 
 "But this girl, with her green eyes that pinned him like a butterfly, she was real." 
 -Jace, City of Bones 
 "--she only stood still, watching him like a curious bird. He did not think he had ever seen someone with eyes the color of hers before: it was the color of gray mist blowing in from the sea in Wales." 
 -Will Herondale, Clockwork Angel 
 "And he sees: there is some sort of mark on her shoulder, a scar, but he sees more than that: he sees the curve of her collarbone, the light dusting freckles on her skin like a dusting of gold, the downy curve of her shoulder, the pulse at the base of her throat. He sees the shape of her mouth, her lips slightly parted. Her coppery lashes as she lowers them." 
 -Jace, City of Bones 
 "He could hear himself breathing. Heat spread through his body -- not the unnatural heat of vampire sickness, but the more ordinary flush of desire. The skin of her wrist was translucently pale, the blue veins visible beneath.He could see the flutter of her pulse, feel the warmth of her breath against his cheek." 
 -Will Herondale, Clockwork Angel 
 "And he is swept through with a wave of desire, a kind he has never experienced before. He's desired girls before, certainly, and satisfied that desire: he had always thought of it as hunger, a need for a sort of fuel that the body wanted. 
 He has never felt desire like this, a clean fire that burned away thought, that made his hands -- not tremble, exactly, but thrum with nervous energy. " 
 -Jace, City of Bones 
 "He had kissed girls, other girls, when basic physical desire overcame common sense, in dark corners at parties or under the mistletoe. Quick, hurried kisses, most of them, although some surprisingly expert -- where had Elspeth Mayburn learned how to do what she did with her teeth, and why had no one ever told her it wasn't a good idea? -- but this was different." 
 -Will Herondale, Clockwork Angel 
 "Her mouth opened under his, hesitant, and some corner of his mind cried out to him to slow his pace, that by any reasonable guess this was her first kiss. He forced his hands to slow down, to gently unclasp the fastenings in her hair and smooth the curls down over her shoulders and back, his fingertips tracing light patterns on her soft cheekbones, her bare shoulders. Her hair felt like warm silk running through his fingers and her body, pressed against his, was all softness. Her hands were light as feathers on the back of his neck, in his hair; when he drew her closer, she made a low sound against his mouth that nearly drove every last thought from his head. He began to bend her back toward the floor, moving his body over hers --" 
 -Will Herondale, Clockwork Angel 
 -"And he is astonished. He doesn't work like this; his body doesn't do things without his permission. It is his instrument as much as the piano, and he has always been in perfect command of it. But she tastes sweet, like apples and copper, and her body in his arms is trembling. She is so small; his arms go around her, to steady her, and he is lost. He understands now why kisses in movies are filmed the way they are, with the camera endlessly circling, circling: the ground is unsteady under his feet and he clings to her, small as she is, as if she could hold him up. 
 His palms smooth down her back. He can feel her breathing against him; a gasp in between kisses. Her thin fingers are in his hair, on the back of his neck, tangling gently, and he remembers the medianox flower and the first time he saw it and thought: here is something too beautiful to properly belong in this world. "
