You caught him watching you again.
It wasn’t unusual, Astarion’s eyes were always sharp, always drinking in every detail, but tonight there was something different about the way his gaze lingered. You were simply sitting at the campfire, brushing crumbs from your fingers after dinner, but the way he tracked every movement, you’d think you were performing a sin just for him.
His lips curved, pale and sharp in the firelight. “Darling,” he purred, “you really shouldn’t tempt me like that.”
You blinked, confused, until he rose and came to kneel beside you. He took your hand delicately in his, turning it palm-up. Then, without asking, he brought your fingers to his mouth. The brush of his lips was shockingly intimate, his tongue flicking against the soft pad of your fingertip before he sucked it slowly between his lips.
Heat coiled low in your stomach. “Astarion…”
“Mmm.” He hummed around your finger, releasing it with a soft, wet sound that had your heart tripping over itself. His red eyes gleamed wickedly as he leaned closer, pressing a kiss to your knuckle, then to your wrist, lingering as though tasting every inch of you was his sole purpose in life.
“You’ve no idea how often I dream of this,” he confessed in a whisper, his mouth moving against your skin with every word. “The sweetness of your lips, the curve of your throat… I want it all. Again, and again, and again.”
He kissed his way up your arm gingerly, but the hunger in his eyes was undeniable. When he reached your lips, he didn’t rush; he brushed his mouth over yours, teasing, until you were leaning forward, chasing him. That’s when he finally kissed you, like he meant to steal the very breath from your lungs.
And when he pulled back, he licked his lips and smirked. “Addicting. You see, darling? I’ll never be cured of this particular vice. You’ll just have to indulge me.”
Astarion didn’t wait for a response. His hands were already sliding to your waist, guiding you back against your bedroll. He moved with the easy grace of a predator, settling himself above you, but his touch was gentle and teasing, maddeningly slow.
“Relax for me,” he whispered, his lips brushing yours between words, “I want to savor you properly.”
His mouth returned to yours, greedy and hot, tongue tracing every inch like he was memorizing the taste. But he couldn’t stay there long, his fixation was pulling him further, dragging his kisses down your neck. He sucked at your pulse, biting just enough to make you gasp, then soothing the mark with his tongue.
Every inch he touched, he claimed. Along your collarbone, your shoulder, the soft curve of your chest, each kiss wetter, hungrier. His hands pushed aside fabric with impatient elegance, baring more of you to his mouth.
“Gods, you’re decadent,” he groaned, kissing over your ribs, your stomach, lingering just below your navel. His eyes flicked up to meet yours, glowing with wicked delight.
He pressed his lips against your skin there, breathing you in before trailing lower. His kisses grew sloppier, open-mouthed and hungry, his tongue dragging heat over sensitive skin. He moaned against you, as if you were the sweetest meal he’d ever had.
When his mouth reached your thighs, he spread them apart achingly slow, placing gentle kisses down one side, then the other, always just shy of where you needed him. He grinned at the way you shivered.
“Oh, my sweet thing,” he purred, his breath hot against your core, “this is where I’ve wanted to be all along.” His lips brushed close enough to make you tremble, but he drew back with a low chuckle. “Beg for it, darling.”
His fangs glinted as he hovered there, torturing you with every hot exhale. The hunger in his eyes was unmistakable, he wasn’t going to stop until he’d worshiped you with that sinful mouth of his.
“Gods, please, I need you, Astarion!”
His smile curved, triumphant, before he lowered his head and gave in to the fixation he’d been dancing around for weeks.
The first drag of his tongue over you had your back arching, a sharp whimper escaping before you could stop it. He groaned against you like he’d just tasted the rarest wine, clutching your thighs to keep you open for him.
“Sweet gods…” he muttered, breaking away just long enough to kiss your inner thigh, his lips wet and swollen already. His eyes gleamed as he looked up at you, hair tumbling into his face. “I told you, didn’t I? Utterly addicting. You’re going to ruin me.”
And then he buried himself in you.
His mouth sealed over you, tongue stroking and curling with devastating precision, greedy and insistent. He moaned with every taste, each sound vibrating straight through you. His hands tightened on your thighs, keeping you spread as he feasted, alternating between long, indulgent licks and quick, sharp flicks of his tongue that made your toes curl.
Every time you gasped his name, he hummed, like your voice itself was something he wanted on his tongue too. He kissed, sucked, bit just enough to make you tremble, only to soothe with soft, wet strokes that left you quivering. He couldn’t get enough, kissing you sloppily, messily, pulling back only to lick his lips and dive right back in, more ravenous each time.
“You taste like sin itself,” he rasped against you, his voice ragged with hunger. “And I’m damned, darling...I don’t care if I never stop.”
Your body trembled under his unrelenting mouth, pleasure winding tighter with every swirl of his tongue, every sharp suck that left you crying out for him. He devoured you like he’d been starving for centuries, because, in truth, he had. And now he had found his favorite meal.
When release finally shattered through you, he didn’t stop, if anything, he grew more desperate, groaning against you as though your pleasure only fed his obsession. He held you down with trembling strength, drinking every last wave, until you were shaking beneath him.
Only then did he lift his head, lips wet, chin slick with you, his smirk absolutely sinful. He licked his mouth slowly, savoring every trace of yout cum, before leaning over you to press a kiss against your lips, letting you taste yourself on him.
“Delicious,” he purred, his voice low and thick with desire. “And you, my sweet, are mine to feast on whenever I please.”
