"Alright, come on. Admit it. They're good, right?" Stiles asked with his mouth full. It was more endearing than it should be. Then again, this was Stiles, and Derek absolutely loved and adored everything about him.

Derek rubbed his thumb in circles on Stiles's shoulder as they cuddled up on the couch, eating their faux s'mores, which were Nutella and marshmallow fluff spread over graham crackers. And Derek had to agree, they were pretty damn good.

He took another bite of one, savoring the rich chocolatey flavor that exploded on his tongue. The sweetness of the marshmallow fluff perfectly contrasted with the creamy Nutella. He looked over at Stiles who appeared to be eagerly waiting for his reaction.

"Well," Derek chuckled, wiping off some marshmallow fluff from the corner of his mouth, "I have to concede. They're not just good—they're delicious."

Stiles beamed at the compliment, looking immensely satisfied with himself.

"And you thought I was crazy when I suggested it," he teased, stealing another graham cracker and assembling another faux s'more for himself, clearly delighted with Derek's approval. "At least this way, we don't have to sit out in the cold by a fire."

The temperature was starting to drop at night, and while it didn't bother Derek, thanks to being a werewolf and running warmer, Stiles was human. The last thing Derek wanted was for him to get sick. Besides, he preferred being happily tucked away inside, under a warm blanket with Stiles by his side.

The crackling fire from the television screen filled the room with a cozy ambiance, making it the perfect setting to enjoy their indoor s'mores. Stiles handed Derek another one, his eyes shining with mischief.

"I've got more culinary surprises up my sleeve," Stiles retorted, biting into his s'more with a satisfied hum.

"Well, you've definitely earned some points tonight," Derek admitted, laughter in his eyes. He bit into the s'more, sitting up when the Nutella began to drip down his chin.

Stiles chuckled and instead of wiping the chocolate away or handing Derek a napkin, he leaned over, licking the droplet of Nutella from Derek's chin to the corner of his lips.

Derek's breath hitched in surprise, his cock twitching as heat pooled in his groin. Fuck. And just like that, he had to have Stiles. Now. He raised a brow in silent challenge, fingers flexing as he lowered his hand to Stiles's hip.

"Oh, is that how it is?" Stiles laughed, turning and straddling Derek's lap before running his hands up Derek's chest. His eyes grew dark with desire, a playful smirk on his lips, his scent spicy-sweet with his arousal.

All Derek could do was grin, his eyes not leaving Stiles's as he thrust up, showing Stiles exactly what he was getting himself into. He whispered into Stiles's ear with a gravelly voice full of hunger and desire. "Are you going to finish what you started?"

Stiles's smirk turned into a cheeky grin at Derek's challenge.

"I always finish what I started," he retorted confidently, his fingers leaving a trail of goosebumps as he drew them down Derek's chest, stopping just above the waistband of his jeans. He locked eyes with Derek, the heat in his gaze only intensifying.

"Well then," Derek retorted, a growl slipping out, causing Stiles to shiver. "By all means."

It became a mess of limbs as they undressed until they were skin on skin and Derek sighed with relief as Stiles settled back on his lap, the tip of his cock dampening Derek's belly. Anticipation coiled in Derek's stomach. The evening had taken an unexpected yet excitingly pleasant turn. It was light, playful, sexy—and tantalizing—the perfect mix of comfort and heated desire.

"How's this?" Stiles asked as if he knew he was killing Derek and was enjoying the torture.

Derek swallowed thickly, running his hands up Stiles's thighs. "Perfect. You're perfect."

And God, he was. Especially when he threw his head back, exposing the long line of his neck.

"Give me your mouth," Derek demanded. If he didn't kiss Stiles right now, he felt like he'd combust.

Stiles nodded, and their playful banter quickly morphed into a slow, passionate dance of lips as Stiles kissed him. It was sweet, flavored with marshmallow fluff and Nutella, and above all else, Stiles.

God, Derek could never get enough of him. He swatted a hand out, feeling for the drawer of the side table, where they kept the lube. Well, one of the bottles. They had them stashed everywhere and anywhere because they couldn't keep their hands off each other. Bedroom, bathroom, kitchen, living room…it didn't matter.

"Get yourself ready for me," Derek said, coming up victorious as he found the bottle.

Stiles plucked it from his hand, opening and squirting some into his palm before slicking up Derek's cock as he shook his head. "Uh uh, wanna feel you stretch me open."

Derek laughed, the sensation causing him to jerk in Stiles's hand. "Impatient tonight, aren't you?"

"Only for you," Stiles replied with a wink, his hand squeezing Derek's cock, making him gasp. "Now how do you want me?"

Derek growled in response, his hands immediately settling on Stiles's hips. "Ride me."

His heart battered against his chest wall as Stiles's hot, tight body slowly—so damn slowly Derek thought he would die—lowered around him. Stiles was incredible, so fucking perfect.

As soon as Derek was buried to the hilt, he pulled Stiles in by the back of the neck, pressing their foreheads together, his eyes locked on Stiles, heavy with passion and need. He sat there for a moment, breathing heavily before whispering, "I love you."

"I love you too," Stiles replied softly, his hands cradling Derek's face. With a slow grind of his hips, he started moving, riding Derek in a slow, deliberate rhythm. Their bodies moved in a practiced dance, their sighs echoing throughout the living room.

With their eyes still locked, Derek's hands roamed freely over Stiles's back, occasionally dipping lower to feel the curve of his ass as Stiles rode him, setting a pleasurable pace. Stiles clenched tighter with every downward move, making Derek groan, growl, and plea for more.

They went fast and hard, then slow and tender.

Derek wrapped his arms around Stiles, face buried in the crook of Stiles's neck, muttering praises and nonsensical words that only seemed to spur Stiles on more. The way Stiles moved drove Derek wild, especially combined with the sound of their pants, the wet slide of them together.

"Harder, Derek," Stiles begged, his voice was huskier than Derek had ever heard it.

Derek wanted to oblige—every part of him yearned to give Stiles exactly what he wanted. So with his grip tightening around Stiles's hips, Derek lost himself to the pleasure.

Stiles worked himself on Derek's cock, his fingers digging into Derek's shoulder. The sensation was overwhelming, and when Stiles leaned over, pressing a searing kiss to Derek's lips, Derek's knot began to swell.

"Oh fuck. Yes," Stiles moaned, his body shaking. "I need to come. Please. Fuck. Touch me. Make me come."

Derek pumped his hips, reaching between them to stroke Stiles's leaking cock, groaning as Stiles clenched tightly around him. And that was it. That was all it took before Derek's knot locked them together, his orgasm crashing over him.

Stiles threw his head back on a shout. The long column of his throat was beautiful as he cried out with pleasure, the warmth of his release spilling between them as his body convulsed in apparent pleasure. Derek's gums tingled, and as soon as his fangs dropped, he bit into the mark on Stiles's neck—claiming him once more.

Sweating and gasping for air, they rode out the waves of their orgasms together.

"We should...have s'mores...more often," Derek panted, the words slurred around his fangs.

Stiles laughed rather breathlessly, lowering his head onto Derek's chest as Derek raised an arm to hold him tightly.

"Very funny," Stiles mocked, though he sounded more pleased than annoyed. "Don't think we need s'mores in order to do this again."

Derek chuckled, idly stroking Stiles's hair with his other hand. No, they definitely didn't. Not with the affection they felt for each other and the unspoken desire that always seemed to hang heavy in the air. "Agreed."

"Also, now we're all sticky." Stiles chuckled, nuzzling into the crook of Derek's neck, a soft sigh slipping past his lips as his body relaxed atop Derek's. His heartbeat was a soothing metronome against Derek's chest. "Mmm…we should shower. When your knot goes down."

"Yeah," agreed Derek, gently running his hand up and down Stiles's back, the calm exhaustion an intimate comfort.

Stiles's breath evened out, and the steady rise and fall of his chest lulled Derek into a peaceful state, his fangs retracting. He wrapped his arm tighter around Stiles, losing himself in the feel of Stiles right there against him.
