Zoro's eyelids were fluttering, almost asleep after a mere three minutes of post-coital cuddling.
Sanji observed his lover from where he had his chin propped up on the swordsman's chest, an eyebrow raised in bemusement. The man was truly hopeless. Wasn't this the moment for heartfelt declarations of love, soft kisses and appreciative touches? Though the touches were there, he supposed. Zoro's strong arms were curled around the blond, one hand on the small of his back and one playing with the soft hairs on his nape. Their legs were tangled together under the sheets. Sanji felt himself sinking further into his lover's warm touch, basking in the fact that he was allowed this close to a man like him.
Breathing in Zoro's scent, Sanji wandered if this was a good timing to bring it up.
That little urge that had been teasing him, slowly intruding on his dreams, filling him with curiosity. Left alone on that cross, hearing heavy footsteps behind him. For a moment worrying Black Maria was back, but sighing in relief as familiar, calloused hands came around to cover his eyes. "Don't be scared, cook. I'm not gonna do anything bad."
"Hey moss?" Responding to the insult that was more of a pet name these days, Zoro grunted beneath him. "There's something I wanna try next time, if you're up for it."
"Hnh?" Eloquent as always.
"So, uh..." Now that he was actually trying to say it out loud, he couldn't seem to get the words out. "I, uh. I was thinking..."
Picking up on his nervousness, Zoro cracked open his eye. He tried to catch Sanji's gaze with his own, but the cook ended up turning his eyes down, focusing on Zoro's scar as he felt his own face flush slightly.
"What's up, cook? You 'bout to suggest something really kinky or what?"
"No, idiot! Just let me think about how to phrase it, okay?!" Sanji propped himself up on his elbows specifically to glare at the mosshead, the arms around him relaxing slightly to let him get up. Zoro looked at him, unimpressed.
"Just so you know, if it's got something to do with piss, I'm out."
"I just said it wasn't anything super kinky! What the hell are you thinking about me, you damn brute?!"
"Hey, not kinkshaming or anything, I'm just not into that."
"It's not piss, you shitty..." Sanji sighed, and lowered himself down to bury his face in Zoro's chest. "Iwannabetiedupmaybe."
"Huh?" Zoro's voice floated above him as he pressed his burning cheeks into the swordsman's skin. "Can't hear you when you whisper like that, cook."
Sanji grumbled, but angled his face upwards a bit.
"I want to try doing it while I'm tied up. Wanna try giving up control." To you. "Maybe with a blindfold and a gag as well, not sure about those though."
He could hear Zoro humming as he thought it over. Given the physical reaction going on underneath him though, it seemed he wasn't completely opposed.
"Yeah, let's try it," the swordsman finally said. Sanji felt his heart skip a beat in excitement. "Let's skip the gag for the first time though. Wanna be sure I can hear your safeword if you need it."
"You worried you're gonna break me, mossy?" Sanji smirked as he drew closer to his lover's face. Zoro frowned.
"I'm not, I just..."
"I know, mossy. Was just joking around." His smirk morphed into a fond smile as he leaned in for a kiss. "It's a date then."

Sanji tugged experimentally on the soft rope binding his arms out to the sides, pleased to find them with just enough give for him to squirm, but not really being able to move. It had taken some research, but they'd been able to find a way for his arms to be restrained away from his body without putting to much pressure on his wrists and hands. It had taken even more time before Zoro was able to actually recreate the bindings they'd found in that book. Sanji had begun to despair, but as he finally stood there, naked and tied up, it was definitely worth it.
"Doesn't pinch anywhere, curly?" Zoro was flitting about around him, uncharacteristically jumpy.
"I'm good, Zoro, I promise. What about you? Sure you want to try this?"
Zoro paused, clearly not anticipating the question in his direction. He closed his eyes and took a few deep breaths, tension slowly seeping away from his shoulders.
"I do. Just don't wanna hurt you." He flushed slightly, very much not looking like a man ready to conquer and devour. Sanji smiled fondly at him.
"Though you said you weren't worried about breaking me? Seriously though, it's getting cold here, so if you're still into it, let's go already."
Zoro nodded and removed the bandana from it's usual place around his bicep. He stepped in closer and caught Sanji's eyes with his own.
"One last time, Sanji. Do you want this?"
"Yes."
"Repeat your safeword for me."
"Sauté."
"Good." Zoro leaned forward to kiss his forehead. "I love you."
"Love you too."
As the bandana covered Sanji's eyes, he felt his other senses working to deal with the loss. Zoro's hands passed through his hair after tying the makeshift blindfold, and he couldn't help but shiver.
Then he was left standing there, completely alone. Faintly, he could hear Zoro pacing around the room as several minutes passed. His own breath seemed to increase in volume in his ears as excitement spread through his body. The sound of fabric falling to the ground somewhere behind him felt ten times louder than it should've. He's getting ready for me. Sanji's cock twitched.
"When you're like this, it would be so easy to cut you."
A touch of something cold to his waist made him yelp loudly. A deep chuckle in his ear followed.
"Don't worry, cook. It's just the scabbard." A sword, he's touching me with one of his swords. Sanji gulped. It wasn't enough.
"Please... use the actual sword." Zoro would never cut me, it doesn't matter how easy it would be. "I wanna feel it."
His heart beat in his chest as Zoro though about it. He could hear him breathing, feel the air passing out of his lungs and onto Sanji's burning skin. The scabbard left his side and was put to the ground with a thud.
"No. Maybe if you're very good, I'll let you feel it next time." A pair of strong hands wrapped around his hips, pulling them backwards until he was pressed against Zoro. Sanji whined.
"I promise, I'll be so so good. Please let me be good for you."
Zoro started pressing kisses to his neck as his hands roamed around the front of Sanji's body. He moaned as Zoro started grinding against his backside, kisses turning into bites. Sanji felt a bead of precum drizzle down his shaft, still untouched.
"Zoro, I want - ah!" His demand was stopped as Zoro started massaging one of his nipples. A wet tongue passed from the crook of his neck up to his jawline. "I..."
"What, cook? Can't focus?" Zoro laughed as he started grinding more vigorously. Sanji's frustration grew until he couldn't keep the instinctive insults back.
"F-fuck you, shitty plant, just - huh?" Abruptly, Zoro stopped moving completely, still holding him steady but doing nothing more to escalate. "Keep moving, fucker, why would you-"
"Show me, Sanji. You said you'd be good, right? Show me how good you can be."
Sanji whined, squirming in his grip. Shitty moss, he'd show him alright. He turned his head around as much as he could, grasping with his teeth until he found skin. Zoro hissed as Sanji started nibbling on his jawbone, continuously switching between licking and tugging. He used his calf muscles to grind up and down against Zoro's dick as thoroughly as he could, panting as he felt precum making the slide easier with each thrust. Zoro's hands gradually went from simply holding his hips to grabbing them tightly, digging his nails into pale skin.
Sanji knew he had succeeded when Zoro growled, letting him go completely and stomping over to another part of the room. Dumbass left the lube on the shelf. The blond used the few moments of respite to focus on breathing. He had a feeling things were about to get intense.
Instead of returning to his former position, Sanji felt Zoro's presence in front of him this time. He could feel himself being observed. The feeling of being inspected without being able to return the favor was doing something to him, a keen ripping itself free from his throat. No sooner had it left than Zoro pressed close to him, swallowing it with a deep kiss. Sanji felt oddly emotional as they broke the kiss.
"Zoro, please..."
"I'm right here, Sanji, I'm not leaving, I promise."
The swordsman used one arm to press his lover even closer as the other traveled down to start opening him up. Sanji gasped as Zoro used firm, precise movements to stretch him open, not letting the blond move an inch in his iron grip.
"Zoro, Zoro, I'm - I need - Zoro-"
"It's alright, sweetheart, I've got you. Can you hold onto me with your legs, baby?"
Sanji nodded, following willingly when Zoro grabbed his thighs and started carefully guiding them to wrap around his waist. The swordsman used his own body to balance the other man, making sure that his bound arms didn't have to carry his weight. As Sanji interlocked his ankles, he felt Zoro's hands moving from his thighs to grab at his ass, spreading his cheeks wide.
Sanji was overwhelmed. His arms shook against their bonds as they instinctively wanted to circle the swordsman's neck. He could feel the swordsman's hot breath, but he couldn't see his eyes, couldn't hold him properly, couldn't -
His spiralling thoughts were stopped as blunt pressure started making his way into him, Zoro growling as he pressed further. Sanji struggled to keep breathing, he was used to the feeling of the swordsman inside him, but coupled with the loss of vision and movement it was just. So much. Too much. He sobbed as Zoro bottomed out inside him, filling him so perfectly. Zoro nuzzled against him, silently waiting for permission to continue. Sanji pressed his face into the crook of Zoro's neck, breathing him in, listening to the sound of his blood racing through his veins.
When the sensations turned from being overwhelming to feeling like so much but still not enough, he raised his head to kiss Zoro's cheek in a signal to continue - though from the feeling it seemed like he landed somewhere closer to his eyebrow. Zoro still understood.
He wasted no time and started moving fast and hard from the start. Sanji had the brief thought that his lover must've enjoyed this situation very much indeed before his thoughts were completely wiped to make room for pleasure. Gasps turned to whimpers turned to screams as Zoro thrusted upwards into him, using his strength to pull and push at him as much as the ropes would allow.
Sanji's blindfold was wet, he didn't know when he had started crying but now he couldn't stop. Zoro's grunts in his ear, the rumbling in his chest, the way he filled him so deep, so well, like they were made to fit together, like he was made to live like this. Something was bubbling inside him.
"Ple- Zoro I- I ca-"
"Do it, cum for me, you've been so good Sanji-"
Sanji felt himself slump into Zoro's arms as he came, feeling Zoro's thrusts slowing down as he rode out his own climax. Through heavy breaths, Zoro held onto him tightly, rubbing one arm soothingly over his back.
"I'm going to remove your blindfold now, yeah? Keep your eyes closed so it doesn't get too bright."
Sanji hummed approvingly as the piece of fabric slid down to the floor. In the back of his mind he registered Zoro making frustrated grunts, trying to open his eyes to find out what was going on but finding his eyelids too heavy. It's all fine, he's got me. When sleep came for him, he didn't resist.

Sanji woke to warm fingers massaging his scalp and a scarred chest against his back.
"Hey, mossy," he croaked, immediately starting to cough. A glass was pressed into his hand.
"Drink some water, cook. The snacks you made before are here too when you're ready."
He hummed, handing the glass back to Zoro when he'd soothed his sore throat. Zoro gently grasped his chin and guided him up into a chaste kiss. Sanji wanted to drown in the love he could see in that one grey eye.
"Thanks for indulging me, moss. I liked it."
"Me too. Are your shoulders okay?"
"I think so, won't know for sure until I get the energy to move though."
"Next time we're gonna have to bring a chair or a barstool or whatever for me to put you on, getting you down was a bitch."
"There's gonna be a next time then?"
"Hell yeah. Didn't know you were into knifeplay, but we can get that in there since you like it so much."
"Shut up, shitty moss. Actually, now that you mentioned it, how did you cut me down?"
"Feet."
"Feet?!"
