Zoro's strap is too big.
Of course it is. Of course, because she always has to be the biggest and fastest and roughest in the room, and it's just not fair that Sanji lost the coin toss. She should be holding Zoro down by the back of her neck and plowing her with her own reasonably sized dildo right now. Not clenching her fists in the sheets, shaking, her breath knocked out of her chest as Zoro's cock pushes deeper and deeper inside.
The back of her neck is hot. This is so fucking embarrassing.
"Big, isn't it?" Nami asks. She touches her knuckle underneath Sanji's jaw and tilts her head upward to watch her take it. Sanji tries to school her expression into anything aside from blatantly overwhelmed. She attempts a smile.
"Nothing I can't handle, Nami dear." Nami brushes the pad of her thumb to Sanji's lower lip, and Sanji presses a kiss to it. "In fact, I've had bigger." She turns her head to sneer at Zoro over her shoulder. "Much bigger."
Zoro snorts. She spreads Sanji's cheeks to watch her cock bully its way into Sanji's stretched hole. The thing is green.
"What, like the size of your ego?"
"Fuck you, mold spore," Sanji snaps, and Zoro answers with a snap of her own hips that closes the distance between their bodies and makes Sanji gasp. She's overfull, her head aching with it, her cunt squeezing tight in protest at the abuse. Zoro sets a warm hand on Sanji's shoulder as she leans over her. Her voice lowers.
"You are fucking me, moron," she says. Her breath tickles Sanji's neck. A zip of electricity warms her belly. She works her jaw to hide it, but she knows Zoro's seen it. Nami's seen it, too. Nami lets out a satisfied hum as Zoro nips Sanji's ear.
"Just shut up and fuck me," Sanji says, eyes locked to where Nami's gorgeous hand is rubbing herself over her panties. They're a vivid orange nylon lace. The gusset is dark, soaked through from watching Zoro finger her open before.
"You're so god damn bossy," Zoro gripes. She pulls back slow enough for Sanji to feel every one of the dildo's raised veins just to shove inside again with one rough thrust. Sanji's jolted forward with the force of it, and a desperate noise escapes her throat as Zoro does it again, again, the slap of her hips meeting Sanji's ass filling the room, her cock hitting deep enough to ache.
"Y—" Sanji cuts herself off with a moan as Zoro starts to pick up the pace. It's all she can do to keep herself upright, and even then she's gradually getting pushed up the bed thrust by thrust until she's got one hand in the sheets and one on Nami's thigh, fingers flexed to keep from scratching her soft skin.
Nami's hand is inside her panties now. Her lips are parted as she watches them, watches Sanji's guts get shoved up into her ribcage, her eyes so wide and brown. Sanji whimpers at the sight.
"Open your mouth," Nami orders. So Sanji does.
And Nami withdraws her hand from her panties to press her fingers into Sanji's mouth. Sanji closes her lips around them with a cracked moan. The way Zoro fucks her from behind pushes Sanji onto Nami's fingers and forces them deeper, teases the back of Sanji's throat. She lavs the flat of her tongue over Nami's fingers, cleaning them of the divinity they've been dipped into, swallowing it down.
Nami spreads her fingers as she pulls out, stretching Sanji's lips, showing her teeth. She smears Sanji's own spit over her lips, her chin. Then she takes her fingers into her own mouth.
"N-Nami," Sanji moans, near sobs.
Zoro's thrusts stutter.
"Hey now," she tuts, "Nami's not the one fucking you."
Sanji groans.
"Piss off, Marimo," Sanji says, panting.
Zoro delivers a harsh slap to her ass cheek. Sanji jerks. She tightens around the hard silicone and pleasure bites into her insides.
"I'm fucking you. You say my name."
Sanji presses her lips together. She meets Nami's eyes.
Without turning her head, she grins.
"No," she says.
"No?"
"No. This was Nami's idea anyway."
Nami's gaze breaks with Sanji's for a split second, and then it returns. She bites her lower lip.
"Okay," Zoro says.
Zoro puts her hand between Sanji's shoulder blades and forces her chest to the bed. She gets a faceful of linen, smothered by the mattress, and before she gets the chance to complain Zoro picks up again. This time, the angle has changed so that Sanji feels her stupid cock in her throat.
"Hey," Nami scolds, "I wanna see her face."
So Zoro takes a fistful of Sanji's hair and wrenches her head back to let Nami see, but Sanji barely sees her, her eyes crossed and vision blurry. She claws at the sheets. She clenches her jaw to hold back the noises that punch at the insides of her teeth. This isn't fair. How is she supposed to live this down?
Zoro spanks her again. It shocks a yelp out of Sanji, which opens the door to all the other sounds she's trying to keep in.
"Who's fucking you?" Zoro asks. She spanks Sanji a third time. It's hard enough to leave her fingerprints in the muscle. Sanji squirms, but there's nowhere to go, Zoro behind and above and the bed below and Nami in front. Sanji's completely caged. Zoro spanks her again.
"Zoro!" She cries out. She twists her fists in the sheets. Zoro slows to a stop. She pets her hand down Sanji's flank. She massages the hot, tender flesh of her ass cheek.
"Good boy," Zoro tells her, low and taunting. A desperate moan comes from her chest, unbidden. She bites her lips closed a moment too late.
"Say it again," Zoro orders.
"Zoro," Sanji breathes, and is rewarded with Zoro pulling her back into her next thrust by her hair.
"Again."
"Zoro—"
"Again—"
"Zoro—fuck!— Zoro! Zoro, ZoroZoroZoroZoro—"
Sanji clings onto Nami, barely able to see well enough to watch her fuck herself with her fingers in time with Zoro, unable to hear the wet sound of her perfect cunt over her own helpless moans. God, she can't think, can't even breathe.
She can't come like this. Not untouched. Not if it's Zoro. She can't. She won't let herself.
"Oh, fuck, please, pleaseplease—" she begs, low in her throat, "please, oh, god, I'm gonna come I'mgonnacome—"
"You want her to?" Zoro asks.
"Fuck—yeah, I wanna see it," Nami gasps.
"You heard the lady," Zoro tells her. She bends down and wraps her arm around Sanji's waist, tits soft against Sanji's back, hand sneaking down between her legs. Her fingers slip, unable to find her clit in the wet mess. Her quiet laugh tickles Sanji's ear. "You're drenched," she says.
"Shut up, I don't want to fucking hear—"
"Yes you do," Zoro says, no less amused. "And so does your precious Nami." Zoro's hand shifts from her hair to underneath Sanji's jaw, gripping hard and forcing her head up. Nami's dazed, her cheeks flushed, her chest heaving, three fingers deep in her own pussy and grinding her hips against the heel of her palm. Her panties are a glistening ruin. Her slick is starting to soak the bed.
"Nami—" Sanji whimpers, and then her body tenses in anticipation of a strike that doesn't come. Zoro laughs at her.
"You train to easy," she says. Her fingers brush over Sanji's clit. Sanji takes in a sharp breath. Zoro pauses, hesitates, like she can't tell if the reaction came from what she said or what she did; so she does it again. Sanji gasps again, her knee pushing at the bed. Zoro makes a satisfied noise. "There it is." She starts rubbing tight little circles over the swollen nub, and Sanji squirms, curses grinding between her teeth. Zoro's thrusts are short and deep, keeping a nauseating pressure on her cervix, barely a step above humping. Sanji can't figure out if she wants to pull away or push closer. She can't do either of them anyways.
"Look at her." Zoro jostles Sanji's head to get her attention back on Nami. "She's close. All from watching you get fucked like a whore."
"Shit—" Sanji whines. She's there, right on the edge, teetering, so close—
"Sanji—" Nami moans, back arching off the bed, driving into herself harder and harder, her knees coming together to squeeze Sanji's shoulders, and that's it. Sanji's done for. She stares slack jawed as her entire body goes tight with euphoria, toes curling, legs shivering. She gasps as the wave passes, hiccups as the aftershocks begin to hit.
Nami strokes the backs of her fingers down Sanji's cheek. She's still breathing hard from her orgasm. Her eyes are glazed over as she looks down at Sanji.
"That was hot."
