It was late at night and the Strawhats had merrily fallen asleep to the calm waves and the gentle breeze. It had been a wonderful day, full of crazy things and weird-looking sea creatures. The sounds of snoring could be heard from every direction, except for one. It wouldn't take a genius to figure out which room was void of the incessant noise of several hibernating and/or comatose monkeys. Compared to the male quarters, Nami's and Robin's room had far more enticing and active things going on.

Every night, just after the crew had gone to sleep, Nami and Robin would entertain themselves with some rather carnal desires. Both of them would spend their days in wait of the approaching night without anyone knowing how eager they were for it. The last few hours of the day was like pure torture for the two. Their impatient nature often had them fooling around most of the time, just barely hidden from any watchful eyes. Once nighttime arrived however, these females would drop all restraints enforced upon them, by themselves, and engage in the most lustful, wild sex you could imagine.

Nami and Robin were actually quite lucky that Franky had been so kind to soundproof their room to "prevent Luffy from disturbing Nami when she was working on her maps". If he hadn't, then the rest of the crew would have to deal with the nightly screams of lewd ecstasy and the loud cries of pleasure. Having Sanji risk death by blood loss every night wasn't really much of an option for them. Despite that, Nami did actually get a few nice and quiet moments for when she worked, thanks to the new walls, but that wouldn't stop the two from also using the room as a breeding ground.

Tonight was no different and the frustration had built up quite substantially within them. Unlike other nights however, where they just fucked each other's brain out, Robin wanted to try something a little bit different. This time, Robin wanted to pleasure Nami using only her mouth. Nami was not allowed to interfere in any way and would have her own hands behind her back. Robin had the habit of prolonging her blowjobs to the point where it drove her lover wild with frustration, much to her own enjoyment of course.

"Oh fuck, Robin... That feels so good!" Nami moaned.

Nami was standing in the middle of the room, completely naked, with Robin's hungry mouth wrapped around her stiff member. The slick tongue twirled around the tip of her sensitive member, teasing her slightly as the mouth continued to take it deeper. She groaned softly as the suction around her throbbing cock increased by each passing moment. Her hands were still behind her back, but it took almost everything she had just to keep them in check.

Ever since they started, Robin had been very meticulous in the amount of pleasure she was giving Nami. She really wanted to perfect her technique, so it would be quite counterproductive to have her ejaculate too soon. Her tongue rubbed lightly against the underside of Nami's dick as Robin bobbed her head up and down in a rhythmical motion; she spread her own legs and allowed her own cock to spring out from between them.

She couldn't help but moan as she continued to suck, slurping and tasting her lover to the extent of her ability. Robin was so incredibly horny and her cock was aching and throbbing so hard that the precum just wouldn't stop dripping from her tip. It was an incredible feeling having your erection jumping out of sheer frustration, desperate for the slightest bit of attention. Robin arched her chest forward and pressed them together with her arms. The palms of her hands were resting against the floor with just enough space for her cock to poke out between her arms.

Nami looked down at Robin, watching as the woman jiggled her ass and breasts as she continued to slurp on her dick. Her face was so lewd, mouth wrapped around Nami's cock and her lips dragging across the length of the shaft. She felt her testicles pulled up into her groin as the pressure slowly increased. Nami exhaled and groaned as Robin began kissing the tip, leaving the rest of her member begging for more.

"Stop teasing me so much, Robin..." Nami groaned.

"Then it wouldn't be practice, now would it?" Robin grinned briefly before opening her mouth as wide as she could and sticking her tongue out so she could lick the pulsating shaft in front of her.

"B-But you've been at it for at least an hour already..."

"It's only been twenty four minutes, Nami."

"Whatever, I'll go insane before you're done!"

"And?" Robin looked up at Nami and chuckled softly.

Robin lowered herself slightly, running her tongue down Nami's shaft until she reached her balls. Without waiting, Robin sucked the testicles into her mouth and began juggling them. It was pretty hard to make them bounce around considering their size, but that wasn't going to stop her from at least trying. With those large, heavy testicles filling her mouth, Robin moaned and pressed against Nami's frustrated cock, rubbing her forehead all over it. She kept looking up at Nami, but that didn't work too well as her pulsating member and her large tits were in the way.

"Oh god... That feels too good! My balls are bursting with cum... Please, Robin, milk my cock dry!"

"Mmmm!"

Nami's pleading was just what Robin wanted to hear; making her lover beg for release made her so incredibly aroused. The skin around her cock felt unbelievably tight and she could just imagine how good it must feel to fuck Nami's pussy right now. Precum kept drooling out of her excitement as she fondled the balls inside her mouth. Robin lowered her head further, pulling and stretching Nami's testicles. "I can't wait to taste her thick, sticky semen..." she thought.

With an audible *pop*, Robin released Nami's balls and watched as they quickly pulled up into her groin. She could see how the navigator's legs trembled from the strain of having to endure Robin's blowjob while standing up. It was as if she was trying to stop herself from fucking the air with her frustration cock. It was quite adorable actually, but that wouldn't be enough for her to show Nami some mercy. No, the night was still young and they were far done.

Nami groaned as her balls contracted into her body, aching and throbbing violently with desire. It was so infuriatingly hard to control herself and stay still while Robin worked on her cock. Her face was bright red and her breaths were getting faster and more rugged. She could feel how the slick, wet tongue of the archeologist pressed against the underside of her stiffness, slowly running up her hot length. Every time she reached the tip, Robin would take it in her mouth and suck and flick her tongue up and down the slit of her cock.

"Fuck! Stop teasing me so much and suck it like the slut you are!" Nami let out a frustrated groan as she finally snapped from the intense teasing.

"Mmmmph!?"

Nami grabbed Robin by her head and forcefully rammed her cock straight into her throat and began thrusting in and out. She moaned happily as she fucked her lover's face as hard as she could. Her fingers wrapped around the hair and dug into the back of Robin's skull, guiding it back and forth. "Fuck, yes!" Nami gasped, "Suck that fucking cock, you whore!" Wet, sloppy sounds of throatfucking echoed inside the room, mixing pleasantly with Nami's slutty moans and Robin's quick, desperate gasps for air.

Robin hadn't been completely taken by surprise by Nami's sudden aggression; this was what she had been working for all along. The moment where a person loses all hints of control and restraints, to have them drown in a perverted desire got Robin off something fierce. She had done these kinds of things before she had joined the Strawhats, but those moments paled in comparison to the joy she felt from teasing and playing with the girl currently fucking her throat.

Nami kept thrusting in an out of Robin, over and over again. Her testicles slammed into her lover's chin with every push she made, sending jolts of pleasure throughout her entire body. They felt so incredibly bloated and full, ready to burst any second now. She looked down at Robin, watching as her cock slid in and out of her. Nami loved how lewd the archeologist sounded as she gagged on her massive, throbbing limb.

"Oh yes... choke on my fucking cock, Robin!" Nami groaned. "This is what you get for messing with me!"

Robin was in heaven; her throat was being fucked like some kind of inanimate object, used purely for pleasure and satisfaction. She slurped and sucked as best she could as it cock slid in and out of her throat. Her own cock jumped and twitched with excitement from the intense pleasure of being used by Nami. Robin was so horny and excited that her dick began to edge as Nami continued. It was so hard to breath with that monster ravaging her throat that her eyes started tearing up.

Her cock was on fire, burning from the frustration of not being touched and it was all made even worse as it kept edging and edging. Robin dug her nails into the wooden floor, determined to keep her hands off of her throbbing member. Her testicles pumped furiously, desperate to release the boiling load trapped inside of them. Nami's grip around her head tightened as she pounded her mouth, pulling and pushing, back and forth. She was about to cum any second now.

Once she realized how close Nami was, Robin closed her eyes and used her powers to fill her mouth and throat with as many tongues as she could. They coiled and wrapped around the invading member, licking and rubbing all over it. This was far more than what Nami could handle. She gritted her teeth as her balls contracted and began pumping. Nami's entire body tensed up and with her last remaining strength she pressed Robin's face against her groin.

"I'm cumming!" Nami gasped.

Robin managed to take a final breath of air before her throat was completely plugged up by Nami's pulsating member. She was actually quite lucky, just a second later and her lunges would have taken the brunt of Nami's ejaculation, and ejaculate she did. Hot, thick strings of semen burst out of her, plastering the walls of Robin's throat and shot straight down into her stomach. If anyone was watching, they would be able to see the bulge on the outside of Robin's throat, pulsating as it emptied its load inside of her.

Tears streamed out of Robin's eyes and ran down her face as she gagged on the ejaculated cock. Her tongues rubbed up and down on Nami's length, stroking and licking as she came. One of her tongues pressed itself against her slit and lapped all over it, tasting her delicious cum as it exploded out of her tip. She could feel her own member ache with need, screaming for the tiniest bit of much needed attention.

Robin quickly raised her hands off of the floor and flung them around Nami's hips and grabbed onto her butt cheeks. It wasn't because she wanted some ass, even though it was like a nice bonus, it was to keep her hands from stroking her own cock. Robin was a bit of a masochist and loved to edge; the feeling she got in her testicles and dick was amazing. Keeping her cock on the verge of cumming and denying any approaching orgasm was intense and very satisfying.

"Oh fuck, I can't stop cumming!" Nami whimpered.

As those words echoed inside of Robin's mind, her body finally betrayed her and nudged her aching cock over the edge. Rope after rope of boiling cum shot out of Robin's pumping penis; it flew between Nami's legs and splattered against the floor behind her, creating quite the mess. She gagged and moaned, sending tingling vibrations all over Nami's throbbing erection. Both girls were shaking and trembling as their orgasms continued.

It took the two roughly thirty seconds to empty their sacks and to finally stop cumming. But even as the final drops of semen slowly trickled out of their twitching cocks, Robin's tongues were still licking and rubbing all over Nami's sensitive length. Tirelessly they coiled and wrapped around it, twisting and rotating without an end in sight. Robin, who still had her arms around Nami, didn't want to let go of the tasty treat inside her throat; unless she wanted to choke on the thing, she would have to force herself to give it up.

Thankfully for her, Nami's grip on her head had loosened up after the hard orgasm and allowed Robin to pull away. Inch after inch, Robin slowly removed the pulsating shaft until only the head was left inside her mouth. She took a deep breath through her nose and slurped strongly all over Nami's sensitive tip. The navigator whimpered and moaned as Robin gave her cock a final kiss before letting her go.

"Mmmm..." Robin licked her lips and swallowed any remaining cum left inside her mouth. "I thought we agreed that using our hands was considered cheating." She chuckled lightly, not caring about the rules in the slightest.

"You can't expect me to survive for that long inside your mouth, Robin?" Nami smiled back, feeling much better after releasing her pent up frustration. "

"Fufufu, I guess you've got a point. At this pace, however, we will never improve as much as I would've liked. I believe I have to tie you down next time we do it..."

"Like I'd let you do that! I know how much you love sucking cock, Robin. You wouldn't let me go until next sunrise!"

"What if I give you something in return?" Robin leaned back, presenting her erect cock to Nami and began humping the air, letting it bounce lewdly up and down. "If you let me have my way with you, you can do whatever you want with me. Doesn't that sound fair to you?"

"..." Nami stared silently at the bouncing cock and swallowed, it was a really tempting offer after all. "A-anything?"

"A.n.y.t.h.i.n.g..." Robid lewdly replied.

Nami just stood there, enjoying the show Robin was giving her and contemplated accepting her offer. But something felt really off, it was like she was signing a contract with the devil. Regardless, she would be able to do whatever she wanted with Robin and she wouldn't be able to reject her. Her head was filled with images and ideas of perverted activities. There was so many different things that she wanted to try, but Robin was such a slut that she'd end up doing them anyway. No, she needed something that would rival what Robin was going to do to her, if not something that was even worse.

That's when it dawned on her, something that would have Robin screaming and whimpering for hours on end; something that would be considered pure torture for her. Nami held back the widest grin of her life as her cock strained with arousal. Yes, she knew exactly what to do, but first she had to endure and survive a night trapped inside Robin's mouth. But regardless, that was a small price to pay to be able to absolutely destroy that perverted archeologist and make her think twice about giving Nami such an opportunity again.

"Sure." Nami's poker face was flawless, hiding her excitement from Robin. "It's a deal."

"Wonderful..." Robin replied. She had no intention whatsoever of hiding her own excitement and grinned widely. "We start tomorrow and I will be going first, just letting you know. Make sure you prepare yourself because I'm not going to show you the same mercy I did today..."

"Bring it on!" Nami's eyes burned with determination as the two shuck hands. "And until then?"

"We fuck like bunnies of course..."

"I like the sound of that... I can't wait to ram my cock into your pussy, Robin..." Nami replied, stroking her drooling cock.

The two girls made their way over to their beds and jumped in. For the rest of the night, around three hours, they fucked, licked and sucked as much cock and pussy as they could, covering their sheets with all the juices they could produce. Robin and Nami would normally show a bit more restraint and avoid covering everything with their spunk but tomorrow was Sanji's turn to do laundry and why not tease the poor chef a little by leaving a nice, messy little gift for him to find? They would have to give him the sheets personally and make sure he knew it was from them. They really loved knowing how horny he was and how much he lusted for them, so why not make him ache just a tiny bit more?
