Several hours have passed since Robin had begun her meticulous torture on the lovable, straining and throbbing fuck-toy in front of her. She licked her lips as she stared lovingly at the cum-covered cock, watching as it jumped and throbbed oh so desperately. Nami's heavy testicles pulled into her crotch from time to time, only to lose their strength and fall back into a lewd, hanging position. A glistening bead of precum leaked out of her aching tip; a small, yet delicious snack waiting to be devoured.

Robin could only guess how many times her slave had edged so far; the thought of that number having reached well above fifty was not an unreasonable one. Maybe it was even as high as a hundred? If nothing else, Robin was determined to keep going for much, much longer, regardless how high the number would get, before considering giving Nami even the slightest hint of relief. No, no relief would be giving until she was satisfied, and not even then would she stop; Robin was far too enthralled with her sadistic side to considering anything less.

Leaning in towards the massive phallus, Robin moaned like a whore in heat and enveloped her mouth around the tasty cock. Her tongue lapped all over it, licking and slurping her own cum off of Nami's throbbing length. She bobbed her head back and forth, fellating and stroking her meal with her eager mouth. Robin could hear the loud whimpering and groaning of her dear navigator, and she loved every second of it.

Robin raised her hand and cupped the bloated pair of testicles and squeezed them tightly, wringing out a desperate squeal from their owner. She pulled and tugged on them while keeping up the pace of her sucking, rotating her head and sliding her tongue along the underside of the shaft. Over and over she pushed the veiny cock down into her throat, relishing every single, burning inch of. Having already ejaculated once, Robin grabbed her cock with her free hand and stroked for dear life; She couldn't stand the infuriating throbbing between her legs any longer. Her testicles needed to unload.

Nami tugged and pulled on her bonds as if her life depended on it. No matter how you looked at it, this sensation she was experiencing was far too intense for any human to endure. Her teeth dug into the rubber ball in her mouth, not for the sake of chewing it to pieces, but to take the edge of the incredible pleasure being forced upon her. Her fruitless attempts at escaping, and the lewd, perverted moans and grunts were the only things her miniscule freedom would allow. Not a single, coherent thought existed in her brain, only pleasure and need.

Staring down at the archeologist, passed her big, heaving chest and rigid nipples, Nami could barely focus her vision to make out the details of the black, blurry blob sucking her cock. Not that she really cared about it, but surely it would be a lot easier to stay sane if she could see what was happening to her. A soon as her eyes focused on her cock though, even the slightest bit, the sensation escalated to an incredible height.

Seeing her own cock being milked so viciously and feeling at the same time made it far more sensitive and far more intense than it already was. Screaming out her muffled moans, Nami thrashed in her bonds as both her cock and balls pumped hard and fast; she was edging her brains out. Her heavily testicles pulled up into her groin with an incredible force as they readied up for a huge orgasm, or that's what they wanted to do at least. Robin had other plans, though, and kept pulling them back down and squeezed them tightly, teasing the plump balls as they repeatedly failed to unload.

Then something unexpected happened. Robin had reached up to the tight cock-ring and opened it ever so slightly, just barely allowing the boiling load inside Nami's balls to escape. Shuddering and shaking, unable to produce even the slightest sound, Nami braced herself for the incoming explosion as the massive, boiling load inside her testicles began to move. The strength of her ejaculation could be closely related to being punched in the balls, but in a more pleasurable and less harming way.

Instead of shooting out of her cock at an incredible speed, her thick, creamy load slowly pushed through her throbbing cock and leaked out of her pulsating tip. Nami could barely breathe as her explosive orgasm simply trickled out of her in the most frustrating way possible. Instead of filling Robin's mouth to the brim with cum, it just continued to drip out, slowly forming a tiny puddle on top of Robin's wriggling tongue. There was nothing that Nami could but to endure the seemingly endless, ruined orgasm.

Beneath her, Robin was happily sucking each cum-drop that escaped Nami's drooling tip. She couldn't even begin to imagine how frustrating it must feel to cum like that, it was so fucking hot to see her suffer such agonizing pleasure. Losing herself in her lust-drunk state, Robin popped Nami's cock out of her mouth and leaned backwards until her back rested against the floor. Pushing her hips into the air, Robin allowed Nami the perfect view of her own massive cock.

"Watch, Nami!" Robin moaned. "I'm going to cum again!"

"Mmmmph!!"

"Yes, yes! I'm cumming!"

Digging her toes into the floor and pushing even farther up in the air, Robin stroked her cock hard and fast until ropes of thick, boiling cum erupted from the tip. Her balls pulled into her groin and pumped for dear life, forcing more and more cum out of her. The hot, sticky sperm flew through the air and plastered all over her big, firm tits, her toned stomach and her entire face. Robin kept jerking her shaft, pumping all the tasty sperm out of her testicles that were bouncing lewdly up and down.

"Aaah! It feels so good to cum, Nami! It feels so good to squeeze all the semen out of my aching testicles!" Robin lewdly moaned as she entered a state of euphoric bliss. "Watch me cuuuum!"

Nami stared intently at her sadistic friend, watching as the thick ropes of cum exploded out of her. She whimpered and sobbed as envy and awe swelled up inside of her; she was the one that truly needed to cum... Yet there she was, forced to endure the slow, agonizing and harsh ruined orgasm while forced to watch Robin and her powerful ejaculation. With her cock still pumping and slowly oozing, Nami watched and moaned like the perverted and masochistic slave she was. Once Robin had finally wrung out the last drop of cum, she simply fell onto the floor and breathed heavily.

"That was wonderful..." She chuckled, playing with the sperm on her body. "Mmm, was a mess I made... I bet you would love to do that same." Her wicked gaze trailed up Nami's sweaty, tired body until it she stared her right in the eyes. "Do you want to cum like a proper person?"

"Mmm..." Nami softly replied, nodding slightly.

"I'll tell you what." Robin paused, summoning a couple of arms from the ceiling to hoist her up on her feet. "If you can keep yourself from fainting, I'll let your big, hard, throbbing, masochistic slave-cock spurt to your heart's content."

"..." Nami simply nodded before Robin could finish what she had to say. She didn't care anymore, she just needed to cum for real.

"Oh my, aren't we the eager one?" Robin seductively stepped in towards Nami, placing her friend's cock between her legs. "There's just one, tiny catch. I'm going to absolutely rape this bloated cock of yours until I'm completely satisfied, only then will I grant you the release you so desperately crave.

"Mmmm!" Nami groaned, her voice trembled slightly with both reluctance and eagerness.

"Should you faint before I get what I want, however, then I won't let you cum for an entire month..."

Without waiting another second, Robin slowly climbed up along the legs of the wooden cross and positioned herself just inches above Nami's throbbing cock. With a wicked grin across her face, Robin lowered herself and guided the massive length towards her wet, hungry cunt. At first she just teased the oozing tip by rubbing it between her drenched lips over and over. Robin ran her hand downward, along the length of the shaft, until she reached the ring and closed he tiny gap she had previously opened.

"Now, now, we can't have you spilling any more of that delicious sperm until you've earned a proper release, my beautiful, submissive pet." Robin chuckled, only inches away from Nami's face. Her hand lingered around the base of her slave's shaft, slowly reaching down and fondling her bloated sack one final time before wrapping both her arms around Nami. "Good luck..."

A second later, Robin fell down on Nami's cock with her entire weight, plunging the meaty member deep inside her tight cunt. Nami groaned and bit down on the gag in her mouth as she felt Robin's womb kissing the tip of her cock. The soft, yet firm and wet flesh tightened around her, squeezing the life out of her throbbing dick. She would've cum the instant Robin wrapped herself around her if it wasn't for that infernal cock-ring.

Having Nami finally inside of her, Robin lost herself in the moment as she savored the explicit details of the cock inside her pussy. From the smooth, slick tip, the girth and curvature of the veiny, thick shaft, to the intense heat emanating from her entire girlhood, there wasn't a single attribute of Nami's cock that wasn't completely perfect. Robin wished this sensation could last an eternity; to simply drown herself in this lustful heat and perverted desire would be like a dream come true.

With a soft, brief purr, Robin began to slide up along the cock until she reached the tip, then she squeezed it firmly and slowly slid back down. Over and over again, Robin meticulously teased her toy as much as she could without driving herself insane. It took a lot of willpower to not succumb to Nami's perfect dick, but Robin wasn't one to lose so easily. Slowly, over a long period of time, Robin increased the pace of her fucking until the room echoed of wet, sloppy sex.

Up and down, up and down, rhythmically and raw she fucked, faster and harder as the minutes trickled by. Robin couldn't help it; her sadistic nature was in full bloom she absolutely loved watching her dear slave in so much painful pleasure. Robin could feel the throbbing, edging monster of a cock inside of her; she wouldn't allow it a mere moments rest. Nami's expression was a mix of sexual bliss and exhaustion, and it served as a wonderful source of motivation for Robin to push her tortured pet to even greater heights of frustration and aching desperation.

The room was thick with the smell and sound of lewd, wet sex, and hadn't the room been made soundproof, the people walking around outside would surely come and check what all the screaming and moaning was all about. Robin surely wouldn't mind having an audience, though; the thought of being watched by her friends was always gnawing on her mind, It was a dangerous thought; Robin had no way of telling how they would react to seeing them fuck like bunnies. It could completely ruin their relationship, especially since they were all confined on a relatively small space. But the potential would always linger in her mind, nudging her onward to taking that risk and maybe even turning it around and elevate their already amazing sex into something out of this world.

Even though Robin was lost in her own world, her efforts in fucking the brains out of the navigator wasn't lowered in the slightest, quite the opposite in fact. As Robin's fantasies swept her away, her lust and needs increased until she was impaling herself on Nami's cock as hard as she could. Over and over she slammed herself into Nami, pushing herself closer and closer to the edge. The wooden cross that her slave was bound to was very sturdy and well-built, but, even so, the wood creaked and groaned under Robin's sexual assault.

Not even Robin could keep herself from squealing like a whore at this point; every single thrust caused her to almost scream out her moans. Nami's big, throbbing cock pushed her tight, wet walls aside with ease as she bounced up and down on it. It was just too fucking good. Each time it slid inside of her, Robin was being pulled hard towards her third orgasm. And, surely, after just a couple of more thrusts, the archeologist was forced over the edge.

Robin swung her head backward and pushed Nami's cock as deep as she could while she came. Her pussy throbbed and squeezed the tasty length, cumming all around it. Nami's eyes began to roll into the back of her head as Robin's cumming pussy tightened around her sore, edging cock. It took everything she had not to faint on the spot due the overwhelming sensation and fatigue she was experiencing; even so, she loved every single second of it.

"Oh my..." Robin sighed. "That was amazing."

"..." Nami didn't respond, she was far too busy groaning, trembling and shaking from the onslaught of continuous edges forced upon her by Robin's tight sex.

Robin licked her lips and watched as Nami desperately tried to keep herself awake; it was a gorgeous and erotic sight to behold. She wasn't done yet, though. Raising herself and letting the big cock slide of out her, Robin leaned in just and tiny bit and grabbed Nami's pulsating member. Being far too eager, Robin no longer cared about teasing her masochistic friend. No, that part would come naturally. Robin guided the cock towards her ass and simply lowered herself right on it.

Nami couldn't even produce a single sound at this point, she could only gasp for air and keep herself conscious while Robin continued to rock her world. The pleasure was indescribable, she had never been pushed this far before and she was having problems coping with the heavy stress her body was being forced through. All her muscles felt like they were on fire and her cock and testicles strained and pulsated as if mere moments away from rupturing in a huge, sticky explosion.

The navigator wasn't the only one having difficulties; Robin was drunk on cock and couldn't stop herself from fucking Nami to the very limits of her ability. She bounced up and down, fast and hard, without a single thing on her mind except for the delicious cock filling her ass. Even she, who usually was so refined and collected, had lost her mind completely and was acting like some common, perverted whore. She didn't care, though, as long as she got what she wanted, nothing else mattered.

"Yes, yes, yes!" Robin moaned. "Your cock feels so good inside me!"

Pounding her toy with all her might, Robin felt the pleasure boiling inside of her, slowly rising towards that familiar edge. Her heavy, firm tits bounced and rubbed against Nami's, and her cock strained and ached between them. She was getting closer for every second that passed. Up and down she bounced, staring her friend in the eyes, grinning and moaning without restraint. As she felt herself unable to hold back any longer, she reached down to the ring and readied herself.

"Are you still there, Nami?" Robin asked, not slowing down in the slightest. "Does the little masochistic slut want to cum?"

"MMMM!!" Nami screamed with the last of her energy, leaving her fate in the hands of her cruel mistress.

"Ah, ah, aaaah! Then cum to your heart's content, you delicious fuck-toy!" Robin quickly brought herself to her fourth orgasm and quickly undid the thick cock-ring around Nami's shaft.

Nami's eyes shot open and rolled to back of her head the very second her balls tensed up. Her teeth dug hard into the rubber ball-gag in her mouth and puncturing it completely. Her muscles tensed up and her limbs pulled at the bonds keeping her in place. Her cock expanded rapidly, pushing Robin's walls apart. In a single, strong pump, her testicles pulled into her groin and all of her semen rushed through her throbbing member and exploded out of the bloated cock-head. Nami gasped for air, inhaling as much oxygen as she could and braced herself.

Robin felt the expansion in her ass and pushed the cock in as far as she could while her pussy and cock erupted with pleasure. A single moment later, gritted her teeth and groaned; her eyes shot open and her ass was filled by a flood of cum. The thick, sticky and boiling stream of cum reached far into her intestines, clinging to every inch of her fleshy wall. More and more poured into her, like a garden-hose that someone forgot to turn off.

Even as a whole minute had passed, Nami was cumming just as hard as the first few seconds of her orgasm. Her balls were pumping in and out of her groin, desperate to unload every single drop that had been churning inside of them up to this point. Her cock was pulsating and throbbing with every single thick stream of semen that was released. The pleasure crackled through her body, up her spine and out to her toes, almost as if she was being electrocuted. Finally, a couple of seconds later, Nami could no longer withstand the sheer force of her release and her head simply slumped over.

Robin moaned and sighed as her orgasm was finally allowed to dissipate; Nami's intense and violent ejaculation had also trapped her mistress in a minute-long, hellish state of continuous orgasming. As her sanity and sentient thoughts return, Robin just smiled triumphantly as she leaned in and kissed the sleeping navigator. And, just to make sure, Robin checked that the poor thing still had a pulse and that she was still breathing; which she thankfully did.

"Thank you for the meal." Robin chuckled, rubbing her slightly bulging stomach.
