Author's Note: This is a prequel of sorts. It covers Bob's history and background. After the first few chapters, time starts whizzing by, as decades were covered. I recommend reading the first three Challenge stories as there are Easter Eggs, character cameos, and call backs to them in this story. The characters of Tiffanie and Diane will each have two stories -- the first being an interracial one, the second being incest. Keep a lookout for those as Diane's first story as it may be published by the time this one is -- it'll be under the Former Playboy Playmates series on my story listings page.

The Challenge 4: Origins and Revelations
Chapter 1
He was going to take her. After weeks of watching her, studying her, memorizing her daily routine, Robby was going to hunt her down and take her. He didn't want to do it, deep down, but his animal urges of being stranded with her, had become too much to resist. He hated the island, he hated how long they've been stuck there, he hated himself for even entertaining the idea of doing what he was about to do.
Robby watched her undress from his vantage point behind a cluster of palm trees. It was a full moon. The pale light was bouncing off her sweaty skin. She placed what was left of her clothing in a small pile. They were all but tattered rags now, her panties full of holes, her top shredded by a knife to use scraps of it as strings and ties. Robby watched her slowly enter the small pool of water at the base of a small waterfall.
He chastised himself for being turned on; he hated himself when he'd watch her work on the beach during the day, her tanned skin accentuating her musculature that was now visible due to massive weight loss. He would stare at the underside of her breasts and bare tummy while she carried coconuts. He would watch her hips sway when she surfaced from the ocean water with a fresh haul of clams, her light-brown hair slicked back, remnants of her shirt sticking to her skin. After weeks, Robby watched her, each day bringing him closer to taking her.
Masturbation only worked for so long. Robby would sneak off away from camp at night, jerking his cock behind a tree, or in the same pool area he just now watched her wade into. He felt more shame for cumming to thoughts of her. Over time, that shame faded, the desire for a real pussy milking his shaft instead of a hand coming to the forefront of his mind.
Robby's desires multiplied tenfold when he caught her pleasuring herself one night. She had wandered off from camp and was gone for quite a while. There were no animals on the island that could hunt, kill, and eat a human but Robby thought there might be snakes or, in his most paranoid thoughts, a rat could bite her and infection could follow. He didn't know for sure. He was concerned and told Cori he'd be back in a little bit.
Robby stopped dead in his tracks when he saw her, naked, in the pool, the small waterfall behind her, furiously rubbing her clit, moaning into the night. She was beautiful. Robby nearly came in his own tattered shorts, when he watched her turn around, thrust her hips forward, allowing the surging water to crash down on her pussy. It was nature's own high-powered shower nozzle. He watched her shake and buck her hips, while holding on to vines on each side of the waterfall as the flowing water lapped at her pussy, causing her to scream out in orgasmic bliss, becoming one with nature.
The instant his hand grabbed his throbbing bulge, he ejaculated. After seeing that beautiful display, he started watching, planning and deciding when to take her. Robby considered the risks, thinking that maybe she'd understand given their situation on the island.
Watching her bathe, running the water through her hair, over her medium-sized breasts, and over her hips, he began getting aroused. Robby watched her turn to the waterfall, her lover, and smile, extending her hand to it, considering on making love to it once more. So many nights on their three months on the island, the flowing water of that little waterfall, unknowingly brought her so many orgasms. Tonight though, she decided not to treat it to her body. Slinking out of the water, as clean as a soap-free bath could get a person, he made his move.
It was his 18th birthday and this would be his present to himself.

Robby looked back toward camp and then around him to make sure Cori wasn't near. He pulled off his tattered shirt and shorts and rushed to her, grabbing her tightly from behind, and as gently as possible guided her to the sandy ground.
She cried out, startled by him, "Robby!"
The side of her face in the sand, she tried pushing herself up and him off her, but he was too strong. He flipped her over on her back, "Robby! What are you doing?!?" Her were arms flailing, attempting to push him away, his face wrought with hunger and desperation.
As soon as she figured out what he was doing, feeling a hard cock against her tummy, as he struggled to move downward to enter her, she relaxed slightly. "Robby, no. No. Don't do this," she pleaded in a stern manner, her legs attempting to push him off at his hips.
"Robby, no!" She said again sternly. Robby managed to push her legs apart and slam himself down. "Robby, you don't need to do this," she said, almost calmly.
His head was resting on her shoulder, his hips thrusting away, trying to find a way in to her, "Robby please."
She was struggling, moving from side to side, her legs unable to push his weight off her. Robby found his way in; finally, he pushed in all the way, listening to her groan. "No!" she cried out.
Robby pinned her hands down, and was thrusting away manically with no order or pattern. He peered into her eyes, his own eyes apologizing for doing this, for taking her. She looked at his eyes, her face wincing from discomfort, her eyes not showing anger but sadness and empathy.
When it was done, Robby filled her with semen, collapsing on top of her. They began crying. He was crying because they were still stuck on the island with no idea of when, or if, rescue would arrive. He was also crying because of the overwhelming guilt that now flooded him.
"I'm sorry, I'm so sorry," He pleaded in between sobs.
She sniffed, her body relaxing, her hands running through his blonde hair. "Shhh, it's ok," she sighed. She let him do this; she could've resisted more, but chose to allow it to happen.
Robby sobbed uncontrollably at his actions, he did not suspect the guilt would be this bad, "Please forgive me."
"Robby, just stop, it's ok. Alright, just relax," She comforted him, her hands trailing down his back.
Robby sniffed a few more times, propping himself up on his elbows, looking down into her loving eyes, "It just came over me, and we've been here so long, and I -- "
"Robby, enough, it's fine," She said, caressing his face. "It's over and done with."
"I'm sorry mom," Robby said, calming down, his breathing returning to normal.
Chapter 2
Robby's Aunt Cori greeted them when they returned to camp, "Where'd you two go?"
"Went for a walk," Robby's mother, Karen, answered before Robby could say anything.
"Ok, well there's some of that fish left if you two want to split it," Cori nodded in the direction of the large fish they had captured. It was rare, but a beautiful thing. In the three months they've been there, they've managed to catch maybe five good sized fish to cook up. Coconuts, clams, oysters, and an occasional trapped lizard usually consisted of their meals.
Karen sat next to Robby on the log by the fire, her arms entwined in his. He took a couple bites and offered it to her. Opening her mouth, he slid a piece in, her lips tracing his finger. Sitting by the fire, stoking it, putting more wood on it, Robby calmed down. He shook his head at their situation.
"Mom, I'm -- " he whispered before being interrupted. Cori had fallen asleep.
"Robby, I said forget it. It happened, it's done. Alright?" Karen whispered back, leaning her head on his shoulder.
"I'm sorry if I hurt you," Robby sighed.
"It was a little uncomfortable," Karen said, patting his forearm. "Don't worry about it."
Robby's risk paid off, his mother wasn't too angry, she understood, knowing his teenage hormones pushed him over the edge.
A couple hours later, Robby began getting sleepy, his eyes heavy. He felt his mother slip out from under his arm. He lowered his head to his knee, resting it on his forearm. He a few moments later, just before sleep began to take him, he heard his mother clear her throat from somewhere behind him.
Robby turned to the direction of the sound behind to see his mother nude, the light from the fire illuminating her skin. "Robby, let's go back to the pool."
They became one with the water, one with each other, mother and son giving everything to each other. Robby stood in the shallow pool, his mother's legs wrapped around his waist, the waterfall behind them. He pumped upward, slamming into her, grunting as he worked. Karen moaned, her mouth hanging open, her hands clasped behind Robby's neck. Peering into each other's eyes, they climaxed together this time.
Karen slowly turned to her former lover, the waterfall; as if to tell it she had a new lover, a human this time. Her orgasm built up, surging through her spine, her arms wrapping around Robby, pulling herself against him.
Night after night, they met after Cori went to sleep. Night after night, in the pool, making love, the jealous pussy-licking waterfall, watching on silently. After a week, their love making sessions included a morning bath, another week, and Robby mounted her from behind while she held on tightly to a coconut tree, both shaded from the burning noon sun.
It was only a matter of time on that little deserted island that Aunt Cori would discover them.
****
Cori and Karen slammed Robby against the waterfall, attacking him with kisses, licks, and sucks. It had been three days since Cori found her sister and nephew in the throes of passion. Getting back to camp before they did, she waited. When they finally arrived, Cori stood, removed her ragged clothing and presented herself to them, silently asking them to be part of their new relationship. Karen and Robby stood, not saying a word, and removed their own clothes. The three of them had been naked ever since.
Robby was exhausted, pleasuring both women every chance he got. Gathering wood, coconuts, and clams took longer due to having to stop to tend to one of the women's needs. He loved it.
A few weeks passed, Robbie sat at the camp one night, watching his mother and aunt. They stood facing each other, holding hands, their bodies nearly silhouettes due to the fire behind them.
Robbie watched them become one that night. He moaned as their first kiss ended, their tongues recoiling slowly back into their mouths, leaving a string of sparkling, fire lit saliva between them.
The two sisters went at it for hours, exploring each other's bodies, grinding their pussies together, ending their session by swallowing Robby's seed after a lengthy blow job. Robby smiled, looking to the starry sky, while his mother and aunt, kissed once more, sharing his semen.
Robby was the king of that island, his mother and aunt, his queens. He hoped they would never get rescued.
