A Spectator Sport

It started with a kiss. That sounds innocent enough, but take Percy's word for it: that couldn't be further from the truth.

Their tongues found one another, embracing in the neutral space between their mouths, but that was only half of the full picture. Silena's hands roved Percy's body like Tantalus let loose in a grocery store. One moment she was gripping tufts of his hair, the next he felt her nails sliding down the side of his neck to feel up his collarbone of all things, then they were dipping down to grope his muscles. It wasn't long before one gave his firm buttocks a good squeeze. The onslaught wasn't limited to her hands, either. Her breasts were so large that they not only bridged the gap between them, but were even pushed flat to lack of space. Silena frequently flicked her hips forward. Every time, the motion was perfectly calculated to barely brush the coarse fabric of her panties against the swollen head of Percy's erect cock.

It felt amazing. But Percy refused to be tempted.

His hands found each of Silena's wrists, easily overpowering the greedy limbs. Within seconds her hands were pinned to the armoire as Percy took an extra forward, making those tits flatten even further against his bare chest. Silena looked slowly left, then slowly right, eyeing the grip he had on her.

"Oh, my," she said, followed by a chain of giggles.

Percy's dick rubbed up against her stomach, reaching as high as Silena's belly button. Goosebumps formed on Silena's skin around his shaft. Percy imagined that was her body's way of showing its anticipation; they both knew what was coming.

For a while they stayed like that, unmoving. Percy's eyes found Silena's. Slowly, even their breathing synced up. Neither of them said a thing. They both held back for as long as possible, all so that when the moment finally came… 

They exploded into motion.

Percy released Silena's hands. They didn't snap back to his body, instead sticking obediently to where he'd placed them. He grabbed her bra with both hands. Roaring, he snapped it in two with nothing but strength, tossing it aside behind him.

He figured that was only fair. Now it matched the old thong that originally went with it.

Speaking of thongs, the replacement for the one he snapped nights ago was also in the way. This one, he didn't bother breaking. He didn't bother taking it off at all. That would take too long. He just shoved the fabric to the side and shoved his cock inside.

It wasn't all that romantic or gentle, but the time for both of those was long passed. There was still a subtle haze clouding Percy's head.

He had to satisfy Silena. If he did that, he passed this lesson. He could rest then… and in order to get there, he just needed to focus on doing what he had to.

Silena gasped, but it didn't last long as Percy's lips captured hers. His arms came up, elbows pressing Silena's arms back against the wood while his hands shamelessly groped her breasts. His body moved jerkily as he thrusted against her. Grace, dexterity and timing were all shot to Hades by now. He was running on willpower and distilled lust.

His fingers rubbed roughly over Silena's stiff nipples. Although it was faint, his legs were shaking. He felt like he'd run five miles with Tyson strapped to his back, but he still refused to stop.

Not yet. Not now. Not until the time came.

Silena was more than a passenger. As he continued to drive their hips together, she began moving herself. Subtly at first, then stronger, she undulated in time with him, dropping herself onto his thrusts to drag out every last centimeter of penetration. While she wasn't gushing down there like the two girls before her, she was wet enough to let them keep up the frantic and desperate pace.

Their kiss broke. Both of them panted out hot and short gasps, Percy in particular. Even Silena's breath smelled nice, spicy like peppermint. Her lipstick had become smudged in the wild kissing. Their foreheads rested against each other as they fucked. Somehow, maybe because of the exhaustion, it didn't quite feel real.

Percy had a confession to make. He'd harbored a slight crush on Silena for years. He was pretty sure every boy at camp below a certain age did. It wasn't love — not the romantic kind — but a certain level of raw attraction was impossible when faced with a knockout, mature older girl that took such careful care of so many young campers. Everyone remembered the first time they met her— always immaculate in appearance, always smiling, always willing to lend you an ear and a hand.

He pulled back, separating their heads, and really looked in front of him for the first time.

Silena's enormous bust swelled and shook side to side, spurred on both by her own rises and falls and the shockwave following each of Percy's brutal thrusts. That perfect makeup was ruined, the eyeliner trailing from sweat and the lipstick smeared, yet to Percy it had never looked better. Her eyes were still kind just like they were when she'd listen to whatever silly problem you were dealing with. That hadn't changed, and yet something was different. Something else had mixed in. Percy almost called it lust, but that wasn't quite right.

It was pure pleasure, the type that could only be born to overflowing passions. It was eroticism in its final form. It was… hot as shit.

Roaring again, even louder than when he tore apart her remaining clothes, he grabbed Silena by the back and twirled away, dragging her from the armoire. The two fell to the floor with him on top, landing with a heavy smack that they were both too distracted to notice. His hips teamed up with gravity to drive him deeper yet into her depths. Silena moaned and wailed. Her hands shot out to the sides, nails digging into the carpet.

Under all of that noise, neither of them noticed the light squeak that came from the other side of the armoire's door.

When Piper McClean got Silena's sudden invitation for a Camp Half-Blood visit, she was overjoyed.

It was unexpected, sure, but there was hardly anyone that had been as much of a guiding light in her life than her older half-sister… even though they only met when she was already in high school. Silena was simply the type of person you could rely on, a type that had been sorely lacking in Piper's life considering her dad's faults. After months away, she jumped at the chance to revisit her home away from home, borrowing her neighbor's car the very same day the message arrived.

It wasn't stealing if said neighbor agreed. And if a little bit of charmspeak leaked into Piper's voice as she asked, well, that was hardly her fault. Demigod powers were hard.

For the first day, everything had been great. She got to know the newer campers, spent the entire day hanging around with Silena, and even Drew was strangely out of it and not as obnoxious as usual. She could hardly imagine a more perfect day, right up until all but three of the campers filed out of the cabin and Silena shoved her into a piece of furniture.

The walk-in closet had caught Piper's eye when she walked in, but it wasn't like she thought twice about it. These were daughters of Aphrodite. Space to put more clothes was about the least shocking new addition the room could've seen.

She never expected the size wasn't about fitting in more clothes, but about fitting her.

"What's even happening right now?" Piper had exclaimed. "You can't just put people into furniture, Silena. Don't tell me you gave my bed away and I'm supposed to sleep in here."

Even as Silena answered the question, she was pulling her shirt off. Behind her, Drew and Valentina, the only other two that had stuck around, were stripped naked and slowly pulling on some of the most over-the-top lingerie Piper had ever laid eyes on. 

"Honey, words would be a waste," Silena had said, smiling kindly. "Rather than listening to me just watch, and listen to your body."

And she shut the door, closing Piper in the dark.

Except, it wasn't really all dark. There was a spot of light, looking almost blue because of the background, just big enough to peer through.

Piper thought about slamming the door open and bursting out, she really did. It wasn't like the dresser was locked. But part of her was going crazy with curiosity. What could this possibly be about that had Silena acting this way?

So she stood and waited, and she wasn't waiting long.

All her half-sisters had quickly suited up in their outrageous uniforms before settling down on another feature Piper didn't remember: a bed bigger and fancier than any of the rest. Then, just a few minutes later, Percy Jackson of all people walked in.

Piper was shocked to see her friend stride into someone else's cabin with a clear air of familiarity. And that was the least shocking thing he did all night.

Piper watched her sisters spring up and service Percy like he was an Olympian himself. She watched him decimate the ever-uppity Drew and pound her into anthropomorphic oriental pudding. She watched Valentina submit to him, and more than that, she watched him take complete control of her. Piper had seen Valentina leave even some of the most experienced boys at camp shaking, and yet Percy had her completely at his mercy. It was a side of him she had not only never seen before, but couldn't have imagined without seeing it for herself. As she stood there marveling, her hand drifted down to her jeans.

"Surprising, right?"

Piper jolted. From her peephole, she could just barely see Silena standing on the other side of the door.

"What is this, Silena?" Piper asked. "Why are all of you doing this? And with Percy, of all people?"

"It's the lessons," she said, like that explained anything at all. "We're teaching him… although, between us, I'm not sure how much there is left for us to give."

Piper just watched as Percy continued to plow Valentina. They were teaching him? If anything, though, it seemed like her sisters were the one getting the lesson.

"This is the last of the lessons," Silena confessed. "All we can do is test his endurance now. He's off to a good start, but there's still lots left to do. He's come so far in the last week."

"One week?!"

Piper couldn't help the way she raised her voice. Was Silena seriously implying that a week ago, Percy had never been with a woman? He'd already risen to a half-standing position that was letting him plunge into Valentina at speeds a mortal body may not have been able to handle. Piper unconsciously chewed her lower lip. She could tell right away when he came, and not just because half of it promptly leaked out and streaked down Valentina's dark legs.

"He's a fast learner," Silena said. Suddenly, and seemingly without warning, Percy slapped his cheeks hard enough to make Piper jump. Silena turned away from her. "I think that's my turn. I've got to admit, I've been waiting for this."

And before Piper knew what was happening, Percy had her older sister shoved up against her hiding spot like a common slut.

Silena's back blocked Piper's peephole, leaving her in proper darkness for the first time. She couldn't see anything, but she could hear everything.

She heard their flirtatious banter. She caught the wet swishing of their interlocking tongues. She listened as Percy's thuds impacted the armoire's exterior. And above all, she noticed the exact moment he began to thrust that monstrous cock deep inside Silena's innards, wet slurping mixing with the sound of smacking flesh.

Piper could taste a hint of blood now, owing to the force her teeth had been applying to her own lip. One hand came up to her chest, groping breasts only slightly smaller than Silena's. How different would Percy's powerful fingers feel? Meanwhile, her other hand dipped down, pushing against the hem of her jeans before sliding under. How many times larger than her fingers was that cock? At least five times, maybe six or seven.

A finger teased her own entrance, finding it wet to the touch, but Piper barely felt her own fingers, preoccupied with imagining something far larger.

Her imagination proved so distracting, in fact, that Percy's sudden roar made her audibly yelp, smacking backwards against the deepest part of her hiding spot.

For a moment she froze. Even though being shoved away in here was hardly her choice, she couldn't shake the feeling of being covert, like being caught would reveal some kind of guilt. It wasn't a totally unpleasant feeling, lending an extra thrill each time she caressed her own body, but it did make her heart hammer in her throat.

Slowly, she crept back to the peephole and peered out.

What she saw made her gasp.

She certainly hadn't been caught. Percy hadn't even glanced her way. In fact, looking at him, she was fairly sure a full-grown hydra could slither past away and he wouldn't notice a thing. That was just how utterly focused he was on Silena.

They didn't look like the people Piper knew and respected anymore. The way Percy growled and poured his all into thrusting down with his hips made him look like a wild beast. And Silena, pressed to the floor beneath him, looked like his mate. Or maybe not even that. She looked like his plaything.

Piper was already back to touching herself, but it wasn't enough. She tore her shirt off and pulled down her bra, baring her larger dark tits to grasp them better. But the strongest pinches she could apply to her nipples only felt like a pale imitation as she watched Percy's teeth sink deeply into Silena's. She unbuckled her jeans and plunged three full fingers into her folds, and still they paled in comparison not only in length but even to the girth of Percy's cock.

She'd forgotten entirely about attempting to keep her voice down. Luckily, Silena's unfettered screams blotted out Piper's wild moans. The warbles that echoed out of Piper's throat were as much from desire to experience more than they were about any stimulation she was managing to generate herself.

Her eyes slid to Drew, and she imagined herself in the girl's place, treated like a toy beneath Percy's powerful muscles. Her eyes moved to Valentina, still frozen in the posture of a mating cat— head down, back sloped, ass up. From a position like that, just how deep would Percy reach inside her if Piper was the one taking his cock?

Finally, her eyes returned the floor and the spot her role model was screaming and cumming. Silena and Percy had landed directly in front of Piper, giving the native girl a view from directly behind. She watched his hairy balls rise and fall as his slick shaft repeatedly rose into view before burying back out of sight. As she watched those testicles smack down against the increasingly soaked area between Silena's legs, Piper came to a shocking realization.

For as long as she could remember, Piper had become accustomed to not settling for less. It wasn't a conscious thing, and it wasn't arrogance, it was simply the way she lived. With her famous father and stunning looks, people simply fawned over her. Whether she liked it or not, she would be the center of attention wherever she went, and after a while that rubbed off on her tastes.

In bed, she liked men to worship her. Nothing turned her on like a man slaving away to please her. She controlled the tempo. She controlled the mood. She would ride them until their hips gave out, and feel the thrill the entire time. Whenever a man caught her eye for his looks, the first thing she pictured was that lovely face buried in her crotch, tongue working to please her.

Which brings it back to why what she realized while in that armoire was so shocking. When she pictured herself joining in, hurling herself at Percy and Silena, she imagined crawling up to those hairy testicles and licking them clean. The mere idea sent waves through her body strong enough to make her legs shake, despite the fact that it couldn't have been more different from her usual fantasies.

Percy jerked his head up, pulling one of Silena's breasts up with him by his teeth. He pulled so hard, Silena's back rose slightly off the floor. She wailed like a rescue siren. A moment later, Percy erupted inside of her at the same time that Silena came. More blood leaked into Piper's mouth as her teeth sliced her lip fully open. It was the sight of those hairy balls, wet with Silena's juices and the little bit of Percy's own cum that dribbled up out of her, that threw Piper over the edge. A moment after the coupling pair, Piper reached her own orgasm. She dragged dripping fingers out of her folds, breathing hard.

With his last wad shot, Percy rolled off of Silena. She didn't move, fucked comatose just like the other two sisters. After moving onto his back, Percy didn't move either. Piper stared out, wondering if she really would have to spend the night in this dresser, when she heard the sound of snoring. Percy's eyes were closed. After that last dash over the finish line, he'd passed out and slipped straight into sleep. 

Carefully, Piper pushed open the dresser. Still half-naked, she crept across the floor on tiptoes. When she reached her destination she stared down. Still half-hard, Percy's cock was dirty with a concoction of juices accumulated from all the different partners, including his own cum. Slowly, Piper knelt down. Gently, she guided his partially-flaccid member straight up.

And she licked his penis clean.
