Chapter 1: Second-Degree Heat
It was mid-afternoon, and sixth period at Eastside High School had just ended. Now, Kevin Grant-Gomez was heading down the second-floor hallway, nodding and waving to various classmates as he made his way toward his seventh and final class of the day, trigonometry. After that, he'd be chauffeuring his much younger sister, Gretel, to soccer practice. In the abstract, that seemed a little ridiculous, given that Gretel had superpowers and could fly anywhere she pleased, but she and Kevin had to keep up appearances for the sake of maintaining Gretel's secret identity—especially as far as their parents were concerned.
Unbeknownst to Kevin, at that very moment, a hooded, masked figure in a white-and-tan bodysuit was crouched in one of the school's janitorial closets, holding a metal cylinder about the size of a soda can. They twisted the lid off the cylinder as they spoke in a gender-neutral, electronically disguised voice.
"Time to put the powers of Doctor D'Zire to the test."
Kevin stopped in his tracks when he noticed a strange smell in the air. The scent seemed to be simultaneously floral, musky, and metallic. Kevin had never smelled anything quite like it.
But before he could consider what the strange odor might be, or where it had come from, Kevin was overcome with the most intense lust he had ever felt in his young life—which, for a teenage boy, was really saying something. Despite never having had sex, Kevin suddenly burned with the need for it.
Yet as the teenager looked around frantically, no girl, boy, or teacher seemed to register as someone with whom he could sate his burning desire. Even the hottest girls in the hallway didn't appeal to Kevin any more than the locker doors. It was as though he were ravenously hungry but was trapped in the wrong aisle of the supermarket, surrounded by nothing but boxes of aluminum foil and rolls of paper towels.
Kevin felt like he might go mad at any moment, but he forced himself to think. What could he do to assuage this powerful urge? Who could help him?
Thinking about people who often helped him brought Fred to mind. Instantly, Kevin knew that he needed her. Desperately.
Other kids were running by him in both directions, but Kevin scarcely noticed. He only just barely registered a senior girl making out in the hallway with her younger brother.
Where would Fred be now? It was sixth period, so…English? Yes! Mrs. Dugan's English class!
He ran for the stairs and hurried down toward the first floor, where Mrs. Dugan's classroom was. But when he reached the landing between the second floor and the first, he heard from somewhere below him the sound of a locker slamming shut. Then his cousin came running into the stairwell and rushed up toward him.
"Fred!" Kevin shouted, in the tone in which a man stranded in the desert might shout "Water!" upon sighting an oasis.
"Kevin," Fred half-panted as she reached the step just below the one her cousin was standing on. "I'm…having more feelings than I'm comfortable with."
Kevin could relate. "Let's go up to the library. We can, um, talk about it in a study carrel."
Fred was so consumed with urgent lust for Kevin that her brain was basically on autopilot as she replied in a monotone, "Yes, I would like to speak with you in a secluded location."
Kevin grabbed Fred's hand and gasped, "Come on."
At a brisk jog, Kevin led Fred back up the stairs, down the hall, and through the double doors of the school library. They passed by a study carrel where twin sisters Abby and Gabby Xu were making out frantically while literally tearing each other's clothes off.
They found an empty carrel. Then Fred grabbed Kevin, pulled his body tight against hers, and kissed him.
Kevin felt aflame. He held Fred as tightly as she was holding him and returned her open-mouthed kiss ardently. When they broke off the kiss, both of them were breathing hard.
"What the heck…is happening…to us?" Kevin panted.
"I don't…even care," Fred gasped.
Kevin immediately seized her and kissed her again. She wrapped her arms around him and made out with her cousin like crazy.
After untold minutes of kissing, Kevin found himself craving oxygen only slightly more than he craved his cousin's body. He broke off the kiss and looked at her, gasping.
"More," he panted. "I need more."
The laconic Fred didn't reply in words; she just threw off her reddish-brown jacket, then pulled the purple vest she wore beneath it up over her head before doing the same with her white T-shirt.
Why the fuck do I wear so many clothes?! she thought as she reached behind her to undo her bra clasp.
"I don't know what I'd do if you weren't here at school," Kevin panted, pulling off his short-sleeved orange jacket and then his brown T-shirt. "I'm really glad we're second-degree relatives."
"Let's hurry up and get first-degree naked," Fred replied breathlessly, yanking her bra off and hurling it away before wrestling her pants and panties off simultaneously.
Kevin did the same, and then each of them was standing nude before the other. For a long moment, they stared unabashedly at each other's bodies. Kevin found the little swells of Fred's breasts exciting to look at, and the normally unexpressive Fred couldn't help but grin maniacally at the sight of Kevin's erect cock, which bobbed slightly with his heartbeat.
Fred grabbed Kevin by his bare shoulders and kissed him fiercely, pressing her aching-hard nipples against his chest. Then she ended the kiss and moved backwards, pulling Kevin with her to the study carrel. Kevin got the idea and yanked the chair away, whereupon Fred hopped up and sat her bare ass on the desk portion. She looked hungrily down at Kevin's hard member.
"Put that in me," she gasped.
"Wait," Kevin gasped as one rational thought fought its way to the surface of his ocean of lust. "What about, you know, protection?"
Birth control was the last thing Fred wanted to think about right now. So she simply panted, "We're good. Put it in."
In his current state of extreme horniness, Kevin found Fred's response to be more than adequate to allay his concerns—which went completely out of his mind as he positioned his cockhead at Fred's entrance.
He tried to take it slow, but he just couldn't; instead, he pushed almost his entire length into Fred's pussy in a single thrust. Both cousins cried out "AAH!" as the pleasure of penetration hit them like sweet lightning.
And now that he was inside her, Kevin couldn't do anything but seize Fred by the shoulders and start fucking her. Her hot, tight love-channel around his member made every movement intensely stimulating. And the way she looked at him, her eyes full of lust as she panted and sweated, only added to that intensity.
Fred threw her arms and legs around Kevin, needing him close and needing him deep. Nothing she'd ever felt in her life had been as powerful as this, and she didn't want it to stop for even a fraction of a second.
"Oh, Fred," Kevin breathed in her ear as he pumped his cock inside of her, the tip of cock touching bottom on every stroke. "This is incredible…I can't stop…I never wanna stop…"
"Definitely don't stop," Fred gasped. She was moving her hips forward and back as best she could to help Kevin get all the way into her again and again. "Don't stop for anything."
Turned on even more by Fred’s words, Kevin fucked her faster, making her gasp. But he needed more than that, more of himself inside Fred. So he lunged his head forward and tongue-kissed her deeply. She moaned into his mouth; then she moaned louder when he used his grip on her ass to work a finger into her tight asshole.
Fred disengaged from the kiss and panted in his ear, "Oh…God…yes…get inside me…everywhere…"
She again pressed her mouth against Kevin's so she could move the full length of her tongue against his as they fucked. She also moved her hips in time with his while wiggling her ass just a little to encourage Kevin to push his finger deeper inside. To her gratification, he took the unspoken hint and worked his finger into her to the second knuckle.
Now horny beyond her wildest imaginings, Fred used her arms, legs, and hips to try to get Kevin to fuck her faster. Again, he took the hint, and then he was pounding her pussy as hard as his teenage body could. Which was pretty damn hard.
"Fuck…me…Kevin," Fred grunted. "Fuck…me…AAAAAH!"
The hard fucking plus hearing his notoriously unexcitable cousin cry out in ecstasy were more than enough to make Kevin's climax hit like a freight train—a freight train thrown by Gretel.
"YAAAAH!" he cried, shooting what felt like an enormous load of seed deep inside Fred.
Fred clutched Kevin to her, embracing him and his cock and his semen that was so far up inside her that she could feel its heat at her very core. Then, when her climax passed, she released Kevin and looked at her panting cousin's face.
"That…was…amazing," she gasped. Then she put both hands on Kevin's face, and her voice had a note of desperation as she said, "But…more."
It took only that single word, infused with need and desire, to make Kevin's cock stop softening and, within moments, become rock-hard again. He took a single step back.
"Turn around," he said hoarsely.
Fred immediately understood what Kevin had in mind. She got off the edge of the desk and turned her back to Kevin. She felt her cousin's semen running down her inner thighs, but the sensation only made her hornier. The only thing she wanted in the world at that moment was more filthy, incestuous, utterly taboo sex with Kevin, right there in the school library.
Kevin watched eagerly as Fred bent forward, bracing herself against the desk. Her pussy seemed to open of its own accord, as though hungry for his cock. And Kevin couldn't wait another moment to sate its hunger.
He seized his cousin's hips, put his cockhead in place against the entrance to her love-tunnel, and shoved in hard.
“YES!" Fred cried, shocked by the powerful pleasure of penetration and the strength of her need for more. "Fuck me! Fuck me!”
Kevin started pumping. Then, remembering through the haze of his lust what had aroused Fred so much during their first coupling, he put his thumb against the side of his cock as it moved in and out of Fred's pussy to liberally coat it with some of her plentiful natural lubricant before pushing it into her pink asshole.
“Oh, God, Kevin!" Fred shouted.
Kevin couldn't believe how quickly and with how much force his arousal had returned, and Fred's horny shouts were doing nothing to tamp it down. He'd expected that he and his cousin would take it a little slower on this second round, but it was obvious now that neither of them wanted to.
So Kevin started pumping Fred's pussy good and hard, making sure to thrust his thumb in and out of her asshole at the same pace.
Fred shouted "Oh fuck!”, but these were the last coherent words she managed to produce; thereafter, she could only pant and grunt like a rutting animal, conscious of nothing but the intense pleasure of being fucked—especially being fucked by her cousin—and her burning need for more. She shoved her ass back against Kevin's hips to ensure that the boy's cock was ramming all the way into her on every thrust the way she needed it to.
Kevin, too, had lost the power of speech; he needed every cubic millimeter of air he inhaled to fuck his cousin harder and faster. The only thing in his mind now was fucking her, and needing to fuck her even more.
Fred gasped as Kevin pounded her pussy harder than she would have guessed he could. Her knuckles turned white from gripping the edge of the desk with all her strength, not wanting to risk losing her hold and interrupting the fucking for even a fraction of a second.
And then Kevin thrust in deep, deeper than ever before, and shouted “YaaaAAAAAH!" Fred could feel her cousin's hot seed shooting into her innermost place, and she screamed "AAAAAAAH!” as she climaxed along with him.
For almost a minute, Kevin stood there panting, keeping his cock inside Fred. Then Fred started to straighten up, and Kevin pulled out.
Fred turned around and looked down at herself—chiefly at the rivulets of cum that streaked both the fronts and the backs of her thighs. Then she looked up at Kevin with what was by far the biggest, goofiest smile Kevin had ever seen on his nihilistic cousin's face.
“You made a real mess of me, cuz," she said.
Kevin blushed. "Yeah, sorry.”
"No, you dope, that was a compliment.”
Fred's mindset grew more serious. She was torn between what she thought she should say next and what she very much wanted to say next. She decided to compromise and do both.
"Kevin," she sighed, “I think I need to go clean myself up and then get out of here. But how about we, you know, put a pin in this?”
Kevin, still catching his breath, replied, “That, that sounds great."
He went over to pick up his pants from where they’d landed on the floor. By the time he turned back around, Fred and all her stuff were gone.
