Painful Explanation: Once upon I time, I wrote a series of three Thunderkittens stories. Then, in a computer mishap, I lost the middle one. The only place I ever posted the middle story was on a Yahoo group that was shut down years ago, so that story is lost in the digital ether.
To briefly summarize it, Wilykit and Wilykat awoke together, had a full day of chores and training with Panthro, and then ended up in the shower together. There, they experimented clumsily with oral sex, and also discovered that their feelings for each other go beyond mere teenage lust.
Up to speed? Good! We now join the Thunderkittens, who have just finished their shower and rushed to dinner with the adult ThunderCats.
***
For all the panic involved in getting there on time, dinner proved surprisingly pleasant. In fact, Wilykat found that he felt more relaxed than he had in a long time. The amazing thing his sister had done for him in the shower had drained every drop of tension right out of him, leaving his body pervaded with a sort of pleasant weakness. It felt as if everything was right with the world, which was not a feeling Wilykat had experienced much since coming to Third Earth.
This did not mean, however, that he didn’t take every opportunity to exchange knowing glances with Wilykit, or to touch her hand or her leg under the table. In fact, as the night wore on, his need to do these things--and more--grew stronger. By the time dinner was over, Kat was getting a bit anxious for he and Wilykit to return to their room. Kit clearly felt the same way, because soon after she and her brother had helped Snarf clear the table, Kit declared herself exhausted and said she was going to turn in early. Kat followed her lead and they both headed back to their room, ignoring the odd looks they received from the adult ThunderCats.
Kat didn’t yet feel the burning, relentless, physical need that had consumed him that afternoon in the shower, or in his bed the night before. This time, he thought, he could take it slowly, one step at a time—which, he hoped, might improve his chances of doing it right, whatever that might mean. Like Wilykit, Kat couldn’t escape the feeling that there was something more he wanted to do with Kit, even though he couldn’t say just what it was.
After they entered their room, Wilykat closed the door behind them and pulled his sister close.
“I love you,” he said, gently touching her cheek.
“I love you so much I can barely stand it,” Kit replied.
They came together for a long, slow kiss. Then Kit embraced him, shifted a bit, and fell back onto her bed, pulling Kat down on top of her. Her arms and legs wrapped around him, and they just held each other that way for a long while. Wilykat inhaled and lost himself in Kit’s scent and the feel of her soft, warm body against him.
Soon, Kat began to feel a warm tingling in his groin, no doubt because it was right up against Kit’s. Remembering from the previous night how pleasurable the friction between them could be, he rocked forward and back, ever so slowly, on top of his sister. His penis stiffened inside his shorts, so he maneuvered his hips so that the underside of his shaft pressed against Kit’s groin as the twins moved against each other, eyes closed, focusing on nothing but the sensations rippling through their bodies.
“Ohhhh, Kat,” his sister whispered in his ear. “This is so nice…”
Wilykat let Kit roll on top of him. She peeled her leotard down, exposing her small breasts and flat stomach, then wriggled out of the garment and tossed it away. Kat smiled as he admired her. Wilykit grinned back at him, then grabbed the hem of his shirt and yanked it up and off. Wilykat followed suit by shucking off his shorts and kicking them away.
Kit settled back down onto Kat’s hips. Wilykat’s hard member rested in the cleft between his twin’s legs.
“Wow,” Kat breathed, looking up at his sister’s lovely torso and sweet, smiling face. “You’re so beautiful.”
His hands slid up her sides and cupped her little breasts to knead them gently. Kit closed her eyes, then began to shift her hips forward and back, massaging the underside of Kat’s shaft with her vagina.
They did this for several minutes. Both twins shut their eyes so that they could concentrate on the delightful, teasing sensations their movements produced. Kit’s breasts grew firm in her brother’s hands, her nipples bullet-hard. The feeling of touching her was absolutely exquisite.
But Kat wanted more. He pulled Kit down and kissed her; their tongues met and massaged each other with ever more intense desire. Kat rolled over on top of his sister and grasped her fiercely, loving her, needing her. Kit spread her thighs and reached between them to grasp Wilykat’s shaft, making Kat inhale sharply. She used the head of his penis to divide her labia, then rubbed it up and down in the wet, smooth, heavenly place between them. Kat breathed hard; it felt so good. Yet he still wanted more.
He felt an impulse to push forward, and he did so, gently, so as not to accidentally remove his penis from Kit’s delightful grip. The head of his member pressed up against the rear wall of Kit’s vagina and slid upward. Kit stopped it before it could slip free completely and moved it back down, then let Kat push again. Once again, she stopped its upward slide and moved it back down, this time all the way to the lowest part of her vagina.
Kat pushed a third time, and then it happened—instead of sliding upward, the head of Kat’s penis found the opening of Kit’s vulva and began to enter. Kit gasped and reflexively tightened her grip on Kat’s member.
“What is it?” Kat whispered. “Are you okay?”
Wilykit looked up at him, wide-eyed. “It- it hurts a little. But keep doing it!” she quickly added. “Just go slow.”
Wilykat gently applied pressure with his hips and felt the head of his penis slip fractionally deeper into his sister’s opening. The motion was tiny, but the feeling was electric; pleasure flashed through Kat’s body like lightning. Nothing in his life had ever felt as good as this.
His body screamed at him to thrust harder, to get all the way inside, but he held himself back, going slowly so he wouldn’t hurt Kit. Kat gently pushed again, eliciting a whimper of combined pain and pleasure from his sister. He hoped the pleasure was greater; he wanted Kit to feel as wonderful as he felt right now.
Carefully, he eased in farther. His penis sank deeper and deeper into Kit’s vulva until, at long last, it was all the way in. Wilykat looked down at his sister’s beautiful face, and she looked up into his eyes.
He was inside Wilykit. Inside her. He loved her more than anything, and now it was as if he were an actual, physical part of her. There couldn’t be anything in the universe more amazing and special and intimate than this.
Kit reached up and stroked his cheek. “Oh, Kat,” she whispered. “This is what I wanted to do with you, even though I didn’t know it.”
“Yeah,” Kat breathed.
Kit pulled him down and kissed him. The movement caused Wilykit’s hips to shift backwards momentarily, pulling his penis partway out of Kit’s vulva. Almost reflexively, Kat thrust back in. It felt so good that he and Kit moaned both at once.
Still kissing Wilykit, Kat began to thrust slowly in and out of her. Kit’s grip on him tightened; obviously, she enjoyed the sensation as much as he did. He pushed his tongue into her mouth and kept pumping, instinct beginning to take over. Beneath him, Wilykit (who had always been extremely flexible) spread her legs in almost a complete split to make sure that every inch of him could get inside her.
The twins panted as Kat thrust faster and faster into his sister. Kit lifted her hips to meet every thrust, driving Kat’s penis deep inside her again and again. Kat’s head hung down next to Kit’s, his face in her hair. He breathed in her scent; he listened to her soft moans; he felt her warm body against him and the heat inside her that surrounded him. With every sense he experienced her, reveled in her.
Kit was breathing harder and harder, and her moans were getting more frequent and higher-pitched. Kat felt his release approaching and thrust even faster, each time penetrating as deeply as possible into his sister’s young body.
Suddenly, Kit’s hands gripped his forearms with incredible force. Her vagina squeezed his member hard. She looked like she wanted to scream, but instead she just let out a long, high-pitched whimper.
The sound and Kit’s clasping vagina pushed Wilykat over the edge. He made one last powerful thrust into his sister and held her tight as ecstasy overcame him. His body convulsed, his head flew back, and gout after gout of semen erupted from him, flooding Kit’s vagina. It was the greatest thing Wilykat had ever felt. He never wanted it to end.
Finally, both twins’ orgasms subsided, and the two lay panting, Wilykit spread-eagle on the bed, Kat still on top of her and inside her.
“That…that was…” Kat gasped in Kit’s ear.
“Uh-huh,” Kit whimpered.
After a few minutes, Kat’s member softened and slipped out of Kit’s vagina. He rolled off her so that they lay side-by-side, hands clasped as they gazed dreamily up at the ceiling.
“Uh-oh,” Kit said in a faraway voice.
“What?” Kat asked.
“I think we made a mess.”
She scooted back slightly, and Wilykat saw a big, pinkish-white stain on the bed sheet where her vagina had been. Even now, a little more of the stuff was leaking out of her.
Wilykit cupped her hand around her vagina and got up. “Oooh,” she groaned as she waddled toward the bathroom. “I’m a little sore.”
While Kit washed up, Wilykat pulled the sheets off Kit’s bed and tossed them into the hamper, then went into the bathroom himself. Kit, having sponge-bathed, was just drying off. She still looked like she was in a bit of pain.
“You okay?” Kat asked.
“I think so,” Kit said. “Maybe it was just because I’d never done that before.” Then she put a hand on Kat’s cheek and looked in his eyes. “But I’m so glad we did.”
Kat nodded soberly. “Oh, yes.” Then he looked at her and smiled. “Good thing I’ve got laundry duty first thing in the morning.”
“Yeah,” Kit agreed, also grinning.
Wilykat took his sister’s hand. “C’mon,” he said, “we can sleep in my bed.”
