Chapter 2
Three days had passed since the incident with Stitch. He hadn’t done anything bad or weird since then. Now, Lilo was hopeful that it had been a one-time thing, and that maybe she could forget it ever happened.
That evening, David—Nani’s friend or boyfriend, Lilo wasn’t sure—brought over dinner, and they all ate together and watched some TV. Then Nani sent Lilo, and by extension Stitch, to bed while she and David continued talking. Not long after Lilo had bathed and put on her nightgown, she heard the front door shut and the sound of David’s scooter driving away.
It had all been very pleasant. As a result, Lilo had no trouble falling asleep that night, all worries banished to the back of her mind.
***
“Lilo.”
Lilo’s sleep-slowed brain couldn’t do much, but it at least recognized the voice as Stitch’s.
“Lilo,” the alien whispered again.
“Nnnn?” Lilo murmured groggily. “Whaizzit, Stitch?”
“Stitch need Lilo’s help again.”
Lilo’s eyes opened, and the girl gasped. Hovering directly above her face were Stitch’s two thick, black members, barely visible in the dim light from the window. Both were as “full” as they had been the other night, when Stitch had almost drowned Lilo in the thick white liquid that came out of them.
“Oh, no,” Lilo whispered, shaking her head. “Stitch, I can’t. I can’t do that again.”
“Please,” Stitch said. “Stitch in pain. Stitch could die.”
Lilo looked up at him, her big eyes pleading. “Isn’t…Isn’t there some other way?”
“No, no other way,” Stitch said. His tone was odd—both sad and eager, Lilo thought.
“Please,” he repeated. “Lilo get on knees now.”
Before Lilo could respond, Stitch put his hands on her shoulders and effortlessly pulled her up into a kneeling position on the bed.
“Stitch, wait, I- Nnnnnnh!”
The blue alien grabbed Lilo’s head and shoved his upper cock into her mouth, forcing it open wide. Reacting instinctively, Lilo bit down, but her jaws were so far apart that they could exert only a minimum of force. Although the part of Lilo’s mind that wasn’t already in a blind panic knew that she couldn’t have done the virtually indestructible Stitch any real harm even if she had the teeth of a tiger shark.
Stitch didn’t want to hurt Lilo, or make her do something she didn’t want to. But his urges had returned with even more force than when they had struck him the first time, three days earlier. He could barely even think now; his body acted on its own, desperate to sate the fiery need that engulfed it.
With his lower pair of hands, Stitch grabbed the collar of Lilo’s nightgown and tore the garment open down the middle, exposing Lilo’s chest and stomach. His fingers rubbed, pinched, and squeezed the little girl’s brown nipples as he thrust his upper cock all the way to the back of Lilo’s throat, making her gag violently. His other cock bumped against her chest as he thrust into her mouth again and again.
“Nnnnngh! NNNNGGGGGLLLLLHHH!” Lilo screamed as the alien she thought of as her best friend savagely raped her face.
She beat her fists wildly against Stitch’s torso, desperate to make him release her, to make him stop choking her with his thick, inhuman member. But it made no difference—except to make Stitch grab hold of Lilo’s hands and use them to massage his lower cock as he had done the last time. If Lilo hadn’t been helpless to stop Stitch before, she was now.
“Yes,” Stitch hissed mindlessly. “Yes, Lilo take, Lilo take more…”
But even as Stitch used Lilo’s body to try to assuage his burning need, he knew that what he was doing wasn’t enough. Not this time. He needed something more—to get in farther, to get his whole cocklength into Lilo before he lost his mind completely.
As his capacity for rational thought sank out of sight in the raging ocean of the blue alien’s agonizing need, Stitch used his inhuman strength to pull the helpless girl forward and tilt her head up so that her big, watery eyes were looking up at his face. Then he shoved his upper cock straight down her throat until her nose was against his pubis and the base of his lower member was pressed firmly to her chin.
“GGGGGGLLLLLGGGG!” Lilo screamed, her body wriggling futilely in Stitch’s grip.
Oblivious to Lilo’s distress, Stitch cried “YES!” and began pumping Lilo’s throat. The sensation of the gagging girl’s esophageal muscles working helplessly against the entire length of his cock was bliss.
Lilo had been so worried about Stitch doing what he’d done to her the last time that she had never imagined he might do something even worse. With his thick member filling her throat to bulging, Lilo felt like she was choking and drowning at the same time. And perhaps even more painful was that Stitch didn’t seem to care. He was just using her, using her body.
Stitch fucked Lilo’s throat hard, fast, and deep. His pubis collided with her nose on every thrust, and his lower cock, which he was still making Lilo hold in her hands, struck the girl’s bare chest again and again. He felt pressure building up inside him, even stronger than last time, in his balls and inside his body, and he knew instinctively that the only way to release that pressure was to fuck the helpless girl’s face even harder and faster.
Now, his cock was a blur as it pumped in and out of Lilo’s wide-open mouth. Tears streamed down the girl’s cheeks, and she gurgled and whimpered pitiably as her mouth and throat were raped.
“Yes,” Stitch growled mindlessly as his thick shaft pistoned in Lilo’s throat. “Yes, yes, YES!”
And now Lilo really felt like she was drowning, because Stitch’s thick, hot seed was unleashed in an explosive torrent that filled the small girl’s stomach. At the same time, his other cock fired huge wads of semen that splattered thickly on Lilo’s bare chest, completely coating it in the milky, translucent substance.
The moment his climax ended, Stitch again put his hands on Lilo’s chest and began rubbing his seed into her bare skin and exposed nipples. Obsessively focused on this activity, he didn’t even withdraw his upper cock from the girl’s mouth, instead letting her cough and gag until she expelled his softening member herself. Even as Lilo gasped desperately for air, Stitch did not stop rubbing his cum into her chest until she finally spoke.
“Stitch,” she gasped. “Why? Why did you…why…”
And now Stitch’s mind eased back into his head again, and he was suddenly struck with remorse. He’d hurt Lilo. Again.
“Stitch sorry,” he said, taking his hands off Lilo’s chest and putting his arms around the child, heedless of the mess he’d made of her and was making of himself. “Stitch very sorry.”
Lilo wept for minutes, and Stitch let her. Then, when her tears slowed, he stepped back and looked at her cum-coated, half-naked body.
“Stitch sorry about nightgown, too.”
Lilo said nothing. Now, she just glared at Stitch, skeptical and angry and afraid.
“Will never need to do again,” the blue alien said. “Stitch promise.”
Lilo’s eyebrows lowered. “Never?”
“Never,” Stitch repeated.
Stitch hoped that he was telling Lilo the truth. But even if he was, he knew it was not the whole truth. Because it was at that moment when Stitch came to a terrible realization: that these terrible urges were stronger were stronger than he was. Try as he might to fight them, they would always come back, and they would always win. If he tried to run away, to save Lilo from himself, those powerful needs would drive him right back to her. And if he tried to block them out, they would explode from within him with even greater force, potentially making him do grievous harm to Lilo and maybe others in the process.
No, his only option now was to cooperate with these urges, and to try to find ways to sate them that didn’t involve hurting Lilo. Or, at least, ways that would hurt her less.
But he was going to have to think quickly. Because despite his having just filled Lilo’s stomach and coated her torso with the substantial loads of cum that his body had generated, it was already generating more. And now, his instincts were giving him a different destination for it.
“Lilo not worry,” Stitch said. “Stitch leave Lilo alone now. Stitch sleep somewhere else tonight.”
He walked out the door, closing it behind him. Then he headed for Nani’s room.
