Chapter 7
It was Monday afternoon, and Nani was emptying the contents of the full-to-heaping laundry hamper into a big pile on the floor in front of the washer and dryer so she could separate the whites, colors, and delicates. They had a lot more delicates now than they’d used to, because Stitch had told Nani to buy sexy nighties and underwear for herself and Lilo to wear in Stitch’s videos. The money coming in from said videos made lingerie—and many other things—a lot more affordable than before.
Stitch had cameras all over the house now, all of them constantly recording so that Stitch could fuck the girls whenever and wherever the urge struck him, without having to worry about turning cameras on and off or moving them around. He would edit the recordings at the end of the day and upload all the sex scenes to his paysite.
This meant that the girls needed, not only to be ready for sex at all times, but also to be sexily dressed at all times, because Stitch could turn any moment into a vignette for his growing porn-video library. Today, Nani was wearing a tan crop top and jeans shorts cut high enough to reveal the bottom inch of her ass-curve. Beneath the top, she had on a lacy black pushup bra that only just fit her now very large breasts, squeezing them upward so that they looked positively enormous under the top.
Stitch emerged from Lilo’s bedroom and approached her.
“Nani take off clothes,” he said. “Lie down on laundry.”
There had been a time, only weeks ago now, when Nani would have been appalled by that command. Now, she felt herself beginning to become aroused. She didn’t mind being ordered around as long as the end result was Stitch plunging those two thick cocks of his into her hungry holes.
Nani took off the crop top, exposing the lacy pushup bra, which she unhooked to release her huge breasts. Then she pushed down the shorts to reveal a pair of crotchless panties that were lacy and black like the bra.
While Nani undressed (leaving the crotchless panties on), Stitch, his twin cocks already hard and bobbing in the air, spread out the pile of dirty laundry for Nani to lie down on. When she did, he used all four of his hands to fondle her big tits, squeezing and kneading with two of them while the other two gently pinched and pulled her dark nipples until they stood out, thick and dark and hard and proud, from the tan surface of her tits. Nani was already panting with desire; no human man could pleasure her breasts this way.
Nani raised her legs in the air, and Stitch got on top of her, his head at the level of her belly. Then, with two of his hands, he lined up his cocks with Nani’s two entrances, and he slowly pushed in.
“Ahhhhhhh,” Nani moaned.
Stitch had fed Nani and Lilo a big cumload that morning, and then he’d fucked Nani in her room a couple of hours later. So now he could take his time, slow-fucking Nani as she gasped and moaned beneath him, his two thick shafts pleasuring her deep inside.
“Oh, yes,” Nani moaned. “Fuck me, Stitch…Never stop fucking me…”
They fucked and fucked and fucked, Stitch pumping her at that same slow pace, until eventually Nani was so out-of-her-mind horny that she begged him to go faster. Stitch gradually sped up until he was pounding Nani’s holes hard and fast, and Nani was crying out “Ah! Ah! Ah!” in time with his rapid thrusts.
She came, screaming wild and loud and long, and her pussy and asshole gripped Stitch’s cocks so hard that it took his superhuman strength to thrust deep into her one last time before he unleash a huge flood of his seed inside her, filling her womb and her bowels so full that her whole body spasmed wildly with the pleasure of it.
Nani was just cleaning up when she heard the front door open and then Lilo shouting “I’m home!” This was no surprise, as it had been part of Stitch’s plan for Lilo to go to school one last time, and this was the hour when Lilo normally got home.
Outside, from behind some fronded shrubs, Mertle Edmonds watched Lilo go into her house. Then, remaining concealed, Mertle sneaked around to the back of the house. She found a good hiding spot, settled in, and looked at her phone to make sure that its camera app was open.
Mertle could scarcely believe that Lilo, who had been a freak to begin with, was still coming to school despite her bizarre condition. There was no way a girl their age should have boobs. And she certainly shouldn’t be going out in public where decent people could see them.
Deep down, Mertle was intensely envious. But not being one for introspection, she interpreted the feeling as righteous anger at a girl who wasn’t properly ashamed of her weird body. When Mertle had mocked Lilo for it on the school playground, Lilo hadn’t even had the decency to run away crying; instead, she said she was proud of her new figure and that she’d even taken to sunbathing topless in her back yard every day after school.
The stupid girl hadn’t even realized that she had handed Mertle the perfect opportunity to visit some well-deserved humiliation on her. Sharing a few pics of the half-naked freak and her bare freak-boobs with the other girls at school would do the trick.
What Mertle didn’t know was that Lilo had dropped this little hint on purpose, specifically to lure Mertle to the very place where she was now hiding. Nor did Mertle know that someone was lurking right behind her. At least, not until three hands grabbed her and lifted her off the ground, while a fourth hand muffled her screams.
***
Moments later, Nani opened the back door for Stitch while he carried Mertle into the house. The girl was screaming and screeching, but Stitch’s hand was tight over her mouth and kept her from being anywhere near as loud as she would have been. Likewise, Mertle was struggling with all her strength, but said strength was nothing compared to Stitch’s, so her desperate efforts to break free of his grip were reduced to feeble, useless wriggling.
Lilo, Nani, and Stitch had prepared for this moment. As soon as Stitch brought Mertle to the middle of the living room floor (covered in one of several plastic sheets they now owned for this purpose), Nani took a pair of pink bondage handcuffs that Stitch had ordered online and cuffed Mertle’s wrists together behind her back. Likewise, Lilo cuffed Mertle’s ankles together. Then Nani took Mertle’s glasses off and put them on the kitchen counter.
Now with three of his hands free, Stitch ripped off Mertle’s green T-shirt and blue shorts, leaving her in just her very new-looking baby-blue panties and increasing even further the volume of the girl’s muffled screams. The redheaded girl had essentially the same chubby figure that Lilo had, including the little pre-tits Lilo had sported before Stitch began growing them into adult-size breasts.
Stitched pushed Mertle down into a kneeling position. Seeing Mertle stripped and on her knees like this gave Lilo a certain sense of…well, she wasn’t sure what it was called, but it felt good and kind of bad at the same time. And that feeling grew stronger when she thought about what was going to happen next.
“Mertle be quiet now,” Stitch said in the girl’s ear. “If Mertle keep screaming, bad thing happen.”
Lilo hadn’t been sure how they were going to get Mertle to do the things Stitch needed her to do—at least, not without Mertle telling her parents or the police. But as they discussed their plan the previous evening, Nani had seemed to think there was a way to control her.
“Don’t worry,” she’d said. “I know what kind of girl Mertle is.” Her nose wrinkling, Nani added, “She’s vain, like Amelia from my class.” From the way Nani had said Amelia, Lilo guessed that Amelia had once been Nani’s Mertle.
So now, Nani stepped in front of the chubby, bound girl and said, “Mertle, you do whatever Stitch wants. Otherwise-” Nani pointed to the various cameras around the room “-everyone is going to see your chubby little body, naked and chained.”
Mertle’s eyes squeezed shut, but the girl immediately fell silent. Nothing, Nani knew, scared a girl who thrived on humiliating others like the prospect of being humiliated herself.
“Good,” Stitch said.
He released his hand from Mertle’s mouth. When the girl remained silent, Stitch repeated, “Good.”
Stitch’s cocks were starting to get hard. Lilo and Nani silently dropped to their knees on either side of Mertle; then each sister took hold of one of Stitch’s shafts and licked and tongued it until it was fully hard.
“Good, good girls,” Stitch rasped.
The terrified Mertle opened her eyes, not sure what Stitch was talking about. Then she saw that both Lilo and her sister had a thick, black, fleshy cylinder in her hand, and Mertle only had to look straight ahead to see that those cylinders were sprouting from Stitch’s groin.
“What…?” she gasped, unable to raise her voice to more than a whisper.
Mertle’s parents had kept her ignorant about sex, believing that there was no reason why a seven-year-old needed to know about such things. What was more, Mertle was an only child, and her father spent much more time away on business than he did at home, so she’d never so much as caught an accidental glimpse of a penis. All she had ever seen were a few anatomy pictures in library books. At the time, she’d quickly put those books back on the shelf before anyone could catch her looking at them.
So Mertle had no idea whether it was possible for someone to have two penises. She wasn’t even sure what penises were for. But before these thoughts could even finish their fleeting journey through her frightened brain, Stitch was putting the end of one of these cocks to her lips.
“Open wide, now,” he said.
That was the very last thing Mertle wanted to do. She shook her head rapidly, her lips pursed tightly.
Then Stitch took hold of her head, holding it in place with his two upper hands while the lower ones pried open her jaw. Then he pushed his cockhead in.
“NNNNNNN!” Mertle screamed through her wide-open, stuffed-full mouth. At the same time, she bit down as hard as she could on the thick, fleshy invader. But that didn’t help at all.
“Mertle swallow!” Stitch shouted. Then he pushed with his hips as he pulled Mertle’s head and torso toward him, angling her head and neck such that he could shove his cock straight down the redheaded girl’s throat.
“GGGGGGLLLLGGG!” Mertle screamed from her full throat. “GGGGLLLLGGGG!”
As Mertle gagged helplessly, Stitch started fucking the girl’s face. Nani, meanwhile, used both her hands to stroke Stitch’s lower cock while keeping its head aimed at Mertle’s chest.
Lilo wanted to contribute, too, so she got down on all fours and lowered her head to just above the floor so that she could lick Stitch’s heavy balls. She wanted to see what Stitch was doing to Mertle, but she figured she could watch the video later. For now, she was content to hear Mertle gag and choke and gurgle as Stitch raped her throat. In retrospect, it made Lilo appreciate how much gentler Stitch had been with her the first time he’d fed her his cock.
The excitement of throat-fucking a new girl soon had Stitch pumping Mertle’s face at full speed. Nani’s hands worked as fast as they could on Stitch’s lower shaft, and Lilo tongued his balls fervently, wanting him to cum, to shoot his huge load down the helpless Mertle’s throat.
“HRRRAAAAAHHH!” Stitch cried, and Lilo quickly sat up to watch his cock pulsing inside Mertle’s throat as he shot his load. Lilo was treated to the bonus of seeing Stitch’s cum flowing from the girl’s nose as the girl half-drowned in her rapist’s seed. At the same time, Stitch’s other cock was hosing the child’s torso with thick, translucent semen, and Lilo gasped with joy as she watched Mertle’s cum-shiny stomach expand.
Mertle’s already chubby belly soon bulged obscenely as it filled and filled with Stitch’s thick seed, even while Stitch continued to coat its exterior with his other massive load. Lilo found perverse pleasure in watching the girl struggle and gag helplessly, her arms jerking uselessly against their chains and the muscles of her bulging throat working in a futile effort to expel the invading cock and all the seed it was raping into her stomach.
By the time Stitch was finished cumming, Mertle’s belly was so swollen that she looked about ten months pregnant. Satisfied, the panting Stitch wiped his brow, then pulled his cum-slicked cock from little Mertle’s throat.
Immediately, Mertle gagged loudly, then began vomiting up the contents of her distended stomach onto the plastic sheet beneath her. She continued this for nearly a minute, spewing pint after pint of thick white seed until she was kneeling in a wide pool of it.
When Mertle finally finished and collapsed sideways into the pool of cum, gasping for air, Stitch looked down at the messy girl and shook his head.
“No no no,” he said. “That no good. Mertle must keep cum inside. Now must do all over again.”
“Wh- What?” Mertle managed, her voice wet and thick.
And then Stitch grabbed Mertle’s head and pulled her back up onto her knees.
“No! NOOOOO!” Mertle screamed, and then she couldn’t scream anymore because Stitch had forced her mouth open and rammed his cockhead in.
He wasn’t as erect as he’d been before, so he simply used his upper cockhead to muffle Mertle’s screeching while Lilo and Nani again attended to his lower cock, greedily licking off and swallowing the shiny cum that coated it.
Soon, he was fully hard again, so he shoved his cock back down the struggling, gagging Mertle’s throat. This time, Mertle’s oral rape took much longer, as Stitch needed extensive stimulation to build up a full load again. Lilo and Nani switched roles, with the older sister tonguing Stitch’s black ballsac while Lilo masturbated his lower cock. This enabled Lilo to actually see the action, and even though it went on for a long time, she never tired of watching the tears stream down Mertle’s face as Stitch pumped and pumped and pumped the helpless girl’s mouth and throat.
After Stitch finally blew his load straight into Mertle’s stomach and another load onto her torso, he spoke to the shiny-wet, bloated girl before pulling his cock from her throat.
“Remember, keep cum inside. Otherwise, we do again and again until you do right.”
Stitch’s upper cock was shiny and dripped thickly with seed when he pulled it out of Mertle’s mouth. The girl’s stomach was as utterly full as it had been the last time, but although it was a struggle, Mertle managed to keep down Stitch’s prodigious cumload. She lay there helplessly on her back in the shallow pool of semen, whimpering from her painful fullness, as Stitch, Nani, and Lilo rubbed and rubbed Stitch’s cum into Mertle’s chubby little pre-tits.
“Just wait, Mertle,” Lilo found herself saying. “Soon your tits will be as big as mine. Maybe even bigger.”
Mertle had no reply. Speaking required thinking, and right now, she wasn’t capable of that. All she could do was lie there for minute after minute, silently pleading for the ache in her distended stomach to go away as her tormentors kept rubbing more seed into her chest, even scooping some up from the floor to continue the process when the girl was dry. Of course, the semen on her body might have lasted longer if Lilo and Nani hadn’t licked so much of it off her neck and stomach while they massaged her chest.
Finally, at some point, Mertle’s body had absorbed enough of her bellyful of semen that Mertle was no longer in pain. And then, not long after that, her three captors stopped their relentless chest-massage and let her lie there on the floor in peace, albeit still cuffed.
Shooting two full loads onto and into Mertle had freed Stitch from his inhuman lust for what would probably be several hours. But given the way Lilo and Nani had been licking up as much of his cum as they could get away with, it was clear what they needed, and that they needed it now. He would have to get his lust back again.
“Lilo, Nani,” he said, “get Stitch hard. Stitch will feed.”
As the dazed Mertle watched, unbelieving, the two Pelekai sisters stripped off their clothes. And once they were naked, they eagerly sucked and then swallowed Stitch’s cocks like famished calves at the teat.
