Before anything else, Ty wished that Billy and Katie would teleport and switch places with the rest of their family. Instantly, the two children appeared right in front of Ty, while the other family members continued their fucking in the background.
I wish Billy and Katie would merge together from the head, thought Ty. And they’ll continue sinking into each other till they’re connected from around where their navel is.
While he made his wish, Billy and Katie continued their fondling and their French kissing. Somehow they're managing pretty well for an 6 year old and an 8 year old, though Billy had to keep facing up to her older sister while Katie had to keep looking down. They rubbed their tongues together and exchanged saliva within their locked mouths, when suddenly, they found their tongues sticking together.
“Mmrph?”, Billy voiced out, as he and Katie eyed down at their mouths in confusion. No matter how they tried, they couldn't pull their tongues apart. Katie felt the same thing, and she tried pulling her head away, but to her surprise, their lips also refused to budge.
And then, Billy and Katie found their heads suddenly flowing into one another, with the lower parts of their faces mushing together like soft clay, The two tried to pull back, but somehow their heads were being dragged into each other, causing more of their heads to absorb into one another.
Eventually, the children were blinded as their faces completely melded with each other, and their hair also started to vanish, leaving two bald heads. There wasn’t any sign of Billy and Katie struggling for air, and if anything, Ty guessed they were still feeling quite pleasured, especially with his sensitivity wish still affecting them.
Ty could still hear the faint sounds of the children moaning as they continued to used their hands on each other, and their voices were eventually silenced when Billy and Katie’s heads pulled further into each other.
“I-I can’t see!”
Ty recognized Katie’s voice ringing in his head. He wasn't too sure how the family's thought speech worked, but he guessed they'd find it no different to talking through their mouths.
“Katie?”, another voice asked.
“Billy!”, Katie exclaimed. “I can hear you!”
“I can hear you too! Ohhh…”
Bllly’s voice cut off for a moment as Katie squished the head of his penis with two of her fingers.
“Y-your hand,” Billy’s uttered. “It feels really good.”
“ I know-oooohhh…” Billy and Katie shivered as their merged heads started to shrink away and their bodies pulled closer together. Eventually, their heads have completely gone, and the two kids were now fused to each other by the top of their necks. For some reason though, the two found they could still hear things, even though their ears have gone as well.
“I think we have to bend down. I-I think our necks are connected!”, Katie thought out. Apparently, Ty’s sensitivity spell also gave Billy and Katie the ability to have a good sense of their body’s form and shape, as well as their surroundings, even without any eyes. It probably goes with the other family members as well.
Ty could see Billy and Katie’s body struggling to hold their position, and they each shuffled themselves a foot or two back. Each of the kids bent down towards each other (sticking their butts out in the process), and used one hand to support the other’s body, while the other hand went to carelessly masturbating their self.
“Katie, ooohhh….” Billy moaned. “I’m feeling something else!”
“W-what is it?”
“Like…I don’t know, it’s like can feel your...your pee-hole!!”
Katie was startled to hear that. But when she focused, she found she could feel parts of Billy’s body as well as her own, and she could also feel a pleasurable spot coming from her younger brother’s crotch.
“Whoa! And I can feel your wiener!!”, Katie exclaimed. Whatever the other child felt from their other sibling’s body, it wasn’t as strong as feeling their own parts. It was more like a vague glowing sensation, but the feeling was still wonderful enough. Billy cooed as he felt more feeling coming from Katie’s body as well, at the same time that Katie was wiggling her fingers inside of her own vagina.
“I-it’s so weird!” Billy uttered “W-what’s happening to us?”
“I don’t know,” Katie replied. Then she let out something that sounded to Billy like a squeak, as Billy rubbed his own ballsack while fiddling with the base of his penis. The little boy giggled.
“Katie, do you like it?”
“Yeah…”
“Me too…”
The merging continued. The children’s necks had merged completely, and now their shoulders were sticking together.
“Whoa, I-I can’t feel my fingers!” Billy called out. “No…it’s my hands! They’re gone!”
“Mine too!”, exclaimed Katie. The children’s fingers had withdrawn completely into their palms, and their hands became nothing more but rounded stumps at ends of their arms, The arms of Billy and Katie eventually came against each other, and melted together like their torsos, till Billy and Katie both shared a pair of handless arms. Ty laughed as the children flailed the limbs around, apparently not knowing how to control them together.
Eventually though, the limbs began to shorten into their melting shoulders, and completely vanished. The bodies continued to get pulled into each other, with their nipples and chests merging with whatever organs inside, until finally, Billy and Katie’s belly buttons came into contact and merged into one navel.
Ty thought it would end there, but he noticed the kid’s shared body balancing itself out, with Billy’s legs growing longer just a bit while Katie’s legs shortened, till the kids legs stood at the same height as each other.
With that one final touch, the changes stopped. Billy and Katie were now nothing but the lower halves of two bodies merged into one.
From the voices of the kids, Ty could tell the transformation itself wasn’t giving the kids enough pleasure, and now they had no way to touch themselves standing up. They stood in place, and their shared body quivered as liquid dripped from their privates.
“Oooh…Katie, can you t-touch me?”, Billy pleaded. “I can’t touch myself!”
“I can’t! I…we don’t have arms remember?”, said Katie. “Uh…maybe…maybe we can lay down, flip over and use our feet!”
“Oh, okay…”
The kids did just that. Carefully, with Katie guiding her brother, the two kids squatted down and touch their shared belly onto the bedroom carpet. As Billy and Katie changed their position, Ty was momentarily distracted by cries from Susie and Helen. They had just went through another orgasm, and stopped for breath for a few seconds. Helen sat back with a smirk of desire, and moved herself to point her rear end towards her daughter, and after just barely a minute of rest, Susie got to pounding her mother’s backdoor.
Ty heard children’s laughter in his head, and his attention went back to Billy and Katie, who were now lying on their shared back and were trying (not too well) to use their feet to touch each other and themselves. Billy managed to rub the sides of his erect penis with his two soles, while Katie could only slide the back of her feet on the front of her vulva. Though it sounded like she had fun trying to kick Billy’s legs away, and the two kids played around, eventually stretching their legs outwards and wiggling each other’s toes.
Somehow, the sight of that was what sent Ty’s dick ejaculating onto the kids.
Ty reared back with eyes closed, and let his dick throb away while he emptied his semen onto Billy and Katie, with a few spurts hitting the bedroom carpet. The children noticed some gooey liquid splash onto their feet and legs, with a couple of splatters on their belly. They were confused, but were too busy laughing at each other to care.
As Ty’s dick went limp and the throbbing stopped, the teenager let out a long, satisfied breath.
Yeah, I’m a goddamn sicko, he thought. He smiled, and rubbed the end of his flaccid member while looking around his handiwork.
The father and eldest son are now two dildos and a strap-on, the mother's a living plasticky bimbo statue, the youngest kids are glued together into one weird thing with four legs, and the final daughter...
Ty rubbed his chin. Yeah, maybe he'll change Susie into something too. Or maybe he should get Billy and Katie to do something with the rest of their family?
Still hungry, he mused to himself. He prepared for his next wish.
