Ben And His Sister Samantha.

25 year old Ben looked at the page again, and again, he'd found it while mindlessly scrolling on the dark web but there it was in black and white, an illigal move called the Caveman Manuver, able to turn even the most intelligent of people into nothing more than mindless sex drived primals.

"This...this is rediculous, its obviously some kind of fake article, its gotta be..right?" He said to himself, there was a picture attachment to the article, he clicked on it, the picture was a diagram of a human neck, with little circles to the exact spot on the back of the neck you'd need to specifically hit to render your chosen subject an idiot forever.

"This is stupid" he said, but even as he said that, he couldn't help but memorise the technique shown, the spot on the jeck where youd need to hit, he'd be able to do it easily.

But if this was real, who would he even do this to?.. who could he pick that wouldn't raise any questions?.. who would even be cruel enough to deserve this kind of...treatment?

Suddenly his door burst open and his 32 year old busty sister Samantha strutted in.

"I'm taking your ps5, mine broke, and if you argue with me i swear to god I'll report you for ****!" She yelled at him, she had been threatening him that for years.

Samantha had no job, nor did she ever want one, she was perfectly happy stealing the money from mom and dad, who were completely exasperated with her.

Whenever she got caught stealing or scamming people it either devolved into a screaming or crying display, sometimes she'd attempt to seduce her way out of it, more often then not it worked.

Ben had always had an attraction to his older sister, her tits alone were the subject of many of his teenage dreams, secretly he had wanted her for ages, could this move accomplish that?..

No, it was permanent, she'd be a permanent cavewoman, he couldn't do that to her.

"Umm..no?..your not having my ps5, you'll just break it" he said.

"Listen to me you little shit, i always get what i want, im taking this whether you like it or not" she said, suddenly rushing towards it, nearly ripping it from its plug, and running off with it yelling "looser!"

Ben was angry but took a breath, there was no point in loosing with her, she'd just end up crying her way out or running to mom and dad.

Instead he just calmly went back to the dark web, memorising exactly which area of the neck to hit, and writing it down...
