Matthias was woken up by a noise at the door. The frame opened, revealing two shadowy figures. He recognized them immediately - his sister, Joanne, and her friend, Lilly. It seems their sleepover party has been moved to his bedroom.

"And he just takes it?" asked Lilly.

"Yes, look." His sister came up to him and unceremonously grabbed him by the balls, holding pretty tight. Lilly turned the lights on, to see for herself. With the lights on he also got to notice, that both were wearing only a bra and panties.

"Woah, this is hot. Can I try it?"

"Oh yes, that's why I brought you here!"

As Lilly came up to Matt, Joanne gave her a cheeky slap on the ass, they both giggled. He felt her slender hands feel his balls out, get familiar with them. And then, she started to constrict. Matt, while trying to keep silent, noticed Lilly became instantly aroused. His sister noticed it too. She embraced Lilly from behind and slipped her right hand into her panties. As Lilly was nearing climax, her grip tightened. He almost screamed at the end, but managed to keep it inside. The girls were delighted and started kissing over what just happened. His balls were no longer gripped. "Now is my chance".

He stumbled out of bed and ran to the hallway.

"Mom!" he exclaimed. "Mom!"

A tall woman in a sleeping gown emerged from the shadows.

"What is it?"

"Joanne and her girlfriend are torturing me!"

The woman laughed. "You agreed to this, remember? Now be a man and see it through. You're nineteen already, be at least a bit responsible for yourself."

"But mo-"

She slapped him in the face. "Should have not been born a male failure. You're the lowest status creature in this house, get used to it."

"Oh, there you are" said Joanne's voice from behind.

"Yes, he should be sorted out by now. You girls have fun!"

"We will."

Nowhere was safe. There was nothing he could do. And it's true, he brought this on himself. One day, when he was exceptionally horny, he invited his sister to play stripper poker. What he didn't know at the time, is that she was exceptionally good at it, and all his victories were staged. He was completely naked while she still had her underwear on.

"Game over boy, you don't get to peep on me and jerk your pathetic little cock off."

"I want to play again!"

A devilish smile appeared on her face. "Alright, but if I win, I get the ownership over your balls. I get to do whatever I want with them."

And they played. And he lost. His reminiscing was interrupted by the pain again. The two girls held one of his testicles each, and squeezed them while kissing passionately. Eventually, their clothes came off, revealing two amazing, twenty one years old bodies, that in any other circumstance would get him overwhelmingly horny.

"This is amazing" said Lilly. "We're supposed to be scared of them. We're supposed to desire them. What for?! They become slaves the moment you grip their sensitive place. The only thing arousing about men is seeing their submissive desperation."

Joanne gasped with excitement and started pleasuring Lilly. "Finally, someone who gets it. The powerful feeling when you hold a guy by his balls." Her panties started visibly soaking. "But there's more. Want to feel real power? Crush his balls."

Lilly wasn't ready to hear that. "What? He's your brother."

"Exactly! I wanted to do this for so long, please, do it for me. I'm gonna hold your hands to help you crush them flat."

And so they did, two pairs of hands closing in to crush his manhood from the sides. He couldn't hold it anymore, screams were heard all around the mansion, and when his balls finally sploshed in a silent, shameful explosion, the pain only got worse. After completely flattening his balls, the two girls sat down and started masturbating vigorously, overwhelmed with excitement. Soon after, they started to rub his balls with their feet, just to feel it again, how hopelessly castrated he was. Their loud moans heralded the beginning of his slave days.
