Squeezing Them!

She sits down on the floor before cracking her fingers and carefully peeling your flatted balls off of the floor. You don't understand why she is being so gentle given what she has just done, though you know better than to ask.

She leans down and plants a wet kiss on each of your balls, first left then right. For what feels like hours but is more likely just a minute or two, you feel her fingers exploring your damaged organs gently.

She finds spots you yourself didn't feel were there, where one of your balls are softer and weaker, and probes them cruelly with her fingers while giggling.

After a while it clicks in her mind; It's her toeprints!

5 soft spots of varying sizes on each nut, numbering 10 in total. It seems you were right when you thought you could feel the damage when she stepped off.

"Woah...." she whispers to herself as she pulls your swollen balls further towards her, before softly placing one of her feet back on your balls. Her toes slot neatly into place.

However it seems this is nothing more than a novelty to her as she quickly resumes squeezing, this time much more viciously.

As she twists and squeezes your near-broken nuts, you can feel cracks and tears start to form inside them. You think she feels it too, as she ceases her attacks before pulling them to the base of your sack, making them prominent.

She then softly, almost caringly, whispers a "goodbye..." herself with that too familiar sweet smile.

Before you know it, her fingers are pressing deep into the soft spots on top of your balls and her thumbs are making new ones on the backs of them.

She leans in really close and continues mauling your orbs, so close you can feel her heavy breath on them. "That bitch" you think to yourself, "She's getting off on this".

It doesn't take much longer before they collapse in her soft yet firm grip. You feel her bury her face in your now pulped sack and inhale while shuddering; Your sister just came while she broke your balls.

You hate yourself for it, but as you pass out from the pain a part of you is happy she at least got some pleasure from it. Happy that even in their final moments your balls could be of use to somebody.
