Moderately hard

"Let's start with a moderate squeeze, so i can judge what it's like." You tell her.

"That's smart. I don't wanna crush them, at least not yet..." She jokes before suddenly clenching her fist around your balls. As she does, you feel an intense pain radiating from your balls and through your body. "Oh damn..." You groan, doubling over into her grip.

She smirks. "I guess that "Moderate" squeeze is already a lot for you, huh?"

"Mmh, yeah... It's so tight. This is only moderate strength?" You question, surprised by her insane grip.

"Yeah, i'm only squeezing at like half strength." She smirks, maintaining her tight squeeze.

This shocks you. It hurts this much, yet it's only half of her strength. You try to imagine what a full strength squeeze would feel like, but the intense pain coursing through your body immediately snaps you back to reality.
