The pain is wonderful

You grab her tits as she begins to squeeze your balls hard, you feel them change shape further and further as the pain gets worse and worse. She kisses you, and begins to make out with you, you've never been more erect.

"If you let me keep squeezing I'll blow you and give you the best orgasm of your life. If they don't pop, I'll be yours baby." She coaxes you as you simply agree. You want her and you're willing to endure the pain.

She continues to squeeze as hard as she can, your balls suffering from the pain as you hurl over, feeling her beautiful tits in your hands. You kiss her as she quite literally tries to castrate you.
