CBT

"C is for cock and ball ****," Kara says, delight in her voice. "Or maybe it'll be C for castration..."

She kneels down, taking your balls in one hand. "Shall I just crush them? If I press hard enough maybe I could turn your rocks into diamonds."

She taps the little finger of her other hand against one of your balls, but a tap from this Supergirl is like anyone else hitting it with a baseball bat. You squirm and scream as she maintains her grip on them and continues tapping them 'lightly', alternating between them. Your balls throb with pain, as you writhe on the floor, wondering if she'll ever stop.

Finally she gets bored of your pain. "Your poor bruised balls, maybe you'd prefer my tongue on your cock." You rest for a second, glad of your break, but then she's flicking her tongue down the length of your shaft, giving you a literal tongue-whipping, and you're back to screaming and squirming and begging her to stop. She doesn't listen.

Finally she lets go of your balls, and stands up. "I think I've given you enough punishment down there, maybe I should cool you down." She puckers her lips and begins to blow, cooling down your genitals. At first it's pleasant, helping to ease the pain, but then it gets uncomfortably cold. You clench your teeth with agony as she stops and looks down. "Look at your frozen cock," she says, "a blow from me's got it really hard, and your poor balls, I've left them all blue, but don't worry, I know how to warm you up."

Her eyes glow red and then your frozen genitals are heated up, thawing then boiling, your balls and cock feeling like they're on fire.

"Stop screaming, you've felt nothing yet," she says. "We've got lots more letters to get through. Time for D..."
