No chance.

There is only so much willpower and determination can do. You manage to last five strokes before you explode with a feeble groan. As you flood the condom with more and more cum, you whimper and beg for her forgiveness. She doesn't say anything. She just smiles and closes her eyes, a satisfied sigh coming out of her. When you finally stop, your eyes are closed and you're trying your best not to cry. "Wow! You came longer that you lasted!" Kristi chuckles, still seated comfortably on your crotch.

"I'm sorry. I'm so sorry!" You sniff. "I couldn't hold it back any more."

Kristi chuckles again, but this time there's an edge to it. She leans down and pats your cheek. "Don't think you're getting off that easily," she says, rocking her hips back and forth. You grimace, the pleasure mixing in with the pain of over stimulation. "We need to get your ears checked when we get back," Kristi moans, licking the tip of your nose. "Or maybe after this, you'll finally pay attention when I speak."

Grunting and hissing, you wrack your brain, trying to recall what she said. But all you're getting is the sloshing of your cum on your cock as her walls contract around you and the total pressure keeping you hard. You're also seeing visions of sinks, deserts, and whirlpools. Nothing makes sense at all, but your next orgasm sneaks up on you and your body shakes violently again, making you grunt and snarl in pain.

"Remember now?" Kristi grins, happily absorbing the heat from coming from within her. Panting in agony, you shake your head. She leans in closer still, pressing her body against yours. Blowing softly into your ear, she makes a chill go down your spine. "Tonight, I'm draining your balls, dry."

Oh boy.
