"Liar," I murmured, my thumb sinking another knuckle-deep into her ass, stretching her tight ring. "Your pussy's dripping, Julie." My free hand gripped her throat, forcing her to look at me. "You love this, don't you? Being fucked like a filthy slut in a public parking lot?"
"Mmm—yes—!" she cried, her eyes rolling back as I pushed deeper, my thumb breaching her asshole in slow, deliberate increments. "It's so wrong—!" Her hips rolled faster, grinding her pussy against my cock as she took more of my thumb in her ass. "But I love it—!"
I chuckled, the sound dark and satisfied, as I twisted my thumb inside her, stretching her tight hole. "That's because you are a filthy slut," I growled, my cock throbbing inside her pussy as she clenched around me. "You crave being used like this."
