My girlfriend is an insatiable pervert—not just a little kinky, but constantly horny no matter where we are. She'll suddenly get turned on and aggressively come onto me at any moment. I experienced this during a date. In the elevator lobby, she begged me to turn on her vibrator. Shaking from the vibrations, she stuffed my huge cock deep into her mouth and started sucking me wildly, making loud slurping sounds. Realizing we couldn't keep going there, I dragged her to a secluded stairwell landing. But even there, her lust didn't stop. While leaking piss everywhere, she kept having dirty sex with me over and over, cumming repeatedly like a maniac. After one intense round after another, I finally reached my limit. Trembling intensely, I shot a massive load of hot cum deep inside her pussy in a thick creampie.
