I gripped Julie's hips even tighter, my fingers digging into her flesh as I pounded into her with renewed vigor. The sound of our flesh slapping together filled the room, a raw, primal rhythm that drove us both wild.
"Fuck, Julie, I'm close. Your ass feels so fucking good," I groaned, my voice strained with the effort of holding back my climax. "I'm going to fill your ass with my cum. Are you ready for it?"
Julie looked back at me, her eyes filled with a mix of pleasure and desperation. "Yes, Jack! Fill me up! I want to feel your hot cum deep in my ass!" she cried out, her body shaking with anticipation.
Jessica watched in awe, her breath coming in short, excited gasps as she took in the intense, erotic scene unfolding before her.
