My stepsister's pleading eyes meet mine as I push her against the wall, her legs wrapping around me. "Please, don't cum inside me," she whispers, but I'm too far gone in our taboo passion. I thrust into her, her pussy gripping me tightly as I fuck her hard and deep. She moans, her nails digging into my back, her body betraying her words. I can feel my orgasm building, and I ignore her pleas, filling her with my hot cum. She gasps, her own orgasm ripping through her as my cock pulses inside her, leaving her with a creamy pussy that drips onto her thighs.
