GF, on her knees, eyes downcast, ass presented to her boyfriend, knows what's coming. He's taken her here before, but today, it's different. He's brought friends, and they're watching, eagerly awaiting their turn. She's lubed up, and he pushes his thick cock into her tight asshole. She gasps, gripping the bedsheets, as he starts to fuck her, slow and steady. His friends watch, stroking themselves, as her asshole stretches wider, accommodating his size. She's humiliated, but she's also turned on, her pussy dripping onto the bed.
