Pyotr's restless night results in an ungodly erection that tents his sheets. His sister, Katerina, overhears his muffled moans and curiosity piqued, tiptoes in to investigate. Catching him mid-dream, she finds him buck-naked, his thick cock twitching. Her eyes widen, taking in his size, her heart pounding in her chest. She can't help but imagine how that monster would fill her own needy pussy.
