Heavy rain suddenly halts all train lines across the capital region... My niece, a schoolgirl, arrives at my place drenched and soaked. The shirt I lend her is too big, constantly slipping to reveal glimpses of her breasts and panties. Her innocent behavior leaves me flustered. She presses her body against me—her breasts rubbing against me—half playful, half unconscious. I can't resist her pure, guileless charm, and my restraint shatters completely. Soon, my uncle's bare cock plunges deep into my little niece. A secret relationship no one can know... In this forbidden moment, I'm utterly aroused.
