While a schoolgirl is home alone babysitting, a delivery man suddenly arrives at her doorstep. But he's no ordinary courier—he's a violent intruder! Trembling in shock and fear, the girl is forcibly restrained. He's thin, weighs only around 30 kilograms, and looks almost childlike—but the rigid, throbbing cock thrust deep inside her shatters her spirit. Convulsing and writhing in agony, she eventually reaches a shattering climax. Treated like a sex slave, she gurgles, screams, and cries out in pain. This is her own home—how did it come to this? She wants to escape, but her body won't obey. What fate awaits this helpless schoolgirl?
