In a world where bodies are drawn with exaggerated curves and features, a brother and sister find solace in each other's company, their bond deepening into something more than familial. As they lounge together, watching anime, the sister's leg brushes against her brother's, sending a jolt of electricity through them. Later, in the bathroom, the sister catches a glimpse of her brother's cock as he changes, her eyes widening at its size. Their desires intensify, leading to stolen glances, accidental touches, and a growing need for each other that threatens to consume them.
