He strokes himself slowly, savoring every sensation, his imagination running wild with taboo scenarios. The closet door creaks open, revealing a surprised sibling who catches him mid-stroke. Embarrassed, he tries to hide his erection, but the sight of his sister's shock and curiosity only fuels his desire, leading to an unexpected encounter that neither of them will ever forget.
