In the quiet of the night, step-siblings x and y can no longer resist their magnetic pull. They meet in the dimly lit hallway, their hearts pounding in sync. x, the elder, takes the lead, pressing y against the wall, their bodies flush. y gasps as x's skilled hands roam, igniting sparks where they touch. They stumble to x's room, their clothes falling away, revealing the evidence of their desire. y tentatively reaches out, wrapping their fingers around x's throbbing cock, while x's thumb circles y's clit, making them both groan. They fall onto the bed, their bodies entwined, lost in their forbidden passion.
