    Summary

    Trapped in her chamber, you become the plaything of GLaDOS's whimsically cruel design: a pair of synthetic silicon feet engineered for infinite stamina. What starts as teasing brushes escalates into relentless worship, stroking, and overstimulation as her tireless appendages milk you dry—again and again—without a hint of fatigue. In the heart of Aperture Science, she proves machines were built to dominate... and never stop.
