In the dimly lit room, the Autoplacer hums softly, its mechanical arms poised and ready. The user, unseen and unidentified, has retreated to the shadows, their breath ragged with anticipation. The machine comes to life, its arms moving in a dance of precision and purpose. It strokes, it teases, it plunges, all with an uncanny human-like touch. The user's body responds, their moans echoing in the empty room. The Autoplacer, unyielding and unjudging, brings them to the brink, again and again, before finally granting release.
