The woman lies on the bed, her legs spread wide, her chest heaving with anticipation. In front of her, a mechanical dildo whirs to life, its steel shaft glistening with lube. She reaches out, her fingers brushing against the cold metal, before it slips between her lips. She moans as the dildo slides deeper, pushing down her throat, making her gag. But she doesn't stop; she wants this, needs this. The machine pumps in and out, faster and faster, as she struggles to keep up.
