A real doll, designed for adult pleasure, receives an intense oral training. Its realistic mouth opens wide, revealing a pink, inviting cavity. A thick, hard cock presses against its lips, demanding entry. The doll's tongue darts out, licking the precum off the tip before the cock pushes in, filling the doll's mouth completely. The doll's cheeks hollow out as it sucks, slurping and gagging slightly, but never stopping its eager, thorough work.
