The peculiar patient, her eyes darting nervously around the Analtreat Asylum's 'nuthouse', knows what's coming. She's heard the whispers, seen the others return, their asses sore, their faces flushed. The nurse, her latex gloves snapping into place, approaches. She's a stranger, her face impassive, her intentions clear. The cutie's ass is exposed, her cheeks spread wide. The nurse's fingers, slick and cool, trace her asshole, making her gasp. A thick, meaty strap-on is brought out, its tip glistening. The cutie's breath hitches as it presses against her virgin hole, then pushes in, stretching her, filling her completely. She cries out, her voice echoing, as the nurse begins to thrust, her hips moving like a machine, giving the cutie her first, hard, 'ass to mouth' lesson in the strange, kinky world of Analtreat.
