In the dimly lit dungeon, she's collared and cuffed, her body trembling in anticipation. The machine roars to life, its metal dildo spearing her mouth, invading her throat, forcing her to gag and retch. Her lover, a dominant spectator, masturbates, his hand slick with spit and pre-cum. He moves in, his cock replacing the machine, filling her mouth, fucking her face roughly. She's a whore, a slut, existing only for their pleasure, her body marked by their lust, her cries muffled by their flesh.
