Mercy, a petite yet fierce force, mounts the fuck machine, her heart pounding in anticipation. The machine, a towering beast of steel and silicone, looms before her, its glistening member twitching with simulated life. She positions herself, feeling the cool air on her exposed, dripping cunt. With a flick of a switch, the machine roars to life, its relentless rhythm driving its cock into Mercy's depths. She gasps, her body tensing as she's filled completely, her walls stretching to accommodate the machine's girth. She rides it, her hips bucking, her body covered in a sheen of sweat as she chases her orgasm, the machine's unyielding pace pushing her closer and closer to the edge.
