The rhythmic hum of the machine pitched upward, a digital whine that signaled a shift in programming. The suction cups clamped tight around Violet’s areolas suddenly contracted, pulling her nipples deep into the plastic tunnels with a ferocity that bordered on violent. Her back arched violently, a bow of straining muscle and glistening skin, as the automated tugging began in earnest. It wasn’t a gentle pull anymore; it was a relentless, milking rhythm that dragged at the very root of her breast tissue.

Violet gasped, the sound wet and broken around Seokjin’s thick shaft as he pistoned into her mouth. Her fingers clawed at the duvet, knuckles white, as the machine forced her body to react to the stimulation. Hobi, buried to the hilt in her pussy, groaned at the sudden clenching of her inner walls, her body’s automatic response to the torture on her chest translating into a vice-like grip on his cock.
