[Ishimiso] Metal Girl Ie Onanie (Nodo Onanie-hen) [MTL]

A poised businesswoman turns a seemingly ordinary lotion purchase into a private, increasingly intense solo training session with a metal, tentacle-like sex machine. Her generous breasts, broad hips, and rounded ass frame the escalating play as she kneels, sucks on the pump assembly, handles the detachable shaft, and ultimately takes the ribbed device deep from behind while gagged and spread across the floor. Crude English exchanges—from “Finally bought it!?” to “That was a satisfying training session today”—give the monochrome story a knowingly goofy, experimental mood as her careful plans unravel.
