I don't have a clue how it works, and frankly I don't care, but somehow, those wily Cal Exotics bastards have devised a way to make this blow-up simulacrum of Penthouse Pet Linn Thomas moan, gasp and talk dirty ? when penetrated. I shit you not, upon insertion of ? well, what have you into the Futurotic? pussy or ass, the damn doll starts in with the oohing and ahhing. Color me amazed. (Of course, the talking feature can be turned off, at user's discretion.) Includes talc and bullet vibe.
