Whoa! The night I first slipped this in before “turning in” for the night, I knew I’d found a new friend! Lots of fun just getting it in, then turn on the “motor” and we’re ready to dream of ourselves as Engineer of a Steam Locomotive, straddling the engine all the way to Chicago! (from L.A.) Well, perhaps not that far – around 4:00 a.m. the engine starts to tire. After all, it’s powered by only one of those tiny “N” batteries and doesn’t have quite the staying power I’d have wished. But aside from that! And those bumps on the bottom keep one aware that more than just a couple of spots are intended to be pleasured by this device, and pleasure they do!
