"The Moonlighter"

Just over a kilogram of polished stainless steel, 4 centimetres across at its widest. "The Moonlighter" is the heavy end of Satisfyer's steel range, and the width is the first thing to think about.

Both ends can be used and each one is a different size, so you can start with the narrower end and see how it goes. The shaft is smooth the whole way along, with no beads or ridges, so the feeling stays steady rather than rhythmic. The mass does the pressing for you, and your wrist stays out of it.

Steel takes temperature well, so stand it in warm water or leave it in the fridge for a few minutes before you start. Use plenty of water-based lubricant and rock it slowly rather than thrusting. It's rated IPX7 waterproof. This isn't a first steel toy, though. That much width and weight is a lot to start on. Satisfyer covers it for 15 years.
