Erotic mp3. Have you ever wanted to devolve into a big muscular caveman? Then stroke your cock and feel it as you start to forget who you are while your body transforms and experiences muscle growth until all that is left is big, hairy Neanderthal muscle relying on instinct... and yet also knowing he needs to obey Coach Josh to keep safe in today's world. Once you cum, you'll return to normal - but you'll be left with the desire to be a big furry beast of a muscle man, working out for Coach Josh, loving hairy chests and facial hair, and otherwise wanting to get as close to that fantasy of being a muscle beast man as you can in real life. If you like this, be sure to search for the Muscle Mesmerizer's non-erotic files to work out for Coach, dumb down, & more!
