Wellies are another name for rainboots.
Wellies fetish is the love of the chunky soles, stiff rubber, the squeaky sounds the boots make and the way they make your soles stink after wearing them with no socks.

You can even fill wellies with sloppy things such as pudding and enjoy the messy sounds it makes. I love wellies and I hope you do too. Jerk your cock as I tease you with my stinky soles and sexy rubber boots.
