A sexual act performed by two lucky individuals on a middle aged, indian man, with glasses and no personality, whose knees are knobby AF. An up and coming sex position, it promises to make your day beautiful and filthy wet. Forget a wet female part, this is the real fucking deal. Knee sucking is the next big thing, and will fucking rock. So lets fucking get started on SMK.
