So this challenge is all about entertainment! You'll need some jingle bells and string or rope or clamps or rubber bands or something to attach them to yourself - preferably onto your nipples, though I'm always of the opinion more jingle bells the better for tasks.
So step one - dress the part, get all holiday fetished up! Get your red and white striped rope out, or you know, just be naked with a Santa hat (complete with jingle bell), you do you.
Step two - choose some Christmas music. Find a nice youtube video or turn on a randomized Christmas music channel.
Step three - shake to the beat! Don't be discouraged if you can't get it the first time, try try again! Bounce, shimmy, shake, jiggle, sway, etc.
Step four - you got the hang of the rhythm? Great! Now mix it's time to mix it up! Become a human drum machine by slapping your tits, ass, cunt, and tummy to the rhythm.
Set a time limit or a song limit or just go until you get tired! And just think what a fun party trick this would make!
