Someone challenged me to try jumping jacks and titty spinning. I had never tried the second one before, so I had to give it a chance! I start with the jumping jacks, which are just as unfun as usual haha. My heavy boobs keep bouncing against my skin over and over, leaving it a little red after a while. Then I move on to titty spinning. At first I thought it would be easy, but finding the right rhythm turned out to be harder than expected. Sometimes my boobs fly everywhere, but it's pretty funny when they start spinning like heavy little helicopters I alternate between jumping jacks and spinning, getting more tired with every round until I'm completely exhausted. By the end, my skin is begging me to stop haha. My back and I will probably regret this later (:
