Do you like? See how hard it is, it excites me to see you slam those balls!
Give me 50 strokes
Do you want to see my ass too? It will cost you you know ...
Take another shoelace and attach it to the first one, so that it dangles between your legs.
Take the 2kg weight and attach it to the string let it dangle, between your knees.
Now move it, you have to swing it, it must go very high, at least up to your balls, and then fall back.
Do it 15 times, and maybe i show you my perfect ass.
