They are saggy, especially as young as she is, but that would be a good excuse to punish them, slapping the undersides and outsides to make them fly. And then whipping her nipples until she came.
I suppose to see the application of the stripes to her saggies you have to pay for the whole video. I like the gentle tit-whipping, which likely gets harder later on. I would very much like to slap those and make them fly.
