I'm sure Jeanne's rear in motion would be a captivating sight!
I still remember one of my female classmates. We had an excursion to a pool complex with a waterslide and for a couple of runs I was in the queue directly behind her. Apart from her leopard-print one piece with a deliciously-low back which looked fabulous from any distance, my vantage point also allowed me to notice how precisely the wet fabric clung to her cheeks and how they wobbled as she walked barefoot along the concrete path and ascended the stairs to the top of the slide. A memorable highlight.
Ah, yes, jiggling is always noticeable and frequently quite pleasant to observe! My own eyes amaze me for their ability to identify unrestrained breasts beneath clothing, for example.
Another one from my school days was the sports class where we tackled the rock-climbing wall of the school gymnasium. A different female classmate really got the shakes as it was her turn to climb and she got towards the top. All eyes were upon her, not just out of concern for her predicament.
And, naturally, Jeanne's graceful movements are also delightful. :-)
