Body Foundation Neo Vol.3 Who's the JAV actress in this video? Amateur? Name revealed!

Body foundation, also known as "body fuan," is an undergarment worn not only beneath leotards used in ballet and rhythmic gymnastics but also under dresses. It serves multiple purposes such as preventing sheer visibility through thin leotards, protecting costumes from sweat, and enhancing body shaping. Designed with highly elastic, soft-textured fabric, it fits snugly against the skin like a "second skin," blending naturally with the body. Though rarely seen in everyday life, for leotard enthusiasts, it opens the door to a deeper, more intricate world. Take time to appreciate its beauty and functionality, and discover its unique appeal.
