The leotards of the girls in the gymnastics club are so hot! They dig into her crotch and show her vertical lines! It's so obscene that I secretly told her about it, but the moment she realized how embarrassed she was, she ended up with even more erotic stains, so in a way, it was counterproductive advice! Then her sense of shame got out of control, and she finally went into a super erotic mode, reaching for my crotch!
