A 50-year-old beautiful mature woman is made to wear ultra-thin, no-bra clothing under the guise of close-contact yoga instruction, told that "underwear obstructs lymphatic flow." During intense aerobic exercise, her sweat-drenched nipples rub against the fabric, becoming rock-hard and erect! "Just from being rubbed that much, they've swollen this much..." After returning home, she plays with her long, hard nipples protruding through the ultra-thin wear in front of a mirror, experiencing her first nipple orgasm. With pleasure overcoming her shame, she seduces the trainer herself, saying, "I've been holding back too." Drooling and reaching consecutive climaxes, she completely falls into a lewd female state, begging, "Teacher... please bully my nipples plenty today as well...◆"
