Waka Takatsuki's son, Taichi, spends his days cunningly eyeing his beautiful mother. One day, claiming it will help with weight loss, he approaches her with a vibrator in hand. As he passionately kneads her G-cup breasts, he intensely stimulates her through her sheer panties. Overwhelmed by his fervent foreplay, Waka reaches orgasm, her body glistening with sweat from her son's vigorous touch. Soon, she is thrust into fierce intercourse, receiving a thick creampie as she floods the bed with cum and sweat, climaxing in ultimate satisfaction. This title presents an intense, sweat-drenched sex scene in two parts, captured in a documentary-style format.
