Okumura has always been interested in Yuna, the mother of his friend Kota. One day, Okumura, who decided to stay at Kota's house, put her Yuna to sleep with her medicine, stripped her naked and took a picture of her with her mobile phone. Later, Okumura sneaks into Yuna's room and finds her undergarments. After that, Yuna's bra was taken away, and she was played with beautiful breasts that swayed with no bra on a daily basis.
