Hiroki started working part-time at a restaurant run by his friend's parents, but as he worked with his mother, Natsuko, he came to realize that she was the opposite sex. Then one night, after work, I missed the last train and was asked to stay at Natsuko's house for the night. Unlike her workplace, Hiroki desperately hid her excitement as she was wearing no bra that generously exposed her plump body. However, Natsuko, who got drunk and exploded with sexual desire, could not stand it and led his hand to his chest.
