My mother's best friend Suzu takes care of dinner in place of my parents who are going on a trip. Kenji wasn't expecting his mother's best friend to be an old woman, but what appeared in front of him were breasts that looked like they were about to spill out at any moment. Kenji was captivated by her overwhelming breasts, which were visible even through her clothes. Suzu tries to pretend to be sick to keep Suzu from getting ready to go home, but he sees through her cute lie and plays a naughty prank on her.
