Take care of my younger sister who just moved to the city

After graduating from high school, Aya decided to go to Tokyo to find a job. Since she didn't have a place to stay, she temporarily lived in her brother's room. But instead of looking for a place and a job, Aya immersed herself in playing games! She also dressed quite revealingly, with her large breasts always on display in front of her brother. Frustrated by Aya's laziness, her brother decided to squeeze her big breasts, which made Aya angry and leave.

However, to his surprise, Aya agreed to let her brother squeeze her breasts as much as he wanted. From then on, her brother comfortably squeezed her breasts, but things gradually went beyond the limit...
