Due to the extreme heat, big-breasted sister reveals her home indoors in a micro swimsuit. She loses her rationality at the indifferent temptation of her lower breasts, and she gets sweaty and fucks her over and over again, two days without her parents.

The air conditioner, which has been overused for many years, has finally broken during this extremely hot season. I contacted the contractor, but I was only two days away from coming to work...I ended up spending time alone with my big-breasted sister without air conditioning, but because of the heat, I couldn't believe she would wander around the house wearing a tiny swimsuit that she had bought in bulk during the super sale (sweats) My younger brother is excited to see her sister's breasts! I tell myself that, but my ethics is also half-destructible...
