Sister gets naked in front of her brother in Heavenly Delusion Season 1, Episode 1 (2023)

What a great start to a mainstream anime! We see the protagonist first in the toilet, where her companion, who calls her Sis, enters, then we see her getting naked for a bath, and let me just say her body is so hot. She also tries to kiss the mirror, because that's what you do when there's a man with you, right? LOL
