DVAJ-033 Older sister Tsukasa Aoi wandering around in her underwear

Tsukasa's hobby is collecting underwear. - I wore the collection and indulged in daydreams in front of the mirror. - However, all of her favorite sexy underwear were stolen. - Suspicious of his younger brother, Tsukasa sneaks a peek into his brother's room from the balcony. - Then, the younger brother was masturbating using Tsukasa's underwear. - The next day, I searched for my brother's room, but couldn't find him. - I had no choice but to provoke her in my underwear and make her open her mouth. - The younger brother was reluctant to confess, but he did so after being sexually assaulted. - From that day on, he began to feel pleasure in dominating his younger brother and torturing him erotically.
