Her husband went to work far away, because he was too emotionally deprived and often had sudden flare-ups, so the lewd young wife Iori masturbated many times to satisfy her physiological needs. And it was a fateful day, when she was masturbating, suddenly her brother knocked on the door outside, because she was in too much of a hurry and panicked, she couldn't take precautions, so she had to tuck her sexy underwear right under the foot of the table. Unfortunately, it was a very easy position to catch his eye—who was a very careful observer of his surroundings. He was also a very bastard, taking advantage of that panty, he had asked her to accept to make herself happy by having sex or she would tell her husband the depraved things she had done. Because she was so scared and threatened, she had no choice but to grit her teeth and endure even though the bastard brother was raging on her body.
