I plan to go to Tokyo to see the concert, but the accommodation is full and I will be taken care of at my sister's couple's home. Tsubasa, who saw the fierce activity of her sister and her husband seriously on the night of the first day of accommodation, has a sexless body that aches and indulges in masturbation. Without knowing that such a figure was being looked into by my brother-in-law. And the next day, my brother-in-law approaches Tsubasa as soon as his wife goes out as a part. Even if you know that it is a good act, the sexless body will drown before the unequaled energy.
