When the older brother who was present gets drunk, he is persuaded by the man he meets for the first time and falls. When I feel that my hips are twisting while saying that I'm going to get caught ... I'm stabbed by a cock and ascended many times. I blindfolded and changed to my brother when I reached it again.
