[ Anime Sex ] Body Transfer 1

During the summer vacation of the high school, an archaeological club member received a curious vessel that had been used in a religious ceremony. When the light from the vessel shone on us, the other members of the club and I were blinded by our own guilt. When I regained consciousness, my conscience had been placed into the body of Kurahashi Yoshimi, whom I saw as my older sister and admired. Her girl's body was very soft, smelt wonderful, and was quite responsive to sexual pleasure. It seemed unjust that the lady was such a stark contrast to the male... The other members who were exposed to the light from the vessel had their thoughts and bodies switched, and they were transported into the hidden realm of sexual desire as well. The weird occurrences occurred again and over again. Were they going to be able to return to their home world?
