I am not sure if it is animated. It is a straightforward visual novel like flipping through pages.
A vaguely remember the details. A guy meets a genie or succubus in his house and gives him one wish. He wished for the woman on a magazine but instead he is turned into a woman that looks like the one on the magazine. The guy, now a woman, meets with friends? in an empty lot. They fight for a bit but the guy/woman gets overpowered and gets gangbanged there. They take her to a warehouse looking place and continue to gangbang her. The succubus shows up again and drains the life out of the guys. Succubus take the gender bent woman back to the house and they have sex.
