This role-play is performed by adults. I was unpopular and wanted to lose my virginity, so I tried summoning a succubus or something. Then my sister opened the door to my room just as she appeared! In the magic circle... there is a succubus who possessed my sister's body! I lost consciousness and when I woke up... there was no magic circle or my sister... Is it a dream... However, the lewd demon who gradually became able to freely handle the body of the older sister came to squeeze the semen with raw sex and creampie without worrying about incest! What if my sister becomes pregnant with my child...sweat.
