My parents went on a trip, so I had some free time, and when I sneaked a peek into my sister's room, I saw my sister dressed as a succubus in front of the mirror, saying, ``Evil spirits, pledge your allegiance to me...!Shadow Mortis!'' was uttering mysterious words. When I called out to her normally, she said, ``Hey, you're being rude! I took over your sister! I'm the, erm, succubus princess Ayla!'' had completely become a succubus. When I offered him my erect penis in a teasing manner, he forcefully licked it, saying, ``A man's energy is energy! I'll suck it all out!'' During the three days my parents were away, I had my older sister, who pretended to be a succubus, suck me and swallow my cum over and over again.
