I tried to make fun of my older sister who claims to be a succubus, but when I offered her my dick, she was forced to give me a blow job, licking and sucking and swallowing my cum deep in her throat. No Sato?
My parents went on a trip, so I got 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. As a tease, I held out my erect penis to her, and she said, ``A man's energy is energy! I'm going to suck it all out!'' and she forcefully licked it. During the three days when her parents were away, I had her older sister, who pretended to be a succubus, suck me and swallow my cum over and over again.
