[Reducing Mosaic]LULU-272 I tried to tease the long-tongued sister who insists she's a succubus, offering my dick. She then aggressively gave me a milking blowjob, sucking and swallowing repeatedly. Sato no Ka

Since my parents went on a trip, I had nothing to do and sneaked into my sister's room. There she was in front of the mirror dressed as a succubus, chanting, "Evil spirits, swear your loyalty to me! Shadow Mortis!" If I called out to her normally, she'd say, "Thou art impudent! Thou hast taken over thy sister! I am the succubus princess, Eila!" My sister was fully immersed in her delusions. Half-jokingly, I presented my erect penis, and she said, "The energy of men is vital! I shall absorb it all!" Then she defiantly licked my penis. Over the three days my parents were away, I had my sister, who was role-playing as a succubus, give me blowjobs and swallow my semen multiple times.
