Teasing My Sister Who Claims to Be a Succubus with a Second-Year Syndrome and Long Tongue, I Offered My Cock Only to Be Overwhelmed by Her Bragging Blowjob, Intense Sucking, and Deep Throat Cum Swallowing. Nonoka Sato
While my parents were away on a trip, I casually peeked into my sister's room and saw her standing in front of the mirror shouting, "O evil spirits, swear your loyalty to me... Shadow Mortis!" There she was, dressed as a succubus, muttering mysterious words. When I called out normally, she snapped, "H-How rude of you! I've taken over your sister's body! I am the succubus princess, Eira!"—my sister completely lost in her delusional fantasy. Half-joking, I offered her my cock, and she boldly declared, "Male energy is my power source! I'll suck every drop from you!" before starting to lick it. For the three days my parents were gone, I made my sister—dressed as a succubus—give me blowjob after blowjob, swallowing every load, experiencing something utterly bizarre.
