Living as my master's beloved pet, I spent each day being disciplined and pampered. Then one day, my master said to me, "It's not like I'm actually your father or anything, but we're like family... It feels awkward and embarrassing, like having sex with my dad or older brother." Hearing those words, I gathered my courage and confessed my true feelings. "Then let me erase the 'Nana Mizuse' in you." From that moment, my master began training me in various outfits. Wearing these perverted costumes intensely triggered my masochistic desires, unleashing an uncontrollable lustful excitement. When I stood before my master wearing white dog ears and an anal tail plug, I felt the same nervous tingling sensation as when I first showed my new school uniform to my father upon entering middle school, mixed with a deep craving for attention. I longed to be touched, to serve him. The instant I turned my backside toward him, my mind filled with the heat of a bitch in heat, overwhelmed by an unbearable desire to be taken. When I played the role of a succubus, teasing and dominating him, an intense itch stirred deep within my rear, driving me to taste my master's cock according to my primal urges, begging him to take me anally.
