After a long time away, I returned home to find my little sister, Kanon, transformed into an unbelievably cute schoolgirl. With our parents out, it was just the two of us at home. My heart pounded as I caught glimpses of her—napping in the living room with her panties fully exposed, or wandering around wrapped only in a small bath towel. Before I knew it, she sneaked into my room while I was asleep, gently touching and stroking my rock-hard cock as I masturbated, pushing me right to the edge. Can I possibly resist my sister Kanon's intense, relentless seduction?
