[Chiguchi Miri] Dick Hypnosis Incident (Ikenai Koto Kamo...) [Tamamo]

A mischievous younger "imouto" in a plaid top gets her curious hands on a stray hypnosis spell card and quickly turns it on her older "Riku-kun," bending him to her whims with playful commands about her panties and pulling down his pants. The bespectacled boy sweats and flushes as she straddles him in her underwear, leaving slick trails across his skin and pushing inside while teasing him about being "small," until he ends up finishing on her bottom with a drawn-out, trembling climax.
