[Countack (Kojiki Ohji)] Chifuyu-chan's Sin & Melting Lips

Little Chifuyu has her adult boyfriend completely wrapped around her finger, and on a packed evening train she proves it by branding him her personal 'chikan molester' while grinding her bare, pantyless ass against his suit. What starts as mischievous molestation play escalates into her small hands stroking his aching cock until the composed glasses-wearing adult is trembling at his limit—no penetration, just agonizing friction and the giggling promise that they can fuck later if he's good. This sequel chapter flips the power dynamic entirely, letting the tiny temptress call every shot while her flustered lover barely survives the ride home.
