Haruka is a pure school girl who had never pleasured a man before. Tempted with the suggestion "Why don't you try teasing his nipples?", she embarks on an experience that transforms into her own pleasure. Drooling as she licks his nipples, gently biting them, she gradually understands male sensation, connecting it to her own arousal. She masters two triple-teasing techniques: first, cock sucking combined with dual nipple play, and second, grinding plus dual nipple stimulation. After removing her soaked panties, she moves from grinding to direct bareback penetration. Even while being pounded hard by a huge cock, she confidently adds nipple play during cowgirl position, revealing her aggressive side. Unsatisfied after just two rounds, she ultimately enjoys her favorite sex to the fullest with three consecutive creampie orgasms.
