Takeru proudly introduces his sweet girlfriend Megumi to his teasing older sister Kyouko, a busty futanari whose massive, throbbing cock instantly leaves the innocent schoolgirl flustered and fascinated. What begins as a shy greeting quickly unravels as Megumi's soft, heaving big breasts and trembling curiosity give way to desperate, love-struck submission to Kyouko's overwhelming size and playful dominance. Torn between loyalty to her boyfriend and her new aching devotion to his sister, Megumi begs for Kyouko by name, slipping deeper into a cheating netorare spiral where every kiss and thrust makes being stolen away feel irresistible.
