MIDA-238 Secretly Awakening the Sensitive Side of My Fair-Skinned, Busty Younger Stepsister and Living Together in a Secret Relationship, All While Keeping It Hidden from My Wife — Yuno Sakura

Yuno, my wife’s much younger sister, came up to the city for summer classes and ended up staying at our home for two weeks. She has a gentle personality and, without realizing it, can come across as unintentionally alluring because she is so unconcerned about how men might look at her. Her innocent face and fair skin caught my attention, and I decided to play a little prank on her without letting my wife find out… I planned to make her react in a way that wouldn’t get back to my wife, Yuno’s older sister. After that, her sensitivity increased, and our relationship became one of repeated secret encounters with my younger sister-in-law.
