[Reducing Mosaic]KSBJ-030 Big brother's wife Karen Minegishi

I am a part-time worker and currently live with my brother and his wife. Karen, my brother's wife, is slender and amazingly beautiful. One day, when I came home from my part-time job earlier than planned, I saw her sister-in-law putting her hand on her crotch in the living room. She was upset by the sudden incident and rushed into her room to escape. That night, when I was in the bathtub, my girlfriend's sister-in-law came into the bathroom completely naked.
