HODV-22091 · Incest NTR: Sister Couple Swap - Kaoru Natsuki (Tsubaki Kato) & Mayuri Takeuchi

My sister and I lost our parents at a young age, and although our personalities are polar opposites, we have always been together. We grew up supporting each other like twins, and even now that we have each found partners, that closeness hasn't changed. We live in a two-family home, sharing our meals and our daily lives. That was our ordinary, happy everyday life... until it wasn't. As the desires of the older sister's couple and the younger sister's couple began to intertwine, our partners became entangled before we even realized it.
