[Dodaya] Me Plus Sister Times Three!+1 [Team Rabu2]

One lucky guy, three eager new step-sisters, and a house where family bonding gets very hands-on—the youngest, Akane, gets a breathless anatomy lesson from her experienced Onii-chan that ends with her twintails splayed across the sheets and her innocence thoroughly claimed. Between begging to be bathed in cum and a bathroom encounter that leaves a voice moaning devotion through the door, the sibling harem never lets the house go quiet. Then the +1 twist: a childhood friend arrives at his doorstep, chest tight with jealousy, insisting there is no way he and his new sisters are anything more than family—yet determined to find out the truth no matter what.
