部屋結界×NTR ～この家族は全てワシの思うがままじゃ イヒ！～SDDE-644

This time, the room barrier is NTR! With the power of an evil spirit, a gross old man makes your beloved family members get creampied one after another! Your proud beautiful wife gets violated right in front of you, and then her older sister and beloved daughter fall victim to his poison. After creampie-ing all of them and brainwashing them completely, the gross old man declares polygamy and turns the three into his submissive wives, making them serve him in a clothes-free harem—while you can only watch helplessly.
