I'm a teacher and I'm dating my student Momoto. It's a secret relationship that we can't tell anyone about, but she somehow resembles Kana, an ex-girlfriend I used to date who I broke up with due to differing views on marriage... Wait, what?! Could they possibly be sisters!? Is this even possible? Or maybe it's fate...? We're constantly jealous of each other and fight over my dick! Even during sex, we're in a beautiful sister sandwich and I'm running around like crazy! Their pussies are identical too; before I knew it, I completed a lucky sister donburi harem! Every time, I finish with a thick load inside, so maybe I'll just marry the one who gets pregnant first～!
