[Ronrinri Ronri] I'll Always Always Love You (COMIC LO 2021-02) {Mistvern}

A naive little sister with a heart-shaped headband barges into her big brother's room, cheerfully announcing, "Hey! We're two people who really love each other, right? Mom and Dad, right?" Her affection takes a wildly inappropriate turn as she pins him to the bed, tearfully squealing about her love before eagerly dropping her polka-dot pajamas to ride him with trembling excitement. The brother finally caves to her advances, the pages brimming with creampies, breathless "Ah!" gasps, and sweet-talking like "The little girl I've looked after since her birth." By morning, she wakes him up with "Good morning, Onii-chan," cuddling close and cheerfully offering to let him pound her adorable pussy again as soon as she gets home.
