[Tsukigi Kousuke)]How The Little Brother Who Turned Into A Girl Became His Big Brother's Girlfriend [ongoing chapters 1-20]

A younger brother now living as a soft, flustered ponytail sister greets his stunned big brother at home with clingy affection and a jealous pout. Possessive and desperate to keep him all to herself, she straddles his lap with flushed cheeks and smooth thighs, pouting that a girlfriend in Tokyo would mean he cannot play with her anymore while her newfound popularity brings love letters from both genders. What begins as a bewildering sibling reunion quickly teases a sweet, intimate slide from brotherly teasing to girlfriend devotion as she vies to become his one and only.
