[Sena Youtarou] Perverted Onei-chan Ch. 1-6

An older sister's lewd advances toward her flustered little brother spiral into chaos when a smartphone captures every compromising moment. As demonic curses trigger and a tan, ponytailed classmate named Mahiro gets caught in the mess, the perverted onee-chan finds herself being the one thoroughly conquered. Sena Youtarou delivers a wildly comedic saga of defloration, incestuous tension, and ahegao-filled climaxes across six chapters of escalating mischief.
