[Misao.] The Worthless Big Brother and His Stubborn Little Sister (COMIC LO 2024-12) [Jefferson Translations]

Ruru Tateishi, a stubborn 12-year-old with a petite frame and soft small breasts, mercilessly nags her worthless layabout older brother Kei to get off the floor and finally clean up. Their everyday bickering over chores and diet slips into tender, insistent kissing and desperate cunnilingus as forbidden sibling tension takes over, her slender, trembling body responding with flushed eagerness to his mouth and hands. A sweaty, deeply intimate spiral follows where the defiant little sister finds herself begging him not to slam so hard while surrendering completely to their heated vaginal union.
