[China] Imouto wa Doujin Shoujo Cosplay Kei Ch.1-11 [biribiri]

A doujin-obsessed little sister makes her older brother her favorite model and muse, pulling him into the manga research club's cozy after-school world of cosplay, art practice and teasing dares. As the sole male surrounded by a devoted harem of petite classmates in schoolgirl uniforms, stockings, maid and bunny outfits, every costume change becomes an excuse for heated, close-contact play with soft small breasts and trembling thighs. Flustered whispers in the clubroom soon give way to tender kisses, aching first times and warm, creampie-filled afterglows that keep the whole circle coming back for more.
