[Karasuma Pink Higashiiru (Karasuma Pink)] Erodōninshi de manabu jitsuyō eigo vol.1 (Kingdom Hearts)

A doujinshi that blends English language lessons with explicit yaoi scenes starring a spiky‑haired Riku and his companion Sora. Panels depict heated, close‑up encounters—anal, blowjob, and other intimate acts—while the characters trade instructional lines like “concentrate on your cock” and “you must make him yours,” creating a charged mix of education and desire. The story is urgent, provocative, and designed to titillate while teaching, making it a bold, adult‑oriented tutorial for fans of shotacon and gay romance.
