[Fumihiko] Sis Bro (COMIC Megastore 2012-08) [Life4Kaoru]

Teased one too many times by his apron-clad little sister Anzu, a flustered older brother finds his protests crumbling the moment she bares her petite body and wraps her small fingers around his cock, purring that siblings have nothing to be shy about. But once that line is crossed his restraint shatters entirely—he bends her over and buries himself to the hilt in her virgin pussy, the x-ray view tracing every thrust as she wails onii-chan with rolling eyes and a drooling, broken smile. A sibling one-shot where the smug little seducer discovers exactly what she unleashed.
