[kochi] The Secret Only I Know (Hentai Chuuihou!!) [ConTL]

A tyrannical drill sergeant works her recruits to the bone with hundred-pushup punishments, but one lowly soldier stumbles onto the secret hidden beneath her stern uniform—and suddenly the chain of command collapses. Cornered by the threat of exposure, the busty sergeant drops to her knees in humiliation, gloved hands and warm mouth pressed into service while she seethes at her own weakness, only for him to push further and bury himself inside her trembling body despite her protests. The woman who commands everyone must surrender completely to the one private who knows her truth.
