[Ahemaru] Shinobu-san no Goumon Shiken (Kimetsu no Yaiba) [WataTL]

Shinobu Kochou lets herself be strapped to a chair, smugly daring her captors to pry a Hashira's secret out of her by any means they like. Their 'torture method solely designed for females' turns her huge breasts into the battlefield—drugs swell them bigger and more sensitive, clamped nipples and relentless battering force milk spraying from her body until every blow wrings another orgasm out of her. She swore she'd never yield, but as the lactation-cumming addiction takes hold, the line between torment and bliss starts to blur.
