u can tell a a horny story online was written by a cishet dude if it describes a major female character like
She had waist-length flame red hair and luscious D cup breasts. She was 5'7" tall and had hip-waist-bust measurements of 40"-25"-40".
Once again tempted to see if I can trick cishet men into cranking it to drider smut by pointing out that abdomen/thorax divide would technically create an incredibly small waist.
