You know, I always find it fascinating how people find ways to write stories about mother/son incest where the mother is still a virgin and doesn't involve time travel.

She gave birth but she never had sex. Hymen is just what they used to use as a metric because it means nothing has ever been inside her. Same reason why some people say anal and oral doesn't count because they're retarded

Marry a smoking hot woman, then refuse to even touch her, let alone impregnate her? Definitely smells like a mere "beard" marriage to me...

@orangedew could have also used a surrogate mother.

So insemination without penetration + birth with either c-section or surrogate mother.
