In a not-so-distant past, husbands could not rape their own wife legally speaking. They could do so physically and there was nothing she could do. Some husbands from days gone by liked to bring their best friends so they could all gang-rape the wife. There were no doubt some forms of secret “wife rape clubs” where they played cards to decide who was first, all nice and legal of course. The wife’s consent or lack of were irrelevant. This was one form of socially accepted abuse.
Female soldiers are about 90% likely to get raped when they are captured. Sexual violence against women from men of the same side is more or less normalized, so when they fall in enemy hands, it’s even worse. This is a constant fantasy of mine. Military nurses pay the price too when the enemy makes a breakthrough and captures an entire division, including its field hospital.
As someone once wrote in a comment for one of my stories, the Geneva Convention is just as easily torn away as the female officer’s panties. To imagine a French officer, daughter of a prefect or a Mayor, getting filled up repeatedly by soldiers screaming “Allahu akbar!” somewhere in Sudan… That’s a turn-on! Fantasy only, of course. If you declare jihad against the decaying West, raping their women is part of the course.
