When a woman of breeding age finds out that she will be serving an extended prison sentence which will render her infertile by her release date, yet she still wishes to reproduce, she will endeavor to have a door baby.
This is done by coercing a male donor to ejaculate into a small, tubular receptacle, usually a toothpaste tube. The tube is then smuggled into the cell via a food tray. The most common way to do this is by placing it within a hamburger bun at feed time.
The prospective mother will then insert the tube into her vagina and squeeze. Thus, with any luck, the miracle of life will occur.

A child conceived from the mother engaging in anal sex and allowing for the semen to drip from her anus into her vagina.

In order to achieve impregnation the male must first ejaculate inside of the females rectum. The female will bow her legs tilting her body forward. The female will then take her hand and gently spread a cheek allowing for the anus to expand and create a conduit for the semen to trickle down towards her pubic region. She will use her free hand to catch and vigorously rub the anal semen into her vagina.
Whats wrong dude?

Yeah, I guess mom was really into the anal cream pies back in the day
