I found a copy of "Dr Brown's Book of Best Bonking" in the reference library.
It read "The best bonking is on the D7 planet. Their people are similar in appearance to us earthlings, except they have no anus.
The women all have breasts and vaginas. Their bodies are covered in hair (similar to earthlings pubic hair) except around their breasts and vaginas. Unlike earthlings, they have no clitoris or other erotic zones.
The men all have flaccid pricks of at least 7 inches. Most are endowed with 10 inches, and many with 14 inches. The largest recorded is 18 inches. All have an erect girth of 4 inches.
The average D7 woman has a C cup sized breast, but most have a B cup.
Social status is decided by the size of a flaccid penis or the breasts. The higher the status the more sex a person is allowed. The Emperor has the first chose of any woman and few escape his monster penis.
The low status (7 inch) man might only have sex with 8 women in his lifetime. Whereas a high status (D cup) woman may take 27 lovers in a year. If she sees a lower status man who she likes they retire to a public double bed. A passing member of the public will sheath the man. People then watch as the man gives the woman the types of sex she enjoys.
A D7 man deflowering a D7 woman attracts much attention from a crowd of up to 100.
By law sex can take place only in public.
Their only sensitive erotic areas are the penis and the vagina. Men can sustain their lovemaking for up to 4 hours, but few women choose to be bonked for that long. Mostly sex lasts for about an hour.
Their sex positions are even more varied than earthlings. They seem to believe that variety is the spice of life.
As a population control measure sex has to be with a sheath (condom) unless the Emperor decrees otherwise. Human sperm has millions of tadpole like creatures. Their sperm has 5 large tadpoles. The woman produces 5 eggs. Unprotected sex is 100% effective. So a woman will automatically bear 5 children if a condom is not used."
Dr Brown concluded with this statement "For females with large breasts, and a larger libido, D7 is the perfect planet. The men on earth are boring in comparison with those on D7."
ESCAPE
My 2 older sisters (Rose and Heather) and I decided that we needed to get to planet D7. My sisters have D sized breasts but mine are double D sized. We would all be high status. We all and wanted an unlimited supply of large cocks. We all resisted the urge for sex with mere human men.
What woman wouldn't want a crowd of 100 people watching a monster cock take her virginity? Especially if we could take any man we desired and have as many cocks inside us as we liked.
