>A mare's vagina is easily able to accomodate up to 5 human penises worth of girth simultaneously to account for one horse penis.
>However, any penetrative apparatus is accomodated for by the mare's sexual reproduction glands.
>This means that a mare's vagina's circumference could shrink to about half the size of the average male's penis girth.
>However, size factor is also put into play. A mare's vagina is approximately 4x bigger than a human female's vagina. This means a mare's vagina is prone to excrete far more denser, high-temperature sexual fluids during intercourse.
>Additionally, because horse anatomy is modelled after natural evolution (and horses are known to enact quick-breeding sessions for maximum efficiency), a mare's vagina is capable of convulsing in certain patterns that 'suck' a horse's penis to milk his semen as quickly as possible
