How Ponies Reproduce

Mares have their genitals in their brain, and stallions constantly secrete semen with their saliva. When a stallion licks a mare's ear, the mare gets pregnant.

The foals are born rapidly and the mare suffers brain damage.

Twins are the result of licking both ears simultaneously.

Alicorns are the result of a freak genetic mutation, so fuck that shit.

Changelings are born like normal insects rather than in the previously mentioned pony reproduction. Therefore, they are the master race and ponies suck nonexistent cock.
