Demonic impregnation ritual

You have been chosen as a vessel for the children of Satan, the Lord of Hell. You are led to a black altar bearing a large pentagram. Thousands of demonic souls, in the form of purple spheres, fly around the room, circling above the pentagram. At the end of the corridor, a giant Satan sits on a throne and looks at you with a mocking smile. As soon as the ritual begins, demonic souls will start to enter your womb or belly through the skin (if vessel is male because male don't have womb) without damaging your body. Each time a demonic soul enters, your belly will grow larger. You will become pregnant and feel Satan's children moving inside you. During your pregnancy, you will be extremely hungry, so Satan will provide you with a refrigerator full of endless food and drink. Your pregnancy will last nine months. Your belly will grow larger as Satan's children grow in your womb or in belly if vessel is male because male don't have womb, until they reach adulthood. Your insatiable appetite will cause your breasts and buttocks to grow larger as you eat so much food, your buttocks will be get fatter too. After completing the impregnation ritual, Satan will teleport you to your home, where you can keep yourself busy while you are pregnant. As many demonic souls will enter me as Satan desires. They will enter one after another, in succession. The ritual has made your belly able to stretch without limits. The pentagram will glow purple during the ritual.

After nine months, Satan's children will come out through the uterus or through the penis via the urethra (if the vessel is a man), stretching it in the process by coming out Satan's childrens. After giving birth, the uterus or penis (if the vessel is a man) will be deformed forever by being stretched.
