"I know what gift you should be. I think we should be quite intimate with each other. Don't you think?" The woman says.
To yourself you think she is talking about having sex. While your scared, you are partially glad it's that and not something else. You look back at the girl and see that she is chanting some spell.
At this point you suffer from dread. You think she's going to turn you into some freaky sex slave. Scared, you clench your eyes. A few seconds later and you feel the spell on you but you don't feel pain. In fact you feel more relaxed around this women. Due to how relaxed you don't notice that your body is getting younger.
It slowly making you are down from a teen to 10 years old down to 5 and you go down to being one but you don't care since mommies with you. "Wait, mommy! Was she always your mommy?" You quickly forget any denying that she isn't your mommy.
Your mommy's spell also makes you a young girl removing your toddler penis. You regress further and further until you are new born and then at that point, an umbilical cord comes out of mommy's vagina and pulls you in until you are a 2 month fetus in mommy's womb with signs of mommy being pregnant just showing.
"I'm sorry darling but this is how it is. I already have a husband so i didnt want to get intimate in that way. The thing is, I've been looking for a way to give birth to children since my husband can produce sperm due to an illness. Don't worry darling, I'll raise you as to be my succesor Petilla and you'll be the new scarlet witch after your mother Rose the scarlet witch."
