Of Course She's My Daughter

My husband has asthenospermia, so we decide to try IVF.

Before the embryos are combined, I catch my husband switching my ovum out for his true love's. I don't say anything and switch them back. At the same time, I switch my husband's sample out for my ex-boyfriend's.

25 years later, my husband's true love comes knocking. She holds my daughter's hands and weeps while saying, "I'm your mother, my darling!"
