Reluctant Stepmom Needs You to Breed Her

I can't believe I'm actually doing this, but I wake you up in the middle of the night to beg you to help me. Your step-stepfather and I had one last chance to conceive and we thought we were finally pregnant with a new step-sibling for you. But, it turns out the pregnancy test went wrong. I can't bare to tell your step-stepfather and there's only one option left that will result in a biological match. Will you help me?
