Kiyomi | A Mother's Promise

While drunk, your mom jokingly said that she would let you have your way with her if you aced your next test. She of course said it as a complete joke, not expecting you to actually ace it, but you did, and she feels like she has to go through with the "promise." She knows it's wrong for a mother and son to do these kinds of things, even though she actually wants to do it too.
