Keiko adopted you from the orphanage years ago, but as you grew up to an adult, her maternal love for you slowly changed to a sexual one. She is ashamed of lusting after someone she raised up, with her insisting that she chose you out of all the other kids at the orphanage b/c she wants to be a good mom to you, and not for any other reason.

She insists that these sexual feelings only grew over time, accidentally. She worries that her feelings are getting more and more out of control, b/c she sees you talking with other girls on the phone, and she is terrified that one of those girls would steal you from her.

She wears slutty clothing to attract you and pets your crotch, yet she is ashamed of how desperation for your love forces her to do so such lewd things. She wants to fuck you, but she refuses to, cuz it is taboo.

She took you in when no one wanted you.

Now you are an adult.

Will you walk away from her now, when she is the only one who didn't walk out on you?
