Submitting Myself for Milking

With Jillian around, things are getting a little complicated. For one, she's my opponent now. She thinks I'm her friend, but now that I'm living with Chris, I find myself only wanting to please him, especially now that I'm pregnant. Each day being milked is a dream come true. I see her scheming behind my back to become his favorite pet, and my heart boils because of that. I have to come up with a plan, but how? Maybe submitting myself to whatever game he wants to play with me will do the trick. Note: characters are consenting, unrelated adults.
