Inviting Mary

"Mm… I want Yuki's baby. A child that was created between you and me." Trisha replied. Then her eyes shot wide open as an idea came to mind. "Yuki! Mary!"

"Huh? What about her?" Yuki seemed confused. 

"I am saying we can have Mary, who we know well and can not get pregnant, help with your new issue. When I can't take anymore, you can do it with her, and then when you're about to cum you can do it in me. I know Mary is different from other A.I.'s I know this. But…. I also know Mary likes you. So it would be win win in a way, would it not? If it is Mary, I do not mind if she joins, is what I am saying." Trisha liked Mary, and Mary could not go against them or try to do anything that would cause them any future issues. But Trisha really worried about her ability to keep up with Yuki's new sex drive. She loved doing it with Yuki, but there was only so much she could take.
