Ruby lifted her head, her hands still working his balls as she watched him, listening to the challenge. A slight smirk came to her lips as she listened. Heather looked at him as she listened. A gasp escaped her when she felt herself being spread. Ruby watched Heather and thought for a moment before smirking a little, "I think she'll do alright. I'll do just as well or better," she answered with a grin. Heather looked back at Ruby with narrowed eyes, "You won't," she stated. They were friends, they were loves, but it was clear they enjoyed challenging one another and trying to beat one another.
