Get Helen to clean up the maid

You tell Helen to switch positions with the maid.

"I guess I owe you," she says to Yvette, and hops off the bed.

Soon the sight of her perky little ass sticking up in the air as she buries her face in the french maid's twat becomes irresistible, and you plunge your new erection back inside her.

"Hey! Yvette just cleaned me out!"
