You watch for a while

Claire reaches down with her hand and rubs Tracy's slippery cunt lips roughly with the palm of her hand. You watch as the nanny goes weak at the knees and leans back against the bathroom wall for support.

Your wife works her hand all along the slit letting her fingers slip inside as the lips swell and open up. Tracy pulls your wife's face close to hers and french kisses her hungrily. She begins to moan as what your wife is doing has the desired effect.

It's as though you aren't there.

Claire now has two of her fingers in the nanny's cunt, with her thumb on her clit rubbling like mad. Tracy's eyes are closed and she's breathing heavily. Her nipples are erect. You can tell she won't last long.

Claire looks over her shoulder at you and winks.
