Why not

Abby squirms but she still cant move the only thing she can do is sigh out a yes to signal the bet. Brenda immediatly begins working the dildo in and out of her pussy thrusting at a good pace. Abby realizes she is getting closer to orgasm when Brenda stops. Ordering her into a new pose she is bent over her desk her pussy and ass lewdly displayed behind her. The dildo now pumping into her from behind she feels she is going to make it when a foreign finger enters her rear. The double penetration causes her to moan out and her pussy squirts all over the dildo and leaks down onto the floor.

"Meet me in my office after work." Brenda whispers. Abby can suddenly move again as she looks for her dress. She barely manages to fit it back on realizing Brenda stole her bra and panties. As she is still coming down from her orgasm she has to get back to work abd awaits her punishment from Brenda.
