Use the Shower Against Her While You Fuck Her From Behind

Yes, feel yourself slip away. Submit to the pleasure.

You grab the shower, and pull her close to you, wrapping your arm around her neck and holding her in place. You wrap the shower pipe around her with your free hand. Then, you start to fuck her hard from behind while you push the shower head against her pussy, using the high water pressure to push her closer and closer to cumming.
