For my birthday my wife booked us a day at a high-end spa. Something I didn't want to do but she would enjoy and it was way overpriced. We hadn't been talking anyway and the drive there was so awful.

We went to sauna and the pool and then had a booking for a mud clay treatment. A woman greets you at the door to a private room. She explains that we each stand in a cubicle to have our bodies sprayed for 3 minutes with a special water. Then we are to apply the mud to ourselves with help from each other for our backs. The attendant says there's no lock on the door but she will be standing at it to stop anyone entering. Paper underwear was supplied to protect our modesty. We have a maximum of 15 minutes in the room.

When we began applying the mud to each other my wife pulled my swimming shorts off and started to suck me off. I tried to stop her because we were getting along so badly (I can't remember why). Then she turned around begged me to fuck her.

When our time was up the door lady asked if we enjoyed it. I've no idea if everyone does it.
