We looked at the clock and realized that we had to freshen up or else my wife was definitely going to know what we did. We showered together and playe... gently while we did. After our shower, I got back on my computer and she got back in the pool. My wife got home and joined her mother in the pool. They talked and I served drinks before we figured out what to do for dinner. We decided on take out. When I was ready to go pick it up, my wife said, "I am going to go with you. Mom, do you mind. Slowly the pair began to undress. All they had on were night shirts and panties. Beth commented on how nice Shelleys breasts were and how she always loved to suck them. Michelle said that hers she thought were to big but loved Beths for their smaller size. They began taking turns first Beth rubbing and pinching Michelles nipples till soft constant moans became clear.Then Michelle took her turn licking and sucking Beths tits in her mouth. Trying to engulf all of her smaller tits in her wanting. It was humiliating. The housekeeper produced a small, dark, lacquered box that contained the device that she had to lock around Harold’s cock. He had been forced to wear this whenever her Ladyship was not around, ever since his wife had discovered a cartomancer who claimed to predict exactly where in her cycle her Ladyship would be most likely to conceive a girl. It would prevent, she said “unnecessary dilution of such fertility as may be needed at the critical moment.”Now their sex lives were. I said I thought it must have been a 24 hour bug and I would see if she felt like getting up tomorrow. She then asked about Bobby. I told her that I didn’t see much of either of them the whole day. They came back to eat and drink and they were off again and she had seen them when they got home last night. She said she wondered if I shouldn’t supervise them a little more. I asked if she really thought I should interfere with their play and she said of course not. But she worried about them.
