I found my wife masturbating with the vibrator I gave her

When my wife turned 50, I gave her the latest model of a very popular vibrator on the market, capable of satisfying any dissatisfied mature woman like her. I thought it had been an absurd gift and that it was of no use to her, but the surprise was mine when I got home one day and found her on the couch with her legs apart and masturbating with the vibrator I had bought for her.
