The gift was actually your wife's sister's idea -- but she knew that it was the kind of gift that you would be very happy to help give to your wife and that your wife would really appreciate and enjoy.
This is based on an actual event from when we in our 50's. My wife was between boyfriends and had not been with another man in almost 2 years. During that time we had sex with each other about once or twice a week. However, when she got a new boyfriend her sexual appetite grew enormously and she had sex with him almost daily. He worked out of his home and she would often go to his house after I left for work. I remember this one time in particular that I came home from work and my wife told me she was going to his house again because she has super horny and wanted to have sex with him again. It is amazing to see the affect that a new lover had on my wife.
Women tell their hairdressers everything....
My neighbour isn't really the masculine type. He isn't the biggest pussy of a man, but definitely not the macho husband that can please his wife to the full extent. That's where I come in. Literally. The handsome, succesfull, dominant young man that can pierce your heart in a second just by looking at you. That dude never even thought of the limits his wife would be willing to go to. He never tied his wife to the bed and fucked her face. He never made her squirt. He never experienced her being absolutely submissive, looking him straight in the eye and saying the words "Yes, daddy".
Lucky for me, I did.
