I don't know if that can be called fetish. Because, in my opinion, it goes way beyond that. Maybe it can be explained as an extended lifestyle? It helped me cope with my jealousy when we started. I had already written a little about it and later I was able to classify everything better. My mother used to punish me when I got naughty or when I annoyed my sister. But also with poor school grades. I mean diapers. I was a wild child and often overstepped the curve. Nothing could stop me - house arrest - I just laughed about that or slaps on the buttocks - then I laughed even more. But when my mother (and her sister, i.e. my aunt) started diaper discipline, I didn't think that was really funny. The Discipline diaper could last a day, but sometimes three or six weeks. Back then, I was seven or eight years old and then I had to get a baby diaper like Pampers, Luvs, Huggies or Fixies and wear them to school. I still remember walking home from school with a wet windward wind. But somehow I learned not to break the rules anymore. Well later I wore it for fun. We started cuckolding. She met someone from the internet, maybe from Facebook. We invited him over to our house and she liked him straight away. I took care of the food and the two of them drank some sparkling wine to loosen up. It didn't take long and the first kiss was there and I served the starter - gratinated sheep's cheese with a little paprika. With tsasiki and lightly toasted bread. I saw how he had one hand on my wife's bosom and the other slowly disappeared under her skirt. I was boiling inside. Later, when we had eaten and I was briefly in the kitchen - when I came back they were gone - in the bedroom. My mind was racing and I imagined how they would do it. I put on my jacket, my cap and went out for a walk. I was jealous to no end. A few days later (my mother knew about the Diaper Discipline from my mother) my wife bought a few packages of diapers. So again Diaper Discipline - which was then expanded into, say, Baby Discipline and now determines my life 24/7.
