I [M] 32 Spanked and Fucked my nanny [F] 25 after I found out my wife cheated on me. [MF]

I’m drunk as I write this so bear with me. I don’t know who to talk to and I still feel guilty af.

Quick backstory:
My wife (33) and I have been married since our early twenties and things were going great until I found out she was cheating on me for quite a while with a male friend of hers. We are still together as I write this story and the nanny still works for us and my wife has no idea what has happened between us. Our nanny has been living with us for about three years and is married but separated from her husband (they’re Catholic so she won’t get a divorce). When our nanny arrived at our doorstep on the very first day we were very formal with each other and continued to be so for quite some time. Most of the communication happend between my wife and her while I was in the background. Our nanny is Filipino and very petite. She’s young and pretty but doesn’t realise how pretty she is. She barely weighs 50 kilos, has B cups, and a tight little ass. Over time the two of us became very close in a platonic way and I would give her advice on how to deal with her personal issues and when she was down I would give her a great big hug and tell her everything would be OK. We had our inside jokes, and high fived all the time and went out together to get coffee sometimes as well. My wife knew about it and was okay with it because she was a mainly unempathetic person and wasn’t a great listener but wanted to know our nanny was doing ok so it wouldn’t affect her work.Things used to be great in our household and everyone got along and she was great with our kids. All was good.
