Had an affair with son's favourite teacher which went for more than a year

I am a corporate slave too but there was a time in my life where I took a sabbatical from work and wanted to take a mental break during that time my son was in school and he had a teacher who was interested in providing home tuitions to him and we agreed with it. The guy is in his 30s maybe mid 30s and surprisingly captivating persona, straight face, always sharing facts and everything. He used to come during our tea time and sometimes we used to first drink tea together and then he would start his classes. Eventually he started become caring for me Idk how and in a very rude manner, like he used to scold my son for asking silly things from me that he can take care of and I kinda liked it as he was straightening it out and gradually he started being very open about his feelings for me. He liked how I dressed, how I looked, my cooking, everything and I liked that attention coming from him. Over the time I started to enjoy his gaze and would sit with them during the classes wearing tight clothings and he would enjoy it. He started coming home early while my son would be sleeping post school. We would flirt together and make out in the kitchen and I wanted to keep this going for long and keep it secretive so I took babysteps, it was close to 2-3 weeks for us just making out and not moving forward, we would rub each other but thats all. Now we wanted more, next day when he came, I locked my son's room from outside and make this guy sat on the couch and i blew him so beautifully he would remember that for lifetime, he came after few minutes and I helped him clean and he fucked me that day, it was a quickie but that initiated our sex which would go on for like a 6-7 months then we had to stop doing it. We still talk and meet once a year so.
