Two Can Play That Game.

I'm a newly single mom of 2 in their late teens. Up until recently , my life was perfect. My husband was great. My daughter (18) was doing well in life, and my son (19) was finally making a name for himself editing for some successful YouTubers.
I have run my own mobile hairdressing studio business for 8 years and my Husband is in finance, with his own successful company.
I still don't know how this all started, but it did and I ended it. I have had nobody to talk to about this. My friends have no idea of the truth. It's likely because of our successes that we will all be silent forever about this.
Here's a quick summary of the night that ended my fantasy happy life. I feel now, that it was all a lie. I ran late for an appointment late one afternoon, and my client cancelled on me. This is super rare, but it was a 2 hour drive to get there, all for nothing. Fortunately with almost zero traffic on the trip home, I was home an hour later. My daughter had lined up the client, so she knew I was meant to be there for at least a couple of hours at work, plus travelling time. I drive a quiet car, so nobody heard me enter the house. They also weren't expecting me home for at least another hour or more. I walked in and immediately heard the undeniable sounds of sex coming from my room, charging towards it in a rage, my adrenalin raced though my body preparing me to take on whoever my husband was cheating with. I can actually fight well, this woman had dared enter my world an I was mentally preparing to destroy her, with all my fury. I was fuming as I stormed into the room. I flung the door open so fast, almost broke it.
Then absolute shock, mixed with horror. It was far worse than I was imagining. Far, far worse. Yes, I was right about assuming my husband was having sex with another woman, but it was who she was that stopped me in my tracks. It was my daughter! They were both fully naked and she was riding her father! Instantly I as loud as I could, HARRY! GET HERE NOW!! Harry is my son. I wanted to see his face when he came in and saw what I was seeing. MOM, NO! Teagen pleaded as she grabbed the covers to hide her breasts from her fast approaching brother. The reality that Harry wasn't aware was a relief as he ran into the room like I was under attack. He almost skidded to a halt, saying Oh my God, Teagen! Dad? What the fuck? He exclaimed in total disbelief. I had a plan. it wasn't a thought out plan, nor was it wise in any possible way, but it was a plan. I immediately began to put my plan into action. I popped off my top,dropping to my knees in front of my son who stood there, now in even more shock. I reached into his pants with my hands, and as I pulled out his dick, I said, Two can play at this game. I found out later my son did stop me out of pure fear, because he could sense my anger. I sucked Harry hard Teagen was still on her father's lap saying Mom stop! She knew why I was doing this. I was taking back some power in my house. It wasn't a great decision. I wished I had listened to Teagen when she said stop, because I was only giving head at that point. Within a few minutes I had my poor son hard and pushed him on the bed beside his father. Then I dropped my pants including underwear and mounted my son. All was silent as I began riding him, so I said if Teagen thinks she can fuck her dad, then I will fuck her brother! I actually wished she had a boyfriend and it was him, but anyway my options were limited at the time and besides bashing both my daughter and her father senselessly, I chose this. My son was pretending it wasn't happening. Then, he silently came in me. I guess he was too embarrassed to say, I'm cumming!
Once I realised he had cum, regret crossed my mind for the first time. I could have handled this much better.
Without helping all those guys trying to toss to my loss, I Immediately left putting my pants back on as I headed for the front door, for the final time. I slipped my top back on. My family wer all yelling at each other. I wasn't listening. I kept walking, got in my car, and without a word, drove away. My son was calling me before I was at the end of the street. I answered. I said, Harry sweetie. I am so sorry about all that. I don't know what I was thinking. I just had to do something. Harry said, Mom. It's ok. I still love you. You just walked in and saw them before yelling at me? He questioned, obviously trying to piece together how it happened. Harry. I failed to answer, saying. I no longer have a husband or a daughter. As of tonight, I only have a you. I promise to never do anything like that with you ever again and I understand if I've hurt you. No mom, you didn't hurt me. It was the most embarrassing moment of my life, but I am ok. I'll stick with you. Don't worry about me, I'm in my car driving around, looking for you. I'm worried about you. I told him where to meet me and went to a nice hotel for the night. Separate beds. I'm not sick, like you expected. Divorce time!
