Business Partners Wife

As an accountant I bought in partnership in now a three person office. The other worker is his wife. He was 45 and his wife 41 when I bought in. My wife and I married during college. We have a son and daughter. My wife works in a clinic paid 40 hours but seldom comes home before 10 pm most nights. I’m clipped so no more children for me.
At work one day a neighbor friend of mine saw my wife walking into an procedure clinic. I left work and was waiting when she came out. I didn’t confront her and the look on her face was priceless. We arrived home and she tried not to talk. I force in conversation reveal all or definite divorce. She admitted to having a work lover and even said this was her second procedure in 3 years.
I didn’t know how to process all of this. I went to work the next day and partners wife (Dara) knew something was wrong. I told her everything. She then shared how terrible it is to live with her husband. We both cried in each others arms. I knew how disrespectful her husband is toward her and me. She says it is worse at home. She said they they seldom have sex and she didn’t want to have sex with him anymore. He is overweight, lazy, and always smelling.
One day we had a deadline to complete he went home and his wife and I completed the task. When finished she came to my office and shut the door. She comes and sits on me me proceeds to give me a lap dance. We shortly were undress and had sex on the carpet. I hadn’t had sex since the discovery of my wife. It had been a decade that I had had sex with someone who really wanted sex. I cum inside her during her orgasm. The next day I didn’t know how to act toward Dara but she simplified things. During her husband 2 to 3 hour lunch break she came into my office again. Wearing a skirt that day she pulled it up and asked me if I like unshaven, partual shave, or bare. I chose partual so I could go down on her better. This excited her and she came and lay back on her desk and I went down on her. She almost hurt me during orgasms. She blew me. She said she hadn’t had that since her high school girlfriends sleepovers.
It hasn’t been hard to hide our having sex. Her husband doesn’t want to be around his wife. She may be middle age but jest that she is catching up with 20 years of seldom sex. Dara loves to kiss which I enjoy. She enjoys giving me blowjobs but favors me coming inside her. Dara is hooked on my eating her before most sex sessions.
My wife was recently fired. Apparently her affair with coworker was revealed. No sex since discovery day. She finally seems to understand her bad decisions. My wife stayed at home some weeks before getting another job. She started trying to be a mother but the kids are much closer bonded with me. I often see her crying, from guilt, loss of lover, or what her life has become. She dieted and got her figure back after gaining much weight during discovery. One Saturday she took the kids to my parents and came home and wanted to talk. Her lover broke up with her and his wife wanted to stay with him. She said they had been having the affair 9 years and it got out of hand. She admits to not loving me or our kids. She said she will get her love back if I stay with her. She even wanted to have sex but I turned her down.
I don’t know if my situation will blow up. I’m very satisfied with Dara keeping me satisfied. I don’t have any attraction for my wife and she knows it. I even hope she gets another lover because I like my sex life like it is. After the kids are grown I will most likely divorce. This lifestyle makes Dara and I feel we are revenging our spouses relationship toward us. Yesterday after work my wife wanted to try sex after months of no sex, but 30 minutes earlier I was zipping my pants after unloading inside Dara. Dara has a perfect sexy body and looks much younger than her age. I chose Dara any day over what my wife has to offer.
