This incident happened 3 years ago but it has really affected me and I think about it a lot even today. I was 16 years old then and my mom was 42 and dad 44. Both of my parents were working. I am the only child.
We had to shift to Mumbai from a small city because of my mom's promotion. My dad was still working in the other City and it was taking him sometime to get transferred to Mumbai. So that my studies will not be affected, mom and me shifted to Mumbai while dad was waiting for his transfer orders. Since my grandparents were not keeping well, dad finally decided that he will ask for the transfer after 6 months once their health improves.
During this 6 months, mom and me were alone in this big city. Mom did not know much about the people and office culture etc and was having a difficult time managing everything since dad wasnt here either. After sometime, she made some friends in the society and in office and then things got to be comfortable.
One of her friends was Nisha aunty. Nisha was a very smart lady. She dressed up for every occassion and was a head turner. I could see her having an influence on mom's thought process. Mom had also started to carry herself nicely. Also, she had started to flirt with some office colleagues in a friendly way just for fun. Nisha used to support her with this and both Nisha and mom were very open when they discussed these things at home. They even talked to me many times about getting a girlfriend and going on dates. I never had previously thought of my mom being so open about such things as she was quite conservative.
After around 5 months, one day my mom was very angry. She told me that dad had mentioned that it will take him another 6 months to get his transfer to Mumbai. I was also disappointed. Mom said this is because his boss was not ready to relieve him citing lack of replacement.
When mom told this to Nisha, she didn't say anything at that time. Later, I overheard her whispering to mom if this was really the case. Mom asked her what she meant. Nisha said, that since both you and your son are here, your husband must be having fun. He would be having a mistress and wants to continue having her for some more time. Her thoughts really started influencing my mom. She got quite angry, Nisha said there is a way to get back at him. She asked mom to come to her apartment at night when I was asleep.
I pretended to sleep but followed mom when she went to Nisha's apartment. I went in after her as luckily she had not locked the door behind her and hid myself behind the living room curtain. Mom had gone inside to the bedroom whose door was closed. Rest of the apartment was dark. After about 30 minutes, I wanted to leave because I was scared so I tip toed to the door. Suddenly I heard laughing sounds coming from the bedroom, curiousity took the better of me and I went close to the door and peeped in the keyhole. What I saw blew my mind.
Mom, Nisha and her husband were having a threesome! Mom was completely nude and on her fours on the bed while Nisha's husband was pounding her from behind. Mom was moaning and Nisha was standing close to her kissing her intermittently. They tried many positions and also at one time, mom and Nisha even sucked his cock. I got very horny on seeing the blowjob and immediately went to my apartment to relieve myself and slept. That is the day I learnt of my mom's secret.
I am not sure what I should do now. I feel it was wrong that mom cheated on dad but at the same time I feel that we make a very big deal out of sex. So what if she gave her pussy to another man for some fun. Definitely she didnt feel a man for so many months and was hungry for sex. Is a casual sexual encounter wrong? Even now both my parents have a good relationship and Nisha was moved out of the city one year back.
I sometimes fantasise about mom with her boss also. Is this wrong? What if she really had sex with her boss? Imagining her having sex with another man turns me on. Is it ok for me to continue with this fantasy?
Would love to hear your thoughts on this.
