Continuing my updates, which have taken some really intense twists and turns.
 I (28M) and her (29F) ended up being making an orgasmic good morning because I got to cum inside her, We both did have more of these moments and stay overs, where we both certainly outdid ourselves in worshipping as well as destroying each other. Her husband was back in town, we decided to catchup every chance we could. We all watched a movie and spoiled ourselves with some shopping.

While having dessert, she broke the news to me that she's pregnant. I felt like it was just me and her sitting there, while I felt the ground slipping under my feet. In a fraction of seconds, I noticed that the husband is here too and I acted surprised and in awe as I remembered that they were planning to start a family.
We ordered some more dessert while we went over the medical reports and she talked on how I will be spoiling the little one.
It was a never-ending topic of discussion and we did discuss about some countermeasures as it is the time to be careful. One evening when we went to drop him at the airport for his next tour, she let me in on a secret.
She told me that right after our last round, when her husband was back home at night, they had sex like never before. The discussion of starting a family was in the books anyways, but she always was concerned about his performance. She made him believe that he has improved on a much better level, but the reality was... the sperm count was good and but the sperm health wasn't. He is not aware about these reports as he's quite sensitive to this information.

Which means... the baby is Mine. What's surprising? Is that she doesn't mind at all. She knew about her husbands performance but just does not want to hurt him in a way he can never recover from. I asked her many times to confirm and every time the answer stayed the same. In her books, its a win-win situation, as...
1. She doesn't have to damage her husband's manhood as well as personal issues, publicly(amongst parents) or personally.
2. Her health as well as the little one's entire care will be looked after me, since he's away most of the time.
3. According to her, our secret will stay hidden forever and won't be hampered legally as we did come to an agreement that this secret will never go out until our last breath.
4. Also, she said if I can't be her husband, I get to be her addiction, her escape, her unseen pillar and her inescapable desire.
