Wife may be pregnant with trans [cuckold]

Over the past few months, my wife and I have decided to explore a new experience in our relationship. We were open to something different, and discussed the possibility of experiencing a dynamic that could fit into something like cuckolding or perhaps a threesome — although we're still unclear on the exact definitions and whether they actually apply to what we experienced.

After many conversations and alignments between us, we came into contact with a trans woman. She was very feminine, took regular hormones and maintained an appearance very close to what is expected of a cisgender woman — except for the fact that she had a male genital organ, which she was comfortable with. We had chemistry, and with the mutual consent of everyone involved, the relationship happened. She ended up having sexual intercourse with my wife, with penetration. It was intense, and both my wife and I reached orgasm every time. We repeated the experiment three times over the last month.

This morning, we received unexpected news: my wife is pregnant. Now, only through tests will it be possible to confirm the baby's paternity with certainty.

I confess that I am desperate about the possibility of not being the biological father. It's a delicate and emotionally challenging situation, which is really affecting me.
