Not married at the time

I've not found my soulmate as yet, but I've had relationships no wife among them. Anyway, I 27 do okay with women usually, just haven't found on to marry as yet. Anyway, I moved to the city and already well off and having a great job. I bought a house with 3 bedrooms and a single bathroom and attached double garage. I was settled and not in any relationship at the time, I got a call from my sister 30 (only sibling). Her mother-in-law 52 (mil) had a problem, her apartment building had a fire and was wrecked and would be later pulled down. So, her mil needed a new place asap and my sister thought of me, having 3 bedrooms I could put up her mil (widow) for a short time. Which I agreed to do, mainly because I couldn't think up a good excuse why I couldn't. I'd only her mil a couple of times sister's wedding and the Christening of my niece. But she seemed nice enough and I didn't expect her to stay long anyway. I was wrong as that was early 2020 and the Covid pandemic changed everything. Short version being in lockdown together we got bored and started fucking and so she is still living with me today. But I'm now married to my sister's sister-in-law 24 youngest of 3 and only girl. She came to join her mother living with me and as I was already fucking her mother, I started fucking her as well. She arrived during the lockdown by special permission due to a storm damaging her previous place and everyone needed to relocate. I got the daughter pregnant and to save problems we married, but I was happy with marrying her and still fucking her mother as well. Now we have 2 children and 1 on the way, already added 2 bedrooms to my house. One being the new master with Ensuite, we share with my mil. My sister has 4 children as of now and has said that was enough, but she said that at 3. My wife likes having threesomes with her mother and me. I found my soulmate.
