Not What I Expected

Jessi and I hooked up in High School, and quickly became a couple. All the usual experimentation and I knew I found my sexual soulmate. Although Jess is a big girl, we had a fantastic sex life and I think that got us through some hard times, including when my Mom passed. Mom left me the house ( small but paid off) and shortly afterwards I proposed to Jess. We were married at 22 and 2 respectively and I went to work for a large company in IT and Jessi worked locally at a big box store. Then COVID hit. I started working from home, and Jessi was working extra hours and getting a lot of overtime at the store. Near the end of '20, she broke it to me that she was leaving me for her true love, a girl from work named Lori! Jessi moved out and started divorce proceedings quickly.
Even though Jess had moved into Lori's apartment, we still were getting together once or twice a week for what we used to call a smash n grab, after sex we would chow down on ice cream or something and pass out. The sex was still great , but it was different. After the divorce was finalized, Jess broke it to me that Lori lost her lease and they were going to be homeless, could they stay for a while, and truthfully, I still love her and said ok.
BIG MISTAKE! Jess now identifies as a lesbian although she's obviously Bi, I'm straight although she has pegged me a few times, and Lori doesn't claim to have a preference, she calls it submissive pet. So here we are living as some sort of threesome thruple sharing chores and bills and Jess is now the power in the house. We share my king size bed, with Jess in the middle because she forbid Lori to sleep on the couch any more. Sex is not what you'd think. Jess and I can smash, then she calls Lori in to clean up. I have almost zero sexual contact with Lori. It's very stressful when they're in my bedroom, door closed and I'm working, trying to keep some music playing when I'm on calls.
The closest we came to a threeway was when Jess was on top of me riding, and forced Lori to kneel on my arms and kiss her as they faced each other. This put her pussy right on my nose and Jess told me to eat her out. Lori kept squirming away but eventually gave in and rode my face until she came. I was almost there when Jess hopped off, grabbed Lori's hand and helped her stoke me until I came, then they jumped in the shower, leaving me in the bed alone.
It's been a year, they seem to have no desire to look for another place, and my friends and neighbors think I'm living the life! It's complicated!
