I had never had a threesome, never even thought that I would want to have one. I cant say about Mike and mom, perhaps the thought had entered their minds at some point in their lives. But here we were. I am not sure how exactly they felt but the smiles on their faces seemed to suggest it was to their liking.
To my utter surprise my feeble distracted blowjob had actually gotten Mike hard. He rolled over on to his back. I just knew what he wanted. I grabbed the lube out of the dresser and slathered it on his cock and got a dollop in my ass. As I lowered myself reverse cowgirl, his cock inching into my ass, I could see my mom's eyes widen. How she had gone this long without anal sex was beyond me but I guess I was still proud that she was open to learning new tricks. As I reached all the way down his cock, I paused to savor the sensation.
"You have 2 weeks to work your way up to this Jan. I am not going to wait longer."
"By the looks of it, I wouldnt want to wait longer either!" mom replied gamely.
She then did something that caught both of by surprise. She got back to placing her lips on my clit and inserted two fingers into my pussy. I guess she remembered that Mike likes that sensation of something rubbing his cock while he is inside me. Having this new sensation was new to me to too and a lot more overwhelming given that my earlier orgasm had left me a little sensitive already. Neither Mike nor my mom were going to let me get up so easily though. What followed was a beautiful experience, three people becoming one, connected so intimately. This was of course a physical expression of our mental states as well. Both mom and I had fully committed to Mike and each other in this new strange relationship.
It was at this point that I would say my mom fully transitioned into being Mike's wife and mine as well. That as I look back is the piece that most people miss. It is not just that we are both wives to him, as if one of us werent enough to give him what he needs, we were fully committed to each other as well. It isnt that we didnt share a bond before, we were very close as mother-daughter before. But what we share now is undeniably special.
Are there more adventures to share where we push each others boundaries? Yes, but those are truly beyond the point that my mom became my co-wife. I will likely continue to write them here as future parts so that those familiar with us three can follow but it is important to acknowledge to you, the reader, that the titular transformation was now complete.
