A Chance Encounter Over Coffee and Dogs

Married almost 20 years. No sex and we seem to be living a life of convenience.
I'm home every day and began running into a woman when I walk my dog. This led to coffee at our places which then led to..
Her name is Michelle, 50s like me, big tits, sorta big frame, but tight big ass. You'd definitely check her out if you saw her. We started bringing dogs earlier, drinking by 11 and she initiated the sex talk. I told her that it has been " quiet" lately. She grabbed my hand and, " we can take care of that." We did that standing intense making out grabbing tits and each other's crotches. I pulled away, I mentioned cheating and she pinned me against wall, one boob still out, she grabbed my head, not gently, I began sucking her nipple like a newborn, " bite it...yessss.." biting her nipple hard. As we regrouped again, " my husband told me to go for it if I wanted to and he'd watch if you were comfortable with that, he's actually surprised we haven't yet." My conscience was picturing the heartbreak of my wife. Told her I needed time to think.
She was a bit rough again pants down, cock jumping out as she sucked me completely. Standing, "dont think too long." Walking out my door.
The coming week we had our wine and beer and we planned the four of us for some grilling by pool and drinks.
My wife had met them, so it wouldn't be too awkward.
Wife was sort of a cunt, but we grabbed a bottle of wine and walked over. Michelle is diabolical! She opened the door, bikini, tits and cleavage obvious. Hubby in just a shorts no shirt. Wife was a bit taken aback, but was a good sport. We laughed drank smoked, wife was laughing and happy, hadn't seen that in awhile. Michelle mentioned swimming, turning lights to pool off. Wife eyes, she seemed so relaxed, our kiss was deep. Michelle dropped her bathing suit on patio, "last one in!" Seeing her tits bounce, ass cheeks splash! He slowly revealed his body, stepped out of his shorts, cock swinging, splash! Within minutes of being in pool Michelle and her husband were floating around with my wife between them, her head was back in pleasure as they kissed her and knew she was getting the fingers under the water. When my wife began sucking her tits, I knew we were in. I drifted over, hubby and me discreetly grabbed each other's cocks. Michelle knew, wife oblivious in bliss.
Soon inside, big mattress on floor, wife all over me. I was licking her pussy as his cock began to get close to her lips. She grabbed it and forced her face on it. As that went on, Michelle took my place. I sat back as my wife was in a threesome. She saw it was her, didnt care. I got in her ear, I think she wants your tongue too. Wife did not hesitate, " you have to suck him if I do this." He stepped up, cock inches from our faces. I licked it, it turned her on,she "do it baby" Me and hubby got into it on mattress as the wife' orally serviced the other.
Wife wasn't sure looking up at hubby putting his cock to her cunt, I, "Do it baby." Her head back as he was already taking her. Sitting back watching my wife get fucked was surreal, but her pleasure was erotic. We soon got them from behind and let them make out as we fucked hard fast intense body banging. My wife couldn't kiss anymore, hubby's cock starting to pump into her during her orgasm. We all relaxed, swam a bit. Got home, wife was all over me. Her thing she really got into was tasting Michelle on my cock as I ate hubby out of her. She could not wait to go again.
One Sunday, I went to store, came home to hubby fucking wife as she was licking Michelle's pussy. She called them as soon as I left.." Sorry couldn't wait" Face back in pussy. I think I created us three created a monster.
