We (32M & 31F) live in Toronto area of Canada. My wife’s elder sister (33F), married with 2 kids, is in an unhappy marriage because of joint family issues and does not get the right support from her husband as well.

Because of all the drama, she decided to visit her sister (my wife) for a couple of weeks. All 3 of us gel along and always picking up on each other (not in a sexual way).

One of the weekend days, my wife was scheduled to go to work and we were home bound as we had our evening planned that particular day in Niagara Falls. While she was away, my sister-in-law (SIL) decided to join me and together we started watching Crazy Stupid Love. Just in the beginning when Steve Carell is blabbering that his wife was pounded by David Lindhagen in a bar, my SIL paused the movie and asked have you ever cheated in a relationship, my response was a “WHAAAAA” and she turned away by saying OK and resumed the movie. I snatched the remote from her and asked her the same question but the next thing I heard shook my senses. She said “considering what’s happening in my married life, I might give it a try”. I was like why don’t you leave him then and move with us here in Canada. She was not sure as she had to think about her kids’ future as well and all the societal norms too. I understood what she meant as the kids are too young to understand what separation is. I asked her if she wants to be set up with anyone, I can arrange here and she laughed and said why don’t I start with you. The moment I heard this I started seeing her in a sexual way. I don’t know what got into me and I pulled her towards me and gave her the best kiss of our lives.

Our tongues were playing all kinds of games in each other’s mouths. We did not even care of catching our breathes and was just so involved in each other that time just stopped. Next moment, I know we are on each other butt naked and she is grinding me while I have my hands busy caressing her firm breasts. She was feeling me with her hands from my chest, shoulders and then to support to adjust herself on going down on me. I got the best blowjob of my life, it seemed she was hungry and sex deprived, each stroke rolled my eye balls and I was entering a divine state altogether. I don’t know how many times I came on her, in her mouth but I was just enjoying it all.

It was my turn to be on top of her now, I started with long kisses then going down slowly on her neck, collarbones, cleavage and then played with her breasts and started teasing with small licks on her nipples. As she was getting restless, I gently inserted my finger in her pussy. She was dripping wet that moistened the bed. Her moans was turning me on so much and I started licking her vagina and eventually ate her out. I could see her eyes closed, pinching her nipples real hard and with her head’s support trying to get up in enjoyment. She was screaming my name at the top of her voice and that made me rock hard. She asked me to slide it in her raw and I obliged. I had such a great feeling to put it in without protection and it slid so easy with all the natural lube of her wet pussy and my rock(star) doing all the action.

We fucked in missionary & doggy and eventually after I came twice, we just dropped dead on the bed and fell asleep. I don’t know how long we were involved in it but woke up together to my wife’s phone as she was leaving in few minutes and be back in an hour’s time.

We took the shower together and teased each other a little bit but got dressed and waited for wifey to come back. Our secret did not last long as I will narrate the next segment shortly (if I get good upvotes lol).
