Sex with sister in law

So my sister in law is hot, I mean my wife is also hot lol (they have good genes) but I always thought her sister was gorgeous and petite, she has small but decent boobs and a pretty big butt. Her sister is very playful and flirtatious and we would play around and insult each other from time to time.

Back in July we all went to Mexico on a vacation, their parents have a pretty big house out there. One day everyone was going to the city to buy some stuff but I there was no room for two people to go so everyone went except me and my sister in law. For the sake of privacy, we’ll call her Josie. We stayed back, I went upstairs to lay in bed and play on my switch. Her room is right across from ours, I heard her come up and go into her room as well. I was just laying there playing when I heard her door open, and she came and knocked on mine. I welcomed her in and she came over and asked what I was playing, I showed her and she said “that looks boring” (Kirby) lol. She climbed on the bed and immediately started rubbing my leg, I looked at her and she just said “you want to?” I hesitated to answer as I was processing what she was asking lol, she reached for my dick and squeezed and said “ I promise this is stay between us. I said fuck it and told her yeah let’s do it.

We started making out and she took off my shirt and licked my nipples and chest. She sat back and took off her shirt and was not wearing a bra, her tits are nice and perky, dark brown nipples, not very big but big enough. I sucked on them as she moaned. My room was upstairs on the side of the street with a perfect view to see if any cars were coming but also the city was a bit far and knew we had plenty of time. She pulled my shorts off and pulled down my boxers, I was already hard. She looked at my cock and said “wow that’s a pretty dick”I said “pretty?” She said “yes, you have a really nice dick. I always wondered what it looked like” she stroked it for a bit then she put it in her mouth. I’m gonna be honest, she wasn’t the best at sucking dick but it still felt amazing lol.

She sucked then would take it out of her mouth and make a face and say “ugh the precum” she kept sucking then she just told me “fuck me good please” she took her shorts off and her underwear revealing her petite shaved pussy. I asked what position and she said “I love to ride” so she straddle me and guided my dick inside her, she moved down on it very slowly as she moaned. Then she rode me soooooo good holy shit can she ride! She kept moaning and reached back to squeeze my balls. I grabbed her tits as she was riding, she then got into the squat position and started bouncing up and down, fuck she was so good, my wife has bad knees and can’t do it. She said she was close to cumming so she went back to riding harder and faster, I told her I was close too but she said “wait wait! I’m almost there!” I told her “wha if I cum?” She said “it’s fine just cum inside me, I’m on bc, but not yet, I’m getting close” she kept riding and she finally let out a big “fuuuuuuuuck” I felt her pussy just throb and felt the juices all over my dick. She then said “omg fuck that was so good! Now you can cum” she kept riding faster and faster, I felt it coming and I told her “shit I’m cumming, I’m cumming” she kept going and I let out a big “ahhhhhh” and dumped so much cum inside of her, one of the best orgasms I’ve ever had In a very long time! She felt my dick throb as it unloaded inside her, she kept saying “oh oh oh wow, that’s a lot” she laid on top of me for a few minutes and leaned forward on top of me with my dick still inside here. She looked at me and said “thank you I really needed that” I just said “thank you so did I” then said “don’t worry, this is between us.”

She kissed me and climbed off and stood up on the floor then said “look!” As the fun just dropped from inside her, she laughed and cleaned it up then went into the bathroom.

We haven’t fucked since then and believe it or not, it has not been awkward around her and we just dont really talk about it either, it seems maybe just a One time thing…. For now lol
