I swear I thought this kind of thing only happened in porn, but here I am with an amazing/naughty/taboo experience.

A little background: My husband and I have been married for 12 years and together for 16. We met sophomore year of college and started dating junior year. I am 36, mom of 3, 5’7” chubby body type with dirty blonde hair and 40G bra size. My husband is 36, 5’11” 200lbs dad bod type with a shaved head and beard with 6.5”.

A little over two years ago my husband’s parents surprised us and husband’s sister and her husband with a family trip to an all inclusive resort in the Dominican Republic. They told us on Christmas and the trip would be the following Christmas week. Everyone was super excited and my sister-in-law and I spent at least one day a week meeting for dinner and planning the excursions we would do during our trip.

It all changed that May, when my sister-in-law informed everyone that her and her husband were getting a divorce. I felt so bad for her especially when she told me privately that reason they were getting a divorce was she walked in on him having sex with a man, and to top it off he was the one taking it up the ass. It was devastating, and there was nothing I could other than just be a friend who she could vent to. Her and I were going back and forth whether it would be good for her to still go on the trip or if it was better for her to relax at home and just re-center herself. By the time thanksgiving came around she had made the decision to go on the trip.

The time had come and we had an uneventful flight. When we finally got to the resort and were checking in we realized there was a mistake with the booking, and we only had two rooms instead of the 3. My sister-in-law was understandably not thrilled with the situation because she knew that she was the only lone person which meant she was definitely going to be the one forced to sleep in someone else’s room. That first night she chose to stay with her parents. The next morning she vented to me while eating breakfast about how bad her parents snored and how she couldn’t get comfortable because she typically sleeps in a tshirt and thong but didn’t want to make her dad uncomfortable so she wore sleep shorts a bra and and a long sleeve sleep shirt. That’s when I suggested that our kids go stay in “grandma and grandpas” room and she come stay in our room. Everyone agreed and that night the grandparents took the kids to get ice cream and then head to their room. My husband, his sister, and I decided to go to the bar and have some drinks. 2 drinks turned to 6 drinks which turned in to 10 drinks.

We decided to call it a night slowly making our way back to our room, giggling and laughing the whole way. When we got back to the room I went straight to my pajamas and without even hesitating just slipped my dress off leaving me in a bra and thong. As I realized what I had just done, I turned red with embarrassment, and started to apologizing profusely. My sister-in-law laughed and said it’s completely fine. She then proceeded to slide her dress off (she is 5’6” 140lbs jet black hair with 36DD). Her dress fell to the floor and both my husband and myself let out a gasp, because she wasnt wearing any panties or bras. I then noticed my husband staring hard at her, so I got an idea. I walked over to my sister-in-law complimented her on how well it went and a tip for everyone. I then started kissing her neck and letting my hands wonder around her body. My brother got beat red and nervous as he got closer I reached and grabbed his dick and pulled him to his table and from that point on the rest of the trip we had so much kinky/naughty/silly stuff lets get it done
