My hot sister in law and family vacation

Family vacations can be stressful affairs at times. Once a year we travel with my wife’s entire family. There is a total of 13 of us which can lead to some frustrating situations. For me one of the worst parts is that I would be spending the week with my sister-in-law. Her name sandy. Sandy is beyond attractive. She has the nicest ass you have ever seen. This is the type of booty that what ever room she walks into if you watch every guy is checking her out. On top of the booty her waist is tone, legs are long and has the smallest little tits. This has always been my weakness… big booty and small tits.  Sandy was proud of her body and wasn’t shy about showing it off. Between the skin tight leggings that hugged her ass tighter than any fabric should, tiny shorts where her butt checks just barley show, and skimpy cheeky bikinis she wore, and the lose tops the occasionally gave a nice few of her small tits, its always  a hard week trying not to get caught checking her out with so many people around. This trip was no different.

Her and I have had some interesting moments before that has and would have gotten me into trouble if I acted on them. One day in the past we were talking about her workouts and she mentioned something new was really helping her ass. Then she ask me to feel how firm it was. She did this right in front of my wife and her husband. I declined and she asked me 2 more times before giving up. All I wanted to do was to grab both cheeks as hard as I could but I wasn’t trying to get killed. I have seen her panties several time poking out of her leggings and to my disappointment they are always plain utilitarian thongs.  She confirmed her choice in underwear in my mind during a conversation around valentines one day. I made joke she should get this expensive brand of panties my wife likes for her husband for valentines and hoped my wife would do the same for me. She responded, “I don’t do fancy underwear, they just serve the purpose of catching crotch juice”. That statement both disappointmented me knowing that she didn’t like sexier panties and also sent blood flowing south thinking about her wet pussy.  I walked in by mistake on her changing out of a dress after church looking for my son and her dress was pulled down to her waist and she was facing the mirror. She only had those little gel things on her nipples instead of a bra. I shut the door and apologized through it. Later I apologized again and she responded, “no worries not like I have much to look at up here anyway, and gave me a wink.” She knows from past conversations around boob jobs that I much prefer small boobs. These events as innocent as they are drive me crazy.

On the third day of vacation my wife asked me to run down some laundry. When I got to the washer and dryer there was clothes in the wash so I started to switch them to the dryer. I knew instantly that this was Sandy’s family laundry. My heart started racing when grabbed a pair of panties. They were NOT utilitarian. They were a double string lace black thong. I found a pink thick lace thong, a tiny green g string and a pair of  blue basic thongs I have seen over and over. I was hard instantly. Knowing these were on her most intimate places had my racing and that conversation replayed in my mind and her words ” crotch juice” played in the back of my mind. With great effort I put them all in the dryer and went back up stairs and relieved some stress in the bathroom.

The next couple days I was beyond horny and could not stop thinking about her panties. Every time i saw her ass and panty lines through those tight leggings I was trying to picture which pair she was wearing.

Then one afternoon my wife told me she was wanting to shop with her mom and wanted to know if I wanted to come. I declined but to my surprise she took my son with her and the rest of her family but me and her younger brother who was at the pool left.

Once I realized I was alone I started to watch some porn and get rid of some of my sexual frustration. I kept picturing the shorts and ass sandy changed into before she left. Then it hit me. If she just changed, maybe she changed her panties too. I tried to push that out of my head but couldn’t. I walked into her room and peaked around and sitting right on top of a pile of clothes was a purple thong lace thong with a sheer see through material for the crotch. They were embodiment of sexy. My heart was racing. I tried to remember exactly the way they were laying to put them back. I told myself just one little peak and put them back. When I picked them up and felt the crotch they were SOAKED, and still warm, she just took them off moments ago. I mean these were how wet my wife’s would get after fooling around in our teens. I flipped them over and there was a small creamy spot and the rest was just wet, no color. I shoved the panties against my nose and took in the smell of her pussy. It was heavenly. I couldn’t believe how good she smelled. Then I sucked the creamy spot and all the juices out I could. I was about to burst. I put them back and went back to my room and came the hardest I ever had solo.

Then the guilt hit. I couldn’t believe that I crossed the line and invaded her privacy and felt I had cheated in some way. But what was done was done and I just had to deal with it.

That night after dinner we were all watching a movie and sandy sat next to me and threw her legs on top of mine and I was instantly hard. I was always attracted to her but I now knew what she smelled and tasted like and I could not get it out of my head. I was hoping she couldn’t notice and tired to keep my mind on the movie.

Sandy kept talking to me throughout the movie and somehow we got to talking about the house and it’s awesome Floorplan. She said the only thing she wished that had a bathroom in her room and not in the hall. I told her that it wasn’t a big deal. She then said it’s only a problem when I have to run into the hall in the middle of the night naked to pee. I am just praying noone is out here. It took me a second to process what she said and before I knew it I responded,  “well you can count on me to not be out here because my luck would never be that good.” I was in shocked that spilled out of my mouth and instantly looked at my wife to see if she heard but she was focused on the movie. I looked back at Sandy and to my surprise she smiled at me and said, “well I always sleep naked and always have to get up to pee each night” and she gave me a wink….
