Girl Inches [my sister’s man]

My sister Dani is almost 3 years older than me. We bonded more closely than any of my other siblings in part because of our closeness in age, our physical size, and our looks. ( plus she’s my bad ass big sister) She has short brown hair like me and much bigger curves. Let me explain…

At this time in our lives I was 24 and Dani was 27. I weighed 125 lbs where she was closer to 140lbs. My cup size was a full C or small D and she was an F!! There was nothing small about her except her height at 5′ 2″ tall. She was short, curvy and in fantastic shape. All of that with a huge personality to match.

I had been struggling in my marriage and Dani was the person I always called. She had been in a wonderful relationship with Juan for 6 years then and I desperately wanted what she had. We talked about everything from better communication, date nights, and our love languages. These talks were deeply personal and included the size of Mike’s penis. ( see my wedding night) Dani knew Mike was consistently to big for me but that was only was part of our marital issues. Years earlier she had offered advice on how to make his size more enjoyable and a better fit. Dani volunteered that she too had struggled with Juan’s size but now she couldn’t get enough. When I inquired further she said he was longer than her hand at nearly 8″. Looking down at my own hand I knew that she understood what I meant.

On Saturday night she called and said let’s go to the bar and have a girls night. You need to get out. I agreed, got ready and drove to her and Juans house.

The bar was packed and we were dressed for the occasion. All eyes were on us from the second we walked through the door. It felt nice to be appreciated but this was pushing the limits. We found a place near the back and the liquor flowed freely. I don’t think we bought a single drink. We talked, danced and were given way to many numbers. After just two hours I was more than buzzed and quickly on my way to drunk. Dani suggested that we head back to her place before I get sick.when we arrived she stripped me down to my panties and bra sat me on the couch. She left me there but quickly returned with an oversized tee shirt and waste bucket. She removed my bra and covered with the tee shirt. She layed me down and headed towards her bedroom. “I love you sister” I yelled before laying my head on the pillow. “Lord I’ll never drink this much again” my prayer started…

I awoke to the squeaks and squeals of someone getting lucky. Dani wasn’t holding back and soon I could hear barking requests. The “Fuck me daddy” really perked my ears as Juan’s rhythm increased. Clearly he was fucking her as requested, HARD!! The session was over after about 25 minutes as close as I could tell. I figured I would give them a few minutes and then ask Dani for some Aspirin. My head was pounding and what I needed was in her medicine cabinet. I walked down the hall as fast I could go ( not very fast) and noticed the door was cracked about half way open. I slowly peeked in and was about to knock when I saw my sister’s nose touching Juan’s stomach. His cock was nowhere to be seen. Not even a tiny bit at the bottom. I was so proud, turned on and grossed out the same time. There, was my naked shapely sister on her knees totally deep throating my brother-in-law.
This was wrong on so many levels but yet I couldn’t look away. I needed to see how she was doing this. I could barely get Mike’s tip and maybe an each in. Half way on a good day if he wasn’t fully hard yet. I was no prude. On most guys that I had played with in the past I could go down about three quarters of the way. On one or two I could go all the way to the bottom. My sister was quickly becoming my hero. I watch in amazement as she bobbed and sucked never taking her mouth off of him. Juan groaned loudly and Dani pulled away. She stroked Juan only a couple of times before he started to come.

From out conversations, I knew that Dani liked to swallow and she didn’t miss a drop. What caught my eye was Juan’s cock. Was I wrong to keep looking or to watch my sister pleasure her man??? Probably, but I had heard so many stories over the years and there it was, rock hard sticking straight out. The head just barely sticking through her hand. I WAS longer than her hand ✋ just the opposite way than I had imagined. He was like 5 inches and a little thicker than average. Dani had lost her mythical status as a head giver was just my big kick ass sister again. She must have been using girl inches.

Juan is still to this day a great brother in law and my sister will got a ruler 📏 that next Christmas. As for me, after getting some Aspirin the headache went away and Mike followed a year later.

Comments please. I’m trying to write good stories the only way I know how… from memory. I do take some artistic liberties but the events did happen. Thanks for reading 📚
