Sibling Revenge

My husband and I had a family get together last weekend. We invited my sister and her husband to come over for a BBQ and pool party. We had also invited several family friends to join us as well. We were all having a great time by the pool, while my husband; James was manning the grill. My sister; Jill made her appearance stepping out onto the patio in a bright yellow string thong and bikini top. She is a beautiful woman of 42 years with long brunette hair, tanned skin, large doctor created double D tits. and a flat tummy. I am her senior by 2 years. I have the same natural C's that I grew. I have a little belly dancer belly.

Jill seductively walked her way through the line of lounge chairs surrounding the pool. She bent over in front of everyone to pick up a pool noodle. I could see her whole ass. The men had their eyes glued to her back side as my female friends glared at me to do something. I escorted Jill over by James at the grill. Jill's husband; Jim walked out on the patio and went straight to the pool. I went back to bar-tending for my guests. Jill set up a lounge near my husband. I glanced over once to see James applying suntan lotion to Jill's ass. A couple of the male guests had joined James by the grill and were all ogling Jill's assets. Jim seemed to be occupying the female guests attention. He is 39 and has an athletic body. His trunks were obviously a size or 2 too small and his bulge showed straining against the fabric. Jim was strutting and diving for the ladies.

I looked back at James, Jill was obviously talking about her boob job as she was touching her nipple area. The guys were enjoying the show. Everything settled down when the food was ready and we all sat down to eat. This was more like what I had envisioned for our little pool party. We all talked. James went back to the patio kitchen area to start making homemade ice cream. I looked over a few minutes later and Jill had joined James behind the bar. I thought they were standing a bit too close, but I continued to be a good host with my guest. I kept glancing over to the bar. I thought I saw the end of a kiss once. And then I could swear James was fondling Jill's breasts! I went inside to pee. When I came back out, all the guests were playing volleyball in the pool. I looked over at the bar and no one was there. I walked over and heard the sounds of grunting behind the bar. I stepped around the bar. Jill was laying on her back with her legs wrapped around James hips. James was pounding her pussy with his hard cock. I watched in disbelief. I could think of nothing else to do, so i jumped into the pool and started playing volleyball with my friends.

As the afternoon became evening, the guests all left one family at a time. Jill and James were nowhere to be seen. Jim and I were floating around in the pool. A giant twinge of jealousy flew across me and I began to flirt with Jim. I dived in the pool and dropped my bikini bottoms. I ask Jim to help me find them. He dared me to jump off the diving board bottomless so I did. I had just shaved my pubes bare. My little pussy hid in the little crease of my crotch. I could tell that Jim was interested. I asked him to dive in bottomless. He climbed out of the pool and dropped his suit. His cock stood straight out. I ask him if I did that. He smiled and nodded. Jim dived in and swam underwater to me. I felt his fingers playing with my labia. When Jim popped up out of the water, we embraced face to face. He kissed me while releasing my bikini top. Jim guided me to the pools edge and sat me on the side. I dr*ped my legs across his shoulders and enjoyed the pleasures of Jim's tongue. I wanted his cock inside me. I motioned to a lounge. As I lay down on my back, Jim mounted me and I was in heaven. We fucked for nearly an hour before Jim pulled out and launched his cum across my belly. At that point, I didn't care at all about James and Jill. I didn't care where they were or what they were doing.

Awhile later, we joined James and Jill in the house. They were laying on the couch watching television. I grabbed Jim by the arm and led him down the hall to the bedroom. Jim lay on top of the covers on his back. I climbed aboard and rode him cowboy style. I looked back at the doorway to see Jill and James watching. Jim and I put on a great show for them. When Jim yelled out he was cumming, I jumped off and shoved my mouth over his cock. I sucked hard until I felt the warm goo and tasted the musty and salty cum. I swallowed it all. We collapsed and fell asleep. We we awakened, James and Jill were performing for us in he spare bedroom.

I have got to say revenge fucking is sweet on the tongue!
