My wife Amanda and I are on vacation at a hotel and casino located on a beach.We rented a cabana and Brianna was our waitress, cute brunette college student about 22yo wearing a cute tennis outfit. She was fine, she had tan muscular legs and a nice build, she did a great job making sure our lunch and drinks got to us. We have had a few drinks and I started looking for a good match for my wife to wrestle, we talked to several couples who liked the idea but already had plans for the evening. while I was in the pool and Brianna brought me my drink over standing over me at poolside and smiled at me and winked at me kind of flashing me , showing me her panties under her skirt, I thought OMG,did that just happen. It was getting close to time for the pool to close and my wife Amanda was in the mood and was open for anything, so I asked her do you think you could take Brianna in a match and she confidentiality said that she would win easily.Amanda is 48 yo. With 42DD's. we all have been talking all day and joking around. we were tipping Brianna real good so she was making sure we got everything we needed. Amanda went to the ladies room and while I was closing our tab, keep in mind I have drinking all day and thought about how Brianna would respond to my request, would she be offended and have us kicked out. So when Brianna came over and asked will there be anything else, I asked her , do you think you could beat my wife in a wrestling match and she smiled , looked at me and said I would make her old ass submit to me.I almost fell out of my lounge chair,really. She said yes that her shift was ending and she would go get cleaned up and come to hotel club and meet us there. So when Amanda returned. I told her what I asked Brianna and told her what Brianna said. Amanda said we'll okay I'm going to teach her young ass about respect. I thought OMG, I'm going to have a great night. So we all met at the club about a couple hours later and had dinner and a couple of drinks, Amanda and Brianna were talking and joking with each other giving each other catty looks. I wanted to do go to the casino and play a little. So Amanda and Brianna said they were going to go up tp our room for a couple of drinks and go over the rules of their match. About a hour later I get a call from Amanda telling me to come up to the room. I could hardly wait. it seemed like the elevator took forever to get to our floor. When I came into our room Amanda was sitting on the edge of the bed wearing her purple bra and panties and Brianna was sitting in a chair wearing a wearing a white bra and panties. I almost passed out with excitement. So set on the couch and after pouring myself a drink. Both ladies smiling stood up and both got on the bed on their knees across from each other and their smiles went away and they both got serious looks on their faces glaring at each other. Amanda told me ringvthe bell. So I said ding ding, and OMG they came to get her like they hated each other both grabbing hair and rolling around on the bed giving each other body shots Amanda rolled up on top of Brianna and started smothering her with her tits. Some how after struggling Brianba managed to buck Amanda off of her, when Amanda rolled over on her back Brianna jumped on her bringing her knee up into Amanda's crotch and Amanda screamed out in pain, Brianna with her muscled legs wrapped Amanda's neck and started squeezing while grabbing Amanda's hair and jerking her hair back, and she said to Amanda submit to me, you old bitch. I didn't know what to think, watching my wife getting her ass beat. Amanda started crying and yelled out I submit, I submit. Brianna released her hold and shoved Amanda over on the bed. Amanda curled up rubbing her pussy holding her neck. Brianna said to Amanda remember our agreement and Amanda just groaned and just laid there in defeat. I was in shock I have never seen my wife lose like that. Brianna walks over to me and takes off her panties and unzips my shorts. I'm already hard , so she says to me you are my prize, so she rode me until atleast until I climaxed, the she got up off me and walked over to where Amanda was laying on the bed and said I'm not finished with you yet , Brianna sat on Amanda's face pulling her face into her cxnt grinding while Amanda was struggling to get away but with no avale.After Brianna climaxed she got up and kissed Amanda and came over to me and kissed me. I tipped her and she told us when her next shift was and left our room.I went over to console Amanda. She was crying and embarrassed that she lost and I told herthatvthatvwas the sexiest fight I have ever seen her in and I thanked her for fighting for me. I have a great wife. Seeing her getting beat and humiliated like that. I gave never asked her to wrestle again. Amanda did tell me shecwanted to wrestle Brianna again sometime. I asked Amanda why did yall attack each other like that hard and heavy, she said that Brianna and her just decided they would just go for it all and fight. I said damn.
