So this happened to me a while back ago and evertime I think of Lake Havasu this jumps into my head. my cousin and myself, have always been flirty since I could remember but nothing really physical until later. I'll post the story of how this started with her later. So this big group of people ( cousins, friends and others in three two different cars) decided to go to lake Havasu and I tagged along. It was a bit of a trip but we make it there eventually. All the girls we wearing these nice skimpy bikinis and my cousin wore this nice purple thong bikini and could not stop but to stare a bit even though there was plenty of eye candy around. So after a couple of hours later of fun and plenty of alcohol we decided that it was time to go home. But one of the cars was having issues and did not was to start. We ended up all cramming into one car and my flirty cousin jokingly said she would jump on someone's lap and smiled at me. So on the way back they started to blast some music and being that we were all very drunk and started to really get into it. My cousin started to dance and move around while sitting on my lap. I got rock hard instantly. She covered her self with a towel and really got into the music. She started to grind on me and I was loving every second of it. Some of the drunk people started to kiss and make out and sing and they really didn't notice my cousin grinding on me. By this time my cousin noticed that I was rock hard and she grabs me and fondles me a bit. We have always done stuff like this but not in front of people but since everyone was drunk caution kinda went out the window. She grabs my hand and pulls it up to her tits while still underneath the towel and my heart started to beat faster and harder. She whisper into my ear something but I couldn't hear her because of the music playing so damn loud. I asked her what, and she leaned closer to where I can smell the alcohol and weed coming from her and tells me she is really wet from all the grinding. I just smile and asked her to prove it (jokingly) and then moves my hand from her tits to her pussy and holy shit she was soaked. She then pulls my shorts down and pulls my dick out and puts it between her ass cheeks, it felt fucking amazing cuz she was still grinding and dancing on me. My dick was pulsing and throbbing between her ass cheeks and I couldn't really take it anymore. I began to use my hand to rub her pussy and she really enjoyed it and then I pushed her thong out of the way a bit and moved a bit down on the seat. When she started to grind hard, me my dick slipped inside her, she was in shock that I was inches inside her and I was in heaven. She turned and whisper into my ear "dude wtf?!," I replied that I couldn't help it and I just moved around like I was enjoying the music while thrust into her. Her face was red as hell and let out this Lil moan in my ear. I was loving every second of it. I whisper to her ear if she wanted me to stop and she replied that we are both going to hell might as well make it worth it and smiled and counting to grind on me. We kept moving and dancing and while Being inside her, God dam it felt amazing. Everytime I pushed in or pulled out I felt her pussy cling on to me. When ever someone looked in our direction we would just act like we were talking and dancing to make it less conspicuous even though I was balls deep in my cousin pussy. After a while she whisper to me that she is getting ready to cum and I was in the same situation. She screams at the front sear to turn up the music which they did and she grinded hard on me. I felt her juices flowing down my leg as she move and scream sang and I couldn't help it. I tried pull out but she felt so fucking amazing I ended up Cumming inside her. She felt ever oz of my cum shoot into her and I knew I was in deep trouble but i couldnt really careless at the moment. She turned to me and whisper that I'm so fucking dead. I replied with sooooooo fucking worth it and laughed nervously. She pulled me out of her an I just felt our cum ooze out of her dripping on to me and down my leg. I was happy as fuck and she was too but still mad that I finished inside her. She lights a joint and I light a cig to mask the smell of sex but the smell still lingered in the car. After we got back to our town, the driver asked who was fucking in the car cuz he could smell the sex a mile away and a couple raised their hands. My cousin and me were so into out own world of ecstasy that we didn't notice the other couple having sex in the back. So we just joked about it and let them take the blame. My cousin didn't talked to me for a couple of weeks after that but we started to talk again eventually. We joke about it every once in awhile between me and her. we would hook up when ever we would have large family gathering, we sneak away for a bit and just fuck until we finished and run back before anyone would get suspicious. I can share more of our hook ups if you guys want. I just felt like I need to share this moment since we are going back to lake Havasu this summer.
