This week my husband Marks nephew arrived with his friends from the Midwest. During Christmas when he and his family were here in Laughlin Nevada visiting us, he had asked if we could host for spring break in early March. We of course agreed, but limited to just 2-3 additional friends as we only had 2 guest rooms and a large game room to provide sleeping quarters for them. We also felt it would be more practical in our boat if we went out as it seats 7 comfortably in the sun plus a good size cabin in the central part of the boat. 5 in the back and 2 up in the open bow section. They arrived in Vegas on Monday and Mark picked them up as I stayed back to prepare their rooms. As it turned out just 2 additional guys were coming along with Marks nephew. When they arrived back at the house I had dinner ready along with cold beers as they all were 21 or older and wanted to get the party started. I hugged on Marks nephew Billy and he introduced me to his friend and room mate Travis and then to their neighbor at the student housing Burt. I hugged each of the boys but took special notice of Burt. He was one of those guys I would gravitate to when I was in college. He was lean and strong feeling with a big Adams apple and a deep voice with big hands. ( fyi since they are in school I changed their names ). Burt was the kind of guy that I would hook up with in college for just some occasional sex. They never disappointed as they were always well endowed and always ready at a moments notice to go multiple times. They were not the type I would be in a relationship with, as they were always on the prowl with the overloaded hormones. Mark took the most of the week off and as it turned out Tuesday was perfect for boating so we went south to Lake Havasu as its a bit warmer with lots of spring breakers there and lots of bars to go to along the channel. After dinner we sat around catching up with Billy and learning more about his friends Travis and Burt. My husband Mark had a lot in common with Billy and Travis as they are studying Aviation and Mark is an active pilot. I sat with Burt taking in the sight of him and reminding me of my college days. He was taking me in too, as he kept staring down the top of my loose T shirt and at my crotch in my short shorts. It made me a bit horny so I sat open legged and leaned over a lot. Soon I could see the affect I was having on him. As I suspected he was gifted and ready as I saw the nice bulge in his pants and I wasnt shy about looking. We finished up a few more drinks and surprisingly the boys were tired as they were on a different time zone and had a long day of travel. Billy took the guest room downstairs and Travis took the games room leaving Burt the remaining game room upstairs next to our room. I walked up the stairs as Burt followed me. I put a little extra sway in my step as he followed close and I showed him to his room He thanked me and hugged me goodnight and I could feel he still was quite hard as he pressed into me. I was getting wet at the thought of sneaking back there as I went to our room. When Mark arrived I jumped his bones and pulled his clothes off and he asked what has gotten into you? I told him what was going on and what it reminded me of in college as I took Mark in my mouth. I was working him till he was ready and he kept asking me if I was going to seduce Burt. I told him yes, but not tonight and laid Mark back and pulled off my pantyless shorts and climbed on him. I was riding him and having a loud orgasm. He was so hot from our talk that he came almost immediately and brought me to another orgasm with his mouth. I woke up first in the morning and pulled on one of his flannel shirts that button up the front. It was long enough so I didnt bother with bottoms and went down to start on breakfast. Marks nephew Billy was the next one up and was excited about boating as I prepared some potatoes and bacon. I could feel him looking at me every time I bent a little knowing my cheeky butt was probably visible. It was spring break so I know they would enjoy the sights. The rest of them all piled in at the same time and all of them were staring with my naughty husband Mark making comments every time I bent over.I finally laughed and said enough guys and lifted my shirt and flashed them my butt telling them they would be seeing this all day anyways. They all cheered and soon were gobbling down breakfast. Burt helped me clean up and was a bit touchy as he dryed pans and telling me how hot I look as the others were getting the boat loaded. I told Burt he is pretty hot himself and he reminded me of a boyfriend from college. He asked more about him and I told him we can talk more on the boat as I need to get ready. He smiles and says he can't wait. I went up and showered and trimmed my landing strip up and had to touch myself a bit but didnt finish an orgasm as I ran out of time. We drove south then launched and soon we were motoring to a sand bar to party at. All of us were drinking except our great captain Mark. By the time we got to the sand bar it was mid day and it had about 20 boats scattered around both sides of it. When I walked around the boat serving drinks, I could tell the guys enjoyed seeing my big boobs bouncing and looking at my thong cover ass jiggle. Now we could get off the boat and walk around the sand bar. Mark took the two future pilots for a stroll to see the girly sites I am sure and Burt stayed back with me. He asked me again about my college fling and if I missed it. I told him way more than I should and soon he was leaning in close. I couldn't help it so I let him kiss me which lead to him groping me then me groping him. I could feel the huge hard on he had and told him we needed to do something about this quick. I climbed on the boat as he followed grabbing my ass the whole way. I looked down the beach and about a quarter mile down the beach the other 3 were playing Frisbee with a group of guys and girls. I told Burt to go down below and get those shorts off. I waited a few minutes then followed him. He was hung like I expected with a huge pair of balls. His thick cock arched up to his belly button. He had a big angry cut cock head. I just sat on the couch in front of him and took him in my mouth. It was thicker than I have had in a while so took me a bit to take him all in my mouth and then I worked my magic and within five minutes had him spurting his first load in my mouth. He grabbed the back of my head like I thought he would and fucked my mouth and filled it with his tasty cum till it was running down my chin. I grabbed a towel and cleaned my face off and peaked out to see where they were. They were still at the same location down the beach so I told Burt to keep those pants off. He did and I told him to sit back as I stripped off my bottoms he reached out and fingered me while complimenting my landing strip. I got so horny I just climbed aboard. He was still as hard as ever and I lowered myself down till he was all in me and then it was my turn to ride. I pulled up my top and he bit on my nipples as he fucked upward and brought me to a loud orgasm and kept at it for a while. I am sure the boat was rocking and I was concerned the group would be returning soon when I heard someone climbing back in. It was Mark and we kept at and I asked him where are the others. Burt tried to get out from under me but I held him in place as I talked to Mark. He said they were still down the beach and he came back for more beers and to make sure Burt and I were having fun. I told him we are and then said aren't we Burt. Burt understood and said yes we are and started back fucking upward as My husband Mark watched. Mark watched for a bit and said have fun you two as he took some beers down to the others. Burt asked me if this is all cool and I told him yes. And that Mark loves when I am naughty. Soon Burt was fucking me deep and fast and we both came together. I climbed off and grabbed that same towel to mop up our mess. I pulled my top back into place as I climbed off Burt. I told him to stay there a second and he complied as I got my phone and snapped a few pictures so I could show Mark what was in me. I got my bottoms back on but I was leaking and a bit red from the fucking I just got. Burt pulled his suit back on and still had a boner. I told him we don't have enough time for another round but I will come in a bedtime and spend some quality time with him tonight and probably the rest of the week. Every chance we get. The crew made it back to the boat and we had a late lunch and a few more drinks in the sun. Billy sat across from me and was looking at my crotch as we chatted. I asked him if they had fun down the beach? He said he did but not as much fun as Burt did obviously. I smiled at him and asked if he needed a release from me too. Billy smiled and said he would love that. I told him when we get back this afternoon we will find a way to sneak away while they clean the boat. After our journey back, I told Mark of my plans to run to the store and gather up dinner and tomorrows drinks. He told to go while him and the boys clean the boat. I told Mark that I will be taking Billy. He looked at me and smiled and said ''have fun''. I took the truck to the store and lifted the center console up so Billy could sit close to me as we were driving. I told Billy to scoot over and feel these as I lifted my top. He mauled my boobs with his hands and undid the string on my thong on one side and played with me as I drove. When we got to the store I parked away from the store and told Billy to get it out. He pulled his suit down exposing a nice boner but nothing like Burts. I gave Billy a nice blow job and he finished in my mouth. I grabbed my shorts and went into the store and we loaded up. He was clinging on me like I was his girlfriend when I crossed paths with my neighbor. I introduced her to Marks nephew Billy and she winked at me as I smiled. I told her they will be there all week and she should come by. She looked a Billy and said that sounds like fun and is tonight to soon. I told Mindy that would be great. I knew it would be simpler to have a little help with the guys so I can focus on Burt and Mark tonight.
