Hey everyone, first time submission, long time reader, decided to tell a fun story about a weekend trip to vegas. I guess what made me post was this guy recently text me and wants to fly me to Seattle to see him and made me think. So anyways, a little about me, I was 24 this was 3 yrs ago 5’3 about 140 lbs, not skinny not fat. I posted a pic to get a frame of reference. I decided to go with my sister, her husband and his friend to vegas for a weekend after my break up. I had met his friend a few times and were fb friends, but nothing more than that. I had always found him really attractive, big black, muscular, handsome. I get to my sisters house and we’re all there talking a bit, gathering our things to go. We live in San diego, so it’s about a 5 hr drive nothing too much. The drive was okay, nothing major just a casual drive with talking, stories, jokes things like that. We get to vegas about 3 and check in to our room at palazzo, which was super nice. We all decided to share a room because it would be cheaper w 2 beds. We decide to do a bit of day drinking and then dinner and a show, then drink and gamble some more. The night goes as plan, and as the night goes and the drinks flow, my flirtatiousness becomes more apparent. I had always found the friend (Marcus) attractive, just never pursed anything. The night goes as planned and by about 10, we’re all pretty buzzed. Marcus has become much more flirty, caressing my back, occasionally my ass. I laughed and giggle as he did, but didnt bother to move his hands. He would do it discreetly too, which was fun. We decided to hit freemont street for a bit. Me and Marcus decided to walk the strip while my sister and her husband gambled a bit. The flirtyness was full on, was grabbing my ass, kiss me, caress my back. We go back to my sis and they’re done gambling, we decided to hit one last bar near freemont for a drink and some dancing then back to the room. We’re at the bar, me and Marcus sit on the back couch a bit while my sister is outside w her husband having a smoke. I started dancing on Marcus a bit while he sat, he lifted my skirt a bit and got a good view. I pulled down my skirt and sat next to him,laughing, he said that he loved the view. My sis and her husband came back in and were arguing w security because my sis was too drunk and were telling her to leave. They wait outside as I close the tab. We got back to the room and my sister was so wasted, she fell on the bed and passed out. I decided to shower cuz I had been sweating a bit from the heat. I come out and prett much everyone is in bed, my sis is snoring super loud and it seems that her husband is too. I get in the bed with Marcus and we look at the other bed and watched TV for a bit, he turns to turn off the lamp that is on the night stand, the only light in the room is from the TV.I laid on my side facing the other way and he spoons up behind me. He stated to caressing me and touching me. He kissed me and put his hands in my shorts and started touching. I was so turned on, but nervous and scared of getting caught with my sis being in the other bed w her husband. We looked over and made sure they were asleep. He took off his shorts and I took off mine. We laid there on the bed bottomless making our. I told him that we should just make out nothing more and he said okay. We made out for about 20 mins. I reached down and started stroking his already hard dick. He had the biggest cock I had. He was about 9 inches. I told him I was a bit tired and he hugged me and kissed me. I turned around to the spooning position again. I felt him rubbing the head off his cock up and down my soaked pussy. He slid it in from the back, i told him we needed to be really quiet. We started doing that for a bit, really slowly. I was lightly moaning, but we still had the TV on as well. It didn’t help that the bed was super loud and squeaky. We do it like that for a bit then he tells me to ride him. I was hesitant, but super horny and wanted him so bad. We looked at my sis again and they were snoring. I got on top of him, and had to ride him really really slowly, which felt so good. He had his hands on my ass, slowly guiding me. I ended up turning around and facing the TV and rode him like that. The bed got super loud, I was so nervous. I ended up getting off him and we went back to spooning. He finally came after about 45 mins because we were both going so slow. My sis and brother still sound asleep. The next day, Marcus text me that nick (my brother in law) heard us. I was so embarrassed. Marcus said nick didnt know whether to get up or move to let us know he wasnt sleeping, or just say there because he didnt want Marcus to not get some. I was so embarrassed tho. My sis obviously found out and now it’s a joke, which made it easy to get over the embarrassment. Anyways we actually dated for about a year after this trip until he got a job in Seattle about 11 months ago.
