Cruise Vacation

My sister took me on a cruise with her bf and two of his mates when she was 21. She told my parents that only her girl friends were gonna be there and I went along with it. As a teen, I was excited and had the hots for her bfs friend but kept getting ignored the first few days until one of the guys started talking to me. He was one of the guys uncle and was very muscular and bearded. We danced, partied, and got wet a lot and the uncle mainly took care of me while my sister went out and did whatever. One night we were partying and everyone had too much to drink and the uncle mentioned he would drop me off at my sisters room. When we walked in my sister was on the bed getting stuffed while giving her bfs friend a blowjob. I was so jealous and mad but the uncle told me that they were so drunk they were completely ignoring us or didn’t know we were there. I was so wet from seeing my sister taking two cocks so I told him to take me into the bathroom. He looked shock at first but then pulled me in and locked the doors and started tounging my pussy. I was super wet and started having the best orgasm of my life when I felt his scruffy beard on my pussy. He lifted me on the vanity and took his curvy veiny penis and plopped it in. I felt like I was gonna pass out but couldn’t move because he was stretching my legs all the way back. He came in me once but I could feel his heavy sack full of cum when his semen came in me. We were a mess but we put our clothes back on and decided to go back to his room. I couldn’t walk straight but thankfully his room was close. I slept with him that night and he fucked the daylights out of me some more. I tried giving him some head but he was too big so I let him slowly spoon fuck me when we woke up. We kept fucking in his room when everyone else lost track of us.
