I guess I hadn't locked the bathroom door because I heard it open. Whoever it was would figure out someone was in the shower and leave. I had shampoo in my hair and my eyes were closed. I heard the glass door open and someone stepped in to join me. I figured it was my boyfriend but he usually wouldn't make a bold move like this one. I felt hands on my ass then they made their way up to my boobs. He squeezed my 36C breasts. I let the water rinse the suds out of my hair and my face. He moved up close behind me and I felt his cock between my ass cheeks. His very large cock. It was then I knew it wasn't my boyfriend who is just average in size.
I turned around and looked at my brother. He was smiling at me as he pulled me close. I asked him in a whisper what the hell he was doing, we could get caught. He said he had locked the door as he began to kiss my neck then my ear and finally my lips. It had been 8 months since we had last been together. We used to have sex a lot and I missed it. I felt his huge hard cock between us. It had been the first one I had ever fucked. We got re-familiar with each others wet bodies as we kissed. He turned me around and I bent over for him.
He rubbed his big cock head against his sister's wet slit. My brother started to push it in and I held my breath. His desire for me was great but he took it slow for now. I arched my back as he started to slid in. He had one hand on my hip and another on my shoulder. He continued pressing in and finally hit bottom. He is at least 9.5 in long and can't get it all in me all the time. As my brother started to stroke in me he said how tight and hot my pussy was and how much he missed being in it. I missed him being inside me too.
He was fucking me like he always does, full long strokes of his fat long cock. The big head would hit bottom pressing into my cervix flattening it. I wondered now how I would ever be satisfied by an average cock, one like my boyfriend has. I told him to hurry because we had been in here too long. My brother was about to cum in me once again. I wasn't going to stop him even though I knew I would be ovulating in a couple of days. This was risky but I wanted him too.
He had both hands on my hips now driving hard and deep. I had my hands on the wall in front of me to steady myself against the onslaught. Just as we started to run out of hot water I felt his cock swell even bigger inside me. He stopped stroked and I felt it jerk and start to unload. My brother was cumming in me. His loads were always huge and this one was no different. On and on it went filling me up. The feeling got to me and I came as well. My pussy clamping and milking his cock. His cock finally slowed down and stopped shooting. It still felt huge in me as he started to pull it out. Once out he turned me around and held me close. I was glad of that because my knees were weak. I felt his load start to pour out of me.
He gave me a kiss and then got out first to dry off and try to leave un-noticed. I washed my pussy as best I could and got out too. I wrapped a towel around me and waited a few minutes after he left. I made my way back to my room and didn't see anybody. Since we were at the lake I just put my swimsuit on. It was a little black bikini and was actually from last summer. As I adjusted it I saw that it was really too small. My boobs had gotten bigger and were spilling out some. It wasn't a thong but since my ass had become shapelier it rode up between my cheeks. I looked at myself in the mirror and thought I looked pretty hot. Maybe part of that was because I had just had hot sex with my brother, but I knew I would get lots of looks wearing this. I made some final adjustments to my top. I have fairly large areolas and the two little triangles of fabric barely covered them. I thought there was going to be a pretty good chance something would fall out but I wasn't going to worry about it. I went to the kitchen to get some breakfast and everyone was in there. My boyfriend gave me a kiss on the cheek and when I made eye contact with my brother he winked at me.
I was at the sink when my mom stood next to me. She whispered to me asking if I thought that the bikini I was wearing might be a little too small. I whispered back that it was from last year and was the only one I brought. I saw my dad look at me and then frown. Always the protective dad, he didn't like his little girl showing too much. I grabbed something to eat and then went outside onto the deck. It was two levels. The upper level had the outdoor cooking and eating area and the lower deck was built around the pool. There was a pier that led down to the boathouse where our boat and a few others were tied up. I got some sun by the pool until about noon. I went to get something to drink and found my brother. He asked me what the plan for the afternoon was. I told him that we could take the boat out and go over to Party Cove. It was an area of the lake where big boats would anchor and tie up to each other forming a big floating island. A girl friend of mine's dad had a big party boat and she said it would be there and she invited us to come party.
He said that sounded like a great idea. I told him to get the keys to the boat and find out who else wanted to go. I found my boyfriend and told him that we were taking the boat out and going to meet up with some friends. We went down the the boathouse and my brother was releasing the boat. They would be six of us going. My brother, three of my male cousins, my boyfriend and me. I was the only girl. Our boat was a Master craft ski boat. My brother was driving as we pulled away from the dock and headed out to the open lake. We cruised along and the spray and wind felt great on this hot day. We went through an area of the lake that narrowed. The water here was always rough from the big boats wakes. I had been leaning back with my eyes closed enjoying the ride when we went through some bigger waves. The boat started to bounce more and I heard some chuckling. I looked around and noticed my cousins smiling at me. I asked them what the hell was their problem. They just pointed at me. At my chest actually. I looked down and saw that my left boob was completely exposed. The bouncing of the boat through the waves caused it to pop out. I called them all horn-dogs and put my hand over my nipple. I think my brother was purposely trying to make the ride as rough as possible. I managed to tuck some of my boob back in my top.
Just as I thought everything was going to fall out again we made a turn and entered the cove. I looked and saw all the boats. They were tied up in four rows. There had to be at least 200. The biggest boats were in the last row and right in the middle of the was my friend's boat. It had to be the biggest one out here. It was well over 40 feet long with multiple decks. It really belonged on the ocean or a great lake instead of this lake. I guess if you had the money and liked to party then you needed a big ass boat like this one. We got within about 20 yds of it the anchored our boat. We swam over to it and climbed aboard. We were told to go up the stairs to the next level, that's were the party was.
When we got to the top I could tell there was a hell of a party going on. It was a big flat deck and there had to be at least 30 people up there. The music was loud and people were drinking and dancing. Someone handed each of us a beer. I looked around for Sheri my friend. As I did I noticed something. Most of the women were topless. I recognized some from school but others were older. Even though my top barely covered my nipples I felt overdressed. I saw Sheri over in a corner. She waved me over. I noticed she was sitting in a man's lap and like almost all of the women she was topless. Sheri had A cup boobs, much much smaller then mine. She did however have amazingly puffy nipples. They always looked very distended and swollen, like little boobs on top of boobs.
I walked over to her and she introduced me to the man who's lap she was sitting on. It was her father. His name was Bob Evans and he owned a few car dealerships in the state. He had divorced Sheri's mother a few years ago. Sheri told me that he takes this boat out here to party cove every weekend during the summer. He likes the younger crowd and obviously likes to show off his wealth. I guessed him to be in his early 50's. He was shirtless with lots of gray chesthair. I would describe him as barrel chested, but in good shape overall. Sheri was sitting in his lap wearing nothing but a tiny thong. Her arm was around his shoulders and one of her nipples was pressed into his chest. There had been rumors that she was having sex with him. As I was introduced he took my hand and kissed it.
As he looked me up and down standing before him he asked me how I liked his little dinghy. I smiled and looked right at his crotch. Either from Sheri squirming on his lap or him looking at me I saw a nice bulge there. As I looked right at it I said it doesn't look so little to me. He laughed and said no the boat, how do you like the boat? I said it looked really cool, but I hadn't seen much of it. Mr Evans then asked Sheri to take me on a tour so I could see it all. Sheri gave her daddy a kiss on the cheek pressing both her nipples into his chest and then got up and took me by the hand. We went down a different flight of stairs into a big room that she said was like a living room in a house. We walked through the large galley area to another flight of stairs that led down to the lowest level. This was were the staterooms were. There were 4 small ones and at the end of the hall a very large one. This was the master suite. I asked Sheri which of the smaller rooms was hers. She looked at me and said that none were. She always stays in this suite with her daddy. It was then I knew.
I came right out and asked her if she was fucking him. She giggled and said yes. I asked her how it was. She said it was great. He was good in bed even though she had to work at getting his cock hard sometimes. I said from what I could tell it was big. Oh she said it is super thick, much thicker then any other guy she guessed. She said fucking him has it's benefits.
