Brother and Sister find out about themselves

We went to school the next day like nothing had happened. Leslie and Mark had planned to meet at his house for about an hour then come to our house. We had basketball practice today though. We just took the girls with us and they watched us practice until we went to the showers. We flew through them and left as quickly as we could. Ashley and I could barely get in the door before we flew up the stairs to our rooms. She began to undress to take a shower because she was hot from the gym, except this time she didn’t close the door to the bathroom. I was already nude watching porn and I saw a glimpse of her ass as she stepped in the shower. I heard the water start….this was my chance that I had been waiting for all week long. I walked into the bathroom and thank god my sister was turned the other way. I snuck up behind her and opened the shower door and stepped into the shower with her. I grabbed her ass on the way in and she jumped because she was surprised. 

She turned around facing me with her beautiful body that I had never been able to touch. She immediately noticed my hardon since it was at almost chin level for her. She instantly began sucking on my cock. It was the best thing that I had ever felt in the world. I was very surprised to find that she could deepthroat a cock, especially mine. She had a little trouble at first and was only able to suck about 5 inches until the got used to my larger dick and she took the entire 9 inches in one thrust forward. The water was rolling off of her tits as I began massaging them as she sucked my cock. Her nipples then grew to about an inch long and became hard. I then told her that I was about to cum but she ignored me as my cock twitched and 9 loads of cum were released into her mouth and she swallowed every bit of it. 

She then stood up as my cock softened to about a 7 inch erection. I gave her a long passionate kiss with plenty of tongue gathering the dots of cum she missed. I then moved one hand toward her bush of hair. The aroma of her pussy was great. I teased her pussy with my fingers until she quickly squatted onto 2 of my fingers, pushing them inside her. She was so warm and wet. I began fingering her first with to fingers and moving to four eventually. She cummed within minutes and I gladly sucked her juices off of my fingers. 

She then asked me to do the one thing that I had yearned for…to fuck her. We turned the shower off and walked out into my room still soaked and I lay on the bed. She then straddled my cock at first teasing her pussy with the head and then finally pushing it in. From the looks of it, it didn’t seem that she could take but about 5 or 6 inches of my cock but only if her pussy could handle the enormous girth. After gently riding about the first 3 inches of my cock she started moving farther down. I could feel her pussy tightening around my cock and she cummed after taking about 5 inches of my cock. She couldn’t handle anymore of it without the pain becoming too great, but she kept going. She made it to about 6 inches and she screamed because her pussy was too small. She slowly rode the 6 inches for a few minutes not going any further and her pussy started to relax. She then told me that she couldn’t take anymore of my cock, but I told her that she could. The entire time I had been able to keep from cumming to avoid making my sister pregnant and I still was. I then grabbed her ass and began sliding her along my cock faster than before slowly moving her along it with each thrust. She reached about 7 inches when she cummed again. 

I couldn’t wait to get my entire length inside her any longer, so the final thrust brought 2 inches of my cock inside her and she screamed and cummed at the same time. Her pussy was great because it was so tight around my cock, making it harder for me to avoid cumming. I then let go of my sister and let her ride my cock. It was an amazing feeling. She moved up about 8 inches of my cock each time and we back down. It was all I could do then to keep myself from cumming into her. I told her that I was about to cum and for her to get off but she held fast at the base of my cock. She had an orgasm and her pussy tightened around my cock, triggering my cum. I blew 14 loads of my hot sticky liquid into her pink pussy before stopping and my cock softened to about 7 inches. 

We heard a door close downstairs and then soft unmistakable moans of Leslie. We figured Mark and Leslie were here They couldn’t even wait to get upstairs before stripping each other. Mark walked in carrying Leslie on his cock while she was pumping him. Mark threw her on the bed releasing his cock from her pussy. He then jacked off all over Leslie covering her with cum. She and Mark quickly began cleaning it up. My sister then pulled herself off of my cock as it swelled back to its 9 inch length and laid her gorgeous body on my bed. She then spread her legs wide and I knew what to do. I moved in towards her pussy and I could smell her sweet aroma. I started by kissing around her blonde bush and moving my way down towards her pussy. I licked the around her pussy teasing her until I moved in for the meat. I at first only licked at her pussy until I became more aggressive and I shoved my tongue into her pussy. Her juices tasted so great. It didn’t take her long to cum. Now Mark and Leslie were fucking again except this time Mark was in control and he as thrusting his cock into her pussy. I began doing the same thing to Ashley with my massive cock. I cummed again in her pussy except with only 11 loads this time. 

Mark cummed in Leslie and pulled himself out of her. Leslie then proposed the idea of seeing how much Ashley could take since she could take my massive cock. We then switched places with Mark and I at Ashley’s face and Leslie began eating away at Ashley’s pussy. Mark and I put both of our cocks in Ashley’s mouth at the same time. She could only handle about 2 inches of each because the girth of our dicks was so large. I then took my dick out and let her suck off Mark. She wouldn’t let him cum in her mouth so she took his dick out and deepthroated mine. She wouldn’t let me cum in her mouth either so she took my dick out also and started jacking us both off until we covered her face in cum. Leslie stopped and licked all of the cum off of Ashley’s face and positioned her pussy over Ashley’s face. Ashley began eating Leslie’s pussy as Mark and I moved to Ashley’s pussy. We were going to fuck both holes. Mark positioned himself under Ashley to fuck her in the ass and I over her to fuck her pussy. I let Mark start first and he easily slid his dick in her ass. I then began to move mine into Ashley. She screamed that she was full after about three inches of my cock, but I kept going. I could feel Mark’s cock though the walls of Ashley’s pussy as he slid in and out of her. 

I pushed even further into her pussy and I was at about 6 inches when she cummed. Mark cummed shortly after with his biggest load. His cock softened to about 4 inches but it quickly hardened again in Ashley’s ass. I took this short pause to fill Ashley with my cock and my cum. When we were both hard again Ashley was being fucked by us both. We kept this up for a few minutes and we took our cocks out of my sister and It was Leslie’s turn. Leslie couldn’t take my entire cock because I reached her back walls after about 7 inches of my cock. 

We were so wrapped up in fucking each other that we didn’t hear the front door close downstairs. A minute later my 12 year old brother walked into my room. He was supposed to be staying with a friend the entire time my parents were going to be gone. He shouldn’t be home, especially not now. We all thought that we were going to be dead kids since he walked in on us, but he dropped his bags and asked if he could join. So we told him that he could under one condition, that he wasn’t going to tell anyone. This was his first time to see my cock because I had always hidden it from my family. He stripped and his cock appeared to be about 4 ½ inches, which was ok for a 12 year old. He walked over to me and compared his cock against mine and was struck in awe. I was easily double the length and double the girth. I asked him if he had ever jacked off and he said yes because the boy he spent the night with for the week had been jacking him off each night. He jacked himself off within a few minutes and blew about 3 loads. We began to give him the time of his life. 

First Ashley started off by giving him a blowjob and she swallowed what little cum he released. Leslie then let him fuck her and blow his small loads into her pussy. We then saw what he could do to a real cock. I told him to jack me off. He could barely fit both hands around my cock, let alone move them up and down enough to jack me off. Ashley then came to help him but I wouldn’t let my cum go. I had stretched my cock to the limits at about 9 ½ inches which was enough to take away the foreskin. Matt then had an idea. He straddled my cock and began to slowly push it in his ass. He could barely get the head in without wincing. We all watched in awe as my little brother slowly stretched his ass down my cock. He reached about 5 inches when I told hold of him and began to move him up and down on my cock, each time pulling him farther down. He eventually reached my full 9 inches in his ass. He then started fucking my cock and I let me largest load yet go at 16 loads. Cum was pouring out of his ass every time he moved up. He then got off of my cock and licked it clean. 

Needless to say, we had an awesome weekend until my parents came home. They never knew about our little secret and we continued with our daily lives. I still visit my sister late at night for a quick fuck and suck. We know exactly what we are going to do the next time our parents go on vacation again.
