My story starts when our parents went on a weeklong vacation leaving us at home alone. They felt it was ok because we were both perfect student. Little did they know… I had been watching porn videos late at night for about a year and I had been jacking off for about two years. I thought my sister was perfect though in all aspects. I was partially right. Our parents left on Sunday afternoon and had arranged rides for us to school. On Monday afternoon my sister went home and I went to basketball practice after school. We had a shortened practice because the coach fell ill in the middle of practice so he called us to the showers.
We had standard shower procedures: strip, walk in, scrub, walk out, grab a towel, and get dressed. I was third in line, which cut down on the staring eyes at my massive cock. I tried to stay away from three guys near the end of the line because they were gay. I had my shower and got dressed and left the locker room just to find out about 15 minutes later that I had left my gym shorts in my locker. I went back to the locker room and found the three gay guys sucking each other off at the end of my row. I tried to avoid them but they caught me on the way out. The tallest one, Mark who also had the longest dick at about 7 ½ inches, asked me if they could see my cock so I said what the hell and I dropped my shorts to let them see my cock. Mark immediately fell and began sucking on my cock, but I backed away from him because I wasn’t gay.
I ran home, still about an hour early, to avoid the three guys for the remainder of the day. I arrived home and quietly walked through the door to keep from waking my sister up because she normally comes home to take a nap before doing her homework. I walked into my room and gently closed the door and dropping my bag, walked to my closet to sit and take off my shoes. As I sat down, I saw a hole in the wall that I had never noticed before. I moved toward it and looked through it and to my surprise I saw my sister on her bed but she wasn’t asleep. She was sitting on the bed completely nude fingering herself into a frenzy. She had a beautiful body. Her tits were nice and round, probably size 34c and her pussy was amazing. She had laid towels on the floor in front of her for a strange reason until she cummed all over the towels. Then she laid back and seemed to have fallen asleep.
I couldn’t wait at this moment so I ran to my bathroom and immediately pulled out my rock hard cock and jacked myself off. I blew 7 loads before I was finished because my sister was so fucking hot. Later that night I didn’t mention anything to my sister about her fingering herself in hopes that she might do it again. Since my parents were gone I could watch porn more openly now on my laptop so I stripped and crawled into bed and pulled the sheets over my dick. I wouldn’t be hard for a while because I had seen these movies several times. My sister then peeked into the room and mentioned that she was going to take a shower. We shared a bathroom that had a door in each of our bedrooms too.
She normally would close the door completely but tonight she left part of it ajar so I stole a look through the crack while she showered. She was beautiful in the steaming bathroom with water dripping off of her tits. She then pulled out a battery and started moving it in and out of her pussy while she showered, but she didn’t keep this up for long. She finished her shower and wrapped herself in a towel and went back to her room. I had a hardon again so I immediately went to jack off.
We both went to sleep like normal that night and woke up for school the next morning. I had my usual hardon in the morning since I slept nude because my parents never had to wake me up anymore. But unusually my sister knocked on my door that morning and asked to come in. I raised my knee up under the sheets to hide my hardon and told her to come in. She told me that breakfast was ready and for me to hurry up. She closed the door and I quickly dressed. She had made breakfast for us both. After breakfast we took our showers and we went to school and had a normal day. I saw my sister during the day and she mentioned that she was going to have a friend over to spend the night. I figured she wouldn’t finger herself tonight then. I went to basketball to find that the coach wasn’t there at all and that practice had been canceled for the next three days.
I found Mark alone this time just staring at his cock in the locker room. I asked him what was wrong and he said that his cock would never be as great as mine was and that he shouldn’t have been gay. I told him that his cock was fine as it was because I didn’t know what else to say and I invited him over to spend the night since my sister did the same. I didn’t think it would cause any damage.
Mark came home with me and we quietly went to my room and deposited our bags and shoes in my closet. I watched through the hole and in surprise found both girls fingering each other this time. I had an instant hardon and Mark noticed it because it literally stood out of my shorts. I moved and let him watch the two girls and he also had a hardon. I went towards the bathroom and found that it was locked so I couldn’t wait to jack off. Mark and I jacked in the middle of my closet and covered each other with cum. The two girls cummed a few minutes later. We couldn’t clean up the mess of cum with anything but Mark instantly went to work licking it all up off of my body.
We skipped dinner that night and went straight to bed. I didn’t mind Mark sleeping with me in my bed nude like I was as long as he didn’t try to fuck or suck me. We watched porn for about an hour before going to sleep.
We woke the next morning to hear both girls in the shower at the same time giggling about something, except this time they closed the door. We grabbed our breakfast and got to school early and had a normal day again. That afternoon we both went straight to my house before my sister left school to get there in time. We made it and was ready for her in my closet. She continued with her routine and her friend walked in a few minutes later. This was basically a replica of the previous day but we didn’t care. After they cummed the first time, they began again while Mark and I moved out of the closet to the bed to watch more porn. They cummed again, except this time some cum hit the wall near the area of the hole. Ashley found the hole and began watching me and Mark jack off. She told her friend to get to the hole and look at her brother’s massive cock. They decided that they would pay a visit to Mark and I the next day.
We continued through school for Thursday and went home like normal, except that this time my sister didn’t show up in her room. She instead came into my room with her friend. Mark and I had stripped anticipating a show. We backed up to the bed while they moved closer. I then stepped up and moved towards my sister and Mark did the same towards her friend, Leslie. Ashley then asked if she could jack me off if I would finger her. I agreed and she dove for my cock with her caressing hands. Mark received the same treatment from Leslie. Ashley had a difficult time jacking my cock because she wasn’t used to anything as big as mine. She couldn’t even fit her hand around my cock. It didn’t take long before I blew my total of 11 loads all over her and Leslie’s faces. Mark blew his 4 shortly after. We then fingered the girls until they cummed and we gladly sucked ever juice up. They left and went to bed having cummed three times. We stayed up jacking and sucking each other off because we had just fingered a girl. I was ok with Mark sucking me now.
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 ***s 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.
