A true story on how my sister and I started our long sex relationship
I have an older brother and sister, he is 12 years older than me, and she is 14 years older, so I guess you can say I was a mistake.
My story starts a long time ago, I was around 13 years old, my brother was married and in the navy. My sister married to a guy in the Army had 3 children. When her husband was deployed overseas, she and the children would come and stay at my parents’ house. Once a week Marg would take us swimming at the local public pool, I would help her to teach her children to swim. Once we finished, we would go to the family cubical to get changed, I would go in one on my own and Marg would go next door. I could stand on the seat and look over into her cubical and we would chat, this was the first time of many that I would see her naked. She was around 5ft 6in, Large breasts and a full mound of pubic hair. I did not see her as sexy, but she has a great body even after having 3 children.
On a Saturday morning I would play rugby for the school, I would come home and take a bath to get ready and play for a local club in the afternoon. One such time I was in the bath and laying back relaxing, when there was a light tap on the bathroom door, it Was Marg. She begged to come in so she could take a pee. Being a normal grouchy teenager, I objected because I was naked. Her reply took me by surprise, she said that I had seen her naked often enough, so it was only fair that she see me naked. I reached out of the bath and unlocked the door. Marg came in with a big smile on her face. She looked at me in the bath, facing me she slowly lifted up her skirt and pulled her panties down, my eyes were transfixed on her hairy pussy. She sat down on the toilet and proceeded to pee. She told me there was nothing wrong with nudity, in fact when she was at her own home, they would all often walk around naked. When she finished, she wiped and stood up giving me full view of her pussy again, slowly she pulled up her panties and lowered he skirt. She kissed me on the head and said thank you for allowing her in, and as she walked out, she said you have a nice body and that I should show it off more.
The following Saturday I was again taking my bath, Marg again knocked on the door, asking to Pee. I reached across and unlocked the door. She again slowly lifting her skirt, my eyes staring at her, no panties today, but stockings and suspenders. This was the first time I see her as sexy, my Cock started to grow, and I could see her looking at it. When she finished, she let her skirt down very slowly, she was looking and my now fully erect cock. She said to me, “looks like you enjoyed that view”, I nodded nervously. She leaned over and kissed my head, saying to me that she enjoyed her view and not to worry it was a nice complement for her. After she left, I had to play with myself giving me the most intense orgasm I have ever had.
Things changed at the swimming pool too. Although I could not use the same cubical I would stare at Marg lustfully, she knew what she was doing to me and played along by slowly drying herself and rubbing her pussy with the towel. When we got out of the cubical she would smile at me and wink, noticing my erection through my shorts.
This lasted for a couple of months, same thing on a Saturday and at the pool, I found myself wanking constantly thinking about my sister. I even thought she watched me once but could not be sure. Her husband came home from deployment, and she moved back to her army quarters. I still thought about her and wanked myself silly over her.
A year or so later, we as a family, all went to visit my brother on the coast. It was a hot summers day, and we all went to the beach. At the end of the day, we returned to my brother’s house. I went upstairs to shower and got undressed in the spare bedroom. Seconds later Marg came in, I stood there totally naked. She smiled and quickly got out of her swimsuit, this was the first time we were both totally naked in front of each other and alone. My cock sprang to attention immediately, Marg whispered Wow, is that because of me? I nodded, I really wanted her to rub it for me, but instead she slid her hand between her own legs. She suggested I go take a shower and get rid of my hard on. Disappointed, I did as she suggested. When I came out of the shower room Marg was gone.
We would see each other quite a few times but never got the opportunity to get naked, however if she knew I was going to be around, she would wear stocking and suspenders, and flash me when she could. It always ended with me having to take a trip to the bathroom.
I was now 18 and had joined the Army. My Parents, Marg and her husband attended my passing out parade, I was about to take 2 weeks leave before I joined my new unit. After the parade we all went back to my parents house, where they had arranged a surprise party for me, this meant Marg and her husband were staying over. On the night of the party Marg appeared in a black dress and I could see the outline of her suspenders through it, my cock started twitching straight away, she would tease me for the rest of the night, lightly and discreetly touching my cock through my trousers, it drove me insane, but neither of us could do anything, I was unsure if this was just teasing, or she had other ideas. The night ended with me rather drunk and being put to bed by Marg she helped my get undressed down to my boxers, she gave my cock a slow gently squeeze, before kissing me on the cheek.
I awoke the next morning, hearing everyone up and having breakfast. I went downstairs and joined them. Marg was sitting there in jeans and a light blouse; I got a good eyeful of cleavage. Her husband said to me, that now I was a fellow soldier I should visit them more often. In fact, he was going on a short exercise in a couple of days and suggested I should go down and keep Marg and the kids company for the week he was away. I could tell by Margs face that this was surprise suggestion for her too but commented that it was a nice idea and pleaded with me to go. I tried to remain calm and not look like I had just won the lottery, I of course agreed. They left later that day, before she left Marg gave me a peck on the cheek and let the back of her hand slide over my yet again growing cock.
I had to wait 2 days before going down to my sister, it could not come quick enough, I could not stop thinking about her and fantasizing what could happen, I knew I had to keep myself in check as I was still unsure if this was just teasing, but I desperately wanted to fuck her.
The day came, I could not get out of my parents house quick enough, it was a 2 hour drive and I think I had a hard on for most of the journey if not all of it.
I parked up and sprinted up to the 3rd floor of her apartment and rang the doorbell. Marg opened the door and my jaw dropped open. She stood there smiling, a tight black leather skirt and a tight white tee shirt, but no bra, I could easily see her hard nipples and the darkness of her areola. She pulled me in and kissed me on the lips, I told her she looked amazing, she thanked me for the complement, she put her finger to my lips to shush me, “My friend Brenda is here at the moment so be careful”
Marg took me into the front room and introduced me to Brenda, she was a similar Hight to Marg, she had the same sort of tight skirt on and a dark blouse, which held the biggest pair of Tits I had ever seen, outside of a porn film. Marg made coffee and we sat down, Marg and Brenda opposite me. It was then I notice that both of their skirts had ridden up a bit and I could see the tops of their stockings. I could also see the white of their panties. Both were teasing me, and my excitement was beginning to show in my tracksuit trousers. Brenda got up and went to the bathroom. Marg looked at me and said control yourself, we can both see you are hard; she then smiled and opened her legs a bit to flash me her panties. Brenda came back in the room, the top button of her blouse now undone, Margs nipples were still rock hard. Brenda sat down and her legs opened slightly, showing me her stocking tops and I could see the glistening lips of her pussy, she had removed her panties.
We talked for a bit, every now and then they would put a hand on each other knees, causing them to open their legs slightly, giving me a perfect view. I think they were both getting turned on knowing what they were doing to me. Marg stood up, cleared her throat, and offered to make more coffee, she took the cups and went to the kitchen. Brenda smiled and opened her legs, I got a full view of her pussy, which I could tell was getting wet. She whispered and asked if I liked what I was seeing, I nervously nodded my head. She spoke again and asked a straight open question, which took me by surprise. Would you fuck your sister she asked, I thought for a little bit and whispered back, I would but wasn’t sure if she would do it? Do you wank thinking about her? she asked, I didn’t reply but just nodded my head. Have you ever fucked a married woman? She asked. I replied that I had not, she asked if I wanted to, and I replied yes, I would as long as it would not cause her problems. I’m married do you want to fuck me? she asked. Again, I didn’t reply and just nodded. I heard Marg call from the kitchen that she was out of milk and was popping to the local store to get some and that she wouldn’t be long.
We heard the door close; Brenda was up and walking over to me, unbuttoning her blouse and taking it off, she stood over me and pushed me back into the sofa, she started pulling at my tracksuit bottoms, releasing my cock which was pointing at her massive tits. We don’t have much time she said, taking of her bra and offering her nipple to my mouth, she lifted he skirt and sat on my lap, she guided my cock straight into her. I could feel the warmth and wetness of her. She bounced up and down on me her breathing getting faster, I was sucking on her nipple. Fuck this feels so good she said, I could only mumble in agreement. I could feel her sliding up and down on my cock, I never had such a sensation before, it was amazing. I could feel an explosion rising up inside me, I grabbed her hips and pulled her down on me as far as I could, I fired my cum inside her, I didn’t think I was going to stop. She pulled my head into her tits and screamed as she too started to cum.
Brenda pushed my head back and kissed me full on the mouth, hard, our tongues dancing with each other. She came up for air and looked at me and said “That was fucking amazing, I don’t think I have ever cum so hard” She smiled and kissed again. “My God you are still hard” as she moved her hips on me again. “Did you enjoy that” she said smiling. I nodded. “I wasn’t talking to you” she said looking over my shoulder. I looked back behind me afraid what would happen next. There was my sister leaning on the door frame, One hand up her tee shirt on her nipple, her skirt hitch up around he waist and the other hand in her panties.
“Did you hear your brother wants to fuck you” Brenda asked Marg
quietly Marg said yes.
“Do you want him to Fuck you” Brenda asked
I was scared to hear the answer, I turned back facing Brendas huge tits, My cock still hard inside her.
I felt another hand on my shoulder, and then a kiss on the top of my head. Marg spoke quietly, “I have wanted to fuck my little brother for a long time, and I hope he always does want me to”
Marg appeared to the side of us, her hand still in her now very wet panties. What she did next surprised me but turned me on instantly. She leaned over to Brenda and kissed her full on the mouth, whilst using her free hand to pinch Brendas nipple. Brenda looked at Marg and said “I have a nice surprise for you”.
Brenda slowly got off my cock, it was still hard and dripping with our combined juices. Marg smiled and reached down for it, at last my sister was touching me, all those years I had been dreaming and wanking for this very moment.
Marg got on her knees and looked at me while she stroked my cock.
“Before we go any further, there are some rules which you must adhere to, and you must agree to them”.
I nodded
“There are 3 of us girls, who wanted to add some excitement to our lives. We wanted a male with us who we could trust. I mentioned you, who I trust with my life, I showed them some photos of you and Brenda and Sally agreed. When you were asked down here at the weekend, I knew the timing was perfect. All our husbands are away. So Brenda and I agreed to set this up, you will meet Sally tomorrow. No-one must ever know about this other than us 4, our husbands and children must never find out. You and I will have to act natural around all our family, however hard that may be. We will destroy everything if anyone finds out. We will arrange meet ups as often as we can, again these must be kept secret, if it is found out you are there then suspicions will be raised. Do you agree with all of this”?
I nodded and said that I would never do anything to hurt anyone, and that I would never want it to end, So the is no way I would tell a living soul.
“Good Boy” Marg said “now, stand up and take all your clothes off” Marg and Brenda stripped down to just their stockings and suspenders.
Marg told me to lay down on the sofa, she laid so her mouth was directly over my cock, Brenda lifted Margs hips and started to lick her from behind, Marg moaned as she lowered her mouth onto my throbbing cock.
