summer of being shared SeXStoRY

I was friends with a pair of twins, one of which was crippled, so I spent a lot of time at their house over the summer, after school, stuff like that. Their little s****r had always had a bit of a crush on me. It had gotten to the point where I was concerned. She was 6 years younger than me, and I wanted her to find someone her own age. So we started talking more, just the two of us, in an attempt to get her to stop carring for me. It failed, and I actually ended up falling for her. We dated on and off for 6 years, got engaged, picked out k**s names, looked into places to live together when she got out of high school, the whole thing. Bout a week before she graduated and a year before our planned wedding, I found out that the last 3 years we where together, she had been cheating on me with a guy she had always told me was "just a friend". They had also been engaged at the same time we were. Needless to say, I was crushed. I had noone to really talk to about it. About the only person who knew what happened and tried to help was her mom. For the first 6 months after my ex left, she would still come back to fuck from time to time. Her other fiance worked out of town durring the week, so she would still see me durring the week, then be all his on the weekend. A part of me thought I could win her back. A part of me just felt it was fair for her to cheat on him with me since she cheated on me with him. But since I had loss her on the weekends, my sex life took quite a hit. Her mom was always talking about how her husband wasn't a good fuck and all this other stuff. So I started to have sex with the mother as well. One night, of many, I had met the mom at her job and fucked her several times. She had a hysterectomy so I could unload gallons in her, plus she liked the taste of my cum and would swallow any that wasn't in her pussy. My ex, I didn't creampie to often because of pregnancy scares, but she always swallowed, just like mom. So one night I fuck mom 3 times at her job, first and last loads in her pussy, middle down her throat. I got home from fucking her about 2am and went to bed. I sl**p naked, and woke up 5 hours later to my ex naked in my bed sucking my dick, my dick that was just unloading in her mothers pussy. I couldn't tell if she noticed the taste of pussy on my cock, but I wasn't going to ask either. So she hops on top and gives me a good ride before drinking my cum. We then spent the day together, shopping, breakfast, back to my place to fuck twice more. She ends up leaving about 5 pm, nicely fucked with several cum loads in her stomachs. While we had our final round that day, my phone had gone off. After she left, I looked, and it was mom, not looking for her daughter, but asking if I could come fuck her again. So I got dressed and went over. I walked up and pulled my dick out, and she started sucking it, still with her daughters pussy juices on it. She noticed, cause she looked up at me puzzled, but I think she thought it was her from the night before cause she didn't stop. That was the only times I ever had them both within 24 hours, or without a shower between them, but I spent the entire summer fucking hem both. At the end of the summer, my ex told me she only kept me around as long as she did because I was a better fuck than her husband, and I had to end it with mom because she was just way too attached to me. So that's my summer of being shared.
