Repressed Memories, first time story(futa loli/shota group, big cocks, lots of cum)

This is my first try at a story. Please be gentle, may be a little strange and out of order.

Repressed Memories

I just got back my psychiatrists, she told me I should write down what I remembered so I don't forget it. You see, for a while now I've been obsessed with futas, especially dominant, young futas. I went to my psychiatrists and brought this up and she was interested in finding out why. It was then that she was able to help me remember a repressed memory of when I was younger, of being fucked by some young futa girls. I had forgotten the night I had lost my virginity because I was much younger and didn't understand how it could've happened. This is what happened on that night.

I was with my family at another family's house for a long night. The other family had two daughters, at that time a 12 year old girl, Becky, and a 9 year old girl, Carolyn. Oh, by the way, I was a 14 year old boy, blond, blue eyes, a bit bigger but muscular. We were mostly there because our parents all got along, and we were just pulled together. On this night my parents ended up staying overnight in the guest room at their house, and I was stuck into the girls bedroom. This was fine with me because I had a major crush on Becky. She was stunning, thin, blond, bright green eyes, rounded hips, strong legs, everything a young girl is supposed to be. I was fairly sure she liked me too, because she would get shy around me. Now that I was spending the night in her room, with her sister, I figured it would be a good time to talk to her. When we went up to the room though, something else happened.

We got into the room and sat down to watch some TV for a while. I sat down next to Becky so I could talk to her, and her sister Carolyn immediately plopped herself into my lap. This was a little much for me because she was just as gorgeous as her sister, a younger, smaller version of her sister. Becky had small B cups, but Carolyn was almost flat. They were both gorgeous and now I was pretty much surrounded by both of them. When she sat down, Carolyn smiled up at me innocently and asked if I minded if she stayed there. I looked at Becky and it looked like she was trying to suppress her own laughter while giving me a slight nod. I told Carolyn it was fine so she stayed sitting there. Except I soon realized she wasn't just sitting on my lap, she was slowly bouncing and moving all around on my lap, I realized this and immediately got a full hardon. Even at that time I was fairly impressive, probably around 7 inches long hard, and Carolyn must've felt it pressing against her tight butt.

She sat there for a couple of minutes, still moving around a bit, before standing up at the same time as Becky. They both stood up and looked down at, one on either side.

“Ryan,” Becky said, “You have an erection from my sister, are you a pervert?”

I gaped at her and couldn't formulate a response, “I can't believe you
