As the k**s got older then people dropped out of the camping holidays but one family and their 2 daughters and one of their friends remained until the...eldest girl was 16. We were always at the beach during the day and had a great time. The sea got rough in the afternoon and riding the big waves was just amazing.On this holiday it was becoming clear that the eldest daughter (I shall cll her T and friend S) had really matured both physically and had become very grown up but still c***dren as. I picked her up and took her to my coffee table. I swiftly yanked her jeans and panties off and pushed her legs apart. I rubbed the head of my dick around her wet opening. She kept trying to arch herself so she could take the dick but I kept teasing her clit with my dick. I then spun her around so that she was bent over the table. I continued to tease her pussy, despite the her pleas of "put it in". I relented and put the head of my dick just inside her pussy. Maggie started the arch back but I. ..dont talk, just imagine. She just lost it, and till this day it is probably one of the most explosive orgasms we have ever had.She was humping, grinding, swearing and then it happened she shouted "Cum in me Rob...fill my cunt!" I unloaded in her wet bare cunt as she squeezed and milked me with her pussy. We both just lay there after it not saying a word and went to sleep.Over the space of the next few days we never discussed it, or even had any sexual contact, but the usual Saturday night. Here is what happened a few short days after she took my virginity from me.I walked into her room to see if she was busy and found her breast feeding. Normally she would do this with a special shirt on and sit in the family room watching TV and nobody would really notice her actions but here she was in the privacy of her bedroom she was sitting there with no shirt on at all and her beautiful breasts were exposed, well one was busy being sucked by my nephew but the other one was fully in view.
