The quiet moment continues for just a little longer until your girlfriend speaks up. "Well yeah sis. Isn't this what we came here to do. I mean, ever since you went off to college we haven't had a lot of time for each other like we use to."
You are very surprised by her answer. There was no way that you were her big sister, and yet she was talking to you like you had always been. You begin to think your little sister is playing games on you again...er, your girlfriend? No, maybe your sister. Your thoughts were becoming very confused.
"Uh sis, are you feeling ok?" she asks you, as you have been distracted by your own inner conflict. "Huh? Uhm, yeah, I think I am alright. I think I got flight lag or something. Just a little mentally exhausted I guess." You finish, but your still unsure of what is exactly going on. On one hand you know that this was your girlfriend, but on the other you know that this is your little sister. As you sit and try to sort out all of your thoughts, you don't notice your girlfriend moving closer to you.
In no time, your little sister, or girlfriend, or whatever, has you pinned on the bed, and is kissing you deeply again. This time you don't stop her. Sure it feels like incest, but your actually liking it a lot. Then a new idea hits you that seems to explain everything. She is your little sister AND your girlfriend. It all makes sense now, as she is both, which is why your loving every minute of the kiss. As you come to this realization, you close your eyes and go completely into the kiss.
While your eyes are closed a life you never knew comes flooding into your head and replaces your old life. You remember growing up very close to your little sister. You would always hold her tight when she was upset or scared. You would laugh with her when your parents wouldn't get your inside jokes. You would kiss her when she was lonely. You would love her when you both wanted to be loved. Every memory came to you of this life, and you embraced it.
When the kiss finally stopped, you opened your eyes to find yourself looking at the only person you have every fully loved, your little sister. "Well, somebody seems to be feeling better now" your sister says with a grin. "Yeah, we after you kiss somebody like that, I think anyone would feel better. However, I might need a little more to get myself going" you finish with a similar grin.
It was at that point you and your little sister went back to kissing, even more passionately than before. During the kiss, both of you slowly strip off each other's clothing until your bare bodies are rubbing against one another during your embrace. Breaking the kiss once more, your sister moves down to your breast and begins to suck and squeeze them, just as she had done some many times. The new stimulation was getting you not only hot, but wet as well. You knew what was coming next, and you were ready.
Your little sister stops her sucking and flips herself around so the both of you are now in the familiar sixty-nine position. You take a small moment to take in her smell before you start licking the lips of your sister's little flower. After you have gotten her hot as well, you begin to move your tongue inside, tasting your little sisters juices. As you are doing this, you can feel her licking and kissing your pussy as well. The two of you continue to go deeper and deeper into each other, as there is no more doubt in your mind that the two of you have always been very loving sisters. Finally you can't take the stimulation anymore, and you release your fluids into your sister's awaiting mouth. Shortly after, your sister does the same, and you do your best to lick up every little drop.
After your love making had finished, you and your little sister lay back down in a hugging embrace where you kiss and cuddle for a few minutes. Now tired, you decide that now would be a good time to take a nap before the two of you would go out and explore the resort some more. But as you are starting to drift to sleep you hear your sister speak. "Thanks sis for coming here with me. I've miss you so much." "Hey, no problem. Besides, you know I would never pass up a chance to spend time like this with you. Now get some rest, we still have a whole vacation in front of us." And with that, the two of you drift to sleep.
