When i first started i more or less just wanted to do that as cell, a big good COF. I was able to experience it a couple times, so my first fantasy was fullfilled.
Then i watched over the years many movies of college gone wild type, and i wanted to be able to experience something similar, where a party would happen and i would have sex with one of the hot girls in he bedroom of the place the party was happening, all being having a good time with alchool and stuff. I experienced the closest i could ever get to this with GG2.
I have been able to also experience a very GFE afternoon once, maybe its not really explaining much saying like that, but i know what i mean ... lol
I was also able to try greek and even tough its ok in term of fun, i can't say i "got crazy over it" but im glad i did was able to do it. Would probably partook with the right lady again if ocasion happen but im not craving bad for it.

On the fantasy list, in the possible area , i have yet to have a duo... I would like to experience this, one girl taking care of the balls, the other the penis, and a cumswap at the end...
But as for say mimick a porn scene literally... hum i would have to think about it. Most of the porn fantasy is based around a scenario. And even tough its possible to ask for role play, im not sure i would fit confortable doing so... that would be weird to me.
