Me and my girlfriend were invited to one of her friend’s birthday party, we got all dressed up nice and stuff, took the car and went to the place it was supposed to go down.
The event took place in a sort of house, with a party area, and there were also rooms for the guests to remain over the night.
There were a few guests already there when we arrived, with time more and more came along. We just casually started drinking and like always i started getting frisky with her after a while(there were times when we were out with buddies of mine, drinking and I would subtly finger her under the table without anybody noticing).
We would mingle and chat to random people, and we would find ourselves from time to time in some secluded part of the location, we would make out and I would tease her, lifting her dress slightly up, and brushing my hand against her panties, then pull it back down. I always love to do this to her, and prepare her for what I have in mind for later.
