You would probably say that hitting on a girl when you've got a girlfriend is dangerous business. And I would agree, but I was a horny college boy and just couldn't resist the opportunity to double dip. My girlfriend's buddy was simply irresistible, and I had to try my luck.
At first, she put me off and I should have let it go and been happy she didn't tell my girlfriend about it. But she was just way too sexy, and my penis wouldn't let me give up, so I kept trying. Finally, she said agreed if I wore her panties to the party, we were all going to be at that weekend. I was a little hesitant but really wanted some of her pussy, so I agreed. It felt oddly kinky to be agreeing to wear another girls' panties and in the same kinky way I was looking forward to it. A few days before the party she gave me the panties to wear and just looking at them got me hard. They were lavender purple with little white flowers printed on them.
In an odd way even though I was nervous about wearing her panties I was also looking forward to it. Any chance I could over the days leading up to the party I pulled her panties out from my drawer where I hid them under my own undies and examined them and imagined wearing them. I could have tried them on beforehand, but my kinky mind wanted to wait until that night to slip them on.
I picked up my girl and we went to the party greatly looking forward to a side diversion at some point during the night. The silky panties felt better than I had imagined, and I barely got them up around my waist before my erection was full staff and making an impressive tent in them. This probably should have embarrassed me, but I was way too horny for this girl to care.
The party was fun, but I was getting more horny by the second with her teasing me every chance she got when my girl wasn't looking. I knew she was hot but had no idea she reveled in being a cock tease to. Adding a few drinks to the equation and I was definitely ready for a diversion. We had it all planned out where we could make a discreet exit without raising anyone's suspicions, especially my girlfriend's.
I was about to press the button on the diversion, when the party hostess suggested a round of seven minutes in heaven. Straws were quickly drawn, and the object of my desire and I were chosen. I couldn't believe my luck when she led me into the closet.
