*All parties are consenting and over 18*
I got invited to what was supposed to be a party, nothing big or fancy, and certainly nothing wild. A small bonfire in the yard of an old high school friend. The plan was to have a small miniature reunion of people, but I was the only one to end up showing for various reasons. I preferred it that way as it was just myself, my friend, and his girlfriend. This guy was a good person, a great friend, and a total unabashed man-whore. He had one hell of a high school reputation for sleeping around. He never did it in a mean way, he was up front with what he wanted, and polite when told no, but he definitely got around all the same.
We lit the fire in his back yard, with no fences or trees to hide us from the road, and we started drinking. It was nice getting to meet his girlfriend, we hadn't really been keeping in touch. She was average height and a little heavy, but very pretty with a soft face and eyes, and short black hair. Best of all she was very friendly, so the conversation flowed easily. We caught up on work stories, and then personal fun stories, and even skirted around sexy reminiscing, the whole time with her flirting with both of us in turn.
It was three hours in when I got up to go find a tree. He approached me and stood beside me to relieve himself as well, while she waited by the fire. I knew the two of them were swingers, but I did not expect what he said next. He told me she liked me, and wanted to do a little more since it was only the three of us. Since it was a little out of the blue, he was checking to make sure I was ok with it, and to let me know it as ok with him as well, telling me to just use her however I wanted. I absolutely did not mind, a little unexpected fun is usually the best kind, so we packed it in and went back to relax. His girlfriend waved me over and pulled me into her lap, laying a hand on my thigh while wrapping her other hand around my waist.
Soon he got up, saying he was headed inside for a few minutes, and hiked it up to the house leaving the two of us alone, and she wasted no time moving the hand further up to grab my hardening cock. I looked down and then looked back at her, and she asked if my friend had explained everything and this was ok. Such nice people. We were making out immediately after I consented, while her hand was enthusiastically exploring the bulge in my jeans. I had her by the hair as I held her head where I could keep my tongue dancing with hers, not sure exactly how proceed with my temporary girlfriend, but what I wanted quickly didn't matter, as she took my hesitation to mean she was in control.
She pushed me up and stood with me, telling me to sit down so she could get on her knees for me. With me in the comfy chair, she reached for my button and fly and pulled me free to the open air. I watched her dive onto my cock, taking my whole length in one go and holding herself down savor it. Soon she was back up long enough to tell me she loved it and went back to bobbing her lips around me. I gripped her head between my hands and watched her work, alternating between long deep throating, and teasing my tip while stroking me. She was amazing, building me quickly to a head and then easing me back down by freeing me from her mouth and licking me from stem to tip. The only thing to jar me from the hypnotic sight was a passing car, reminding me as I whipped my head to the left, that we were completely exposed to the road in the darkness, being the only things moving by the fireside. This thought alone nearly sent me over the edge, as I looked around to see who could could possibly see us, and from where. She pulled my attention back by pulling her lips away and bringing them to my balls, licking and sucking to cover them in drool as she stroked me, and waited until I was looking down at her with my plump dick resting on her face to pull up and take me back inside, locking eyes as she fucked her throat with me. I lasted through a dozen pumps before I filled her stomach.
