Watching Brad fuck Lisa from behind was a tremendous turn on. Brad is a good enough looking guy, tan from the waist up, pale as snow from the waist down. Lisa is made-up good looking, though I was beginning to think that she would be even prettier without all the makeup. I didn't really dwell on that thought, I was busy feeling growth of my now useful manhood as it pressed into the crack of Delinda's ass. Delinda was transfixed by the sight of her older sister getting fucked in the standing position by my best friend, not five feet from where we lay on a sleeping bag in the middle of a ryegrass field outside of Garden, Oregon.
In a flash of clarity I could replay the last four hours of my life in a series of still photographs going by so quickly it was like a moving picture. First there was Delinda bringing down the wash in the summer evening. Then there was the four of us nearly skinny dipping in the nearby trout stream. Having a community dinner from the same frying pan. Losing my virginity under billions and billions of stars, and now watching two people I have known for the last eight years copulate, unashamed. Their passion was contagious. Even though Delinda and I had just completed our first sexual experience, I could feel a primal compulsion to do it again.
My cock was now fully engorged. It was pressed into the crack of her ass and I could feel her unconsciously rotating her hips to slide it along the crevice of her sex. I am excessively endowed, but Delinda is a good sport and very limber. She was able to accommodate my length and girth with just a little initial discomfort. Now she was rubbing her engorged clit along the last three inches of my cock that was protruding from between her clenched thighs. She grabbed the head of my newly used manhood and pressed it hard into her slit, separating her labia and pushing her clit even harder against my warm prick.
Her nails dug into the tender skin under my hood and I inhaled sharply. Delinda mistook this for a sign of pleasure and did it again.
"Ouch!" I said, reaching around her hip and grabbing her by the wrist. "That's a little too tender for that!"
"I'm so sorry David," she apologized. "Let me kiss it and make it better."
She wasn't being serious when she said that and I didn't think she was actually insinuating that she would do it until she rolled me on my back and separated my knees to give her full access. While I watched Brad fucking Lisa, now Brad could watch Delinda licking my cock from tip to base. Lisa could have watched too if Brad hadn't bent her over at the waist and caused her hair to fall around her face while he assaulted her from behind.
I was suddenly aware of the noises of the night. Crickets chirping, mosquitoes whining, frogs, bats softly fluttering, the sound of my best friend's hips smacking my girlfriend's sisters ass. I giggled. So did Brad. Pretty soon we were silently cracking each other up, each making phony fuck-faces for the amusement of the other. Brad had the whole porn star look, eyes lolling, lip frozen in a snarled animalistic passion, hair tossed in the breeze. I bit my lower lip and began to nod my head in time with Delinda's mouth riding up and down on my shaft.
"Oh, yeah!" I mouthed at Brad.
This set us off again. It wasn't that it was so funny, it was that we had never been laid before and now it didn't seem like it was going to stop. Our laughter was just our exuberant expression of manhood. The girls either didn't catch on or didn't care. They never broke from their responsibilities of fuck toy and oral sex machine.
"I'm about to blow," whispered Brad.
"Wait wait wait!" I whispered back.
I pulled Delinda's mouth from my cock and pulled her on my chest. I kissed her deeply and pulled her thighs apart, allowing my cock to find it's own way into her now stretched cunt. As I slid into her, she began to melt into my chest. It was awkward, but I managed to get to my knees and then to my feet without disengaging my cock from her pussy.
Brad and I faced each other from across the small grass clearing. He was still banging Lisa from behind, I was vertically engaged with Delinda, holding her tight to my chest as she clamped her long legs behind my waist. I moved my arms up and down and she moved up and down on my pole easily.
"Any time," I mouthed at Brad.
He quickened his pace and so did I. I had never seen another man climax before, not even myself in a mirror. But I could tell he was ready to explode because I was too. He stopped screwing around and commenced to get on with real fucking. I was impaling Delinda over and over again, and my knees were buckling, a sure sign that an orgasm was building deep in my balls.
One final hard thrust and Brad locked Lisa's ass to his groin. He was shivering with excitement as he pumped his seed deep into her womb.
I took a couple more upward stabs with my own cock and sweet release was my reward. I staggered and managed to fall in such a way that Delinda wasn't hurt. She never left my cock. I rolled to my back and now she was back on my lap, fully engaged. I lifted my knees so she could rest.
She pulled her legs from under herself and lay back against my thighs. I could feel our secretions oozing past my shrinking shaft and into my pubic hair. So what, I could take a dip in the lake and get clean.
I looked over at Brad and Lisa. They had collapsed in a heap, also still engaged, him on top of her, on the sleeping bag next to us.
