Wendy, Jen and Andy had a triangle going. Wendy laid down on the grass, Andy had was on his knees fucking her and Jen sat on her face and was kissing Andy.
Aaron had moved his mouth to Bev's tits. He had begun to fuck his cock into her pussy, which made Bev very happy. The noise level had gone up a couple of decibels as Aaron started pushing harder and harder into Bev. Andy was now pile driving Wendy, which made Wendy chew harder on Jen's clit. Julie had 3 fingers buried in her own pussy and the other hand was now flying up and down on my cock with her mouth. Mom and Jill were getting louder and their climaxes were starting, then Jack started peeing on Jill's back. It was running all over their sides but some pee was running down Jill's crack and into mom's mouth. This pushed me over the edge watching them. I started cumming into Julie's mouth, which pushed Julie over the edge into her orgasm. Andy was pumping his seed into Wendy, which made Wendy cum. Wendy sunk her teeth into Jen, which pushed Jen over the edge. I was glad our only neighbor was on vacation, because with the other women moaning Bev couldn't hold it any longer. She started bucking her ass at Aaron, and her couldn't hold it either. He was pumping so hard and fast you could just tell he was filling her up.
The noise, which had been deafening was now silent. Everybody had collapsed and the only noise you heard was the deep breathing of everybody just trying to recover.
Everybody practically crawled to the pool to cool down and clean off. Jack and Mom got out of the pool and put the Hamburgs and hot dogs on. Everybody else began to get out of the pool, but nobody got dressed. The girls couldn't do anything but giggle. They were comparing notes and planning the rest of the night's activities. Even Mom seemed like a school age teenager. Sex and a cook out, what a day and it didn't seem over yet.
When we sat down to eat, Julie and Bev joined Aaron and me. They were very curious about being with another woman. Aaron dared them to kiss. The kiss was a peck on the lips.
"Come on" Aaron chided, "That was no kiss, let's see some tongue action."
Julie and Bev looked at us, then moved their lips together. Their tongues started dueling each other. Julie scooted closer and mashed her tits against Bev. Bev surprised us both by pinching and pulling on Julie's nipple. Julie returned the favor to Bev and both were getting into the kiss. You could tell something was happening. Neither of the girls was able to sit still. The kiss was becoming more passionate, their lips were getting crushed with the force of the kiss, their faces were becoming flushed and they were yanking on each other nipples. Soon, they were not even able to kiss, they could only moan. Then they collapsed.
The after dinner conversation was still giggly and off color. The men teased and told the jokes and the girls giggled. Shortly after dinner, Andy, Jen and Wendy had to leave. Aaron was like a kid in a candy store. He had three naked women he could tickle or pinch. They started pinching and grabbing his dick back. Bev, Julie, and Mom jumped him and started wrestling. Jack helped Aaron. I watched as there were tits flopping everywhere. Jack and Aaron started to get hard. Aaron got his caught between Bev and Mom and the face he made, you thought he broke it off.
I had cum so much I wasn't sure I would ever get it up again, and I sure did not want to waste energy wrestling. Jack held Bev and Julie down and Aaron began spanking Mom. His comment was "I had never gotten the chance to get the better of an adult."
The more Mom struggled the harder he spanked her. Her bottom was getting mighty red. Finally she quit struggling and he quit spanking her. He crawled up next to her and began to kiss her.
Julie and Bev were face to face when Jack let them go. They stayed just like that so they could kiss. Julie began licking and nibbling Bev's neck, then moved down her neck to her nipples. She experimented on how to lick, suck, but when she started biting Bev went to heaven. She grabbed Julie's head and held her there. It wasn't until she had an orgasm that she let Julie continue on down her body. When she got to Bev's pussy she hesitated just a moment, but continued with her exploration. Her tongue played with Bev's clit, then her pussy lips, and finally it looked like she was tongue fucking her.
Bev moved around so that she could do a little exploration of her own. It didn't take long before they were both drinking each other's cum.
When I looked over at the others I saw Jack say something to Aaron, and Aaron went into the house. Jack lay down on the grass, Mom straddled him and sunk his cock into her pussy. She had pure joy on her face. She didn't move except to lean over him and kiss him. Aaron came out carrying a jar. He opened it and put the KY in her back hole. Mom started to get up except Jack wouldn't let her. She look a little scared, but Jack whispered in her ear and was licking her neck and nibbling on her ear. Aaron crouched down, put his cock at her hole and pushed.
"Slowly" Mom yelled
Jack was talking to her quietly in her ear, and she calmed down. Aaron began to slowly fuck her ass. At the same time Jack picked up Aaron's rhythm and was fucking her pussy. Mom's face went from fright to pleasure, to ecstasy. She started rocking harder and harder against Aaron and Jack, who began to pump her. I had never heard Mom swear, but when the tempo picked up Mom got real demanding, FUCK ME, FUCK ME HARDER HARDER. She was rock'en and screaming. Aaron and Jack were pumping with all their fury. Jack's face began contorting, he grunted and shot his cum into Mom, Aaron couldn't hold off any more and started his contortions and grunting. Mom sceamed "FUCK ME HARDER" for the last time and collapsed.
Aaron moved first as he pulled out of her ass. Mom just lay on top of Jack. Jack's limp cock came out of mom and you could see cum running out of both holes.
The night ended on that note. Everybody was fucked out. It was like everybody at the same time had said uncle. I don't think anybody will forget Julie's 18th birthday, as it was the sexual awakening of my family.
